BENTON, Circuit Judge.

       Geoffrey Scott Gaffney conditionally pled guilty to one count of possession
with intent to distribute 500 grams or more of methamphetamine, in violation of 21
U.S.C. §§ 841(a)(1) and 841 (b)(1)(A). He appeals the denial of his motion to
suppress evidence seized from his car. Having jurisdiction under 28 U.S.C. § 1291,
this court affirms.
                                          I.

       Officer Albert Bovy was stopped at a red light. Directly in front of him, he saw
Gaffney’s vehicle approaching the intersection from the opposite direction. As the
light changed to green, the vehicle, without slowing, moved through the intersection.
The officer made a u-turn to follow it. Gaffney immediately braked hard and made
a right turn. The officer turned on his lights. The vehicle stopped.

       Officer Bovy approached and said he estimated Gaffney was driving 50 to 55
mph in a 35 mph zone. Gaffney replied, “I thought I was only going in the 40s.”
While he was looking for an insurance card, dispatch told the officer that Gaffney had
a previous narcotics history and was still involved in illegal narcotics. Returning to
the vehicle, the officer noticed Gaffney appeared nervous with beads of sweat on his
forehead, a shaky voice and hands, and heavy breathing. The officer asked if he had
any drugs or weapons in the vehicle. Gaffney answered “no” but declined permission
to search his vehicle. The officer ordered him to exit the vehicle to prepare for a dog
sniff (the officer had the dog in his car). Conducting a pat-down search, the officer
detected a long round object with a bulb on the end. He asked Gaffney about it.
Gaffney said nothing was in his pocket. The object was a meth pipe. The officer
arrested Gaffney and had the vehicle towed. An inventory search uncovered two
large Ziploc bags with four pounds of ice meth.

       Gaffney moved to suppress any evidence from the traffic stop, challenging both
the lawfulness of the stop and the pat-down search. At the suppression hearing,
Officer Bovy testified he received training in identifying speed eleven years earlier.
He typically did not “do much in the way of speed violations,” and did not remember
if he had “ever” turned on his in-car radar unit. He said his estimate of 50-55 mph
was based on his general experience with traffic stops and his familiarity with the
area. He did not know the distance the car traveled from when it first appeared until

                                         -2-
it passed him. Gaffney presented evidence that his vehicle traveled about 473 feet in
nine seconds, an average speed of 35.8 miles per hour.1

       The district court2 denied the motion. Gaffney entered a conditional guilty
plea, preserving the right to appeal both issues.

       “In an appeal from a district court’s denial of a motion to suppress evidence,
this court reviews factual findings for clear error, and questions of constitutional
law de novo.” United States v. Gordon,

      Gaffney argues Officer Bovy had neither reasonable suspicion nor probable
cause for a traffic stop. “[T]o justify [a traffic stop], officers need only ‘reasonable
suspicion.’” Heien v. North Carolina, 

, 536 (2014). Reasonable
suspicion exists when an officer has a “particularized and objective basis for
suspecting the particular person stopped of breaking the law.”

       The video from the officer’s dash-camera shows Gaffney’s headlights coming
into view directly in front of him and passing him nine seconds later. A defense
investigator estimated the location of Gaffney’s vehicle when it first appeared. The
distance between this location and Bovy’s location is 473 feet.

California, 

, 2482 (2014). “The determination of whether . . .
reasonable suspicion existed is not to be made with the vision of hindsight, but
instead by looking to what the officer reasonably knew at the time.” United States
v. Hollins, 

, 706 (8th Cir. 2012) (internal quotation marks omitted).
“Even an officer’s incomplete initial observations may give reasonable suspicion for
a traffic stop.” United States v. Givens, 

, 989 (8th Cir. 2014) (internal
quotation marks omitted). “Mistakes of law or fact, if objectively reasonable, may
still justify a valid stop.” 

.

       This court has not resolved whether an officer’s visual estimate of speed alone
can furnish either probable cause or reasonable suspicion to stop a vehicle. This court
has held that a “helicopter unit’s independent, continued observation of [a] speeding
[vehicle] is enough alone to justify [a] stop of the vehicle.” 

.
The Tenth Circuit has observed, “It’s long been the case that an officer’s visual
estimation can supply probable cause to support a traffic stop for speeding in
appropriate circumstances.” United States v. Ludwig, 

, 1247 (10th Cir.
2011). In that case, the district court found credible the trooper’s visual estimate,
noting his good view to gauge the approaching vehicle, the clear day, the trooper’s
15 years’ experience as a highway patrolman watching cars and estimating speeds,
and the lack of reasons to discredit the speed estimate. “In these circumstances, the
district court’s factual finding about the reliability of the trooper’s visual estimation
remains untouched, must be affirmed, itself sufficient to support the traffic stop.” 

      The Fourth Circuit addressed an officer’s visual estimate that a defendant was
over the posted speed limit by only five miles per hour.

      [T]he 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


                                          -4-
      probable cause to initiate a traffic stop. Instead, for the purposes of the
      Fourth Amendment, the question remains one of reasonableness.
      Critically, and as further explained below, the reasonableness of an
      officer’s visual speed estimate depends, in the first instance, on whether
      a vehicle’s speed is estimated to be in significant excess or slight excess
      of the legal speed limit. If slight, then additional indicia of reliability
      are necessary to support the reasonableness of the officer’s visual
      estimate.

United States v. Sowards, 

, 591 (4th Cir. 2012). That court found “at
a minimum, there must be sufficient indicia of reliability for a court to credit as
reasonable an officer’s visual estimate of speed.” 

case, the Fourth
Circuit emphasized that “the probable cause inquiry is—as always—reasonableness,
and the analysis remains whether the ‘totality of circumstances’ established the
‘reasonableness of the officer’s visual speed estimate.’” United States v. Mubdi, 

, 339 (4th Cir. 2012) (finding that the totality of circumstances supports the
stop when two officers each independently determined, by visual observation, that the
defendant was exceeding the speed by 8 to 10 mph) (quoting 

), vacated on other grounds in, 

(2013).

       In this case, the district court found that Officer Bovy “only rarely issues
speeding citations,” was “unsure whether he has actually ever turned on his in-car
radar,” “his experience with traffic stops is unrelated to speeding violations,” and he
“was unable to even provide an estimated distance that Defendant’s vehicle traveled.”
United States v. Gaffney, 

, at *4 (N. D. Iowa, February 27, 2014).
Unlike Ludwig, the district court specifically said it did “not place a great deal of
confidence in Officer Bovy’s estimation of the speed of the vehicle.” 

on dash-camera video and the measurement by the defense investigator, the
district court found “the totality of the circumstances establishes the reasonableness
of Officer Bovy’s belief that Defendant was speeding as he approached the
intersection.” 

The court noted: “Because this was an average speed,


                                         -5-
Defendant likely traveled faster than 35.8 miles per hour at some point or points over
the course of the nine seconds.” 

district court lacked confidence in the officer’s estimate, the issue
is not whether the evidence supports his belief that Gaffney was traveling at 50-55
mph. “[S]earches and seizures based on mistakes of fact can be reasonable.” 

. The issue is whether the totality of the circumstances at the time
of the stop supports the reasonableness of the officer’s belief that Gaffney was
speeding at all. See United States v. $45,000 in U.S. Currency, 

, 715
(8th Cir. 2014) (“Any traffic violation, however minor, provides probable cause for
a traffic stop.”).

       Officer Bovy was familiar with the area, thought Gaffney was speeding, and
Gaffney “braked hard” immediately after Bovy u-turned to follow him. Based on the
totality of these facts—corroborated by Gaffney’s admission and the investigator’s
measurement—the district court correctly concluded that Officer Bovy’s belief that
Gaffney was speeding was objectively reasonable.

                                           B.

      Gaffney challenges the pat-down search arguing that Officer Bovy had no
reason to suspect he was armed and dangerous. “Officers may conduct a protective
pat-down search for weapons during a valid stop . . . when they have objectively
reasonable suspicion that a person with whom they are dealing might be armed and
presently dangerous and criminal activity might be afoot.” United States v. Preston,

, 689 (8th Cir. 2012) (internal quotation marks omitted). “In
determining whether reasonable suspicion exists, we consider the totality of the
circumstances in light of the officers’ experience and specialized training.” 

is permissible if a reasonably prudent man in the circumstances would be


                                           -6-
warranted in the belief that his safety or that of others was in danger.” 

marks omitted).

       The stop occurred late at night in a high-crime area. United States v.
Roggeman, 

, 578 (8th Cir. 2002) (“Trooper Moore was alone, he
stopped Roggeman late at night, and the scene of the stop was poorly lit. These facts
go to officer safety.”). Gaffney was abnormally nervous. See United States v.
Hanlon, 

, 930 (8th Cir. 2005) (“Hanlon’s extreme nervousness and
failure to make eye contact with Halverson bolstered Halverson’s reasonable
suspicion that Hanlon was armed and dangerous.”). Officer Bovy was told that he
had a narcotics conviction and was still involved in the narcotics trade. “[I]t is
reasonable for an officer to believe a person may be armed and dangerous when the
person is suspected of being involved in a drug transaction.” United States v.
Bustos-Torres, 

, 943 (8th Cir. 2005). Officer Bovy had reasonable
suspicion that Gaffney could be armed and dangerous and criminal activity was afoot.
The district court did not err in upholding the pat-down search.

      The judgment is affirmed.

                                    *******

BYE, Circuit Judge, dissenting.

       I disagree an objectively reasonable officer would have had a sufficient basis
to stop Gaffney’s car for speeding. Consequently, I would reverse the district court’s
denial of Gaffney’s motion to suppress, vacate his conviction, and remand for further
proceedings. I therefore respectfully dissent from Section II.A. of the majority’s
opinion and would not reach Section II.B.




                                         -7-
        “[T]he underlying command of the Fourth Amendment is always that searches
and seizures must be reasonable . . . .” Wilson v. Arkansas, 

, 931 (1995)
(internal quotation marks omitted). As applicable to Gaffney’s case, a traffic stop is
reasonable “when an officer is aware of particularized, objective facts which, taken
together with rational inferences from those facts, reasonably warrant suspicion” that
a traffic violation has occurred. United States v. Gordon, 

, 876 (8th Cir.
2013) (internal quotation marks omitted).

       The objective facts of Gaffney’s case are contained within the video created by
the dashboard camera located in Officer Bovy’s patrol car. From this video, the
investigator determined Gaffney’s vehicle traveled at an average of 35.8 miles per
hour, in a 35 mile per hour speed zone, from the time Officer Bovy could first see
Gaffney’s vehicle on Franklin Street until the point where Gaffney’s vehicle was
parallel with Officer Bovy’s patrol car. Over the course of this period, the vehicle
appears to travel at a consistent speed, and Gaffney does not brake until after his
vehicle has already passed Officer Bovy’s patrol car. Further, when Gaffney brakes,
he is doing so to slow his vehicle to make a right turn and almost immediately stops.
All of these events occurred during nighttime hours.

       From these facts, the majority somehow concludes a reasonable officer would
have a sufficient basis to stop Gaffney for speeding. I disagree. To conclude Officer
Bovy or any other officer could visually discern a difference of a mere .8 miles per
hour above the posted speed limit is confounding. See United States v. Sowards, 

, 594 (2d Cir. 2012) (“[T]he accuracy of human estimation of speed cannot
easily, readily, and accurately determine between such small variations [5 m.p.h.] in
speed.” (internal quotation marks omitted)). Moreover, although this figure is an
average, and the district court concluded Gaffney “likely traveled faster than 35.8
miles per hour at some point or points over the course of the nine seconds,” the
objective facts do not support this conclusion. The video shows Gaffney’s vehicle



                                         -8-
traveling at a consistent speed, and he did not begin to slow his vehicle until he
passed the end point of the investigator’s measurements.

       Further, the majority attempts to make Officer Bovy’s familiarity with the area
and that he thought Gaffney was speeding into objective facts. While courts have
considered an officer’s visual estimation of speed as an objective fact to consider in
the reasonable suspicion analysis, those courts have found the officers had the
necessary skills, training, and experience to make such an estimation. See United
States v. Mubdi, 

, 341 (4th Cir. 2012), vacated on other grounds, 133 S.
Ct. 2851 (2013) (finding officers’ visual estimates were sufficient to support probable
cause because the two officers gave virtually identical estimates and were required,
as part of a radar certification class, to visually estimate the speed of vehicles within
a narrow margin of error); United States v. Ludwig, 

, 1247 (10th Cir.
2011) (crediting an officer’s visual estimation of speed to determine whether probable
cause to stop existed partially because the officer possessed 15 years’ experience as
a highway patrolman watching cars and estimating speeds); State v. Dunham, 

, 279 (Vt. 2013) (considering whether officers “receive[d] proper roadside and
academy training, [have] spen[t] considerable time on road patrol, gain[ed]
experience estimating speed and comparing estimates against radar, and historically
exhibit[ed] a margin of error of only a few miles per hour” as factors to determine
whether the officers are qualified to visually estimate speed).

       Contrary to cases which have utilized officers’ estimations as objective facts,
Officer Bovy lacked the credentials to visually estimate speed. He received visual
estimation speed training over a decade prior to Gaffney’s stop, he did not provide
a margin of error as to how accurate any visual estimations of speed he previously
made had been, he had issued very few speeding citations, and he believed he had
never turned on the radar in his patrol car. Further, he was unable to provide an
estimate of the distance Gaffney’s car covered as it approached Officer Bovy’s patrol
car although he explained monitoring the distance a vehicle travels over a surface

                                          -9-
area is part of the technique he utilizes for visually estimating speed. Because of
Officer Bovy’s inexperience in visually estimating speed, he grossly estimated that
Gaffney’s speed was 50 to 55 miles per hour, well above Gaffney’s actual average
speed. Officer Bovy’s estimation is therefore subjective and does not have the
support to be considered as a particularized, objective fact when determining whether
reasonable suspicion existed. See 

, 594 (finding that
because an officer lacked specialized training in the estimation of vehicle speeds,
lacked a technique or method to “guess” visual speeds, and had difficulty with
measurements, his visual estimation of speed “was in fact a guess that was merely
conclusory, without an appropriate factual foundation, and simply lacking in the
necessary indicia of reliability to be an objectively reasonable basis for probable
cause to initiate a traffic stop”).

       The only other objective facts cited by the majority to support its conclusion
are that Gaffney admitted to driving “in the 40s” and he “braked hard” after Officer
Bovy made a u-turn. First, I do not believe we can consider Gaffney’s alleged
admission to speeding because Officer Bovy testified Gaffney made this statement
after Officer Bovy had already stopped the vehicle. See United States v. $45,000.00
in U.S. Currency, 

, 715 (8th Cir. 2014) (“[I]f it was not objectively
reasonable for the officer to believe that a violation was occurring at the time that the
officer decided to effect the stop, then the officer lacked probable cause to seize the
motorist. . . . Accordingly, the critical inquiry . . . is what the stopping officer
observed before pulling over a motorist.”); see also United States v. Sanders, 

, 913 (8th Cir. 1999) (“The determination of whether probable cause existed
is not to be made with the vision of hindsight, but instead by looking to what the
officer reasonably knew at the time.”).

       Second, the video taken by the dashboard camera does not support Officer
Bovy’s assertion that Gaffney “braked hard” after he passed Officer Bovy’s patrol
car. Instead, the video depicts Gaffney braking at a reasonable pace to make a right

                                          -10-
turn and immediately stop. Nonetheless, even if we were to consider braking as an
objective fact, courts have not found braking, standing alone, as a sufficient basis to
conclude an individual was speeding; rather, other indicia of speeding were present
which supported the constitutionality of the traffic stop. See United States v. Colden,
No. 11-M-989-SKG, 

, at *1 (D. Md. Oct. 21, 2011) (finding the
officer’s uncontested visual estimation of defendant’s speed, combined with the
officer’s observations that the vehicle shook and defendant tapped his brakes,
amounted to reasonable articulable suspicion that defendant was speeding); State v.
Steele, No. 101,250, 

, at *3 (Kan. Ct. App. Oct. 23, 2009) (finding
substantial competent evidence supporting the trial court’s finding of reasonable
suspicion of speeding because the officer observed defendant traveling at an
excessive rate of speed, the officer heard a loud engine roar, and the officer observed
defendant slam on his brakes). Gaffney’s case lacks any other objectively reasonable
indication that he was speeding, and as a result, braking alone cannot provide
reasonable suspicion for stopping his vehicle.

      For the reasons provided, I would reverse the denial of Gaffney’s motion to
suppress, vacate his conviction, and remand for further proceedings.
