    SILBERMAN.
    EDWARDS, Senior Circuit Judge: On March 25, 2014,
    Appellant Harold Castle was charged, in a one-count
    indictment, with possession with intent to distribute 100
    grams or more of a mixture containing a detectable amount of
    phencyclidine (“PCP”), in violation of 
    21 U.S.C. §§ 841
    (a)(1)
    and (b)(1)(B)(iv). The charge was based on physical evidence
    and a statement obtained as a result of Appellant’s warrantless
    seizure on the evening of February 24, 2014. Prior to trial,
    Appellant filed a motion to suppress the evidence, arguing
    that he was stopped by police officers without reasonable,
    articulable suspicion in violation of the Fourth Amendment.
    After a hearing, the District Court denied the motion. A jury
    found Appellant guilty of the lesser-included offense of
    possession with intent to distribute a detectable amount of
    PCP, in violation of 
    21 U.S.C. §§ 841
    (a)(1) and (b)(1)(c). On
    October 21, 2014, the District Court sentenced Appellant to
    65 months imprisonment to be followed by six years of
    supervised release. Appellant now appeals the denial of his
    suppression motion.
    I. INTRODUCTION
    The District Court found that, on the evening in question,
    the seizing officers were on patrol in an unmarked pickup
    truck. The officers turned onto Yuma Street (a residential
    block in southeast Washington, D.C.) and saw Appellant
    walking quickly from the direction of an apartment complex
    outside of which PCP was known to be sold and toward an
    alleyway next to a house across the street. The alley led to a
    3
    vacant yard. The District Court also found that, after they
    pulled up in front of the house, the officers saw Appellant
    lean over near a U-Haul truck parked in the yard.
    The District Court additionally credited the officers’
    testimony that they patrolled the area so regularly that “people
    in the neighborhood” had come to recognize their unmarked
    truck as a police vehicle, to expect such patrols, and to act as
    “lookouts.” On the basis of these generalized findings
    regarding “the neighborhood,” the District Court concluded
    that it was “not unreasonable for the officers to believe
    [Appellant] knew or suspected their vehicle was a police
    vehicle.” Consequently, the District Court found that it also
    was not unreasonable for the officers to believe that Appellant
    was walking quickly in order to evade them and that he
    leaned over near the U-Haul in response to their presence.
    Finally, the District Court found that when the officers
    approached Appellant as he walked out of the backyard area,
    they recognized him from several prior seizures that had
    occurred some six to nine months earlier. Based on the
    totality of the foregoing findings of historical fact and
    inferences from those facts, the District Court concluded that
    the officers had reasonable, articulable suspicion that
    Appellant had just committed or was about to commit a
    criminal offense when they seized him. We disagree.
    “Under the Fourth Amendment our society does not
    allow police officers to ‘round up the usual suspects.’” United
    States v. Laughrin, 
    438 F.3d 1245
    , 1247 (10th Cir. 2006). An
    officer relying on his or her “knowledge of [an individual’s]
    criminal record” is “required to pair” that knowledge with
    “‘concrete factors’ to demonstrate that there [is] a reasonable
    suspicion of current criminal activity.” United States v.
    Foster, 
    634 F.3d 243
    , 247 (4th Cir. 2011) (emphasis added)
    (citation omitted). In other words, knowledge of an
    4
    “individual’s criminal history” can “corroborate[],” but not
    substitute for “objective indications of ongoing criminality.”
    United States v. Monteiro, 
    447 F.3d 39
    , 47 (1st Cir. 2006).
    The law also makes clear what is eminently logical. In
    order to find that a person is evading the police, there must be
    evidence that the person has knowledge of a police presence.
    See Illinois v. Wardlow, 
    528 U.S. 119
    , 124 (2000). Similarly,
    in the context of a reasonable, articulable suspicion analysis,
    “furtive gestures ‘are significant only if they were undertaken
    in response to police presence.’” United States v. Brown, 
    334 F.3d 1161
    , 1168 (D.C. Cir. 2003) (quoting United States v.
    Edmonds, 
    240 F.3d 55
    , 61 (D.C. Cir. 2001) (quoting United
    States v. Johnson, 
    212 F.3d 1313
    , 1316 (D.C. Cir. 2000))). In
    both instances, the putatively evasive or furtive conduct
    cannot provide the necessary evidence of knowledge of a
    police presence. There must be independent evidence from
    which that knowledge can be inferred. See Wardlow, 
    528 U.S. at 124
    ; Brown, 
    334 F.3d at 1168
    ; Edmonds, 
    240 F.3d at 57, 61-62
    ; Johnson, 
    212 F.3d at 1316-17
    .
    As we explain more fully below, there is no such
    evidence here. Certainly the officers’ assumption that
    Appellant knew of the presence of their truck on the evening
    in question gains no support from general knowledge in the
    neighborhood that the truck was a police vehicle. The ability
    of neighborhood people to recognize the truck as a police
    vehicle cannot support an inference that Appellant had
    knowledge of the presence of that known police vehicle on
    the evening he was stopped. And the record is entirely devoid
    of any evidence from which a reasonable officer could infer
    that Appellant knew of the truck’s (and therefore the
    officers’) presence before he was stopped. There is, for
    example, no testimony that Appellant so much as glanced in
    the direction of the officers’ truck at any point after the
    5
    officers turned onto Yuma Street. Nor is there evidence that
    Appellant was ever in close proximity to the truck. Neither
    did the officers testify that anyone else in the neighborhood
    alerted Appellant or that a “lookout” set off a general alarm
    that a known police vehicle was on the block. In other words,
    the officers’ critical assumption of knowledge was based on
    nothing.
    It is therefore clear that the Government failed to carry its
    burden of demonstrating that the actions of Appellant on the
    evening in question amounted to “concrete factors” or
    “objective indications” that he had just committed or was
    about to commit a criminal offense. Walking quickly on a
    very cold evening is commonplace, not suspicious, activity.
    So, too, is walking into an alleyway, leaning over, and
    walking out. These actions are entirely mundane. The fact that
    they took place in a residential neighborhood plagued by drug
    use did not allow the police officers to ignore the dictates of
    the Fourth Amendment. See United States v. Sprinkle, 
    106 F.3d 613
    , 618 (4th Cir. 1997) (prior conviction “for a
    narcotics offense” and presence “in a neighborhood with a
    high incidence of drug traffic,” without “(other) particularized
    evidence that indicates criminal activity is afoot,” is
    insufficient to demonstrate reasonable, articulable suspicion).
    Under Ornelas v. United States, 
    517 U.S. 690
     (1996), we
    give “due weight” to a District Court’s determination of the
    reasonableness of inferences drawn by police officers from
    historical facts. 
    Id. at 700
    . In assessing this determination,
    however, we are obliged to adhere to the Supreme Court’s
    admonition that “due weight must be given, not to [an
    officer’s] inchoate and unparticularized suspicion or ‘hunch,’
    but to the specific reasonable inferences which he is entitled
    to draw from the facts in light of his experience.” Terry v.
    Ohio, 392 U.S 1, 27 (1968). As we explain below, because the
    6
    District Court’s determination that the officers’ inference that
    Appellant was aware of their presence had no basis in the
    factual record, it is entitled to no weight. We therefore
    reverse.
    II. BACKGROUND
    The events giving rise to Appellant’s seizure took place
    on February 24, 2014, in the 100 block of Yuma Street,
    Southeast, Washington, D.C. This long block, which begins at
    First Street on the west and terminates in a cul-de-sac on the
    east, consists of a mix of small apartment buildings and single
    family homes.
    At approximately 6:30 p.m. on a very cold evening,
    Metropolitan Police Department Officers Olszak and Moseley
    were patrolling in an undercover police vehicle – an
    unmarked Dodge Ram truck. The officers were not in
    uniform, but were wearing vests with the word “Police” on
    the front and back. Upon turning onto the 100 block of Yuma,
    the officers noticed two men at the opposite end of the block,
    near the cul-de-sac. What caught the officers’ attention was
    the fact that the men were walking quickly as they crossed
    from the right sidewalk near 133 Yuma – an apartment
    building in front of which PCP was known to be sold – to 144
    Yuma, a single family home on the opposite side of the street.
    As the officers drove toward the cul-de-sac, Appellant
    continued across the street and into an alleyway between 144
    Yuma and the house next door, out of the officers’ field of
    vision. The officers sped up a bit; however, when they pulled
    up in front of 144 Yuma, Appellant had nearly reached a U-
    Haul truck parked in the backyard of 144 Yuma, some 125
    feet from the street. The other man, later identified as a Mr.
    Banks, had stopped at the front corner of 144 Yuma,
    7
    apparently to urinate. The officers got out of their truck, and
    Officer Olszak ran toward the alleyway after Appellant, while
    Officer Moseley walked over to Mr. Banks.
    Just before Officer Olszak entered the alley, he saw
    Appellant, now on the far side of the U-Haul, bend over while
    one of his legs “kick[ed] up” parallel to the ground and then
    stand back up. Officer Moseley, still near the front of the
    house, saw Appellant bend over, but did not see his leg lift up.
    Each officer’s view was partially obstructed by the U-Haul.
    At this point, neither officer had recognized Appellant as
    Harold Castle.
    The officers then observed Appellant walking back
    toward Yuma Street with his hands in his pockets. Officer
    Olszak, who came face to face with Appellant in the alleyway
    between the houses, ordered Appellant to remove his hands
    from his pockets. It was only after Appellant obeyed Officer
    Olszak’s order that Officer Olszak recognized him as Harold
    Castle.
    Officer Olszak had, on several prior occasions, seen
    Appellant in front of the apartment building at 133 Yuma
    Street with other men. Officer Olszak also recognized
    Appellant from several prior seizures that occurred some six
    to nine months earlier. Two of these prior seizures resulted in
    Appellant’s arrest for PCP-related crimes. One involved a car
    and foot chase in a different neighborhood. Another, which
    took place in front of 133 Yuma Street, involved an attempt
    by Appellant to avoid arrest by disposing of a vial of liquid
    that had the distinct odor of PCP. And one seizure involved a
    foot chase that started in the 100 block of Yuma, but turned
    up no contraband and so Appellant was not arrested.
    8
    Having recognized Appellant as Mr. Castle, Officer
    Olszak touched him on his arm and told him to “hold on for a
    sec.” Officer Olszak then ran to the backyard to investigate
    the U-Haul truck. Meanwhile, Appellant walked over to
    Officer Moseley, who had detained Mr. Banks following a
    consensual frisk that had turned up no contraband.
    As Appellant neared Officer Moseley, Moseley
    recognized him as Harold Castle. Like Officer Olszak, Officer
    Moseley was familiar with Appellant as a result of Appellant
    having been seized in the past and his general presence in the
    neighborhood. Officer Moseley also smelled the odor of PCP
    emanating from Appellant.
    At this point, Appellant had put his hands back in his
    pockets and appeared agitated and nervous. Officer Moseley
    ordered him to sit down on the curb. Appellant sat down, but
    immediately jumped back up, complaining that his pants were
    clean and he did not want to get them dirty. Officer Moseley
    again told Appellant to sit down, and he complied.
    While Appellant was sitting on the curb, Officer Moseley
    saw him place a small vial on the ground and lean over it.
    Based upon the vial’s appearance and its smell, Officer
    Moseley suspected that it contained PCP. Officer Moseley
    arrested Appellant shortly afterward. In a search incident to
    that arrest, officers recovered a pack of cigarettes, a cell
    phone, a pair of black rubber gloves, paperwork in
    Appellant’s name, and approximately fifteen dollars in cash.
    While Officer Moseley was interacting with Appellant on
    Yuma Street, a crime scene search officer joined Officer
    Olszak at the U-Haul. Sometime after Appellant was arrested,
    Officer Olszak and the crime scene search officer found an
    9
    eight-ounce bottle of liquid near the U-Haul that smelled like
    PCP, as well as a plastic bag of black vial caps.
    After being charged and prior to trial, Appellant filed a
    motion to suppress the evidence obtained as a result of his
    seizure, including the one-ounce vial recovered by Officer
    Moseley and a statement Appellant allegedly made when
    arrested. Appellant did not seek to suppress the eight-ounce
    bottle of PCP or the vial caps. During a hearing before the
    District Court, Officers Olszak and Moseley provided the
    only evidence regarding the events leading to Appellant’s
    arrest.
    Based on the officers’ testimony, the District Court made
    findings of fact and determined that, as a matter of law,
    Officer Olszak stopped Appellant when he touched him on
    the arm and instructed him to “hold on.” The Court also
    determined that at that point, the officers had reasonable,
    articulable suspicion to stop Appellant. The District Court
    consequently denied Appellant’s motion to suppress.
    III. STANDARDS OF REVIEW
    When presented with an appeal of the denial of a motion
    to suppress evidence on Fourth Amendment grounds, we
    review de novo preserved claims regarding whether and when
    a seizure occurred. See United States v. Brodie, 
    742 F.3d 1058
    , 1061 (D.C. Cir. 2014). We also review de novo a
    district court’s “ultimate determination[]” of whether a police
    officer had the reasonable, articulable suspicion or probable
    cause necessary to legally effectuate any such seizure.
    Ornelas v. United States, 
    517 U.S. 690
    , 697, 699 (1996); see
    also United States v. Bailey, 
    622 F.3d 1
    , 5 (D.C. Cir. 2010).
    Under Ornelas, we give “due weight” to a District Court’s
    determination of the reasonableness of inferences drawn by
    10
    police officers from historical facts. 
    517 U.S. at 700
    . In
    assessing this determination, however, we are obliged to
    adhere to the Supreme Court’s admonition that “due weight
    must be given, not to [an officer’s] inchoate and
    unparticularized suspicion or ‘hunch,’ but to the specific
    reasonable inferences which he is entitled to draw from the
    facts in light of his experience.” Terry, 392 U.S at 27. While
    we “may consider both evidence offered at the suppression
    hearing and the trial,” Bailey, 
    622 F.3d at 5
    , when, as here, the
    District Court has made factual findings, we may not search
    the record for any reasonable view of the evidence that will
    support the trial judge’s conclusions, 
    id.
     at 5 n.1. Rather, we
    must review the factual findings of the District Court and,
    assuming they are not clearly erroneous, determine whether
    they support the contested seizure. See 
    id.
     Finally,
    suppression arguments that are not presented to the trial court
    are deemed waived and cannot be argued on appeal. See
    United States v. Hewlett, 
    395 F.3d 458
    , 460-61 (D.C. Cir.
    2005).
    IV. ANALYSIS
    A. The Seizure
    “[W]henever a police officer accosts an individual and
    restrains his freedom to walk away, he has ‘seized’ that
    person, and the Fourth Amendment requires that the seizure
    be ‘reasonable.‘” Brown v. Texas, 
    443 U.S. 47
    , 50 (1979)
    (alteration in original) (citations omitted). A seizure occurs
    “when physical force is used to restrain movement or when a
    person submits to an officer’s ‘show of authority.’” Brodie,
    742 F.3d at 1061 (quoting California v. Hodari D., 
    499 U.S. 621
    , 626 (1991)).
    11
    Whether police action amounts to a “show of authority”
    requires the court to ask whether a “reasonable person” “in
    view of all the circumstances surrounding the incident, . . .
    would have believed that he was not free to leave.” United
    States v. Wood, 
    981 F.2d 536
    , 539 (D.C. Cir. 1992) (quoting
    United States v. Mendenhall, 
    446 U.S. 544
    , 554 (1980)).
    Factors considered in assessing whether an officer’s actions
    amounted to a show of authority “include whether the suspect
    was physically intimidated or touched, whether the officer
    displayed a weapon, wore a uniform, or restricted the
    defendant’s movements, the time and place of the encounter,
    and whether the officer’s ‘use of language or tone of voice
    indicat[ed] that compliance with the officer’s request might be
    compelled.’” 
    Id.
     (alteration in original) (quoting Mendenhall,
    
    446 U.S. at 554
    ).
    The Supreme Court has repeatedly held that police do not
    manifest a show of authority “merely [by] approaching an
    individual on the street or in another public place, by asking
    him if he is willing to answer some questions, [or] by putting
    some questions to him if the person is willing to listen,”
    provided the officers do not imply that answers are obligatory.
    Florida v. Royer, 
    460 U.S. 491
    , 497 (1983) (plurality
    opinion); see also Florida v. Bostick, 
    501 U.S. 429
    , 434
    (1991); Florida v. Rodriguez, 
    469 U.S. 1
    , 5-6 (1984) (per
    curiam); INS v. Delgado, 
    466 U.S. 210
    , 215-17 (1984);
    Mendenhall, 
    446 U.S. at 555
    ; United States v. Lewis, 
    921 F.2d 1294
    , 1297-98 (D.C. Cir. 1990) (no seizure arises when
    officers, “displaying no weapons and speaking in a normal
    tone of voice, approach individuals in a public place and ask
    permission to talk with them” (citation omitted)).
    If police behavior amounts to a show of authority, a
    seizure will be found if the individual at whom the show of
    12
    authority is directed submits. Hodari D., 
    499 U.S. at 628-29
    ;
    see also Brodie, 742 F.3d at 1061; Wood, 981 F.2d at 538.
    Relying on Hodari D. and Brodie, Appellant, who bears
    the burden of demonstrating that he was seized, see United
    States v. Goddard, 
    491 F.3d 457
    , 462 (D.C. Cir. 2007) (per
    curiam), argues that he was stopped when Officer Olszak
    ordered him to remove his hands from his pockets and he
    complied. A careful review of the record, however, leaves no
    doubt that Appellant did not preserve this claim. Quite the
    contrary. The record is clear that Appellant’s counsel’s
    argument was that the stop was inexorably tied to Officer
    Olszak’s touch and directive to “hold on.” Tr. of Motions
    Hearing at 120-21, 130 (June 30, 2014). Consequently,
    Appellant’s claim regarding the stop is similarly limited
    before this court. See Hewlett, 
    395 F.3d at 460-61
    .
    We agree with the District Court that Appellant was
    seized when Officer Olszak touched Appellant and instructed
    him to “hold on” and Appellant complied. Applying the
    Mendenhall factors, we are satisfied that Appellant was
    subject to the requisite show of authority when Officer
    Olszak, wearing a vest labeled “Police,” ran up to him in a
    dark, narrow alley (effectively blocking Appellant’s path to
    Yuma Street), “ordered” Appellant to remove his hands from
    his pockets, and, in response to Appellant’s unquestioning
    compliance, initiated physical contact and instructed
    Appellant to “hold on,” all within sight of Officer Moseley
    who was detaining Mr. Banks. At this point, Officer Olszak
    had “accost[ed]” Appellant and “restrain[ed] his freedom.”
    Brown, 
    443 U.S. at 50
     (citation omitted). As the District Court
    found, no reasonable person in Appellant’s position and
    subject to Officer Olszak’s directives would have believed
    that he was free to go on about his business.
    13
    This conclusion is consistent with our precedent. Thus,
    for example, in Wood, we found that a show of authority
    occurred when a uniformed officer, at night, followed an
    individual into a dark entrance hallway of an apartment
    building and, positioning himself behind the individual,
    ordered, “[H]alt right there.” 981 F.2d at 540.
    A recent decision by the District of Columbia Court of
    Appeals, In re J.F., 
    19 A.3d 304
     (D.C. 2011), is also
    instructive, albeit not binding. In that case, two Metropolitan
    Police Department plainclothes officers who were wearing
    “Police” vests got out of an undercover car and approached an
    individual and his companion on a deserted street. 
    Id. at 306, 310
    . One of the officers ordered the individual to remove his
    hands from his pockets and then asked him some questions.
    
    Id. at 306
    . The other officer searched the individual’s
    companion and, when no contraband was found, detained that
    person while a warrant check was run. 
    Id. at 309-10
    . The
    court held that the individual who was instructed to remove
    his hands from his pockets was subject to a show of authority
    resulting in an illegal seizure. 
    Id. at 310
    ; see also Brodie, 742
    F.3d at 1060-61 (Government conceded a show of authority
    when two officers pulled their car parallel to a person on a
    sidewalk in front of townhomes and one officer “got out of
    the car and told [the individual] to put his hands on a nearby
    car”); United States v. Jones, 
    584 F.3d 1083
    , 1085, 1087
    (D.C. Cir. 2009) (Government conceded a seizure when an
    officer wearing a utility vest with the word “POLICE” on it
    got out of his car and, walking toward an individual who was
    among 15 or 20 people gathered throughout a block in what
    appeared to be “somewhat of a party atmosphere,”
    “instructed” the individual from a distance of less than 10 feet
    to “[c]ome here”).
    14
    The Government does not suggest that Officer Olszak’s
    actions did not amount to a show of authority. Rather, the
    Government argues that Appellant was not seized when
    Officer Olszak confronted him because “[A]ppellant
    continued walking without pausing when Officer Olszak said
    ‘hold on for a sec.’” Br. for Appellee at 24 n.17. The
    Government’s argument is disingenuous. The District Court
    found, based on Officer Olszak’s own testimony, that Officer
    Moseley, who “had detained Mr. Banks at the front of the
    house,” “‘took over’ the detention of Defendant.” United
    States v. Castle, 
    53 F. Supp. 3d 95
    , 99 (D.D.C. 2014). The
    trial judge thus credited Officer Olszak’s testimony that when
    Appellant continued walking after being told to stop, he was
    walking toward Officer Moseley and, according to Officer
    Olszak, was “‘not trying to go anywhere,’” but rather had
    “‘submitted.’” 
    Id. at 100
    . The Government does not contend
    that the District Court’s findings are clearly erroneous.
    It is hard to imagine a more submissive response to
    Officer Olszak’s directive to “hold on” given that, upon
    issuing it, Officer Olszak ran to the backyard, leaving
    Appellant unattended. Rather than attempting to evade Officer
    Moseley via the now clear path to Yuma Street, Appellant
    exhibited complete submission to police authority by walking
    directly to Officer Moseley. In sum, we reject the
    Government’s argument that the District Court erred in its
    conclusion as to when the seizure happened.
    B. Reasonable Articulable Suspicion
    Pursuant to the Fourth Amendment, a police officer who
    seizes a person on less than probable cause “must be able to
    point to specific and articulable facts which, taken together
    with rational inferences from those facts,” Terry, 392 U.S at
    21, support “a reasonable and articulable suspicion that the
    15
    person seized is engaged in criminal activity,” Reid v.
    Georgia, 
    448 U.S. 438
    , 440 (1980) (per curiam) (citing
    Brown, 
    443 U.S. at 51
    ). See also Ornelas, 
    517 U.S. at 696
    . It
    is the Government’s burden to provide evidence sufficient to
    support reasonable suspicion justifying any such stop. See
    Brown, 
    443 U.S. at 51-52
    ; see also Royer, 
    460 U.S. at 500
    .
    When reviewing a District Court’s reasonable, articulable
    suspicion assessment, we look, as does the District Court, to
    the totality of the circumstances, understanding that factors
    individually “susceptible to an innocent explanation” may
    “suffice[] to form a particularized and objective basis” when
    taken together. United States v. Arvizu, 
    534 U.S. 266
    , 277
    (2002). In considering the totality of the circumstances, it is
    “imperative” that we look only to “the facts available to the
    officer at the moment of the seizure.” Terry, 392 U.S. at 21-
    22; see also Ornelas, 
    517 U.S. at 696
    ; Sibron v. New York,
    
    392 U.S. 40
    , 64 (1968); Rios v. United States, 
    364 U.S. 253
    ,
    261-62 (1960) (facts discovered as a result of or subsequent to
    the seizure may not be considered). And we must assess those
    facts within an objective framework: “‘[T]he issue is whether
    a reasonably prudent man in the circumstances would be
    warranted in his belief’ that the suspect is breaking, or is
    about to break, the law.” Edmonds, 
    240 F.3d at 59
     (quoting
    Terry, 
    392 U.S. at 27
    ); see also United States v. McKie, 
    951 F.2d 399
    , 402 (D.C. Cir. 1991) (per curiam) (“[W]e . . .
    determine what facts were known to the officer and then
    consider whether a reasonable officer in those circumstances
    would have [had a reasonable, articulable suspicion].”).
    In undertaking this de novo review of a District Court’s
    “ultimate determination[]” that a seizing officer had the
    reasonable, articulable suspicion necessary to effectuate a
    particular stop, we must “take care both to review findings of
    historical fact only for clear error and to give due weight to
    16
    inferences drawn from those facts by resident judges and local
    law enforcement officers.” Ornelas, 
    517 U.S. at 697, 699
    .
    With respect to findings of historical fact, this means that we
    will find error if, looking to the entire record, we are
    definitely and firmly convinced that the trial court made a
    mistake. See Anderson v. City of Bessemer City, 
    470 U.S. 564
    ,
    573 (1985). With respect to inferences from those historical
    facts, the Supreme Court has instructed that when the
    inferences at issue are a police officer’s, “[a]n appeals court
    should give due weight to a trial court’s finding that the
    officer was credible and the inference reasonable.” Ornelas,
    
    517 U.S. at 700
    . But in assessing a trial court’s
    reasonableness determination, it is critical that we also keep in
    mind the Supreme Court’s admonition that “due weight must
    be given, not to [an officer’s] inchoate and unparticularized
    suspicion or ‘hunch,’ but to the specific reasonable inferences
    which he is entitled to draw from the facts in light of his
    experience.” Terry, 
    392 U.S. at 27
     (emphasis added); see also
    Wardlow, 
    528 U.S. at 123-24
    ; United States v. Sokolow, 
    490 U.S. 1
    , 7 (1989) (a “reasonable suspicion” requires “more
    than an inchoate and unparticularized suspicion or hunch”
    (citation omitted)). Moreover, an appellate court has the
    “power to correct errors of law, including those that may
    infect a so-called mixed finding of law and fact, or a finding
    of fact that is predicated on a misunderstanding of the
    governing rule of law.” Bose Corp. v. Consumers Union of
    U.S., Inc., 
    466 U.S. 485
    , 501 (1984); see also Inwood Labs.,
    Inc. v. Ives Labs., Inc., 
    456 U.S. 844
    , 855 n.15 (1982) (“[I]f
    the trial court bases its findings upon a mistaken impression
    of applicable legal principles, the reviewing court is not
    bound by the clearly erroneous standard.”).
    Finally, as noted above, and as particularly relevant to
    this case, the Fourth Amendment “does not allow police
    officers to ‘round up the usual suspects.’” Laughrin, 
    438 F.3d 17
    at 1247. Consequently, an officer relying on his or her “prior
    knowledge of [an individual’s] criminal record” is “required
    to pair” that knowledge “with some more ‘concrete factors’ to
    demonstrate that there [is] a reasonable suspicion of current
    criminal activity.” Foster, 
    634 F.3d at 247
     (emphasis added).
    This means that knowledge of an “individual’s criminal
    history [can] corroborate[],” but not substitute for,
    particularized, “objective indications of ongoing criminality.”
    Monteiro, 
    447 F.3d at 47
    .
    In this case, the Government argues that four
    circumstances support its contention that Officers Olszak and
    Moseley had the reasonable, articulable suspicion necessary
    to stop Appellant:
    (1) The officers’ knowledge that the neighborhood was
    a high-crime area particularly associated with PCP
    distribution.
    (2) The officers’ observation, while on patrol in their
    unmarked Dodge Ram truck, of Appellant walking
    quickly away from 133 Yuma Street (a building
    known for PCP distribution) and toward an
    abandoned house.
    (3) Appellant’s furtive movements in an alley next to
    the abandoned house.
    (4) The officers’ prior experience with Appellant, which
    included PCP-related arrests.
    See Br. for Appellee at 18-19. An additional fact cited by the
    Government – the odor of PCP that Officer Moseley noticed
    after he took over the detention of Appellant – is not
    cognizable because it was not known to the officers before
    18
    Officer Olszak seized Appellant. See Terry, 
    392 U.S. at
    21-
    22; United States v. Holmes, 
    360 F.3d 1339
    , 1345 (D.C. Cir.
    2004), vacated on other grounds, 
    543 U.S. 1098
     (2005).
    The lynchpin of any reasonable suspicion analysis in this
    case must be the second and third factors. The first factor –
    the high crime nature of the neighborhood – is not
    unimportant. But it is only a “contextual consideration[]” and,
    as such, cannot provide the kind of information particular to
    Appellant that is necessary to demonstrate reasonable
    suspicion. See Wardlow, 
    528 U.S. at 124
    . The fourth factor –
    the officers’ prior experience with Appellant – is particular to
    Appellant, but can only corroborate, not provide, the
    necessary, concrete indicia that Appellant was involved in
    criminal behavior when he was stopped.
    The Government argues that the second factor – walking
    quickly from the direction of an apartment building outside of
    which drugs could be bought toward an abandoned house –
    supports reasonable, articulable suspicion because the District
    Court concluded that it was not unreasonable for the officers
    to perceive Appellant’s behavior as an “evasion of the
    police.” Br. for Appellee at 20 & n.14; see also id. at 24-25,
    27-28, 27 n.19. The Government additionally points to
    Appellant’s bend and leg lift near the U-Haul, describing it as
    a furtive movement that “occurred immediately after” and “in
    response to” Appellant having “spied the police.” Id. at 21;
    see also id. at 21-22, 22 n.16. The Government thus
    acknowledges that the probative value of these two
    circumstances rests on the District Court’s conclusion that “it
    was not unreasonable for the officers to believe Defendant
    knew or suspected their [unmarked Dodge Ram] was a police
    vehicle.” Castle, 53 F. Supp. 3d at 100. Because the record is
    devoid of the sort of evidence necessary to support this
    19
    conclusion, the Government’s argument in support of
    reasonable suspicion necessarily collapses.
    The critical role that a possible suspect’s knowledge of
    police presence plays in determining whether arguably
    evasive action can be part of the totality of the circumstances
    supporting reasonable suspicion was made clear by the
    Supreme Court in Wardlow, 
    528 U.S. at 123-24
    . In that case,
    the Court held that, at least in areas of heavy narcotics
    trafficking, “[h]eadlong” flight is probative of wrong doing if
    it is both unprovoked and a result of “noticing the police.” 
    Id. at 124
    . In a similar vein, we have repeatedly emphasized that
    “furtive gestures are significant” in a reasonable, articulable
    suspicion analysis “only if they were undertaken in response
    to police presence, [a]nd a suspect can respond to the
    presence of a police officer only if he has recognized him as
    an officer.” Brown, 
    334 F.3d at 1168
     (alteration in original)
    (emphasis added) (citation omitted); see also Edmonds, 
    240 F.3d at 61
    ; Johnson, 
    212 F.3d at 1316
    .
    In support of its conclusion that Officers Olszak and
    Moseley reasonably believed that Appellant was aware of
    their presence in an unmarked truck and was acting to evade
    them, the District Court explained:
    [A]s the officers drove down Yuma Street, they saw
    Defendant walking very quickly from the direction of
    133 Yuma Street, an address known for PCP
    distribution and criminal activity, toward a vacant
    backyard area, suggesting to the officers that he was
    trying to evade their presence. The officers testified
    credibly that they patrolled the area so regularly that
    people in the neighborhood had come to recognize
    their vehicle and to expect such patrols. Indeed,
    Officer Olszak testified that people in the
    20
    neighborhood would act as “lookouts” and alert
    others to the presence of the police when they arrived
    in the area. Furthermore, the street ended in a cul de
    sac, meaning that non-police traffic was less likely
    than on another street. Therefore, it was not
    unreasonable for the officers to believe Defendant
    knew or suspected their vehicle was a police vehicle
    and was walking quickly in order to evade them.
    Castle, 53 F. Supp. 3d at 100 (emphases added). There are
    multiple problems with this analysis.
    First, the District Court’s factual finding that “people in
    the neighborhood” could recognize their truck as a police
    vehicle is questionable because it is based, at least in part, on
    specious testimony and speculation. Can anyone really take
    seriously Officer Olszak’s assertion that he and Officer
    Moseley drove “the only Dodge Ram in the city”? Tr. of
    Motions Hearing at 75. And there was little evidence to
    suggest that the truck was otherwise particularly distinctive.
    There was nothing to suggest that the silver color of the truck
    was unique. And there is little reason to suppose that the
    truck’s Florida license plates – the only arguably distinctive
    feature testified to by the officers – could be seen from any
    sort of distance, especially in the evening. Finally, we cannot
    help but note that the Government “did not seek to qualify
    [the police officers] as . . . expert[s] on public identification of
    police vehicles” or “establish a factual foundation for opinion
    testimony as [lay witnesses].” See Johnson, 
    212 F.3d at 1316
    .
    In other words, there are good reasons to question the District
    Court’s factual finding that “people in the neighborhood”
    readily recognized the truck as a police vehicle.
    But, even accepting this dubious assertion as not clearly
    erroneous, we are nonetheless convinced that the District
    21
    Court erred in equating the awareness of “people in the
    neighborhood” that the unmarked truck the officers drove was
    a police vehicle with a determination that the officers could
    reasonably believe that Appellant was aware of the officers’
    truck on the evening in question. The Government simply
    failed to put any evidence into the record that would support a
    reasonable officer in inferring that the indicia of police
    presence (the truck) had come to the attention of Appellant,
    let alone that Appellant reacted to the truck as a police
    vehicle.
    In the face of this gap in the evidentiary record, the
    District Court’s assessment of the reasonableness of the
    officers’ inference amounts to a classic non sequitur. It does
    not follow from the fact that the unmarked truck was known
    in neighborhood as a police vehicle that Appellant was aware
    of its presence on the evening of his seizure and that the
    behavior witnessed by the officers was a reaction to that
    presence. Thus, the trial court’s determination that the officers
    reasonably inferred that Appellant was evading them is due
    no weight. The failure of the Government to provide any
    evidence supporting the officers’ inferences that Appellant
    knew of their presence and was acting in response to it should
    have led the trial court to find that these were not the sort of
    “specific reasonable inferences which [the officers were]
    entitled to draw from the facts in light of [their] experience,”
    but rather amounted to no more than “inchoate and
    unparticularized suspicion[s] or ‘hunch[es]’” to which no
    deference is owed. Terry, 
    392 U.S. at 27
    .
    The District Court’s assessment also defies legal
    authority. Our precedent makes clear, no matter how widely
    and readily recognizable the truck may have been as a police
    vehicle, a different type of evidence was necessary to support
    the inference that Appellant knew the police truck was present
    22
    and was responding to it. When putative police evasion or an
    alleged furtive gesture is what provokes police suspicion, our
    precedent requires that the Government proffer evidence,
    apart from that behavior or gesture, from which an officer
    could reasonably have inferred that the individual in question
    was aware of the recognizable police presence and was
    responding to it. See Brown, 
    334 F.3d at 1168
    ; Johnson, 
    212 F.3d at 1316-17
    .
    Our decision in Edmonds is instructive with respect to the
    sort of evidence that is necessary. There, as here, officers
    were driving an undercover car, a Crown Victoria that the
    seizing officer, Sergeant Feirson, testified was “regularly used
    to patrol the neighborhood and is easily identifiable by
    residents as a police cruiser.” 
    240 F.3d at 57
    . As the officers
    made their way through the neighborhood in question, an area
    “notorious as [an] open air drug market[],” Feirson testified
    that he saw a man standing on the curb. 
    Id.
     According to
    Feirson, when the man looked at the unmarked cruiser, ‘“his
    eyes got pretty big, and he immediately pivoted, turned away
    and he began to walk’ – rapidly – towards a van located in the
    parking lot of [a] nearby . . . school.” 
    Id.
     The school was
    closed, and the parking lot was a known site for drug
    transactions. 
    Id.
     There was someone sitting in the driver’s seat
    of the van when the man entered it. 
    Id.
     The man “had left the
    curb, Feirson believed, because he had recognized him and
    his companions as police officers.” 
    Id.
    At this point, Sergeant Feirson decided to investigate. He
    got out of the unmarked car and, with his police badge
    prominently hanging from his neck, approached the van from
    the front looking through the windshield. See 
    id.
     The Sergeant
    could see both the driver and the man who he believed had
    recognized him as a police officer through the van’s
    windshield, and as he drew nearer, he saw the driver lean
    23
    forward making gestures that led Feirson to believe the driver
    was hiding something. See 
    id.
     A seizure of the driver
    eventually led to the discovery of a gun under his seat. 
    Id.
    In undertaking a reasonable suspicion analysis, we
    considered both the furtive gestures of the driver and his
    passenger’s “apparent attempt to evade the officers” when he
    left the curb. 
    Id. at 60
    . And with respect to both, we had
    evidence from which Feirson could not only reasonably infer
    that he had been recognized as a police officer, but also
    evidence allowing Feirson to reasonably conclude that his
    being a police officer had come to the attention of both men
    and that their respective actions were in response to that
    recognition. Thus, with respect to the man on the curb, there
    was testimony that the undercover car was well known in an
    area notorious for drug sales. But in addition, Feirson testified
    that the man looked at the Crown Victoria and that
    “immediately upon observing” it, his eyes got big and he
    “hastened to the van to join its driver.” 
    Id. at 62
    ; see also 
    id. at 57
    . We found that “it was reasonable for Feirson’s
    suspicions to be aroused in the first instance by [the man’s]
    apparent flight and retreat” “immediately upon observing that
    [known police] vehicle.” 
    Id. at 62
    . And we were satisfied that
    because the Sergeant could see the driver “through the van’s
    windshield, it [was] a fair inference that [the driver] in turn
    saw Feirson, perceived his badge, recognized him as a police
    officer, and reacted by making furtive gestures.” 
    Id.
    The Wardlow opinion, addressing flight from the police,
    references similar evidence. There, it appears that the fact that
    the suspect had seen the police before he fled was never
    challenged. Nonetheless, the Supreme Court described the
    evidence from which it could reasonably be inferred that the
    officers from whom Wardlow fled were recognizable as
    police, that Wardlow was aware of their presence, and that his
    24
    flight was in response to that presence. The Court explained
    that the seizing officers, who were in uniform, were driving
    the last car of a four-car police caravan that was converging
    on an area known for heavy drug trafficking. 
    528 U.S. at 121
    .
    As the caravan passed Wardlow, one of those officers
    observed him “look[] in the direction of the officers” and then
    flee. 
    Id. at 121-22
    .
    In this case, the Government presented not an iota of
    similar evidence at either the motions hearing or during the
    trial. The officers simply failed to provide the trial judge with
    any testimony from which she could conclude that an
    objective officer in possession of the information Officers
    Olszak and Moseley had could reasonably or fairly infer that
    Appellant was aware of the police truck and was acting in
    response to it. As noted above, there was no testimony that
    either Appellant or the man with him ever so much as glanced
    in the direction of the truck – let alone reacted to it. The
    officers never testified, nor was there any factual finding, that
    either man turned his head toward the truck or pointed or
    gestured at it. Neither was there evidence that either man’s
    pace or gait changed as the officers turned onto and drove
    down the street. In fact, Officer Moseley expressly testified
    that the men were already walking quickly when he saw them
    and pointed them out to Officer Olszak. Nor did the officers
    testify that either man changed direction or that Appellant
    altered the path he was on in order to enter the alleyway
    between the two houses. Neither officer even suggested that
    the men were ever, at any point, oriented so that they faced
    the truck as they walked. Indeed, because 144 Yuma is a
    higher numbered address than 133 Yuma, the testimony
    suggests that the men were oriented somewhat toward the cul-
    de-sac, walking diagonally away from the truck as it came
    from the intersection of First and Yuma Streets.
    25
    Furthermore, there is no evidence to indicate that the
    physical circumstances during the evening in question would
    have permitted Appellant to recognize the truck even if he had
    looked in its direction. Quite the contrary. The officers
    testified that: when the truck turned onto Yuma Street,
    Appellant and the truck were at opposite ends of a long city
    block; the truck’s headlights were on and pointed in
    Appellant’s direction – something that would not have
    changed as the officers drove down the street and that would
    have made it very difficult to identify a Florida license tag
    even as the truck moved closer to the cul-de-sac; and the truck
    was silver, not a color that would stand out, whether it was
    “dark,” as the trial judge found, Castle, 53 F. Supp. 3d at 98,
    or “the dusk hour” with some street lights illuminated, as the
    officers testified, see Tr. of Trial at 88, 109 (July 16, 2014).
    Moreover, Officers Olszak and Moseley provided no
    testimony from which they could reasonably infer that
    someone else who recognized the truck had alerted Appellant.
    Thus, unlike Edmonds, where a man on the street clearly
    noticed the undercover Crown Victoria and then pivoted and
    hastened over to the defendant, there was no testimony in this
    case that anyone on Yuma Street noticed the Dodge Ram and
    then approached or otherwise alerted Appellant or the man
    with him. And while Officer Olszak testified that the
    passenger side window of the truck was rolled down as
    Officer Moseley turned onto Yuma Street, neither he nor
    Officer Moseley said that they heard anyone yelling out “J.O.
    J.O.” or any other calls or signals that experienced officers
    would have recognized as ones typically used by those
    involved in illegal narcotics sales when they wish to alert
    others to the presence of jump outs or undercover officers.
    Nor, apparently, did the officers do anything to attract
    Appellant’s attention as they drove down Yuma Street. There
    26
    was no testimony, for example, that they activated the truck’s
    internal police lights, about which they testified, or otherwise
    announced their arrival in order to confirm or dispel their
    unsupported hunch that Appellant was walking quickly in an
    effort to evade them.
    During oral argument before this court, Government
    counsel asserted that there was evidence that the Appellant
    and the truck were at some point in such close proximity that
    it would have been reasonable for the officers to infer that
    Appellant recognized the truck and responded by walking into
    the alleyway. See Recording of Oral Arg. 33:55-36:00. In
    other words, the Government essentially suggested that we
    look to the record for evidence apart from the District Court’s
    findings of fact, that might support the conclusion that the
    officers could reasonably infer that Appellant was aware of
    and reacting to the truck’s presence. As noted earlier, the law
    does not permit us to do this. See Bailey, 
    622 F.3d at
    5 n.1.
    More fundamentally, Government counsel pointed to no
    record evidence to support this assertion, and cited none in its
    brief. Moreover, we can locate none in the motions hearing or
    trial records. Most importantly, the Government’s argument is
    belied by Officer Moseley’s uncontradicted trial testimony
    that, “[b]y the time we got to the corner of 144 Yuma Street
    when I stopped the truck, Mr. Castle was pretty close to the
    U-Haul,” Tr. of Trial at 61 (July 16, 2014); see also Tr. of
    Motions Hearing at 26, which was about 125 feet from the
    street, Tr. of Motions Hearing at 87.
    In its brief to this court, the Government repeatedly,
    broadly asserts that Appellant walked quickly toward 144
    Yuma, into an alleyway between 144 Yuma and the house
    next door, and made furtive gestures, all “upon recognizing”
    or “in response to” or “immediately after he spied” the police.

    But the Government cites no record evidence in support of
    these assertions. Rather, the Government relies on the District
    Court’s conclusion that the officers reasonably inferred that
    Appellant was “walking quickly in order to evade them,” see
    
    id.
     at 20 n.14; see also 
    id.
     at 22 n.16 (referencing the District
    Court’s conclusion that the officers reasonably inferred that
    Appellant bent down near the U-Haul and made a kicking
    movement with his leg in response to a known police
    presence). As explained above, the District Court’s
    conclusion about what the officers could reasonably infer is
    without support in the record, contrary to governing
    precedent, and inconsistent with the dictates of logic.
    Consequently, it is due no weight.
    During oral argument, in an effort to bolster its claim that
    Appellant was aware of the officers’ presence, Government
    counsel also pointed us to two statements made by Officer
    Olszak. On direct examination, Officer Olszak testified: “We
    saw two guys towards the end of the street to the right kind of
    speed walk across the street. They were walking faster than at
    a normal pace when they made us out.” Tr. of Motions
    Hearing at 22. Later on cross examination, Officer Olszak
    similarly asserted: “I think they knew we were the police
    when we first pulled in the block.” 
    Id. at 60
    . However, on
    further cross examination, Officer Olszak clarified that his
    assertion that Appellant “knew we were the police” was based
    solely on his conclusion that the unmarked truck was well
    known in the community as a police vehicle. 
    Id. at 60-61
    .
    Officer Olszak then admitted that he had no other evidence
    supporting his suspicion that Appellant and the man with him
    knew that there was a police truck on Yuma Street. See 
    id. at 61
    . Given this testimony, it is hardly surprising that the
    District Court did not cite the officer’s unsupported assertions
    that Appellant “made out” or recognized the officers or their
    truck. Rather, the District Court relied solely on the officers’
    28
    testimony that their truck was well known in the
    neighborhood as a police vehicle. Then, based solely on the
    fact of neighborhood awareness that the truck was a police
    vehicle, the trial judge reached the implausible conclusion
    that the officers could reasonably infer that Appellant was
    aware of the truck’s presence on Yuma Street on the evening
    in question and was responding to it. This conclusion is
    contrary to the facts in this case and to well-established law.
    For the reasons explained above, we are constrained to
    reverse because the police officers had no reasonable,
    articulable suspicion justifying their stop of Appellant. See,
    e.g., Sprinkle, 
    106 F.3d at 617-19
     (an individual’s presence in
    a neighborhood known for drug crimes, “huddl[ing]” with
    another person in a manner suggestive to the officers of a
    drug sale, and the individual’s effort to hide his face and
    “dr[i]ve away as soon as the officers walked by” did not
    provide indicia of criminal activity adequate to support
    reasonable, articulable suspicion even when combined with
    the officers’ knowledge of the individual’s prior criminal
    record for narcotics offenses).
    CONCLUSION
    The judgment of the District Court is reversed and the
    case is hereby remanded for further proceedings consistent
    with this opinion.
    So ordered.
    SILBERMAN, Senior Circuit Judge, dissenting: In my view,
    the majority opinion is quite unfortunate. It not only breaks with
    circuit precedent, it is quite confusing regarding the appropriate
    scope of review we should apply in reviewing district court
    factual determinations – particularly inferences drawn from
    historical facts.
    To be sure, the overall question whether Officer Olszak had
    a reasonable suspicion to stop the Appellant is a question of law,
    although we must keep in mind it is deferential to officers
    because it asks only whether their actions are reasonable as
    police officers in light of their training and experience, not
    whether judges, putting themselves in the same position, would
    regard the actions of the defendant as suspicious. (Indeed, even
    our cases relied on by the majority uniformly affirm district
    courts’ approval of investigative stops.) But – and this is a
    crucial point – subordinate determinations of historical facts as
    well as inferences from those historical facts are fact-findings
    for the district judge. See Ornelas v. United States, 
    517 U.S. 690
    , 699 (1996) (“We hold as a general matter determinations
    of reasonable suspicion . . . should be reviewed de novo on
    appeal. Having said this, we hasten to point out that a reviewing
    court should take care both to review findings of historical fact
    only for clear error and to give due weight to inferences drawn
    from those facts by resident judges and local law enforcement
    officers.” (emphasis added)).
    At the outset, I think even the undisputed facts in this case
    support the district court’s determination that Officer Olszak had
    a reasonable suspicion justifying the seizure of Appellant Castle.
    Those facts are:
    1.   The officers knew that the 100 block of Yuma Street
    was a site of significant PCP distribution and use.
    2.   The officers patrolled the area three or four times a
    week in an unmarked – though distinctive – pickup
    2
    truck with Florida license plates. They testified
    (credibly, according to the district judge) that they
    patrolled the area so regularly that neighborhood
    people recognized their vehicle and some people would
    actually act as lookouts.
    3.   Appellant and a companion were walking at a fast pace
    from 133 Yuma Street, an address known for PCP
    distribution and criminal activity.
    4.   Appellant continued to walk down a narrow alley next
    to an abandoned house and bent over with one leg up
    in the air, sort of a backward kick, apparently in the
    manner as if one were dropping something, behind a
    U-Haul vehicle (what the majority refers to as “furtive
    movements”).
    5.   Then Appellant inexplicably walked back out of the
    alley, toward the officer, at which point Officer Olszak
    recognized him. Officer Olszak had seen Appellant
    “hang[ing] out” in front of 133 Yuma with known PCP
    dealers on a number of previous occasions, and he
    recalled several prior PCP-related arrests and incidents
    involving Appellant, including multiple occassions on
    which Appellant had attempted to evade arrest by
    fleeing from the police and to destroy evidence of PCP
    distribution and possession by pouring it on the
    ground.
    See United States v. Castle, 
    53 F. Supp. 3d 95
    , 99-101 (D.D.C.
    2014).
    To justify a Terry stop, an officer need only “observe[]
    unusual conduct which leads him reasonably to conclude in light
    3
    of his experience that criminal activity may be afoot.” Terry v.
    Ohio, 
    392 U.S. 1
    , 30 (1968). The undisputed facts alone satisfy
    Terry’s standard. Appellant’s conduct was quite unusual; it is
    not commonplace to walk into an alley leading to a vacant
    backyard, lean over behind an abandoned vehicle with one leg
    raised as if to drop something (or pick something up), and then
    immediately turn around and come back (notwithstanding the
    majority’s assertion that it is “commonplace,” Majority Op. at
    5). In any event, even relatively “normal” activity can be
    sufficient to arouse an officer’s suspicions. “A determination
    that reasonable suspicion exists . . . need not rule out the
    possibility of innocent conduct.” United States v. Arvizu, 
    534 U.S. 266
    , 277 (2002). The suspicious conduct in Terry, for
    example, consisted only of men walking up and down a block
    several times, looking into a store window. 392 U.S. at 5-6.
    The Court carefully distinguished the arrest standard – probable
    cause that a crime has been committed – from the lower
    standard of reasonable suspicion necessary for an investigative
    stop.1 Id. at 26.
    The majority, nevertheless, asserts that Appellant’s activity
    was “entirely mundane” and “not suspicious,” (presumably as a
    matter of law?), Majority Op. at 5, but it reaches that conclusion
    by examining each factor alone without considering the effect
    1
    While the analysis and holding in United States v. Edmonds is
    consistent with my view of this case, our opinion includes a stray
    comment suggesting Terry requires a belief that “the suspect is
    breaking, or is about to break, the law.” 
    240 F.3d 55
    , 59 (D.C. Cir.
    2001). But that is an overstatement. All Terry requires is that the
    officer suspect “criminal activity may be afoot.” 392 U.S. at 30
    (emphasis added). It is the probable cause standard that requires belief
    that a crime has been, is being, or is about to be committed. Id. at 26;
    id. at 35 (Douglas, J., dissenting).
    4
    when they are all combined. While each individual factor may
    be “susceptible of innocent explanation, and some factors are
    more probative than others[, t]aken together,” Arvizu, 
    534 U.S. at 277
    , they can suffice to form the particularized and objective
    basis required by Terry. See also United States v. Sokolow, 
    490 U.S. 1
    , 8 (1989) (“In evaluating the validity of a [Terry]
    stop . . . , we must consider ‘the totality of the circumstances –
    the whole picture.’” (quoting United States v. Cortez, 
    449 U.S. 411
    , 417 (1981)). The additional circumstances here do just
    that.
    First, the stop occurred in a high-crime area. The majority
    discounts this factor by noting that the high-crime nature of a
    neighborhood is merely a “contextual consideration[]” that
    cannot demonstrate reasonable suspicion. Majority Op. at 18.
    But “officers are not required to ignore the relevant
    characteristics of a location in determining whether the
    circumstances are sufficiently suspicious to warrant further
    investigation.” Illinois v. Wardlow, 
    528 U.S. 119
    , 124 (2000).
    I do not disagree that location alone cannot be determinative,
    but it can be used in conjunction with other factors – such as the
    Appellant’s odd behavior – to establish reasonable suspicion, as
    is the case here.
    What is more, once Officer Olszak recognized Appellant,
    Castle’s behavior that night – walking quickly from the PCP
    house down the alley, bending over as if he was dropping
    something, and then turning around and walking back toward
    Officer Olszak – looked particularly suspicious in light of his
    history. Officer Olszak knew Appellant hung around the PCP
    house with known PCP dealers, and knew Appellant had several
    prior PCP-related arrests, including incidents in which Appellant
    attempted to evade police and destroy evidence. At that point,
    it was not unreasonable for Officer Olszak to infer Appellant’s
    5
    odd behavior was consistent with how he had behaved in the
    past when in possession of PCP. See United States v. Feliciano,
    
    45 F.3d 1070
    , 1074 (7th Cir. 1995) (holding that “recent
    relevant criminal conduct . . . is a permissible component of the
    articulable suspicion required for a Terry stop,” and collecting
    cases to that effect).
    Again, the majority discounts this factor as merely
    corroborative, Majority Op. at 18, but that is exactly how
    Officer Olszak used this piece of information. His suspicions
    were not aroused solely because of Appellant’s criminal history
    (he was not “round[ing] up the usual suspects,” id. at 16
    (quoting United States v. Laughrin, 
    438 F.3d 1245
    , 1247 (10th
    Cir. 2006)), but because of that criminal history in the context of
    the current situation: Olszak observed a man whom he knew had
    previously been arrested for PCP-related crimes, who attempted
    to destroy evidence and flee from police, quickly walk away
    from a building known for PCP distribution, down a deserted
    alley to a vacant lot, and appear to drop something behind an
    abandoned U-Haul truck, then immediately turn around and
    come back. Compare United States v. Gordon, 
    722 F.2d 112
    ,
    114 (5th Cir. 1983) (per curiam) (reasonable suspicion to stop a
    motor home existed where officers identified driver as a member
    of a drug smuggling group, knew the motor home was registered
    to the same address as a motor home seized in an earlier drug
    arrest, and knew the group’s smuggling operations involved the
    use of motor homes). In other words, Officer Olszak did in fact
    “pair . . . knowledge [of the Appellant’s criminal record] with
    some more concrete factors to demonstrate that there [is] a
    reasonable suspicion of current criminal activity.” Majority Op.
    at 17 (quoting United States v. Foster, 
    634 F.3d 243
    , 247 (4th
    Cir. 2011)) (internal quotation marks omitted) (third alteration
    in original).
    6
    The majority emphasizes that Appellant’s actions cannot be
    construed as furtive unless the government shows that Appellant
    and his companion recognized the police vehicle before
    Appellant walked down the alley. I think Appellant’s actions,
    paired with the circumstances, were unusual enough that
    reasonable suspicion existed regardless of whether the actions
    were prompted by knowledge of police presence, for the above
    reasons.
    However, even were evidence of Appellant’s recognition of
    police presence necessary to satisfy Terry, that standard is met
    here. The majority insists the government did not provide
    sufficient evidence, describing a great number of hypothetical
    pieces of evidence that would more clearly demonstrate
    Appellant or his companion recognized the officers’ presence.
    Majority Op. at 4-5, 24-26. I concede the government made no
    showing that Appellant (or anyone else) pulled out a megaphone
    and announced to the neighborhood “J.O. J.O.,” or anything of
    that nature. But the government showed “a sufficient basis for
    the officers to believe they had been recognized.” See United
    States v. Brown, 
    334 F.3d 1161
    , 1168 (D.C. Cir. 2003). While
    that may sometimes take the form of very direct, clear evidence
    – the police announcing themselves, as in United States v.
    Johnson, 
    212 F.3d 1313
    , 1315 (D.C. Cir. 2000), or officer
    testimony that the individual’s eyes grew large at the sight of
    police, as in United States v. Edmonds, 
    240 F.3d 55
    , 57 (D.C.
    Cir. 2001), for example – as the majority seems to demand here,
    that is not always the case.
    The majority’s own authority makes that point. In Brown,
    for example, the only evidence the government had of
    knowledge of police presence was circumstantial – the police
    were in uniform, their car was marked, another passenger had
    exited the vehicle several minutes prior, and one officer carried
    7
    a lit flashlight as he approached – and the court acknowledged
    that the “furtive movements” the officers observed could have
    been “merely a coincidence.” 
    334 F.3d at 1168
    . After all, there
    was no evidence the vehicle’s occupants actually had observed
    these facts (indeed, they allegedly were distracted by “amorous
    activity,” 
    id.
     at 1168 n.5). Nevertheless, we held that “the
    possibility of such a coincidence d[id] not negate the officers’
    reasonable suspicion and fear, nor d[id] the fact that the
    passenger’s behavior did not necessarily indicate criminal
    activity or prospective danger.” 
    Id. at 1168
    .
    So too here. There was sufficient circumstantial evidence
    to allow Officer Olszak to reasonably conclude his presence had
    been noted, and Appellant’s actions constituted suspicious
    “furtive movements.” The district court found that the officers’
    distinctive truck (with Florida license plates) was well-known in
    the neighborhood as a police vehicle, and that it was not unusual
    for people to act as lookouts and alert others to police presence.
    Additionally, traffic on Yuma Street is sparse given that it ends
    in a cul-de-sac, making the presence of any vehicle noticeable.
    In light of those circumstances, the district court concluded “it
    was not unreasonable for the officers to believe [Appellant]
    knew or suspected their vehicle was a police vehicle,” and that
    his walking “very quickly from the direction of 133 Yuma Street
    toward the vacant back yard area, sugges[ted] to the officers that
    he was trying to evade their presence.” Castle, 53 F. Supp. 3d
    at 100 (emphasis added). That is fact-finding based on
    inferences from the historical facts and bolstered by a credibility
    determination. The majority complains that “equating the
    awareness of ‘people in the neighborhood’ that the unmarked
    truck the officers drove was a police vehicle with a
    determination that the officers could reasonably believe that
    Appellant was aware of the officers’ truck on the evening in
    question,” is a “dubious assertion.” Majority Op. at 20-21. But
    8
    this is nothing more than the majority quarreling with an
    inference which the officers and the district court were entitled
    to draw, and we, as an appellate court, must respect.
    *****
    The important doctrinal point that divides me from the
    majority is the proper scope of review of the district court’s
    determination. It is black letter law that inferences drawn from
    historical fact are part and parcel of a district judge’s
    fact-finding – which may be disturbed by an appellate court only
    on a determination of clear error. In my view, the majority
    improperly cloaks an attack on the district judge’s fact-finding
    as a question of law. Compounding the problem, the majority
    refuses to say exactly what kind of error it has supposedly
    identified, instead declaring the district court’s conclusion
    “without support in the record” (suggesting clear factual error),
    “contrary to governing precedent” (suggesting legal error), “and
    inconsistent with the dictates of logic” (suggesting some other
    type of error entirely?). Majority Op. at 27. Thus, the majority
    at pages 5-6 and 9-10 conflates the roles of the police officer,
    the district judge, and the court of appeals. The overall question
    as to whether the officer’s stop of an individual is reasonable is
    clearly a question of law – but it is a question of law over which
    the district court and we defer to the police officer’s inferences.
    Subordinate to that overall legal question are questions of
    historical fact and inferences to be drawn from those facts. As
    an appellate court we must respect the district court’s resolution
    of those questions unless there is clear error. Ornelas, 
    517 U.S. at 699-700
    .
    The result of the court’s opinion, I fear, will be immense
    confusion on the part of district courts attempting to interpret
    9
    and apply this Delphic – and seemingly inconsistent with circuit
    precedent – opinion. I respectfully dissent.
