OPINION

DIAZ, Circuit Judge:

Mantel Delance Mubdi entered a conditional guilty plea to drug and firearms offenses, reserving the right to challenge the district court’s denial of his motion to suppress evidence seized during a traffic stop. The district court sentenced him to 300 months’ imprisonment. On appeal, Mubdi contends that the district court erred in denying his motion to suppressbecause the officers who stopped his car did not have probable cause to execute the stop. As an alternative ground forsuppression, he contends that the officers unlawfully prolonged the traffic stop to conduct an open-air canine sniff of his car. Mubdi also argues that the district court erred in increasing his statutory mandatory minimum sentence for the drug offenses based on improper judicial factfinding. Finding no error, we affirm.

I.

A.

On the morning of September 30, 2008, Mubdi was driving a gray Dodge Magnum northbound on Interstate 77 near Statesville, North Carolina. In the car with Mubdi was 2 U NITED S TATES v. M UBDIMarkus Parham. Two Statesville Police Department Officers, Jason York and Phillip Wolfe, were parked in marked police cruisers perpendicular to the highway about ten yards from the right-hand side of the northbound lanes near exit 50. **1** As Mubdi approached the officers, they each visually determined that he was driving above the posted speed limit of fifty-five miles per hour.

York observed a group of cars in front of Mubdi’s car traveling the speed limit, and he noticed that Mubdi was closing in on the group. He tracked Mubdi’s car for about a hundred yards to estimate its speed at sixty-three or sixty-four miles per hour. Wolfe likewise noticed Mubdi’s car gaining on the cars in front of it and pulling away from the cars behind it; he estimated Mubdi’s speed at sixty-five miles per hour. Because of the angle at which the officers were parked, they wereunable to verify their estimates with radar equipment. However, York and Wolfe had both passed a radar certification class that, among other things, provided training on how tovisually estimate the speed of vehicles within a narrow margin of error.

The radar certification course constitutes a minimum of thirty-two hours of training, which includes sixteen hours of"supervised field practice where [officers] learn how to estimate the speed of vehicles and how to operate the radar units properly and to check off and set up the instrument and test for accuracy." J.A. 106. Estimating speed is a mandatory part of the certification process. Officers are trained to estimate speeds both from a stationary position and while in motion. An officer may err on any given estimate (or, indeed, all of them) and still receive certification, provided that he errs in the aggregate no more than forty-two miles per hour over

unit. 3

U NITED S TATES v. M UBDItwelve separate speed estimates (an average margin of error of three and a half miles).

York and Wolfe pursued Mubdi for a few miles as he merged from Interstate 77 onto Interstate 40 heading west. **2** Wolfe passed Mubdi’s car in the left lane in an attempt to see whether its occupants were wearing seatbelts. Mubdi then merged behind Wolfe to pass a truck in the right lane. York,trailing Wolfe and Mubdi, determined that Mubdi was following Wolfe’s patrol car at a distance of no more than two to three car lengths, contrary to the North Carolina Highway Patrol’s recommendation that motorists keep at least a one car length interval per ten miles per hour of speed. **3**

At that point, York activated his blue lights to initiate a traffic stop. After what struck York as "an extended amount of time," id. 163, Mubdi pulled over to the side of the road. York approached the car and asked for Mubdi’s driver’s license and registration. He observed that Mubdi kept his foot on the brake pedal, instead of shifting the transmission to park and releasing the brake. Mubdi handed York a plastic pouch containing his license and a vehicle rental contract. York saw that Mubdi’s "hands were shaking more so than an average person would be shaking for just a routine traffic stop" and

**2** The district court viewed a video recording of the events as captured by York’s dashboard camera.

**3** The North Carolina statute proscribing motorists from following too closely mandates that a "driver of a motor vehicle shall not follow another vehicle more closely than is reasonable and prudent, having due regard for the speed of such vehicles and the traffic upon and the condition of the highway." N.C. Gen. Stat. § 20-152. Notably, the statute is silent as to what constitutes a "reasonable and prudent" distance. York testified thatsuch a distance should be measured either by the Highway Patrol’s recommendation or by the "two second rule" set out in the handbook of the Division of Motor Vehicles for North Carolina drivers. The rule prescribes that
a driver "should allow two seconds between the time the vehicle ahead of [the driver] passes a given point and the time [the driver’s] vehicle reaches that same point." J.A. 160. According to York, Mubdi did not comply with
either standard. 4 U NITED S TATES v. M UBDIthat Mubdi looked scared. Id. 165-66. York asked Mubdi whether he had rented the car, and Mubdi said that he had. In response to York’s questions regarding the purpose ofMubdi’s travel, Mubdi said he was headed to his grandfather’s funeral in Statesville and to his aunt’s house. Mubdi, however, could not tell York his aunt’s name or where she
lived.

York returned to his patrol car to review Mubdi’s license, insurance, and rental contract, and to issue Mubdi a warningticket for speeding and following too closely. The rental contract showed that the car had in fact been rented to LatonyiaBrathwaite, other drivers were explicitly forbidden from driving it, and the car was not permitted to travel outside of Georgia. All told, it took York approximately fifteen minutes to review Mubdi’s paperwork and to issue the warning ticket, a time frame he described as typical. In the interim, Wolfe, along with his drug-sniffing canine, arrived on the scene.

After York completed the warning ticket for speeding and following too closely, he approached Mubdi’s car to issue the citation. He asked Mubdi to roll up the windows, turn off the engine, and step out of the car. Mubdi complied but did notshift the transmission into park. As a result, the car began rolling away before Parham, still seated in the passenger seat, stopped it. York explained the warning ticket and then told Mubdi that Wolfe’s dog would conduct an open-air sniff
around the car.

Captain Jacob Dyson, who arrived on the scene for backup, approached the passenger’s side of the car, knocked on the window, and asked Parham to get out. Parham just looked at him, so Dyson tried the door handle. Parham then rolled down his window, and, when Dyson again asked him to get out of the car, Parham responded, "What for? I don’t have a gun."
Id. 113. When Parham started to reach between his legs to the floorboard, Dyson feared that he was reaching for a firearm and unsnapped his holster. Parham, however, got out of the 5 U NITED S TATES v. M UBDIcar without incident, and both he and Mubdi consented to apat-down for weapons. Shortly thereafter, Wolfe’s dog conducted the open-air sniff and alerted. A search of the car uncovered crack and powder cocaine, as well as two loaded firearms, one under each front seat.

B.

A grand jury returned a superseding indictment charging Mubdi with conspiracy to distribute and to possess with intent to distribute a quantity of cocaine and at least fifty grams of cocaine base, in violation of 21 U.S.C. § 846, possession with intent to distribute a quantity of cocaine and at least fifty grams of cocaine base, in violation of 21 U.S.C. § 841(a), (b)(1)(A), (b)(1)(C), possession of firearms in furtherance of drug trafficking crimes, in violation of 18 U.S.C. § 924(c), and possession of firearms by a convicted felon, in violation of 18 U.S.C. § 922(g)(1) and 18 U.S.C. § 924(e).

Mubdi moved to suppress the drugs and firearms on thegrounds that the officers lacked probable cause to make a traffic stop, lacked reasonable suspicion to prolong the stop to conduct the canine open-air sniff, and conducted an illegal
warrantless search of the car. **4**The district court denied Mubdi’s motion. First, the court found that the officers had probable cause to make the traffic stop because Mubdi was speeding and following too closely. As to the first ground, the court concluded that York and Wolfe were trained in visually estimating vehicle speed and that their testimony regardingMubdi’s rate of speed was credible. After crediting the officers’ testimony and reviewing the video recording of Mubdichanging lanes, the district court further found that the officers had probable cause to stop Mubdi for following too closely.

**4** Mubdi does not press this third ground on appeal. 6 U NITED S TATES v. M UBDIThe court also determined that the duration of the stop was reasonable, particularly given the objective facts that piqued the officers’ growing suspicions. Finally, the court found that the ensuing search of the car was proper on two independent grounds: (1) Mubdi and Parham did not have a reasonable expectation of privacy in the car in that neither of them was an authorized driver on the rental contract, and (2) the officers were justified in searching the car based on the canine alert
and Mubdi’s and Parham’s behavior. **5**

Mubdi entered a conditional guilty plea to all charges, reserving the right to appeal the denial of his suppression motion. At the sentencing hearing, the district court adopted the Presentence Investigation Report setting Mubdi’s offense level at thirty and his criminal history category at IV. Mubdi’s Guidelines sentence was 240 months on the drug charges, due to the government’s filing of a notice of its intent to seek an enhanced punishment under 21 U.S.C. § 851. The district court imposed this sentence and a term of 120 months on the possession of a firearm by a felon charge, to run concurrently.Additionally, the district court imposed a mandatory consecutive sixty-month sentence on the § 924(c) charge, yielding a total term of 300 months’ incarceration. Mubdi timely appealed.

**5** Mubdi challenges both grounds on appeal. With respect to his purported privacy interest as a driver of the rental car, he argues that his case is distinguishable from United States v. Wellons , 32 F.3d 117, 119 (4th Cir. 1994), in which we held that an unauthorized driver of a rental car lacks a reasonable expectation of privacy in the car, notwithstanding that he may have the authorized driver’s permission. In Wellons , the evidence sought to be suppressed was the fruit of an unlawful search. Id. Mubdi contends, however, that the evidence he seeks to suppress is the fruit of an unreasonably long seizure . Mubdi presses that, to the extent that Wellonscontrols this case, we should revisit its holding and reach a contrary conclusion. Because we agree with the district court that the canine alert and Mubdi’s and Parham’s behavior alone justified the search, we need not address this separate argument. 7

U NITED S TATES v. M UBDIII.

In considering the district court’s denial of a motion to suppress, we "review the district court’s legal determinations de
novo and its factual determinations for clear error." United States v. Kelly , 592 F.3d 586, 589 (4th Cir. 2010). When thedistrict court has denied a suppression motion, we must "construe the evidence in the light most favorable to the government." Id. We are also to "particularly defer to a districtcourt’s credibility determinations, for it is the role of the district court to observe witnesses and weigh their credibility during a pre-trial motion to suppress." United States v. Abu
Ali , 528 F.3d 210, 232 (4th Cir. 2008) (quotation omitted).

A.

Mubdi argues that the officers lacked probable cause tobelieve he was speeding or following too closely. The relevant law on this issue is well settled. Although a traffic stopmay be brief and for a limited purpose, it constitutes a "seizure" under the Fourth Amendment and must "not be ‘unreasonable’ under the circumstances." Whren v. United States

,517 U.S. 806, 809-10 (1996). Generally speaking, "the decision to stop an automobile is reasonable where the police have probable cause to believe that a traffic violation has
occurred." Id. at 810; see also United States v. Branch , 537 F.3d 328, 335 (4th Cir. 2008) ("Observing a traffic violation provides sufficient justification for a police officer to detain the offending vehicle . . . ."). Probable cause exists if, given the totality of the circumstances, the officer "had reasonably trustworthy information . . . sufficient to warrant a prudent [person] in believing that the petitioner had committed or was committing an offense." Beck v. Ohio , 379 U.S. 89, 91 (1964).

1.

Mubdi first argues that there was no probable cause to stop him for speeding, notwithstanding that Officers York and 8 U NITED S TATES v. M UBDIWolfe independently estimated that he was driving eight to ten miles above the posted speed limit.

We have intimated, albeit in an unpublished opinion, that an officer’s visual observation of a driver speeding may alone be sufficient to establish probable cause. See United States v.

Daras , 164 F.3d 626, 1998 WL 726748, at *2 (4th Cir. 1998)(per curiam) (unpublished table decision) ("[T]he Government correctly points out that the officer’s visual estimate is also sufficient, by itself, to support a conviction."); see also
United States v. Wornom , 754 F. Supp. 517, 519 (W.D. Va.1991) (affirming a magistrate judge’s conviction of a defendant for speeding based solely on an officer’s visual speed estimate after radar evidence was suppressed).

But we also recently concluded that "the Fourth Amendment does not allow, and the case law does not support, blanket approval for the proposition that an officer’s visual speed estimate, in and of itself, will always suffice as a basis for probable cause to initiate a traffic stop." United States v. Sowards , No. 10-4133, slip op. at 14 (4th Cir. June 26, 2012). In
Sowards , this same district court denied a motion to suppress evidence seized following a traffic stop of the defendant’s vehicle, finding that the officer’s visual speed estimate (of seventy-five miles per hour in a seventy mile per hour zone) alone established probable cause to initiate the stop. Id. at 7-
8.

We reversed, finding that it was clear error for the district court to discount as immaterial the officer’s obvious difficulty with measurements as it pertained to his ability to estimate the defendant’s speed. Id. at 13. Among other patent errors, the
officer in that case testified that there are twelve feet in a yard, twelve inches on a yardstick, and the number of inches on a yardstick depends on the yardstick. Id. at 12. The officer
nonetheless insisted his estimate was accurate in that he had tracked the vehicle for 100 yards. Because the record showed that the officer was, to put it mildly, measurement-challenged, 9 U NITED S TATES v. M UBDIwe lacked confidence in his visual estimate, particularly given the modest five mile per hour differential between the posted speed limit and the defendant’s alleged speed. Id. at 19.

The Sowardsmajority noted that our starting point in such cases is to determine "whether a vehicle’s speed is estimated to be in significant excess or slight excess of the legal speed
limit." Id. at 14. For significant excesses of the legal speed limit, "the speed differential—i.e., the percentage difference between the estimated speed and the legal speed limit—may itself provide sufficient ‘indicia of reliability’ to support an officer’s probable cause." Id. at 15 (emphasis added). On the other hand,

where an officer estimates that a vehicle is travelling in only slight excess of the legal speed limit, and particularly where the alleged violation is at a speed differential difficult for the naked eye to discern, an officer’s visual speed estimate requires additional indicia of reliability to support probable cause.

Id. at 16. While "[s]uch additional indicia of reliability," the opinion expounded, "need not require great exactions of time and mathematical skill that an officer may not have, . . . theydo require some factual circumstance that supports a reasonable belief that a traffic violation has occurred." Id. at 18.

Sowardsfurther suggested that certain techniques, such as "radar [or] pacing methods," id. at 17, might suffice to corroborate an officer’s visual estimate in cases of slight excesses of the legal speed limit. The majority opinion nevertheless emphasizes, though, that the touchstone of the probable cause inquiry is—as always—reasonableness, and the analysisremains whether the "totality of the circumstances" establishes "the reasonableness of the officer’s visual speed estimate." Id. at 17. **6**

**6** Chief Judge Traxler wrote a vigorous and well-reasoned dissent in
Sowards , contending that the majority incorrectly imposed an iron-clad 10 U NITED S TATES v. M UBDIHere, even assuming that Mubdi was only slightly exceeding the legal speed limit, the record supports the reasonableness of the officers’ visual speed estimates, and thus the decision to conduct the stop. Unlike in Sowards , we have before us two independent and virtually identical estimates as to Mubdi’s speed by officers who were required, as part of aradar certification class, to visually estimate the speed of vehicles within a narrow margin of error. **7**In our view, this tandem evidence alone provides sufficient corroboration to support a finding of probable cause, particularly where the record—again unlike the one in Sowards—does not cast a shred of doubt on the officers’ ability to estimate speed or on the accuracy of their visual estimates.

In sum, we discern no clear error in the district court’s conclusion that Mubdi was speeding, based on its separate factualfindings that York and Wolfe were trained in estimating vehicle speed and that their testimony regarding Mubdi’s rate of

rule prohibiting in every instance a probable cause finding based solely on visual speed estimates where a vehicle is traveling only in "slight excess" of the speed limit. Sowards , slip op. at 26 (Traxler, J., dissenting). In ourview, however, the majority’s opinion is not quite so inflexible, and it certainly does not purport to reject a district court’s consideration of the totality of the circumstances in making its probable cause determination. Id. at17. We are satisfied that the totality of the circumstances present here supports the district court’s ruling.

**7** The fact that an officer may err on any given speed estimate and still obtain certification, as discussed above, is not dispositive to our inquiry here. The government’s probable cause burden requires no more than areasonable ground to believe that an offense has been committed, a standard far less exacting than that imposed on the government to prove guilt beyond a reasonable doubt. Indeed, we recently emphasized that "‘[f]inely-tuned standards such as proof beyond a reasonable doubt or by a preponderance of the evidence, useful in formal trials, have no place in a [probable cause] decision because probable cause is only the probability, and not a prima facie showing, of criminal activity.’" United States v.
Ortiz , 669 F.3d 439, 445 (4th Cir. 2012) (quoting Illinois v. Gates , 462 U.S. 213, 235 (1983)). 11

U NITED S TATES v. M UBDIspeed was credible. Reviewing the probable cause determination de novo, we agree with the district court that the traffic stop was supported by the officers’ reasonable belief that Mubdi was speeding.

2.

Mubdi also challenges the district court’s separate findingthat his following too closely behind Wolfe’s patrol car justified the traffic stop. Mubdi rightly notes that the North Carolina statute proscribing motorists from following too closely, N.C. Gen. Stat. § 20-152, is inapplicable when a motorist isovertaking another. He contends that, because he was overtaking a slower-moving truck in front of him in the right lane when he merged behind Wolfe, his conduct was permissible. As such, Mubdi argues that the officers made a mistake of lawby believing that he violated the statute. Tying up this argument, Mubdi asserts that the officers’ decision to stop him for following too closely was improper because "a mistake of lawcannot provide reasonable suspicion or probable cause to justify a traffic stop." Appellant’s Reply Br. 4 (quoting United
States v. Chanthasouxat , 342 F.3d 1271, 1279 (11th Cir. 2003) (concluding that "an officer’s reasonable mistake offact may provide the objective grounds for reasonable suspicion or probable cause required to justify a traffic stop, but an officer’s mistake of law may not")).

Mubdi’s argument here fails for two reasons. First, the evidence is at best conflicting as to whether Mubdi merged in theleft lane behind Wolfe’s patrol car to overtake a slowermoving vehicle, a necessary precondition for his conduct to be permissible under the statute. On this point, Mubdi simply averred that "there was a truck in front of [him] and to get around it, [he] merged behind the officer that was on the side." J.A. 269. On the other hand, York testified that "the Dodge Magnum ma[d]e a left behind [Wolfe] in a very close distance[, and] the truck [was] . . . at least ten car lengths in front of [Mubdi]." Id. 162. Additionally, Wolfe stated that he 12 U NITED S TATES v. M UBDI"wouldn’t say that [Mubdi] was getting ready to hit the truck or anything. They had plenty of time—they had more time totravel behind the vehicle before anything unsafe was to happen." Id. 250. In fact, the traffic stop video, submitted as anexhibit to the motion, appears to bear out the officers’ testimony.

Viewing the evidence in the light most favorable to the government, as we must when a motion to suppress has been denied, Kelly , 592 F.3d at 589, Mubdi falls far short of showing that his conduct was permissible under section 20-152 in the first place.

But even assuming that the officers were mistaken as to the
distance between Mubdi and the truck in front of him in the right lane, and thus whether Mubdi merged into the left lane to overtake the truck, such a mistake is patently a mistake of fact. Nothing in the record suggests that the officers wereunaware that section 20-152 exempts drivers from the prohibition on following too closely while they are overtaking a slower-moving vehicle.

Thus, to the extent that the officers honestly—although perhaps mistakenly—believed that Mubdi was violating section 20-152 by following Wolfe too closely while not overtaking a vehicle, this mistake is at most a reasonable one under the circumstances, which does not undermine the district court’s conclusion that the officers had probable cause to execute the stop in the first instance. See Chanthasouxat , 342 F.3d at 1276 ("[I]f an officer makes a traffic stop based on a mistake of fact, the only question is whether his mistake of fact was reasonable.").

Reviewing the probable cause determination de novo as it pertains to Mubdi’s following too closely, we agree with the district court that the traffic stop was justified on this basis as
well. 13

U NITED S TATES v. M UBDIB.

We next analyze whether the officers’ subsequent actions were " ‘reasonably related in scope to the circumstances that justified the [stop].’ " See United States v. Rusher , 966 F.2d 868, 875 (4th Cir. 1992) (quoting Terry v. Ohio , 392 U.S. 1, 20 (1968)). Traffic stops must be limited in both scope and
duration. See Florida v. Royer , 460 U.S. 491, 500 (1983) (plurality opinion). With respect to scope, "the investigative methods employed should be the least intrusive means reasonably available to verify or dispel the officer’s suspicion in a short period of time." Id. As for duration, the police must "diligently pursue[ ] a means of investigation that [is] likely to confirm or dispel their suspicions quickly." United States v. Sharpe , 470 U.S. 675, 686 (1985); see also Illinois v. Caballes , 543 U.S. 405, 407 (2005) (noting that a traffic stop maybecome "unlawful if it is prolonged beyond the time reasonably required to complete [its] mission"); Royer , 460 U.S. at500 (noting that the scope of a seizure "must be carefully tailored to its underlying justification," and that the government
bears the burden to "demonstrate that the seizure it seeks to justify . . . was sufficiently limited in scope and duration to satisfy the conditions of an investigative seizure").

In the context of traffic stops, police diligence encompasses requesting a driver’s license and vehicle registration, running a computer check, and issuing a ticket. United States v. Foreman , 369 F.3d 776, 781 (4th Cir. 2004); see also Branch , 537 F.3d at 337 ("If a police officer observes a traffic violation, he is justified in stopping the vehicle for long enough to issue
the driver a citation and determine that the driver is entitled to operate his vehicle."). If a police officer seeks to prolong a traffic stop to allow for investigation into a matter outsidethe scope of the initial stop, he must possess reasonable suspicion or receive the driver’s consent. Branch , 537 F.3d at 336. Additionally, "if the driver obstructs the police officer’s efforts in any way—for example, by providing inaccurate 14 U NITED S TATES v. M UBDIinformation—a longer traffic stop would not be unreasonable." Id.

Addressing Mubdi’s argument that the officers unlawfully prolonged the stop, the district court concluded as follows:

The duration of the seizure was reasonable for thepurpose of performing a routine traffic stop, particularly in light of the fact that it involved a determination of a rental contract which was submitted by the driver, Mr. Mubdi. The time of the detention for the purpose of the traffic stop was reasonable under the circumstances and the totality thereof. And it wasfurther testified [sic] by the growing reasonable suspicion of the officers. So even taken as a gross amount of time, it’s still reasonable.

J.A. 338-39.

On appeal, Mubdi asserts that the officers lacked reasonable suspicion to detain him after York issued the warning ticket, which resulted in the warrantless search of his car that uncovered the drugs and firearms. We disagree.

First, the district court correctly concluded that the officers’ actions were no more intrusive than necessary and that theydiligently pursued a means of investigation to confirm or dispel their suspicions. In Branch , we held that a traffic violation authorizes "a police officer to detain the offending vehicle foras long as it takes to perform the traditional incidents of a routine traffic stop," such as "request[ing] a driver’s license and vehicle registration, run[ning] a computer check, and issu[ing] a citation." 537 F.3d at 335 (quotation omitted). The record reveals that York did not stray from this holding, as he asked Mubdi only "ordinary inquiries incident to a routine traffic stop," id. at 338 (quotation omitted), and undertook his inves15 U NITED S TATES v. M UBDItigation expeditiously, completing the warning citation within
fifteen minutes. **8**

The district court also correctly determined that the following suspicious behavior supported York’s decision to extend the investigation: (1) Mubdi took an excessive amount of time to pull over; (2) he was exceedingly nervous; (3) he kept his foot on the car brake instead of shifting the transmission into park; (4) he could not provide details as to his destination or the family member he intended to visit; (5) he did not rent the car, contrary to what he told York; (6) he was not authorized to drive the rental car; and (7) the car was beyond the bounds authorized by the rental contract.

Although some of these facts, viewed in isolation, might beconsistent with innocent travel, the Supreme Court has recognized that such factors can, when taken together, give rise to reasonable suspicion. United States v. Sokolow , 490 U.S. 1, 9 (1989) ("Any one of these factors is not by itself proof of any illegal conduct and is quite consistent with innocent travel.But we think taken together they amount to reasonable suspicion."). Here, we have no trouble concluding that the circumstances supported York’s decision to extend the stop to conduct the open-air canine sniff, which in turn alerted the officers to the presence of contraband in the car.

We have emphasized that reasonable suspicion "is not readily, or even usefully, reduced to a neat set of legal rules, but, rather, entails common sense, nontechnical conceptions that deal with factual and practical considerations of everyday
life." United States v. Mason , 628 F.3d 123, 128 (4th Cir. 2010) (quoting Foreman , 369 F.3d at 781). As a reviewing court, we "consider the totality of the circumstances and give due weight to common sense judgments reached by officers

**8**Wolfe arrived at the scene of the stop with his drug-sniffing dog while York was issuing the warning citation, and thus the stop was not extended because of any delay in the arrival of a canine unit. 16 U NITED S TATES v. M UBDIin light of their experience and training." Id. (quotation omitted). On this record, we decline to disturb the district court’s order denying Mubdi’s motion to suppress.

III.

Lastly, Mubdi argues that the district court violated his Fifth and Sixth Amendment rights by increasing his statutory mandatory minimum sentence for the drug offenses based on improper judicial factfinding. Specifically, Mubdi contends that the district court’s finding that he was responsible for 290.5 grams of crack cocaine violated his Fifth and Sixth Amendment rights to have any fact that triggers an enhancedmandatory minimum sentence charged in the indictment, submitted to a jury, and proved beyond a reasonable doubt. Without this finding, Mubdi argues that his guilty plea to crimes involving at least fifty grams of crack cocaine would haveyielded only a ten-year mandatory minimum sentence. However, Mubdi acknowledges that Supreme Court precedent forecloses this argument. See Harris v. United States , 536U.S. 545, 568 (2002) (holding that increasing minimum sentence based on judicial factfinding "does not evade the requirements of the Fifth and Sixth Amendments").

Accordingly, we affirm the district court’s imposition of a 240-month sentence for Mubdi’s drug convictions, which, when combined with the sixty-month consecutive sentence applied on the § 924(c) charge, properly yielded a 300-month

term of incarceration.

IV.

For the foregoing reasons, we affirm the judgment of the

district court.

AFFIRMED 17 U NITED S TATES v. M UBDIDAVIS, Circuit Judge, concurring in part and in the judgment:

Judicial narratives that begin with a traffic stop are notable for their depressing sameness. Because of the nature of our judicial system, these narratives are typically inscribed in criminal prosecutions. Usually only those on whom contraband is found are charged with crimes, and those charged with crimes have the strongest incentive to challenge the stop that led to the discovery of contraband. Absent unusual events, courts tend to uphold such searches, finding them supported by probable cause.

There is no poetry in these narratives. They read like the documentation of an audit. The police go
about their business. Courts double-check them. Inmost cases, the court finds the law enforcement officers in compliance. In the process of all that process, we forget that–at least in criminal cases–someone’s
freedom is on the line.

Road ").

In Delaware v. Prouse , 440 U.S. 648 (1979), the Supreme Court, applying the doctrine of Terry v. Ohio , 392 U.S. 1(1968), definitively rejected, as inconsistent with the protections afforded by the Fourth Amendment, a claim to unfettered discretion to stop and detain motorists on the part of law enforcement officers seeking to uncover violations of the law:

[W]e hold that except in those situations in which there is at least articulable and reasonable suspicion
that a motorist is unlicensed or that an automobile isnot registered, or that either the vehicle or an occu18 U NITED S TATES v. M UBDIpant is otherwise subject to seizure for violation of law, stopping an automobile and detaining the driverin order to check his driver’s license and the registration of the automobile are unreasonable under the Fourth Amendment. This holding does not precludethe State of Delaware or other States from developing methods for spot checks that involve less intrusion or that do not involve the unconstrained
exercise of discretion.

Id. at 663. Justice Rehnquist, dissenting, discerned "[no] sufficient basis to distinguish for Fourth Amendment purposes between a roadblock stopping all cars and the random stop"
at issue in the case before the Court. Id. at 667. He scoffed at the majority’s determined effort to protect individual liberty, accusing the majority of "elevat[ing] the adage ‘misery lovescompany’ to a novel role in Fourth Amendment jurisprudence." Id. at 664.

Seventeen years later, a unanimous Supreme Court effectively vitiated the protections afforded by Prouse . In Whren
v. United States , 517 U.S. 806 (1996), the Court held that so long as an officer can offer a plausible account that he had probable cause a motorist committed a traffic infraction, whether the motorist could be stopped and detained was a matter entirely within the discretion of the officer. **1** Despitethe potential for selective and discriminatory "traffic enforcement," the officer’s "subjective intentions" in making the stop play no role in Fourth Amendment analysis. In particular, as the Court put it:

We of course agree with petitioners that the Constitution prohibits selective enforcement of the law
based on considerations such as race. But the constitutional basis for objecting to intentionally discrimi**1** This circuit anticipated Whren ’s holding in United States v. Hassan El

, 5 F.3d 726, 729–31 (4th Cir. 1993), cert. denied , 511 U.S. 1006 (1994). 19 U NITED S TATES v. M UBDInatory application of laws is the Equal Protection Clause, not the Fourth Amendment. Subjective intentions play no role in ordinary, probable-cause Fourth Amendment analysis.

Id. at 813. See generallyWayne R. LaFave, The "Routine Traffic Stop" from Start to Finish: Too Much "Routine," Not Enough Fourth Amendment, 102 Mich. L. Rev. 1843 (2004).

Over the ensuing sixteen years, judges, **2**legal scholars, social scientists, and many others have spilled much ink (and the country has witnessed considerable political discourse)exploring the ramifications of the Court’s about-face. Specifically, we have wrestled with the inevitable role that constitutionally-permissible "pretextual" traffic stops play in what the Court referred to as "ordinary, probable-cause Fourth Amendment analysis," Whren , 517 U.S. at 813, in light of the growth of racial profiling. **3**Professor Leong has crafted a cogent summary of the evolved legal regime:

**2** See, e.g.

, Atwater v. City of Lago Vista , 532 U.S. 318, 372 (2001) (O’Connor, J., dissenting) ("[A]s the recent debate over racial profiling demonstrates all too clearly, a relatively minor traffic infraction may often serve as an excuse for stopping and harassing an individual." (citing
Whren , 517 U.S. at 813)).

**3** At an earlier time, some law enforcement officers freely employed theterm "pretextual stop" although, with increased sensitivity over racial profiling, the term seems to have fallen from favor. See United States v. Foreman , 369 F.3d 776, 786-87 (4th Cir. 2004) (Gregory, J., concurring in part and dissenting in part):

Trooper Wade testified that he began to follow Foreman to "see if I could find a violation," id. at 30 (emphasis added), andadmitted "[i]n an attempt to find a violation on [Foreman’s] vehicle . . . I was going to conduct a pretextual stop, stop him for a traffic violation, conduct a brief interview of him, see if I observed any indicators of other criminal activity . . . . " Id. at 60(emphasis added). Because Trooper Wade paced Foreman’s vehicle at a speed of sixty-four miles per hour over a one-half mile stretch of road where the speed limit was fifty-five, and observed "items hanging from the inside rearview mirror," he activated hisemergency lights to make the stop, which Trooper Wade admitted was pretextual. See R. vol. 4 at 2. 20 U NITED S TATES v. M UBDIWhatever all this means in the abstract world of legal principles, the practical effect with respect to traffic stops is that when the police think a driver has committed any traffic violation, no matter how minor or how fleeting, they can pull him over. Thus, a driver might be pulled over for failing to signal for an appropriate length of time or for changing lanestoo close to an intersection–things most of us routinely do on our daily commutes. The police can also pull over a driver when they lack enough evidence to establish probable cause of a violation if, under Terry , they have reasonable suspicion that criminal activity is afoot.

These standards allow police officers to exercise an enormous amount of discretion in performingtraffic stops. Under current doctrine, the legal justification for stopping a car need not be the same as the real reason the police officer wants to stop the car,so long as a reasonable officer would have had probable cause to believe that a traffic infraction in fact took place. [Professor] Paul Butler [now of the Georgetown University Law Center] describes riding in a police cruiser with a police officer friend and playing a game his friend invented called "Stop that Car!" in which Butler "pick[s] a car–any car–and [the officer] stops it." Butler explains that his friend "is a good cop" because "[h]e waits until he has a legal reason to stop the car. It doesn’t take long, never more than three or four blocks of following. There are so many potential traffic infractions that it is impossible to drive without committing one." The reality, then, is that the police are free to pick a car they wish to stop, follow it until the driver inevitably violates one of the vehicle code’s myriad obscure provisions, and subsequently pull it over.

The Supreme Court has repeatedly interpreted the Constitution to permit this schism. Thus, even an 21

U NITED S TATES v. M UBDIofficer with no actual purpose other than to harass and annoy may–according to the Supreme Court–use a traffic stop as an entirely constitutional startingpoint for such actions, as long as an objectively reasonable evaluation would conclude that the officer had probable cause to believe that a traffic violation occurred at the time she made the stop.

From this starting point of an "objectively reasonable" stop supported by probable cause or reasonablesuspicion, the judicial narrative then follows a wellworn script. Courts typically examine whether the circumstances justified the traffic stop, and–evenmore typically–answer that question in the affirmative. This is so even when the events of the traffic stop stray beyond its ostensible justification. The Court has explained: "An officer’s inquiries into matters unrelated to the justification for the traffic stop . . . do not convert the encounter into something other than a lawful seizure, so long as those inquiries do not measurably extend the duration of the stop."

Fan, The Police Gamesmanship Dilemma in 22 U NITED S TATES v. M UBDIOf course, the four-decades-and-counting "War on Drugs" has given a special context and meaning to the Whrendoctrine and its implications for racial profiling. Beyond their undoubtedly sincere desire to do their jobs and to do them well and safely, local law enforcement officers and their employing agencies, such as the Statesville police departmentinvolved in this case, have serious skin in the drug interdiction game, no matter the ultimate destination of the contraband. See, e.g. , Ricardo J. Bascuas, Fourth Amendment Lessons from the Highway and the Subway: A Principled Approach to Suspicionless Searches, 38 Rutgers L.J. 719, 761-62 (2007) (discussing profits made by police from drug interdiction programs). It was not for nothing that officers York and Wolfe, each with a drug canine in his vehicle,started their shifts before nine in the morning sitting perpendicular to I-77 watching traffic, deciding which of the manyvehicles passing them by they would follow and stop, abjuring the use of the speed radar devices. **5**Likewise, it was not

**5** Insisting that the Statesville police were engaged in "criminal interdiction" and not merely "drug interdiction" at the time of the stop in this case,the officers’ supervisor, Captain Dyson, testified at the suppression hearing that York and Wolfe were "looking for criminals" who might be driving north on I-77 that morning. J.A. 126. The cross-examination of Dyson included the following:

or not? 23

M UBDIfor nothing that, as shown on the video taken by the dashboard camera in York’s vehicle, the officers in this case expressed unmitigated glee, punctuated by serial "fist-bumps" all around, when the cache of more than two hundred grams of crack cocaine was removed from the Dodge Magnum.

All that said, this court has done (and will continue to do)
what it can to hold true the line between excessive law enforcement zeal that transgresses constitutional limits, on theone hand, and legitimate law enforcement techniques respectful of constitutional constraints, on the other hand. See, e.g.

, United States v. Digiovanni , 650 F.3d 498 (4th Cir. 2011)(affirming district court’s grant of motion to suppress evidence seized after a traffic stop). At the constitutional margins, of course, one may yet legitimately question why, as Professor Leong correctly observed (and especially as the government bears the burden of proof), close calls seem always to go to law enforcement. See, e.g.

, United States v.

Mason , 628 F.3d 123, 132 (4th Cir. 2010) (holding that questioning of motorist and passenger unrelated to the basis for the traffic stop that took "one to two minutes" did not render stop unreasonable because the stop was conducted "promptly and with efficiency"); but see id. at 134-35 (Gregory, J., dissenting) (disagreeing that duration of stop was reasonable, where detaining officer described African-American occupants of stopped car as "spooky spooky" and officer’s testimony

A. There’s a bunch of things you look at. You look at criminalindicators when they’re coming by. How they position themselves when they come by. The expression they might give or the expression they don’t give. Or when they come by, somebody might just turn up a drink all of a sudden for no reason. Or whenthey come by – you’re sitting there watching traffic. All of a sudden when the car comes by, they all of a sudden take their hand and cover their face when they come by. It’s something that draws your attention to them. But you’re also looking for a motor
vehicle violation.

J.A. 128. 24 U NITED S TATES v. M UBDIsought to justify reasonable suspicion based on officer’s "experience" and "sort of gut instinct"). To be sure, given the relative institutional competencies between district and circuitcourts, and given the controlling standards of review of suppression rulings, see ante 7, trial judges, not the judges of this court, have the primary role in policing the police.

Our recent decision in United States v. Sowards , ___ F.3d ___, 2012 WL 2386605 (4th Cir. June 26, 2012), is whollyconsistent with our on-going efforts; it lays down an important marker that there are indeed limits to the scope of law enforcement creativity inherent in the otherwise standardless
Whrendoctrine. Unlike the majority here, however, I cannot identify any material differences in the facts at hand that willsupport a difference in outcome between this case and the outcome in Sowardson the issue of uncorroborated visual speed estimates, although I fully agree that Sowardsdoes not sound the death knell to the use of visual speed estimates by law
enforcement officers. **6**Accordingly, as to the justification for the vehicle stop in this case, I join only Part II.A.2 of the majority opinion, which, as an alternative holding, sustains
the district court’s determination that the ostensible following-too-closely violation supported the existence of probable cause to effect the vehicle stop here. I also concur in Parts I, II.B., and III of the majority opinion, and in the judgment.

**6** Interestingly, the evidence at the suppression hearing, including the officers’ testimony and images from the video taken by York’s dashboard camera, indicated that over the approximately five miles during which officers York and Wolfe surveilled Mubdi after they first observed the Dodge Magnum, the posted speed limits on I-77 and I-40 increased from fifty-five miles per hour (where the officers first observed Mubdi), to sixty miles per hour, to sixty-five miles per hour at the location where the traffic stop was finally effected. Apparently, the officers set up their "criminal interdiction" operation, in which visual estimates of vehicle speeds played a major role, at an optimal location to stop vehicles traveling more than the posted fifty-five mile per hour limit, and just before the limit increased to sixty, and then to sixty-five, miles per hour. 25
