UNITED STATES DISTRICT COURT

FOR THE DISTRICT OF COLUMBIA

UNITED STATES OF AMERICA

v. Criminal Action No. 21-191 (JEB)

RYAN SCOTT ZINK,

Defendant.

MEMORANDUM OPINION

Defendant Ryan Scott Zink was a member of the crowd that stormed the U.S. Capitol on 

January 6, 2021. He is charged with multiple criminal counts related to such conduct. With trial 

fast approaching, the Government has filed three Motions in Limine to preclude certain evidence. 

As it has in the past with identical motions relating to other January 6 defendants, the Court will 

largely grant these Motions. Zink, meanwhile, has filed one Motion to Obtain Certain Evidence 

from the Government and two Motions in Limine to preclude other evidence. The Court will 

largely deny his Motions. 

I. Background and Legal Standard

Zink has been indicted on four counts: Obstruction of an Official Proceeding, in violation 

of 18 U.S.C. § 1512(c)(2) and (2) (Count I); Entering and Remaining in a Restricted Building or 

Grounds, in violation of 18 U.S.C. § 1752(a)(1) (Count II); Disorderly and Disruptive Conduct in 

a Restricted Building or Grounds, in violation of 18 U.S.C. § 1752(a)(2) (Count III); and 

Disorderly Conduct in a Capitol Building, in violation of 40 U.S.C. § 5104(e)(2)(D) (Count IV). 

See ECF No. 6 (Indictment). Both sides have now filed Motions in Limine.

“[M]otions in limine are a means for arguing why ‘evidence should or should not, for 

evidentiary reasons, be introduced at trial.’” Graves v. District of Columbia, 850 F. Supp. 2d 6, 

11 (D.D.C. 2011) (emphasis omitted) (quoting Williams v. Johnson, 747 F. Supp. 2d 10, 18 

(D.D.C. 2010)). They “are ‘designed to narrow the evidentiary issues for trial and to eliminate 

unnecessary trial interruptions.’” Id. at 10 (quoting Bradley v. Pittsburgh Bd. of Educ., 913 F.2d 

1064, 1069 (3d Cir. 1990)). The court has “broad discretion in rendering evidentiary rulings, . . . 

which extends . . . to the threshold question of whether a motion in limine presents an evidentiary 

issue that is appropriate for ruling in advance of trial.” Barnes v. District of Columbia, 924 F. 

Supp. 2d 74, 79 (D.D.C. 2013). 

Although state and federal rulemakers have the prerogative to fashion standards for the 

inclusion of evidence at trial, the Constitution guarantees to criminal defendants the right to a 

“meaningful opportunity to present a complete defense.” Holmes v. South Carolina, 547 U.S. 

319, 324 (2006) (quoting Crane v. Kentucky, 476 U.S. 683, 690 (1986)). This limits courts’ 

ability to impose “arbitrary” rules of evidence, including those that exclude “important defense 

evidence” without serving “any legitimate interests,” or are otherwise “disproportionate to the 

purposes they are designed to serve.” Id. at 324–25 (internal quotation marks omitted). At the 

same time, it falls within a court’s discretion to exclude evidence that is not relevant or whose 

probative value is outweighed by prejudicial factors. Id. at 326; see also id. at 330 (noting that 

evidentiary rules seek to “focus the trial on the central issues by excluding evidence that has only 

a very weak logical connection to the central issues”).

II. Analysis

A. Government Motions

The Government has filed three Motions in Limine. They respectively request that this 

Court restrict: (1) cross-examination regarding the Secret Service’s protocols for protecting highranking executive officials, see ECF No. 52 (Secret Service Motion), (2) arguments and evidence 

regarding inaction on the part of Capitol Police on January 6, 2021, see ECF No. 53 (Law 

Enforcement Inaction Motion), and (3) evidence regarding the precise locations of U.S. Capitol 

Police surveillance cameras. See ECF No. 54 (Camera Motion). The Court addresses each in 

turn.

1. Secret Service Motion

The Government first moves to limit cross-examination of U.S. Secret Service witnesses, 

seeking to exclude testimony about agency protocols for protecting high-ranking executivebranch officials at the U.S. Capitol. See Secret Service Mot. at 2. Out of a concern for national 

security, the Government requests that the questioning of such witnesses be limited to whether 

the Capitol and its grounds were “restricted” on January 6. Id. at 3–4. Zink opposes the 

Government’s request but never offers any substantive argument for why the Court should deny 

this Motion. See ECF No. 57 (Def. Resp.). Because the Government represents that the 

protocols at issue will be beyond the scope of direct examination, the Court will exclude such 

testimony — with the caveat that Defendant may cross-examine within the scope of direct 

testimony should the Government elicit these details there. See United States v. Bru, No. 21-

352, 2023 WL 4174293, at *2 (D.D.C. June 26, 2023) (granting identical motion).

2. Law Enforcement Inaction Motion

The Government next seeks to preclude Zink from (1) raising a defense of entrapment by

law-enforcement officials, and (2) offering any evidence or argument that such officials’ failure 

to act made Defendant’s entry into the restricted area lawful. In the alternative, it asks the Court 

to preclude Zink from offering any evidence or argument concerning alleged inaction by such 

officials “unless the defendant specifically observed or was otherwise aware of such conduct.” 

Law Enforcement Inaction Mot. at 1. In response, Defendant contends that he “has a right to 

introduce evidence and testimony” about “[p]olice refusal to stop, enforce, or otherwise follow 

the law,” since this evidence is “material to the defendants’ defense.” ECF No. 56 (Def. Resp.) 

at 2–3. This Court has previously agreed that precluding all evidence of potential lawenforcement inaction on January 6 before trial “would be premature and should await the 

presentation of evidence at trial.” United States v. Mock, No. 21-444, 2023 WL 3844604, at *3 

(D.D.C. June 6, 2023) (quoting United States v. Carpenter, No. 21-305, 2023 WL 1860978, at *3 

(D.D.C. Feb. 9, 2023)).

The Court will follow this well-trodden path and will not at this time “categorically 

preclude an entrapment-by-estoppel defense.” Id. It will, however, grant the Government’s

alternative request. As in Mock, Defendant here does not — indeed, cannot — argue that 

evidence of police inaction is admissible if he did not observe it. Id. (stating that “unobserved 

behavior” would be “irrelevant under Federal Rule of Evidence 401”). Both sides otherwise 

agree that any evidence of what Zink saw could be relevant to his state of mind. See Law 

Enforcement Mot. at 4. Since Defendant will still be able to introduce evidence of what he 

actually observed, the Court will thus grant the Government’s Motion in part.
5

3. Camera Motion

The Government last moves to exclude information about the precise locations of 

Capitol Police cameras, citing national-security concerns. See Camera Mot. at 2. It also requests 

that, should the defense believe during the course of trial that such locations have become 

relevant, the Court conduct an in camera hearing to resolve the issue. Id. at 5–6. The Court 

recently granted a virtually identical motion with the same proviso in another January 6th trial. 

See Mock, 2023 WL 3844604, at *2. It again finds that balance appropriate here, particularly 

because Defendant has not registered any opposition to this Motion. 

Defendant is unlikely to need to probe the precise placement and scope of individual 

security cameras; general descriptions of each camera’s location, along with the video footage 

each shows, should suffice. The Government, moreover, raises significant national-security 

concerns with identifying camera locations, which would reveal areas not under video 

surveillance and could result in security breaches. See Camera Mot. at 5; see also generally ECF 

No. 54-1 (Declaration of Thomas DiBiase) (explaining security concerns). The Court will 

accordingly preclude the defense from questioning witnesses about the precise location of 

Capitol Police cameras but will allow in camera proceedings should Zink establish that 

presentation of such locations becomes necessary during trial. 

B. Defense Motions

Defendant requests that the United States disclose the identities of certain undercover 

agents who he believes were present at the Capitol on January 6. See ECF No. 51 (Disclosure 

Motion). He also moves in limine to restrict two categories of evidence: 1) signs and other 

barriers that were allegedly not seen by Zink, see ECF Nos. 55 (Signage Motion), and 2) an 
6

aerial photograph of the Capitol. See ECF No. 62 (Aerial Photograph Motion). The Court now 

turns to these Motions.

1. Disclosure Motion

Zink first moves to compel disclosure of “all undercover agents, Antifa activists, and 

confidential human sources within the sphere of the Defendant’s alleged conduct on January 6, 

2021.” Disclosure Mot. at 1. He contends that the identities of these individuals are “crucial” to 

his ability to mount a defense. Id. at 2. The Government objects, arguing that Zink’s Motion has 

no basis in fact and fails to explain how this broadly worded request is relevant to his defense. 

See ECF No. 60 (Government Response to Disclosure Mot.) at 5–7. 

Zink is certainly right that the identity of a potential undercover actor — assuming any 

were present at the Capitol on January 6 — could be exculpatory evidence that the Government 

must disclose under Brady v. Maryland, 373 U.S. 83 (1963). The Government recognizes as 

much, too. See Gov’t Resp. to Disclosure at 7. For example, if an undercover officer or 

informant directed or encouraged Defendant to enter the Capitol, that could well be relevant.

Yet Zink’s Motion never identifies a single individual he interacted with whom he now suspects 

to be an undercover actor. Nor does he explain how the potential presence of “Antifa activists”

is relevant to any defenses he may raise. Instead, Zink’s Motion simply requests the 

identification of any and all undercover Government agents who may have been present at the 

Capitol on January 6, regardless of whether these purported actors could have affected or did 

affect Zink’s conduct or state of mind. This request is far too broad. As a result, the Court will 

deny his Motion subject to reconsideration upon a narrower request.
7

2. Signage Motion

Defendant next moves to prevent the Government from introducing evidence or argument 

regarding (1) signs and other barriers unless it “lays a foundation that Zink actually was in a 

place to witness such features” and (2) the criminal conduct of others. See Signage Mot. at 1–2. 

As is evident from Zink’s own Motion, both sides agree that the first category of evidence is 

admissible so long as the Government provides an adequate foundation — meaning that Zink 

could or should have seen these warnings — at trial. See id. at 1; ECF No. 59 (Government 

Response to Signage Mot.) at 1. The Court will accordingly grant the Motion as to this category.

Zink’s second request is less compelling. Defendant argues that this category of evidence 

should be excluded because it is “irrelevant, confusing, and misleading.” Signage Mot. at 2. He

seems to forget that he was charged with, inter alia, aiding and abetting the obstruction of an 

official proceeding. See Indictment at 1 (Count I). Evidence of the criminal wrongdoing of 

others is not only relevant but crucial to this count, since it is this conduct that Zink is charged 

with aiding and abetting. The actions of other rioters, moreover, are relevant to some of the 

other counts Zink faces. As an example, the rioters’ collective action is relevant to proving that 

Defendant disrupted Congress in violation of 18 U.S.C. § 1752(a)(2), as courts have explained in 

other January 6 cases. See, e.g., United States v. Rivera, 607 F. Supp. 3d 1, 9 (D.D.C. 2022) 

(holding that defendant disrupted Congress by contributing to the overall riot that “collectively 

disrupted Congressional proceedings”). Given what Zink has offered so far, the Court will deny 

this Motion as to this category of evidence.

3. Aerial Photograph Motion

Zink’s final Motion seeks to exclude evidence or argument founded upon an aerial 

photograph of the Capitol grounds with a red line superimposed to show the restricted area’s 
8

perimeter on January 6. See ECF No. 62 (Aerial Photograph Mot.) at 1; ECF No. 66 

(Government Response to Photo Mot.) at 3 (depicting photograph in dispute). Zink contends 

that this piece of evidence is not admissible under the Federal Rules of Evidence because it does 

not depict what actually existed on January 6 and is thus a fake. See Aerial Photograph Mot. at 4 

(“There was of course never any red line painted on the ground around the U.S. Capitol.”). He 

further maintains that the photograph is irrelevant because it was never posted on the Capitol 

grounds. See id. at 7. The Government retorts that the photograph is relevant to establishing the

restricted area and that it helps the jury understand the layout of the grounds. It readily 

concedes, moreover, that no actual red line existed and that Defendant was not aware of the 

photograph itself. See Gov’t Resp. to Photo at 4–5.

 With these caveats, the Court sees no basis to bar the photograph’s admission. To prove 

that Zink violated 18 U.S.C. § 1752(a)(1) (Count II), for instance, the Government must show 

that he entered or remained “in any restricted building or grounds.” 18 U.S.C. § 1752(a)(1). The 

photograph is plainly probative of the boundaries of the restricted area, which the Government 

will have to establish with eyewitness testimony, and whether Defendant ever crossed said 

boundaries on January 6. Title 18 U.S.C. § 1752(a)(2) (Count III) similarly requires the 

Government to establish that Zink engaged in “disorderly or disruptive conduct in, or within . . . 

proximity to, any restricted building or grounds.” Here, too, evidence as to the boundaries of the 

restricted area is highly relevant. The probative value of the photograph thus outweighs any 

potential prejudice or cumulativeness. See Fed. R. Evid. 403. Zink’s conclusory allegations that 

the photograph has been “doctored,” Aerial Photograph Mot. at 4, do nothing to change the 

Court’s conclusion, so it will deny this Motion. The Government, of course, must still 

authenticate the photograph at trial through witness testimony. See Fed. R. Evid. 901(b)(1). 
9

And Defendant will have an opportunity at that time to cross-examine these witnesses about the 

exact contours of the restricted area.

III. Conclusion

The Court, accordingly, will grant the Government’s Motions in Limine regarding Secret 

Service testimony and Capitol camera locations in full and will grant its Motion regarding lawenforcement inaction in part. The Court will also grant in part Defendant’s Motion in Limine

regarding signage and will deny his other Motions. A separate Order so stating will issue this 

day.
