           THOMPSON, Circuit Judge.

                                OVERVIEW

           Together   with    his   older   brother   Tamerlan,    Dzhokhar

Tsarnaev detonated two homemade bombs at the 2013 Boston Marathon,

thus committing one of the worst domestic terrorist attacks since

the 9/11 atrocities.1 Radical jihadists bent on killing Americans,

the duo caused battlefield-like carnage.        Three people died.     And

hundreds   more    suffered     horrific,     life-altering       injuries.

Desperately trying to flee the state, the brothers also gunned

down a local campus police officer in cold blood.             Reports and

images of their brutality flashed across the TV, computer, and

smartphone screens of a terrified public — around the clock, often

in real time.     One could not turn on the radio either without

hearing something about these stunningly sad events.

           Dzhokhar eventually got caught, though Tamerlan died

after a violent confrontation with the police.

           Indicted on various charges arising from these ghastly

events, Dzhokhar stood trial about two years later in a courthouse

just miles from where the bombs went off.       Through his lawyers, he

conceded that he did everything the government alleged.             But he

of disrespect or as a sign of familiarity but to avoid confusing
references to persons with the same last name.

insisted that Tamerlan was the radicalizing catalyst, essentially

intimidating him into acting as he had. See 18 U.S.C. § 3592(a)(4)

(providing    that   relative   culpability   is   a   mitigating   factor

relevant to the imposition of a death penalty).               Apparently

unconvinced, a jury convicted him of all charges and recommended

a death sentence on several of the death-eligible counts — a

sentence that the district judge imposed (among other sentences).

             A core promise of our criminal-justice system is that

even the very worst among us deserves to be fairly tried and

lawfully punished — a point forcefully made by the then-U.S.

Attorney for Massachusetts during a presser at the trial's end.2

To help make that promise a reality, decisions long on our books

say that a judge handling a case involving prejudicial pretrial

publicity must elicit "the kind and degree" of each prospective

juror's "exposure to the case or the parties," if asked by counsel,

see Patriarca v. United States, 402 F.2d 314, 318 (1st Cir. 1968)

— only then can the judge reliably assess whether a potential juror

can ignore that publicity, as the law requires, see United States

v. Vest, 842 F.2d 1319, 1332 (1st Cir. 1988).3             But despite a

     3 For simplicity's sake, we will occasionally call this the
"Patriarca standard."
                                  - 4 -
diligent effort, the judge here did not meet the standard set by

Patriarca and its successors.

          Another   error   forces   us   to   act   as   well,   this   one

involving the judge's denial of Dzhokhar's post-trial motion for

judgments of acquittal.     Navigating a complex and changing area of

the law, the judge let stand three of Dzhokhar's convictions for

carrying a firearm during crimes of violence, in violation of 18

U.S.C. § 924(c).    The judge thought that each of the underlying

offenses constituted a crime of violence.        But with respect (and

with the luxury of time that district judges rarely have), we

believe the current state of the law propels us toward the opposite

conclusion.

          The first error requires us to vacate Dzhokhar's death

sentences and the second compels us to reverse the three § 924(c)

convictions.   On remand, then, the district court must enter

judgments of acquittal on the relevant § 924(c) charges, empanel

a new jury, and preside over a new trial strictly limited to what

penalty Dzhokhar should get on the death-eligible counts.4               And

just to be crystal clear: Because we are affirming the convictions

(excluding the three § 924(c) convictions) and the many life

     4"Remand" is legalese for "[t]he act or an instance of sending
something (such as a case, claim, or person) back for further
action." See Remand, Black's Law Dictionary (11th ed. 2019).
                                 - 5 -
sentences imposed on those remaining counts (which Dzhokhar has

not challenged), Dzhokhar will remain confined to prison for the

rest of his life, with the only question remaining being whether

the government will end his life by executing him.

          What follows is an explanation of our reasoning, as well

as our take on certain issues that may recur on remand.5

                     HOW THE CASE CAME TO US

          The facts of today's appeal are painful to discuss.   We

apologize for their graphic detail.    We also do not attempt to

cover all of the case's complicated events in this section —

instead we offer only a summary, adding more information during

our discussion of particular issues.

                            Bombings

          On Patriots' Day 2013 — April 15, to be exact, a local

holiday celebrating the first battles of the American Revolution

— the Tsarnaev brothers set off two shrapnel bombs near the finish

line of the world-famous Boston Marathon, leaving the area with a

     5 Before going on, we wish to compliment counsel for both
sides for their helpful briefs and arguments. We never hesitate
to call out lawyers who fail to meet the minimum professional
standards expected of them.    So it is only fair that we thank
today's attorneys for their exceptional performance in this most
serious and high-profile case. And while our views on some of the
issues differ from the district judge's, we commend him for all
his hard work in very trying circumstances.
                              - 6 -
ravaged, combat-zone look.6          BBs, nails, metal scraps, and glass

fragments littered the streets and sidewalks. Blood and body parts

were everywhere — so much so that it seemed as if "people had just

been dropped like puzzle pieces onto the sidewalk" (a description

taken from a witness's trial testimony).              The smell of smoke and

burnt flesh filled the air.          And screams of panic and pain echoed

throughout the site.        "Mommy, mommy, mommy," a five-year-old boy

cried out over and over again, his leg cut to the bone.                    Others

yelled "help us," "we're going to die," or "stay with me."

              Now   brace   yourself    for    how   Marathon-goers    Krystle

Campbell, Lingzi Lu, and Martin Richard spent the last few minutes

of their lives.

              Krystle Campbell was watching the race with her friend

Karen Rand (now known as Karen McWatters) when the first bomb went

off.       Rand got knocked to the ground.           But she dragged herself

over to Campbell, burning herself on hot metal pieces as she did

so.        She put her face next to Campbell's and held her hand.

Campbell      was   "complete[ly]    mutilat[ed]"     from   the   waist    down.

Speaking very slowly, Campbell said her "legs hurt" — even though

they had been blown off.            Moments later, her hand went limp in

Rand's.      And she never spoke again, bleeding to death right there.

       6   All relevant activities occurred in Massachusetts.
                                       - 7 -
             Lingzi Lu was with her friend Danling Zhou as the second

bomb exploded.     Zhou got a gash across her stomach, requiring her

to hold her insides in.     While Lu had her arms and legs, she did

have a significant thigh injury.         "[B]asically her leg had been

filleted open down to the bone," a doctor on the scene later said.

He tried to tourniquet the wound.      But she had lost a lot of blood

and didn't have much of a pulse.         Despite knowing that she was

going to die, the doctor asked a nearby person to start CPR.           A

firefighter later moved in and pumped air into Lu's mouth with his

mask.   And a police officer did chest compressions, telling her,

"[S]tay with us.    You can do this.     You're going to be okay.   Stay

strong."   He and others put Lu on a backboard and placed her in an

ambulance.     But a paramedic told them to get her off because she

"was gone" and he needed to keep the ambulance free for those who

could be "save[d]."

             The second bomb also sent BBs and nails tearing through

eight-year-old Martin Richard's body, cutting his spinal cord,

pancreas, liver, kidney, spleen, large intestine, and abdominal

aorta, and nearly severing his left arm.       He bled to death on the

sidewalk — with his mother leaning over him, trying to will him to

live. Searching for his two other children, Martin's father, Bill,

first found son Henry (age twelve) and then daughter Jane (age

six).   Jane tried to stand up but fell — because her left leg was

                                 - 8 -
gone. Bill carried her for a bit. And then an off-duty firefighter

tourniqueted the leg, saving her life.

          Not   only   did   the    Tsarnaev     brothers   kill    Krystle

Campbell, Lingzi Lu, and Martin Richard, they also consigned

hundreds of others to a lifetime of unimaginable suffering.            Some

lost one or more limbs, blown off as they stood near the finish

line or amputated later because they were so badly mangled. Others

lost sight, still others hearing.          And years after the bombings,

many still had debris in their bodies.         One survivor had shrapnel

in her that occasionally worked its way to the surface and had to

be removed; another had a ball bearing stuck in his brain — to

give just a few examples.

                          Manhunt and Capture

          Leaving   the   scene,    Dzhokhar    and   Tamerlan     drove   to

Cambridge and stopped at a Whole Foods.        Dzhokhar went in, grabbed

a bottle of milk, paid for it, and left.        About a minute later, he

returned to the store and exchanged the bottle for a different

one.

          Back at his school the next day (UMass Dartmouth, as it

is known locally), Dzhokhar resumed his normal routine.            He worked

out with a friend at the campus gym, for example.           "I'm a stress

free kind of guy," he tweeted.

                                   - 9 -
          Aided by a description given by a man from his hospital

bed, as well as by videos from security cameras and bystanders'

cell phones, law enforcement released images of the bombers two

days later on April 18, and asked the public to help identify them

and provide information about their whereabouts.    The FBI (short

for the Federal Bureau of Investigation) produced a "wanted poster"

on its website and asked the local community to give any details

that could lead to their arrests.

          That night, still April 18, Tamerlan and Dzhokhar put

pipe bombs, a handgun, and a shrapnel bomb (similar to the ones

they exploded at the Marathon) into Tamerlan's Honda Civic and

drove off from his Cambridge home.     Passing by the Massachusetts

Institute of Technology ("MIT," from now on), they spotted the

squad car of campus police officer Sean Collier.    Approaching the

squad car from behind, the brothers shot Collier dead at close

range — twice in the side of the head, once between the eyes, and

three times in the hand.   They tried and failed to take his gun

(the holster's retention system tripped them up, apparently).

Startled by an MIT student riding by on a bike, they got back in

the Honda and sped away.

          The brothers then drove to Brighton where they crossed

paths with Dun Meng, who was sitting in his parked Mercedes SUV.

After pulling up behind him, Tamerlan got out of the Honda and

                              - 10 -
knocked on Meng's passenger window.      Meng rolled the window down.

Tamerlan leaned in, opened the door, jumped in, aimed a gun at

him, and demanded cash.    A frightened Meng handed over his wallet.

Explaining that he had exploded the bombs at the Marathon and had

just killed Collier, Tamerlan ordered Meng to drive.        So drive

Meng did.    Dzhokhar followed behind in the Honda.

             Tamerlan eventually had Meng pull over on a street in

Watertown.    Tamerlan got into the Mercedes's driver's seat.   Meng

got into the Mercedes's front passenger's seat.     And after parking

the Honda, Dzhokhar got into the Mercedes's back passenger's seat.

Tamerlan drove to an ATM.       Dzhokhar withdrew $800 from Meng's

account using Meng's bank card and PIN ($800 was the card's

withdrawal limit).

             Tamerlan drove back to his Honda to get a music CD with

nasheeds on them (nasheeds are Islamic chants).     He played the CD

in the Mercedes — music that sounded a "bit weird" and "religious"

to Meng.      Tamerlan then stopped for gas in Cambridge.     Fearing

this might be his last chance to escape, Meng made a break for it,

sprinting across the street to a different gas station where he

begged the attendant to call the police.       Tamerlan and Dzhokhar

took off in the Mercedes.

                                - 11 -
           Meng told the arriving officers that the carjackers were

the Boston Marathon bombers.     He also told them that his Mercedes

had a built-in tracking system.

           Good police work then led authorities to the Tsarnaev

brothers in Watertown, where the two had returned to get the Honda.

Tamerlan got out of the Mercedes.     Dzhokhar got out of the Honda.

Tamerlan started shooting at the officers.       And he and Dzhokhar

threw some pipe bombs and a larger bomb that looked "like a big

cooking pot."   A couple of the bombs exploded.

           After getting shot, and having possibly run out of

bullets, Tamerlan tossed his gun at one of the officers and ran

toward them.    They wrestled him to the ground, however.   Dzhokhar

got back in the Mercedes.      And while trying to make his getaway,

he ran over his brother, who died hours later.

           Also hurt in the shootout was MBTA police officer Richard

Donohue.   He nearly bled to death after a bullet hit his groin

area.   It took months in a hospital to recover from his injury.

           Back to Dzhokhar.    He could only drive about two blocks,

because the police had damaged the Mercedes's tires.    So he exited

the car and fled on foot.      In a nearby backyard, he found a boat

shrink-wrapped in plastic and climbed inside.     And he stayed there

overnight, bleeding from his wounds.

                                - 12 -
             Dzhokhar did, however, have enough strength to write a

manifesto justifying his actions.              On two wooden slats attached to

the boat he carved the words, "Stop killing our innocent people

and we will stop."          "God has a plan for each person," he wrote on

the fiberglass hull (with a pencil he found on the boat).                     "Mine

was   to    hide    in    this   boat    and   shed   light   on   our   actions."

"[J]ealous"        of    Tamerlan's     martyrdom,    he   accused   "[t]he    U.S.

Government [of] killing our innocent civilians."                   Stressing that

he could not "stand to see such evil go unpunished," he warned

that "we Muslims are one body, you hurt one, you hurt us all."

And finishing up, he wrote, "Now I don't like killing innocent

people it is forbidden in Islam but due to said [ ] it is allowed."7

             With       Dzhokhar      still    at    large,   then-Massachusetts

Governor Deval Patrick asked nearly a million citizens of Boston

and the five neighboring locales (Belmont, Cambridge, Newton,

Waltham, and Watertown) to "shelter in place" — that is, he told

them to remain behind closed doors and "not to open the door for

anyone other than a properly identified law enforcement officer."

He also asked schools and businesses to close — only hospitals and

law enforcement would stay open.

                                        - 13 -
            Later that day, on April 19, Watertown resident David

Henneberry noticed that his boat had some loose shrink wrap and

went out to fix it — by this time Governor Patrick had lifted the

shelter-in-place order, even though Dzhokhar was still a fugitive.

As Henneberry climbed up a ladder, he saw blood in the boat and a

person lying there with a hooded sweatshirt pulled over his head.

So he raced back inside his house and called 911.

            Officers responded rapidly.         And after Dzhokhar ignored

repeated requests to surrender, they threw flash-bang grenades

into the boat and fired a barrage of bullets at it.                     Officers

finally arrested him about 90 minutes after Henneberry's call.

            An   ambulance   took    Dzhokhar    to    a    hospital    where    he

underwent hours of emergency surgery to treat his injuries —

injuries that included a gunshot wound to the left side of his

face and multiple gunshot wounds to his extremities.                        Doctors

sutured his left eye shut and wired his jaw closed.                 He could not

hear out of his left ear.      He had to be intubated and took narcotic

pain meds intravenously.      FBI agents questioned him off and on for

more than 13 hours over the next 36 hours without Miranda-izing

him8   —   and   without   letting   lawyers    from       the    federal    public

       8Miranda v. Arizona says that before                      interrogating    a

       that he has the right to remain silent, that anything he
       says can be used against him in a court of law, that he

defender's office see him either.          Most questions he answered by

nodding yes or no, or by writing his responses down in a notebook.

Repeatedly, he asked for a lawyer.         But the agents told him that

he first needed to answer their questions "to ensure that the

public . . . was no longer in danger."          Exhausted and in pain, he

asked the agents several times to stop questioning him.             But the

record does not indicate whether the agents honored these requests.

At some point he told them that after the bombings, he and Tamerlan

fled Boston by car, and "[o]n the way back to Cambridge, they

stopped at a Whole Foods . . . to buy some milk" — the two "were

observing the Muslim tradition of fasting on Mondays and Thursdays

and needed milk to break the fast."

           Unsurprisingly,    the    bombings      and     their   aftermath

dominated Boston-area TV, radio, newspapers, and magazines — not

to mention web and social-media sites.          Locals quickly adopted the

"Boston   Strong"   slogan   to   convey    a    message   of   courage   and

resilience.   And the Boston Strong movement remains vibrant to

this very day.

     3591, the attorney for the government believes that the
     circumstances of the offense are such that a sentence of
     death is justified under this chapter, the attorney
     shall, a reasonable time before the trial or before
     acceptance by the court of a plea of guilty, sign and
     file with the court, and serve on the defendant, a notice
     —
          (1) stating that the government believes that the

          defendant is convicted, a sentence of death is

     and scope of the injury and loss suffered by the victim
     and the victim's family, and any other relevant
     information. The court may permit the attorney for the
     government to amend the notice upon a showing of good
     cause.

     11 Dzhokhar twice petitioned unsuccessfully for a writ of
mandamus compelling the judge to grant a change of venue (with one
judge dissenting each time). See In re Tsarnaev, 780 F.3d 14, 29
(1st Cir. 2015) (per curiam) ("Tsarnaev II"); In re Tsarnaev, 775
F.3d 457, 457 (1st Cir. 2015) (mem.) ("Tsarnaev I"). See generally
Mandamus, Black's Law Dictionary (11th ed. 2019) (explaining that
a mandamus is a "writ issued by a court to compel performance of
a particular act by a lower court or a governmental officer or
body, usu[ally] to correct a prior action or failure to act"). We
did say, though, that if a jury convicted him "on one or more of

French phrase that (roughly translated) means "to speak the truth,"

voir dire (as relevant here) "is a process through which a judge

or lawyer examines a prospective juror to see if the prospect is

qualified and suitable to serve on a jury."              See United States v.

Parker,   872 F.3d 1,   3   n.1   (1st     Cir.   2017)    (quotation    marks

omitted).    But the judge stopped Dzhokhar's counsel from asking

prospective jurors questions like "[w]hat did you know about the

facts of this case before you came to court today (if anything)?"

and "[w]hat stands out in your mind from everything you have heard,

read[,] or seen about the Boston Marathon bombing and the events

that followed it?"

            During the guilt phase of his trial, Dzhokhar's lawyers

did not dispute that he committed the charged acts.                Rather, their

guilt-phase defense rested on the idea that he participated in

these horrible crimes only under Tamerlan's influence.                      In her

opening statement, for instance, one of his attorneys said that

"[i]t was him" and that the defense would not "attempt to sidestep"

his "responsibility for his actions."                 But she said that his

terrorist path was "created by his brother."                  And in her closing

argument, she said that he "stands ready . . . to be held

responsible for his actions."           Ultimately the jury convicted him

the charges against him," he could "raise the venue argument again"
in an appeal to us. Tsarnaev II, 780 F.3d at 28.

on all counts after hearing testimony from nearly 100 witnesses

and after receiving over 1,000 exhibits.

            The jury later reconvened for the penalty phase.12   The

parties combined to present some 60 witnesses and introduce over

180 exhibits.    And after following the process just outlined, the

jury recommended the death penalty on six of the death-eligible

     12   Here is an overview of how capital sentencing works.
     Capital sentencing has two aspects: an "eligibility phase"
and a "selection phase."    See Jones v. United States, 527 U.S.
373, 381 (1999).     A defendant convicted of certain crimes —
intentionally killing the victim, for instance — can be declared
eligible for death if the jurors unanimously find beyond a
reasonable doubt that one of four intent elements and at least one
of sixteen aggravating factors are present.      See id. at 376-77
(discussing the FDPA). If they find the defendant death-eligible,
they must — during the selection phase — decide by a unanimous
vote "whether the defendant should be sentenced to death, to life
imprisonment without the possibility of release or some other
lesser sentence." 18 U.S.C. § 3593(e). To recommend death, the
jurors must determine that "all the aggravating . . . factors found
to exist sufficiently outweigh all the mitigating . . . factors
found to exist." Id. In addition to listing aggravating factors,
the FDPA also lists mitigating factors. But the FDPA also allows
the parties to offer nonstatutory factors for the jurors to
consider as well. Id. § 3592(a), (c); id. § 3593(a). The jurors,
however, can find only aggravators for which the government gave
notice, id. § 3592(c) — though they can find additional mitigators
beyond those proposed by the defense, id. § 3593(a). And while
they must find any nonstatutory aggravator unanimously and beyond
a reasonable doubt, a single juror may find a mitigator by a
preponderance of the evidence and may "consider such factor
established . . . regardless of the number of jurors who concur
that the factor has been established." Id. § 3593(c)-(d).
Ultimately, if they cannot unanimously agree on a sentence of death
or life imprisonment without release, the job of sentencing falls
to the judge, see Jones, 527 U.S. at 380-81, who must impose either
a sentence of life without release or any lesser sentence permitted
by law, see 18 U.S.C. § 3594.
                                - 21 -
counts (Counts 4, 5, 9, 10, 14, and 15).     The judge, for his part,

sentenced Dzhokhar to die, while also giving him a number of

concurrent and consecutive prison terms on the remaining counts —

including 20 life terms.

          And this timely appeal ensued.

                              DISCUSSION

          Dzhokhar's briefs raise 16 issues for review, many with

sub-issues and even sub-sub-issues.      As we have previewed already,

the judge's Patriarca-based error compels us to vacate the death

sentences and his crime-of-violence errors require us to reverse

three § 924(c) convictions.     Not only do we explain those errors

below. We also address other issues (even if just briefly) because

we know they are likely to resurface on remand.         See generally

Swajian v. Gen. Motors Corp., 916 F.2d 31, 35 (1st Cir. 1990)

(taking a similar approach in a similar situation). So our opinion

proceeds as follows.   Essentially taking the issues in the order

presented to us, we start with venue but pivot to the jury-

selection process — because the judge's promise to hold a searching

voir dire helped drive his decision to deny a venue change, but

his handling of voir dire did not measure up to the standards set

by Patriarca and other cases.     We then touch on some matters (in

varying levels of detail) that could affect how the penalty retrial

on the death-eligible counts proceeds — matters like the retrial's

                                - 22 -
location, the government's failure to disclose evidence material

to   punishment,     the      judge's    admission      of     evidence,   the

prosecution's    behavior     during    opening   statements     and   closing

arguments,    the   judge's    jury     instructions,    the    prosecution's

private communications with the judge, etc.          And we last highlight

the errors in the judge's crime-of-violence analysis (this is one

of the most complex areas of American law, we must say — which is

why even well-meaning judges and lawyers sometimes make mistakes).

                    Trial Venue and Jury Selection

             We start with Dzhokhar's claims that the judge erred in

how he handled the venue-change motions and the jury-selection

process (we have a lot to go over, so please bear with us).

                                 Background

             It is no exaggeration to say that the reporting of the

events here — in the traditional press and on different social-

media platforms — stands unrivaled in American legal history (at

                                   - 23 -
least as of today).   The highlights (or — as Dzhokhar sees some of

it — lowlights) of the coverage include:

     Starting with the bombings themselves, the reporting covered

      the carnage-filled terror scene — with the sights and sounds

      of the wounded and the dying in full display.13

     The reporting then covered the ensuing search for the bombers

      — with images of Dzhokhar leaving a backpack behind Martin

      Richard and walking away before it exploded, with Governor

      Patrick's press-conference statements about sheltering-in-

      place, and with at-the-scene videos showing agents removing

      a bloodied Dzhokhar from the dry-docked boat.

     The reporting did not get every detail right, however — for

      example, some falsely claimed that Dzhokhar scrawled "Fuck

      America" in the boat.

     Other reporting mentioned his non-Miranda-ized statements to

      agents at the hospital — statements not introduced at trial.

     The reporting also explored the lives and deaths of Krystle

      Campbell, Lingzi Lu, Martin Richard, and Sean Collier —

      touchingly describing the pain borne by their families and

      foreshadowing much of the decedent-victim-impact evidence

                               - 24 -
      that the jury would hear.     And the reporting anticipated much

      of the testimony from badly-injured survivors — though it

      sometimes spotlighted accounts from survivors who would never

      testify.

     The   reporting   captured   the   views   of   prominent   community

      members about the penalty Dzhokhar deserved.          For instance,

      the Boston Globe reported that despite his past opposition to

      capital punishment, the then-Boston mayor thought Dzhokhar

      should "serve[] his time and [get] the death penalty."           And

      the   Globe   reported as well that a former Boston police

      commissioner believed the government did the right thing in

      seeking Dzhokhar's execution, given the evidence's strength.

     More still, the reporting generated lots of stories where

      everyday people in the area called Dzhokhar a "monster," a

      "terrorist," or a "scumbag[]."        One article even asked if a

      particular photo of Dzhokhar was "what evil looks like."

                           First Venue Motion

            In June 2014, Dzhokhar moved (before jury selection) for

a change of venue, relying on this avalanche of pretrial publicity.

He essentially argued that polling data collected by his expert

showed potential jurors in the court's Eastern Division were more

likely to consider him guilty than those in the district's Western

Division, the Southern District of New York, and the District of

                                   - 25 -
Columbia.14    Convinced    that   the     circumstances    triggered   a

presumption of prejudice in the District of Massachusetts, he

"recommend[ed] the District of Columbia as the venue with the least

prejudicial attitudes."

          Opposing   this   motion,      the   government   argued   that

Dzhokhar failed to show that "12 fair and impartial jurors cannot

be found" among the Eastern Division's "large, widespread, and

diverse" populace.   The government also claimed that his expert's

analysis had a slew of problems, including the fact that courts in

other "highly-publicized trials have found" his expert's "opinions

unhelpful, misleading[,] or wrong."       And the government suggested

that "[f]ar from 'demonizing'" Dzhokhar, "the local press has

largely humanized him . . ., portraying him as a popular and

successful student and the beloved captain of his high school

wrestling team."

     14 The District Court for the District of Massachusetts sits
in Boston, Worcester, and Springfield.         For jury-selection
purposes, the District is divided into three divisions:        the
Eastern Division, which encompasses the state counties of Essex,
Middlesex, Norfolk, Suffolk, Bristol, Plymouth, Barnstable, Dukes,
and Nantucket; the Central Division, which encompasses the state
County of Worcester; and the Western Division, which encompasses
the state counties of Franklin, Hampshire, Hampden, and Berkshire.
Boston is in Suffolk County.      Cambridge and Watertown are in
Middlesex County. So these three cities are part of the Eastern
Division, for example.
                               - 26 -
          Applying the factors outlined in Skilling v. United

States, 561 U.S. 358 (2010), the judge denied Dzhokhar's motion in

September 2014.15   Among other points, the judge noted that the

district's Eastern Division has about "five million people," with

many of them living outside of Boston — so, he emphasized, "it

stretches the imagination to suggest that an impartial jury cannot

be successfully selected from this large pool of potential jurors."

And, the judge wrote, neither the defense expert's polling nor his

newspaper analysis "persuasively show[ed] that the media coverage

has contained blatantly prejudicial information that prospective

jurors could not reasonably be expected to cabin or ignore."

Moreover, some of the expert's results, the judge stressed, clashed

with Dzhokhar's "position" because they showed that respondents in

other jurisdictions were almost as likely to believe him guilty as

respondents in Massachusetts's Eastern Division.       Also, while

"media coverage ha[d] continued" in the 18 months since the

bombings, "the 'decibel level of media attention,'" the judge said

(quoting Skilling), had "diminished somewhat."     For the judge,

     15On the presumption-of-prejudice issue, the factors Skilling
discussed included the size and characteristics of the community
where the crime happened; the nature of the pretrial publicity;
whether the passage of time had lessened media attention; and the
outcome of the case. See id. at 382-83. According to Skilling,
"[a] presumption of prejudice . . . attends only the extreme case."
Id. at 381.
                              - 27 -
Dzhokhar had "not proven that this [was] one of the rare and

extreme cases for which a presumption of prejudice is warranted."

"[A] thorough evaluation of potential jurors in the pool," the

judge continued, "will be made through questionnaires and voir

dire sufficient to identify prejudice during jury selection."

             Second Venue Motion, First Mandamus Petition,
                 And Joint Proposed Jury Questionnaire

             A few months later, in December 2014, Dzhokhar filed a

second venue-change motion, protesting that a huge portion of the

Eastern Division (again, the pool from which his jury would be

drawn) "has been victimized by the attack on the Marathon and the

related   events"   —   which,   combined   with   the   continuing   press

coverage, made it impossible to seat an impartial jury. Responding

to this motion, the government argued that "most of the articles"

Dzhokhar mentioned in this memo "have little or nothing to do with

this case, and the ones that do are largely factual and objective

in nature."    Without waiting for the judge's ruling on the second

motion, Dzhokhar — also in December 2014 — petitioned this court

for mandamus relief.     See Tsarnaev II, 780 F.3d at 17 (discussing

timeline).

             With Dzhokhar's petition pending, however, the judge —

now in early January 2015, and after construing the motion as one

for reconsideration of the original venue-change denial — rejected

his second venue-change bid (just days after he filed his mandamus
                                  - 28 -
petition).         See id.     Of note, the judge again expressed his

confidence        that   the       voir-dire       process        would    ensure    jury

impartiality. "Should [that] process . . . prove otherwise," wrote

the judge, "the question of transfer can obviously be revisited."

Still in early January 2015, a divided panel of this court then

denied Dzhokhar's petition, concluding that he had "not made the

extraordinary showing required to justify mandamus relief."                          See

Tsarnaev I, 775 F.3d at 457.

                While all this was going on, the parties — in December

2014 — submitted a joint proposed questionnaire for use in voir

dire.        Some of their suggested questions touched on the potential

jurors' general thoughts about capital punishment.                        Others touched

on their exposure to pretrial publicity — questions like:                           "What

did you know about the facts of this case before coming to court

today (if anything)?"16

                In a separate legal memo, the defense — citing Morgan v.

Illinois,       504 U.S. 719    (1992)     —   moved     to    add    more   specific

questions to identify those prospective jurors who could consider

imposing a life sentence not just abstractly, but in the particular

circumstances of the case before them.                One proposed question, for

example, asked potential jurors to

        From now on we refer to questions of this type as "content-
        16

specific questions" (or some variant).
                                        - 29 -
     [s]tate whether you agree or disagree with the following
     statements:
     The death penalty is the ONLY appropriate punishment for
     ANYONE who:
     A. murders a child.   □ Agree    □ Disagree
     B. deliberately   murders   a   police   officer.   □   Agree
        □ Disagree
     C. deliberately commits murder as an act of terrorism.
        □ Agree □ Disagree

Dzhokhar's team wanted these questions to "probe for a common form

of bias — the belief that the death penalty should always or

automatically be imposed     for certain types of murder."           The

government opposed.    Relying on and quoting Morgan, the government

argued that the defense could ask "whether 'they will always vote

to impose death for conviction of a capital offense'" generally —

not "whether they will consider a sentence less than death" in

response to "a laundry list of potential crime elements and

aggravating factors."      And according to the government, these

questions were nothing but impermissible "stakeout questions" —

i.e., questions aimed at getting potential jurors to "stake out a

position on the death penalty" before receiving instructions on

the law.   But according to the defense, "these are the opposite"

of stakeout questions since "they seek only to probe whether

jurors' minds are open to considering all of the evidence relevant

to sentenc[ing]." The judge, however, decided not to include these

                                 - 30 -
questions on the questionnaire, saying he would cover those topics

in voir dire.17

                The judge also focused on the jointly-proposed question

asking what potential jurors knew "about the facts of this case

before coming to court today (if anything)."                        Conceding that this

question "might get very interesting answers," the judge worried

that it could "cause trouble because it will be so unfocused."

"But if you want to live with it," the judge said to defense

counsel, "this is a question that we'll probably be asking every

voir dire person."

                Despite      having       had      a    hand     in     submitting      the

questionnaire, the government now switched gears and argued that

the question could cause the parties to have to "follow[] up on

every        fact   asserted"      —   something       that    "would    take   forever."

Apparently persuaded by the government's argument, the judge —

after noting that the query could generate "unmanageable data" —

ultimately          struck   the       question,       explaining     that     prospective

jurors'        "preconceptions"         could   instead        be     gauged    by   asking

whether, "[a]s a result of what you have seen or read in the news

media, . . . you [have] formed an opinion" about Dzhokhar's guilt

or the proper penalty, and if so, whether "you [can] set aside

       Going forward, we will call these kinds of questions, as a
        17

shorthand, "case-specific questions."
                                           - 31 -
your opinion and base your decision . . . solely on the evidence

that will be presented to you in court."      The defense objected,

saying that "in a case like this[,] where . . . you really have no

idea what the juror may have swirling around in [his or her] head,

it makes the juror the judge of [his or her] own impartiality."

"To a large extent that's true," the judge countered, but "the

other questions will help us" see if the potential jurors can set

aside any preconceived notions about the case — which is "the

biggest issue in voir dire, obviously."

             Start of Jury Selection, Third Venue Motion,
                     And Second Mandamus Petition

            Around the beginning of January 2015, 1,373 potential

jurors showed up at the John Joseph Moakley U.S. Courthouse for

the start of jury selection.      The judge divided them into six

panels.    As a preliminary matter, the judge twice told them that

Dzhokhar was "charged in connection with events that occurred near

the finish line of the Boston Marathon . . . that resulted in the

deaths of three people."     And the judge had them fill out a 100-

question questionnaire covering their backgrounds, social-media

habits, exposure to pretrial publicity (the amount they had seen,

whether they had "formed an opinion" about guilt or punishment,

etc.), and thoughts on the death penalty.18   The questionnaire also

     18   To give but one example, question 73 asked:
                                - 32 -
gave a "summary of the facts of this case," including that "two

bombs exploded . . . near the Boston Marathon finish line" and

that "[t]he explosions killed Krystle Marie Campbell (29), Lingzi

Lu (23), and Martin Richard (8), and injured hundreds of others."

"MIT Police Officer Sean Collier (26) was shot to death in his

police car," the questionnaire's summary added, and Dzhokhar "has

been charged with various crimes arising out of these events."

The questionnaire then asked prospective jurors their views on the

death penalty for someone convicted of intentional murder and

whether they could "conscientiously vote for life imprisonment

without the possibility of release."

             The   judge   and   the    parties   identified   the    potential

jurors by numbers.     On appeal the parties focus on #138, #286, and

#355.    So we do too.

             Before   having     the    prospective   jurors   fill    out   the

questionnaires, the judge gave some instructions.              For instance,

he told them "not to discuss this case with your family, friends[,]

or any other person."       They could "tell others that you may be a

        How would you describe the amount of media coverage you
        have seen about this case:
        ___ A lot (read many articles or watched television
        accounts)
        ___ A moderate amount (just basic coverage in the news)
        ___ A little (basically just heard about it)
        ___ None (have not heard of case before today)
                                       - 33 -
juror in the case," he also said, and could "discuss the schedule

with your family and employer." But he warned them "not to discuss

anything else, or allow anyone else to discuss with you anything

else until you have been excused, or if you're a juror, until the

case concludes."         And he told them not to "communicate about this

case or allow anyone to communicate about it with you by phone,

text, message, Skype, email, social media, such as Twitter or

Facebook."

             As    for    the   answers   potential     jurors   gave    on   the

questionnaires, Dzhokhar — for reasons that will shortly become

clear — directs us to these replies by #138, #286, and #355.

             Responding to a questionnaire inquiry about social-media

use, #138 wrote that he used Facebook "[e]very other day" at

"most."    And he wrote "N/A" for a question asking whether he had

"commented on this case . . . in an online comment or post."

             For her answer to the same question about social-media

use, #286 wrote that she looked at Facebook, Instagram, and Twitter

"daily" but did not "post daily." For her response to the question

about whether she had "commented on this case . . . in an online

comment or post," she wrote "don't believe I have."              And she wrote

"N/A" to the question asking her to explain if she or a family

member    had     been   "personally    affected   by   the   Boston    Marathon

                                       - 34 -
bombings or any of the crimes charged in this case (including being

asked to 'shelter in place' on April 19, 2013)."

          On his jury questionnaire, #355 disclosed that he worked

as an "attorney."     Answering a question about his death-penalty

views, he wrote, "Since it is legal, it should be the rarest of

punishments.    It is much too prevalent in the country."     On a scale

of 1 to 10, with 1 meaning "that the death penalty should never be

imposed" and 10 meaning that it should be imposed for all cases of

"intentional murder," he circled 2.       He circled another answer

option that read, "I am opposed to the death penalty but I could

vote to impose it if I believed that the facts and the law in a

particular case called for it."       He also wrote that "[k]illing

people, especially gov't sponsored killing, is generally wrong" —

"[w]hile I can imagine a scenario where facts and law call for it,

it is an exceedingly rare case."      And responding to the question

"[i]f you found [Dzhokhar] guilty and you decided that the death

penalty   was   the   appropriate   punishment   .   .   .,   could   you

conscientiously vote for the death penalty," he checked the box

for "I am not sure" — and then explained, "I cannot possibly

prejudge his guilt or potential punishment at this stage."

          After both sides agreed to excuse many of the 1,373

potential jurors, the judge called back 256 for individual voir

dire — which lasted 21 days.    And much happened during that time.

                                - 35 -
Dzhokhar continued to ask the judge to ask prospective jurors case-

specific questions (like the ones mentioned above) — but to no

avail.    For instance, Dzhokhar proposed that the judge ask them if

they would automatically impose the death penalty if the defendant

"killed     a    child    by   deliberately      using     a     weapon    of    mass

destruction"; "us[ed] a weapon of mass destruction to carry out an

intentional killing"; "deliberately committed an act of terrorism

that killed multiple victims"; or "intentionally murder[ed] a

police officer in the line of duty."            They "know that this is about

a bombing," the judge ruled, "and they know that there are three

people who were killed in the bombing."                    Plus they have "my

preliminary instructions, . . . telling them what the offenses

were in general," the judge said.            And, the judge stressed, "they

have those specifics already in their minds as they . . . answer

the question about the ability to meaningfully consider life

imprisonment."         The judge thought, too, that "detailed questioning

about what the juror thinks he or she knows about the events" could

create the "wrong emphasis" and might inadvertently create bias

where none existed before.

            Dzhokhar also asked the judge to ask content-specific

questions       about    pretrial   publicity    (like     the    ones    mentioned

earlier)    —    for    example,    "What   stands   out   in     your    mind   from

everything you have heard, read[,] or seen about the Boston

                                      - 36 -
Marathon bombing and the events that followed it?"19             But the judge

rejected that request, saying that "[w]e have detailed answers in

the questionnaire concerning . . . exposure to the media"; that he

saw no need to "repeat" questions "covered in the questionnaire";

and that he thought "digging for details . . . will not likely

yield reliable answers."

              Near the end of January 2015, #138 underwent individual

voir dire.      The judge reminded him that he had told "everyone to

avoid any discussion of the subject matter of the case with

anybody," though they "could talk about coming here, obviously,

but . . . also [had] to avoid any exposure to media articles about

the case."      And the judge asked #138 if he had "been able to do

that."     "Yeah," #138 replied, "I haven't looked at anything" or

"talked to anybody about it." The judge then turned to the subject

of #138's Facebook use (presumably as a follow-up to #138's

questionnaire answers).         "What's the nature of your use of it,"

the   judge    asked,   "[i]s    it   essentially   personal,     social-type

things?"       And #138 said, "Yeah."          Asked by the judge if he

"comment[ed]     on   public    affairs   or   anything   like    that,"   #138

       This was a paraphrase from a question in Skilling. See 561
19
U.S. at 371 (noting that the defendant there asked the district
court to ask prospective jurors "'what st[ood] out in [their]
minds' of 'all the things [they] ha[d] seen, heard or read about'"
the company the defendant had worked for (alterations in
original)).
                                      - 37 -
answered, "Yeah, I see what my friends are doing and comment on

that."   Which prompted the judge to ask if anyone was "commenting

about this trial" — to which #138 replied, "No."

           The same day as #138's individual voir dire, Dzhokhar

filed a third venue-change motion.     Highlighting statistics based

on questionnaire answers, he noted (among other arguments) that

out of a pool of 1,373 prospective jurors, 68% thought he was

"guilty, before hearing a single witness or examining a shred of

evidence at trial," and 69% "have a self-identified connection or

expressed allegiance to the people, places, and/or events at issue

in the case." "Stronger" evidence "of presumed prejudice in Boston

is difficult to imagine," he wrote. And as far as he was concerned,

"[g]iven the extent of prejudice and personal connections," the

judge could not count on voir dire to get "a jury that is both

actually impartial and preserves the appearance of impartiality."

           Disagreeing with Dzhokhar, the government argued (among

other assertions) that Dzhokhar's own survey showed "that nearly

100% of respondents in Springfield, New York City, and Washington,

D.C. said they had been exposed to publicity about this case."

That makes sense, the government added, because "[t]he bombings

and their bloody aftermath" made national and international news.

And, the government emphasized, the percentage of people who

believe Dzhokhar is guilty is greater in those locales than in the

                              - 38 -
Eastern Division (according to the jury questionnaire responses):

"84% in Springfield, 92% in New York City, and 86% in Washington,

D.C."   Also, according to the government, "of the 68% of potential

jurors in this case who have formed an opinion that [Dzhokhar] is

guilty, fully 60% said they could set aside that opinion and decide

the case solely on the [trial] evidence."              So as the government

saw it, the questionnaires and voir dire could protect Dzhokhar's

right to an impartial jury.

             Before the judge ruled on the motion, Dzhokhar filed a

second mandamus petition with us in early February 2015.                   But

individual voir dire still continued.            During her turn — and

responding to questions from the judge (who was following up on

her questionnaire answers) — #286 disclosed that she used Facebook,

Instagram, and Twitter "just [for] social" purposes.                 "I watch

TV," she explained, "and kind of tweet while I'm watching TV with

other   people    that   are   watching   the   same    programs    that   I'm

watching."     And she implied that she had not been "locked down"

with her family — saying that while at work on April 19, she

"jok[ed]" with her boss that she had to go home.                   "I live in

Boston," she said, "and Boston was on lockdown.           I'm, like, I have

to go home.      We're on lockdown."      Defense counsel then asked her

if any family or friends had talked with her "about the Marathon

bombing[s] . . . [o]r any of the events of that week."               "[M]aybe

                                  - 39 -
in general or something but not really," she said.       Dzhokhar's

lawyer then asked, "Can you tell us what stands out in your mind

that you read" about the case?    But the government objected.   And

the judge sustained the objection.

           A day later, with Dzhokhar's mandamus petition still

pending, the judge denied Dzhokhar's third venue-change motion —

"for reasons both old and new."    We focus here on the judge's new

reason.   Conceding both that "[c]hecking a box" on a questionnaire

"may result in answers that appear more clear and unambiguous than

the juror may have intended or than is actually true," and that

handwritten "answers" frequently "can . . . be unclear, inapposite,

or incomplete," the judge concluded that the voir dire underway

was "successfully identifying potential jurors who are capable of

serving" fairly and impartially.

           A week after the judge's ruling, #355 was individually

voir dired.   #355 said that he did not think that his work as a

criminal lawyer would affect his impartiality.      "[I]f asked to

vote on" the death penalty," he explained, "I would probably vote

against it because of my belief that it is overused."   But he later

added that "[i]f, after hearing the [judge's] instructions, and if

I believed it . . . fit into one of those rare cases where I

believed the death penalty should be imposed, having understood

the law as given to me, then . . . I could vote to impose the death

                              - 40 -
penalty."     Asked by the government whether he could "imagine any

case that [he] would think is appropriate for the death penalty,"

#355 said, "I think Slobodan Milosevic was close, if not a prime

example."20    Asked by the defense whether he could "actually vote

to impose" the death penalty in an appropriate case, #355 stated,

"I think I could."    "Are you pretty confident of that answer?" the

defense asked.    "Yes," #355 replied.

            The government moved to strike #355 "for his bias" as a

criminal defense lawyer and "for his death penalty answers."        To

the   government's   way   of   thinking,   #355   was   "substantially

impaired" because "the only time . . . he could think that he could

impose the death penalty would be in a case of genocide."          The

defense opposed the motion, pointing out that #355 said he could

"make a decision" to impose the death penalty "in a given set of

facts."     The judge granted the motion, however.        "I would not

exclude [#355] because of his . . . criminal defense work," the

judge noted.      But relying on his "sense of him," the judge

concluded that #355 was not adequately "open to the possibility of

the death penalty" — especially given "the genocide issue," which

made #355's "zone of possibility . . . so narrow" that he was

       A former president of Serbia, Milosevic led a campaign of
      20

genocidal aggression during the Balkan wars of the 1990s.    See
Slobodan Milošević, Wikipedia (last visited July 23, 2020),
https://en.wikipedia.org/wiki/Slobodan_Milo%C5%A1evi%C4%87.
                                - 41 -
"substantially impaired."         All in all, the judge was not convinced

that #355 "was going to be truly open in the way that would be

necessary."

             In     the   last   week   of    February   2015,   the   judge

provisionally qualified 75 prospective jurors — a group that

included #138 and #286.          The judge ended up excusing 5 of the 75

for hardship.       And it was from this group of 70 that the parties

would choose a jury.

             That same week, a divided panel of this court denied

Dzhokhar's second mandamus petition because he had not shown a

clear and indisputable right to a venue change (which is what he

had to show to get mandamus relief).          See Tsarnaev II, 780 F.3d at

15, 19-20.    To give one of the panel majority's reasons:         Although

Dzhokhar argued that we had to "presume prejudice for any jury

drawn from the Eastern Division of Massachusetts," the panel

majority found that "his own statistics reveal that hundreds of

members of the [jury pool] have not formed an opinion that he is

guilty" — and "[t]he voir dire responses have confirmed this."
Id. at 21.        The panel majority also believed that a rigorous and

thorough voir dire would secure an impartial jury.          See id. at 21-

24.

                       Motions to Excuse #138 and #286,
                 Fourth Venue Motion, and Peremptory Strikes

                On the same day Tsarnaev II came down, Dzhokhar filed

motions to strike #138 and #286 for cause from the provisionally

qualified jury pool — motions premised on alleged newly discovered

information.21

                In his motion against #138, Dzhokhar claimed that he had

just learned that #138 "was dishonest . . . about comments on

Facebook" and had defied the judge's "instructions" within mere

"hours     of    receiving   them."      For     support,   he    pointed    to   the

following:

     On    the    day    #138   went   to   court    to    complete   his    juror

      questionnaire, he posted on Facebook, "Jury duty....this

      should       be    interesting...couple        thousand     people    already

      here."22

     Two of his Facebook "friends" responded.                   One said, "How'd

      you get stuck going to Boston?"             The other said, "Did you get

      picked for the marathon bomber trial!!!???                 That's awesome!"

       Dzhokhar says in his brief to us that "the defense exercised
      21

diligence   in  investigating    the   1,373"   potential   jurors,
"scour[ing]" their "social media profiles" as best they could,
given the other "extraordinary demands" on his lawyers' time —
"including the ongoing jury selection process, discovery review,
litigation of pre-trial motions, and trial preparation."

grammar, and punctuation that appear in the original messages.
                                        - 43 -
    #138 replied, "Ya awesome alright haha there's like 1000s of

    people."

   Over the next few hours, people left more comments, saying

    things like, "If you're really on jury duty, this guys got no

    shot in hell" and "They're gonna take one look at you and

    tell you to beat it."

   Despite hearing the judge's preliminary warnings — "not to

    discuss anything else, or allow anyone else to discuss with

    you anything else until you have been excused," not to

    "communicate about this case or allow anyone to communicate

    about it with you by phone, text message, Skype, email, social

    media, such as Twitter or Facebook," etc. — #138 returned to

    the Facebook thread later that day and posted, "Shud be crazy

    [Dzhokhar] was legit like ten feet infront of me today with

    his 5 or 6 team of lawyers...can't say much else about it

    tho...that's    against     the   rules."     His    Facebook    friends

    responded,    "Whoa!!";     "Since   when   does    [#138]   care   about

    rules?"; and "Play the part so u get on the jury then send

    him to jail where he will be taken care of."             #138 replied,

    "When   the    Feds   are    involved   id    rather    not     take    my

    chances...them locals tho...pishhh ain't no thaang."                   "Yea

    super careful," a Facebook friend wrote back, "bc should you

                                  - 44 -
      get picked any mention of anything can get you booted or call

      for mistrial."

Dzhokhar argued that these actions by #138 showed "a willingness

to flout the rules, a lack of maturity, and a failure to appreciate

the seriousness of these procedures."      So he asked the judge to

"excuse[]" #138 "for cause."

           Dzhokhar's motion against #286 claimed that "[a]fter her

voir dire questioning," he discovered information about #286's

social media "postings at the time of the Boston Marathon Bombings

and their aftermath" that undermines "her juror questionnaire"

answers.   He emphasized the following:

     On the day of the bombings, #286 tweeted, "Need something to

      make you smile and warm your heart after today's tragedy at

      #BostonMarathon, take a look at #BostonHelp."     About Martin

      Richard, she tweeted, "Little 8yr old boy that was killed at

      marathon, was a Savin Hill little leaguer :-( RIP little man

      #Dorchester #bostonmarathon."     #286 was from Dorchester too

      (Dorchester is a neighborhood in Boston).

     During the shelter-in-place situation, #286 tweeted that she

      was "locked down" with her family, adding, "it's worse having

      to work knowing ur family is locked down at home!!     Finally

      home locked down w/them #boston."

                               - 45 -
     After   Dzhokhar's   capture,   #286    retweeted    expressions   of

      celebration — including a tweet that said, "Told y'all.

      Welcome To Boston The City Of CHAMPS!       We get our shit DONE!

      #BostonStrong."         Another    of      her      retweets   said,

      "Congratulations to all of the law enforcement professionals

      who worked so hard and went through hell to bring in that

      piece of garbage."   And another of her retweets read, "Monday

      started in celebration and ended in tragedy.          Today began in

      tragedy and ended in celebration.        You can't keep us down.

      #BostonStrong."

     Over the following year, #286 retweeted additional posts

      about the victims — including retweets of a photo of Martin

      Richard's sister singing the national anthem at Fenway Park

      (home to the Boston Red Sox), a photo of Martin's older

      brother running the Boston Athletic Association Youth Relay

      Race in 2014, and photos of officers Sean Collier and Richard

      Donohue at their police academy graduation (the caption over

      the photos read, "Please keep both in your prayers").

Dzhokhar contended that #286's tweets and retweets showed "a

community allegiance that is certain to color her view of the

case," making her claim that she could fairly and impartially

"consider life versus the death penalty at trial exceedingly

                                - 46 -
suspect."     So he asked the judge to "excuse[]" #286 "for cause" or

"recall[]" her "for follow-up questioning."

            In a memo opposing Dzhokhar's motions, the government

called his challenges to #138 and #286 untimely because he did not

object when the judge provisionally qualified them.            And that

untimeliness, said the government, could not be excused based on

newly discovered evidence because the motions relied on "social

media postings . . . that predated voir dire, often by years."       On

the merits, the government asserted that #138 did not disobey the

judge's instructions by "simply reporting that [Dzhokhar] was ten

feet in front of him at one point and had a team of five or six

lawyers" (though the government did not address how #138 told the

judge during individual voir dire that his Facebook friends were

not "commenting" on the "trial").         And as for #286, labeling her

tweets and retweets "innocuous," the government argued that she

"may   well     not   have   considered    'tweeting'   (or   especially

'retweeting') a photograph to be the same as 'comment[ing] on this

case in a letter to the editor, in an online comment or post, or

on a radio talk show'" (the government made no mention of her

"piece of garbage" retweet or her being "locked down" with her

family, however).

                                 - 47 -
           The   judge   orally   denied   Dzhokhar's   motions   at   a

conference the first week of March 2015.        "I reviewed the jury

questionnaires," the judge said, and the voir dire

     transcripts. First of all, I agree with the government
     that the objections are late and it is — we have a
     procedure. We have done it with some care and taken the
     time to do it. And I think the time to raise the issues
     was in the course of that process and not thereafter.
     So I am not inclined — and will not — reopen the voir
     dire for late discovery matters that could have been
     discovered earlier.

Continuing on, the judge added that he found Dzhokhar's objections

"largely speculative."    "There are various possible explanations,"

he said,

     and none of them is . . . serious enough to warrant
     changing   our   provisional   qualification,   and   in
     particular, none of the issues that were raised seem
     . . . to suggest the presence of a bias that would be
     harmful to jury impartiality in this case.       They're
     collateral matters about things, they are — people close
     to them may have done, but none of them speak to actual
     bias in the case. So we leave the roster as it is.

           Around this time — early March 2015 — the defense filed

a fourth venue-change motion — essentially arguing that of the 75

provisionally qualified jurors, 42 "self-identified . . . some

connection to the events, people, and/or places at issue in the

case"; 23 "stated . . . that they had formed the opinion that

[Dzhokhar] 'is' guilty, with . . . 1 . . . of those . . . 23

stating . . . that he would be unable to set aside that belief";

and that 48 "either believe that [Dzhokhar] is guilty, or have a

                                  - 48 -
self-identified connection, or both."           The government opposed,

contesting     (among   other   things)   the    defense's   statistical

methodology.

             While that motion was pending, the defense used all 20

of its peremptory strikes, see Fed. R. Crim. P. 24(b)(1), but did

not strike #138 or #286 (the judge denied the defense's request

for 10 more peremptories).23        The government used all of its

peremptory challenges too.       Both #138 and #286 got on the jury

(#286 ultimately served as the jury foreperson).       Of the 12 jurors

seated by the judge, 9 got there without disclosing the specific

content of the media coverage they had seen24 — recall how the

judge rejected the defense's efforts to learn not just whether

prospective jurors had seen media coverage of this case but what

specifically they had seen.      And of those 9, 4 believed based on

pretrial publicity that Dzhokhar had participated in the bombings.

     23 A peremptory challenge is defined generally as "[o]ne of a
party's limited number of challenges that do not need to be
supported by a reason unless the opposing party makes a prima facie
showing that the challenge was used to discriminate on the basis
of race, ethnicity, or sex." See Challenge, Black's Law Dictionary
(11th ed. 2019) (second definition).
     24 The defense asked one of the seated jurors what "st[ood]
out in [her] mind, if anything, about this case from anything
you've heard, seen."     She replied, "The only thing that I
definitely can remember from that time is probably after the fact
when they showed the finish line."         Another seated juror
volunteered that she had watched "the shootout in Watertown" on
TV. And another seated juror volunteered that she had seen "video
evidence" and Dzhokhar's "being in the boat."
                                 - 49 -
But all 12 did say that they could adjudicate on the evidence as

opposed to personal biases or preconceived notions.

               On the first day of trial — also in early March 2015 —

the    judge     orally    denied    the    defense's      pending      venue-change

request, without an on-the-spot explanation.

                           Basic Appellate Arguments

               Dzhokhar presents a raft of venue- and juror-selection

claims on appeal.

               Starting with venue, Dzhokhar contends that his trial in

the district's Eastern Division violated his constitutional right

to an impartial jury for either of two reasons:                    "The community's

exposure to the bombings and ensuing pre-trial publicity . . .

warranted       a    presumption      of    prejudice,"       or       "the    jurors'

questionnaire        and   voir     dire   responses       establish[ed]        actual

prejudice."         Hoping to counter that claim, the government argues

that   "[p]rejudice        should   not    be   presumed    in     a   venue   with   a

population of almost five million and where more than half of the

prospective jurors had either not prejudged guilt or had stated

under oath that they could set aside their view that [Dzhokhar]

was guilty."         And the government also insists that the record

                                       - 50 -
nowhere shows that the pretrial publicity "actually biased" the

potential or seated jurors.

           From there, Dzhokhar argues that both #138 and #286 lied

under oath during voir dire about their social-media postings.

And, he says, by not striking them for cause, the judge robbed him

of his constitutional rights to due process, an impartial jury,

and a reliable sentencing decision.        The government responds that

even if #138 and #286 "had fully disclosed everything" that

Dzhokhar says "they should have, they would not have been stricken

for cause."     Which is why the government thinks that Dzhokhar

"cannot show entitlement to a new trial or an evidentiary hearing."

           Dzhokhar then argues that the judge stacked the deck

against him by excusing #355 based on the mistaken belief that

#355's death-penalty views would have "substantially impaired" him

in his ability to perform as a juror.         Calling him "[a]n educated

professional    who   had   devoted"   considerable     thought   to    the

question, Dzhokhar notes that #355 said that he could vote for the

death penalty in the right case — despite his personal views on

capital punishment.      Conversely, the government contends that #355

"gave   hesitant   and   carefully   hedged   answers   about   the    death

penalty," plus "was unable to think of any category of crimes

beyond genocide where he believed the death penalty would be

appropriate."

                                  - 51 -
            Penultimately (at least for this part of this opinion),

Dzhokhar faults the judge for "taking a crabbed view of Morgan."

The nub of his complaint is, to quote his brief, that a faithful

application of Morgan required the judge to ask prospective jurors

"whether they could take into account mitigating evidence and

consider a sentence of life imprisonment not just in the abstract,

but in light of specific allegations in his case."                   Unpersuaded,

the government sees no legal error under Morgan, because the

suggested questions "were impermissible 'stakeout' questions" that

basically asked potential jurors "to prejudge the appropriateness

of the death penalty in this case without consideration of the

[judge's]     instructions       or    mitigating     factors."          And,    the

government    adds,     even    if    Morgan    required   the   judge    to    tell

prospective jurors about "certain case-specific facts," Dzhokhar's

suggested questions were unnecessary because they already knew

about   the    case's     key    facts     from    the     judge's    preliminary

instructions and the juror questionnaire — "and they could have

considered those facts when answering questions about their views

on the death penalty."

            Relying on Patriarca and its offspring, Dzhokhar lastly

argues here that the judge erred in denying his request to ask

potential jurors content-specific questions about "what they had

seen, read, or heard about his case."              The pretrial publicity, he

                                       - 52 -
writes (quoting Patriarca), created a "'significant possibility

that   jurors    [had]   been   exposed      to   potentially   prejudicial

material'" and so "trigger[ed]" a "duty to inquire."                 Which,

according to him, means that the judge had to ask "not just whether

prospective jurors had seen media coverage of this case, but what,

specifically, they had seen."        And by not doing so, the judge (in

Dzhokhar's      words)   produced    "a   jury    biased   by   prejudicial

publicity."     Trying to meet this argument, the government — citing

Mu'Min v. Virginia, 500 U.S. 415 (1991) — principally contends

that Supreme Court precedent "reject[s] the claim that such an

inquiry is required."

                                Analysis

          We start, as the parties do, with the judge's decision

not to change venue — a decision that receives abuse-of-discretion

review.   See United States v. Casellas-Toro, 807 F.3d 380, 385

(1st Cir. 2015).     Anyone alleging an abuse of discretion faces an

uphill climb.     See generally United States v. Rivera-Carrasquillo,

933 F.3d 33, 44 (1st Cir. 2019) (explaining that a judge abuses

his discretion "if no reasonable person could agree with the

ruling"), cert. denied, No. 19-7879 (Apr. 20, 2020).            And that is

certainly true when a party asks us to critique a denial of a

motion grounded on alleged jury partiality, because — as no less

an authority than the Supreme Court has said — "[i]n reviewing

                                    - 53 -
claims of this type, the deference due to district courts is at

its pinnacle."       Skilling, 561 U.S. at 396 (emphasis added).

            Two of us find serious points against Dzhokhar's venue-

change arguments.

            First, the polling data shows that many in Boston were

undecided about whether Dzhokhar should receive death — even after

all the publicity.      The defense expert's own survey data revealed

that only 36.7% of people in Boston favored the death penalty for

Dzhokhar before the trial, leaving 63.3% undecided or leaning

against death.       Since the Eastern Division has a population of

about five million, that leaves several million people (even minus

children, etc.) open to a life sentence despite all the publicity.

The data from the voir-dire questionnaire is even more telling,

showing that only 23% of the prospective-juror panel had formed an

opinion that Dzhokhar should die — and just 16% held that view and

said they could not be convinced otherwise.             This means that of

the   1,373    potential    jurors,      over   1,000   of    them   had   not

predetermined that death was the right sentence.

            Second, the same polling data shows public awareness and

attitudes     were    not   materially     different    in,    for   example,

Springfield or New York City.      In Springfield, 51.7% said Dzhokhar

was "definitely guilty" and 32.2% said he was "probably guilty"

based on the pretrial publicity, compared with 47.6% and 44% in

                                  - 54 -
Manhattan, and 57.8% and 34.5% in Boston.              The numbers regarding

penalty are also similar — in fact fewer respondents preferred

life without the possibility of parole in Springfield (45.4%) than

in Boston (51.2%).

           Also and importantly, the polling inquiry does not ask

respondents to judge for themselves whether they are biased.                Nor

does it fail to overlook subliminal biases.            Instead, the pollster

asked whether Dzhokhar should get the death penalty.                The answer

to that question likely reflected whatever actual bias might have

been operating, knowingly or otherwise.               So (extrapolating from

the relevant figures) the fact that so many hundreds of thousands

in the pool of potential jurors were undecided, and that the

percentage of those persons was not materially less than the

percentage for New York City, does support the judge's venue

decision in a powerful way.

           We   note   too   that   this   is   not    a   case   where   almost

everybody locally knows something and very few elsewhere know of

it.   Plus the data seemingly contradicts any claim that the Boston

Strong movement and the sheltering in place account for undue

prejudice — were it otherwise, the difference in attitudes would

probably be much greater in, for example, New York City.

           Third, most of the publicity was true — something we now

know from Dzhokhar's guilt admission in his lawyer's guilt-phase

                                    - 55 -
opening and closing statements (notably, Dzhokhar does not say he

would have raised an innocence defense in another venue).      See

Murphy v. Florida, 421 U.S. 794, 802 (1975) (noting the truth of

the pretrial publicity); see also Skilling, 561 U.S. at 382-83;

Casellas-Toro, 807 F.3d at 387.   So after the first day of trial,

a juror from Boston and one from California would know essentially

the same things about the case — even though the California juror

would have seen less of the publicity.   Contrast that with Rideau

v. Louisiana, 373 U.S. 723 (1963), where an inadmissible taped

confession by a guilt-contesting defendant was televised only on

the local news.   As for the untrue pieces of publicity, they seem

trivial given the true and relevant information — for example, the

report that Dzhokhar's boat message said "fuck America" got quickly

disproved once jurors saw the actual message; and at any rate, the

words "fuck America" added very little if anything to what he

actually wrote.

          Fourth and finally, comparing Dzhokhar's case to other

venue-change cases — specifically Skilling and Casellas-Toro —

makes it hard to say the judge abused his discretion.     Starting

with the size and diversity of the metropolitan area (the first

Skilling factor), Boston is very large and diverse — much closer

to Houston in Skilling, 561 U.S. at 382 (a "large, diverse pool"

of 4.5 million eligible jurors in the area made the "suggestion

                              - 56 -
that 12 impartial individuals could not be empaneled . . . hard to

sustain"), than to the Indiana community in Irvin v. Dowd, 366
U.S. 717, 719 (1961) (about 30,000 people), or to Puerto Rico in

Casellas-Toro, 807 F.3d at 386 ("a compact, insular community" of

3 million people that "is highly susceptible to the impact of local

media" (quotation marks omitted)).           The nature of the publicity

(the second Skilling factor) was, as discussed, largely factual

and the untrue stuff was no more inflammatory than the evidence

presented at trial.        As to passage of time (the third Skilling

factor), two years had elapsed between the crime and the trial —

which is closer in magnitude to the four years in Skilling (a point

cutting   against     a    venue   change)   than   the   two    months    in

Casellas-Toro (a point favoring a venue change).          And the verdict

shows no affirmative signs of bias (the fourth Skilling factor),

since the jury recommended Dzhokhar die for six of seventeen death-

eligible counts, similar to Skilling's acquittal on certain counts

and   contrasted    with   Casellas-Toro's    guilty   verdict   on   counts

lacking sufficient evidence.        Dzhokhar asks us to give no weight

to the jury's decision not to recommend death on most of the death-

eligible counts.     He reasons that the jury's decision-making can

be explained by the fact that the government can only kill him

once.   But the jurors had seventeen death counts to consider.            And

they decided on death for six of those.          That selectivity cannot

                                   - 57 -
be explained (as he presumes) by his the-government-can-only-

execute-me-once theory.    For if he were right, the jury would have

returned a death verdict on just one count.      To pick six and not

one or seventeen, the jurors must have had some other rationale in

mind that required them to draw distinctions between facts that

they thought warranted a death verdict and those that they thought

did not.   And that sort of nuance favors a view of the jury as

intent on following the law and the facts.

           Dzhokhar's chief argument — that the nature of the crime

(terrorism) might be viewed as an attack on the Boston community

specifically — does not appear in the framework of these cases.

But it seems just as likely that a juror in, say, New York City

would view the crime as an attack on all of America (as he himself

did) — thus negating any advantage in changing venues.

           So if pressed to decide the venue question now, two of

us would likely find the judge abused no discretion in finding

venue proper in Boston in 2015.         But we need not make such a

decision now.   That is because, as explained next, we must remand

the penalty-phase portion of this trial for a retrial — regardless

of how we rule on venue.   And it also is because, given the sizable

passage of time, the venue issue should look quite different the

second time around, likely in 2021.       See Skilling, 561 U.S. at

383.

                               - 58 -
             Now      for        our    remand-for-a-penalty-phase-retrial

explanation.       Even assuming (favorably to the government) that the

judge did not reversibly err on the venue question, he still had

to oversee a voir-dire process capable of winnowing out partial

jurors through careful questioning — indeed, in denying Dzhokhar

a venue change, the judge premised his analysis in part on a pledge

to run a "voir dire sufficient to identify prejudice."25                     But

performance    fell     short     of   promise,     providing   (as   Dzhokhar's

counsel said at oral argument) a sufficient ground to vacate his

death sentences — even on abuse-of-discretion review.26               See United

States v. Casanova, 886 F.3d 55, 60 (1st Cir. 2018). See generally

United States v. Connolly, 504 F.3d 206, 211-12 (1st Cir. 2007)

(noting that "an erroneous view of the law" is always an abuse of

discretion).       With the venue assumption in place, we lay out our

reasoning.

             Patriarca      is   the   key.     A   pretrial-publicity     case,

Patriarca involved an organized-crime prosecution where the press

called one of the defendants "'Boss' of the New England 'Cosa

then deciding the appeal on another basis, see In re Horseshoe
Entm't, 337 F.3d 429, 435 (5th Cir. 2003); Emrit v. Holland &
Knight, LLP, 693 F. App'x 186, 186-187 (4th Cir. 2017) (per
curiam).

death sentences.

Nostra'" and reported how a lawyer for a government witness nearly

died in a car-bomb incident.        See 402 F.2d at 315-16.      Convinced

that   the   news   accounts    might   make    prospective   jurors   think

(wrongly, apparently) that the defendants had something to do with

the bombing, the defense teams moved to change the trial's venue

— and lost. Id. at 316-17.

             The defendants appealed, relevantly arguing that the

judge "erred in denying" the change-of-venue motion "because of

prejudicial publicity." Id. at 315.     We noted "that the amount of

coverage diminished sharply after the week following the bombing."
Id. at 317.     We also noted that the defense had the chance "to

mitigate any possible effect of pretrial publicity — [namely,] on

the voir dire." Id.   Counsel for one of the defendants had asked

the judge to "ask a question of the jury in connection with this

case, in the light of all the publicity." Id. at 317-18.   And the

judge said that he would ask the jurors "if there is any member

. . . who feels that he would not be able to give the defendants

a fair and impartial jury." Id. at 318.     Counsel said "thank you."
Id.    The judge put the question to the jury, got "[n]o response"

from the members, and so saw no reason not to proceed to trial.

See id.      Given this set of circumstances, we found no sign of

abused discretion in the judge's venue decision. Id.

                                   - 60 -
               But crucially, we felt "bound" to address "sua sponte"

— i.e., without prompting from either side — the scope of voir

dire judges should conduct "[i]n cases where there is, in the

opinion of the [judge], a significant possibility that jurors have

been        exposed   to    potentially     prejudicial       material." Id.

Specifically, we directed that

       on request of counsel, . . . the [judge] should proceed
       to examine each prospective juror apart from other
       jurors and prospective jurors, with a view to eliciting
       the kind and degree of his exposure to the case or the
       parties, the effect of such exposure on his present state
       of mind, and the extent to which such state of mind is
       immutable or subject to change from evidence.
Id. (double emphasis added).

               And    in   driving   this   directive    home,    we   explicitly

endorsed section 3.4 of the American Bar Association's then-recent

(emphasizing that "we are in accord with the suggestions of section

3.4").27        Section 3.4, in turn, said that in cases involving

prejudicial pretrial publicity, voir-dire "questioning shall be

conducted for the purpose of determining what the prospective juror

has read and heard about the case."              See Am. Bar Ass'n, Standards

            The rationale for the Patriarca standard is obvious.

Decisions   about   prospective   jurors'   impartiality   are   for   the

judge, not for the potential jurors themselves.      See, e.g., United

States v. Rhodes, 556 F.2d 599, 601 (1st Cir. 1977).        And that is

because prospective jurors "may have an interest in concealing

[their] own bias" or "may be unaware of it."       Smith v. Phillips,

455 U.S. 209, 221-22 (1982) (O'Connor, J., concurring); see also

Sampson v. United States, 724 F.3d 150, 164 (1st Cir. 2013)

("Sampson II") (emphasizing that "a person who harbors a bias may

not appreciate it and, in any event, may be reluctant to admit her

lack of objectivity").    So asking them only "whether they had read

anything that might influence their opinion" does not suffice, for

that question "in no way elicit[s] what, if anything," they have

"learned, but let[s] [them] decide for themselves the ultimate

     28 This standard has endured for 50-plus years. See Am. Bar
Ass'n, Fair Trial and Public Discourse, Standard 8-5.4 (2016)
(stating that "[i]f it is likely that any prospective jurors have
been exposed to prejudicial publicity, they should be individually
questioned to determine what they have read and heard about the
case and how any exposure has affected their attitudes toward the
trial"),                        available                       at

question whether what they [have] learned had prejudiced them."

Rhodes, 556 F.2d at 601.

           With these principles in mind, we have held that a judge

in a high-profile case "fully complied with" Patriarca by asking

potential jurors if they "had read or heard anything about the

case in the newspapers, on television[,] or radio" — and if so, by

"prob[ing] further as to the extent of such knowledge." See United

States v. Medina, 761 F.2d 12, 20 (1st Cir. 1985) (emphasis added).

We have also found "no inconsistency" with Patriarca when a judge

in   another   high-profile   case   "asked   the   prospective   jurors,

collectively," if they "had heard 'anything at all' about the case"

— and then asked those who had "to recount" at side bar "all that

[they] knew about the case."    See Vest, 842 F.2d at 1332 (emphasis

added).   And we have held that a judge in yet another high-profile

case satisfied Patriarca when he asked potential jurors if they

"had seen or read anything about the case" — and then asked those

who had about "the circumstances under which [they] had been

exposed to publicity."   See United States v. Orlando-Figueroa, 229
F.3d 33, 43 (1st Cir. 2000) (emphasis added).

           Despite his best intentions, Dzhokhar's judge did not

meet the Patriarca standard, however — even though the case met

Patriarca's conditions for requiring extensive inquiry.       Dzhokhar,

do not forget, "request[ed]" voir dire on the contents of the

                                - 63 -
material that the potential jurors had seen.            See Patriarca, 402
F.2d at 318.      And there was "a significant possibility" that the

prospective jurors had been "exposed to potentially prejudicial

material."    See id.   Again, the pervasive coverage of the bombings

and the aftermath featured bone-chilling still shots and videos of

the Tsarnaev brothers carrying backpacks at the Marathon, of the

maimed and the dead near the Marathon's finish line, and of a

bloodied Dzhokhar arrested in Watertown (to name just a few).

Also, while the media (social, cable, internet, etc.) gave largely

factual accounts, see Tsarnaev II, 780 F.3d at 21-22, some of the

coverage included inaccurate or inadmissible information — like

the details of his un-Miranda-ized hospital interview and the

opinions of public officials that he should die.

             With Patriarca's prerequisites satisfied, the judge had

to ascertain not just the "degree" but the "kind" of "exposure to

the   case   or   the   parties"   that     the   prospective   jurors   had

experienced, see 402 F.2d at 318 — that is, "what [they] ha[d]

read and heard about the case," see Am. Bar Ass'n, Standards

Relating to Fair Trial and Free Press § 3.4(a), at 130 (cited in

Patriarca, 402 F.2d at 318).       But as to 9 of the 12 seated jurors,

the judge fell short on this front.               To repeat what we wrote

earlier, the judge qualified jurors who had already formed an

opinion that Dzhokhar was guilty — and he did so in large part

                                   - 64 -
because they answered "yes" to the question whether they could

decide this high-profile case based on the evidence.            The defense

warned the judge that asking only general questions like that would

wrongly "make[]" the potential jurors "judge[s] of their own

impartiality" — the exact error that the Patriarca line of cases

seeks to prevent. But the judge dismissed the defense's objection,

saying    that   "[t]o   a   large   extent"   jurors   must   perform   that

function.    Yet by not having the jurors identify what it was they

already thought they knew about the case, the judge made it too

difficult for himself and the parties to determine both the nature

of any taint (e.g., whether the juror knew something prejudicial

not to be conceded at trial) and the possible remedies for the

taint.    This was an error of law and so an abuse of discretion.

See Connolly, 504 F.3d at 211-12; see also Mangual v. Rotger-

Sabat, 317 F.3d 45, 61 (1st Cir. 2003) (echoing the truism that

"[i]t is an abuse of discretion for the district court to apply an

erroneous standard of law").

            The government offers a number of arguments to the

contrary.    But none of them changes the result.

            The government first argues that the Patriarca language

we bank on is "dicta."29      True, the pertinent appellate claim there

     29"Dictum" — the singular of "dicta" — "is a term that judges
and lawyers use to describe comments relevant, but not essential,
to the disposition of legal questions pending before a court."
                              - 65 -
concerned a venue-change denial.       See 402 F.2d at 315.     But after

rejecting that claim, we "fe[lt] bound" to address the sufficiency

of the voir dire — which we did by stating that in high-profile

cases, district judges "should proceed to examine each prospective

juror . . . with a view to eliciting the kind and degree of his

exposure to the case." Id. at 318 (emphasis added).        And as a

later case confirms, Patriarca intended to and does state "the

standards of this circuit."     See Medina, 761 F.2d at 20 (emphasis

added).   So the government's dicta argument does not work.

           Nor does the government's suggestion that the voir dire

here actually "elicit[ed] the kind and degree" of the potential

jurors' exposure to the case. In making this claim, the government

(paraphrasing the questionnaire) notes that prospective jurors had

to   disclose   "what   newspapers,   radio   programs,   and   television

programs [they] viewed and with what frequency, as well as how

much media coverage [they] had seen about the case."             And that

suffices, the government says, because we have not read Patriarca

to require content-specific questioning.         But this is wrong for

several reasons.    For one thing, learning that prospective jurors

read, say, the Boston Globe daily and have seen a lot of coverage

See Doughty v. Underwriters at Lloyd's, London, 6 F.3d 856, 861
(1st Cir. 1993), abrogated on other grounds by Quackenbush v.
Allstate Ins. Co., 517 U.S. 706 (1996).
                                 - 66 -
about the case is not the same as learning that they read Globe

articles    quoting    civic   leaders       saying   Dzhokhar      should      die   —

statements    that    could    not      constitutionally      be    admitted      into

evidence.     See Bosse v. Oklahoma, 137 S. Ct. 1, 2 (2016) (per

curiam).     For another thing, the government's rejoinder rests on

a misreading of Patriarca — an opinion that does require inquiry

into what information potential jurors have been exposed to.

Again, Patriarca endorsed the ABA's standards calling for content-

specific questioning "for the purpose of determining what the

prospective juror has read and heard about the case."                      Also and

critically,    post-Patriarca           caselaw   clarified    that    the      defect

Patriarca aimed to cure was delegating to prospective jurors the

job of evaluating their impartiality — a defect that content-

specific    questioning     can    fix.      See   Vest, 842 F.2d   at    1332.

Consider Vest.    Following the correct approach, the district judge

there did not ask potential jurors "to decide for themselves the

'ultimate question' of impartiality" — instead, "once a juror

admitted to any knowledge of the case," the judge "individually

questioned" him or her "as to the facts and extent of such

knowledge." Id.         And     contrary    to      the     government's

characterization, Vest concerned not just individual versus group

voir dire, but also content-specific versus noncontent-specific

questioning.

                                        - 67 -
             Quoting Mu'Min, the government then makes its biggest

argument — namely, that this post-Patriarca opinion by the Supreme

Court (emphasis ours) "rejected the argument that the Constitution

requires   [judges]   to   question   prospective   jurors   'about   the

specific contents of the news reports to which they had been

exposed.'"    But there is a major flaw in the government's theory.

Mu'min arose on direct review of a state-court criminal conviction

— which meant the Supreme Court's "authority" was "limited to

enforcing the commands of the [federal] Constitution." 500 U.S.

at 422 (emphasis added).     Dzhokhar, contrastingly, was "tried in

federal court[]" — and thus was "subject to" the "supervisory

power" of the federal appellate courts.     See id. (emphasis added).

And this distinction makes all the difference, because "[w]e enjoy

more latitude in setting standards for voir dire in federal courts

under our supervisory power than we have in interpreting" the

federal Constitution "with respect to voir dire in state courts."

See id. at 424 (italics omitted); see also Kater v. Maloney, 459
F.3d 56, 66 n.9 (1st Cir. 2006) (noting that Mu'Min "carefully

distinguished between constitutional requirements which states

must meet and the exercise of its broader supervisory authority

over cases tried in federal courts").

             Patriarca did not say that the endorsed standard sprang

from the Constitution.     And neither did Patriarca explicitly say

                                - 68 -
that it emanated from our supervisory powers — yet we see plenty

of signs that it did indeed emanate from that source.                             For

starters, neither side in Patriarca made voir dire an issue.                      And

it     is   highly    unlikely     that   we    would   have      engaged    in     a

constitutional excursion without prompting by the parties.                    Also

and     relatedly,       given     the     well-entrenched         doctrine        of

constitutional avoidance, it is equally unlikely that we would

have gone out of our way to issue a constitutional decision.                      See

Am. Foreign Serv. Ass'n v. Garfinkel, 490 U.S. 153, 161 (1989)

(per    curiam)      (explaining   that   the    doctrine    counsels       against

issuing "unnecessary constitutional rulings").                   Plus as we have

noted, Patriarca relied on the ABA standards.             And those standards

are    meant   as     templates    for    courts,   not     as    constitutional

pronouncements.        Cf. Br. of Am. Bar Ass'n as Amicus Curiae at 2,

Martinez v. Ryan, 566 U.S. 1 (2011) (No. 10-1001), 2011 WL 3584754,

at *2 (explaining that the ABA Standards for Criminal Justice

"represent a collection of 'best practices' based on the consensus

views of a broad array of professionals involved in the criminal

justice system").         Mu'Min itself recognized that other federal

appellate courts have mandated content-specific questioning in the

exercise of their discretionary supervisory powers, not as a matter

                                     - 69 -
of constitutional law.   See 500 U.S. at 427.30   One of those courts

— the Fifth Circuit — later specifically said that "Mu'Min does

Here is a sampling of those cases' key statements:
     Because "the nature of the publicity as a whole raised a
      significant possibility of prejudice," the district court
      "should have determined what in particular each juror had
      heard or read and how it affected his attitude toward the
      trial, and should have determined for itself whether any
      juror's impartiality had been destroyed." Davis, 583 F.2d at
      196.
     Because "the publicity surrounding the instant case was
      tremendous," creating a "possibility" that prospective jurors
      "had formed opinions before they entered the courtroom," the
      district court "had a duty to inquire into pretrial publicity
      on voir dire" — and the court's "general inquiry into whether
      there was any reason [they] could not be fair and impartial
      . . . was not expressly pointed at impressions [they] may
      have gained from reading or hearing about the relevant
      events." Dellinger, 472 F.2d at 375.
     "[W]hether a [prospective] juror can render a verdict based
      solely on evidence adduced in the courtroom should not be
      adjudged on [his] own assessment of self-righteousness" — and
      given the amount of pretrial publicity, the district court
      should have made "a careful, individual examination of each
      of the jurors involved, out of the presence of the remaining
      jurors, as to the possible effect of the articles" they had
      read.    Silverthorne, 400 F.2d at 639 (quotation marks
      omitted).
     Invoking "our supervisory powers over the district courts in
      this circuit, . . . we recommend" that district judges ask
      content-specific questions in cases involving "a significant
      possibility that [prospective jurors] will be ineligible to
      serve because of exposure to potentially prejudicial
                               - 70 -
not abrogate" that court's earlier holding "that, where pretrial

publicity creates a significant possibility of prejudice, the

district court must make an independent determination of the

impartiality of jurors."    United States v. Beckner, 69 F.3d 1290,

1292 n.1 (5th Cir. 1995) (discussing Davis).

          The government also defends some (not all) of the judge's

reasons for declining to ask content-specific questions.              But

concerns about "unmanageable data" from content-specific questions

— in a case where 1,373 prospective jurors each completed a 100-

question questionnaire and the judge designated 21 days for voir

dire — seem misplaced.   So too does any fear that content-specific

questioning could accidentally create bias where none existed.         If

potential jurors recall a particular piece of reporting well enough

to bring it up at voir dire, and the reporting is prejudicial,

then potential bias was already present.       Far from "reinforc[ing]

potentially       prejudicial     information,"         content-specific

questioning would have brought such material front and center.

The parties and the judge could then assess the publicity's effect

on the prospective jurors' ability to reach a fair verdict, thus

putting the judge in a position to take any necessary measures to

protect Dzhokhar's fair-trial rights.

     material."     Addonizio, 451 F.2d   at   67   (quotation   marks
     omitted).
                                 - 71 -
               Patriarca was a noncapital case, unlike Dzhokhar's.                   And

the pretrial publicity in Patriarca pales in comparison to the

pretrial publicity surrounding Dzhokhar's case.                    Surely then, with

his life at stake, Dzhokhar deserved the type of voir dire that

Patriarca calls for.          See generally Sampson II, 724 F.3d at 159-

60   (suggesting      that    protections      are    generally         heightened   in

capital cases, because death is different from other kinds of

penalties).

               In denying Dzhokhar mandamus relief on the venue-change

issue,    it    is   reasonable     to     infer   that     the       mandamus   panels

reasonably expected that the judge would conduct the kind of

searching       voir-dire    inquiry       required    by    our      caselaw.       But

regrettably, we conclude that his efforts fell short for the

reasons just stated.           Dzhokhar's appellate counsel admitted at

oral argument that this error was harmless at the guilt stage,

given his trial concession (through his trial lawyer) that he had

done what the government accused him of doing.                         The government

suggests that "any error was harmless" at the penalty stage too,

because prospective jurors said that they could serve impartially.

Not only does the government push a theory that clashes with our

caselaw   —     caselaw     that   again    says   that     in    a    situation   like

Dzhokhar's, a judge cannot delegate to potential jurors the work

of judging their own impartiality.                    But the government never

                                       - 72 -
explains how its flawed argument proves the error's harmlessness

beyond     a   reasonable    doubt.       See    18   U.S.C.      § 3595(c)(2)(C)

(providing that "[t]he court of appeals shall not reverse or vacate

a sentence of death on account of any error which can be harmless"

if "the [g]overnment establishes beyond a reasonable doubt that

the error was harmless").31            So the government's harmless-error

theory is a nonstarter.

               Given our ruling that the judge's Patriarca-based error

demands vacatur of the death sentences,32 the remaining issues

listed above (in the "Basic Appellate Arguments" section) require

only the briefest discussion — but discussion nevertheless, at

least on matters that may arise again on remand.

               Regarding   Dzhokhar's    claim    that     #138   and   #286   lied

during voir dire, we repeat a point made in our caselaw again and

again (and again) because it is so very important to our system of

justice:       If a defendant "com[es] forward" at any point in the

litigation      process    "with   a   'colorable     or    plausible'"    juror-

misconduct claim, "an 'unflagging duty' falls to the district court

     31 Proof beyond a reasonable doubt is evidence that lets a
rational "factfinder . . . reach a subjective state of near
certitude of the guilt of the accused." See Victor v. Nebraska,
511 U.S. 1, 15 (1994) (quoting Jackson v. Virginia, 443 U.S. 307,
315 (1979)).
     32Vacatur is "[t]he act of annulling or setting aside."                   See
Vacatur, Black's Law Dictionary (11th ed. 2019).
                                       - 73 -
to investigate the claim."    United States v. French, 904 F.3d 111,

117 (1st Cir. 2018) (quoting United States v. Zimny, 846 F.3d 458,

464 (1st Cir. 2017)), cert. denied sub nom. Russell v. United

States, 139 S. Ct. 949 (2019).   See generally Sampson II, 724 F.3d

at 169 (stressing that "[j]urors who do not take their oaths

seriously threaten the very integrity of the judicial process").

But our decision on the content-specific-questioning issue makes

it unnecessary to address the misconduct charge.33

          And that same ruling also makes it unnecessary to touch

on Dzhokhar's argument that the judge wrongly excused #355 for his

views on the death penalty.

          That leaves us with Dzhokhar's claim that the judge kept

him from asking case-specific death-penalty questions critical to

seating an impartial jury — questions like whether potential jurors

could consider mitigating circumstances on the ultimate life-or-

death issue, given "the specific allegations in his case:       the

killing of multiple victims, one of them a child, in a premediated

     33 Citing French, 904 F.3d at 120, Dzhokhar briefly argues
that any error regarding juror misconduct would require vacatur of
his convictions as well as the death sentence. But this case is
unique in that Dzhokhar's counsel admitted his guilt in the opening
and closing statements of the trial's guilt phase, and he has not
argued that he would have used a different trial strategy in
another venue or before a different jury. At oral argument here,
Dzhokhar's lawyer conceded that this guilt admission would allow
us to affirm the convictions despite the alleged juror-misconduct
error — or any other error, including venue. We agree.

act of terrorism."        On this issue — which also gets abuse-of-

discretion review, see Casanova, 886 F.3d at 60 — it is enough for

us to say that even assuming without deciding that the judge had

to inform prospective jurors of certain case-specific facts, he

did do so here.      Recall the judge's preliminary instructions to

prospective jurors before they filled out the questionnaires —

that Dzhokhar was "charged in connection with events that occurred

near the finish line of the Boston Marathon . . . that resulted in

the deaths of three people."              Recall too the questionnaires'

"summary of the facts of this case" — that "two bombs exploded

. . . near the Boston Marathon finish line[,] . . . kill[ing]

Krystle Marie Campbell (29), Lingzi Lu (23), and Martin Richard

(8), and injured hundreds of others"; that "MIT Police Officer

Sean Collier (26) was shot to death in his police car"; and that

Dzhokhar "has been charged with various crimes arising out of these

events."     And like the judge, we think that because potential

jurors    knew   these   details,   the    voir   dire   adequately   covered

Dzhokhar's case-specific questions.34

     34 Dzhokhar argues that Ham v. South Carolina, 409 U.S. 524
(1973), prevents us from so holding. We see things differently,
however.
     The state in Ham tried a locally known African-American civil-
rights activist on a marijuana-possession charge. Id. at 524-25.
He defended on the theory that the police had framed him as payback

include questions aimed at racial prejudice. Id. at 525-26 & n.2
(noting that the proposed questions asked whether prospective
jurors could "fairly try this case on the basis of the evidence
and disregarding the defendant's race," whether they had "no
prejudice against negroes" or "[a]gainst black people," and
whether they "would . . . be influenced by the use of the term
'black'"). The Supreme Court later reversed his conviction because
"the essential fairness required by the Due Process Clause of the
Fourteenth Amendment requires that under the facts shown by this
record [he] be permitted to have the jurors interrogated on the
issue of racial bias." Id. at 527.
     Dzhokhar notes that the state's brief there had argued that
the judge's general "bias or prejudice" question sufficed because
the defendant was "within sight" of the prospective jurors, who
could discern his race — which, according to the state, made the
specific questions about race redundant and thus unnecessary. See
Br. for Resp., Ham, 409 U.S. 524 (No. 71-5139), 1972 WL 135829, at
*3-4. And by Dzhokhar's account, the Supreme Court's reversal of
Ham's conviction "establishes that a [prospective juror's]
awareness of facts which could give rise to potential bias, coupled
with general questions about bias, do not obviate a particularized
investigation into prejudice." Extrapolating from this reading,
he argues that Ham shows the judge legally erred by deeming case-
specific questions about prospective jurors' death-penalty views
unnecessary because of what they already knew about the case. The
simplest response is that the Ham Court never addressed the state's
argument that a general question sufficed. So Ham does not help
his cause.   See generally Ristaino v. Ross, 424 U.S. 589, 596
(1976) (emphasizing that "[b]y its terms, Ham did not announce a
requirement of universal applicability").

                          Mitigation Evidence About
                     Tamerlan's Possible Homicidal Past

                We shift our focus to Dzhokhar's claim that the judge

damaged the defense's mitigation case by barring evidence tying

Tamerlan to a triple murder in 2011, and by keeping the defense

from seeing a confession Tamerlan's friend made to the FBI about

how he and Tamerlan had committed those crimes.

                                  Background

                On September 11, 2011 — the tenth anniversary of the

9/11 terrorist attacks — someone (or a number of someones) robbed

and   killed      three   drug   dealers   in   an   apartment   in   Waltham,

Massachusetts.        All three were found bound, with their throats

slit.        These crimes remain unsolved to this day.

                Fast forward to 2013.   Soon after the Marathon bombings,

federal and state law-enforcement officers interviewed Tamerlan's

friend, Ibragim Todashev — a mixed-martial-arts fighter who had

come to the United States from Chechnya in 2008 and met Tamerlan

shortly afterwards.35       Officers interviewed Todashev, then living

       Perhaps this is as good a place as any to say a few words
        35

about Dzhokhar's family background, as best we can discern it from
the record.
     Dzhokhar and Tamerlan's father, Anzor, is of Chechen ancestry
born in Kyrgyzstan. Their mother, Zubeidat, is of Avar ancestry
born in Dagestan. She and Anzor met as teenagers in Siberia in
the early 1980s — she was there living with her brother, and he
was stationed there with the Soviet Army. The two later married
and moved around a bit, living in Siberia, Chechnya, Dagestan, and
                              - 77 -
in Florida, four separate times in April and May.     The first two

interviews focused on his relationship with Tamerlan and his

possible knowledge of the bombings.     At some point, agents began

suspecting that Todashev had a hand in the 2011 murders.     During

the final interview on May 21, Todashev said he knew something

about the murders and asked if he could get a deal for cooperating.

           After waiving his Miranda rights, Todashev gave the

following account.    Tamerlan recruited Todashev to rob the men.

They drove to a Waltham apartment, held the men at gunpoint (with

a gun Tamerlan had brought), beat them, and bound them with duct

tape.   Not wanting to leave any witnesses, Tamerlan cut each man's

throat while Todashev waited outside (Todashev did not want any

part of the throat cutting, apparently).       Tamerlan then waved

Todashev back in to help remove all traces of evidence.

           Todashev agreed to write out a confession.     But as he

was doing so, he attacked the agents — one of whom shot and killed

him.    The FBI documented Todashev's statements in memos known as

302 reports.   And a state trooper recorded most of his statements

Kyrgyzstan (for example). During this time, they had four children
— including Tamerlan (in 1986) and Dzhokhar (in 1993).
     In 2002, with the region embroiled in a bloody war with
Russia, Anzor, Zubeidat, and Dzhokhar emigrated from Kyrgyzstan to
the United States — specifically, to Cambridge, Massachusetts.
Dzhokhar's other siblings joined them in 2003. Anzor and Zubeidat
returned to Russia in 2012, leaving Dzhokhar in the United States
with Tamerlan.
                               - 78 -
at his final interview.            The Florida attorney general's office

investigated the circumstances of Todashev's death and found the

agent had acted reasonably in using deadly force.

                Dzhokhar's lawyers repeatedly asked the judge pretrial

to make the government produce all reports and recordings of

Todashev's statements about the Waltham crimes, either directly to

them or to the judge for an in-camera inspection.36              The government

opposed each of the defense's motions, arguing that the sought-

after materials were not discoverable under the federal or local

criminal rules or under Brady v. Maryland, 373 U.S. 83 (1963), and

were protected by the law enforcement investigatory privilege.37

In the government's telling, because prosecutors had informed the

defense that Tamerlan had "participated in the Waltham triple

homicide," it did not have to disclose the actual reports and

recordings.        After inspecting some of the items in camera, the

judge        refused   to   disclose   any   of   the    materials   documenting

Todashev's        statements.      Agreeing       with   the   government   that

       In camera means "in a chamber."
        36                                         See In Camera, Black's Law
Dictionary (11th ed. 2019).
       Basically, this judge-devised doctrine sometimes keeps the
        37

government from having to turn over materials law enforcement has
for use in criminal investigations — "sometimes," however, is a
tip-off that the privilege is not absolute, since it can be
overridden in appropriate cases by a party's need for the
privileged items. See, e.g., Puerto Rico v. United States, 490
F.3d 50, 64 (1st Cir. 2007).
                                       - 79 -
prosecutors     had       "conveyed     the    fact    and   general    substance     of

Todashev's statements," the judge said that the FBI's 302 report

of Todashev's final interview did "not materially advance [the

mitigation]         theory   beyond     what    is     already    available      to   the

defense."           The   judge   also     said       that   disclosing   Todashev's

statements "risk[ed] revealing facts seemingly innocuous on their

face, such as times of day or sequences of events," that "would

have   a     real    potential     to    interfere       with    the   ongoing    state

investigation."

              While all this was going on, a lawyer representing

Dzhokhar's college friend Dias Kadyrbayev — who faced prosecution

for hiding Dzhokhar's backpack and computer — told the government

that   his    client      "may    be    able   to     provide"   some   information,

including that "Kadyrbayev learned in the fall of 2012 from

Dzhokhar . . . that Tamerlan . . . was involved in the Waltham

murders" and that "Dzhokhar . . . told Kadyrbayev that [Tamerlan]

'had committed jihad' in Waltham."                      The government disclosed

Kadyrbayev's lawyer's proffer to Dzhokhar's counsel.

              Anyway, because of the judge's rulings, the defense

never learned key details about the murders (as disclosed by

Todashev) — including:

      Tamerlan brought the "tools" he and Todashev used to commit

       the crimes (a gun, knives, duct tape, cleaning supplies).

                                         - 80 -
     Tamerlan and Todashev got into the apartment because Tamerlan

      knew one of the victims, Brendan Mess — Tamerlan and Mess

      were close childhood friends.

     Tamerlan had Todashev duct tape one of the victim's hands and

      feet.    And Tamerlan duct taped the others.

     Tamerlan beat Mess to try to get him to say where more money

      was in the apartment.

     Todashev had agreed with Tamerlan to rob the men.            But after

      they had bound and robbed them, Tamerlan decided to kill the

      men — a decision that made Todashev shake with nerves, because

      while he did not want to participate in the murders, he felt

      he "had to" since he "did not have a way out."

     Tamerlan slashed each man's throat.

     Tamerlan    gave   Todashev   $20,000   from   the   money   they   had

      stolen.38

              The government later moved in limine to bar Dzhokhar

from introducing any evidence about the Waltham murders at the

guilt or penalty phases.39      Among other theories, the government

       Following an order from us, authorized counsel got to review
      38

the in-camera materials for the first time.
       In limine means "at the outset" — "a motion . . . raised
      39

preliminarily, esp[ecially] because of an issue about the
admissibility of evidence believed by the movant to be
prejudicial."  See In-Limine, Black's Law Dictionary (11th ed.
2019).
                                    - 81 -
called Todashev's statements about Tamerlan's role "unreliable"

since he had an obvious motive to pin the murders on someone else

(what the government did not tell the judge, however, was that

agents had previously relied on Todashev's statements in applying

for   a   search   warrant     to   look    for   evidence    from    the    Waltham

homicides in Tamerlan's car).              The government also argued that,

apart from Todashev's statements, it had no "evidence that Todashev

and/or Tamerlan . . . actually participated in the Waltham triple

homicides."        The   government     further     claimed    that     Todashev's

statements    should     not   come   in    because   he     "cannot    be   cross-

examined," because he "obviously was not of sound mind" since he

attacked armed agents, and because admitting this evidence would

confuse the jurors by opening the door to "a great deal of

information having nothing to do with" Dzhokhar's crimes.                    And the

government claimed that "[t]here's no evidence that the defense

can point to anywhere, including . . . Todashev's own statement,

that Tamerlan . . . controlled him in any way."

            Dzhokhar's lawyers argued in opposition that evidence

showing    Tamerlan's     having      committed     the    crimes      was   highly

probative of the brothers' respective roles in the bombings and

was sufficiently reliable to be admitted under the evidentiary

standards applicable at the penalty phase.                   They also stressed

that whether to credit Todashev's statements was for the jury.

                                      - 82 -
             The judge orally granted the government's in-limine

motion, finding that "there simply is insufficient evidence to

describe what participation Tamerlan may have had" in the Waltham

murders.     From his check of the evidence — which "include[d] an

in-camera review of some Todashev 302s," but not the recordings of

the confession — the judge thought that "it [was] as plausible

. . . that Todashev was the bad guy and Tamerlan was the minor

actor."    So the judge concluded that the murder evidence "would be

confusing to the jury and a waste of time, . . . without any

probative value."

             Dzhokhar's mitigation theory portrayed him as influenced

by Tamerlan to take part in the Marathon bombings.              "[I]f not for

Tamerlan,"    said   his   lawyer   to   the    penalty-phase    jury,   "this

wouldn't have happened."       And the defense sought to prove several

mitigating factors about their relationship and their relative

culpability — including:

     Dzhokhar "acted under the influence of his older brother";

     "because of Tamerlan's age, size, aggressiveness, domineering

      personality, [and] privileged status in the family," Dzhokhar

      "was particularly susceptible to his . . . influence";

     "Dzhokhar['s]    .   .   .   brother     Tamerlan   planned,   led,   and

      directed the Marathon bombing[s]";

                                    - 83 -
     "Dzhokhar . . . would not have committed the crimes but for

      his older brother Tamerlan"; and

     "Tamerlan . . . became radicalized first, and then encouraged

      his younger brother to follow him."

Without the Waltham evidence, the defense supported its mitigation

theory with testimony like:

     Tamerlan became radicalized first, began proselytizing his

      views, and sent jihadi materials to Dzhokhar;

     the oldest brother in a Chechen family like the Tsarnaevs

      usually    receives   deference    (an   associate   professor     from

      Princeton University testified that "it's expected that the

      younger brothers will listen to the older brother");

     Tamerlan occasionally broke the rules of the gym he belonged

      to (he used other members' equipment without asking, for

      instance);

     Tamerlan    sometimes   got    argumentative    at   a   mosque    (for

      example, he twice called the Imam a "hypocrite");

     Tamerlan yelled at a store owner for selling halal turkey for

      Thanksgiving (halal is a term associated with Islamic dietary

      laws); and

     Tamerlan     once   might   have   physically   abused    his     then-

      girlfriend (he later married her).

                                    - 84 -
          Conversely, the government tried to convince the jury

that Dzhokhar should die because he and Tamerlan were equally

culpable in the bombings and that Tamerlan had played no role in

Dzhokhar's decision to participate.   During the penalty phase, the

government argued that the defense's mitigation evidence consisted

of little more than "testimony that Tamerlan was bossy."         The

government also described Tamerlan as a "handsome," "charming,"

"loud" guy who "sometimes lost his temper."      And the government

implored the jurors to "ask [themselves] if there's anything about

Tamerlan . . . that will explain . . .      how Dzhokhar . . . could

take a bomb, leave it behind a row of children, walk . . . down

the street, and detonate it." Insisting that no evidence supported

the notion that Tamerlan had "coerced or controlled" Dzhokhar, the

government labeled the brothers "a partnership of equals" and so

"bear the same moral culpability for what they did."

                    Basic Appellate Arguments

          Dzhokhar presents essentially two arguments about the

judge's handling of the Waltham evidence.    The first claim is that

the judge violated his right to present a complete mitigation

defense by keeping from the jury major proof of Tamerlan's brutal

past, his ability to enlist others in acts of extreme cruelty, and

thus his relative culpability — an error the government exploited

by distorting Tamerlan's character and suggesting no evidence

                             - 85 -
showed his influence over Dzhokhar.            The second claim is that the

judge violated his Brady rights by refusing to give the defense a

302 report and recordings of Todashev's confession — evidence that,

"if presented," would have shown "why Tamerlan was to be feared,

and his ability to influence others to commit horrific crimes."

             The government takes a different view of the matter.

According to the government, the Waltham evidence was not relevant

mitigation evidence because nothing suggests Tamerlan's alleged

commission of the Waltham crimes had any link to Dzhokhar's

commission of the crimes here.         And, says the government, even if

the Waltham evidence had some slight relevance, the judge rightly

excluded   it   because    the   risks    of    confusing    the    issues    and

misleading the jury outweighed any probative worth. The government

also thinks that any error by the judge was harmless beyond a

reasonable      doubt     because      "overwhelming[]"      evidence        (the

government's word) showed Dzhokhar willingly engaged in the crimes

charged    here.     Wrapping    up,     the    government   says    that    the

undisclosed "information was not discoverable under Brady" and

"was subject to the law enforcement privilege."

                                    Analysis

             We give abuse-of-discretion review to preserved disputes

over whether the judge wrongly excluded mitigating evidence at the

penalty phase, showing "great deference" to his balancing of the

                                     - 86 -
evidence's probative worth against its possible prejudice.            See

United States v. Sampson, 486 F.3d 13, 42 (1st Cir. 2007) ("Sampson

I").40    We   also   give   abuse-of-discretion   review   to   preserved

disputes over whether the judge wrongly kept Brady material from

the defense.    See United States v. Bulger, 816 F.3d 137, 153 (1st

Cir. 2016).

           With these preliminaries out of the way, we turn to

Dzhokhar's first claim: that the judge committed prejudicial error

by keeping the Waltham evidence from the jury at the penalty phase.

           Because it is "desirable for the jury to have as much

information before it as possible when it makes the sentencing

decision," the Supreme Court has for years said that if "the

evidence introduced and the arguments made . . . do not prejudice

a defendant, it is preferable not to impose restrictions."          Gregg

v. Georgia, 448 U.S. 153, 203-04 (1976).      So a defendant convicted

of capital crime has a constitutional right to put before the jury,

"as a mitigating factor, any aspect of [his] character or record

and any of the circumstances of the offense that [he] proffers as

     40Dzhokhar argues that we owe no deference because the judge
"reviewed only the summary 302 report prepared by the FBI" and not
"the video and audio recordings themselves." But the two cases he
cites do not help him, because the judges there — unlike the judge
here — denied discovery without reviewing any of the at-issue
materials. See United States v. Rosario-Peralta, 175 F.3d 48, 55
(1st Cir. 1999); United States v. Buford, 889 F.2d 1406, 1407 (5th
Cir. 1989).
                                  - 87 -
a basis for a sentence less than death."              Lockett v. Ohio, 438
U.S. 586, 604 (1978) (plurality opinion); see also Eddings v.

Oklahoma, 455 U.S. 104, 110 (1982) (adopting the rule announced by

the Lockett plurality).        Mitigating factors include aspects of

"the defendant's background, record, or character or any other

circumstance of the offense that mitigate against imposition of

the death sentence," see 18 U.S.C. § 3592(a)(8) — like, for

instance, information bearing on the extent and nature of each

defendant's role in the charged crime, see Green v. Georgia, 442
U.S. 95, 97 (1979) (finding a constitutional violation where the

judge excluded penalty-phase evidence showing a codefendant's

primary role).

           This   standard     is   broad,   reflecting     the   idea    "that

punishment should be directly related to the personal culpability

of the criminal defendant."         See Penry v. Lynaugh, 492 U.S. 302,

319 (1989), abrogated on other grounds by Atkins v. Virginia, 536
U.S. 304 (2002); see also Enmund v. Florida, 458 U.S. 782, 801

(1982)   (emphasizing   that    "punishment    must    be   tailored     to    [a

defendant's]   personal   responsibility      and   moral    guilt").         And

consistent with this lenient approach, mitigating information need

not be admissible under the rules of evidence to get in.                 See 18

U.S.C. § 3593(c).    All of which is why the normally low relevance

threshold in noncapital cases is lower still when it comes to

                                    - 88 -
mitigation     evidence    in    capital   cases:       Relevant   "mitigating

evidence" encompasses any "evidence which tends logically to prove

or disprove some fact or circumstance which a fact-finder could

reasonably deem to have mitigating value."               See Smith v. Texas,

543 U.S. 37, 44 (2004).         Once this modest "threshold . . . is met,"

the Constitution "'requires that the jury be able to consider and

give effect to' a capital defendant's mitigating evidence."                  See

Tennard v. Dretke, 542 U.S. 274, 285 (2004) (quoting Boyde v.

California, 494 U.S. 370, 377-78 (1990)); see also Green, 442 U.S.

at 97 (holding that a "mechanistic[]" use of the hearsay rule to

keep a capital defendant from introducing mitigating evidence at

sentencing in a capital case offends due process (quotation marks

omitted)).

              None of this is code for anything goes, however.          For a

judge   can    exclude    "information"     if   "its    probative   value    is

outweighed by the danger of creating unfair prejudice, confusing

the issues, or misleading the jury."          See 18 U.S.C. § 3593(c); see

also Sampson I, 486 F.3d at 45 (stating that the "low barriers to

admission of evidence in a capital sentencing hearing 'do[] not

mean that the defense has carte blanche to introduce any and all

evidence that it wishes'" (quoting United States v. Purkey, 428
F.3d 738, 756 (8th Cir. 2005))).

                                     - 89 -
                The government in our case recognized that Dzhokhar's

penalty-phase defense turned on what Tamerlan's role was.                       Which

probably explains why in its own penalty-phase arguments, the

government continually called the brothers equally culpable and

stressed Tamerlan's lack of influence over Dzhokhar.                       The jurors

cared about the brothers' relative culpability as well, a point

made quite clear by their not recommending death for Dzhokhar on

the capital counts involving Tamerlan's conduct in setting off the

first        bomb.    And   given    how    the     proceedings   played     out,   the

probative value of showing that the bombings were not the first

time Tamerlan committed acts of brutality and persuaded others to

help him is obvious.            So we cannot agree with the judge that the

Waltham evidence lacks (emphasis ours) "any" probative force.

                Inspired by his jihadi beliefs, Tamerlan's lead role in

the   Waltham        killings    —   felonies       (according    to   the   kept-out

evidence) that he committed without Dzhokhar — makes it reasonably

more likely that he played a greater role in the crimes charged

here than Dzhokhar.41 And as we said a moment ago, evidence showing

a defendant's minor role in the offense is relevant mitigating

evidence under the rule broadcast in Lockett.                      See Enmund, 458
U.S. at 797-98.

        As Dzhokhar tells us in his reply brief, the government
        41

never suggests that Tamerlan did not commit the killings.
                                           - 90 -
             But there is more to be said in Dzhokhar's favor than

that.

             The    Waltham   evidence     was    also     highly   probative     of

Tamerlan's ability to influence Dzhokhar.                Because of the judge's

decisions, Dzhokhar did not present proof showing how he learned

(months after the fact, per college-acquaintance Kadyrbayev) that

Tamerlan had butchered the men, one of whom was a close friend —

actions motivated by Tamerlan's vision of jihad.42                  But evidence

of this sort could reasonably have persuaded at least one juror

that Dzhokhar did what he did because he feared what his brother

might do to him if he refused (and remember, a jury may consider

any   mitigating     factor   at   least    one    juror    found   proved   by   a

preponderance of the information).               Or put slightly differently,

at least one juror could reasonably have found that because of

what had happened in Waltham, Tamerlan was not just "bossy" (to

use the prosecutor's word) but a stone-cold killer who got a friend

to support his fiendish work.            And if Tamerlan could influence

Todashev     (a    mixed-martial-arts      bruiser    who    followed   Tamerlan

because he "did not have a way out"), Tamerlan's influence over

Dzhokhar (his younger brother with no prior history of violence)

        Defense counsel told us at oral argument that once the
        42

judge granted the government's in-limine motion barring any
mention of the Waltham crimes, Dzhokhar had no basis for trying to
get his statements to Kadyrbayev admitted.
                                    - 91 -
could        be   even     stronger.43     All     of   which    strengthens       two    of

Dzhokhar's mitigating factors — his susceptibility to Tamerlan's

influence, and his having acted under Tamerlan's influence.

                  And despite its hard work, the government's responses do

not persuade us otherwise.

                  The    government's     lead    argument      is   that    the   Waltham

evidence          cannot    clear   the   low     relevancy     hurdle      because   that

evidence (at least in its mind) would have told the jurors nothing

about the brothers' relative culpability here.                        Not so.      Again,

Dzhokhar premised his mitigation theory on his being less culpable

than Tamerlan because he would not have committed the charged

crimes but for Tamerlan's influence.                       And Tamerlan's earlier

domineering and deadly acts had relevance to this theory.                                The

judge admitted other, lesser evidence of Tamerlan's belligerence

— like his screaming at others for not conforming to his view of

how a good Muslim should act.                    And the judge did so because he

deemed that evidence relevant to Tamerlan's "domination."                             Even

this limited evidence convinced some jurors to find the existence

       Of course, when the government told the judge that he should
        43

bar the materials because "[t]here's no evidence that the defense
can point to anywhere, including . . . Todashev's own statement,
that Tamerlan . . . controlled him in any way," the defense did
not have Todashev's statement — including his telling comment that
he felt he "had to" help Tamerlan with the murder clean up because
he "did not have a way out."
                                           - 92 -
of mitigating factors touching on Tamerlan's prior radicalization,

leadership role in the bombings, and influence over Dzhokhar.   And

if Tamerlan's yelling at someone for selling halal turkeys had the

effect of showing his dominance and radicalization, then evidence

of his having conscripted a friend into a jihad-inspired robbery

and killing scheme would have increased that effect exponentially.

            The government is wrong to imply that the jury had to

make leaps of imagination to connect what Tamerlan did in Waltham

to his influence over Dzhokhar.    If the judge had admitted this

evidence, the jurors would have learned that Dzhokhar knew by the

fall of 2012 that Tamerlan had killed the drug dealers in the name

of jihad.   They also would have known that it was only after these

killings that Dzhokhar became radicalized as well:        Evidence

actually admitted showed that Dzhokhar first flashed signs of

radicalization — as is obvious from his texts on jihad — after

spending a holiday break with Tamerlan several weeks or so after

learning about the Waltham murders.44   So if the jurors had heard

Todashev's description of how he felt powerless to withdraw from

the Waltham crimes once Tamerlan chose to turn an armed robbery

into a triple murder, at least one juror might have found that

     44 For example, texting with someone (a friend, presumably)
about life plans, Dzhokhar wrote: "I wanna bring justice for my
people."
                               - 93 -
Dzhokhar felt the same way when it came to the bombings in early

2013.

             And if the judge had admitted the Waltham evidence —

evidence that shows (like no other) that Tamerlan was predisposed

to religiously-inspired brutality before the bombings and before

Dzhokhar's     radicalization45   —   the   defense     could   have   more

forcefully rebutted the government's claim that the brothers had

a "partnership of equals."    The Waltham evidence would have helped

the defense show that Tamerlan inspired his younger brother not

only to believe in jihad but also to act on those beliefs — just

as he had in Waltham (again, the government does not suggest that

Tamerlan did not commit the murders).          Similarly, the evidence

could have helped the defense counter the government's argument

that Tamerlan and Dzhokhar "bear the same moral culpability" and

that Dzhokhar acted "independently" in placing the bomb at the

finish line — for the evidence showed that Tamerlan, unlike

Dzhokhar, had a history of horrific violence, which he justified

as   jihad;    that   Tamerlan,   unlike    Dzhokhar,     had   previously

instigated, planned, and led brutal attacks; and that Tamerlan,

unlike Dzhokhar, had influenced a less culpable person (Todashev)

to participate in murder.

       Think back to how the Waltham murders occurred on the decade
        45

anniversary of the 9/11 attacks.
                                  - 94 -
           The government still could have argued to the jurors —

as it does to us — that Dzhokhar was nevertheless a willing

criminal. The government also could have challenged the evidence's

reliability, arguing that other than his self-serving statement

about thinking he "had to" help clean up the scene, nothing proves

Tamerlan bullied Todashev into doing anything.      See 18 U.S.C.

§ 3593(c) (providing that either party can rebut any information

received at the hearing).    And maybe the government could have

argued that the evidence undercuts Dzhokhar's mitigation theory —

saying something like, Tamerlan had to pay Todashev money to get

him to go along, while Dzhokhar joined on for free; and Todashev

opted not to kill, while Dzhokhar killed with no reluctance or

regret.   But all of this goes to weight and credibility and not to

admissibility — i.e., the effect of Tamerlan's prior violence on

Dzhokhar's radicalization, on his willingness to go from texting

to bombing, was something the jurors should have gotten to decide

for themselves.   See, e.g., United States v. Guzmán-Montañez, 756
F.3d 1, 9 (1st Cir. 2014) (explaining that "[w]hen the issue lies

on credibility of the evidence, it is up to the jury to decide"

and adding that "[t]he factfinder is free to conduct its own

interpretation of the evidence"); Nelson v. Quarterman, 472 F.3d
- 95 -
287, 313 (5th Cir. 2006) (en banc) (noting that the "strength" or

"sufficiency" of mitigating evidence is for the jury to decide).46

           The government insists that because the circumstances of

the Waltham killings are too dissimilar to the bombings, the

Waltham evidence has no relevance here.       But in both situations,

Tamerlan committed murder with help from someone who gave no prior

sign of a willingness to commit such acts. And in both situations,

Tamerlan used his interpretations of Islam to justify his actions.

So the government's too-dissimilar argument has no merit either.

           Shifting from the relevancy question, the government

defends   the   judge's   actions   by   insisting   that   the   Waltham

evidence's admission would have led to mini-trials over whether

Todashev's version of the killings "was believable" or just a pack

of lies told to minimize his responsibility for those crimes.        But

the concern is overblown.     As Dzhokhar notes, the defense could

have relied, for instance, on the government's sworn search-

warrant materials (to search Tamerlan's car after the bombings)

     46  The   government   does   not  argue   that   Todashev's
unavailability precludes admission in the penalty-phase context —
perhaps because of the relaxed evidentiary standards.     And the
judge permitted the statements of other unavailable witnesses at
the penalty phase — including FBI 302 reports summarizing
interviews of some of Tamerlan's friends.

                                - 96 -
that credited Todashev's statements to the FBI.47   The government

now tries to soft-pedal its crediting of Todashev's account in the

search-warrant affidavit as "a far cry from embracing those claims"

at trial.   But when the agent swore out the affidavit and the

prosecutor submitted the materials to the magistrate judge, the

government confirmed its belief in Todashev's veracity.         See

     47An FBI agent swore out an affidavit saying that "there is
probable cause to believe that Todashev and Tamerlan planned and
carried out the murder of three individuals in Waltham . . . in
September 2011." "On May 21, 2013," the affidavit stated,
     law enforcement agents interviewed Todashev. Todashev
     confessed that he and Tamerlan participated in the
     Waltham murders. He said that he and Tamerlan had agreed
     initially just to rob the victims, whom they knew to be
     drug dealers . . . . Todashev said that he and Tamerlan
     took several thousand dollars from the residence and
     split the money. Todashev said that Tamerlan had a gun,
     which he brandished to enter the residence.
The affidavit further said that
     Tamerlan decided that they should eliminate any
     witnesses to the crime, and then Todashev and Tamerlan
     bound the victims, who were ultimately murdered.
     Todashev went on to say that after the murders, Tamerlan
     and Todashev tried to clean the crime scene . . . to
     remove   traces   of  their   fingerprints   and   other
     identifying details. . . .       [T]o clean the scene,
     Todashev said that they used bleach and other chemicals
     to clean surfaces, and even poured some on the bodies of
     the victims. Todashev said that they spent over an hour
     cleaning the scene.
And the affidavit also noted that
     Todashev said that Tamerlan had picked Todashev up in
     the Target Vehicle and they traveled to the scene of the
     Waltham murders together. After the robbery and murder,
     they left the scene in the Target Vehicle.
                              - 97 -
generally   Franks     v.    Delaware,     438 U.S. 154,   164-65      (1978)

(explaining that "[w]hen the Fourth Amendment demands a factual

showing   sufficient    to     comprise    'probable      cause,'    the    obvious

assumption is that there will be a truthful showing," and adding

that "it is to be 'truthful' in the sense that the information put

forth is believed or appropriately accepted by the affiant as

true").   We know of no reason why the sworn affidavit — which the

government asked the magistrate judge to credit — should now be

disbelieved.   To this we add that the judge retained control over

how much of this evidence could have come in.               He also could have

limited the evidence as appropriate or cut off the presentation if

the evidence became too extensive — a more suitable remedy than

barring all evidence of Tamerlan's murderous past.                  So in the end

we think the Waltham evidence was sufficiently reliable to go to

the jurors, who could then decide whether to believe it and how

much weight (if any) to assign it in mitigation.                     See Guzmán-

Montañez, 756 F.3d at 9.

            The government is also off-base in saying that "[t]he

Waltham   evidence     would    have     confusingly      focused     the    jury's

attention on Tamerlan's character and the circumstances of an

unrelated   offense."        But   the    parties   and    the   judge      put   the

mitigating factors before the jury, front and center — factors

that made clear that Tamerlan's character and prior conduct were

                                    - 98 -
relevant    because   they   bore   on   the   broader   circumstances   of

Dzhokhar's commission of the charged crimes.48             Arguing to the

jury, the government called Dzhokhar's mitigation theory (centered

on Tamerlan's influence over him) baseless because no evidence

supported it.     But the Waltham evidence could have been that

evidence.     And it would not have confused the jurors to have

learned about it.     Caselaw tells us to presume that juries follow

instructions.    See, e.g., Richardson v. Marsh, 481 U.S. 200, 211

(1987).    And the jurors' penalty-phase verdicts — not recommending

death on 11 of the 17 death-eligible counts — show they fully

understood that Tamerlan's relative culpability was mitigating

only to the extent it bore on the brothers' respective roles in

committing the charged crimes.49         Which compels us to reject the

government's claim that the jurors would have lost sight of this

distinction.

     48We are referring here to the mitigating factors mentioned
in the second bullet-point list above, which required the jurors
to resolve a set of "whethers": whether Dzhokhar acted under the
influence of Tamerlan; whether Tamerlan's aggressiveness made
Dzhokhar susceptible to following his lead; whether Tamerlan
instigated and led the bombings; whether Dzhokhar would ever have
committed these crimes were it not for Tamerlan; and whether
Tamerlan radicalized first and encouraged Dzhokhar to follow him.
     49 The jury, for example, recommended death on those counts
dealing with Dzhokhar's placing a bomb (the zenith of Dzhokhar's
responsibility) but did not recommend death on those counts dealing
with Tamerlan's placing a bomb (the nadir of Dzhokhar's
responsibility).
                                    - 99 -
            So we find the judge abused his discretion in banning

the Waltham evidence.        Compare McKinney v. Arizona, 140 S. Ct.
702, 706 (2020) (stressing "that a capital sentencer may not refuse

as a matter of law to consider relevant mitigating evidence"),

with United States v. Rodriguez, 919 F.3d 629, 634 (1st Cir. 2019)

(explaining "that a material error of law always amounts to an

abuse of discretion").       The government thinks that any error was

harmless    beyond   a   reasonable   doubt.50      But   the   government's

harmlessness claim is essentially a reprise of its argument in

support of exclusion:      In its view, just as the Waltham evidence

is irrelevant because it does not show that Dzhokhar participated

in the bombings under Tamerlan's influence, for the same reasons,

its exclusion could not have affected the jurors' decision. Again,

though,    the   exclusion    of    the   Waltham    evidence    undermined

Dzhokhar's mitigation case.         Sure, as the government argues, a

jury armed with the omitted evidence still might have recommended

death.     But the omitted evidence might have tipped at least one

juror's decisional scale away from death.            In other words, the

government cannot show to a "near certitude," see Victor, 511 U.S.
50The parties spar a bit over whether a judge's mistake in
banning mitigating evidence is subject to harmless-error review.
Dzhokhar argues it is not; the government argues it is. We need
not get into that here: Even under its preferred approach, the
government cannot win because (as we are about to explain) the
government cannot satisfy its harmlessness burden.
                                   - 100 -
at 15, that the excluded evidence — that Tamerlan cold-bloodedly

killed the drug dealers, all in the name of jihad — would not have

convinced even one juror that (contrary to the government's jury

argument) Dzhokhar did not "bear the same moral culpability" as

Tamerlan, see Skipper v. South Carolina, 476 U.S. 1, 8 (1986)

(holding that because the judge's ruling excluding mitigating

evidence "may have affected the jury's decision to impose the death

sentence," the error was "sufficiently prejudicial" to require

vacatur of the defendant's death sentence).

          This    leaves    us     then     with   Dzhokhar's      Brady-based

challenge: that the judge also erred by denying the defense access

to additional evidence both favorable and material to him —

specifically,    the   report     and     recordings   of    Todashev's     FBI

confession.

          Prosecutors have an "inescapable" duty "to disclose

known,   favorable     evidence    rising     to   a   material     level    of

importance."      Kyles    v.    Whitley,    514 U.S. 419,   438   (1995)

(discussing Brady).     Favorable evidence includes both exculpatory

and impeachment evidence that is relevant either to guilt or

punishment.     See, e.g., United States v. Bagley, 473 U.S. 667,

674-76 (1985); Giglio v. United States, 405 U.S. 150, 154 (1972).

Material evidence includes information that creates a "reasonable

probability" of a different outcome, see Kyles, 514 U.S. at 433 —

                                   - 101 -
and in a capital case that encompasses data that "play[s] a

mitigating, though not exculpating, role," see Cone v. Bell, 556
U.S. 449, 475 (2009).        But make no mistake:     "A reasonable

probability does not mean that the defendant 'would more likely

than not have [gotten] a different [result] with the evidence,'

only that the likelihood of a different result is great enough to

'undermine[ ] confidence'" in the proceeding's outcome.    See Smith

v. Cain, 565 U.S. 73, 75 (2012) (last alteration in original)

(quoting Kyles, 514 U.S. at 434).     To find the withheld evidence

not material, the judge must conclude that the other evidence is

so overwhelming that, even if the undisclosed evidence had gotten

in, there would be no "reasonable probability" of a different

result.   And this standard is not met just because the government

"offers a reason that the jury could have disbelieved [the withheld

evidence], but gives us no confidence that it would have done so."
Id. at 76.

             Several pages earlier we noted how the judge ruled that

the government had already given the defense the gist of Todashev's

statements and so the sought-after material did "not materially

advance [the mitigation] theory beyond what is already available

to the defense."      But as we also explained, that material had

information that the defense never saw below, including:       that

Tamerlan planned the Waltham crime, got Todashev to join in, and

                                - 102 -
brought the key materials (gun, knives, duct tape, and cleaning

supplies) to the apartment; that Tamerlan thought up the idea of

killing the three men to cover up the robbery; and that Todashev

felt "he did not have a way out" from doing what Tamerlan wanted.

Todashev's    confession      showed    —    probably   more   than    any   other

evidence — how and why Tamerlan inspired fear and influenced

another to commit unspeakable crimes and thus strongly supported

the defense's arguments about relative culpability.                    And armed

with these withheld details, the defense could have investigated

further and developed additional mitigating evidence.                 To us, this

means   there    is    a   reasonable    probability    that    the   material's

disclosure would have produced a different penalty-phase result.

So the confession constituted Brady material, making it reversible

error for the judge to rule the evidence off-limits from discovery.

             And we find that the judge also erred by relying on the

qualified law enforcement investigatory privilege.                As the party

asserting the privilege, the government had the burden of showing

that withholding the FBI report and recordings would achieve the

privilege's "underlying purpose" of not jeopardizing an ongoing

investigation.        See Puerto Rico, 490 F.3d at 62-64 (recognizing "a

qualified       privilege     for      law    enforcement      techniques      and

procedures").         The showing must be specific not speculative,

concrete not conclusory.            See id. at 62.        But the government

                                     - 103 -
offered no specific ways in which disclosure would have endangered

the   ongoing      Waltham-murders     investigation   —     particularly    if

disclosure occurred under a protective order.                 See Ass'n for

Reduction of Violence v. Hall, 734 F.2d 63, 66 (1st Cir. 1984)

(emphasizing that where possible, a court should accommodate a

moving party's interest in disclosure through excising privileged

sections, editing or summarizing documents, or okaying discovery

subject to a protective order).            The Waltham murders occurred in

2011.        By 2015, when Dzhokhar's penalty phase began, the only

identified suspects — Tamerlan and Todashev — were both dead.               And

the government did not ask the district attorney's office to

explain        whether   and   why   the   privilege   was    still   viable.

Ultimately,        the   judge's     speculation   about     how   disclosing

Todashev's statements might compromise the investigation was just

that:        speculation.   Which as we just observed is not sufficient.

               The long and the short of it is that the judge's handling

of the Waltham evidence provides an additional basis for vacating

Dzhokhar's death sentences.51

infracted    his     constitutional    right     against   compelled       self-

incrimination and the criminal rules of procedure by conditioning

the admission of his "non-testimonial neuropsychological evidence"

on   his   "be[ing]    interrogated,    without    limits,     by    government

experts."

            A death-penalty defendant wishing to make an issue of

his mental health and present expert evidence on that subject must

notify the government within specified time limits.                 See Fed. R.

Crim. P. 12.2(b).      If he does that, the judge may order a rebuttal

exam by the government's expert "under procedures ordered by the

[judge]."     See Fed. R. Crim. P. 12.2(c)(1)(B).               Judges often

appoint assistant U.S. attorneys from another district as "fire-

walled" attorneys to handle this process. See, e.g., United States

v. Sampson, 335 F. Supp. 2d 166, 244-45 (D. Mass. 2004).                      The

results and reports from a rebuttal exam must be sealed and not

given to the prosecution or the defense unless the defendant is

found guilty and confirms his intent to rely on mental-condition

evidence    during     the   penalty   phase.     See   Fed.    R.    Crim.    P.

12.2(c)(2).       If this happens, the defendant must then give the

government any results and reports of his mental condition "about

which [he] intends to introduce expert evidence."                See Fed. R.

Crim. P. 12.2(c)(3).       But prosecutors cannot use any statement he

made during an exam conducted under this regime unless he first

introduces evidence of his mental condition, see Fed. R. Crim. P.

12.2(c)(4) — a rule designed to protect a defendant's Fifth

Amendment privilege against compulsory self-incrimination,52 see

Fed. R. Crim. P. 12.2 advisory committee notes. See also generally

Estelle v. Smith, 451 U.S. 454, 466-69 (1981) (recognizing that a

psychiatrist's court-ordered competency exam in a capital case

raised the same Fifth (and Sixth) Amendment concerns as an in-

custody interrogation by law enforcement); Buchanan v. Kentucky,

483 U.S. 402, 424 (1987) (explaining that if a defendant tries to

establish     a     mental-status       defense,    the     government   may

constitutionally force him to submit to an interview with a mental-

health expert for "limited rebuttal purpose[s]").

            Citing Criminal Rule 12.2, Dzhokhar's lawyers filed a

pretrial notice of intent to introduce expert evidence about "his

mental    condition   as   it   bears    on   the   issue   of   punishment."

case to be a witness against himself." U.S. Const. amend. V.

Simultaneously, they told the prosecution that they planned on

presenting "neuropsychological testimony" that would rely on the

results of various tests done on Dzhokhar (an intelligence test,

for example).      The judge created a separate sealed docket and

appointed    two    fire-walled    assistant   U.S.   attorneys    from

Connecticut and New York to manage the government's rebuttal exams

and to represent the government in any related litigation.        In an

ex-parte proffer to the judge, Dzhokhar's attorneys claimed that

the neuropsychological and neuroimaging exams revealed information

that would support his mitigation theory.53

            Through the fire-walled attorneys, the government told

the defense that it intended to have two experts examine Dzhokhar.

The first would do a clinical interview of him and administer some

tests (the just-mentioned intelligence test being one of them).

The second would do a psychiatric exam focusing on his "life

choices," especially "those decisions and actions underlying the

charged criminal conduct," while also "explor[ing] the effects, if

any of [his] social history, personality, mental state, social

     53Ex parte is a Latin phrase basically meaning only one side
is heard — "[d]one or made at the instance and for the benefit of
one party only, and without notice to, or argument by, anyone
having an adverse interest." See Ex Parte, Black's Law Dictionary

environment, family influences, peer pressure, and any duress to

which [he] may have been subjected."54

            The   defense    objected   to   the   government's   notice.

Insisting that prosecutors have "only a limited rebuttal right,"

the defense asked the judge to limit the exams of the government

experts to "the same type of testing conducted by the defense

experts" — i.e., "objective" tests, like the "computer based

tests," "pen and paper tests," "physical tests," and "neuroimaging

test[s]" that the defense experts used.         None of these tests, the

defense argued, would elicit or rely on statements by Dzhokhar

expressing his views about his own symptoms or history.               So

according to the defense, the judge had to bar the government

experts from "asking questions beyond those specified in the test

instruments themselves, or otherwise engaging [Dzhokhar] in any

communication intended to elicit testimonial evidence, including[]

opinions, view[s], beliefs, historical information or anything

else."    That is because asking such questions would "compel him to

testify against himself," or so the defense contended.

            Responding,     the   fire-walled   attorneys   argued   that

Dzhokhar could not "dictate and limit" their experts' "testing by

undergo some brain-imaging scans, with a third doctor then
analyzing the results. But the defense has not complained about
this proposed testing, either below or here.
                                  - 108 -
selecting certain tests and then objecting to different tests that

inform the subject matter under inquiry."              Dzhokhar, they noted,

had not revealed exactly "what type of mental disease or defect

defense he is intending to assert" — though they suspected he would

"claim that he was particularly susceptible to his brother's

persuasion" based on "a dependent personality disorder."                And they

insisted that the government's proposed exams would rebut that

claim by showing he could think independently.                Admittedly, some

of the information the experts got might not be admissible, they

said — but they insisted that "curtailing the government's right

to prepare at this juncture d[id] nothing more than allow the

defendant to present completely un-contradicted testimony."

             After   a   hearing,     the     judge    overruled      Dzhokhar's

objection.    Rule 12.2 did not "limit[] the rebuttal to simply the

same . . . tests or investigations" that the defense performed,

the judge said.       "[A]n appropriate rebuttal," the judge pointed

out, might be "to say that the wrong tests were done or that

insufficient tests were done."        The judge did not want to prevent

the   government     experts   from   using    tests   that    they    in   their

"professional judgment" deemed "appropriate."             But the judge made

clear that his ruling did not "mean necessarily" that the exams'

results would be "admissible" or "usable" at trial — it all

depended on what the "defense present[ed]."              Attempting one last

                                    - 109 -
stand,     defense   counsel   argued   that    "we   are   offering   nothing

testimonial from [Dzhokhar]," just "the results of pen-and-paper

tests."     So the defense asked the judge to "make the rebuttal call

now   as   opposed   to   exposing   [him]     to   an   interrogation   by   a

government agent, essentially."         But the judge remained unmoved.

"I don't think I can make it until I know what the exam[s] might

reveal and what [any government expert] might be offered to say."

Consequently, the exams could go forward, even though they "may

not produce admissible evidence" — an approach that he said posed

no constitutional problems.

             After the ruling (but before the government experts

could examine him), Dzhokhar withdrew his Rule 12.2 notice.              "The

broad scope" of the planned exams, his lawyers wrote, "without the

presence of counsel," plus "the use the [judge] indicated can be

made" of the exams' results, violate Dzhokhar's constitutional

rights and clash with Rule 12.2.               As the defense saw things,

"[t]hese conditions separately and cumulatively impose too great

a cost on the introduction of [his] proposed [mental-health]

evidence."

                                  - 110 -
                    Basic Appellate Arguments

          Broadly speaking, Dzhokhar claims that the judge created

a "constitutional mismatch."     In his telling, the results of the

testing he planned to introduce were not testimonial in any

constitutional sense.   During his test-taking — which he calls a

"pen and paper" exercise, like having his "reflexes" evaluated —

he neither offered his beliefs or thoughts on "historical or life

events," nor talked about "the crimes charged against him[] or his

family background." Contrastingly — at least according to Dzhokhar

— and "as the price of" admitting his "non-speech" mental-health

evidence, the judge essentially ruled that the government experts

could interrogate him on a wide range of topics, including "the

charged criminal conduct."     And, the argument goes, by setting

this price, the judge forced him to withdraw his notice, damaging

his mitigation case — which violated his rights both under the

Fifth Amendment and Rule 12.2.

          The government counters with several arguments.     Among

other things, the government contends — citing Luce v. United

States, 469 U.S. 38 (1984) — that by withdrawing his Rule 12.2

notice and not presenting his mental-health evidence, Dzhokhar

failed to preserve this issue for appeal.   Preservation aside, the

government claims that he cannot show that the Fifth Amendment

privilege — which protects against real rather than speculative

                               - 111 -
dangers — actually applied here.        The judge did not order him to

submit to any mental-health exams, the government notes, and

prosecutors did not comment on his failure to introduce mental-

condition evidence — which makes this situation the direct opposite

of   compulsory.     Also,   the   government    reminds   us,     the   judge

repeatedly said that he would not necessarily admit the results of

the government experts' exams.        And, the argument proceeds, even

if the judge did admit the exam results, prosecutors could only

use them for rebuttal purposes — which the government says is

perfectly permissible under Kansas v. Cheever, 571 U.S. 87, 94, 98

(2013).   Additionally, to quote again from the government's brief,

Dzhokhar's mental-health evidence "would have had little or no

mitigating    effect,"   because    other    evidence   rebutted    what   the

government surmises was his mitigation defense (the government

highlights testimony about his academic achievements, like his

getting mostly A's in middle school).

             Pertinently for our purposes, Dzhokhar's reply contests

the government's preservation point.         As he sees things, a pair of

Supreme Court cases — Brooks v. Tennessee, 406 U.S. 605 (1972),

and New Jersey v. Portash, 440 U.S. 450 (1979) — allows a defendant

to challenge on appeal obstacles that "'reach[] constitutional

dimensions' without first taking the stand," which he argues is

the situation here.

                                   - 112 -
                             Analysis

           The parties note that different standards of review may

come into play here:   for instance, fresh-eyed review ("de novo,"

in legal parlance) for claims involving the judge's interpretation

of the protections provided by privilege against forced self-

incrimination, see Amato v. United States, 450 F.3d 46, 49 (1st

Cir. 2006), but abuse-of-discretion review for claims about the

exclusion of testimony under Rule 12.2, see United States v.

Cartagena-Carrasquillo, 70 F.3d 706, 710 (1st Cir. 1995), and for

claims concerning the scope of rebuttal testimony, see United

States v. Sebaggala, 256 F.3d 59, 66 (1st Cir. 2001).

           Often "[t]he simplest way" to decide an issue is "the

best."   See Stor/Gard, Inc. v. Strathmore Ins. Co., 717 F.3d 242,

248 (1st Cir. 2013) (quoting Chambers v. Bowersox, 157 F.3d 560,

564 n.4 (8th Cir. 1998) (R. Arnold, J.)).   And that is so here.

           Skipping over the parties' preservation points (which

lets us avoid having to work through a complex series of arguments

and cases), we conclude that Dzhokhar's reliance on the Fifth

Amendment privilege fails.   To get anywhere, he must show that he

had "reasonable cause to apprehend danger" from submitting to

interviews with the government experts, see Hoffman v. United

States, 341 U.S. 479, 486 (1951) — for as the Supreme Court has

long emphasized, "the privilege protects against real dangers, not

                              - 113 -
remote and speculative possibilities," see Zicarelli v. N.J. State

Comm'n of Investigation, 406 U.S. 472, 478 (1972).           But the judge

here said over and over again that he would not automatically admit

the results of the government experts' exams, and that even if he

did admit them, prosecutors could use them only for "rebuttal" —

which is copacetic under the Fifth Amendment.          See Cheever, 571
U.S. at 94, 98.      So no appreciable danger of a Fifth Amendment

violation   would    have   arisen   unless   (1) Dzhokhar    incriminated

himself during the government experts' exams, (2) he still chose

to present mental-health evidence, (3) the judge let a government

expert testify based on Dzhokhar's self-incriminating comments,

and (4) the expert's testimony was not proper rebuttal.          To ask us

to find this rank conjecture sufficient (as Dzhokhar does) is

asking too much.      See Minor v. United States, 396 U.S. 87, 98

(1969) (explaining that one must show "'real and appreciable' risks

to support a Fifth Amendment claim").

            On then to another issue.

                     Surviving Victims' Testimony

            In this section we tackle Dzhokhar's claim that the judge

erred by admitting "victim impact" testimony by survivors at the

penalty phase.      As briefed here, his challenge is factually and

                                 - 114 -
legally intricate.         But because there is a straightforward route

to resolving it, we can streamline and simplify our discussion.

            The FDPA says that when the government seeks a death

sentence, it must "serve on the defendant[] a notice . . . setting

forth the aggravating factor or factors" it believes justify the

death   penalty.      18    U.S.C.   §   3593(a).         In   its   notice   here,

prosecutors     specified       several     statutory          aggravators    they

envisioned proving in pursuing the death penalty against Dzhokhar

— including:

     his "knowingly creat[ing] a grave risk of death to 1 or more

      persons in addition to" the victims who died, see 18 U.S.C.

      § 3592(c)(5);

     his   "committ[ing]      the   offense    in   an    especially      heinous,

      cruel,   and   depraved    manner    in   that      it    involved   serious

      physical abuse to the victim," see id. § 3592(c)(6); and

     his "committ[ing] the offense after substantial planning and

      premeditation to cause the death of a person and commit an

      act of terrorism," see id. § 3592(c)(9).

The notice also listed several nonstatutory aggravators, see id.

§ 3593(a)(2) — including:

     his "target[ing] the Boston Marathon, an iconic event that

      draws large crowds of men, women[,] and children to its final

                                     - 115 -
      stretch, making it especially susceptible to the act and

      effects of terrorism"; and

     his    "participat[ing]    in    additional    uncharged     crimes   of

      violence," like "assault with intent to maim, mayhem[,] and

      attempted murder."

             Dzhokhar's   appellate     argument    only   focuses    on    the

victim-impact aggravator.       And it proceeds in four steps:        (1) He

notes (emphasis ours) that § 3593(a)(2) provides that nonstatutory

aggravators

      may include factors concerning the effect of the offense
      on the victim and the victim's family, and may include
      oral   testimony,   a   victim impact   statement   that
      identifies the victim of the offense and the extent and
      scope of the injury and loss suffered by the victim and
      the victim's family, and any other relevant information.

(2) He then says that the reference to the "victim and the victim's

family"     precludes   penalty-phase    testimony    on   "the    impact   of

survivors'     injuries   on   those    survivors    (or   their   families)

themselves."     (3) That is so, he contends, because even though

this FDPA subsection does not define "victim," Congress used

"victim" in three other subsections and in the Act's legislative

history to refer to a "victim" who died.55           And (4) asking us to

      55The provisions he cites are:     18 U.S.C. § 3591(a)(2)
(referring to offenses where the defendant "killed the victim,"
offenses that "resulted in the death of the victim," and offenses
where the "victim died"); 18 U.S.C. § 3592(a)(7) (listing as a
mitigating factor the fact that the victim "consented to the
criminal conduct that resulted in the victim's death"); and 18
                             - 116 -
apply the usual rule of statutory interpretation that identical

words bear identical meaning throughout the same act, he believes

that such an analysis should lead us to conclude that the judge

misinterpreted the statute to allow "victim impact evidence from

surviving victims at the penalty phase."

          If    preserved,   we   review    challenges    to   the   judge's

interpretation of the FDPA afresh (i.e., de novo), see United

States v. Troy, 618 F.3d 27, 35 (1st Cir. 2010), and challenges to

his   rulings   admitting    or   excluding    evidence     for   abuse   of

discretion, see Sampson I, 486 F.3d at 42.               Dzhokhar says he

preserved his challenges at trial; the government says he did not

and so must now prove plain error on the judge's part.            A famously

demanding standard, plain error requires the proponent to show not

just error, but error that is plain, that affects his substantial

rights, and that seriously impaired the fairness, integrity, or

public perception of the trial.            See, e.g., United States v.

Takesian, 945 F.3d 553, 563 (1st Cir. 2019).             Because we see no

U.S.C. § 3592(c)(5) (providing for an aggravating factor where the
defendant "created a grave risk of death to 1 or more persons in
addition to the victim of the offense"). The legislative history
he quotes says that the "aggravating factors for which notice is
provided may include factors concerning the effect of the offense
on the victim and the victim's family" and that "[t]he effect on
the victim may include the suffering of the victim in the course
of the killing or during a period of time between the infliction
of injury and resulting death."     H.R. Doc. No. 102-58, at 166
(1991).
                                  - 117 -
error in any event, we need not resolve their dispute about the

standard of review.

            We can leave the resolution of the interpretive question

about the FDPA for another day, because (as the government notes)

even assuming without granting that Dzhokhar is correct here, the

surviving   spectators'   testimony   had     relevance   to   the   jury's

weighing of aggravating factors other than victim impact.56

            For organizational convenience, the survivors' testimony

Dzhokhar complains about can be grouped into these categories:

  1. "[R]eactions to facing death":         Jeffrey Bauman, for example,

     described making "peace" with death because he "had a great

     life."    Roseann Sdoia said she knew she "was bleeding out"

     but resolved to "stay calm and stay conscious" because if she

     panicked she "would die."    And Celeste Corcoran described how

     she at first "wanted to die" because she was in so much pain

     but realized she needed to "be there" for her family.

  2. "[U]ncertainty    about   what   had    happened   to   other   family

     members":    Eric Whalley, for instance, said he and his wife

     each thought the other had died.        And Stephen Woolfenden said

     he was "terrified" when first responders whisked his son away

     56 Dzhokhar accepts, as he must, that "surviving victims —
like any other witnesses — may testify at the penalty phase in
support of any properly alleged statutory or non-statutory
aggravating factor relating to the capital charges."
                                - 118 -
  because he "didn't know if [he] was ever going to see [him]

  again."

3. "[F]eelings of helplessness watching their injured child or

  partner suffer": Rebekah Gregory, for example, said she could

  hear   her   son   calling   "mommy"   after   the   blast   and   felt

  "helpless as a mother" because she could not go to him. Lying

  there on the pavement, she said a prayer, "God, if this is

  it, take me but let me know that Noah is okay."          And Jessica

  Kensky discussed her frustration at not being able to care

  for her husband (one of the bombs left his "foot and part of

  his leg . . . completely detached, hanging on kind of by a

  thin thread").

4. "[T]he   long-term   implications     of   becoming   an    amputee":

  Roseann Sdoia, for instance, said her amputation made it

  "extremely difficult" to learn to walk and run again, and to

  deal with the snow. Jessica Kensky said becoming a "bilateral

  amputee" was "terrifying."      She wanted to keep "some memory"

  of her legs, to "paint [her] toenails," and to "put [her]

  feet in the sand." And the pain from surgeries and treatments

  was "[a]bsolutely horrendous," putting her "in a very dark

  place" of "really not wanting to live" anymore.         And Adrianne

  Haslet-Davis said her husband could not attend the trial

  because he had checked himself into a mental-health facility.

                               - 119 -
              Given how low the relevance threshold is, we cannot say

that the judge slipped in finding this evidence at least minimally

relevant to an aggravating factor other than victim impact.

              The survivors' reactions to facing death (category 1)

helped show that Dzhokhar "knowingly created a grave risk of death

to 1 or more persons in addition to" the persons who died — a

statutory-aggravating factor.         See 18 U.S.C. § 3592(c)(5).        That

they felt they might die helps show they actually faced a grave

risk of death.      And their specific descriptions of what that felt

like   made    it   more   likely   that   the   jury   would   credit   their

statements about being at death's door. Plus their testimony could

help the jury in weighing the grave-risk-of-death factor as part

of its death-penalty decision.             See Sampson I, 486 F.3d at 44

(upholding admission of graphic evidence about a murder because it

"would help the jury to determine how much weight it should give"

the aggravating factors).           Above and beyond all that, their

testimony could help prove other aggravators — that Dzhokhar

substantially       planned   "an   act    of    terrorism,"    a   statutory-

aggravator, see 18 U.S.C. § 3592(c)(9); and that he "participated

in additional uncharged crimes of violence" like "assault with

intent to maim, mayhem[,] and attempted murder," a nonstatutory

aggravator.

                                    - 120 -
             The survivors' uncertainty regarding what happened to

their family members (category 2) was relevant to the grave-risk

of-death aggravator.      See id. § 3592(c)(5).         In most cases, family

members got separated because so many victims were on the verge of

dying that rescuers had to evacuate them as soon as possible.                  And

the multiple family separations highlighted how "grave" the "risk"

was.   The evidence was also relevant to the statutory terrorism

aggravator.    It is hard to think of anything more terrifying than

to   lose   track   of   one's   child    or   parent    in   a   life-or-death

situation.       The     evidence   was    additionally       relevant    to     a

nonstatutory aggravator — that he "targeted the Boston Marathon,"

an event "especially susceptible to the . . . effects of terrorism"

because of its "large crowds of men, women[,] and children."

             The survivors' feelings of helplessness as loved ones

suffered (category 3) was relevant for the same reasons.                   Their

inability to aid their family members after the bombings magnified

the terror that Dzhokhar sought to create.

             Finally, the testimony about the long-term implications

of becoming an amputee (category 4) helped establish the statutory

grave-risk-of-death aggravator.           The survivors' comments about

surgeries and suicidal thoughts showed that the risk of death

continued past the immediate aftermath of the bombings.                  And the

                                    - 121 -
long-term effects of their injuries were directly relevant to the

existence and weight of these factors.

            Enough said about the surviving victims' testimony.

                          Whole Foods Video

            We now take up Dzhokhar's challenge to the admission of

a video showing him buying milk at a Whole Foods soon after the

bombings.    What he essentially wants us to do is to remand for a

hearing on his claim that agents derived the video from involuntary

statements he made at the hospital after his arrest.     Each side

spends much energy debating two principal points.     The first is

whether Dzhokhar waived this claim — the government says he did

just that by not moving to suppress the video before trial; while

Dzhokhar says prosecutors made a pretrial promise not to use his

confession, which excuses any untimeliness in his raising the

claim.   The second is whether agents discovered the video through

an independent source untainted by any constitutional violations

— the government says a tip from Tamerlan's wife led agents to the

video; while Dzhokhar (noting the government identified her as the

tipster after he had filed his opening brief) says his involuntary

statements (not his sister-in-law's tip) steered the agents to the

video.   But because Dzhokhar is getting another penalty-phase

trial, the parties and the judge should address these matters —

e.g., was the source for the video genuinely independent of his

                               - 122 -
hospital confession, and if not, was the confession voluntary? —

if the government again opts to offer the video into evidence and

Dzhokhar objects.

                 An Expert's Testimony About ISIS
       and the Prosecution's Use of an Islamic Song and a
           Photo of Dzhokhar Raising His Middle Finger

          In the next section of his opening brief, Dzhokhar raises

three claims.   He first knocks the judge for wrongly admitting (in

the guilt phase) expert testimony on ISIS (the popular acronym for

the Islamic State of Iraq and Syria).        He then accuses the

prosecutor of committing misconduct by juxtaposing (in the guilt-

phase closing) a photo slideshow of the post-bombing carnage with

a recording of an Islamic song found on a computer in Tamerlan's

home that Dzhokhar used to surf the internet.       And he lastly

accuses another prosecutor of committing misconduct by displaying

(in the penalty-phase opening) posters of the four murder victims

beside a photo of him raising his middle finger at a cell-block

security camera.

                            Background

          Before trial, the defense had moved to exclude any expert

testimony "about terrorist leaders and attacks in which [Dzhokhar]

was not involved" unless the government could show that he knew of

the materials under discussion and "endorsed" or "absorbed" them.

The judge did not rule on the motion until just before the

                              - 123 -
prosecution called Dr. Matthew Levitt as an expert witness on

international terrorism during the guilt phase.             Recognizing that

Federal Rule of Evidence "403 is an important consideration," and

cautioning the government not to "step too far on this," the judge

denied the motion, saying that Levitt could "testify about the

history   of     recent    terrorist        activity,     particularly     the

encouragement of jihadi actions by particular prominent figures."

The government, for its part, promised to be "very sensitive" to

the defense's concerns.

             Levitt   talked   to   the    jury   about   the   "global   jihad

movement."     What drove this movement, he said, was not a formal

organizational structure but a decades-old "idea" that "there is

a need for a global effort on behalf of Muslims to unite as a

nation" and to "defend itself" through "acts of violence."                 The

movement's ideology, he added, permitted the killing of innocents

and focused its wrath on the United States.                 And, he further

explained, calling on followers to conduct independent terrorist

attacks "at home" had "become a major theme of radical propaganda."

             Levitt noted that this was true not only of "al-Qaeda"

but "now [also] the so-called Islamic state or ISIS."             The defense

objected to "bringing in" ISIS.           But the judge ruled the testimony

admissible "[a]s . . . general background."           Levitt then said that

"ISIS" — which both fought and cooperated with al-Qaeda — "is the

                                    - 124 -
latest   incarnation    of    this    global   jihad    movement."    And    he

explained that "ISIS, like al-Qaeda, has glossy magazines" and

"very impressive online radical and radicalization literature"

that tells supporters they "don't have to come" to a foreign

battlefield — "just do something back home."

           Later   in   his    testimony,      Levitt    described   how    the

conflict in the Russian republic of Chechnya had become a "rallying

cry" that jihadists used to "radicalize people."                He then said

that the "Syrian conflict" — which started "four years" before in

2011 — had also "become a rallying cry around the world."                   The

defense objected "to the whole discussion of Syria that goes beyond

the date of any of the events alleged in the indictment" — to which

the   judge   said,     "Overruled."      Levitt       then   explained    that

"[s]ticking even to the first two years of the Syrian conflict two

years ago," there were "different things that drew jihadis to this

conflict," including "jihadi ideology and want[ing] to go fight

with the next incarnation of al-Qaeda."

           We fast-forward to the prosecution's guilt-phase closing

arguments. There, the prosecutor argued that the Tsarnaev brothers

had been "radicalized to believe that jihad was the solution to

their problems."      He reviewed the evidence of Dzhokhar's radical

beliefs — which included Dzhokhar's boat manifesto, plus his

"library" of jihadist videos, writings, and "nasheeds" (Islamic

                                     - 125 -
chants) that Dzhokhar watched, read, and listened to on his

computer and other devices.       He noted that after the Tsarnaev

brothers carjacked Dun Meng, they "went back to Watertown" to get

"a CD containing those jihad nasheeds on it" for some "portable

inspiration" as they continued their escape.        He also noted that

Dzhokhar had created a twitter account with the display name

"Ghuraba" — an Islamic word that means "stranger."

           Later in his guilt-phase closing, the prosecutor said

that Dzhokhar had "murdered four people" and "wounded hundreds" to

"make a statement" and to "be a terrorist hero."           "This is how

[Dzhokhar] saw his crimes," the prosecutor stated while displaying

a PowerPoint presentation.     The presentation combined photos with

the audio of a nasheed.       Involving a singer chanting "Ghuraba"

repeatedly,   the   nasheed   played   over   a   slide   of   bombmaking

instructions (from Inspire, al-Qaeda's English-language magazine),

a photo of Dzhokhar seated in front of a black flag with Arabic

script, and three images of severely wounded victims in the

aftermath of the bombings.        The nasheed played for about 19

seconds.   After the chanting stopped, the prosecutor said that

"this is the cold reality of what his crimes left behind."           And

                                - 126 -
then he showed additional slides of the bombings' aftermath in

silence.

              Calling the prosecutor's playing "this haunting music

over    the   [photos]"    a   bid   to   "inflame    religious    or   ethnic

prejudice," the defense moved for a mistrial after the guilt-phase

summations and before the jury began deliberating (the defense did

not object during the closing, probably to not draw undue attention

to the presentation). The government responded that both the audio

file and the photos were in evidence and that the slideshow

provided      "perspective"    on    Dzhokhar's      "state   of   mind,   his

radicalization."     The judge denied the defense's motion, adopting

"the government's radicalization position."

              We now skip ahead to the prosecution's penalty-phase

opening statement.        There, the prosecutor displayed on easels 3-

foot by 4-foot photos of Lingzi Lu, Krystle Campbell, Sean Collier,

and Martin Richard.       A fifth easel in the middle had a black cloth

covering it.     Near the end of her statement, the prosecutor said:

       On July 10th, 2013, almost three months after Dzhokhar
       Tsarnaev had murdered Krystle Marie Campbell, Lingzi Lu,
       Martin Richard, and Officer Sean Collier, he was here in
       this courthouse. He knew the United States had charged
       him for his crimes. In the room that he was in, there
       was a video camera.     [He] was alone.    There was no
       brother with him. And once more, just as he had done
       with the boat [in Watertown], he had one more message to
       send.

                                     - 127 -
The prosecutor then pulled the black cloth off the middle easel,

revealing   a   3-foot    by   4-foot   photo   of   Dzhokhar   in   his   cell

thrusting his middle finger at a surveillance camera.            Concluding,

the prosecutor remarked:

     This is Dzhokhar Tsarnaev, unconcerned, unrepentant, and
     unchanged. Without remorse, he remains untouched by the
     grief and the loss that he caused.          And without
     assistance, he remains the unrepentant killer that he
     is. It is because of who [he] is that the United States
     will return and ask you to find that the just and
     appropriate sentence for [him] is death.

            After the opening statement, a lawyer for Dzhokhar noted

as a "point of record-keeping" that the prosecution had "displayed

the cell block photograph" during its opening.             Counsel claimed

"that the prejudicial" and "inflammatory" effect "of what we think

was an out of context and . . . quite distorted still [shot] from

the cell block was greatly enhanced . . . by its juxtaposition

between these very attractive and touching photographs of the

victims in life."    The judge did not comment on the issue.

                         Basic Appellate Arguments

            Dzhokhar calls Levitt's ISIS testimony both "irrelevant

and prejudicial," noting that the group (which he had no ties to)

"was well known for its barbarism at the time of his trial, but

unknown — indeed, hardly existent — at the time of his crimes."

He labels the prosecution's audiovisual presentation misconduct.

According to him, by "pairing religiously evocative images and

                                   - 128 -
gruesome photographs of the bombings, and overlaying both with an

Arabic chant," the prosecution "played to commonly held biases

against Muslims: that they are foreign, frightening, and violence-

prone."       And       he   alleges    an    instance      of   misconduct     in   the

prosecution's extracting the image of him "raising his middle

finger at a cellblock camera, juxtapos[ing] it with photographs of

the four decedents in the case, and then [telling] the jurors" —

"with no factual basis" — "that this obscene gesture was [his]

'message' to his victims."              All of which, his theory runs, shows

the jury voted for death under the influence of "[p]assion and

[p]rejudice."

              Taking the opposite view, the government argues that

Levitt's testimony was more pertinent than prejudicial, because

his comments helped the jurors see how the global jihad movement

inspires home-grown militants to commit "independent terrorist

attacks" — comments he delivered briefly and in an academic tone.

The   government        also    defends      the    propriety    of    the   PowerPoint

presentation, saying the playing of "a 19-second audio clip of a

nasheed   .    .    .    over   photos       of    [Dzhokhar]    and   the    bombing's

aftermath" were "tied specifically to the trial evidence regarding

[his] inspiration for the bombing."                   And the government sees no

prosecutorial       misconduct         regarding      the   middle-finger      poster,

because — contrary to the defense's representation — the prosecutor

                                         - 129 -
did not "say [Dzhokhar's] middle finger was a message 'to his

victims'" but instead only said that his "gesture was intended to

send the same 'message' that he had written in a boat before his

arrest, when he wrote that the bombings were a 'message' to the

United States Government."

                                 Analysis

             Taking first things first, we consider Levitt's guilt-

phase testimony.      Preserved relevance and prejudice claims, like

these   ones,    prompt   "abuse-of-discretion   review   —   a    famously-

deferential standard that requires a challenger to show that no

rational person could accept the judge's decision."               See United

States v. Rodríguez-Soler, 773 F.3d 289, 293 (1st Cir. 2014).            But

even deference has limits.      See United States v. Ayala-García, 574
F.3d 5, 18 (1st Cir. 2009).       And our deference reaches its limit

here.

           The relevance of Levitt's ISIS testimony is hard to see.

For example, we do not understand how the actions of a group that

did not meaningfully exist before Dzhokhar's crime could have made

any fact of consequence more likely (the government admits that

the threat posed by ISIS was generally "after the Boston Marathon

attacks").      See United States v. Kilmartin, 944 F.3d 315, 335 (1st

Cir. 2019) (emphasizing that "[e]vidence is relevant as long as it

has some tendency to make a fact of consequence more or less

                                 - 130 -
probable").      And calling the evidence "background," as the judge

did, does not move the needle.           Again, because ISIS barely existed

at the time of the bombings, Levitt's testimony could not have

provided      "background"   or    "stich[ed]      together   an   appropriate

context in which the jury could assess the evidence introduced

during the trial."      See United States v. McKeeve, 131 F.3d 1, 13

(1st   Cir.    1997).    And      by   falsely   linking   Dzhokhar    to   this

infamously brutal group, the unfair prejudicial effect of Levitt's

ISIS comments far outweighed any probative value that it had.

              But what saves the government is that this error is

harmless beyond a reasonable doubt.              See 18 U.S.C. § 3595(c)(2)

(explaining that a circuit court cannot reverse or vacate a federal

death sentence if the error is harmless beyond a reasonable doubt).

Running about two transcript pages, the contested testimony was

briefly given and tonally academic.              Plus an overwhelming amount

of other evidence showed that Dzhokhar drew inspiration from

radical Islamic propaganda, including from articles in a magazine

published by al-Qaeda (Inspire) and from lectures given by an Imam

connected to al-Qaeda.         So any suggestion during the guilt phase

that he got inspiration from another radical Islamic group (ISIS)

would not have affected the jury's sentencing verdict.                Moreover,

the jurors unanimously found the existence of several statutory

intent factors, statutory aggravating factors, and nonstatutory

                                       - 131 -
aggravating factors supported the death penalty.       And Dzhokhar

does not challenge the evidentiary support for any of them.     And

given the overwhelming force of these factors — driving home the

devastating effects of Dzhokhar's actions — we find beyond a

reasonable doubt that the jury would have imposed death even if

the judge had excluded the ISIS testimony.     See generally Jones,
527 U.S. at 404-05 (noting that a reviewing court doing a harmless-

error check of a death sentence can consider whether "the jury

would have reached the same conclusion" absent the error).

          Turning to the prosecutorial-misconduct claims, we note

that we review preserved claims de novo (that is, without giving

the district judge's decision any weight), and unpreserved claims

for plain error.   See, e.g., United States v. Sepúlveda-Hernández,

752 F.3d 22, 31 (1st Cir. 2014).        The parties dispute whether

Dzhokhar preserved all of his claims. But the dispute is academic,

because any error also fails on harmless-error review.

          When faced with a prosecutorial-misconduct allegation,

we first look to see if the prosecutors acted improperly.      See,

e.g., United States v. Veloz, 948 F.3d 418, 435 (1st Cir. 2020).

If they did, we then see if their misconduct "so poisoned the well

that the trial's outcome was likely affected," id. (quoting French,

904 F.3d at 124) — "weigh[ing] factors such as the severity of the

misconduct, the context in which it occurred, the presence or

                              - 132 -
absence     of       curative   instructions,   and      the    strength    of   the

evidence," United States v. Walker-Couvertier, 860 F.3d 1, 10 (1st

Cir. 2017).          Ultimately, reversal is justified "only where there

would     be     a    miscarriage   of   justice    or       where   the   evidence

preponderates heavily against the verdict."                     United States v.

Rodríguez-De Jesús, 202 F.3d 482, 486 (1st Cir. 2000) (quoting

United States v. Gonzalez-Gonzalez, 136 F.3d 6, 12 (1st Cir.

1998)).

               Both sides have strong arguments. As for the audiovisual

presentation, Dzhokhar correctly says that prosecutors offered no

proof that the nasheed used had any significance to him (let alone

that he ever played it or that it had any connection to the crimes

themselves), and they never played that nasheed during the trial.

And the government correctly notes that the presentation consisted

of photos and an accompanying audio file that the judge had

admitted into evidence.          Dzhokhar calls the presentation — scored

with    a      "foreign-sounding      soundtrack"        —     too   emotional    or

frightening, intended not to inform but "to stoke religious bias."

To this the government replies — with quotes from United States v.

Mehanna, 735 F.3d 32, 64 (1st Cir. 2013) (quotation marks omitted)

— that "terrorism-related evidence is often emotionally charged,"

even "alarming" and "blood curdling," yet "much of this emotional

overlay is directly related to the nature of the [terrorist]

                                      - 133 -
crimes." And, the government suggests, if that is true of Mehanna,

where the defendant committed no violent acts, it is all the more

reasonable to expect emotionally charged evidence and argument

here, where Dzhokhar partook in terrorist attacks that killed four

and grievously injured hundreds of others.

           Rather than resolving this close question, we assume

error — though the error did not irreversibly poison the well.       As

per usual, the judge told the jurors that counsel's arguments are

not evidence. And as required by the FDPA, see 18 U.S.C. § 3593(f),

the judge told them they could not consider Dzhokhar's religious

beliefs or national origin in deciding whether to recommend death.

Also as required by the FDPA, they specifically certified in the

penalty-verdict form that "consideration of the . . . religious

beliefs" or "national origin . . . of Dzhokhar . . . was not

involved in reaching" their decision.     Last but not least, in the

context of this case — with the overwhelming evidence of Dzhokhar's

devotion   to   radical   jihadist   ideology   and   with   his   guilt

unquestioned — the jury's penalty-phase verdict was not likely

affected by 19 seconds of music played weeks earlier during the

guilt phase.

           Sounding a familiar refrain, we note that each party

makes good points on the next issue too.    Dzhokhar insists that by

displaying the image of his middle-finger salute alongside photos

                               - 134 -
of those who had died, the prosecutor fueled the jurors' passions

by saying — without any factual support — that this was his

"message" to the murder victims.   The government insists that the

prosecutor never said that he was flipping off his victims —

rather, she said that what he did was meant to convey the same

"message" as his "boat" manifesto:   that a religious duty to wage

jihad against the United States justified his actions.    And the

government reminds us that courts do not lightly infer that a

prosecutor intends an "ambiguous remark" to carry its most harmful

meaning.   Not leaving that claim unanswered, Dzhokhar says that

given how the prosecutor displayed the photos, "[t]he inference

that these images were related to one another is not only the most

damaging meaning, but also the most obvious."

           Yet even if the government is wrong and Dzhokhar is

right, he cannot win.      The evidence overwhelmingly showed his

disdain for his victims.    Far from simply gesturing at them, he

set off a bomb designed to kill them by sending pieces of metal

tearing through their bodies.      And after doing this, he later

tweeted that he was "a stress free kind of guy."   So even if the

jurors understood the prosecutor as saying that Dzhokhar directed

his middle-finger salute at his victims, the prejudice from that

inference would pale when compared with evidence of his violently

and intentionally killing them — without showing any remorse.

                              - 135 -
          Even   though   the    government    won     the   prosecutorial-

misconduct   challenges   on     harmless     error,    we   suggest   that

prosecutors not to repeat these tactics on remand.           And by tactics

we mean the prosecution's (a) showing the jury a photo slideshow

of the post-bombing carnage scored with a nasheed that had zero

connection to the crime itself; and (b) displaying a poster-sized

photo of Dzhokhar sticking out his middle finger placed between

the same-sized photos of the decedents, thereby implying his

gesture constituted his "message" to the victims — even though no

evidence showed he in fact directed his gesture toward the victims.

                 Penalty-Phase Jury Instructions
        About Weighing Aggravating and Mitigating Factors

          We turn our attention to Dzhokhar's suggestion that the

judge stumbled by not telling the jurors that to recommend death

they had to find beyond a reasonable doubt that the aggravating

factors outweighed any mitigating ones.

                                Background

          To place the matter into proper perspective (and to save

the reader from having to flip back to a footnote many pages ago),

we highlight certain aspects of how capital sentencing works.          For

a defendant to get a death sentence under the FDPA, the jurors

must make several penalty-phase determinations — including:            they

must find unanimously and beyond a reasonable doubt that he acted

with the statutorily required intent, see 18 U.S.C. § 3591(a)(2);
                                 - 136 -
they must find unanimously and beyond a reasonable doubt that at

least one statutory aggravator is present, see id. § 3593(e)(2);

see also id. § 3592(c); and they must find unanimously that the

aggravators (statutory and nonstatutory) sufficiently outweigh any

mitigators, see id. § 3593(e).

             Before   the    penalty-phase    deliberations      started,      the

defense asked the judge to tell the jurors that they could only

call for Dzhokhar's death if they found the aggravators outweighed

any mitigators "beyond a reasonable doubt."             Without hearing any

argument, the judge said that "Circuit law" precluded him from

giving an instruction like that.            The judge probably had in mind

Sampson I — a case holding that because "the requisite weighing

constitutes a process, not a fact to be found," a jury need not

make the weighing determination beyond a reasonable doubt.                  See
486 F.3d at 32.

                        Basic Appellate Arguments

             The Supreme Court tells us "that only a jury, and not a

judge, may find [beyond a reasonable doubt] facts that increase a

maximum penalty, except for the simple fact of a prior conviction."

See Mathis v. United States, 136 S. Ct. 2243, 2252 (2016) (citing

Apprendi v. New Jersey, 530 U.S. 466, 490 (2000)).               Dzhokhar says

that   the   weighing       determination    is   a   "fact[]"    that   ups    a

defendant's "maximum possible punishment from life to death."                  So

                                    - 137 -
he argues that the judge erred by not telling the jurors that they

had to find the aggravators outweighed the mitigators under the

reasonable-doubt standard.           He admits that Sampson I forecloses

his claim.       But he thinks that the Supreme Court "abrogated"

Sampson I in Hurst v. Florida, 136 S. Ct. 616 (2016).

              The government disagrees.          Sampson I, the government

says, is still good law because nothing in Hurst weakens Sampson

I's holding that the "outweighs" decision — coming into play only

after   the    jurors   find   the    defendant    death-eligible   beyond   a

reasonable doubt — is not a fact determination, but a moral one

about what is just.

                                     Analysis

              Dzhokhar's claim rises or falls on the notion that Hurst

requires that jurors make the weighing determination beyond a

reasonable doubt.       Using our independent (or de novo) judgment,

see Sampson I, 486 F.3d at 29, we think his argument must fall.

              Hurst invalidated Florida's capital-sentencing scheme.

See 136 S. Ct. at 619-20. Under that scheme, "the maximum sentence

a capital felon" could get based on "the [jury] conviction alone

[was] life imprisonment." Id. at 620.      He could get a death

sentence only if the judge later determined that (1) "sufficient

aggravating      circumstances       exist"     and   that   (2) "there   are

insufficient mitigating circumstances to outweigh the aggravating

                                     - 138 -
circumstances." Id. at 620, 622 (quotation marks omitted).   Hurst

said that determination (1) — that sufficient aggravators exist —

violated the defendant's constitutional right to a jury trial,

because it "impermissibly allowed 'a sentencing judge to find an

aggravating circumstance, independent of a jury's factfinding,

that is necessary for imposition of the death penalty.'" McKinney,
140 S. Ct. at 707 (quoting Hurst, 136 S. Ct. at 624).                But

importantly here, Hurst made no holding regarding determination

(2) — that the mitigators do not outweigh the aggravators.           See
136 S. Ct. at 624 (summarizing the case as holding that Florida's

sentencing procedure, "which required the judge alone to find the

existence    of   an   aggravating    circumstance,   is   .     .     .

unconstitutional" (emphasis added)).

            About a week after Hurst came out, the Supreme Court

issued Kansas v. Carr.    Carr held that the Constitution does not

"require[] capital-sentencing courts . . . to affirmatively inform

the jury that mitigating circumstances need not be proven beyond

a reasonable doubt."     See 136 S. Ct. 633, 642 (2016) (quotation

marks omitted).   In doing so, Carr

     doubt[ed] whether it is even possible to apply a standard
     of proof to the mitigating-factor determination . . . .
     Whether mitigation exists . . . is largely a judgment
     call (or perhaps a value call); what one juror might
     consider mitigating another might not.

                               - 139 -
Id.    And then Carr emphasized the discretionary nature of the

weighing process, saying

      the ultimate question whether mitigating circumstances
      outweigh aggravating circumstances is mostly a question
      of mercy — the quality of which, as we know, is not
      strained. It would mean nothing, we think, to tell the
      jury that the defendants must deserve mercy beyond a
      reasonable doubt; or must more-likely-than-not deserve
      it.
Id. (emphasis added).57

           Carr causes problems for Dzhokhar in two ways.        One, if

the Supreme Court in Hurst intended to impose the reasonable-doubt

standard on the weighing process — as Dzhokhar argues — the Court

in Carr would not have said days later that telling the jury to

use that standard "would mean nothing."        And two, Carr's "mercy"

talk supports Sampson I's statement that "[t]he outcome of the

weighing process is not an objective truth that is susceptible to

(further) proof by either party."      See 486 F.3d at 32.

           Now   consider   McKinney   v.   Arizona,   a   Supreme   Court

opinion from this year.     McKinney held that while cases like Hurst

require a jury to "find the aggravating circumstance that makes

      57Dzhokhar calls this passage "dicta" that we can disregard.
But Supreme Court dicta are different from other judicial dicta,
because "we 'are bound by the Supreme Court's considered dicta
almost as firmly as by the Court's outright holdings.'"        See
LaPierre v. City of Lawrence, 819 F.3d 558, 563-64 (1st Cir. 2016)
(quoting Cuevas v. United States, 778 F.3d 267, 272-73 (1st Cir.
2015)).
                                - 140 -
the defendant death eligible," they "did not require jury weighing

of aggravating and mitigating circumstances."          See 140 S. Ct. at

707-08 (holding that an appellate court can reweigh aggravators

and   mitigators   if   the   judge   failed   to   properly   consider   a

mitigator).   So McKinney helps sink Dzhokhar's claim that Hurst

requires the jury to make the weighing determination beyond a

reasonable doubt — a view we hold because McKinney makes crystal

clear Hurst addressed only the finding of aggravating facts and

had nothing to do with the weighing process.

           The bottom line of this discussion is that our Sampson

I opinion — holding that the reasonable-doubt standard does not

apply to the weighing process — remains good law.58

                   Penalty-Phase Jury Instructions
                         About Jury Deadlock

           Dzhokhar makes a second claim of instructional error:

that the judge botched the proceedings by not telling the jurors

that failure to reach a unanimous recommendation on the death

      58Dzhokhar takes another dig at Sampson I, arguing that
Sampson I "failed to take account of" United States v. Gaudin, 515
U.S. 506 (1995). Gaudin held that a jury must decide whether a
criminal defendant "is guilty of every element of the crime with
which he is charged, beyond a reasonable doubt." Id. at 510. And
Gaudin further held that materiality, as an element of a false-
statement crime under 18 U.S.C. § 1001, is a mixed question of law
and fact for the jury to resolve. Id. at 511-12, 522. But nowhere
did Gaudin suggest that the weighing determination is an element
or fact that a jury must find applying a reasonable-doubt standard.
So Gaudin does not help Dzhokhar.
                                 - 141 -
penalty would result in his imposing a life sentence without the

possibility of release.

                                  Background

             As a matter of helpful repetition, we emphasize again

that jurors in a federal capital case cannot recommend that a

defendant die unless (as relevant here) they unanimously find

beyond   a   reasonable   doubt    a   requisite   intent   factor   and   an

aggravating circumstance, and then unanimously find that all the

aggravators outweigh any mitigators to justify his getting death.

See Jones, 527 U.S. at 376-77 (reviewing the FDPA).            And if they

cannot make a unanimous recommendation, the judge steps in and can

impose either a life sentence without release or any lesser

sentence allowed by law.      See id. at 380-81.       The parties concur

that jury deadlock on any of these prerequisites here would have

resulted in a sentence of life without release.

             With this understanding in place, we return to the

particulars of Dzhokhar's case — right before the penalty-phase

deliberations.     The defense asked the judge to tell the jurors

that he would impose a sentence of life without release if, after

weighing the aggravating and mitigating circumstances, they could

not unanimously agree on a sentencing recommendation. The proposed

instruction read:

     If the jury is unable to reach a unanimous decision in
     favor of either a death sentence or of a life sentence,
                                   - 142 -
      I will impose a sentence of life imprisonment without
      possibility of release upon the defendant. That will
      conclude the case. At this sentencing stage of the case,
      the inability of the jury to agree on the sentence to be
      imposed does not require that any part of the case be
      retried. It also does not affect the guilty verdicts
      that you have previously rendered.

           The defense conceded that the Supreme Court's Jones

decision "authorize[d] district courts" to refuse to give such an

instruction.      See 527 U.S. at 381 (holding that judges are not

required to instruct sentencing juries on the consequences of a

deadlock in the weighing process).          But the defense claimed that

without it, the jury might "wrongly assume that a failure to agree

on sentence would require the case to be retried before a new

jury."    And   this   mistaken   belief,     the   defense   added,   would

"coerc[e]" some jurors into accepting a death verdict to avoid

having to "put the victims and the survivors and the entire

community through this entire case again."

           The judge rejected the defense's request, saying that

the   suggested     instruction   could     "undercut[]"      the   "process

anticipated by" the FDPA by essentially empowering "one juror" to

"simply decid[e] that the decision was his or hers" without

sufficiently engaging in the deliberative process.            But the judge

explained that he would address the defense's coercion concerns by

giving "a very strong instruction" that "each individual juror is

                                  - 143 -
to give his or her own [verdict] and not agree just to agree with

others."

             After    the       parties   presented     their       penalty-phase

evidence, the judge told the jurors that they had to decide —

unanimously and beyond a reasonable doubt — whether the government

established the existence of one of the "gateway" mental-intent

factors (which we will later discuss) and one of the statutory

aggravating factors.          The judge noted that if they could not so

agree, he then would sentence Dzhokhar to life imprisonment without

release.     But the judge said that if they could so agree, they

then   had   to    consider     whether   the    aggravators    outweighed   any

mitigators to justify a death sentence. And if, after the weighing

process, they unanimously found that death or life without release

was the proper sentence, the judge stated that they should mark

the corresponding part of the verdict form.

             The judge did not instruct the jurors about what would

happen if they deadlocked in making a sentencing recommendation.

But he did tell them that "[b]efore you reach any conclusion based

on a lack of unanimity on any count, you should continue your

discussions       until   you    are   fully     satisfied   that    no   further

discussion will lead to a unanimous decision."               And he emphasized

that "[a]ny one of you is free to decide that a death sentence

should not be imposed," that "[e]ach juror must individually

                                       - 144 -
decide" whether to recommend death, and that "no juror is ever

required to impose a sentence of death."

             The defense later objected to the judge's "refusal" to

instruct the jurors about what would occur if they deadlocked on

the penalty recommendation.

                       Basic Appellate Arguments

             Dzhokhar criticizes the judge for not telling the jurors

that if they could not unanimously agree on whether to recommend

death, then he (Dzhokhar) would automatically get life without

release.     He thinks this because to him the jurors likely drew a

"negative inference" from the instructions at earlier stages —

i.e., that because the judge said that deadlock at the intent and

aggravator stages would result in an automatic life sentence

without release, his not saying anything about deadlock at the

weighing stage would cause them to infer that the "failure to reach

unanimity" there "would yield a result other than a mandatory life

sentence."      And,   still   repeating    arguments   made   below,     this

"omission[]"     (to   quote   again   from   his   brief)     "created     an

intolerable risk of coercing holdout jurors for life to acquiesce

in a death verdict in order to spare the victims' families, the

                                  - 145 -
survivors, and the Boston community the significant financial and

emotional strain" of a second penalty-phase "trial."

          The government takes a diametrically opposed position.

It says that the judge's decision not to instruct about the effect

of a deadlock on the sentence decision squares with the Supreme

Court's Jones opinion. It also says that Dzhokhar's argument about

the jurors drawing a negative inference "is speculative at best"

and so cannot undermine the judge's ruling.

                               Analysis

          The   parties   disagree   about   what   standard   of   review

applies to this claim.    We review anew (de novo, as the cases say)

preserved claims that the jury instructions mislead the jurors,

"taking into account the charge as a whole and the body of evidence

presented at trial." Sampson I, 486 F.3d at 29. Dzhokhar believes

he said enough below to preserve his arguments.          The government

believes differently. But we assume without deciding that Dzhokhar

is correct because he loses here under either standard.

          Jones lights the path to decision.        Construing § 3594 of

the FDPA, Jones held that if the jury fails to reach a unanimous

verdict on punishment for a capital crime, the judge must enter a

sentence other than death — so there is no mistrial or second

                               - 146 -
penalty-phase proceeding.59      See 527 U.S. at 380-81.          Jones also

held that a judge need not tell the jurors about the consequences

of deadlock at that stage.        See 527 U.S. at 381, 384.         "[I]n a

capital sentencing proceeding," Jones explained, "the Government

has 'a strong interest in having the jury express the conscience

of the community on the ultimate question of life or death.'" Id.

at 382 (quoting Lowenfield v. Phelps, 484 U.S. 231, 238 (1988)).

And telling the jurors about the consequences of nonunanimity,

Jones said, could undermine those vital interests because it might

amount    to   "an   open   invitation    for   the   jury   to   avoid   its

responsibility and to disagree." Id. at 383-84 (quoting Justus v.

Virginia, 266 S.E.2d 87, 92 (Va. 1980)).         Jones also stressed that

if a defendant thinks the judge's charge "caused jury confusion,"

he must show "a reasonable likelihood that the jury has applied

     59   Section 3594 says:
     Upon a recommendation under section 3593(e) that the
     defendant should be sentenced to death or life
     imprisonment without possibility of release, the court
     shall sentence the defendant accordingly.     Otherwise,
     the court shall impose any lesser sentence that is
     authorized by law. Notwithstanding any other law, if
     the maximum term of imprisonment for the offense is life
     imprisonment, the court may impose a sentence of life
     imprisonment without possibility of release.
18 U.S.C. § 3594.
                                  - 147 -
the challenged instruction[s]" in a legally flawed way. Id. at

390 (quoting Estelle v. McGuire, 502 U.S. 62, 72 (1991)).

          Dzhokhar has not shown a reasonable likelihood that the

jury applied the instructions incorrectly.          Our reasons for so

concluding are threefold.

          In the first place, the judge's instructions that he

would sentence Dzhokhar to life without release if the jury

deadlocked at the intent-and-aggravator-factor stages passed legal

muster.   See Jones, 527 U.S. at 380-81.      So too did the judge's

decision not to instruct on the effect of their deadlocking on the

sentence decision.   See id. at 381-84.    Devastating to his claim,

Dzhokhar cites no precedent holding that if the judge instructs on

the effect of an impasse at one stage, he must also do so at every

other stage.

          In   the   second   place,   Dzhokhar's   negative-inference

theory — the omission of a consequences-of-deadlock instruction at

the weighing stage signaled to the jury that a deadlock there would

lead to a mistrial and a new penalty phase — rests on nothing but

speculation.   See Carr, 136 S. Ct. at 643 (stressing that "[a]

meager 'possibility' of confusion is not enough" (quoting Boyde v.

California, 494 U.S. 370, 380 (1990))).     We doubt that the jurors

recognized the inconsistency that his lawyers see, particularly

since "[j]urors do not sit in solitary isolation booths parsing

                                - 148 -
instructions for subtle shades of meaning in the same way that

lawyers might."     See Brown v. Payton, 544 U.S. 133, 143 (2005)

(quoting Boyde, 494 U.S. at 380-81).             But even indulging his

speculative inference drawing, we think that the jurors were at

least as likely to conclude that the effect of a deadlock at the

weighing stage would be the same as at the earlier stage — i.e.,

that the judge would hand down a sentence of life without release.

And even assuming the jurors wanted to avoid a new penalty phase,

we believe the instructions could just as easily have caused them

to compromise by choosing to recommend life without release.

Anyhow, their verdict shows they did not feel compelled to return

a death verdict, given how they recommended life on 11 of the 17

death-eligible counts.

             Also hurting Dzhokhar is that Jones rejected a similar

negative-inference claim.      The Jones defendant claimed that an

alleged ambiguity in the instructions might have caused the jury

to think that if it failed to reach unanimity on the sentencing

issue, the judge might give him a term less severe than life

without release. 572 U.S. at 387.          But Jones rebuffed this

negative-implication argument, holding that the defendant had

"parse[d]"    the   instructions    "too     finely"   and   that   —   after

considering the instructions as a whole — the inferences he relied

                                   - 149 -
on did not "create a reasonable likelihood" of confusion over the

deadlock's effect. Id. at 391-92.

           In   the   third    place    and     finally,   Dzhokhar   cites   no

authority holding that an instruction that is constitutionally

permissible can become unconstitutionally coercive by ambiguous

negative   inferences       drawn   from   other   instructions.      That    is

probably because the caselaw is against him. For Jones holds "that

instructions that might be ambiguous in the abstract can be cured

when read in conjunction with other instructions." Id. at 391.

And reviewing the instructions holistically — instructions that

stressed that "[a]ny [juror] is free to decide that a death

sentence   should     not    be     imposed,"    that   "[e]ach    juror   must

individually decide" whether to recommend death, and that "no juror

is ever required to impose a sentence of death" (which we presume

they obeyed, see Marsh, 481 U.S. at 206) — we see no basis for

Dzhokhar's conjecture that any juror was coerced into voting for

a death sentence to avoid causing a mistrial.

                         Ex-Parte Communications

           Up for review here is Dzhokhar's claim that a "secret

channel of communication" existed between prosecutors and the

                                     - 150 -
judge — "repeated private access" that violated his constitutional

rights to due process and effective assistance of counsel.

                              Background

           During Dzhokhar's prosecution, the government filed a

number of documents ex parte.    And the judge held a number of ex-

parte conferences with the government.     All of this resulted in 26

ex-parte docket entries, involving 4 court orders, 16 government

motions or notices, and 6 ex-parte conferences.

           As Dzhokhar's appeal moved along, the government (with

the judge's approval) voluntarily disclosed 13 of the ex-parte

filings to the defense. After some motion practice, the government

disclosed a lightly-redacted transcript of an ex-parte conference

on the Waltham evidence.   So 12 ex-parte items remain undisclosed.

                     Basic Appellate Arguments

           The nub of Dzhokhar's argument is that the judge's "back-

channel talks" with the government robbed him of his "Fifth

Amendment right to due process and his Sixth Amendment right to

the assistance of counsel."    Quoting a decision from us, he points

out that

     not only is it a gross breach of the appearance of
     justice when the defendant's principal adversary is
     given private access to the ear of the court, it is a
     dangerous procedure [because it invites the question
     whether] "[t]he firmness of the court's belief [in the
     prosecutor's position] may well have been due not only
     to the fact that the prosecutor got in his pitch first,

                                - 151 -
       but, even more insidiously, to the very relationship
       . . . that permitted such [ex parte] disclosures."

See Haller v. Robbins, 409 F.2d 857, 859-60 (1st Cir. 1969).            And

he notes that the constitutional right to counsel applies to all

critical stages of the prosecution.            See Lafler v. Cooper, 566
U.S. 156,    165   (2012)   (underscoring   that   this   "constitutional

guarantee applies to pretrial critical stages that are part of the

whole course of a criminal proceeding, a proceeding in which

defendants cannot be presumed to make critical decisions without

counsel's advice").

               Seeing no violations, the government insists that the

in-camera procedures helped the judge "to independently assess

whether the materials were discoverable" — and because they "were

not" discoverable, Dzhokhar had "no right to obtain them."                As

support, the government stresses that a judge's ex-parte, in-

camera review of documents may be authorized under the Classified

Information Procedures Act and Criminal Rule 16(d)(1).            See United

States v. Pringle, 751 F.2d 419, 426-28 (1st Cir. 1984).60               And

        "[E]nacted to limit the practice of criminal defendants
       60

threatening to disclose classified information . . . to force the
government to dismiss the charges," the Classified Information
Procedures Act (among other things) lists a series of rules for
preserving confidentiality of classified information and for
allowing discrete use of such information. See Dhiab v. Trump,
852 F.3d 1087, 1092 n.9 (D.C. Cir. 2017).        That Act defines
"[c]lassified information," in relevant part, as "any information
or material that has been determined by the United States
Government pursuant to an Executive order, statute, or regulation,
                              - 152 -
quoting     one   of   our   cases,    the   government   adds   that   the

"requirements of confidentiality [can] outweigh the interest in

adversarial litigation and permit a court to rule on an issue in

camera and without the participation of an interested party."           See

United States v. Innamorati, 996 F.2d 456, 487 (1st Cir. 1993).

                                 Analysis

            The interests on each side of this controversy are

profound.      And both parties have points in their favor.             But

reviewing Dzhokhar's legal challenge de novo, see United States v.

Lustyik, 833 F.3d 1263, 1267 (10th Cir. 2016) — i.e., without

giving the judge's take any special weight — we side with the

government.

            A criminal defendant's right to an adversary proceeding

is central to our system of justice.          See, e.g., Innamorati, 996
F.2d at 487.      That right includes the right to have counsel at all

critical stages of the criminal process.        See, e.g., United States

v. Cronic, 466 U.S. 648, 654, 659 (1984).           But the law permits

some exceptions to this norm.         See, e.g., Innamorati, 996 F.2d at

487.   In exceedingly "rare situations" a judge may act in camera

to require protection against unauthorized disclosure for reasons
of national security." 18 U.S.C. app. 3 § 1(a). And Criminal
Rule 16(d)(1) provides that "[t]he court may permit a party to
show good cause [for an order restricting discovery] by a written
statement that the court will inspect ex parte."
                                  - 153 -
and with the benefit of only the prosecution's views, like when

there is a need to stop disclosure of sensitive information — for

example    (and   without   limitation),   material   that   could   damage

national security, see id., compromise an in-progress criminal

inquiry, see Puerto Rico, 490 F.3d at 64, or fall outside the rule

of Brady v. Maryland, see United States v. Claudio, 44 F.3d 10, 14

(1st Cir. 1995).61    And because the point is so powerful and cannot

be made enough, we repeat what we said in Innamorati:

     Outside of emergencies, . . . the ex parte submission of
     information from a party to the court and the court's
     ruling on that information without notice to or
     participation of the opposing party is fundamentally at
     odds with our traditions of jurisprudence . . . and can
     be   justified   only   in    the   most   extraordinary
     circumstances.
996 F.2d at 487.

            The "burden of justification" here is on the government.

See Claudio, 44 F.3d at 14.      And it is a burden the government has

carried.

            The government notes that aside from a few documents on

a restitution issue (which the judge never ruled on), all of the

remaining ex-parte items involve "either classified or otherwise

sensitive material" that prosecutors gave the judge for an in-

     61Generally speaking (and as noted earlier), Brady requires
the prosecution to give the accused information that is both
favorable and material to guilt or punishment. See 373 U.S. at
87.
                                 - 154 -
camera review to see if "the material should be protected from

disclosure or should instead be produced to the defense."62            Asking

us to take his side, Dzhokhar zeroes in on an ex-parte proceeding

held after the defense filed a motion challenging the prosecution's

proposed trial exhibits. With the benefit of only the government's

presentation, the judge there offered some suggestions about how

the evidence could best be shown at trial.         But neither he nor the

government touched on Dzhokhar's objections.         We do not understand

why the judge had to consider this presentation issue on an ex-

parte     basis.     But   given   the   "unimportance   of   the   material"

discussed at this brief hearing, any error "inflicted no prejudice"

on Dzhokhar.       See Innamorati, 996 F.2d at 488.

             As for the other ex-parte communications, we think that

the necessity to keep sensitive information from the defense

sufficiently justified the procedures employed in this case.              And

not for nothing, but these ex-parte measures actually helped

protect Dzhokhar's due-process rights, for they allowed the judge

to review and rule on the materials' discoverability — rather than

leaving the decision in the hands of prosecutors.             See generally

Pennsylvania v. Ritchie, 480 U.S. 39, 59 (1987) (explaining that

     62 The government has given Dzhokhar's appellate counsel and
us a document (filed under seal) describing the ex-parte materials
and explaining why the defense should not get them.
                                    - 155 -
"[i]n the typical case where a defendant makes only a general

request for exculpatory material under Brady . . ., it is the

[government] that decides which information must be disclosed").

On this point Innamorati put it best:          "[T]he interests of justice

are better served by encouraging the government to let the district

court resolve" concerns about sensitive information "in close

cases"; and a "[d]efendant[] in general would not gain from a

regime that encouraged the government to decide the matter itself."

See 996 F.2d at 488.     See also generally Ritchie, 480 U.S. at 59-

60 (finding the defendant's interest in discovering exculpatory

information adequately protected by trial court's in-camera review

of sensitive materials).

            Dzhokhar does not gain any more traction by turning to

the judge's ex-parte, in-camera handling of the Todashev material

— proceedings prompted by the government's pressing the qualified

law enforcement investigatory privilege.          True, we today hold that

the judge erred by denying the defense access to these items.           But

the   potentially    sensitive   nature   of    the   information   involved

justified   the     judge's   "initial"   ex-parte     examination.      See

Innamorati, 996 F.2d at 488.      Which is why we applaud rather than

criticize the judge's use of established protocols for assessing

the merits of this privilege claim.

                                  - 156 -
             Not only does Dzhokhar's due-process argument collapse

— his right-to-counsel argument does too.

             Citing Cronic, Dzhokhar insists that "[t]he ex parte

communications concerning contested discovery" violated his right

to counsel at a "critical stage" of his prosecution.           Cronic held

that if a defendant was completely denied the right to counsel for

a "critical stage" of the trial, we irrebuttably presume that it

was harmful (we do not ask whether the error was harmless).              See
466 U.S. at 659 & n.25; see also Bell v. Cone, 535 U.S. 685, 695-

96   (2002).     But   Dzhokhar    never   explains   how   these   ex-parte

proceedings qualified as critical stages.        Then there is the just-

discussed caselaw saying that ex-parte review is appropriate in

those "rare" instances where the need to keep sensitive information

from   the     opposing    party     "outweigh[s]     the    interest"   in

inquisitorial proceedings.        See Innamorati, 966 F.2d at 487.       See

also generally Ritchie, 480 U.S. at 60 (recognizing that ex-parte

proceedings "den[y]" the defendant "the benefits of an 'advocate's

eye,'" but finding no constitutional problem there because the

trial judge was "obligated to release information material to the

fairness of the trial").          And that takes care of his right-to-

counsel theory.

             We end here with a caveat.      This is a jury trial, not a

bench trial where the judge decides the facts.          And our reasoning

                                   - 157 -
does    not    necessarily   apply   to   the   latter   without   further

consideration.

                     Fair-Cross-Section Requirement

              Dzhokhar contends that an underrepresentation of African

Americans in the grand and petit jury wheels violated his right to

an impartial jury selected from a fair cross-section of the

community.63     He calls the statistical methodology that our circuit

uses to determine underrepresentation — the absolute-disparity

method — "legally and statistically unsound."64          Conceding that we

as a three-judge panel are stuck with this circuit's approach, he

says that he raises the issue simply to preserve it for possible

"en banc or Supreme Court review."         So "[f]or present purposes,"

he adds, "nothing else need be said" — a point with which we agree.

        A jury wheel is "[a] physical device or electronic system
       63

used for storing and randomly selecting names of potential jurors."
See Jury Wheel, Black's Law Dictionary (11th ed. 2019). A grand
jury decides whether to indict a suspect. See Grand Jury, Black's
Law Dictionary (11th ed. 2019). And a petit jury decides whether
to convict the indictee.     See Jury:    Petit Jury, Black's Law
Dictionary (11th ed. 2019).
        The absolute-disparity method "measures the difference
       64

between the percentage of members of the distinctive group in the
relevant population and the percentage of group members on the
jury wheel." United States v. Royal, 174 F.3d 1, 6-7 (1st Cir.
1999) (discussing United States v. Hafen, 726 F.2d 21, 23 (1st
Cir. 1984)).

               Death Penalty for Offenders Under Age 21

             That takes us to Dzhokhar's constitutional claim that as

a person accused of having committed death-eligible crimes when he

was under 21 (he was 19 at the time of the bombings), he is

"categorically exempt from the death penalty."

             Citing Roper v. Simmons, 543 U.S. 551 (2005), Dzhokhar

concedes — as he must — that the Supreme Court has "dr[awn] a

bright line" for death eligibility "at age 18."                 He just thinks

that the factors Roper considered relevant in granting death-

penalty immunity to persons under 18 — that they lack the maturity

we attribute to adults; that they are more vulnerable to peer

pressure than are adults; and that their personality traits are

less fixed, suggesting a higher likelihood of rehabilitation of

juveniles than of adults, see id. at 569-79 — apply equally to

persons under 21.        Looking for support, he argues that "scientific

research"     since     Roper   "has    explained    the     effects    of    brain

maturation, or the lack thereof, on the behavioral and decision-

making abilities of late adolescents in their late teens and early

twenties."        He   also   says   that   there   is   a   "growing   national

consensus against the death penalty" for offenders between 18 and

20.         See        Am.    Bar    Ass'n,      Resolution      111         (2018),

https://www.americanbar.org/content/dam/aba/images/abanews/mym20

18res/111.pdf.

                                       - 159 -
            Unimpressed,        the       government     writes      that     Dzhokhar

discusses       no    research      about       "brain    maturation         that   is

substantially different from the research available" at the time

Roper came down.          Citing one of his sources, the government also

writes that "not a single state with an active death penalty

scheme" bans the execution of 18-to-20-year-olds.                       And if the

United States made that group death-penalty immune, the government

adds, quoting another of his sources, it "would be taking an

unusual legal stance with respect to prevailing international

norms."

            Because Dzhokhar did not raise this issue below, we

review    for    plain     error      —    reversing     only   if    (among    other

requirements)        he   can    show      an   "indisputable"       error,    "given

controlling precedent."            See United States v. Correa-Osorio, 784
F.3d 11, 22 (1st Cir. 2015).                This he cannot do, however, given

Roper's square holding that 18 is "the age at which the line for

death eligibility ought to rest."               See 543 U.S. at 574.        The change

he proposes is certainly worthy of careful consideration.                           As

members of what the Constitution calls an "inferior" court, see

U.S. Const. art. III, § 1, we simply note that whether a change

should occur is for the Supreme Court to say — not us, see Morey

v. United States, 903 F.2d 880, 883 (1st Cir. 1990).

                                          - 160 -
                            Crime of Violence

            We end with Dzhokhar's challenge to five convictions for

using a firearm during a "crime of violence."

                                 Background

            The jury convicted Dzhokhar of (among other crimes)

multiple violations of 18 U.S.C. § 924(c).          As relevant here, that

section    has   two   prongs:    the   "use   or   carry"   prong    and   the

"possession" prong.      The first punishes anyone who "during and in

relation to any crime of violence . . . uses or carries a firearm."
Id. § 924(c)(1)(A) (emphasis added).           The second punishes anyone

who "in furtherance of any such crime[] possesses a firearm." Id.

(emphasis added).65       The statute carries hefty minimum prison

terms, especially for recidivists (and these sentences are over

and above the ones they get for the underlying crime).                See id.

§ 924(c)(1)(A)-(C).        Another   provision      increases   the   maximum

penalty to death if the defendant, "in the course of a violation

of subsection (c)," kills "a person through the use of a firearm"

and the killing is a murder as defined in the federal murder

statute.    See id. § 924(j)(1).

     65 Critically for present purposes, "firearm" includes
"destructive device[s]" such as bombs. See 18 U.S.C. § 921(a)(3)-
(4).
                                  - 161 -
            Section 924(c) defines "crime of violence" (a phrase we

italicized above) as "an offense that is a felony" and

      (A) has as an element the use, attempted use, or
      threatened use of physical force against the person or
      property of another, or

      (B) that by its nature, involves a substantial risk that
      physical force against the person or property of another
      may be used in the course of committing the offense.
Id. § 924(c)(3). Courts commonly call subsection (A) the "elements

clause" (sometimes also referred to as the "force clause") and

subsection (B) the "residual clause."          See, e.g., United States v.

Davis, 139 S. Ct. 2319, 2324 (2019).

            Two methods exist for deciding if a prior crime is a

crime of violence:      the "categorical approach" and the "modified

categorical approach."         See, e.g., United States v. Taylor, 848
F.3d 476, 491-92 (1st Cir. 2017).

            If   the   prior     crime    involved   a   violation    of    an

"indivisible" statute — i.e., one that "sets out a single . . .

set   of   elements    to   define    a   single   crime" —   we   apply   the

categorical approach.       See Mathis, 136 S. Ct. at 2248.        That means

we see whether the prosecution had to prove that the defendant

used, attempted to use, or threatened to use physical force against

the person or property of another — not whether he actually did.

See id.    And because we care only whether the prior crime requires

physical force — not whether his criminal conduct involved physical

                                     - 162 -
force    —    we     focus   on    the    least    forceful   conduct   generally

criminalized under the statute, knowing that there must be a

realistic probability the statute would be used to criminalize the

conduct.       See United States v. Báez-Martínez, 950 F.3d 119, 124

(1st Cir. 2020).         And "physical force" here means "force capable

of causing physical pain or injury" to a person or physical damage

to property.         See Johnson v. United States, 559 U.S. 133, 138-40

(2010) ("Curtis Johnson"); see also Davis, 139 S. Ct. at 2325-26.

              Alternatively, if the prior crime involved a violation

of a "divisible" statute — i.e., one that defines multiple crimes

with    distinct       elements —    we    apply    the   modified    categorical

approach (if the statute simply lists different means of committing

a single crime, then it is indivisible and we use the categorical

approach).         See Mathis, 136 S. Ct. at 2249.         This approach allows

us to look beyond the face of the statute to a limited set of

documents      —    known    as   "Shepard   documents,"      which   include   the

indictment, jury instructions, and verdict forms — to see "what

crime, with what elements," the defendant committed.                      See id.

(discussing Shepard v. United States, 544 U.S. 13 (2005)); see

also United States v. Delgado-Sánchez, 849 F.3d 1, 8 (1st Cir.

2017).       But the approach "serves a limited function," namely, to

"help[] effectuate the categorical analysis" when we are faced

with a divisible statute — in other words, after reviewing the

                                         - 163 -
relevant documents and identifying the specific crime underlying

the defendant's conviction, we must then apply the categorical

approach to that crime to see if it is a crime of violence.            See

Descamps v. United States, 570 U.S. 254, 260 (2013).

            Days after the judge sentenced Dzhokhar — giving him

death on some of the death-eligible counts and various concurrent

and consecutive terms on the remaining counts (including 20 life

terms) — the Supreme Court invalidated the Armed Career Criminal

Act's    similarly   worded   residual   clause   as    unconstitutionally

vague.   See Johnson v. United States, 135 S. Ct. 2551, 2557 (2015)

("Samuel Johnson").      For easy reading, we shorten Armed Career

Criminal Act to "ACCA."         The ACCA's residual clause defined

"violent felony" as any crime punishable by a term of imprisonment

exceeding one year that "involves conduct that presents a serious

potential risk of physical injury to another."              See 18 U.S.C.

§ 924(e)(2)(B).      In tossing out that residual clause, Samuel

Johnson (in brief) found "[t]wo features of the [ACCA's] residual

clause" troublesome:      it "leaves grave uncertainty about how to

estimate the risk posed by a crime" and "about how much risk it

takes for a crime to qualify as a violent felony."          See 135 S. Ct.

at 2557-58 (emphasis added).

            Relying on Samuel Johnson, Dzhokhar moved for a judgment

of acquittal on all of the § 924(c) counts.            He also asked for a

                                 - 164 -
new penalty-phase trial as well.           According to his motion, the

judge had told the jury (without objection) that all of the

"predicate" offenses — malicious destruction of property, for

example, or conspiracies to use a weapon of mass destruction, to

bomb a place of public use, and to maliciously destroy property —

constituted crimes of violence as a matter of law.             But, he noted,

the judge did not say which of § 924(c)'s clauses applied to which

predicate.    Insisting that the government could no longer rely on

the residual clause after Samuel Johnson, he also claimed that

none of the predicates categorically qualified as a crime of

violence under the elements clause.

             Opposing the motion, the government argued first that

Dzhokhar had waived his challenge to the § 924(c) counts by not

raising it sooner.       The government premised this argument on two

theories:     that Dzhokhar had to raise defects in the indictment

before trial and that he had to object to the judge's crime-of-

violence instructions either before or after the judge gave them.

Waiver   aside,   the    government    also    argued   that   the   different

wordings    between     § 924(c)'s    residual    clause   and   the    ACCA's

residual clause made Samuel Johnson's void-for-vagueness analysis

inapplicable to Dzhokhar's case.          And relying on Curtis Johnson,

the government insisted that the predicates qualified as crimes of

violence under the elements clause because they involved the use,

                                     - 165 -
attempted use, or threatened use of violent physical force against

the person or property of another.

            The judge denied Dzhokhar's motion, finding § 924(c)'s

residual    clause     not   impermissibly   vague   and    each   contested

predicate a crime of violence under the elements clause.               In a

footnote, the judge theorized how Dzhokhar may have waived any

argument that the predicates failed to satisfy the elements clause.

But the judge did not resolve the waiver issue because he found no

error.

            During the briefing phase of this appeal, the Supreme

Court    issued   an   opinion   declaring   § 924(c)'s    residual   clause

overly vague.     See Davis, 139 S. Ct. at 2336.          With Davis on the

books, that leaves only one potential path for treating the

predicates as crime-of-violence offenses:         the elements clause, a

provision (as we said) that sweeps in crimes having "as an element

the use, attempted use, or threatened use of physical force," see

18 U.S.C. § 924(c)(3)(A) — i.e., "force capable of causing physical

pain or injury" to a person or physical damage to property, see

Curtis Johnson, 559 U.S. at 140.

                         Basic Appellate Arguments

            On appeal Dzhokhar limits his challenge to five § 924(c)

convictions involving Counts 13, 15, 16, 17, and 18.               Counts 13

and 15 alleged as predicates the malicious destruction of property,

                                   - 166 -
colloquially known as arson, resulting in death (as charged in

Counts 12 and 14, respectively).          See 18 U.S.C. § 844(i).    And

Counts 16, 17, and 18 alleged as predicates conspiracies to use a

weapon of mass destruction, to bomb a place of public use, and to

maliciously destroy property, all resulting in death (as charged

in   Counts   1,   6,   and   11,     respectively).   See   18    U.S.C.

§§ 2332a(a)(2), 2332f(a)(1) and (2), 844(i) and (n).

          In essence, Dzhokhar's position boils down to this.

Arson — the predicate crime for Counts 13 and 15 — fails to satisfy

the elements clause because, first, one can commit the offense by

maliciously destroying "any" property, including one's own and so

does not require as an element that force be used against the

person or property of another, as the elements clause requires;

and second, one can commit the crime with a reckless mental state

but the elements clause demands intentional conduct.              Arguing

further, Dzhokhar contends that the challenged conspiracies — the

predicate crimes for Counts 16, 17, and 18 — fail to satisfy the

elements clause because conspiracies criminalize mere agreements

to commit an act and thus do not necessarily have as an element

the actual, attempted, or threatened use of physical force.

          The government responds, essentially, this way.             It

agrees that malicious destruction of property "simpliciter . . .

is not categorically a crime of violence."         It admits that under

                                    - 167 -
our current precedent "reckless conduct, as opposed to intentional

conduct, cannot constitute the use of force against the person or

property of another."      It accepts that "conspiring to commit a

violent act does not necessarily have as an element the use,

attempted use, or threatened use of physical force."          And it

consents to our vacating of Count 18 — predicated on conspiracy to

commit arson — albeit on grounds different from those offered by

Dzhokhar66 (thus sparing us the need to discuss Count 18 further).

            But the government insists that when the indictment

charges arson as a capital crime, "the jury must find as an

element" at least one of the FDPA's gateway-intent factors — each

of which "requires proof that the defendant engaged in intentional

conduct that directly resulted in a victim's death," meaning he

used a level of force required under the elements clause.67       It

     66 Dzhokhar argues that Count 18 is not a valid predicate
because conspiracy to commit an offense is simply an agreement to
commit an offense, and such an agreement does not always require
the actual, attempted, or threatened use of physical force. But
the government insists Count 18 is invalid because the indictment
did not charge the predicate conspiracy as a capital count.
     67   The gateway-intent factors require proof that the defendant
     (A) intentionally killed the victim;
     (B) intentionally inflicted serious bodily injury that
     resulted in the death of the victim;
     (C) intentionally participated in an act, contemplating
     that the life of a person would be taken or intending
     that lethal force would be used in connection with a
     person, other than one of the participants in the
                             - 168 -
also insists that the death-resulting allegations "independently

require[] proof that the victim was subjected to 'physical force'"

as used in the elements clause.      And it takes a similar approach

with the remaining conspiracy predicates, claiming that the death-

resulting allegations establish the type of force needed to satisfy

the elements clause.

                                Analysis

            The parties spend some time addressing our standard of

review.     Dzhokhar argues for a de novo appraisal, noting that we

typically    evaluate   judgment-of-acquittal   and   crime-of-violence

assessments without giving any deference to the district judge's

views.    See United States v. Santos-Soto, 799 F.3d 49, 56 (1st

Cir. 2015) (judgment of acquittal); United States v. Turner, 501
F.3d 59, 67 (1st Cir. 2007) (crime of violence).        The government

pushes for plain-error review, repeating the waiver arguments it

     offense, and the victim died as a direct result of the
     act; or
     (D) intentionally and specifically engaged in an act of
     violence, knowing that the act created a grave risk of
     death to a person, other than one of the participants in
     the offense, such that participation in the act
     constituted a reckless disregard for human life and the
     victim died as a direct result of the act.
18 U.S.C. § 3591(a)(2)(A)-(D). Because no one argues otherwise,
we assume without deciding that the government is right in saying
that each factor (including (D)) requires intentional conduct.
See also Báez-Martínez, 950 F.3d at 124–28 (holding that the mens
rea required for second-degree murder satisfies the ACCA's
elements clause).
                             - 169 -
made in the district court:    that Dzhokhar had to — but did not —

raise the crime-of-violence issue pretrial or object to the crime-

of-violence instructions either before or after the judge gave

them.

           We think Dzhokhar has the better of this standard-of-

review exchange.   United States v. Cruz-Rivera concluded that a

defendant's judgment-of-acquittal motions preserved his § 924(c)

predicate-offense challenge.      904 F.3d 63, 65 (1st Cir. 2018).

And Cruz-Rivera did so even though the defendant had not moved to

dismiss the indictment or objected to the jury charge instructing

that the at-issue predicate constituted a crime of violence as a

matter of law.   See Br. for Appellee at 10, Cruz-Rivera, 904 F.3d
63 (No. 16-1321), 2018 WL 3035960, at *9-10; Br. for Appellant at

20, Cruz-Rivera, 904 F.3d 63 (No. 16-1321), 2018 WL 3261713, at

*20.    The government tries to downplay the importance of this

decision by saying "Cruz-Rivera . . . did not definitively opine

on" the waiver question because "the government never challenged

the preservation of the claim."    When we give de novo review to an

unpreserved claim because the government failed to argue plain

error to us, we say so.   See, e.g., United States v. Blewitt, 920
F.3d 118, 122 n.2 (1st Cir. 2019) (quoting United States v.

Encarnación-Ruiz, 787 F.3d 581, 586 (1st Cir. 2015)).     But Cruz-

Rivera said nothing of the sort — it only said that the defendant

                               - 170 -
had "preserved this issue below." 904 F.3d at 65.    So de novo

review is called for.

          To the merits then.

          First up is whether Dzhokhar's arson convictions (on

Counts 12 and 14) satisfy the elements clause.    The arson statute

at issue punishes the use "of fire or an explosive" to "maliciously

damage[] or destroy[] . . . any . . . property used in interstate

or foreign commerce or in any activity affecting interstate or

foreign commerce."   18 U.S.C. § 844(i) (emphasis added).   And the

parties agree (or at least do not dispute) that "maliciously" there

includes both intentional and reckless acts.   See generally United

States v. Grady, 746 F.3d 846, 848-49 (7th Cir. 2014) (adopting

this definition and collecting circuit cases doing the same).

          Our caselaw says that recklessness does not suffice the

ACCA's materially identical elements clause.     See Báez-Martínez,
950 F.3d at 126 (discussing our bright-line rule that "reckless

conduct bereft of an intent to employ force against another falls

short of the mens rea required under" the ACCA (emphasis removed

and citation omitted)).68   And our caselaw routinely uses decisions

     68 To give a rough sense of our caselaw's evolution:       The
Supreme Court has found recklessness sufficient to count as a crime
that "has, as an element, the use or attempted use of physical
force" under 18 U.S.C. § 921(a)(33)(A) — a statute barring persons
convicted of a "misdemeanor crime of domestic violence" from
possessing a gun. See Voisine v. United States, 136 S. Ct. 2272,
2280 (2016). Voisine said "use" refers to "the act of employing
                              - 171 -
interpreting the ACCA's elements clause in construing § 924(c)'s,

see Taylor, 848 F.3d at 491 — no surprise, since both clauses

encompass "the use, attempted use, or threatened use of physical

force against the person . . . of another," compare 18 U.S.C.

§ 924(e)(2)(B)(i),     with id.   § 924(c)(3)(A).     Which    perhaps

explains   why   the   government   concedes   that   crimes    requiring

something." Id. at 2278 (quotation marks omitted). So, Voisine
held, the "use of physical force" requires "volitional" but not
"knowing or intentional" conduct. See id. at 2279-80. Voisine,
though, left undecided whether this statutory interpretation
should apply in other contexts. See id. at 2280 n.4.
     On the heels of Voisine, we decided Bennett v. United States,
868 F.3d 1 (1st Cir. 2017). Bennett noted that the ACCA requires
a use of physical force "against the person of another," while the
statute in Voisine requires a use of physical force without the
"against the person of another" jargon.      See 868 F.3d at 18.
Bennett   reasoned   that   "against"   may  require   that   "the
perpetrator . . . knowingly or purposefully . . . caus[e] the
victim's bodily injury." Id. But Bennett also found compelling
the possibility that "against" does not change Voisine's analysis.
Id. at 18-20. Finding a "grievous ambiguity" concerning whether
recklessness suffices under the ACCA's elements clause, Bennett
invoked the rule of lenity to hold in the defendant's favor that
recklessness did not suffice. Id. at 23 (quotation marks omitted).
We withdrew Bennett after the defendant died.      See Bennett v.
United States, 870 F.3d 34, 36 (1st Cir. 2017) (per curiam). But
we adopted its reasoning in a later case. See United States v.
Windley, 864 F.3d 36, 37 n.2 (1st Cir. 2017) (per curiam).
     The government believes that we decided these cases wrongly.
The Supreme Court granted certiorari to resolve a circuit split
regarding whether a crime involving "ordinary recklessness can
satisfy the ACCA's [elements] clause." Báez-Martínez, 950 F.3d at
125 n.5. The Court dismissed certiorari after the petitioner died,
see Walker v. United States, 140 S. Ct. 953 (2020), but the Court
recently granted certiorari in another case to address the same
issue, see United States v. Borden, 769 F. App'x 266 (6th Cir.
2019), cert. granted, 140 S. Ct. 1262 (2020).
                                - 172 -
recklessness, as opposed to intent, do not qualify as crimes of

violence under § 924(c)'s elements clause — at least under existing

circuit precedent.

            Our caselaw is also clear about what happens next.

Applying the minimum-conduct rule (as a reminder, the elements-

based    approach    focuses        on   "the     least   culpable   conduct"

criminalized, Báez-Martínez, 950 F.3d at 124), we must presume

that Dzhokhar acted with recklessness, see Taylor, 848 F.3d at

492.    So — as counterintuitive as it might first seem — his arson

convictions are not crimes of violence for purposes of § 924(c)'s

elements clause.

            And   none   of   the    government's    responses   alters   this

conclusion.

            The   government    argues     that    "[w]here . . .    arson   is

charged as a capital offense, the jury must find as an element at

least one of the four 'gateway' special intent factors" in the

FDPA.   These factors, says the government, require proof that the

defendant intentionally engaged in conduct that resulted in a

victim's death and thus proof that he "intentionally used force

sufficient to kill the victim."

            This aspect of the government's response overlooks that

the gateway factors are drawn from the FDPA, not § 844(i) itself.

Under either the categorical or modified categorical approach, we

                                     - 173 -
generally look to the statute of conviction to determine the

elements of the crime.         See, e.g., Mathis, 136 S. Ct. at 2248.

And nowhere in § 844(i) does there appear an intent element.            The

government has pointed us to no authority suggesting that we can

look beyond the statute of conviction to an unrelated statutory

scheme — like the FDPA — to add elements to a crime for these

purposes.       See    Taylor, 848 F.3d   at   491   (explaining   that

"'[e]lements' are the 'constituent parts' of a crime's legal

definition" (alteration in original) (quoting Mathis, 136 S. Ct.

at 2248)).     To convict Dzhokhar on the arson offenses (Counts 12

and 14) — the predicates for the contested § 924(c) counts (Counts

13 and 15) — the jurors did not have to find any of the gateway-

intent factors.        Instead, they could convict even if he acted

recklessly    rather    than   intentionally.      Had   the   penalty-phase

jurors not found the gateway factors proven beyond a reasonable

doubt as to the arson charges, Dzhokhar could not have gotten a

judgment of acquittal on those counts (Counts 12 and 14); indeed,

the indictment on those two counts does not reveal on its face

that the government had to prove intent. Surely then those factors

cannot be elements of the arson predicates.

             The government next contends that the death-resulting

allegations in Counts 12 and 14 provide an independent basis for

us to conclude that the arson predicates satisfy § 924(c)'s

                                  - 174 -
elements clause.    But even assuming without deciding that the

death-resulting allegations are elements (the parties fight over

whether they are), we know the minimum conduct necessary to commit

arson resulting in death is still recklessness.     See generally

United States v. Gullett, 75 F.3d 941, 947-48 (4th Cir. 1996)

(deeming evidence of malice sufficient to convict the defendant of

violating the arson statute, § 844(i), specifically rejecting his

argument that the jury had to find that he intended to damage the

property). As we will discuss shortly, the fact that death results

(when included as an element of the statute of conviction) may

indicate the application of violent force.      But it does not

necessarily involve the intentional application of physical force

(i.e., a "use" in the language of the elements clause) as our

caselaw requires.   See Bennett v. United States, 868 F.3d 1, 7–9

(1st Cir. 2017) (holding that recklessly causing bodily injury

does not constitute the "use . . . of physical force against the

person of another"), opinion withdrawn as moot, 870 F.3d 34, 36

(1st Cir. 2017), reasoning adopted by United States v. Windley,

864 F.3d 36, 37 n.2 (1st Cir. 2017).   So the government's second

basis for affirming these contested § 924(c) counts (Counts 13 and

15) is not compelling either.69

     69 Given our analysis, we need not address Dzhokhar's
alternative claim: that the arson convictions cannot be predicates
because § 844(i) punishes the destruction of one's own property,
                             - 175 -
             Next up is whether Dzhokhar's conspiracy convictions (on

Counts   1   and   6)   satisfy   the    elements      clause.       Recall   that

prosecutors predicated the relevant § 924(c) counts (Counts 16 and

17) on his allegedly conspiring to use a weapon of mass destruction

(Count 1), see 18 U.S.C. § 2332a(a)(2), and to bomb a place of

public use (Count 6), see id. § 2332f(a)(1) and (2), each resulting

in death.     Section 2332a(a)(2) criminalizes anyone "who, without

lawful authority, uses, threatens, or attempts or conspires to

use, a weapon of mass destruction . . . against any person . .                   .

within the United States," provided the "threat, attempt, or

conspiracy[] would have affected interstate or foreign commerce."

Section 2332f(a)(1) applies to anyone who "unlawfully delivers,

places, discharges, or detonates an explosive . . . in, into, or

against a place of public use . . . with the intent to cause death

or serious bodily injury, or . . . with the intent to cause

extensive    destruction    of    such   a   place."      Section 2332f(a)(2)

prohibits      "attempts     or     conspirac[ies]         .     .     .      under

[§ 2332f(a)(1)]."       And "if death results" from these crimes, the

statutes provide for punishment "by death or imprison[ment] for

while § 924(c)'s elements clause covers the use of force against
the property of the another. See generally PDK Labs. Inc. v. DEA,
362 F.3d 786, 799 (D.C. Cir. 2004) (Roberts, J., concurring)
(explaining that "if it is not necessary to decide more, it is
necessary not to decide more").
                                   - 176 -
any term of years or for life."      See id. § 2332a(a); see also id.

§ 2332f(c).

           Helpfully,     the   parties      agree     that      the     at-issue

convictions     concern   conspiracies      to   use   a    weapon       of    mass

destruction and to bomb a place of public use (not attempts to do

either crime, for example), with death resulting.70                    Our "task"

then "is to compare" the elements of those conspiracies "to the

definition of a 'crime of violence' in the force clause."                       See

United States v. García-Ortiz, 904 F.3d 102, 106 (1st Cir. 2018)

(using the categorical approach where the parties "agree[d]" that

the   defendant's   "conviction    concerned     Hobbs     Act   robbery      (not

extortion)").    So the question is whether the at-issue conspiracy

offenses have as an element the use, attempted use, or threatened

use of "violent [physical] force — that is, force capable of

causing physical pain or injury to another person."                    See Curtis

Johnson, 559 U.S. at 140; see also Moncrieffe v. Holder, 569 U.S.
184, 190-91 (2013) (requiring courts to consider whether the least

serious form of the relevant offense meets that standard).                    If it

does, then the relevant conspiracies qualify categorically as

crimes of violence — if not, then not.

      70The government's brief does quote § 2332f(a)(1), which
again punishes the bombing of a place of public use (we simplify
slightly here). But the government tailors its arguments to the
conspiracy context, which of course implicates § 2332f(a)(2).
                                  - 177 -
           A conspiracy is — as the parties concur — a knowing

agreement between two or more people "to commit a crime, intending

that the underlying offense be completed."         See United States v.

Ledée, 772 F.3d 21, 32 (1st Cir. 2014).          The crime of conspiracy

is the agreement rather than the completed offense.         See Iannelli

v. United States, 420 U.S. 770, 777 (1975) (explaining that

"[c]onspiracy is an inchoate offense, the essence of which is an

agreement to commit an unlawful act").71     So "conspiracy's elements

are met as soon as the participants have made an agreement."

Sessions v. Dimaya, 138 S. Ct. 1204, 1219 (2018). Thus — to borrow

a line from the government's brief (emphasis omitted) — "simply

conspiring to commit a violent act does not necessarily have as an

element the use, attempted use, or threatened use of physical

force," meaning "most conspiracies to commit what would otherwise

be crimes of violence are not categorically crimes of violence

under" § 924(c)'s elements clause.

           But the "death results" element changes things.          Báez-

Martínez says that any crime for which "death results" (or any

serious   bodily   injury   results)   is   an    element   automatically

satisfies the ACCA's "violent force" requirement. 950 F.3d at

     71 Inchoate means "[p]artially completed or imperfectly
formed; just begun." See Inchoate, Black's Law Dictionary (11th
ed. 2019).
                                - 178 -
132.   So while most conspiracies are not crimes of violence,

conspiracies that are categorically defined to result in death are

(assuming the other requirements like intent are satisfied).       And

here, the statute makes "death results" an element of the crime.

Section 2332a says that "if death results" from a violation of the

at-issue conspiracy statutes, the punishment may be up to life in

prison or death. 18 U.S.C. § 2332a(a). Section 2332f incorporates

this penalty scheme. Id. § 2332f(c).

          Dzhokhar argues that "death results" is not an element

of § 2332a or § 2332f under the crime-of-violence categorical

approach because, like the FDPA gateway factors, that element need

only be proven to the jury at the penalty phase.       But unlike the

FDPA gateway factors, the "death results" element appears in the

statute of conviction itself (or is incorporated into that statute,

for § 2332f).    True, as Dzhokhar suggests, a (guilt-phase) jury

could have convicted him under § 2332a or § 2332f without deciding

that anyone died, and those convictions would stand even if the

(penalty-phase) jury found that no deaths resulted.          But these

statutes, it seems to us, are divisible into two branches:      one in

which there is no "death results" element (and the penalty is up

to life in prison), and one in which "death results" is an element

(and the penalty can be death).       See Mathis, 136 S. Ct. at 2256

(noting   that   "[i]f    statutory   alternatives   carry   different

                                - 179 -
punishments, then under Apprendi they must be elements"). Yet we

know Dzhokhar's conduct falls into the latter branch.   And this we

know from the indictment — which for Counts 1 and 6 says that the

conspiracy resulted in the death of at least one person; and from

the jury's guilt-phase verdict — which found beyond a reasonable

doubt that the conspiracies resulted in at least one death.72    So

under the modified categorical approach, the predicate offenses

(Counts 1 and 6) are crimes of violence.   And thus his convictions

on Counts 16 and 17 must stand.

          Our use of the modified categorical approach here aligns

with the purpose behind that doctrine.   The Supreme Court designed

the categorical and modified categorical approaches to simplify

the types of evidence we can look to in making a crime-of-violence

assessment.   See Taylor v. United States, 495 U.S. 575, 601 (1990)

(recognizing the "practical difficulties and potential unfairness

of a factual approach"); see also Shepard, 544 U.S. at 17.      Were

we to go beyond these Shepard documents, we could find ourselves

     72The judge instructed the guilt-phase jurors that to convict
Dzhokhar on the contested conspiracy counts (Counts 1 and 6), the
government had to prove three elements beyond a reasonable doubt:
first, that he agreed with another to use a weapon of mass
destruction (Count 1) and to bomb a place of public use (Count 6);
second, that he knowingly joined these conspiracies, intending
that the crimes be committed; and third, that these conspiracies
"resulted in the death of a person named in the respective count
of the indictment."
                              - 180 -
lost in a sea of evidence presented at trial to the jury.                 And we

might never be able to tell whether certain facts were proven

beyond a reasonable doubt. But our analysis requires no guesswork,

for (again) the Shepard-approved documents and the text of § 2332a

and § 2332f indicate that at least one person died as a result of

Dzhokhar's involvement in the conspiracy.

            In    a    different      context,   we   have    noted     that     an

indictment's     death-resulting       references     "invoked"     a   statute's

"sentencing regime," increasing "the maximum sentence available,"

and so is "pertinent only to sentencing."                    United States v.

Hilario-Hilario, 529 F.3d 65, 69 (1st Cir. 2008) (emphasis added).

And except for a fact of a prior conviction, any fact that boosts

a crime's maximum sentence or minimum sentence must be established

beyond a reasonable doubt to a jury's satisfaction (unless the

defendant agrees to a bench trial or formally admits the facts).

See Apprendi, 530 U.S. at 490 (maximum); Alleyne v. United States,

570 U.S. 99, 103 (2013) (minimum); see also United States v.

Gonzalez, 949 F.3d 30, 41-42 (1st Cir. 2020).                     See generally

Burrage v. United States, 571 U.S. 204, 210 (2014) (stating that

"[b]ecause the 'death results' enhancement [in 21 U.S.C. § 841(b)]

increased   the       minimum   and    maximum   sentences     to   which      [the

defendant] was exposed, it is an element that must be submitted to

the jury and found beyond a reasonable doubt").               Dzhokhar's reply

                                      - 181 -
brief touches on these points, at least inferentially.             But while

an   additional       sentencing    element —    like    § 2332a's     "death

results" —    would    be   "pertinent   only   to   sentencing"   for   most

purposes, see Hilario-Hilario, 529 F.3d at 69, for purposes of the

modified categorical approach, we think here that it is right to

consider this as an element of the crimes of conviction, see

Mathis, 136 S. Ct. at 2256.73

                                   CONCLUSION

             Having completed our review, the net result is this:          We

reverse Dzhokhar's convictions on Counts 13, 15, and 18, with

directions to acquit.       And we vacate his death sentences on Counts

4, 5, 9, 10, and 14, with directions to hold a new penalty-phase

trial consistent with this opinion and with Local Rule 40.1(k)(1)

of the District of Massachusetts.         But make no mistake:       Dzhokhar

will spend his remaining days locked up in prison, with the only

matter remaining being whether he will die by execution.

                       -Concurring Opinion Follows-

     73Not to put too fine a point on it, the government proved
the death-resulting element beyond a reasonable doubt — something
we know without looking beyond the Shepard documents.

             TORRUELLA, Circuit Judge (Concurring in part, Joining in

part, Concurring in Judgment).      I agree with the lion's share of

the majority's reasoning and join all its holdings.         I regretfully

must write separately, however, to express my disagreement with

its handling and tentative conclusion of Tsarnaev's claim that he

could not receive a fair trial by an impartial jury in this venue.

             Tsarnaev properly raised this issue with our blessing,

and it therefore requires -- and deserves -- a straight answer.

In my view, the district court's rulings on Tsarnaev's motions for

transfer of the trial venue, affirmed on intermediate appeal by

this court and tentatively adopted by the majority, was patently

incorrect.74    Furthermore, the issue of unduly prejudicial pretrial

publicity is likely to recur with more frequency in this modern

day of technology.      If an accused's Fifth and Sixth Amendment

rights are to be other than a hollow platitude, it is imperative

that this court's jurisprudence establish a realistic standard for

cases such as this one, in which a steady stream of information by

way   of   myriad   sources   inundated    an   already   deeply   affected

community.     If this case did not present a sufficient basis for a

74 The denials of Tsarnaev's mandamus petitions further reflect a
long-standing circuit bias on the pretrial publicity issue, which
required a panel of out-of-circuit judges to overcome. Compare
United States v. Casellas-Toro, 807 F.3d 380 (1st Cir. 2015) with
United States v. Moreno-Morales, 815 F.2d 725 (1st Cir. 1987).
                                 - 183 -
change of venue, there are no set of circumstances that will meet

this standard, at least not in the First Circuit.

             Let me be clear that at the sentencing retrial of this

case, if the issue of venue is again raised, Tsarnaev will have to

allege and prove prejudicial circumstances at the time of his

motion, likely nearly a decade after the crime was committed.          But

that is a horse of another color.            The question before us that

must be decided is whether Boston was the appropriate venue for

Tsarnaev's trial in 2015.

                              I.   Discussion

             In denying Tsarnaev's second mandamus petition, the

mandamus majority assured that it "reviewed the entire voir dire

conducted to this point by the [district] court and the parties,"75

and   that   "the   process   ha[d]   been   thorough   and   appropriately

calibrated to expose bias, ignorance, and prevarication."            In re

Tsarnaev ("Tsarnaev II"), 780 F.3d 14, 24-25 (1st Cir. 2015); see

process]    is   working   to    ferret       out   those   jurors    who   should

appropriately be excused for cause"), 26 (declaring that "the

careful     process   employed     by    the    district     court    . . . ha[s]

afforded [it] 'a sturdy foundation to assess fitness for jury

service.'" (quoting Skilling v. United States, 561 U.S. 358, 395

(2010))),    26-28    (describing       the    district     court's   efforts   to

"explore,     and     eliminate,        any    prejudice"      as     "rigorous,"

"extensive," and "careful").            Today, this court reverses course

and finds the district court's juror inquiry lacked adequate

safeguards, a finding with which I fully agree.

             The majority's reason for reaching that conclusion,

however, misses the forest for the trees.                 Although I agree that

jury selection in this case failed to comply with this court's

mandate in Patriarca v. United States, 402 F.2d 314, 318 (1st Cir.

1968), the fact of the matter is that "[n]o amount of voir dire

[could have] overcome th[e] pervasive prejudice" against Tsarnaev

in the Eastern Division of the District of Massachusetts, "no

matter how carefully it [was] conducted."                 Tsarnaev II, 780 F.3d

at 30 (Torruella, J., dissenting).              The district court's denials

of Tsarnaev's motions for change of venue amount to an abuse of

discretion and denied Tsarnaev the right to a fair trial and

sentencing determination.

                                    - 185 -
A.   This Panel Should Address Venue

             To decide this case on Patriarca grounds, the majority

puts its weight on the mandamus majority's expectation that a

searching voir dire would be conducted.           See slip op. at 42, 72.

Yet, this was not the only assurance that drove the mandamus

majority's denial in Tsarnaev II.           That venue-change-denial also

heavily   relied     upon   the   assumption   that,   should     Tsarnaev   be

convicted, he would "have the opportunity to raise a challenge

based on a lack of a fair and impartial jury on direct appeal."
780 F.3d at 18.      "Indeed, that is the customary mechanism by which

such challenges are presented and assessed." Id. at 18-19; see

also id. at 29 ("[M]ost importantly, . . . the petitioner remains

able to raise claims of lack of an impartial jury on direct

appeal.").        Because this "double layer of review is itself a

guarantee    of    due   process,"    the   mandamus   majority    concluded,

Tsarnaev could not make a showing of the "irreparable injury"

necessary to warrant mandamus relief. Id. at 28-29.

             The question of whether venue was proper in the Eastern

Division is a preliminary matter that precedes all others raised

in this case -- be it jury selection, the exclusion of mitigating

evidence, or any evidentiary challenge.           This is so because the

impropriety of venue is a primordial prejudicial error; should a

presumption of prejudice be warranted, the district court should

                                     - 186 -
not have embarked in jury selection (or made any evidentiary

rulings) in the first place.        Cf. Rideau v. Louisiana, 373 U.S.
723, 727 (1963) (finding a presumption of prejudice "without

pausing to examine a particularized transcript of the voir dire");

United States v. Casellas-Toro, 807 F.3d 380, 389 (1st Cir. 2015)

(looking to jury selection only after assuming the presumption of

prejudice is rebuttable).      The administration of justice demands

that the question of venue be resolved.

           Despite claiming not to decide the venue issue, by one-

sidedly laying out the government's arguments as to venue and then

proceeding to find Patriarca error, see slip op. at 54-72, the

majority implicitly and effectively resolves the issue in the

government's favor -- tacitly finding that venue would have been

proper in the Eastern Division had the district court conducted an

adequate voir dire.     For the following reasons, I cannot agree.

B.   Venue in the Eastern Division was Improper

           The physical and emotional wake of the Boston Marathon

bombings, and the events of the following week, flooded the

residents of the Eastern Division with sorrow, fear, and anger.

Few crimes have been as offensive and devastating to an entire

community than those committed by the Tsarnaev brothers.            But for

even the most heinous of offenses, our system of justice demands

vigorous   protection   --   both   in   appearance   and   fact   --   of   a

                                - 187 -
defendant's right to a fair trial and sentencing.             "[T]he right to

jury trial guarantees to the criminally accused a fair trial by a

panel of impartial, indifferent jurors.           The failure to accord an

accused a fair hearing violates even the minimal standards of due

process." Irvin v. Dowd, 366 U.S. 717, 722 (1961) (emphasis added)

(internal quotations marks omitted).

     1. A Presumption of Prejudice was Warranted

             Article III of the United States Constitution instructs

that criminal trials "shall be held in the State where the said

Crimes shall have been committed[.]"            U.S. Const. art. III, § 2,

cl. 3.       The Sixth Amendment further directs that a criminal

defendant be tried by a jury "of the State and district wherein

the crime shall have been committed."           U.S. Const. amend VI.

             Sometimes in tension with this directive is a criminal

defendant's Sixth Amendment right to an impartial jury and Fifth

Amendment promise of fundamental fairness.            One such circumstance

is when "extraordinary local prejudice" will prevent a fair trial

in    the   judicial   district   in   which    the   crime   was   committed.

Skilling, 561 U.S. at 378.        Where these constitutional provisions

collide, Article III's venue dictate must give way.             Accordingly,

"[u]pon     the   defendant's   motion,   the    court   must   transfer   the

proceeding against that defendant to another district if the court

is satisfied that so great a prejudice against the defendant exists

                                   - 188 -
in the transferring district that the defendant cannot obtain a

fair and impartial trial there."      Fed. R. Crim. P. 21(a).

            "The theory of our [trial] system is that the conclusions

to be reached in a case will be induced only by evidence and

argument in open court, and not by any outside influence, whether

of private talk or public print."           Skilling, 561 U.S. at 378

(alteration in original) (quoting Patterson v. Colorado ex rel.

Att'y Gen. of Colo., 205 U.S. 454, 462 (1907) (opinion for the

Court by Holmes, J.)).      Where "pervasive pretrial publicity has

inflamed passions in the host community past the breaking point"

and "permeat[es] the trial setting . . . [such] that a defendant

cannot possibly receive an impartial trial," the district court

must presume local prejudice and transfer the proceeding.           United

States v. Quiles-Olivo, 684 F.3d 177, 182 (1st Cir. 2012); see

also Sheppard v. Maxwell, 384 U.S. 333, 362 (1966) ("Due process

requires that the accused receive a trial by an impartial jury

free from outside influences.").       A presumption of prejudice is

"reserved for those extreme cases where publicity is both extensive

and   sensational   in   nature."    Quiles-Olivo, 684 F.3d   at   182

(internal   quotation    marks   omitted)   (quoting   United   States    v.

Misla-Aldarando, 478 F.3d 52, 58 (1st Cir. 2007)).

            We have once again been tasked with determining whether

the effects of these tragic events, coupled with the unrelenting

                                 - 189 -
pretrial publicity, caused such extraordinary local prejudice that

Tsarnaev   could    not   receive   a   fair   trial   and     sentencing

determination.     In more than forty-five years on the bench at both

the trial and appellate levels, and in my years of practice before

that, I have never borne witness to a case with pretrial publicity

more "extreme" or "extraordinary" than this one -- with so great

a    potential   for   jury   determinations   induced    by     "outside

influence."76    A presumption of prejudice was warranted.

         a. The residents of the Eastern       Division   were    neither
            impartial nor indifferent

           The impact on the residents of the Eastern Division of

the defendant and his brother's week-long reign of terror, and the

extraordinary outpouring of unity and resilience that followed,

quite understandably left the residents of the Eastern Division

76 As an addition to the harm caused by the plethora of pretrial
publicity, upon arrival at the courthouse, and during the jury
selection process and later trial, prospective jurors were met not
only by a building whose front sidewalk was mobbed by all kinds of
press   representatives   and   additaments,   including   several
television towers, but by an atmosphere of intensive security.
The courthouse was patrolled on all sides by numerous
representatives of the Massachusetts State police, the Boston
Police Department, the Federal Protective Service, the U.S.
Marshals, and even the U.S. Coast Guard and Boston Harbor Police,
the last two of whom manned boats on the courthouse's harbor
side. This, of course, is not a comment on the need or adequacy
of the security provided, but rather is meant only to call
attention to a factor that I believe has relevance to the issue of
whether an impartial jury was or could be selected when the issue
of appropriate venue was raised.

                                - 190 -
neither impartial nor indifferent.     The majority opinion has

detailed but a fraction of heart-wrenching destruction, pain, and

suffering inflicted by the Tsarnaev brothers through their crimes.

I do not believe it necessary to further elaborate on these

harrowing details.   Suffice it to say, a detailed read of the

record touches even the most detached of readers.

          Although the impact of the defendant's crimes was felt

nationally and internationally, the destruction was acutely felt

by the residents of the Eastern Division.   The prospective jurors

and their loved ones, and the communities themselves, were all

victims of these disturbing acts of terror.   In addition to those

killed and maimed by the bombings, millions in Greater Boston

witnessed firsthand the carnage at the finish-line, knew someone

directly impacted by the bombings, were ordered to shelter in

place, had their houses searched by law enforcement with weapons

drawn,77 saw their neighborhoods occupied by military personnel,

psychological, and emotional trauma of these events was long felt

locally.     While others around the country may have viewed the

marathon bombings "as an attack on all of America," slip op. at

58, to the residents of the Eastern Division, the Boston Marathon

bombings were an attack on them.79

of Greater Boston rallied together as never before to support each

other.      Immediately after the bombings, residents watching the

marathon worked alongside first responders to treat the injured.80

            Perhaps enhanced by Ortiz's comments, the ubiquitous and

inspiring "BOSTON STRONG" campaign grew rapidly as an impressive

expression of "defiance, solidarity, and caring."84             The blue

background with yellow lettering (borrowing from the colors of the

Boston Athletic Association, the organizers of the Boston Marathon

race) was emblazoned on buildings, fences, fields, and bodies all

over the Greater Boston metropolitan area.       The campaign reflected

a sense of compassion, unity, and recovery much needed in a

community reeling from its upheaval.      See Tsarnaev II, 780 F.3d at

25 n.13 ("[T]he Boston Strong theme [was] about civic resilience

and recovery.").        "BOSTON STRONG" reflected "all of us coming

together as a city," one member of the venire aptly noted.             As

then-Boston    Police    Commissioner   Edward   F.   Davis,   III,   told

They knew that things would never be the same.89           Widely shared

amongst the Eastern Division was a feeling of sorrow, and that

each day "[w]e are all just doing the best we can."90

           Just as the victims of other crimes (and their loved

ones) cannot be "indifferent" or "impartial" for purposes of their

wrongdoer's   trial,   despite   any   declarations   to   the   contrary,

neither here were the residents of the Eastern Division.            Thus,

the Fifth and Sixth Amendments required that they not be seated on

Tsarnaev's jury.

       b. Local pretrial       publicity    was    both   extensive     and
          sensational

  In a district still suffering physical and emotional trauma, the

pretrial publicity enhanced its effects.        Indisputably the volume,

depth, and duration of the media coverage, from the bombings to

Tsarnaev's    capture,   and   well   beyond,   was   nothing   short   of

extraordinary.     Nor can one challenge the sensational nature of

the pretrial publicity -- including the horrific sights and sounds

at the marathon finish line, the ensuing manhunt and lockdown of

a million people, and the removal of a bloodied Tsarnaev from a

boat in Watertown.    This coverage included photographic and video

footage of the crime being committed, maimed victims with bones

protruding from their bodies, and the marathon finish line covered

in blood.     Every moment of the search for the suspects was live-

streamed.     And newspapers and magazines documented Tsarnaev's

confessions (both written in the boat and at the hospital, the

latter of which he gave without the benefits of Miranda warnings,

despite his request for a lawyer, and which thus would not be

offered into evidence).

             Coverage of the marathon bombings and its aftermath

received international attention -- the who, what, where, and when

of the crimes themselves widely covered.          For anyone exposed to

the media spectacle (as 99.7% of the venire was), or anyone with

a smartphone and social media account, the pretrial publicity was

"in a very real sense" the guilt-phase of Tsarnaev's trial.       See

Rideau, 373 U.S. at 726.         For those in the Eastern Division,

however, the media coverage was amplified.      The disturbing images

of maimed victims were broadcast on repeat.91    Many local residents

were confined to their homes during the Governor's lockdown order,

watching live footage of law enforcement scouring the city for the

Tsarnaevs.     After viewing this news coverage, "[a]ny subsequent

court proceedings [about Tsarnaev's guilt] . . . could be but a

hollow formality."     See id.   Indeed, approximately two-thirds of

prospective jurors admitted in court to having concluded that

Tsarnaev was guilty of the charged crimes before seeing a single

piece of evidence.

             The majority adopts the government's view -- unsupported

by the record -- that "this is not a case where almost everybody

locally knows something and very few elsewhere know of it."     Slip

newspapers that belie this assertion.      Despite its recognition of

these articles in its recantation of the facts, see slip op. 24-

analysis.

            Whereas nationwide coverage of the bombing gradually

waned over the following weeks and months, the record reflects

that local media coverage did not.        In Greater Boston, the scope

of that reporting shifted from the facts surrounding the bombing

to a focus on "the city as a whole[,] . . . includ[ing] stories of

the victims and their family and friends, those who bravely risked

their lives to help the victims, and how the entire community came

together." Tsarnaev II, 780 F.3d at 31 (Torruella, J., dissenting)

(footnote omitted).   News sources humanized the local victims and

their families, describing in heart-wrenching and gruesome detail

the emotional and physical struggles of the wounded surviving

victims.    Of the first responders, local newspapers (befittingly)

wrote that "what every firefighter in the city[,] . . . every cop,

every EMS worker did[] . . . was nothing short of heroic."92         Other

journalists   described   how   the   Greater   Boston   community   came

together to mourn the deceased, honor the injured, and begin the

collective healing process.      Many of the articles, (rightfully)

suffering, took to the use of negative descriptors -- including

repeatedly calling him a "monster", a "terrorist," "depraved,"

"callous," "vile," "revile," and the "devil."

           Tsarnaev's guilt preordained, reporters soon focused on

whether Tsarnaev should be put to death -- prior even to the

government's announcement of its intention to seek this outcome.

This   despite    the    fact   that     Massachusetts    abolished      capital

punishment in its state courts in 1984,93 had not executed a

criminal defendant for nearly forty years prior,94 and that the

majority of residents of the Eastern Division had previously

expressed general opposition to the death penalty.95                In this case,

punishment admitted to being conflicted.96                Krystle Campbell's

rethinking her longtime opposition to the death penalty because

"an eye for an eye feels appropriate."        Some of the amputees and

their families were reported to have expressed similar sentiments.

would   "help   everyone   in   their   recovery."   Mayor   Menino,   a

proclaimed opponent of the death penalty, exclaimed, "in this one,

Airport. A banner displaying "BOSTON STRONG" was hung from a hotel

nearby the courthouse, high above the surrounding buildings.               And

the   drum   of   a   cement   truck   parked   directly   across   from   the

courthouse's visitor's entrance was decorated with "BOSTON STRONG"

on one side and "THIS IS OUR CITY" on the other.           A local Teamsters

union continued to distribute "BOSTON STRONG" t-shirts and jackets

to its members.       Fundraising for the victims continued, and local

road races placed the "BOSTON STRONG" logo on shirts distributed

to its participants.

             The district court dismissed the prevalence of these

displays in various ways: although the defense team took the

photographs of the banner and cement truck while jury selection

was ongoing, the district court found the logo's appearances

inconsequential because the cement truck photograph was taken on

a day on which no empaneled jurors attended court,106 and the hotel

banner was not visible at the juror's entrance to the courthouse

or from the jury room107; that the association of "BOSTON STRONG"

"weakened somewhat over time through overuse"; and that (quoting

Skilling, 561 U.S. at 361), "the decibel level of media attention

[had] diminished somewhat."     As jury selection in this case began

less than two years after the bombings, the district court ignored,

however, that the continued displays of "BOSTON STRONG" reflected

an enduring community sentiment which formed the base of the

movement, and a well-deserved pride of accomplishment in the

community's efforts to return to normalcy.108      As one member of the

venire put it, "BOSTON STRONG" was "the spirit of Boston, that

despite whatever happens, . . . we will continue."

             A coming together remarkably similar to this one emerged

in the wake of the 1995 bombing of the Alfred P. Murrah Federal

Office Building in Oklahoma City, Oklahoma, which killed 168

people,   injured   hundreds   more,   and   damaged   numerous   federal

buildings.      See United States v. McVeigh, 918 F. Supp. 1467,

1471-72 (W.D. Okla. 1996). Like "BOSTON STRONG," "Oklahoma family"

became "a common theme" amongst the Oklahoma media and political

leaders, emphasizing "how the explosion shook the entire state,

. . . how the state has pulled together . . . as a family," and

story.'" Id. at 1471.   Finding that the values of due process and

fairness required that the trial of the Oklahoma City bombing

suspects     be   transferred   to   Denver,109   Chief   Judge   Matsch

pertinently described the profound potential for prejudice in this

situation:

             Pride is defined as satisfaction in an
             achievement, and the people of Oklahoma are
             well deserving of it. But it is easy for those
             feeling pride to develop a prejudice . . .
             [t]he existence of [which] is difficult to
             prove. Indeed it may go unrecognized in those
             who are affected by it. The prejudice that
             may deny a fair trial is not limited to a bias
             or discriminatory attitude.    It includes an
             impairment of the deliberative process of
             deductive reasoning from evidentiary facts
             resulting from an attribution to something not
             included in the evidence. That something has
             its most powerful effect if it generates
             strong emotional responses and fits into a
             pattern of normative values.
Id. at 1472 (internal quotation marks and citation omitted).

Similarly, the Supreme Court has noted that "[t]he influence that

could not take place in Oklahoma City, in part because "obtaining
an impartial jury in Oklahoma City would be 'chancy.'" McVeigh,

no further consideration of that venue was necessary. Id. The

lurks   in   an     opinion    once    formed      is   so   persistent       that    it

unconsciously fights detachment from the mental processes of the

average man."       Irvin, 366 U.S. at 727.

             Such was the state of the Eastern Division.                    Amongst an

entire community so deeply affected by these crimes, the "intensity

of the humanization of the victims" by the media, McVeigh, 918
F. Supp. at 1472, the heavy emphasis on grief, and the powerful

portrayals of people struggling to make sense of this calamity,

imprinted     a    pervasive     and    insurmountable         prejudice      in     the

community psyche.       In such circumstances, an individual juror "may

have an interest in concealing his own bias . . . [or] may be

unaware of it."        Smith v. Phillips, 455 U.S. 209, 221-22 (1982)

(O'Connor, J., concurring).             And the unconscious nature of this

impairment makes juror questionnaires and voir dire a poor means

for assessing juror impartiality.            See William H. Farmer, Presumed

Prejudiced, But Fair?, 63 Vand. L. Rev. En Banc 5, 8 (2010).

             The    majority's       "serious    points      against    [Tsarnaev's]

venue-change arguments" lean heavily on the pretrial polling data.

See slip op. at 54-55.           The majority finds this data convincing

because   the      pollster    did    not   "ask    respondents        to   judge    for

themselves whether they are biased[]" and "[i]nstead . . . asked

whether Tsarnaev should get the death penalty."                   Slip op. at 55.

But, even though the pollster did not explicitly ask respondents

                                       - 207 -
if they were biased,110 it is the court's (and the majority's)

dependence on this polling data to decide the venue challenge that

leaves prospective jurors as the judges of their own impartiality.

This is the very problem that the majority takes issue with in its

Patriarca analysis.     See slip op. at 62, 65, 67, 72.    Further, the

data cannot be relied upon to accurately identify local prejudice.

Despite the majority's conclusory claim otherwise, see slip op. at

55, the survey does not -- and cannot -- account for the fact that

the people who are most acutely affected by trauma and persistent

media coverage thereof often lack awareness of the impact this

exposure   has   to   their   decision-making   capacity   in   the   jury

deliberation room -- particularly when they are being asked to

make a decision as high-stakes as the appropriate punishment for

the individual that wreaked havoc on their lives and those of their

neighbors and communities.       See McVeigh, 918 F. Supp. at 1473.

That over 92% of Boston residents admitted in the community poll

that they believed Tsarnaev was "definitely" or "probably" guilty

based on their exposure to pretrial publicity, whereas 25% less

admitted prejudgment in their juror questionnaires, highlights the

inadequacy of survey polling to determine local prejudice in

110 A strange question indeed; most people asked during a vote-
by-mail poll would not likely respond to such a question by stating
that they are "biased," especially because most would not be aware
that they may be so.

circumstances such as existed in the Eastern Division, and the

potential inability of jury selection to sufficiently weed out the

prejudices in this venue.

          This   "impairment    of   the   deliberative   process,"

particularly during a moment such as jury deliberations in a case

of such prominence, is not easily quantifiable.    Again, I invoke

Chief Judge Matsch:

          The possible prejudicial impact of this type
          of publicity is not something measurable by
          any objective standards. . . . [S]urveys are
          but crude measures of opinion at the time of
          the interviews.   Human behavior is far less
          knowable   and   predictable  than   chemical
          reactions or other subjects of study by
          scientific   methodology.     There   is   no
          laboratory experiment that can come close to
          duplicating the trial of criminal charges.

Id.111

          Given the unknowing nature of the prejudicial effect of

inflammatory pretrial publicity on severely afflicted people, see

Irvin, 366 U.S. at 727; McVeigh, 918 F. Supp. at 1472-73, and the

great potential for equivocation by individual jurors impacted by

these outside influences, see Smith, 455 U.S. at 221-22, it must

be given little weight that polling data showed somewhat similar

111 I recognize that the district judge's exercise of discretion
in McVeigh does not itself mean that the district court's decision
not to move Tsarnaev's trial was necessarily an abuse. But, given
its similarity to our situation, it certainly cannot be ignored in
the exercise of our review.
                               - 209 -
(but still lower) numbers regarding a proclivity for the death

penalty in Springfield and New York than in Boston.112

            The   majority    next   declares,   again        without   record

support, that "most of the publicity was true."           Slip op. at 55.

Much of the local publicity included not only factual narrations

of the events that transpired but also commentary and opinions,

such   as   the   aforesaid    references   to   him     as     a   "monster,"

"terrorist," "evil," the "devil," and other similar derogations.

I have no doubt that other media sources either did the same or

quoted others who did.113     Even if these are appropriate adjectives

to describe Tsarnaev, this does not mean the descriptors did not

have a prejudicial impact on the venire's ability to make decisions

based solely on what was presented in court.           See, e.g., Rideau,
373 U.S. at 725-26 (televised confession was factual but prejudicial).

112 The majority strangely and misleadingly finds convincing that
"fewer [survey] respondents preferred life without parole in
Springfield (45.4%) than in Boston (51.2%)." See slip op. at 55.
But the lower percentage of Springfield respondents preferring
life without parole does not mean that a higher percentage of
Springfield respondents preferred the death penalty than in
Boston.   In fact, the opposite is true: a higher percentage of
respondents preferred the death penalty in Boston than in
Springfield, Manhattan, or Washington, D.C. The fact that fewer
respondents in Springfield stated a preference for life without
parole than in Boston is explained by the fact that a higher
percentage of respondents in Springfield (19.5%) refused to
provide an answer to the question than in Boston (12.1%).
113  See, e.g., Planas et al., supra n.103 (calling Tsarnaev a
"punk" and a "bad guy").
                                 - 210 -
The same is true of the reports that public officials believed

Tsarnaev should die, and the detailed chronicling of the pain of

the survivors and decedents' families.              These reports may reflect

reality, but the media's emphasis of these topics carried a

significant risk of disturbing potential jurors' impartiality.

This publicity was anything but "trivial."

             I do not mean to imply that every juror was being

disingenuous or deceitful in their self-declared impartiality.

But our "[t]rust in their ability" to disregard this prejudicial

information      "diminishes    when   the    prior       exposure   . . . evokes

strong emotional responses or such an identification with those

directly affected by the conduct at issue that the jurors feel a

personal stake in the outcome."            McVeigh, 918 F. Supp. at 1473.

Our own biases often go unrecognized or ignored.                     The risk of

implicit biases in this case was impermissibly high, particularly

with the defendant's life on the line.

           d. The "Skilling" factors

             The    majority    suggests     that    an    application      of    the

eponymous Skilling factors counsels against an abuse-of-discretion

finding. See slip op. at 56-58. As I noted in my mandamus dissent,

I   find   the     comparison   between    this     case   and   Skilling    to   be

inapposite.        See Tsarnaev II, 780 F.3d at 42 (Torruella, J.,

dissenting).       Skilling involved "neither heinous nor sensational"

                                    - 211 -
facts, but rather white-collar economic crimes which impacted only

a minority of potential jurors in the Eastern District of Texas.
561 U.S. at 370, 384 (noting that the "jurors' links to Enron were

either nonexistent or attenuated"); see also United States v.

Skilling, 554 F.3d 529, 560 n.47 (5th Cir. 2009), aff'd in part,

vacated in part, 561 U.S. 358 (2010) (noting an opinion poll that

found that one in three Houstonians knew someone harmed by what

happened at Enron).    Contrast that with the facts in this case: a

terrorist attack with explosives at the iconic Boston Marathon; a

widespread and crowdsourced search for the suspects; the execution

of a police officer; a carjacking; a shootout on a suburban street;

a shelter-in-place order; a televised manhunt; a standoff around

the Watertown boat; the televised removal of a bloodied defendant

from that boat; and a traumatized Eastern Division.

          Even assuming arguendo the applicability of the Skilling

factors to this terrorism case, I would find that they weigh in

Tsarnaev's favor.     First, the Skilling Court looked to the "size

and characteristics of the community in which the crime occurred,"

noting that Houston was the fourth most populous city in the United

States with a "large, diverse pool of potential jurors." 561 U.S.

at 382. Boston is not even in the top twenty in terms of population

size. See United States Census Bureau, Population Division, Annual

                               - 212 -
Estimates of City and Town Population Totals: 2010-2019 (May 21,

2020).

             Equally if not more important are the characteristics of

the community.       See Casellas-Toro, 807 F.3d at 387 (commenting that,

although Puerto Rico has a population of approximately three million,

it is an "insular community that is highly susceptible to the impact

of local media" and "seem[s] to be a small island" (internal quotation

marks and citation omitted)).       The Court in Skilling noted that only

12.3% of Houstonians were able to name Skilling as an Enron

executive they believed guilty of crimes, and 43% had never heard

of   him.     This    case   is   again   easily   distinguishable.   Here,

"Tsarnaev and the Boston Marathon bombings [were] one and the

same."      Tsarnaev II, 780 F.3d at 42 (Torruella, J., dissenting);

see also Def.'s Reply to Opp'n to Mot. to Change Venue at 4, United

States v. Tsarnaev, No. 13-cr-10200-GAO (D. Mass. filed Aug. 7,

2014), ECF No. 461-23 (showing that approximately 90% of survey

participants in Boston recognized the name Dzhokhar Tsarnaev, as

opposed to 58% in Springfield, MA, 44 % in Manhattan, and 34% in

Washington, D.C.).       For instance, 99.7% of the voir dire had been

exposed to pretrial publicity about the case as every local news

sources reported about it, and two thirds admitted in their juror

questionnaires that they believed Tsarnaev to be guilty.

                                    - 213 -
            Moreover,     terrorism    targets       the   very   fabric    of    the

community, seeking to tear it apart.            We should thus be especially

sensitive to the community response here as being indicative of

its sense of communal victimhood -- a marker perhaps of its

tightness    as    a   judicial   division.       The      Greater   Boston      area

"band[ed] together"114 in response to this crisis, a "close-knit

place" where "we grieve for [our neighbors]."115                  At that moment,

the Eastern Division was "BOSTON STRONG."116

            Second,     the   news   stories    in    Skilling     "contained      no

confession or other blatantly prejudicial information." 561 U.S.

at 382.     This case involved both.           Not only did the media print

Tsarnaev's message in the boat admitting his crimes, it also

reported information about his non-Mirandized hospital confession

to the FBI.       The news stories also contained blatantly prejudicial

opinions that Tsarnaev should die.

116 My intention is not to cast the "BOSTON STRONG" campaign in a
negative light.    Quite the opposite, the community's recovery
efforts have my highest admiration.
                                     - 214 -
          Third, the Skilling Court looked to the media attention

surrounding Skilling's crime and trial, noting that "the decibel

level . . . diminished somewhat" over the four years between

Skilling's crime and his trial.    Here, although there was a slight

diminution   of   pretrial   publicity    over   the   twenty-one   months

between the bombings and the commencement of jury selection, the

reporting continued to be omnipresent.117

117 The majority finds the time that elapsed between the bombings
and Tsarnaev's trial to be "closer in magnitude to the four years
in Skilling (a point cutting against a venue change) than the two
months in Casellas-Toro (a point favoring a venue change)." Slip
op. at 57.      But the majority misconstrues our precedents.
Casellas's trial did not occur two months after his crime was
committed, but rather two and a half months after the major event
that kept him in the media spotlight -- his televised sentencing
for the murder of his wife. Casellas-Toro, 807 F.3d at 383. Like
Tsarnaev, Casellas allegedly lied to the FBI almost two years prior
to his trial for that crime. Id. at 382 (noting that Casellas
made a false report to the FBI on June 17, 2012), 384 (stating
that voir dire began on April 7, 2014).
Like Casellas, Tsarnaev remained a focal point for the media since
he committed these crimes. Several well-publicized events ensured
that he remained at center stage. In January 2014, the government
announced that it would seek the death penalty, which drew an
enormous media response.       In April 2014, on the one-year
anniversary of the marathon bombings (the week preceding the 2014
running of the Boston Marathon -- which itself garnered
extraordinary attention), the City of Boston held a ceremony to
pay tribute to the Boston Marathon bombing victims.      The event
featured local and national politicians, clergymen, and the
victims and their families. Amongst the attendees (and speakers)
was Vice President Joe Biden.      See John R. Ellement & Martin
Finucane, At Tribute, Marathon Bombing Victims, Survivors Honored,
Boston          Globe           (Apr.          15,          2014),

                                - 215 -
           Finally, the Skilling Court looked to the jury verdict,

finding that the jury's not-guilty findings on nine of the twenty-

eight counts in the case "yielded no overwhelming victory for the

government." 561 U.S. at 375, 383.          Here, because Tsarnaev's

counsel   admitted   Tsarnaev's    guilt    during   opening   and   closing

statements, the jury verdict finding Tsarnaev guilty on all thirty

counts neither supports nor refutes a presumption of impartiality.

The focus on Tsarnaev continued into the next year.       In early
January 2015, gunmen attacked the Paris office of satirical
newspaper Charlie Hebdo. The media took the opportunity to draw
comparisons between that attack and the Boston Marathon bombings.
See, e.g., Kevin Johnson, Paris and Boston Attacks Pose Striking
Parallels,       USA        Today,       Jan.        9,       2015,
http://www.usatoday.com/story/news/nation/2015/01/08/paris-
boston-attacks/21445461/ (last visited July 10, 2020). That same
month, pictures went viral of a man clearing snow off of the Boston
Marathon finish line following a blizzard.        Eastern Division
residents hailed him as a "hero." Anastasia Williams & Michele
McPhee, Blizzard Mystery Solved: Man Who Shoveled Marathon Finish
Line     Revealed,      ABC      News     (Jan.     28,      2015),
https://abcnews.go.com/US/boston-blizzard-mystery-solved-man-
shoveled-marathon-finish/story?id=28550626 (last visited July 10,
2020). Also that month, Tsarnaev's friend pled guilty to charges
related to the destruction of evidence in this case and lying to
the FBI. See, e.g., Milton J. Valencia, Tsarnaev Friend to Plead
Guilty,       Boston       Globe       (Jan.       13,       2015),

hearing-for-friend-boston-marathon-
bombers/SPbRARYlkYS5XYJMrZNFcM/story.html (last visited July 10,
2020).
Finally, on the first morning of jury selection, the press reported
that Tsarnaev unsuccessfully offered to plead guilty in exchange
for the government's agreement not to seek the death penalty. See,
e.g., Evan Perez, Boston Bombing Trial Lawyers Fail to Reach Plea
Deal,            CNN           (Jan.           5,            2015),
https://www.cnn.com/2015/01/05/politics/dzhokhar-tsarnaev-trial-
plea-deal-fails/index.html (last visited July 10, 2020).
                                  - 216 -
See, e.g., Luong v. State, 199 So. 3d 139, 148 (Ala. 2014) ("[I]n

light of the facts of this case, in particular Luong's admission

that he threw each of his children off the bridge, the fact that

Luong was not acquitted of any of the charged offenses does not

either   support   or   rebut   a   presumption   of   jury   bias    or

impartiality.").

          The majority's comparison of the nine acquittals in

Skilling to Tsarnaev's jury's decision to recommend death for six

of the seventeen death-eligible counts is mind-boggling.      See slip

op. at 57-58.   There is a monumental distinction between the full

acquittals in Skilling -- resulting in no punishment for that

defendant, and this jury's decision about which of the two most

extreme punishments in our criminal justice system to recommend

for each count.    The jury's decision to recommend that Tsarnaev

receive six death sentences and serve eleven life sentences,

instead of recommending that Tsarnaev be killed on seventeen

separate counts, does not indicate a lack of prejudice.       Far from

it.   A criminal defendant can only be put to death once.            The

Supreme Court has noted that the decision of whether to recommend

a death sentence "is mostly a question of mercy."      Kansas v. Carr,

136 S. Ct. 633, 642 (2016).     As Tsarnaev points out, "six separate

death sentences can hardly be considered an act of mercy such as

                                - 217 -
to establish that jurors were either unaffected by the pretrial

publicity or willing to ignore the community sentiment."

            Tsarnaev was entitled to a presumption of prejudice.

  2. The Government Cannot Overcome the Presumption of Prejudice

            The parties quarrel over whether the presumption of

prejudice is rebuttable.      In Casellas-Toro, this court assumed

without deciding that the presumption was rebuttable, and I follow

the same track. 807 F.3d at 388-90.        Yet, even under this

assumption, the government cannot prevail.

            The government argues that it can rebut that presumption

by showing that the district court was able to ascertain the

effects of the potential jurors' exposure to extensive pretrial

publicity and excuse those that were incapable of setting any

prejudice aside.    Not so.   As today's majority has explained, by

refusing to ask prospective jurors content-specific questions

about what they had read and heard, the district court was unable

to identify biases or prejudices that may have resulted from that

exposure.     See Patriarca, 402 F.3d at 318.       The district court

relied on the venire's self-declarations of impartiality, an error

of law and an abuse of discretion.

            The government also cannot show that the district court

seated an impartial jury because the district court failed to

investigate    Tsarnaev's   "colorable"   and   "plausible"   claims   of

                                - 218 -
juror-misconduct. When a defendant raises such a claim, regardless

of   timing,   the   district      court     has    the   "unflagging     duty"    to

investigate.    See United States v. French, 904 F.3d 111, 117 (1st

Cir. 2018), cert. denied sub nom. Russell v. United States, 139
S. Ct. 949 (2019) (quoting United States v. Zimny, 846 F.3d 458,

464 (1st Cir. 2017)).         The district court need not hold a full

evidentiary    hearing,      but   it   must       fashion   and     "even-handedly

implement . . . a sensible procedure reasonably calculated to

determine whether something untoward had occurred."                   United States

v. Paniagua-Ramos, 251 F.3d 242, 249-50 (1st Cir. 2001).                          The

court's procedural discretion does not include a refusal to conduct

any inquiry whatsoever.        Zimny, 846 F.3d at 465.

           But that is precisely what the district court did.

Tsarnaev presented a colorable claim that Juror 286 knowingly

withheld from the court the fact that she posted twenty-two online

comments   mourning    the    death     of   Martin       Richard,    praising    law

enforcement officers (three of whom would later testify at trial),

expressing "BOSTON STRONG" civic pride, and calling Tsarnaev a

"piece of garbage."       Tsarnaev further showed that Juror 286 may

have lied on her juror questionnaire and during voir dire about

sheltering in place with her family.                 And Tsarnaev presented a

second plausible claim that Juror 138 both refused to follow simple

but important court rules and intentionally withheld from the court

                                    - 219 -
his participation in social media conversations.         In the comments

thread on his Facebook page, on which he continued to engage, his

friend urged him to "[p]lay the part so u get on the jury then

send [Tsarnaev] to jail where he will be taken care of."             The

district court's refusal to inquire -- at the government's behest

-- left much to be desired in the way of certainty about these

jurors' impartiality.

             Finally, a review of the seated jurors' questionnaires

and voir dire transcripts confirms that the government cannot rebut

the presumption in this case.    The government admits that there is

a statistically significant correlation between the prospective

jurors' media exposure and their opinions to guilt, and ten of the

twelve seated jurors had been exposed to "a moderate amount" or "a

lot" of publicity.      Prior to trial, three of the twelve voting

jurors admitted to having predetermined Tsarnaev's guilt, and

another two stated that they believed Tsarnaev participated in the

bombings.    See Juror 83: "obviously he was involved in something";

Juror 229: "[f]rom the media" "I suppose that we knew that he was

involved";     Juror 349: marked on juror questionnaire belief that

Tsarnaev was guilty, and stated on voir dire that from "so much

media   coverage"    "anybody   would     think   that   [Tsarnaev   was

involved]"; Juror 395: marked on juror questionnaire belief that

Tsarnaev was guilty; Juror 487: marked on juror questionnaire

                                - 220 -
belief that Tsarnaev was guilty, and explained on voir dire that

this belief came from what he had seen on the news.                       Likewise,

three of the six alternate jurors stated that they believed that

Tsarnaev was involved.          See Juror 552: "[F]rom the videos I saw,

it appeared that he was part and parcel of perhaps depositing those

devices"; Juror 567: "I do believe that he was somewhat involved";

Juror 588: "I believe there's some involvement somewhere, but I

don't know what it is."         And, as just discussed, two seated jurors

were at least inconsistent -- if not deliberately untruthful -- in

their responses during jury selection, calling into question their

declarations   that      they    had    not   yet   formed   an    opinion   about

Tsarnaev's guilt.     See Sampson v. United States, 724 F.3d 150, 164

(1st Cir. 2013) ("The voir dire process . . . is frustrated when

a prospective juror is dishonest.             Both the juror's dishonesty and

her   motivation   for    that    dishonesty        may   cast    doubt   upon   her

impartiality.").

           Although all the seated jurors declared that they could

be fair and impartial and decide the case solely on the evidence

presented in court, little weight can be given to such declarations

by community members so impacted by the crimes and the subsequent

pretrial publicity.       "Natural human pride would suggest a negative

answer to [a question of] whether there was a reason the juror

could not be fair and impartial."             United States v. Dellinger, 472

                                       - 221 -
F.2d 340, 375 (7th Cir. 1972); see also Irvin, 366 U.S. at 728

("[The] psychological impact requiring such a declaration before

one's fellows is often its father.").       In sum, the government

cannot show that the jury that convicted Tsarnaev and recommended

that he be put to death was impartial.            The government has

therefore failed to rebut the presumption of prejudice.

C.   Harmless as to Guilt, Not as to Sentencing

           I agree with the majority that the district court's abuse

of discretion was harmless as to Tsarnaev's guilt but not as to

his sentence.   See slip op. at 72-73, 74 n.33.    Tsarnaev's counsel

admitted his participation in these crimes during both opening and

closing statements, and he does not contend on appeal that he would

not have made these admissions had his trial taken place elsewhere.

Sitting in its expanded role under the Federal Death Penalty Act,

18 U.S.C. §§ 3591-99, a sentencing jury was required "to make a

moral judgment . . . after consideration of aggravating and

mitigating circumstances" about whether Tsarnaev deserved to live

out his natural life in custody or be killed by the government.

See McVeigh, 918 F. Supp. at 1474.     The question of whether these

aggravating circumstances outweigh the mitigating factors is one

of " mercy" for the sentencing jury.    See Carr, 136 S. Ct. at 642.

           With a jury so intensely impacted by the charged crimes,

and so exposed to inflammatory pretrial publicity -- including

                              - 222 -
reports detailing the extreme anguish of their neighbors and

repeated calls for Tsarnaev to be sentenced to death -- I cannot

say with any degree of certainty that the jurors did not possess

a "predilection toward that penalty."             McVeigh, 918 F. Supp. at

1474.

           "With his life at stake, it is not requiring too much

that [a criminal defendant] be tried in an atmosphere undisturbed

by so huge a wave of public passion . . . ."             Irvin, 366 U.S. at

728.    The government cannot show that the district court's abuse

of   discretion   was   harmless    beyond    a   reasonable   doubt   as    to

Tsarnaev's sentence.     See 18 U.S.C. § 3595(c)(2), (c)(2)(C).             For

this reason, I agree that Tsarnaev's death sentences must be

vacated   and   the   case    remanded   to   the   district   court   for    a

sentencing retrial.

                             II. Closing Remarks

           In dissent on Tsarnaev's second mandamus petition, I

expressed my concern that -- in a case having this magnitude of

press coverage and widespread dissemination of information -- a

subsequent jury on retrial would have been exposed to the evidence

(and results) of the first trial and would know that the new trial

was the result of a post-conviction reversal.             Tsarnaev II, 780
F.3d at 46 (Torruella, J., dissenting).             My concern has and very

                                   - 223 -
likely will come to fruition.118       Because the majority rules in the

manner in which it does on the issue of venue, I also maintain

these concerns for future cases. The majority's reasoning cripples

Rule   21(a)   of   the   Federal    Rules    of   Criminal   Procedure   and

undermines the due process and impartiality principles of the Fifth

and Sixth Amendments.      I asked a simple question in 2015 that is

still fitting, and I repeat it today: "If not here, when?" Id. at

45.

118  Again, I make no judgment about whether Boston is a proper
venue for a subsequent sentencing retrial. That determination is
time and place specific and must be made by the district court in
the first instance at that retrial.
