    A pretrial motion to suppress evidence was heard by Michael
    D. Ricciuti, J.
    An application for leave to prosecute an interlocutory
    appeal was allowed by Lenk, J., in the Supreme Judicial Court
    for the county of Suffolk, and the appeal was reported by her to
    the Appeals Court. The Supreme Judicial Court on its own
    initiative transferred the case from the Appeals Court.
    K. Hayne Barnwell (Janice Bassil also present) for the
    defendant.

    GAZIANO, J.   Thirteen minutes after a shooting, and one
    half-mile away, two police officers encountered the defendant
    walking on the sidewalk.    They drove slowly alongside him for
    approximately one hundred yards, while he repeatedly rebuffed
    their attempts to speak with him.    When one of the officers
    started to get out of the cruiser, the defendant sprinted away.
    The officers gave chase, stopped the defendant, and arrested
    him.   They found a firearm lying on the ground along the route
    on which he had run.    The defendant subsequently was indicted on
    charges including murder in the first degree.
    In a motion to suppress, the defendant argued that the
    officers stopped him without reasonable suspicion at the moment
    that one of the officers opened the door of the cruiser, and
    that all of the evidence subsequently obtained as a result of
    the stop must be suppressed.    The defendant, who is Black, was
    seventeen years at the time of the stop.    He argued, as he does
    before this court, that his race and age should form part of the
    3
    totality of the circumstances relevant to a determination of
    when he was seized.    The defendant contends that juveniles are
    more susceptible to police coercion, and therefore will be
    seized in circumstances where adults would not.    He also
    maintains that, based on the history and present reality of
    policing and race, police communications directed at African-
    Americans will have greater coercive power than those directed
    at people of other races.
    After his motion to suppress was denied, the defendant
    sought leave in the county court to pursue an interlocutory
    appeal.    His petition was allowed, and his appeal was ordered to
    proceed in the Appeals Court; we then transferred the matter to
    this court on our own motion.
    We conclude that the defendant indeed was seized when,
    after having trailed him for one hundred yards in a police
    cruiser and repeatedly having tried to converse with him, the
    officer in the front passenger's seat opened the door of the
    cruiser.   On the record here, however, the judge did not abuse
    his discretion in relying on the officers' testimony about their
    experience with firearms, and in concluding that, in the
    circumstances, they had a reasonable, articulable suspicion of
    criminal activity.    Accordingly, we affirm the denial of the
    motion to suppress.    Going forward, however, the age of a
    juvenile suspect, if known to the officer or if objectively
    4
    apparent to a reasonable officer, will be part of the totality
    of the circumstances relevant to whether the juvenile was seized
    under art. 14 of the Massachusetts Declaration of Rights.
    With respect to the defendant's arguments on race, we have
    examined the continued relevance of our reasoning in
    Commonwealth v. Warren, 
    475 Mass. 530
    , 540 (2016), on the
    question of reasonable suspicion.   In that case, we concluded
    that an innocent African-American man in an urban area might
    flee from police for fear of racial profiling, and therefore the
    weight of the inference properly given to flight should be less
    when the individual is African-American.   See 
    id.
        We conclude
    that this reasoning remains pertinent to the reasonable
    suspicion analysis, and should be extended to other types of
    nervous or evasive behavior in addition to flight.2
    Background.   We summarize the facts as found by the motion
    judge.   See Commonwealth v. Phifer, 
    463 Mass. 790
    , 791 (2012).

    the motion to suppress.   At the time of the hearing, Officer

    Joseph Abasciano had been a Boston police officer for eleven
    years, with gaps in service of several years due to military
    deployment and an injury.   He had been trained regarding the use
    of firearms and the identification of concealed firearms by the
    Boston police department and the United States Marine Corps.
    Prior to the night of the shooting, he had participated in
    multiple arrests of suspects in possession of firearms.3
    At the time of the hearing, Officer Brian Garney had been
    an officer for three years.   He had been working patrol for
    about several months before the night of the shooting.     At that
    point, he had never made an arrest, but had assisted with a few.
    He had been trained to identify concealed firearms, in part
    through a presentation at the police academy entitled
    "Characteristic of Armed Gunman Overview."
    On the evening of January 9, 2017, Abasciano and Garney
    were on patrol in their marked cruiser; Abasciano was driving.
    At about 7:27 P.M., they received a notification from
    "ShotSpotter," a system that identifies firearm discharges by
    3 The defendant argues that the judge's finding concerning
    the number of arrests was clearly erroneous. He notes that, in
    response to a court order directing the Boston police department
    to produce all firearm-related incident reports involving
    Officer Joseph Abasciano from 2007 to 2011, the department
    produced only two reports. Nonetheless, the judge's finding
    that Abasciano had made at least ten arrests was supported by
    Abasciano's testimony, and therefore was not clearly erroneous.

    480 Mass. 645
    , 655 n.7 (2018).

    sound and directs officers to the general location of the shots.
    The notification indicated that shots had been fired near
    Dearborn Street in the Roxbury section of Boston.
    The officers also received a radio report that a person had
    been shot and was severely injured, and that three people had
    run from the area.   No descriptions of the suspects were given.
    Unbeknownst to the officers, the victim died shortly thereafter.
    The report indicated that the men had run towards Adams Street,
    heading southeast on Eustis Street.   The officers, however,
    mistakenly believed that the report stated that the suspects had
    run away from Adams Street.   Accordingly, the officers headed to
    the northwest of the location of the shooting.   Abasciano was
    aware that there had been a rivalry between gangs based near
    that location, and that one gang was based in the area to which
    they were driving.   Garney testified that they drove in that
    direction because of ongoing, gang-related violence in the area.
    The evening was cold, and the officers did not see any
    pedestrians.   When they reached the corner of Melnea Cass
    Boulevard and Shawmut Avenue, thirteen minutes after the
    shooting, they saw the defendant walking on Dewitt Drive, one
    street away.   He was approximately one-half mile from the
    reported location of the shooting.
    The officers drove up to the defendant and saw that he
    appeared to be holding an object in his right jacket pocket that
    7
    was consistent with the size of a firearm.     The officers could
    see immediately that the defendant was African-American and was
    younger than twenty-one years old.    Abasciano called out, "Hey,
    man, can I holler at you?"    The defendant increased his pace and
    responded, "For what?"    Abasciano said that something had
    happened in the area, and he wanted to know if the defendant had
    seen or heard anything.    The officers could not hear the
    defendant's response, which Abasciano described as a mumble.
    They drove slowly alongside the defendant for approximately one
    hundred yards as he walked on the sidewalk.     Throughout the
    exchange, the defendant did not make eye contact with the
    officers.    At one point, he turned the right side of his body
    away from them, thereby blocking them from being able to see his
    right jacket pocket.     To Abasciano the movement appeared
    unnatural.    The defendant began looking around in various
    directions.
    Garney got out of the cruiser, and the defendant began to
    run away.    The officers gave chase; Garney was on foot and
    Abasciano remained in the cruiser.     During the pursuit, the
    officers noticed the defendant running awkwardly with his hands
    in his pockets.    Abasciano got out of the cruiser and saw the
    defendant starting to take an object out of his right pocket.
    Abasciano drew his weapon and ordered the defendant to stop, and
    the defendant stopped shortly thereafter.     The officers
    8
    recovered a firearm on the sidewalk where the defendant had been
    running.
    Dr. Dawn Sweet, a professor at a large university,
    testified for the defense.     Among other testimony, she described
    a recent study she had conducted, which was introduced in
    evidence, on visual detection of concealed weapons.     See Sweet,
    Meissner, & Atkinson, Assessing Law Enforcement Performance in
    Behavior-Based Threat Detection Tasks Involving a Concealed
    Weapon or Device, 41 Law and Human Behavior 411 (2017) (threat
    study).     In the threat study, participants, some of whom were
    carrying concealed firearms, were videotaped as they walked into
    a secure facility.     Fifty-one police officers and fifty-six
    college students watched the recordings and attempted to
    identify which subjects were carrying firearms.     Ultimately, the
    police officers performed no better than did the college
    students.    Officers with more years of experience were more
    likely than those with fewer to identify someone as carrying a
    concealed firearm where no weapon was present.
    Sweet also testified that studies have shown that police
    officers are more likely to view African-Americans as threats,
    something she described as implicit bias.     She explained that
    police interactions could be affected by stereotype threat, a
    phenomenon in which a member of a particular group exhibits
    certain behaviors out of concern that he or she will be
    9
    stereotyped negatively based on membership in that group.      Sweet
    explained that stereotype threat could cause an African-American
    teenager to experience anxiety.    In response to a hypothetical
    question based on the facts known to the officers before they
    began the chase, Sweet said that there was no scientific
    literature that would support the conclusion that the defendant
    had been carrying a firearm.    The defendant also introduced an
    additional six studies regarding implicit racial bias and
    stereotype threat.
    The judge credited the officers' testimony, and discounted
    Sweet's testimony and the results reported in the six other
    studies.    The judge concluded that the officers seized the
    defendant near the end of the chase, when Abasciano pointed his
    weapon and ordered the defendant to stop; the judge determined
    that the stop had been supported by reasonable suspicion.
    Discussion.      When reviewing a ruling on a motion to
    suppress, we accept the motion judge's findings of fact absent
    clear error.   See Commonwealth v. Franklin, 
    456 Mass. 818
    , 820
    (2010).    In addition, the motion judge, who heard and saw the
    witnesses, determines the weight and credibility of the
    evidence.   See Commonwealth v. Gomes, 
    453 Mass. 506
    , 509 (2009).
    With respect to legal questions, however, we "conduct an
    independent review of [the] ultimate findings and conclusions of
    10
    law."   Commonwealth v. Jones-Pannell, 
    472 Mass. 429
    , 431 (2015),
    quoting Commonwealth v. Ramos, 
    470 Mass. 740
    , 742 (2015).
    1.   Seizure.   The defendant argues that he was seized when
    the officer opened the door of the cruiser, that his age and
    race are two of the objective circumstances that should have
    been considered in the seizure analysis, and that the judge
    erred by not taking them into account.
    Under the Fourth Amendment to the United States
    Constitution, a person is seized "only if, in view of all of the
    circumstances surrounding the incident, a reasonable person
    would have believed that he [or she] was not free to leave."
    Michigan v. Chesternut, 
    486 U.S. 567
    , 573 (1988), quoting United
    States v. Mendenhall, 
    446 U.S. 544
    , 554 (1980) (opinion of
    Stewart, J.).   See California v. Hodari D., 
    499 U.S. 621
    , 626
    (1991) (seizure occurs only where officer applies physical force
    or suspect submits to show of authority).   Under art. 14, a
    seizure occurs when an officer, "through words or conduct,
    objectively communicate[s] that the officer would use his or her
    police power to coerce [an individual] to stay."   Commonwealth
    v. Matta, 
    483 Mass. 357
    , 362 (2019), citing Commonwealth v.
    Barros, 
    435 Mass. 171
    , 175-176 (2001).   We interpret the
    officer's actions based on the totality of the circumstances
    surrounding the encounter.   See Matta, supra.
    11
    To decide whether there was error in the judge's decision
    to deny the motion to suppress, we first must determine the
    moment of seizure.     See Commonwealth v. Narcisse, 
    457 Mass. 1
    , 5
    (2010).   "[Article] 14 provides more substantive protection than
    does the Fourth Amendment in defining the moment" of seizure.
    Commonwealth v. Lyles, 
    453 Mass. 811
    , 812 n.1 (2009), citing
    Commonwealth v. Stoute, 
    422 Mass. 782
    , 786-789 (1996).
    Accordingly, we analyze the seizure under "the more stringent
    standards of art. 14 with the understanding that, if these
    standards are satisfied, then so too are those of the Fourth
    Amendment."   See Lyles, supra, citing Commonwealth v. Williams,
    
    422 Mass. 111
    , 115 n.9 (1996).
    a.    Age.    In J.D.B. v. North Carolina, 
    564 U.S. 261
    , 271-
    276 (2011), the United States Supreme Court addressed whether
    age is relevant to the custody inquiry under Miranda v. Arizona,
    
    384 U.S. 436
    , 444 (1966) (requiring warnings prior to custodial
    interrogation).    Custody exists when "a reasonable person in the
    suspect's shoes would experience the environment in which the
    interrogation took place as coercive."     Commonwealth v. Larkin,
    
    429 Mass. 426
    , 432 (1999).    See Commonwealth v. Sneed, 
    440 Mass. 216
    , 220 (2003) (setting forth certain "indicia of custody").
    The Court in J.D.B., supra, was forced to reconcile two
    potentially conflicting considerations.    On the one hand, the
    Court recognized the evident fact that "[i]n some circumstances,
    12
    a child's age would have affected how a reasonable person in the
    suspect's position would perceive his or her freedom to leave"
    (quotations and citation omitted).     Id. at 271-272.   But, on the
    other hand, the Court was wary of undermining the objectivity of
    the inquiry, which "avoids burdening police with the task of
    anticipating the idiosyncrasies of every individual
    suspect . . . ."     See id. at 271, citing Berkemer v. McCarty,
    
    468 U.S. 420
    , 430-431 (1984).
    Ultimately, the Court determined that the effects of youth
    on cognition are not entirely individualistic.    See J.D.B., 
    564 U.S. at 272
    .   See also Miller v. Alabama, 
    567 U.S. 460
    , 472-473
    (2012); Commonwealth v. A Juvenile, 
    389 Mass. 128
    , 131-132
    (1983).   Rather, age is "a fact that 'generates commonsense
    conclusions about behavior and perception.'"     J.D.B., supra,
    quoting Yarborough v. Alvarado, 
    541 U.S. 652
    , 674 (2004)
    (Breyer, J., dissenting).     Because those conclusions are widely
    and easily understood, "so long as the child's age was known to
    the officer at the time of police questioning, or would have
    been objectively apparent to a reasonable officer, its inclusion
    in the custody analysis is consistent with the objective nature
    of that test."     See J.D.B., supra at 277.
    The defendant argues that the Court's reasoning in J.D.B.,
    
    564 U.S. at 271-272
    , applies equally to the seizure analysis.
    See 4 W.R. LaFave, Search and Seizure § 9.4(a) (5th ed. 2012 &
    13
    Supp. 2020) (predicting application of reasoning in J.D.B.,
    supra, to seizure).     See also United States v. Ricardo D., 
    912 F.2d 337
    , 342 & n.2 (9th Cir. 1990), citing Dunaway v. New York,
    
    442 U.S. 200
    , 215 & n.17 (1979) ("Over a decade ago, the Supreme
    Court suggested that a suspect's age may be considered in
    determining whether a seizure constitutes an arrest"); In re
    J.G., 
    228 Cal. App. 4th 402
    , 410-411 (2014) ("extending the
    holding [of J.D.B., supra,] to search and seizure cases would
    not be much of a stretch").
    The custody and seizure inquiries, however, are not
    identical.     First, the custody inquiry under Miranda primarily
    protects the right against self-incrimination and the right to
    counsel under the Fifth and Sixth Amendments to the United
    States Constitution and art. 12 of the Massachusetts Declaration
    of Rights.     See Commonwealth v. Martin, 
    444 Mass. 213
    , 214-215
    (2005), citing Commonwealth v. Snyder, 
    413 Mass. 521
    , 531
    (1992).   The seizure inquiry, by contrast, protects the right to
    be free from unreasonable seizures under the Fourth Amendment
    and art. 14.    See Gomes, 453 Mass. at 509-510.   To safeguard
    these distinct rights, the inquiries consider somewhat different
    questions.   Compare Commonwealth v. Groome, 
    435 Mass. 201
    , 211
    (2001) (custody is established "if the defendant reasonably
    believed that he [or she] was not free to leave" [citation
    omitted]) with Matta, 483 Mass. at 362 (seizure occurs when
    14
    officer "objectively communicate[s] that the officer would
    use . . . police power to coerce [a suspect] to stay").
    Despite their differences, the two inquiries also are much
    the same.     At their cores, both inquiries attempt to ascertain
    whether, considering the totality of the circumstances, an
    individual has been compelled to interact with the police.      See
    Matta, 483 Mass. at 362; Groome, 435 Mass. at 211.     Under both
    doctrines, the scope of review is limited to the objective
    circumstances of the encounter.     See Matta, supra (test to
    determine whether someone is seized "is whether an officer has,
    through words or conduct, objectively communicated that the
    officer would use his or her police power to coerce th[e] person
    to stay"); Commonwealth v. Morse, 
    427 Mass. 117
    , 124 (1998),
    quoting Stansbury v. California, 
    511 U.S. 318
    , 323 (1994)
    ("determination of custody depends on the objective
    circumstances of the interrogation, not on the subjective views
    harbored by either the interrogating officers or the person
    being questioned").
    In each context, the naiveté, immaturity, and vulnerability
    of a child will imbue the objective communications of a police
    officer with greater coercive power.     See J.D.B., 
    564 U.S. at 271-272
    .    Pretending otherwise would diminish a juvenile's
    right to be free from unwanted police interactions.     See Barros,
    435 Mass. at 178.     The consideration of age will not undermine
    15
    the objective nature of the inquiry, because many of the effects
    of youth "apply broadly to children as a class" and "are self-
    evident to anyone who was [once] a child . . . ."   J.D.B., 
    564 U.S. at 272
    .   We therefore conclude that a child's age, when
    known to the officer or objectively apparent to a reasonable
    officer, is relevant to the question of seizure under art. 14.
    The question will be whether the officer objectively
    communicated to a person of the juvenile's apparent age that the
    officer would use his or her police power to coerce the juvenile
    to stay.4
    Of course, the exact contours of this inquiry are not yet
    known.   As in any part of our art. 14 jurisprudence, a new rule
    4 Numerous courts in other jurisdictions similarly have held
    that the age of a juvenile suspect should be considered in the
    objective seizure determination. See, e.g., Halley v. Huckaby,
    
    902 F.3d 1136
    , 1145 (10th Cir. 2018), cert. denied, 
    139 S. Ct. 1347
     (2019); In re Appeal in Maricopa County, 
    186 Ariz. 213
    , 217
    (1996); Hunt ex rel. DeSombre v. State, Dep't of Safety &
    Homeland Sec., Div. of Del. State Police, 
    69 A.3d 360
    , 366 (Del.
    2013); J.N. v. State, 
    778 So. 2d 440
    , 442 (Fla. Dist. Ct. App.
    2001); People v. Lopez, 
    229 Ill. 2d 322
    , 353 (2008); In re
    I.R.T., 
    184 N.C. App. 579
    , 584 (2007). Other courts have
    concluded that the age of a juvenile may be relevant to the
    seizure inquiry. See, e.g., Doe v. Heck, 
    327 F.3d 492
    , 510 (7th
    Cir. 2003), as amended on denial of reh'g (May 15, 2003); United
    States v. Ricardo D., 
    912 F.2d 337
    , 342 & n.2 (9th Cir. 1990),
    citing Dunaway v. New York, 
    442 U.S. 200
    , 215 & n.17 (1979);
    Phillips v. County of Orange, 
    894 F. Supp. 2d 345
    , 363 (S.D.N.Y.
    2012). Other courts have noted that characteristics such as
    youth should be included in the seizure analysis only where they
    would be known or apparent to the officer, but have not decided
    whether youth or any other of these characteristics should be
    included in the seizure analysis. See, e.g., In re J.M., 
    619 A.2d 497
    , 501 n.5 (D.C. App. 1992).
    16
    inevitably invites questions of application that cannot be
    answered in the first instance.     See Commonwealth v. Eddington,
    
    459 Mass. 102
    , 109 n.12 (2011) ("touchstone of
    reasonableness . . . necessitates a case-by-case analysis").
    Here, there is insufficient evidence that the officers knew
    or should have known, prior to his arrest, that the defendant
    was below the age of eighteen.     The defendant was seventeen
    years old and six feet tall.     He was wearing a hat and jacket,
    and the area was dark.     The police report stated that the
    officers did not ask the defendant if he had a license to carry
    a firearm because they could tell after approaching him that he
    was under twenty-one years of age.     But that alone is
    insufficient to trigger an inference that the officers should
    have known that he was under the age of eighteen.     Therefore, we
    do not consider his age in our analysis.
    b.   Race.   The defendant also argues that the fact that he
    is African-American should inform our seizure analysis.        In
    Warren, 475 Mass. at 539, we discussed a report from the Boston
    police department indicating that African-American men were
    targeted disproportionately for stops, frisks, and searches in
    the years 2007 to 2010.5    The Boston police department
    5 See Commonwealth v. Warren, 475 Mass. at 539, discussing
    Boston Police Department, Boston Police Commissioner Announces
    Field Interrogation and Observation Study Results,
    17
    subsequently has released two similar reports.6   Although the
    total number of field interrogation and observation (FIO)
    encounters has fallen, African-Americans continue to be targeted
    disproportionately in such encounters.7
    In Warren, 475 Mass. at 539, we examined FIO data in the
    context of reasonable suspicion, as we do in this case, infra.
    The defendant argues that these reports also are relevant to the
    seizure analysis.   He contends that the documented pattern of

    [https://perma.cc/H9RJ-RHNB].
    6 One report analyzed field interrogation and observation
    (FIO) encounters from 2011 to April 2015. See Boston Police
    Department, Boston Police Department Releases Latest Field

    [https://perma.cc/6Z79-VRKM] (2017 Report). The other report
    analyzed information from June 2015 through June 2016. See

    to Increase Transparency and Accountability of Policing

    transparency-and-accountability-of-policing-activities-to-the-
    public [https://perma.cc/4RDS-EWTH] (2016 Report).
    7 In the earlier data, 63.3 percent of FIO subjects were
    African-American. See Warren, 475 Mass. at 539 n.15. From 2011
    to April 2015, 58.5 per cent were African-American. See 2016
    Report. From June 2015 through 2016, 63.6 per cent were
    African-American. See 2017 Report. In the most recent report,
    the Boston police department separated race and ethnicity, which
    previously had been combined in the same category, into
    different categories. See 2017 Report. In order to make
    appropriate comparisons with the report cited in Warren, supra,
    we reference the statistics given for the earlier classification
    scheme that combined race and ethnicity in one category.
    18
    disproportionate FIO stops of African-Americans by Boston police
    injects an element of coercion into police encounters with
    African-American individuals that is not present in other police
    interactions.
    We agree that the troubling past and present of policing
    and race are likely to inform how African-Americans and members
    of other racial minorities interpret police encounters.    See
    generally Commonwealth v. Buckley, 
    478 Mass. 861
    , 871 (2018)
    (noting "enormity . . . of the problem of racial profiling");
    Commonwealth v. Lora, 
    451 Mass. 425
    , 444-445 (2008), quoting
    Commonwealth v. Feyenord, 
    445 Mass. 72
    , 88 (2005), cert. denied,
    
    546 U.S. 1187
     (2006) (Greaney, J., concurring) (discussing
    "humiliating, painful, and unlawful" nature of some police
    encounters with African-American and Hispanic individuals);
    Commonwealth v. Gonsalves, 
    429 Mass. 658
    , 670 (1999) (Ireland,
    J., concurring) (recognizing "widespread public concerns" about
    racial profiling by police).   African-Americans, particularly
    males, may believe that they have been seized in situations
    where other members of society would not.   See Maclin, "Black
    and Blue Encounters" -- Some Preliminary Thoughts About Fourth
    Amendment Seizures:   Should Race Matter?, 
    26 Val. U. L. Rev. 243
    , 255 (1991) ("Black males learn at an early age that
    confrontations with the police should be avoided; [B]lack
    19
    teenagers are advised never to challenge a police officer, even
    when the officer is wrong").
    Notwithstanding these serious concerns, in determining
    whether an individual had been seized, the analysis "must arise
    from the actions of the police officer[,]" and not from the
    individual's state of mind.      See Matta, 483 Mass. at 363.   See
    also Chesternut, 
    486 U.S. at 574
     ("'reasonable person'
    standard   . . . ensures that the scope of Fourth Amendment
    protection does not vary with the state of mind of the
    particular individual").    We maintain an objective standard so
    that officers can "determine in advance whether the conduct
    contemplated will implicate the Fourth Amendment" or art. 14
    (citation omitted).    See 
    id.
    Few courts have yet to reach the issue of race in the
    seizure analysis.     Among the few to have done so, the United
    States Courts of Appeals for the Ninth and Tenth Circuits have
    come to different conclusions about whether to include race in
    that analysis.
    The United States Court of Appeals for the Ninth Circuit
    has included race in the seizure analysis.     In United States v.
    Washington, 
    490 F.3d 765
    , 768-769 (9th Cir. 2007), the court
    concluded that recent well-publicized incidents in which police
    officers shot African-American citizens passed the requisite
    20
    threshold of objectivity and therefore were relevant to whether
    an African-American man had been seized.
    Courts in some other jurisdictions have stated that race is
    relevant to seizure, but have not undertaken a race-based
    analysis; in the circumstances of the cases confronting them,
    they have held that seizures occurred without considering race.
    See United States v. Smith, 
    794 F.3d 681
    , 687-688 (7th Cir.
    2015) (noting "relevance of race in everyday police encounters,"
    as well as "empirical data demonstrating the existence of racial
    profiling, police brutality, and other racial disparities in the
    criminal justice system"); State v. Jones, N.H Supreme Court,
    No. 2019-0057 at 6-7 (January 10, 2020) ("race is an appropriate
    circumstance to consider in . . . seizure analysis" [citation
    omitted]).
    Conversely, the United States Court of Appeals for the
    Tenth Circuit has determined that experiences with, and
    attitudes towards, police are not universal across racial
    groups, and therefore are not objective.   See United States v.
    Easley, 
    911 F.3d 1074
    , 1081-1082 (10th Cir. 2018), cert. denied,
    
    139 S. Ct. 1644
     (2019) (declining to consider race in seizure
    analysis); United States v. Little, 
    18 F.3d 1499
    , 1505 & n.7
    (10th Cir. 1994) (rejecting race as "general across-the-board
    categorization[]" in seizure analysis).    As the Tenth Circuit
    explained in Easley, supra at 1082,
    21
    "Requiring officers to determine how an individual's race
    affects her reaction to a police request would seriously
    complicate Fourth Amendment seizure law. As the government
    notes, there is no easily discernable principle to guide
    consideration of race in the reasonable person
    analysis. . . . There is no uniform life experience for
    persons of color, and there are surely divergent attitudes
    toward law enforcement officers among members of the
    population. Thus, there is no uniform way to apply a
    reasonable person test that adequately accounts for racial
    differences consistent with an objective standard for
    Fourth Amendment seizures. This distinguishes race from
    the Supreme Court's consideration of age in the reasonable
    person analysis in J.D.B. v. North Carolina, 
    564 U.S. 261
    [(2011)]."
    As discussed infra, we agree with the defendant in this
    case, based on factors other than race, that he was seized when
    Garney opened the cruiser door.   We therefore attempt to focus
    attention on the issue of race, while not establishing bright-
    line rules that potentially could do more harm than good.
    Accordingly, we do not decide here whether the race of a
    defendant properly informs the seizure inquiry.    See
    Commonwealth v. AdonSoto, 
    475 Mass. 497
    , 506 (2016), quoting
    Commonwealth v. Raposo, 
    453 Mass. 739
    , 743 (2009) ("We do not
    decide constitutional questions unless they must necessarily be
    reached"); Commonwealth v. Kulesa, 
    455 Mass. 447
    , 457 n.9
    (2009), quoting Commonwealth v. Paasche, 
    391 Mass. 18
    , 21 (1984)
    (same).
    c.    Application.   An officer generally does not objectively
    communicate that he or she would coerce an individual to stay
    merely by asking questions.   See Franklin, 456 Mass. at 820.
    22
    Thus, the officers here did not seize the defendant when they
    asked to talk with him, or when they explained that they wanted
    to know if he had seen or heard anything.   See Matta, 483 Mass.
    at 364 (no seizure where officer said "Hey, come here for a
    second"); Barros, 435 Mass. at 172 ("Hey you . . . I want to
    speak with you" was not seizure); Commonwealth v. Rock, 
    429 Mass. 609
    , 611 (1999) (no seizure where officer stepped out of
    vehicle, identified himself, and asked, "[C]an I talk to you for
    a second?"); Stoute, 422 Mass. at 789 (request that suspect
    "hold up a minute" was not seizure).
    The defendant's reaction to the officers, however, altered
    the nature of the encounter.   In response to the request to
    talk, the defendant said, "For what?"   He walked quickly away,
    and increased his speed as the interaction lengthened.    During
    his second, mumbled response, he began to look in various other
    directions.
    These actions communicated a desire to terminate the
    interaction, but the officers continued to follow their
    reluctant interlocutor for one hundred yards.   Their persistence
    came to a head when Garney opened the cruiser door, making clear
    that the officers were going to converse with the defendant
    notwithstanding his evident wishes to the contrary.   We agree
    with the defendant that, at that moment, he was seized.    See
    Barros, 435 Mass. at 175-176 (seizure occurred where officer
    23
    "le[ft] his cruiser and walk[ed] up to [defendant] after being
    rebuffed" and said, "Hey you.    I wanna talk to you.   Come
    here"); Commonwealth v. Evans, 
    87 Mass. App. Ct. 687
    , 691-692
    (2015) (although initial questioning from cruiser was not
    seizure, officer effected seizure by getting out of vehicle and
    continuing to question defendant).
    2.   Reasonable suspicion.     For an investigatory stop to
    have been constitutional under art. 14, police officers must
    have had "reasonable suspicion, based on specific and
    articulable facts, that the defendant had committed, was
    committing, or was about to commit a crime."     See Commonwealth
    v. Depina, 
    456 Mass. 238
    , 242 (2010).     See also Terry v. Ohio,
    
    392 U.S. 1
    , 21 (1968).
    The defendant maintains that the officers did not have
    reasonable suspicion to justify the stop, and that the judge
    erred in relying upon police testimony regarding the
    characteristics of an individual carrying a concealed firearm.
    The Commonwealth argues that even if we place the moment of
    seizure at the beginning of the chase, as we do, the officers at
    that point had reasonable, articulable suspicion that the
    defendant had committed a crime.     The Commonwealth points to the
    following factors to support this conclusion:    the proximity of
    the stop to a shooting, evidence that the defendant was carrying
    a firearm, and the defendant's nervous and evasive behavior.
    24
    The judge also found the "high crime" nature of the area to be
    probative.   We agree that there was reasonable suspicion, but
    for somewhat different reasons, primarily based on the proximity
    to a recent shooting and the indications that the defendant was
    carrying a firearm.
    a.    Proximity to a shooting.   We consistently have held
    that geographic and temporal proximity to a recent crime weigh
    towards reasonable suspicion in the over-all analysis.    See
    Depina, 
    456 Mass. at 246
    ; Commonwealth v. Riggins, 
    366 Mass. 81
    ,
    87 (1974) (reasonable suspicion was bolstered by fact that time
    and location of encounter "was consistent with the time
    necessary to travel there from the scene of the robbery").
    Here, the officers encountered the defendant thirteen minutes
    after the shooting, one-half mile distant from it.    It was a
    cold night, and the officers had not seen any other pedestrians
    on the nearby streets.    The defendant was walking away from the
    location of the shooting, with his hands in the pockets of his
    jacket.   The time and location was consistent with the theory
    that he had been present at the shooting and had walked to
    Dewitt Drive in the intervening minutes.    These facts track
    closely with those in Depina, supra, where the defendant was
    found three blocks from the shooting, ten minutes after it had
    occurred.    Therefore, his proximity to the crime supported
    reasonable suspicion.    Contrast Warren, 475 Mass. at 536 (no
    25
    reasonable suspicion where defendant was stopped twenty-five
    minutes after crime, one mile away).
    Additionally, the crime being investigated here was a
    shooting that had left the victim in critical condition.      These
    circumstances indicated a potential ongoing risk to public
    safety, and therefore weighed in favor of reasonable suspicion.
    See Depina, 
    456 Mass. at 247
     ("gravity of the crime" supported
    reasonable suspicion); Commonwealth v. Hilaire, 
    92 Mass. App. Ct. 784
    , 791 (2018), quoting Commonwealth v. Meneus, 
    476 Mass. 231
    , 239 (2017) (reasonable suspicion was supported by "fact
    that the crime under investigation was a shooting, with
    implications for public safety"); Commonwealth v. Doocey, 
    56 Mass. App. Ct. 550
    , 557 (2002) ("in circumstances where [a] gun
    presents an imminent threat because of shots just fired, or
    likely to be fired, . . . there is an edge added to the
    [reasonable suspicion] calculus").     But see Meneus, supra ("we
    have not gone so far as to carve out a public safety
    exception").
    In sum, although the defendant's proximity to a recent
    shooting was not sufficient alone to establish reasonable
    suspicion, it provided significant support.
    b.   Evidence of a firearm.   The officers testified to
    several observations that indicated that the defendant might
    have been carrying a firearm.   Before discussing the probative
    26
    value of that testimony, we address the defendant's evidentiary
    challenges.
    After filing his motion to suppress, the defendant sought a
    Daubert-Lanigan hearing to exclude from the hearing on the
    motion all testimony concerning the officers' training and
    experience in recognizing individuals who are carrying concealed
    firearms.   See Daubert v. Merrell Dow Pharms., Inc., 
    509 U.S. 579
     (1993); Commonwealth v. Lanigan, 
    419 Mass. 15
     (1994).     In
    support of his motion, the defendant offered testimony by Sweet
    regarding the scientific literature, and the absence thereof, on
    the detection of concealed firearms.     The Commonwealth, in turn,
    moved to exclude Sweet's testimony as not meeting the standards
    set forth in Daubert and Lanigan.   The judge denied both
    motions, and allowed both the officers' testimony and Sweet's
    testimony to be introduced.   Ultimately, the judge's decision
    relied significantly on testimony by the officers, and largely
    discredited Sweet's opinion testimony.    We review the judge's
    decisions on the introduction or exclusion of evidence for abuse
    of discretion.   See Canavan's Case, 
    432 Mass. 304
    , 311 (2000).
    See also United States v. Bunnell, 
    280 F.3d 46
    , 49 (1st Cir.
    2002) (reviewing admission of testimony at suppression hearing
    for abuse of discretion).
    27
    The defendant argues that the officers' testimony based on
    their training and experience in identifying concealed weapons
    was inadmissible expert testimony under Daubert and Lanigan.
    "[T]he rules of evidence normally applicable in criminal
    trials do not operate with full force at hearings before the
    judge to determine the admissibility of evidence."      United
    States v. Matlock, 
    415 U.S. 164
    , 172-173 (1974).     See Mass. G.
    Evid. § 1101(d) (2020).   When deciding a question of
    admissibility at a hearing on a motion to suppress, "the court
    is not bound by the law of evidence, except that on privilege."
    Mass. G. Evid. § 104(a) (2020).8   See Bourjaily v. United States,
    
    483 U.S. 171
    , 178 (1987) (Federal rules of evidence "allow[] the
    trial judge [in suppression hearings] to consider any evidence
    whatsoever, bound only by the rules of privilege"); Bunnell, 
    280 F.3d at 49
    , citing United States v. Schaefer, 
    87 F.3d 562
    , 570
    (1st Cir. 1996) (same).   This policy is based on the view that a
    "judge is much less likely than a lay jury to be intimidated by
    claims of scientific validity into assigning an inappropriate
    evidentiary value to [particular] evidence" (citation omitted).
    8 The Reporter's Note, however, arguably is inconsistent
    with this statement; the note provides that, "[w]hile out-of-
    court statements are admissible as to the determination of
    probable cause or the justification of government action, other
    evidence that would be incompetent under the rules of evidence
    is not admissible at suppression hearings." See Mass. G. Evid.
    § 1101 note (2020).
    28
    United States v. Posado, 
    57 F.3d 428
    , 435 (5th Cir. 1995).     At a
    hearing on a motion to suppress, judges should "err on the side
    of considering more, not less, information" and then determine
    the credibility, reliability, and weight to be applied to that
    evidence.   See United States v. Stepp, 
    680 F.3d 651
    , 669 (6th
    Cir. 2012) (Daubert requirements are inapplicable in suppression
    hearing).   Therefore, the judge did not err in allowing the
    admission of the challenged evidence at the suppression hearing.
    The defendant argues also that the judge erred by
    dismissing Sweet's testimony regarding the threat study as
    "unhelpful."   The study reported that police officers were no
    better than lay people at identifying concealed weapons in video
    recordings.    The judge, however, found the literature on threat
    detection to be in its infancy.   Indeed, Sweet herself testified
    that the threat study, which was introduced in evidence, was the
    only study of its kind.    The study involved 107 people who each
    watched eight video recordings and attempted to identify whether
    the individuals in the recordings were carrying firearms.      In
    addition to the limitations inherent in relying upon only a
    single study involving a small number of individuals, the study
    itself noted several limitations in its design, including the
    lack of physiological stress on the part of those carrying the
    firearms, and a failure "to consider several environmental,
    contextual, and personal factors that could influence judgments
    29
    of concealment."   See Sweet, 41 Law and Human Behavior at 419.
    Moreover, the officers in the study had not been trained in the
    detection of concealed firearms.    Thus, the judge did not abuse
    his discretion by giving little weight to the study.
    The judge also decided that the six studies on implicit
    bias and stereotype threat were of little assistance because
    they were not authored by Sweet, and because they were not
    sufficiently related to her research.    This decision was not an
    abuse of discretion.    See Gomes, 453 Mass. at 509 (motion judge
    decides weight and credibility).
    Finally, the defendant contends that the officers'
    testimony, even if properly admitted, was unreliable and
    therefore should not have factored in the judge's decision.
    Both officers explained their length of service, and their
    training and experience with detecting individuals carrying
    concealed firearms.    See Commonwealth v. Kennedy, 
    426 Mass. 703
    ,
    706 (1998) ("We prefer more extended testimony on an officer's
    'inferential process'" [citation omitted]).    They then provided
    specific and articulable observations, noted infra, that the
    defendant's behavior was consistent with that of individuals
    carrying concealed firearms.    The judge did not abuse his
    discretion in relying upon the officers' testimony.    See Matta,
    483 Mass. at 366 n.8 ("when an officer relies on his or her
    training and experience to draw an inference or conclusion about
    30
    an observation made, the officer must explain the specific
    training and experience that he or she relied on and how that
    correlates to the observations made").
    In challenging the judge's reliance on the officers'
    testimony, the defendant points to Sweet's testimony that there
    is no scientific literature to support an inference, based on
    the facts known to the officers when they were driving beside
    him, that the defendant was carrying a firearm.     Accordingly,
    the defendant argues that the officers' testimony was
    unreliable.   The judge, however, did not find Sweet's testimony
    credible and reliable.    Even if he had, Sweet's testimony would
    not have shown affirmatively that the officers' testimony was
    false; rather, she testified that there was no scientific
    literature to support it.
    With respect to the evidence available to the officers, the
    following evidence that the defendant was carrying a firearm
    weighs towards reasonable suspicion.     The officers observed that
    the defendant was holding in his pocket an object that was
    consistent with the size of a firearm.     See Rock, 429 Mass.
    at 612 ("officers saw a pronounced bulge protruding under the
    defendant's shirt").     The defendant kept his hands pressed
    against his body, which, based on the officers' training and
    experience, indicated that he might be trying to conceal a
    weapon.   See Commonwealth v. Resende, 
    474 Mass. 455
    , 461 (2016)
    31
    (officer "observed the defendant holding his hand at his waist
    in a manner that [officer] believed from his training and
    experience was consistent with someone holding a gun").      The
    defendant proceeded to turn his body away from the officers in a
    manner that blocked them from seeing the object.   See Resende,
    supra at 461; Commonwealth v. DePeiza, 
    449 Mass. 367
    , 371
    (2007); Rock, 429 Mass. at 612.
    c.   Nervous and evasive behavior.   The Commonwealth argues
    that the defendant behaved nervously and evasively, thereby
    contributing to reasonable suspicion.    Specifically, the
    defendant did not make eye contact with the police throughout
    the interaction.   He walked quickly, speeding up as the police
    continued to follow him, and he started looking in various
    directions, which indicated to the officers that he might
    attempt to flee.
    In Warren, 475 Mass. at 539, we noted a "pattern of racial
    profiling" documented in the FIO reports from the Boston Police
    Department.   Based on this pattern, we concluded that the flight
    of an African-American man from police "is not necessarily
    probative of . . . consciousness of guilt."   Id. at 540.    As
    discussed, supra, this pattern of racial profiling has been
    confirmed by more recent FIO reports.    Even if this blight were
    eradicated today, a long history of race-based policing likely
    will remain imprinted on the group and individual consciousness
    32
    of African-Americans for the foreseeable future.    See
    Commonwealth v. Phillips, 
    413 Mass. 50
    , 53 (1992) (describing
    how informal policy of Boston police created "martial law" for
    some young African-Americans).   See also Terry, 
    392 U.S. at
    14
    n.11 ("field interrogations are a major source of friction
    between the police and minority groups" [citation omitted]);
    Henning, The Reasonable Black Child:    Race, Adolescence, and the
    Fourth Amendment, 
    67 Am. U. L. Rev. 1513
    , 1531 (2018) ("many
    [B]lack youth . . . transfer negative attitudes and resentments
    about the police from one generation to the next as youth
    internalize the negative experiences of their community").
    Thus, the reasoning of Warren remains relevant to the
    analysis of reasonable suspicion.    That reasoning applies
    equally to other types of nervous or evasive behavior in
    addition to flight.   Just as an innocent African-American male
    might flee in order to avoid the danger or indignity of a police
    stop, the fear of such an encounter might lead an African-
    American male to be nervous or evasive in his dealings with
    police officers.    See Warren, 475 Mass. at 540.   We therefore
    significantly discount the weight of the defendant's nervous and
    evasive behavior.
    d.   "High crime" area.   The officers testified regarding
    recent crime in the area of the shooting and their encounter
    with the defendant, and the judge factored this testimony into
    33
    his analysis.    The characterization of an area as "high crime"
    cannot justify the diminution of the civil rights of its
    occupants.   See United States v. Wright, 
    485 F.3d 45
    , 54 (1st
    Cir. 2007) (noting concern that "high crime" could be "used with
    respect to entire neighborhoods or communities in which members
    of minority groups regularly go about their daily business"
    [citation omitted]).     To guard against this risk, we consider
    this factor only if the "high crime" nature of the area has a
    "direct connection with the specific location and activity being
    investigated."     See Commonwealth v. Torres-Pagan, 
    484 Mass. 34
    ,
    41 (2020), citing Wright, 
    supra at 53-54
    .
    Here, the officers testified that there had been an ongoing
    feud between gangs in the area.     The police report, which was
    introduced in evidence, listed the incident numbers of other
    police reports of alleged gang-related crimes in the vicinity in
    the months prior to the shooting.     The dates, precise locations,
    and alleged perpetrators of those incidents were not provided.
    We are skeptical that these previous crimes, without additional
    details, demonstrate a "direct connection" with the defendant or
    the shooting at issue, so we do not consider the "high crime"
    nature of the area in our analysis.
    e.   Weight.     As discussed, we do not give much weight to
    the defendant's nervous and evasive behavior.    We do afford
    significant weight to the defendant's proximity to the shooting
    34
    and the indications that he might have been carrying a firearm.
    Although the facts of this case present a close question, we
    conclude that there was sufficient evidence to establish a
    reasonable, articulable suspicion.
