    COMMONWEALTH OF PENNSYLVANIA                         IN THE SUPERIOR COURT
    OF
    PENNSYLVANIA

    v.
    STEPHEN MACKEY
    Appellant                  No. 1460 EDA 2015
    Appeal from the Judgment of Sentence April 13, 2015
    In the Court of Common Pleas of Philadelphia County
    Criminal Division at No(s): CP-51-CR-0010023-2014
    BEFORE: BOWES, J., MOULTON, J., and STEVENS, P.J.E.*
    OPINION BY MOULTON, J.:                            FILED DECEMBER 20, 2017
    Stephen Mackey appeals from the April 13, 2015 judgment of sentence
    entered in the Court of Common Pleas of Philadelphia County following his
    convictions for persons not to possess a firearm, carrying a firearm without a
    license, and carrying a firearm on the public streets of Philadelphia.1 While
    we acknowledge the significant challenges presented by the facts in this case,
    we conclude that under controlling precedent the police lacked reasonable
    suspicion to detain Mackey. Accordingly, we overturn the trial court’s denial
    of Mackey’s motion to suppress and vacate the judgment of sentence.

    J-S81029-16
    This case involves a recurring scenario – the police receive an
    anonymous tip that a person matching a particular description in a particular
    location is carrying a firearm. When such a tip appears to raise a legitimate
    concern for public safety, the police have a manifest obligation to treat it
    seriously. As Judge Bowes aptly notes in her concurring opinion, “‘[i]t would
    have been poor police work indeed’ for the officers to simply ignore the tip
    just because possession of a firearm is not per se illegal.      Conc. Op. at 5
    (quoting Terry v. Ohio, 
    392 U.S. 1
    , 23 (1968). At the same time, in light of
    the tipster’s cloak of anonymity, the police must also account for the possibility
    that the tip is either in error or, worse, a sham designed to cause trouble for
    a person who is not carrying a weapon. In responding to such a tip, therefore,
    as in countless other recurring situations, the police must balance their
    obligation to protect the public from danger with their constitutional duty to
    respect the rights of all citizens.      Striking that balance is particularly
    challenging when the safety concern, while significant, is based not on police
    observations but solely on the unverified allegations of a person who cannot
    be held to account if those allegations prove false.
    The essential facts in this case, developed at a hearing on Mackey’s
    motion to suppress, are largely undisputed. Philadelphia Police Officer Marcus
    O’Shaughnessy testified that on July 23, 2014, while on routine patrol, he
    received a radio call for a “person with a gun” aboard the Route 3 SEPTA bus,
    number 8323, traveling eastbound on Cecil B. Moore Avenue. According to
    the call, the suspect was described as “a black male wearing a white T-shirt
    -2-
    J-S81029-16
    and a flowered hat.” N.T., 2/9/15, at 10. Officer O’Shaughnessy, along with
    another officer, found, stopped, and boarded the bus within two minutes of
    receiving the radio call. The trial court described what happened on the bus
    as follows:
    Officer O'Shaughnessy entered the bus, which was
    filled with 50 to 60 passengers, and he immediately
    observed [Mackey] wearing a pink-and-green-flowered hat
    and a shirt that was white on the back and black on the
    front.2 (See N.T. 02/09/15, pp. 5-12, 16-17).
    2   Officer O’Shaughnessy described the flowered hat
    as extremely distinctive in that it was a “bucket”
    hat patterned with pink and green flowers. (See
    N.T. 02/09/15, p. 17).
    Officer O’Shaughnessy testified that he drew his
    firearm and commanded that [Mackey] show his hands;
    [Mackey] complied. He described [Mackey] as sitting up
    straight, while all the other passengers were leaning away
    and trying to duck for cover. [Mackey] was then handcuffed
    and led off the bus for passenger as well as officer safety.
    [Mackey] denied having any weapons; however, as he was
    being led off the bus, [Mackey] was not walking normally,
    he was “waddling”.        Officer O’Shaughnessy observed
    [Mackey] waddling for 20 to 25 feet. He testified that in his
    experience as an officer, he believed that [Mackey] was
    trying to keep a gun from falling out of his loose-fitting
    pants. Officer O’Shaughnessy then frisked [Mackey] and
    felt the gun, which he recovered from [Mackey’s] waistband.
    The gun, which was loaded, was secured under property
    receipt. The entire incident took less than five (5) minutes.
    (See N.T. 02/09/15, pp. 12-17).
    Trial Court Opinion, 12/24/15, at 2-3 (“1925(a) Op.”) (some internal citations
    omitted).
    The trial court denied the motion to suppress, concluding that Officer
    O’Shaughnessy had properly removed Mackey from the bus out of a concern
    -3-
    J-S81029-16
    for public safety and that, based on a combination of the detailed tip, Mackey’s
    response to the officer drawing and pointing his service weapon, and Mackey’s
    “waddling” off the bus, the officer had reasonable suspicion to frisk Mackey
    for weapons. 1925(a) Op. at 6. Mackey proceeded to a non-jury trial on
    stipulated facts, after which the trial court convicted him of the offenses listed
    above. On April 13, 2015, following a pre-sentence investigation, the trial
    court sentenced Mackey to 2 to 5 years’ incarceration, followed by 3 years’
    probation on the conviction for persons not to possess a firearm. The court
    imposed no further penalty on the remaining convictions.            Mackey filed a
    timely notice of appeal on May 11, 2015.
    Mackey raises the following issues on appeal:
    A. Did law enforcement detain . . . Mackey without the required
    reasonable suspicion?
    B. Did law enforcement subject           .   .   .   Mackey   to   a
    constitutionally infirm frisk?

    In reviewing the denial of a suppression motion, our role is to determine:
    whether the suppression court’s factual findings are
    supported by the record and whether the legal conclusions
    drawn from those facts are correct.            Because the
    Commonwealth prevailed before the suppression court, we
    may consider only the evidence of the Commonwealth and
    so much of the evidence for the defense as remains
    uncontradicted when read in the context of the record as a
    whole. Where the suppression court’s factual findings are
    supported by the record, we are bound by these findings
    and may reverse only if the court’s legal conclusions are
    erroneous. Where, as here, the appeal of the determination
    of the suppression court turns on allegations of legal error,
    the suppression court’s legal conclusions are not binding on
    -4-
    J-S81029-16
    an appellate court, whose duty it is to determine if the
    suppression court properly applied the law to the facts.
    Thus, the conclusions of law of the courts below are subject
    to our plenary review.
    Commonwealth v. Jones, 
    988 A.2d 649
    , 654 (Pa. 2010) (internal quotations
    and citations omitted).    Our scope of review is limited to the evidence
    presented at the suppression hearing. In re L.J., 
    79 A.3d 1073
    , 1080 (Pa.
    2013).
    Mackey first alleges that he was illegally detained because Officer
    O’Shaughnessy lacked reasonable suspicion to believe Mackey was carrying a
    weapon.     According to Mackey, at the moment of detention, Officer
    O’Shaughnessy lacked reasonable suspicion to seize him because the officer
    possessed only anonymous radio information that a person partially matching
    Mackey’s appearance was armed, and the officer “did not observe any criminal
    activity to corroborate the radio call.” Mackey’s Br. at 5, 10.
    The Commonwealth responds that “the totality of the circumstances
    established reasonable suspicion to believe that criminal activity might be
    afoot.”    Cmwlth.’s Br. at 8.      The Commonwealth notes that Officer
    O’Shaughnessy received a detailed tip that described Mackey’s appearance,
    as well as information that he was on a specific bus headed eastbound on Cecil
    B. Moore Avenue. 
    Id. In addition
    to the tip, the Commonwealth relies on
    Mackey’s “unusual” behavior when Officer O’Shaughnessy drew his service
    weapon and Mackey’s “waddling” off the bus in support of its claim that the
    officer reasonably believed Mackey was carrying a weapon. 
    Id. at 9.
    -5-
    J-S81029-16
    The investigation of possible criminal activity invariably brings police
    officers in contact with members of the public.               Depending on the
    circumstances, a police-citizen encounter may implicate the liberty and
    privacy interests of the citizen as embodied in both the federal constitution,
    see U.S. Const. art. IV,2 and our state constitution, see Pa. Const. art. I, §
    8.3   The law recognizes three distinct levels of interaction between police
    officers and citizens: (1) a mere encounter; (2) an investigative detention,
    often described as a Terry stop, see Terry v. Ohio, 
    392 U.S. 1
    (1968); and
    (3) a custodial detention. See Commonwealth v. Jones, 
    874 A.2d 108
    , 116
    (Pa.Super. 2005).

    2   The Fourth Amendment to the United States Constitution provides:
    The right of the people to be secure in their persons, houses,

    but upon probable cause, supported by Oath or affirmation,
    and particularly describing the place to be searched, and the
    persons or things to be seized.
    3 Our Supreme Court has held that “the Fourth Amendment [of the
    United States Constitution] and Article I, [Section] 8 [of the Pennsylvania
    Constitution] are coterminous for Terry [v. Ohio, 
    392 U.S. 1

    purposes.” Commonwealth v. Chase, 
    960 A.2d 108
    , 118 (Pa. 2008). Article

    “A mere encounter can be any formal or informal interaction between
    an officer and a citizen, but will normally be an inquiry by the officer of a
    citizen. The hallmark of this interaction is that it carries no official compulsion
    to stop or respond,” Commonwealth v. DeHart, 
    745 A.2d 633
    , 636
    (Pa.Super. 2000) (internal citations and quotations omitted), and therefore
    need not be justified by any level of police suspicion. Commonwealth v.
    Polo, 
    759 A.2d 372
    , 375 (Pa. 2000).
    “In contrast, an ‘investigative detention’ . . . carries an official
    compulsion to stop and respond . . . . Since this interaction has elements of
    official compulsion it requires reasonable suspicion of unlawful activity.”
    
    DeHart, 745 A.2d at 636
    . In addition, while reasonable suspicion of unlawful
    activity is sufficient to justify a forcible stop, it does not necessarily justify a
    frisk for weapons.     See Commonwealth v. Davis, 
    102 A.3d 996
    , 999
    (Pa.Super. 2014) (“A Terry frisk is a type of investigative detention requiring
    reasonable suspicion that criminal activity is afoot and that the individual
    whose suspicious behavior he is investigating at close range is armed and
    presently dangerous to the officer or to others.”) (internal quotation marks
    omitted, emphasis added).       Only when the officer reasonably believes the
    suspect may be armed and dangerous is a weapons frisk appropriate. See
    Commonwealth v. Pinney, 
    378 A.2d 293
    , 296 (Pa. 1977) (“[I]n the case of
    a self-protective search for weapons, a police officer must be able to point to
    particular facts from which he could reasonably infer that the individual was
    armed and dangerous.”).
    -7-
    J-S81029-16
    Finally, “a custodial detention occurs when the nature, duration and
    conditions of an investigative detention become so coercive as to be,
    practically speaking, the functional equivalent of an arrest.”    
    DeHart, 745 A.2d at 636
    . This level of interaction requires that the police have probable
    cause to believe that the person so detained has committed or is committing
    a crime.    See Commonwealth v. Ellis, 
    662 A.2d 1043
    , 1047 (Pa. 1995)
    (citing Dunaway v. New York, 
    442 U.S. 200
    (1979)).
    The parties agree that Mackey’s seizure was an investigative detention.
    Thus, the central issue is whether Officer O’Shaughnessy possessed the
    necessary “reasonable suspicion” to detain Mackey at the time that detention
    commenced.4
    Preliminarily, however, we must determine at what point Mackey was
    detained.5 See Commonwealth v. Riley, 
    715 A.2d 1131
    , 1135 (Pa.Super.
    1998) (citing Terry, 
    392 U.S. 1
    ) (noting that reasonable suspicion analysis
    examines circumstances when stop began).         Determining that point with
    precision is crucial to the constitutional analysis because the police must have
    reasonable suspicion at the moment of detention; information developed
    ____________________________________________
    4If the officer had reasonable suspicion for the initial detention, he
    would also have had reasonable suspicion to frisk Mackey for weapons, given
    that the tip alleged Mackey possessed a firearm.
    5The trial court’s opinion does not specify the point at which Mackey
    was detained. And while the parties agree that the interaction between Officer
    O’Shaughnessy and Mackey at some point became an investigative detention,
    see Mackey’s Br. at 6; Cmwlth.’s Br. at 6, they do not agree precisely when
    that occurred.
    -8-
    J-S81029-16
    after a police-citizen encounter moves from consensual to coercive cannot be
    used to justify the detention. See Florida v. J.L., 
    529 U.S. 266
    , 271 (2000)
    (“[T]he reasonableness of official suspicion must be measured by what the
    officers knew before they conducted their search.”); Commonwealth v.
    Wiley, 
    858 A.2d 1191
    , 1197 (Pa.Super. 2004).
    An investigative detention “constitutes a seizure of a person and
    activates the protections of the Fourth Amendment.”     Commonwealth v.
    Lewis, 
    636 A.2d 619
    , 622-23 (Pa. 1994). To determine whether and when a
    seizure has occurred, we employ “an objective test entailing a determination
    of whether, in view of all surrounding circumstances, a reasonable person
    would have believed that he was free to leave.”         Commonwealth v.
    Strickler, 
    757 A.2d 884
    , 889 (Pa. 2000) (citations omitted). “In evaluating
    the circumstances, the focus is directed toward whether, by means of physical
    force or show of authority, the citizen-subject’s movement has in some way
    been restrained . . . . In making this determination, courts must apply the
    totality-of-the-circumstances approach, with no single factor dictating the
    ultimate conclusion as to whether a seizure has occurred.” 
    Id. at 890.
    Officer O’Shaughnessy testified that upon entering the bus, he
    immediately identified Mackey based on the radio description and then drew
    his service weapon and pointed it at Mackey while ordering Mackey to show
    -9-
    J-S81029-16
    his hands.6 N.T. at 14-15. At that moment – when the officer pointed his
    weapon at Mackey and ordered him to show his hands – Mackey was
    detained.7 Under these circumstances, a reasonable person would not feel
    ____________________________________________
    6Officer O’Shaughnessy testified on direct examination as to his actions
    after boarding the bus:
    Q:    Officer, what happened when you entered the bus?
    A:    As soon as I got on the bus, going down the aisles –
    the entire bus was full. Towards the back of the bus,
    on the left hand side, right by the back door, I saw
    [Mackey] who, at the time, was wearing a flowered
    hat described in the radio call. The radio call said a
    white T-shirt. [Mackey’s] shirt was white on the back,
    black on the front, similar to the one he’s wearing
    today, if not the same one. As I am walking down the
    aisle, I draw my gun to make sure that he didn’t draw
    his, if he decided to pull it. This is a crowded bus. I
    don’t want anything to happen.
    Q:    Okay. Approximately how much time did it take you
    to reach [Mackey] at the time?
    A:    Seconds.
    Q:    Okay. And what happened when you did come into
    contact with [Mackey]?
    A:    While walking down the aisle, I had my weapon
    pointed at him, told him to show me his hands. He
    placed his hands up. Once I got closer to him, I asked
    him to put his hands behind his back so that I could
    handcuff him for safety of the other passengers.
    N.T. at 14-15.
    7In his brief, Mackey also suggests in passing that he was detained even
    earlier, when Officer O’Shaughnessy stopped the bus on Cecil B. Moore
    Avenue. Mackey Br. at 8. In light of our conclusion that Mackey was detained
    when the officer raised his service weapon and ordered Mackey to show his
    hands, and that the officer lacked reasonable suspicion for that detention, we
    need not consider this undeveloped argument.
    - 10 -
    J-S81029-16
    free to leave or otherwise terminate the encounter. See United States v.
    Mendenhall, 
    446 U.S. 544
    , 554 (1980) (listing “examples of circumstances
    that might indicate a seizure,” including “the display of a weapon by an officer
    . . . or the use of language or tone of voice indicating that compliance with
    the officer’s request might be compelled.”).
    The Commonwealth does not appear to disagree that Mackey was
    detained once the officer ordered him to put his hands in the air. Instead, it
    recasts the scene on the bus as follows:       Officer O’Shaughnessy drew his
    weapon as soon as he boarded the bus, observed that “everyone on the bus
    except for [Mackey] ducked [while Mackey] stared straight at the officer,” and
    then ordered Mackey to raise his hands.          Cmwlth.’s Br. at 8-9.      The
    Commonwealth draws this time line in order to include Mackey’s unique
    response to the drawn service weapon as part of the quantum of evidence
    that it claims gave Officer O’Shaughnessy the reasonable suspicion needed to
    justify what it describes as the subsequent seizure of Mackey. The chief flaw
    in this argument is that the Commonwealth’s description of the sequence of
    events on the bus is not supported by the record. While the Commonwealth
    is entitled to all “reasonable inferences drawn from the facts in light of the
    officer’s experience,” Commonwealth v. Holmes, 
    14 A.3d 89
    , 95 (Pa. 2011),
    its assertion here is supported neither by the suppression hearing testimony
    nor by the trial court’s findings of fact. As both Officer Shaughnessy testified
    and the trial court found, the officer pointed his weapon at Mackey and ordered
    - 11 -
    J-S81029-16
    him to raise his hands as soon as he located Mackey on the bus. Mackey’s
    unique reaction followed, rather than preceded, the seizure.
    Next,   we   must    determine    whether    Officer   O’Shaughnessy     had
    reasonable suspicion to detain Mackey when he drew his service weapon and
    ordered Mackey to show his hands. An officer may stop and briefly detain a
    person for investigatory purposes when that officer has “reasonable suspicion,
    based on specific and articulable facts, that criminal activity may be afoot.”
    Commonwealth v. Allen, 
    725 A.2d 737
    , 740 (Pa. 1999).                         “[T]he
    fundamental inquiry is an objective one, namely, whether the facts available
    to the officer at the moment of the intrusion warrant a man of reasonable
    caution in the belief that the action taken was appropriate.” Commonwealth
    v. Gray, 
    784 A.2d 137
    , 142 (Pa.Super. 2001) (citation omitted). We must
    consider the totality of the circumstances, including such factors as “tips, the
    reliability of the informants, time, location, and suspicious activity.” 
    Id. (citing Commonwealth
    v. Freeman, 
    757 A.2d 903
    , 908 (Pa. 2000)).                   As noted
    above, however, the relevant “totality” of circumstances does not include
    events that occurred after the seizure was effectuated. For this reason, we
    may not consider either Mackey’s reaction to the drawn gun or his “waddling”
    off the bus in an apparent attempt to keep a weapon from slipping down his
    pants. Because both events occurred after the seizure, neither is relevant to
    the reasonable suspicion analysis.
    Where an investigative detention is based on an anonymous tip, “we
    must determine whether under the totality of the circumstances the
    - 12 -
    J-S81029-16
    informant’s tip established the necessary reasonable suspicion that criminal
    activity was afoot.”      Commonwealth v. Martin, 
    705 A.2d 887
    , 892
    (Pa.Super. 1997) (quoting Alabama v. White, 
    496 U.S. 325
    (1990)). The
    veracity and reliability of anonymous tips are particularly difficult for the police
    to evaluate. See 
    White, 496 U.S. at 325
    . Unlike trusted (or at least tested)
    informants or members of the public not concealing their identity, anonymous
    tipsters know they cannot be held to account for false allegations.            See
    Florida v. J.L., 
    529 U.S. 266
    , 270 (2000). In addition, they often fail to
    reveal the basis for their alleged knowledge and are generally unavailable to
    answer follow-up questions from police. See 
    White, 496 U.S. at 329
    (citing
    Illinois v. Gates, 
    462 U.S. 213
    , 237 (1983)).
    The United States Supreme Court has made clear that an anonymous
    tip that a particular person in a particular location is carrying a firearm does
    not, by itself, establish reasonable suspicion for an investigative detention.
    
    J.L., 529 U.S. at 274
    . In J.L., police received an anonymous tip that a “young
    black male standing at a particular bus stop and wearing a plaid shirt was
    carrying a gun.” 
    Id. at 268.
    Two officers responded to the call and, about six
    minutes later, arrived at the bus stop to find three black males. 
    Id. One of
    the males, J.L., was wearing a plaid shirt. 
    Id. “Apart from
    the tip, the officers
    had no reason to suspect any of the three of illegal conduct.”         
    Id. Acting solely
    on the anonymous tip and matching description, officers ordered J.L. to
    “put his hands on the bus stop, frisked him, and seized a gun from J.L.’s
    pocket.” 
    Id. - 13
    -
    J-S81029-16
    Recognizing that “an anonymous tip alone seldom demonstrates the
    informant’s basis of knowledge or veracity,” the J.L. Court analyzed whether
    the tip contained “sufficient indicia of reliability to provide reasonable
    suspicion to make the investigatory stop.” 
    Id. at 270
    (quoting 
    White, 496 U.S. at 327
    , 329).        The Court unanimously held that the officers lacked
    reasonable suspicion based on the anonymous tip:
    The tip in the instant case lacked the moderate indicia of
    reliability present in White[8] and essential to the Court's
    decision in that case. The anonymous call concerning J.L.
    provided no predictive information and therefore left the police
    without means to test the informant’s knowledge or credibility.
    That the allegation about the gun turned out to be correct does
    not suggest that the officers, prior to the frisks, had a
    reasonable basis for suspecting J.L. of engaging in unlawful
    conduct: The reasonableness of official suspicion must be
    measured by what the officers knew before they conducted
    their search. All the police had to go on in this case was the
    bare report of an unknown, unaccountable informant who
    neither explained how he knew about the gun nor supplied any
    basis for believing he had inside information about J.L. If
    White was a close case on the reliability of anonymous tips,
    this one surely falls on the other side of the line.
    
    Id. at 271.
    ____________________________________________
    8In White, the anonymous tipster provided police information about
    the appellant’s appearance, her vehicle, her starting location and destination,
    the time appellant would leave, and the route the appellant would 
    take. 496 U.S. at 327
    , 331. The United States Supreme Court held that, while the facts
    presented a “close case,” the information provided indicia of reliability because
    “only a small number of people are generally privy to a person’s itinerary.”
    
    Id. at 332.
    However, the White Court emphasized that the “reliability of the
    informer’s allegations” was the result of “independent corroboration by the
    police of significant aspects of the informer’s predictions.” 
    Id. - 14

    J-S81029-16
    Three years prior to J.L., the Pennsylvania Supreme Court reached the
    same conclusion announced by the J.L. Court — police lack reasonable
    suspicion where an anonymous tip merely provides a description and the
    location of a person who the tipster claims is armed. See Commonwealth
    v. Jackson, 
    698 A.2d 571
    (Pa. 1997). In Jackson, an officer received a radio
    report “of a man in green jacket carrying a gun” in a specific location.
    
    Jackson, 698 A.2d at 572
    . The officer responded within two minutes, finding
    Jackson, who was wearing a green jacket, amongst a group of people. 
    Id. The officer
    immediately frisked Jackson and did not find a gun, but did find a
    small key box that contained packets of cocaine. 
    Id. The Jackson
    Court concluded that the officer lacked reasonable
    suspicion to stop and frisk Jackson, noting that “[w]hen . . . the underlying
    source of the police department’s information is an anonymous telephone call,
    . . . the tip should be treated with particular suspicion.” 
    Id. at 575.
    The Court
    adopted the following reasoning from its earlier plurality opinion in
    Commonwealth v. Hawkins, 
    692 A.2d 1068
    (Pa. 1997):
    The fact that the subject of the call was alleged to be
    carrying a gun, of course, is merely another allegation, and
    it supplies no reliability where there was none before. And
    since there is no gun exception to the Terry requirement
    for reasonable suspicion of criminal activity, in the typical
    anonymous caller situation, the police will need an
    independent basis to establish the requisite suspicion.
    
    Id. (quoting Hawkins,
    692 A.2d at 1070). Thus, “the police must establish
    that they have a reasonable suspicion that the individual is involved in, or
    about to commit a crime. If the tip contains sufficient information, the police
    - 15 -
    J-S81029-16
    can do this by corroborating sufficient details of the tip. Otherwise, the police
    must investigate further by means not constituting a search and seizure.” 
    Id. Our decision
    today is controlled by the decision of the United States
    Supreme Court in J.L., as well as by our Supreme Court’s decision in Jackson.
    The facts in J.L. and this case are nearly indistinguishable — the only
    difference being that Mackey was traveling on a bus whereas the suspect in
    J.L. was standing at a bus stop.           Like the officers in J.L., Officer
    O’Shaughnessy stopped Mackey within minutes of receiving the radio call,
    based on the matching appearance and location.         Like the officers in J.L.,
    Officer O’Shaughnessy seized his suspect on arrival, without developing any
    support for the tipster’s assertion that the suspect was armed. Further, both
    anonymous tips reported only that the person in question was armed — there
    was no suggestion that either suspect was carrying a firearm without a license
    or was otherwise involved in or about to commit a crime. See 18 Pa.C.S. §§
    6105(a)(1), 6106(a)(1), 6108. Indeed, in neither case did the officers on the
    scene observe any signs of distress from others in the vicinity. In sum, in this
    case as in J.L., “[a]ll the police had to go on . . . was the bare report of an
    unknown, unaccountable informant who neither explained how he knew about
    the gun nor supplied any basis for believing he had inside information about
    [the suspect.]” 
    J.L., 529 U.S. at 271
    . Absent any independent information
    to corroborate the anonymous tip, we conclude that Officer O’Shaughnessy
    lacked reasonable suspicion to seize Mackey and, therefore, the gun recovered
    should have been suppressed as the fruit of an illegal seizure.
    - 16 -
    J-S81029-16
    In its opinion, the trial court relied heavily on the officer’s confirmation
    of Mackey’s precise location and distinctive flowered hat as corroboration for
    the anonymous tip. 1925(a) Op. at 6. This conclusion, however, is directly
    contrary to the decision in J.L. Like the tip in J.L., the anonymous tip here
    only described Mackey’s appearance and current location — it provided no
    predictions of future behavior of any kind that police officers could have
    corroborated through observation, let alone any allegations of future criminal
    activity. See 
    White, 496 U.S. at 332
    (noting that a “caller’s ability to predict
    . . . future behavior . . . demonstrate[s] inside information [and] a special
    familiarity with [appellant’s] affairs . . . . [I]t is reasonable for police to believe
    that a person with access to such information is likely to also have access to
    reliable information about that individual’s illegal activities.”) (emphasis in
    original). As in J.L., the information provided did not include any indicia of
    reliability in the tip — the only details police could corroborate were Mackey’s
    location and his appearance. See 
    J.L., 529 U.S. at 271
    ; see also 
    Jackson, 698 A.2d at 574
    (“[T]he only detail that the police were able to corroborate in
    this case was the fact that appellant was at the location described, and that
    he was wearing a green jacket.”).         Officer O’Shaughnessy could not have
    known “whether the information [from the radio call] was reliable . . . . [or
    merely] a prank call.” 
    Hawkins, 692 A.2d at 1070
    . Thus, in order to lawfully
    seize Mackey, Officer O’Shaughnessy needed to corroborate the anonymous
    tip through further observation.
    - 17 -
    J-S81029-16
    Despite the lack of independent corroboration, the trial court concluded
    that the totality of the circumstances provided Officer O’Shaughnessy with
    reasonable suspicion that Mackey was armed. 1925(a) Op. at 6. The court
    found reasonable suspicion based on the combination of the anonymous tip,
    Mackey’s “unusual” behavior, his “waddling” off the bus, and his travel
    through a high-crime area.9 
    Id. We disagree.
    As noted above, the relevant inquiry is whether an officer possesses
    reasonable suspicion of criminal activity before initiating the detention. 
    J.L., 529 U.S. at 271
    ; 
    Riley, 715 A.2d at 1135
    . While experience teaches that the
    reality of these encounters often does not yield sharp constitutional lines, the
    prescribed constitutional analysis demands that at the moment an encounter
    moves from a consensual “mere encounter” to an investigative detention,
    police must already have the requisite reasonable suspicion to support that
    detention – reasonable suspicion cannot be based on information discovered
    after the detention has begun. 
    J.L., 529 U.S. at 271
    ; see also 
    Wiley, 858 A.2d at 1197
    (holding that anonymous tipster’s post-detention revelation of
    ____________________________________________
    9   In its opinion, the trial court noted that:
    Officer O’Shaughnessy testified that in his seven years’
    experience as a police officer, he had made many arrests
    for violent crimes, including 25 for guns, and that 75 percent
    of arrests made in the area of 20th and Cecil B. Moore were
    for crimes of violence, and thus it is known as a high violent
    crime area. (See N.T. 02/09/15, pp. 7-9).
    1925(a) Op. at 2 n.1.
    - 18 -
    J-S81029-16
    identity to police could not be considered in reasonable suspicion analysis). A
    trial court must identify this moment to frame its analysis of the
    constitutionality of police conduct. Here, the officer’s observations after the
    detention began, such as Mackey’s behavior in response to having a weapon
    pointed at him10 and his “waddling” when exiting the bus, cannot establish
    that reasonable suspicion existed at the earlier moment of seizure. Officer
    O’Shaughnessy needed reasonable suspicion that Mackey was committing a
    crime before initiating the detention, which the anonymous tip alone failed to
    provide.11
    ____________________________________________
    In its brief, the Commonwealth relies heavily on the fact that Mackey
    10
    responded differently than did the other passengers when Officer
    O’Shaughnessy drew his weapon. See Cmwlth.’s Br. at 8-9. However, as
    discussed above, we cannot consider Mackey’s reaction in the reasonable
    suspicion analysis because that occurred after the detention began – Mackey
    was clearly seized at the moment Officer O’Shaughnessy pointed his weapon
    at Mackey. Cf. In re D.M., 
    781 A.2d 1161
    , 1164 (holding that requisite cause
    is measured “at the time [police] initially approach[] the [suspect]” and
    suspect’s flight after seizure cannot be used in reasonable suspicion calculus).
    Indeed, Mackey’s distinctive reaction might well have been based on the fact
    he, and not the other passengers, was being seized by the police.
    11It bears noting, as the United States Supreme Court did in J.L., that
    the fact “[t]hat the allegation about the gun turned out to be correct does not
    suggest that the officer[], prior to the frisk[], had a reasonable basis for
    suspecting [the subject] of engaging in unlawful conduct.” 
    J.L., 529 U.S. at 271
    . Courts reviewing motions to suppress must guard against the hindsight
    bias occasioned by the fact that in each such case, the police turned out to be
    right – the suspect did indeed possess the item (or other evidence of crime)
    for which the police were searching. The set of circumstances for which our
    constitutional protections may be more easily understood as valuable – when
    the police turn out to be wrong in their suspicion that a particular person is
    engaged in wrongdoing – most often do not result in litigation.
    - 19 -
    J-S81029-16
    Further, while we recognize that a combination of facts may establish
    reasonable suspicion, see Commonwealth v. Cook, 
    735 A.2d 673
    , 677 (Pa.
    1999) (citing Terry v. Ohio, 
    392 U.S. 1
    , 22 (1968)), and a suspect’s location
    in a high-crime area may be a factor supporting an officer’s reasonable
    suspicion that criminal activity is afoot, Mackey’s travel through a high-crime
    area on a bus does not change our analysis. This fact did not corroborate the
    information in the anonymous tip and provided no information from which
    Officer O’Shaughnessy could determine whether Mackey was carrying a
    firearm, was committing a crime, or was about to commit a crime.           See
    Commonwealth v. Ayala, 
    791 A.2d 1202
    , 1210 (Pa.Super. 2002) (“Our
    caselaw is quite emphatic that an individual’s mere presence in a high crime
    area is manifestly insufficient to justify a Terry stop.”).
    The Commonwealth’s final argument in support of affirmance centers on
    an understandable concern for public safety. In particular, the Commonwealth
    argues that Officer O’Shaughnessy’s actions were reasonable; it attempts to
    distinguish J.L. by citing safety concerns, noting that officers had a “report
    [that] described a man with a gun on a crowded public bus, an enclosed area
    where every passenger was at risk.” Cmwlth.’s Br. at 9. While these public
    safety concerns are palpable, we disagree that they render the officer’s actions
    constitutional, as the United States Supreme Court rejected similar arguments
    in J.L.
    There, the State of Florida, and the United States as amicus curiae,
    advanced two related arguments. First, they argued that the Court should
    - 20 -
    J-S81029-16
    create a per se rule finding reasonable suspicion where “(1) an anonymous tip
    provides a description of a particular person at a particular location illegally
    carrying a concealed firearm, (2) police promptly verify the pertinent details
    of the tip except the existence of the firearm, and (3) there are no factors that
    cast doubt on the reliability of the tip.” 
    J.L., 529 U.S. at 271
    . Second, they
    argued that even where a tip is later to found to lack sufficient indicia of
    reliability, the Court should recognize a public-safety-based “firearm
    exception” to Terry and categorically allow a stop and frisk where a tip alleges
    that a person is carrying an illegal firearm. 
    Id. at 272.
    The J.L. Court rejected both of these arguments. With respect to the
    per se rule, the Court concluded that an anonymous tip, in the context of
    reasonable suspicion, requires not only an accurate description that allows for
    identification but also information that shows “the tipster has knowledge of
    concealed criminal activity.” 
    Id. In response
    to the request that it recognize
    some form of “firearm exception” to Terry, the Court declined, reasoning as
    follows:
    Firearms are dangerous, and extraordinary dangers
    sometimes justify unusual precautions.       Our decisions
    recognize the serious threat that armed criminals pose to
    public safety; Terry’s rule, which permits protective police
    searches on the basis of reasonable suspicion rather than
    demanding that officers meet the higher standard of
    probable cause, responds to this very concern. But an
    automatic firearm exception to our established
    reliability analysis would rove too far.          Such an
    exception would enable any person seeking to harass
    another to set in motion an intrusive, embarrassing
    police search of the targeted person simply by placing
    - 21 -
    J-S81029-16
    an anonymous call falsely reporting the target's
    unlawful carriage of a gun. Nor could one securely
    confine such an exception to allegations involving firearms.
    Several Courts of Appeals have held it per se foreseeable for
    people carrying significant amounts of illegal drugs to be
    carrying guns as well. If police officers may properly
    conduct Terry frisks on the basis of bare-boned tips about
    guns, it would be reasonable to maintain under the above-
    cited decisions that the police should similarly have
    discretion to frisk based on bare-boned tips about narcotics.
    As we clarified when we made indicia of reliability critical in
    Adams and White, the Fourth Amendment is not so easily
    satisfied.
    
    Id. at 272-273
    (internal citations omitted, emphasis added); see also
    
    Jackson, 698 A.2d at 575
    (declining to create a “firearms exception” to Terry
    under Pennsylvania law because the Pennsylvania Supreme Court “is not
    empowered . . . to overrule Terry in favor of a lower standard of protection
    under the state and federal constitutions”).12
    ____________________________________________
    12The dissent does not mention, let alone attempt to distinguish, the
    Supreme Court’s decision in J.L. Instead, it castigates the opinion announcing
    the judgment in Commonwealth v. Hawkins, 
    692 A.2d 1068
    (Pa. 1997) for
    failing to take seriously “the Commonwealth’s references to schoolyard
    shootings and assassination of public figures as possible consequences if
    Terry jurisprudence always required independent corroboration of ‘man with
    gun’ anonymous tips,” Dissenting Op. at 1-2. Whatever the relevance of dicta
    in a non-binding opinion to the future development of the law in this area, this
    Court remains bound by the decisions of the United States Supreme Court.
    - 22 -
    J-S81029-16
    While the J.L. Court rejected a categorical “firearms exception,” the
    Court did not foreclose the possibility that certain types of public-safety
    concerns13 could excuse the reliability requirement:
    The facts of this case do not require us to speculate about
    the circumstances under which the danger alleged in an
    anonymous tip might be so great as to justify a search even
    without a showing of reliability. We do not say, for example,
    that a report of a person carrying a bomb need bear the
    indicia of reliability we demand for a report of a
    person carrying a firearm before the police can
    constitutionally conduct a frisk.
    
    J.L., 529 U.S. at 273-74
    (emphasis added); see also City of Indianapolis
    v. Edmond, 
    531 U.S. 32
    , 44 (2000) (noting that, with respect to
    “circumstances that may justify a law enforcement checkpoint . . . the Fourth
    Amendment would almost certainly permit an appropriately tailored roadblock
    set up to thwart an imminent terrorist attack”). While the Commonwealth
    correctly points out that the confined space of a bus presented the officer in
    this case with a somewhat different and potentially more acute set of safety
    ____________________________________________
    13 The trial court’s decision was based in part on its belief that Officer
    O’Shaughnessy’s decision to order Mackey off the bus was the officer’s only
    reasonable alternative in light of the risk to public safety. 1925(a) Op. at 6
    (“Given the tight, crowded quarters and obvious concern for public safety, the
    officer reasonably removed [Mackey] from the bus.”). We acknowledge that
    the result in this case, compelled by controlling authority from both the United
    States Supreme Court and our Supreme Court, begs an important question:
    What should a police officer do when confronted with the sort of anonymous
    tip at issue here? The answer, also compelled by controlling authority, is to
    conduct the additional investigation necessary to corroborate (or discount) the
    tip’s allegation. See 
    Jackson, 698 A.2d at 575
    (“police must investigate
    further by means not constituting a search and seizure”).

    J-S81029-16
    concerns than did the bus stop in J.L., that difference appears to be one of
    degree rather than kind.14 In any event, we decline to create an exception to
    the well-established reliability requirement on these facts.15

    ____________________________________________
    14 Here, as in J.L., the anonymous caller did not report that Mackey had
    brandished the weapon, threatened its use, or even told another person that
    he was carrying a concealed firearm. As the concurring opinion notes, and
    “[a]s illustrated by the petition for allowance of appeal in [Commonwealth
    v.] Hicks, [
    2017 WL 4351309

    appeal)], the dangers posed by the mere presence of a firearm with respect
    to Fourth Amendment analysis is a matter of dispute.” Conc. Op. at 7.
    Nonetheless, given the close factual similarity of this case to J.L., and the fact
    that the J.L. Court rejected public safety arguments almost identical to those
    presented here, we are constrained to reverse. See also

    we have already determined that Officer O’Shaughnessy did not have
    reasonable suspicion to seize Mackey, we need not address this issue.
