    BARRON, Circuit Judge.       Ernest Fields ("Fields") pleaded
    guilty to being a felon in possession of a firearm and ammunition.
    On appeal he contends that his conviction must be overturned
    because     the   police    obtained    the     firearm   and   ammunition   in
    consequence of a violation of the Fourth Amendment.               Fields also
    appeals his sentence.        He contends that it must be vacated because
    the District Court mistakenly concluded that a United States
    Sentencing Guidelines (the "Guidelines") enhancement for career
    offenders applied to him.        We affirm the conviction but vacate and
    remand the sentence.
    I.
    On April 10, 2013, Fields was indicted under 18 U.S.C.
    § 922(g)(1) on one count of being a felon in possession of a
    firearm and ammunition.        The indictment arose out of an encounter
    between Fields and the Boston police in the early morning hours of
    September 12, 2012.        The encounter occurred near Madison Park High
    School in the Roxbury neighborhood of Boston.               It lasted several
    minutes.
    At first, the encounter involved only Fields and one
    Boston police officer.         But that officer eventually called for
    backup, and four additional officers arrived on the scene.                   At
    some point after those officers arrived, the police conducted a
    pat-frisk    of   Fields.       The    police    acquired   the   firearm    and
    ammunition during that frisk.
    - 2 -
    Following the indictment, Fields sought to suppress the
    firearm and ammunition on the ground that the police had acquired
    that evidence only because they had seized Fields without a legally
    sufficient basis for doing so.    The District Court, after holding
    a hearing, denied Fields's motion.       United States v. Fields, No.
    13–10097–DJC, 
    2014 WL 2616636
    (D. Mass. June 11, 2014).
    The District Court ruled that Fields was seized neither
    when the officer that he initially encountered spoke with him nor
    when the four officers later arrived as backup. The District Court
    did hold that the police seized Fields later on in the encounter,
    when the police physically subdued Fields in order to conduct a
    pat-frisk of him.    At that time, the District Court concluded, the
    police had a lawful basis to seize and search Fields because the
    police had probable cause to arrest him for assault and battery on
    a police officer.1
    On June 12, 2014, Fields pleaded guilty to the felon-
    in-possession count.      In doing so, he reserved his right to
    challenge on appeal the District Court's denial of his motion to
    suppress.
    1 The District Court also ruled in the alternative that
    suppression was not warranted because even if the seizure did occur
    at the time the four backup officers arrived on the scene, the
    police would have inevitably discovered the firearm and the
    ammunition.
    - 3 -
    On October 22, 2014, the District Court sentenced Fields
    to a term of imprisonment of 60 months, to be followed by three
    years of supervised release.          In selecting the sentence, the
    District Court referenced the Guidelines sentencing range that had
    been set forth in Fields's pre-sentence report ("PSR").
    The PSR calculated that range as follows.                   The PSR
    assigned Fields a base offense level ("BOL") under the Guidelines
    of 24.    In calculating Fields's BOL, the PSR applied U.S.S.G.
    § 2K2.1(a)(2).    That guideline provides for an enhancement to the
    defendant's BOL if the defendant satisfies certain career offender
    requirements.    Under that enhancement, "if the defendant committed
    any part of the instant offense subsequent to sustaining at least
    two felony convictions of . . . a crime of violence," the defendant
    shall be assigned a BOL of 24.2       U.S.S.G. § 2K2.1(a)(2) (emphases
    added).
    The    PSR   identified    the    following   two   prior    felony
    convictions of Fields as convictions of a "crime of violence": his
    conviction for resisting arrest for which he was sentenced in
    September 2010, and at least one of a set of convictions that arose
    out of a single incident and for which Fields had received a single

    three-level downward adjustment for acceptance of responsibility.
    U.S.S.G. § 3E1.1(b).
    - 4 -
    sentence in July 2010.3        Those July 2010 convictions included
    convictions under Massachusetts law for assault with a dangerous
    weapon    ("ADW"),   assault   and   battery    with   a   dangerous   weapon
    ("ABDW"), assault and battery on a police officer ("ABPO"), and
    resisting arrest.4
    The District Court concluded that the Guidelines range
    reflected in the PSR was properly calculated at 70-87 months, which
    was consistent with Fields's having a BOL of 24 and a criminal
    history category of V.     But the District Court also concluded that
    a downward departure in Fields's criminal history category was
    warranted because that category, although properly calculated,
    substantially overrepresented the seriousness of Fields's criminal
    history.    See U.S.S.G. § 4A1.3(b).         That departure translated to
    a Guidelines range of 60-71 months, which was consistent with
    applying a BOL of 24 and a criminal history category of IV to
    Fields.    The District Court then sentenced Fields to a term of
    3 The record does not disclose the dates of conviction for
    the convictions referenced.     References to the "September 2010
    conviction" and the "July 2010 convictions" thus refer to the dates
    of sentencing.
    4 The PSR also assigned Fields a criminal history score of 12
    under the Guidelines, which translated to a criminal history
    category of V. In calculating Fields's criminal history score,
    the PSR applied a sentencing enhancement that resulted in Fields's
    receiving three criminal history points because his July 2010
    convictions for ABDW, ABPO, and resisting arrest were classified
    as convictions of a crime of violence under the career offender
    guideline. See U.S.S.G. § 4A1.1(e).
    - 5 -
    imprisonment -- 60 months -- that was at the low end of that lower
    range.
    On appeal, Fields challenges both his conviction and his
    sentence.     He challenges his conviction on the ground that the
    District Court erred in denying his motion to suppress the firearm
    and ammunition.      Fields challenges his sentence on the ground that
    the District Court erred in classifying his prior convictions as
    convictions of a crime of violence for purposes of calculating his
    BOL under the Guidelines.
    We first consider Fields's challenge to his conviction.
    We then turn to his challenge to his sentence.
    II.
    Fields    argues   that    his    conviction    must     be   vacated
    because the District Court erred in denying his motion to suppress
    the firearm and ammunition.           "When reviewing a challenge to the
    district court's denial of a motion to suppress, we view the facts
    in the light most favorable to the district court's ruling on the
    motion, and we review the district court's findings of fact and
    credibility determinations for clear error."                United States v.
    Fermin, 
    771 F.3d 71
    , 76 (1st Cir. 2014) (quoting United States v.
    Camacho, 
    661 F.3d 718
    , 723 (1st Cir. 2011)). We review conclusions
    of   law,   including   the    ultimate      conclusion    whether    a   seizure
    occurred, de novo.       
    Camacho, 661 F.3d at 724
    .           Fields bears the
    burden of establishing that he was seized.            
    Id. - 6
    -
    A.
    The Fourth Amendment prohibits "unreasonable searches
    and seizures."   U.S. Const. amend. IV.          "The protections of the
    Fourth Amendment apply not only to traditional arrests, but also
    to those brief investigatory stops generally known as Terry stops."
    
    Camacho, 661 F.3d at 724
    .     An officer may ordinarily execute a
    Terry stop without running afoul of the Fourth Amendment if the
    officer   "reasonably   suspects    that   the   person    apprehended   is
    committing or has committed a crime."      
    Id. at 726
    (quoting Arizona
    v. Johnson, 
    555 U.S. 323
    , 323 (2009)).
    The police need not have taken physical custody of a
    person in order to be deemed to have effected a Terry stop for
    which at least reasonable suspicion is required.              Such a stop
    instead may occur merely upon law enforcement making what the
    Supreme Court has termed a "show of authority."        See United States
    v. Mendenhall, 
    446 U.S. 544
    , 553-54 (1980).               Such a "show of
    authority" occurs, however, only when "in view of all of the
    circumstances surrounding the incident, a reasonable person would
    have believed that he was not free to leave."          
    Id. at 554.
       And,
    further, the show of authority effects a seizure only when the
    defendant actually yields or submits to the show of authority.
    See California v. Hodari D., 
    499 U.S. 621
    , 628-29 (1991).
    We appreciate "that few people . . . would ever feel
    free to walk away from any police question."              United States v.
    - 7 -
    Cardoza, 
    129 F.3d 6
    , 16 (1st Cir. 1997).                 But that reality
    obviously   does   not    mean    that    every   police-citizen    encounter
    results in a show of authority for Fourth Amendment purposes.             See
    
    id. The "free
    to leave" test thus focuses on whether the conduct
    of    law   enforcement    "objectively       communicate[s]       that   [law
    enforcement] is exercising [its] official authority to restrain
    the individual's liberty of movement."            
    Id. (emphasis added).
    The Supreme Court has identified several characteristics
    of an encounter with law enforcement that might indicate that there
    was a show of authority.         These characteristics include: "[1] the
    threatening presence of several officers, [2] the display of a
    weapon by an officer, [3] some physical touching of the person of
    the citizen, or [4] the use of language or tone of voice indicating
    that compliance with the officer's request might be compelled."
    
    Mendenhall, 446 U.S. at 554
    .
    B.
    Fields's challenge to the District Court's ruling on his
    suppression motion rests on his contention that he was not "free
    to leave" -- and thus that a seizure occurred due to a "show of
    authority" -- when the four officers arrived at the scene in
    response to a call for backup from the officer Fields initially
    encountered.   According to Fields, the five officers at that point
    made the requisite show of authority even though they lacked a
    lawful basis to seize him.
    - 8 -
    The government responds in part by arguing that it does
    not matter whether the arrival of the officers did result in a
    show of authority, because the police had reasonable suspicion to
    justify Fields's seizure even at that point in the encounter.               To
    support this conclusion, the government argues that the first
    officer who encountered Fields reasonably suspected that Fields
    had previously trespassed on public property and thus that this
    officer had reasonable suspicion to detain Fields even at that
    time.
    There is a question whether the government is right that
    the police would have been justified under the Fourth Amendment in
    seizing Fields on the basis of reasonable suspicion that he had
    committed that trespassing offense, given that it was a completed
    non-felony offense.      Compare Gaddis v. Redford Township, 
    364 F.3d 763
    , 771 n.6 (6th Cir. 2004) ("Police . . . may make a stop when
    they have reasonable suspicion of a completed felony, though not
    of a mere completed misdemeanor [or lesser infraction]."), with
    United States v. Moran, 
    503 F.3d 1135
    , 1141 (10th Cir. 2007)
    (noting the circuit split on whether reasonable suspicion of a
    completed non-felony offense can justify a Terry stop under the
    Fourth Amendment and declining to adopt the Sixth Circuit's per se
    rule).   But we need not decide that question.          And that is because
    we   affirm    the   District   Court's    conclusion    that   no   show   of
    - 9 -
    authority -- and thus no seizure -- had occurred as of the time
    that the four backup officers arrived on the scene.
    To    explain   why    we    reach    this   conclusion,   we    first
    describe the encounter between Fields and the police in some
    detail, as the determination of the point at which a show of
    authority occurs is necessarily dependent on the particular facts
    in each case.         We then explain why there was no error in the
    District Court's conclusion that the facts do not suffice to
    demonstrate that Fields has met his burden of showing that there
    was a show of authority -- and thus a seizure -- at the time that
    the backup officers arrived on the scene.
    C.
    In describing what happened that night, "we relate the
    facts 'as the trial court found them, consistent with record
    support.'"        United States v. Ford, 
    548 F.3d 1
    , 2 (1st Cir. 2008)
    (quoting United States v. Ruidiaz, 
    529 F.3d 25
    , 27 (1st Cir.
    2008)).     The encounter began in the early hours of September 12,
    2012.     Officer      Steven      Dodd   and     other   police   officers   were
    investigating a complaint that a group of people had gathered near
    Madison Park High School and had intended to engage in drug
    activity.
    Following the receipt of that complaint, Officer Dodd
    and his team briefly caught sight of a group of eight to ten
    individuals in that area.             But the officers lost track of the
    - 10 -
    group.   Officer Dodd therefore radioed to other officers in the
    area to seek their help in locating a group that he reported was
    heading from the front of the high school toward Roxbury Heritage
    State Park and Roxbury Street.
    Officer Joseph Fisher, who was working a routine patrol
    at the time, responded to the call.   He parked his police cruiser
    on the east end of Roxbury Street so that it was facing the
    direction of the Roxbury Heritage State Park.    Soon thereafter,
    Officer Fisher observed a group of six to eight individuals
    traveling from the state park area to Roxbury Street.
    At that point, Fields appeared to break off from the
    group that had just emerged onto Roxbury Street.        Fields then
    headed in the direction of Officer Fisher while the rest of the
    group headed in the opposite direction.   As Fields passed Officer
    Fisher's police cruiser, Officer Fisher got out of the car.
    Officer Fisher then proceeded to the rear of the vehicle (driver's
    side), and called out to Fields in a conversational tone, "Hey,
    what's going on tonight?"
    Upon hearing Officer Fisher's question, Fields turned
    around, walked back a few steps toward the rear of the cruiser
    (passenger's side), and proceeded to speak with Officer Fisher.
    Officer Fisher at that point made a few general inquiries of
    Fields, including asking Fields where he was coming from and where
    he was going.
    - 11 -
    The conversation quickly became "one-sided," however.
    Fields asserted that he was not comfortable with the police; that
    police made him nervous; that police had killed someone in the
    South End; and that Officer Fisher would need a reason to search
    him.
    Officer    Fisher     observed    that    Fields    was    becoming
    increasingly agitated.       "At this point, [Officer Fisher] had made
    no commands to Fields, had not requested any identification, had
    no physical contact with [Fields], had not blocked [Fields's] path
    down the street and . . . had kept his firearm holstered throughout
    the exchange."   Fields, 
    2014 WL 2616636
    , at *2.
    According to the District Court, Officer Fisher became
    concerned about the "nature and tone" of Fields's comments and
    Fields's general behavior, and so the officer called for backup by
    using the radio in his tactical vest.         
    Id. Specifically, Officer
    Fisher radioed that he was "off with one on Roxbury Street by
    myself."
    Within    about   a   minute,    four    other    police   officers
    (including Officer Dodd) arrived on the scene.              They emerged from
    an area near the front of the cruiser.
    According to Officer Fisher's account, the officers
    positioned themselves at the sides of his police cruiser, such
    that neither the officers nor the police cruiser blocked Fields
    from proceeding down Roxbury Street toward Malcolm X Boulevard,
    - 12 -
    which was the direction in which Fields was originally traveling.
    Officer Dodd's testimony, although different in some respects from
    Officer Fisher's testimony, was also that none of the officers
    "stood directly in front of Fields."      
    Id. Thus, according
    to
    Officer Dodd's account, too, Fields could have continued down
    Roxbury Street toward Malcolm X Boulevard.
    None of the backup officers spoke to Fields.     Fields
    reiterated his nervousness and displayed more agitation during
    this portion of the encounter.   It was not until Fields lifted his
    shirt and inadvertently revealed that he had a knife on his person
    that the officers moved toward Fields and that Officer Dodd
    indicated that he was going to conduct a pat-frisk of Fields.
    Fields resisted the pat-frisk by pushing Officer Dodd's hands away
    twice.   Officer Fisher and Officer Andrew Hunter then moved in to
    assist Officer Dodd by pinning Fields's arms to his side, thereby
    enabling Officer Dodd to conduct a pat-frisk of Fields.5
    D.
    Fields contends that the presence of multiple officers,
    the formation of the officers, and the calling of backup by Officer
    Fisher in Fields's presence, in combination, constituted a "show
    of authority" and thus converted the encounter at that point into
    5 Officers Dodd and Hunter were wearing plainclothes with
    Boston Police badges while Officers Fisher, Jose Dias, and Michael
    MacDougall were in uniform at the time in question.
    - 13 -
    a Terry stop for which reasonable suspicion was required.                 But the
    District   Court      concluded   otherwise    on   the    basis   of   all   the
    circumstances of the encounter described by the testimony at the
    suppression hearing.         We do not see a basis for overturning the
    District Court's ruling.
    It    is   well   established     that   the   absence    of   police
    commands or any sort of verbal demonstration of authority weighs
    against the conclusion that there has been a show of authority
    sufficient to effect a seizure.        Compare United States v. Drayton,
    
    536 U.S. 194
    , 200-01 (2002) ("Law enforcement officers do not
    violate    the   Fourth      Amendment's     prohibition     on    unreasonable
    seizures merely by approaching individuals on the street or in
    other public places and putting questions to them if they are
    willing to listen."), and 
    Cardoza, 129 F.3d at 16
    (noting as
    significant in finding no seizure the fact that the officer did
    not ask defendant to stop or to approach police car), with United
    States v. Espinoza, 
    490 F.3d 41
    , 49 (1st Cir. 2007) (finding
    seizure where single officer approached defendant's vehicle and
    asked defendant, in a commanding tone, to shut off engine).                 It is
    thus significant that the District Court found that there were no
    such demonstrations here.
    The testimony at the hearing supports the finding by the
    District Court that the verbal exchange between Fields and Officer
    Fisher was, on the whole, dominated and perpetuated by Fields
    - 14 -
    himself.    Moreover, the District Court supportably found that
    Officer Fisher, to the extent he did speak to Fields, merely asked
    general questions in a conversational way.
    Similarly, the record supports the District Court's
    finding that, prior to the sighting of the knife, none of the four
    backup officers spoke to Fields at all.     Thus, although the backup
    officers were on the lookout for illegal group activity, the record
    accords with the District Court's finding that -- at the relevant
    time -- none of those officers made any comments to Fields that
    indicated that they were treating Fields as a potential suspect
    or, more directly, that Fields should not leave.
    The record also backs up the District Court's findings
    that none of the officers physically touched Fields, brandished
    their weapons, or, after arriving on the scene, moved toward Fields
    at any point prior to the sighting of the knife.      These factors,
    too, weigh against the conclusion that a seizure occurred at the
    time that Fields contends one occurred.     See 
    Mendenhall, 446 U.S. at 554
    .
    To be sure, the presence of five police officers and the
    formation of these officers are certainly "important" features of
    the encounter.     See United States v. Berryman, 
    717 F.2d 651
    , 655
    (1st Cir. 1983).    And we have said in dicta that "[i]t is not clear
    that a reasonable person, surrounded by five police officers, would
    believe that he was free to leave."      
    Fermin, 771 F.3d at 77
    .   But
    - 15 -
    whether a person is "surrounded" is itself a judgment to be made
    from the facts of each case.           After all, "the presence of multiple
    officers does not automatically mean that a stop has occurred."
    United States v. Goddard, 
    491 F.3d 457
    , 461 (D.C. Cir. 2007) (per
    curiam); see also 
    Ford, 548 F.3d at 5
    .
    In this case, the District Court supportably found that
    Fields was not meaningfully restricted in his field of movement in
    consequence of the arrival of the backup officers.6              In making that
    finding, the District Court relied in part on our decision in
    United States v. Smith, 
    423 F.3d 25
    (1st Cir. 2005).                    There, we
    held that the defendant was not "surrounded" by officers, because
    the officers -- in approaching the defendant while he was sitting
    on a wall with a telephone pole in front of him -- stood "where
    they had to" and because the defendant "could have moved in a
    variety of directions."           
    Smith, 423 F.3d at 30
    .
    Here, Fields, who was standing in front of a parked
    police cruiser at the time the backup officers arrived, appears to
    have       had   fewer   points   of   departure   from   the   scene   than   the
    defendant had in Smith.            But the officers' testimony about the
    6
    The District Court concluded that, whether Officer Dodd's
    or Officer Fisher's account of the positioning of the officers
    controls, "it remains the case that the officers, to assist Officer
    Fisher, had to stand somewhere in [Fields's] vicinity and could
    only do so around or behind the car and Fields still had point of
    egress either up or down, respectively, the street." Fields, 
    2014 WL 2616636
    , at *3.
    - 16 -
    positioning of the various parties, as well as the diagrams that
    the officers supplied depicting where the parties stood, accords
    with the District Court's determination that the positioning of
    the officers did not restrict Fields from walking in the direction
    in which he was originally traveling.                For that reason, the
    formation of the police officers in this case does not compel a
    finding that Fields was "surrounded" or that law enforcement
    objectively communicated to him that he was not free to leave the
    scene.        See Michigan v. Chesternut, 
    486 U.S. 567
    , 575 (1988)
    (finding no seizure in part because officers did not "block
    [defendant's]       course    [of   travel]    or   otherwise       control     the
    direction or speed of his movement"); 
    Camacho, 661 F.3d at 725
    (finding seizure in part because officers "intentionally blocked"
    the    path    on   which   defendant    was   traveling    with    their     Crown
    Victoria); 
    Ford, 423 F.3d at 25
    (finding no seizure in part because
    defendant, though restricted in his field of movement by the
    presence of two police officers and a telephone police, "could
    have moved in a variety of directions").
    Of course, Fields did not actually leave the scene
    despite the available path afforded him and the absence of any
    verbal signals from the police that he was obliged to stay.                     But
    that   is     not   determinative   of   whether    the    police    objectively
    communicated to Fields that he was required to stay.                  See Hodari
    
    D., 499 U.S. at 628
    ("[T]he test for existence of a 'show of
    - 17 -
    authority' is an objective one: not whether the citizen perceived
    that he was being ordered to restrict his movement, but whether
    the officer's words and actions would have conveyed that to a
    reasonable person.").       In fact, Fields similarly did not leave
    when he was initially in the presence only of Officer Fisher, yet
    Fields concedes that there was no show of authority at that point.
    There   remains    Fields's     contention     that    a    show   of
    authority occurred at the time he asserts because Officer Fisher
    called for backup and that call, coupled with the actual arrival
    of the four backup officers, objectively communicated to Fields
    that law enforcement was targeting him as a suspect and thus that
    he was not free to leave.     But the principal case upon which Fields
    relies for this contention, United States v. Beauchamp, 
    659 F.3d 560
    , 566-67 (6th Cir. 2011), involved very different facts.
    The court in that case concluded that a seizure occurred
    only after the defendant "walk[ed] away from the police two times"
    and was told to stop, turn around, and walk toward the police.
    
    Id. at 566.
       The Sixth Circuit, quite reasonably, determined that
    the   police   officers'    persistence    in   pursuing    the       defendant
    notwithstanding    the     defendant's    attempts   to    walk       away,   in
    combination with the request by one of the officers that the
    defendant stop, objectively communicated to the defendant that he
    was under investigation and thus that he was not free to leave.
    See 
    id. at 567.
    - 18 -
    Unlike in Beauchamp, however, the police did not follow
    Fields after he had walked away.         The police also did not at any
    point tell Fields not to leave.     The testimony at the suppression
    hearing reveals only that Officer Fisher asked Fields some general
    questions and that Officer Fisher, after becoming concerned with
    Fields's statements and seeming agitation, radioed that he was
    "off with one on Roxbury Street by myself."           The backup officers
    never spoke to Fields after they arrived.              Thus, "the police
    conduct involved here would not have communicated to the reasonable
    person an attempt to capture or otherwise intrude upon [the
    defendant's] freedom of movement" for the purpose of investigating
    criminal wrongdoing.    
    Chesternut, 486 U.S. at 575
    .
    Moreover, in a given encounter, there may be legitimate
    reasons for an officer to summon and maintain backup, such as
    ensuring    the   officer's   safety,    that   do    not   relate   to   the
    investigation (let alone detention) of a suspect.           The arrival of
    backup officers in response to a call for assistance thus may
    signal, depending on the facts, only that backup will remain on
    the scene in the event that the person who has encountered a lone
    police officer chooses to stay, rather than that such a person is
    not free to leave.     See State v. Thomas, 
    246 P.3d 678
    , 686 (Kan.
    2011) (noting that "a mere call for back-up does not automatically
    transform     all    citizen-law        enforcement     encounters        into
    investigatory detentions"); State v. Green, 
    826 A.2d 486
    , 499 (Md.
    - 19 -
    2003) ("That [law enforcement] called for back-up as a safety
    measure did not suddenly transform the consensual encounter into
    a seizure.").
    Here, during the radio call, even if heard by Fields (a
    point on which the District Court made no finding and on which the
    record is unclear), Officer Fisher did not state that he was asking
    for other officers to assist him in an effort to investigate
    whether Fields had been engaged in criminal activity.         Instead,
    Officer Fisher appeared to be communicating only a concern for his
    safety -- as evidenced by the words "by myself" -- due to the
    agitation that Fields was exhibiting in his presence.       So while a
    reasonable person in Fields's shoes could perceive that the four
    officers who arrived did so on his account and not due to pure
    happenstance, it does not follow that their arrival therefore
    objectively communicated to Fields that the police were targeting
    him in the Beauchamp sense.
    Indeed, a conclusion that the summoning and subsequent
    arrival of backup automatically -- and without regard to other
    facts   that    bear   on   the   nature   of   the   encounter   as   a
    whole -- constitutes a show of authority could have a distorting
    effect on an officer's decision about whether to take a precaution
    for his own safety.     Such an automatic rule would import into an
    officer's calculus about whether to call for backup a determination
    about whether there is a lawful basis to detain the person the
    - 20 -
    officer has encountered.    But the decision to detain someone so
    that he or she may not leave may be distinct from the decision to
    call for backup in order to ensure an officer's safety in the event
    that the person in question chooses to stay.    We thus decline to
    adopt a per se approach in this context.     Cf. Michigan v. Long,
    
    463 U.S. 1032
    , 1052 (1983) (noting, in concluding that police
    officers may, consistent with the Fourth Amendment, sometimes
    search the passenger compartments of a car for weapons during a
    lawful Terry stop, "we have not required that officers adopt
    alternate means to ensure their safety in order to avoid the
    intrusion involved in a Terry encounter").
    E.
    The totality of the circumstances test for assessing
    whether a show of authority has occurred "does not produce a
    crystalline landscape in our Fourth Amendment jurisprudence."
    
    Ford, 548 F.3d at 7
    .       "Th[at] test is necessarily imprecise,
    because it is designed to assess the coercive effect of police
    conduct, taken as a whole, rather than to focus on particular
    details of that conduct in isolation."     
    Chesternut, 486 U.S. at 573
    .
    But the burden is on Fields to establish the show of
    authority that is the necessary predicate for his claimed Fourth
    Amendment violation.   And under the totality of the circumstances
    test that we must apply, we do not on these facts see a basis for
    - 21 -
    overturning the District Court's conclusion that Fields failed to
    demonstrate that there was a show of authority at the time the
    four backup officers arrived on the scene -- a conclusion, we add,
    that the District Court reached only after a thorough consideration
    of the testimony and evidence presented at the suppression hearing.
    We thus affirm the District Court's decision to deny Fields's
    motion to suppress on the basis that there was no show of authority
    and consequently no unlawful seizure at the time that Fields
    contends one occurred.
    III.
    We now turn to Fields's challenge to his sentence.
    Before we address the merits of his challenge, though, we need to
    step back so that we can explain precisely what is in dispute --
    and what is not.
    Fields contends that the District Court erroneously
    subjected him to a particular career offender enhancement under
    the Guidelines, with the result that he was assigned too high of
    a   BOL   and   thus   too   high   of   a   Guidelines   sentencing   range.
    Specifically, Fields contends that the District Court erred in
    applying the enhancement set forth in U.S.S.G. § 2K2.1(a)(2), which
    provides for a BOL of 24 if the defendant has two prior convictions
    of a crime of violence under the career offender guideline. Fields
    argues that, in fact, none of his prior convictions qualified as
    convictions of a crime of violence under the career offender
    - 22 -
    guideline.    Fields thus contends that his BOL should have been 14,
    as that is the BOL that would have applied had Fields received no
    career offender enhancement.       See U.S.S.G. § 2K2.1(a)(6)(A).
    In response, the government agrees that the District
    Court's application of the sentencing enhancement set forth in
    U.S.S.G. § 2K2.1(a)(2) was erroneous.           The government takes that
    position because the District Court classified Fields's September
    2010 conviction for resisting arrest as a conviction of a crime of
    violence under the career offender guideline, and the government
    concedes on appeal that conviction cannot be so classified on this
    record.      The   government   also     agrees    with    Fields   that,    in
    consequence   of   this   error,   the   case     should   be   remanded    for
    resentencing.
    The government does not agree with Fields, however, that
    the BOL that should be applied to him on remand should be 14.
    Rather, the government contends that the BOL that should be applied
    to Fields on remand should be 20, which is the BOL that would apply
    to a defendant subject to the enhancement set forth in U.S.S.G.
    § 2K2.1(a)(4)(A).    The government contends that the District Court
    should apply that enhancement instead of the one set forth in
    U.S.S.G. § 2K2.1(a)(2), which was the Guidelines provision that
    the District Court applied below.               The enhancement that the
    government contends should apply on remand requires that the
    defendant have only one prior conviction of a crime of violence,
    - 23 -
    rather than the two such convictions required under U.S.S.G.
    § 2K2.1(a)(2).
    In practical terms, the dispute over the proper BOL to
    apply to Fields on remand matters in the following way.    Assuming
    that the District Court will again sentence Fields on the basis of
    a criminal history category of IV, Fields's Guidelines range would
    be 37-46 months on the government's view, which is the range
    consistent with a BOL of 20.     On that same assumption, Fields's
    Guidelines range would be 21-27 months on Fields's view, which is
    the range consistent with a BOL of 14.
    To support the application on remand of a BOL of 20, the
    government contends that Fields's July 2010 convictions for ADW
    and ABDW together "constitute one qualifying conviction [of] a
    'crime of violence'" under the career offender guideline, Gov. Br.
    55 (emphasis added), and that the enhancement set forth in U.S.S.G.
    § 2K2.1(a)(4)(A) therefore should apply.7    Given the government's
    argument, we need not decide whether both of Fields's July 2010
    convictions for ADW and ABDW qualify as convictions of a crime of
    violence.    We need only decide whether one of them does, as the
    7 The government does not ask us to conclude that Fields's
    July 2010 convictions for ADW and ABDW each constitute a conviction
    of a crime of violence and thus trigger the application of U.S.S.G.
    § 2K2.1(a)(2). Nor does the government argue that Fields's July
    2010   convictions   for   resisting   arrest  and   ABPO,   either
    independently or together, constitute convictions of a crime of
    violence.
    - 24 -
    only career offender enhancement that the government contends
    should apply would then be triggered.
    The District Court, in assessing Fields's BOL, did not
    pass on which of Fields's July 2010 convictions qualified as a
    conviction of a crime of violence.       The District Court thus did
    not specifically pass on whether either of Fields's July 2010
    convictions for ADW and ABDW qualified as a conviction of a crime
    of violence.     But the question is one of law, and the parties do
    not ask us to remand so that the District Court can pass on the
    question in the first instance.      We thus proceed to analyze the
    issue.
    Fields did not object below to the classification of any
    of his convictions as convictions of a crime of violence, see
    United States v. Ríos–Hernández, 
    645 F.3d 456
    , 462 (1st Cir. 2011)
    (noting that in such cases the plain-error standard of review
    ordinarily applies), but the government does not appear to ask us
    to apply the plain-error standard of review in evaluating Fields's
    challenge.     In any event, the standard of review is of little
    consequence here because, as we next explain, it is clear that at
    least one of Fields's July 2010 convictions for ADW and ABDW
    qualifies as a conviction of a crime of violence.8
    8 In his opening brief, Fields argued that the residual clause
    of the career offender guideline was unconstitutional and thus
    that his prior convictions did not qualify as convictions of a
    crime of violence. As the government notes, Fields did not address
    - 25 -
    A.
    In undertaking our inquiry, we start with -- and, it
    turns out, end with -- Fields's July 2010 conviction for ADW,
    because   we   conclude   that   that     conviction   does   qualify   as    a
    conviction of a crime of violence.           To explain why this is the
    case, we must first provide some background.
    The   career   offender      guideline   defines   a   "crime     of
    violence" as "any offense under federal or state law, punishable
    by imprisonment for a term exceeding one year, that (1) has as an
    element the use, attempted use, or threatened use of physical force
    against the person of another, or (2) is burglary of a dwelling,
    arson, or extortion, involves use of explosives, or otherwise
    the prospect that his prior convictions might nevertheless qualify
    as convictions of a crime of violence under the force clause of
    the career offender guideline.     It was only in his reply brief
    that Fields addressed that prospect.         Ordinarily, we treat
    arguments raised for the first time in an appellant's reply brief
    as waived. See United States v. Eirby, 
    515 F.3d 31
    , 36 n.4 (1st
    Cir. 2008).   It is unclear whether the government urges us to
    follow that practice here. In any event, we may make an exception
    where "justice so requires" and where the opposing party would not
    be unfairly prejudiced by our considering the issue. See United
    States v. Torres-Rosario, 
    658 F.3d 110
    , 116 (1st Cir. 2011). And
    here, we believe such an exception is proper. Johnson v. United
    States, 
    135 S. Ct. 2551
    (2015) (holding unconstitutional the
    residual clause contained in the definition of "violent felony" in
    the Armed Career Criminal Act), was decided after Fields's opening
    brief was filed. That decision made the force clause loom larger
    than otherwise would have been the case. Given that the government
    does not clearly press for waiver and that the arguments concerning
    whether Fields's prior convictions may qualify even under the force
    clause have now been fully joined by both parties, we see no
    prejudice to the government in considering such arguments.
    - 26 -
    involves conduct that presents a serious potential risk of physical
    injury to another."         U.S.S.G. § 4B1.2(a).          The first subparagraph
    of the career offender guideline is often referred to as the "force
    clause."    The trailing portion of the second subparagraph of that
    guideline    is    often    referred      to   as   the   "Guidelines'     residual
    clause."
    The parties agree that, in light of Johnson v. United
    States, 
    135 S. Ct. 2551
    (2015) ("Johnson II"), the residual clause
    of the career offender guideline is unconstitutional and thus may
    not be relied upon to classify a conviction as a conviction of a
    crime of violence under the career offender guideline.                    We assume
    without     deciding       that   the     parties     are      correct   in   their
    interpretation of the status of the residual clause.                     See United
    States v. Soto-Rivera, 
    811 F.3d 53
    , 59 (1st Cir. 2016).                          We
    therefore consider only whether the July 2010 ADW conviction
    qualifies as a conviction of a crime of violence under the force
    clause of the career offender guideline.
    To assess whether a conviction qualifies as a conviction
    of a crime of violence under that clause, we must apply what is
    known as the "categorical" approach.                 Under that approach, "we
    compare the statutory elements of the crime for which the defendant
    was previously convicted" -- "without regard to the specific facts"
    or   conduct      underlying      that     conviction     --    "with    Congress's
    definition of the type of crime that may serve as a predicate
    - 27 -
    offense" (that is, a crime of violence).              United States v. Fish,
    
    758 F.3d 1
    , 5 (1st Cir. 2014).          The object is to determine "whether
    the   conduct      criminalized   by    the     statute,    including   the   most
    innocent conduct, qualifies as a crime of violence."                Id.9
    The     Commonwealth's      ADW      statute     is   violated     by
    "[w]hoever, by means of a dangerous weapon, commits an assault
    upon another."       Mass. Gen. Laws ch. 265, § 15B(b).            Massachusetts
    law recognizes two theories of assault: attempted battery and
    threatened battery.       Commonwealth v. Porro, 
    939 N.E.2d 1157
    , 1163
    (Mass. 2010).       Battery has been defined as "harmful [or] offensive
    touching."      See Commonwealth v. Burke, 
    457 N.E.2d 622
    , 624 (Mass.
    1983). The crime of simple assault has thus been held to encompass
    both attempted and threatened offensive touching.                    See United
    States v. Martinez, 
    762 F.3d 127
    , 138 (1st Cir. 2014).                  ADW "adds
    one additional element, namely, that the assault was perpetrated
    by means of a dangerous weapon."          United States v. Whindleton, 
    797 F.3d 105
    , 112 (1st Cir. 2015) (quoting Commonwealth v. Melton, 
    763 N.E.2d 1092
    , 1096 (Mass. 2002)); see Commonwealth v. Appleby, 
    402 N.E.2d 1051
    , 1056-57 (Mass. 1980) (explaining the dangerous weapon
    element).    Finally, under either the attempted battery form or the
    9
    In certain circumstances involving divisible state statutes,
    the Court instructs us to apply what is known as the "modified
    categorical" approach. See Descamps v. United States, 
    133 S. Ct. 2276
    , 2281-82 (2013).   The government does not ask us to apply
    that approach here.
    - 28 -
    threatened battery form of ADW, the mens rea is one of specific
    intent, as the defendant must either intend to commit a battery or
    intend to put the victim in fear of an imminent battery.                 See
    
    Porro, 939 N.E.2d at 1163
    .
    Fields    contends     that     a    conviction       under   the
    Massachusetts ADW statute does not qualify as a conviction of a
    crime of violence under the force clause because the Massachusetts
    ADW   statute    criminalizes    attempted     or   threatened    offensive
    touching.10     Fields bases that contention solely on Johnson v.
    United States, 
    559 U.S. 133
    (2015) ("Johnson I").11          In Johnson I,
    the Court interpreted the force clause contained in the definition
    of "violent felony" in the Armed Career Criminal Act ("ACCA"), 18
    U.S.C. § 924(e)(2)(B)(i).       In doing so, the Court held that "the
    phrase 'physical force' means violent force -- that is, force
    10Fields does not contend that a conviction under the
    Massachusetts ADW statute fails to qualify as a conviction of a
    crime of violence because one may be convicted of that offense on
    the basis of only a mens rea of recklessness. And for good reason.
    As we recently concluded in the context of holding that "a
    conviction under [the Massachusetts ADW statute] includes a mens
    rea requirement sufficient to qualify the conviction as a predicate
    under the [Armed Career Criminal Act's] force clause," "under
    Massachusetts decisional law an ADW conviction requires that the
    use or threat of physical force be intentional." United States v.
    Hudson, No. 14–2124, 
    2016 WL 2621093
    , at *4-5 (1st Cir. May 9,
    2016). To the extent Fields contends that we suggested otherwise
    in United States v. Am, 
    564 F.3d 25
    (1st Cir. 2009), Hudson
    explains that "[a]lthough ABDW may be committed recklessly, we
    made clear in Am that ADW cannot be."

    capable of causing physical pain or injury to another person."
    
    Id. at 140
    (emphasis in original).          The Court thus concluded that,
    under the categorical approach, a conviction under a Florida simple
    battery statute did not qualify as a conviction of a "violent
    felony" within the meaning of the ACCA's force clause because that
    statute criminalized offensive contact such as an unconsented-to
    tap on the shoulder -- that is, conduct not involving "violent
    force."      
    Id. at 138.
    Fields's argument, however, is foreclosed by our recent
    decision in United States v. Whindleton, 
    797 F.3d 105
    (1st Cir.
    2015).       There, we held that a conviction under the Massachusetts
    ADW statute categorically qualified as a "violent felony" within
    the meaning of the ACCA's force clause, because "the element of a
    dangerous weapon imports the 'violent force' required by [Johnson
    I] into the otherwise overbroad simple assault statute."           
    Id. at 114.
      We reasoned that "the harm threatened by assault is far more
    violent than offensive touching when committed with a weapon that
    is designed to produce or used in a way that is capable of producing
    serious bodily harm or death."        
    Id. In other
    words, we concluded
    that     a     conviction   under    the     Massachusetts   ADW   statute
    categorically qualified as a violent felony under the ACCA's force
    clause because the minimum conduct criminalized by the statute
    qualifies as such by virtue of the dangerous weapon element.           See
    also United States v. Hudson, No. 14–2124, 
    2016 WL 2621093
    , at *4
    - 30 -
    (1st Cir. May 9, 2016) ("[W]e reaffirm that a Massachusetts ADW
    conviction meets the physical force requirement under the force
    clause of the ACCA.").
    True, this case involves the career offender guideline
    and the definition of "crime of violence" rather than the ACCA and
    the definition of "violent felony."     But we have expressly stated
    that "the terms 'crime of violence' under the career offender
    guideline and 'violent felony' under the ACCA are nearly identical
    in meaning, s[uch] that decisions construing one term inform the
    construction of the other."    United States v. Willings, 
    588 F.3d 56
    , 58 n.2 (1st Cir. 2009).   In fact, the force clause language of
    these provisions is identical.
    We thus conclude that, in light of Whindleton, Fields's
    July 2010 ADW conviction qualifies as a conviction of a crime of
    violence under the force clause of the career offender guideline.12
    12Fields points out that in United States v. Fish, this Court
    stated that a conviction under the Massachusetts ABDW statute would
    not qualify as a conviction of a crime of violence under the force
    clause of 18 U.S.C. § 16 because offensive touching does not (after
    Johnson I) "have 'as an element' the use of physical force." 
    758 F.3d 1
    , 9 (1st Cir. 2014).      Fields contends that Fish's logic
    extends to describe the nature of a conviction under the
    Massachusetts ADW statute, as that statute criminalizes attempted
    and threatened offensive touching. But the discussion of the force
    clause in Fish was dicta, as the Court based its holding on the
    residual clause in § 16 rather than the force clause. See 
    id. (noting that
    the government in Fish declined to argue that the
    defendant's prior conviction under the Massachusetts ABDW statute
    qualified as a conviction of a crime of violence under the force
    clause of § 16).    Thus, Fish's holding provides no support for
    Fields's argument.

    As   a    result,   we   vacate   and    remand      Fields's   sentence   for
    resentencing,       in   accordance     with   the    government's    request
    regarding the application of the sentencing enhancement set forth
    in U.S.S.G. § 2K2.1(a)(4)(A).13
    IV.
    For the reasons stated, we AFFIRM the District Court's
    denial of Fields's motion to suppress.            But we VACATE and REMAND
    for resentencing proceedings consistent with this opinion.
    13Fields does not appear to challenge, either in his opening
    brief or his reply brief, the District Court's classification of
    his prior convictions as convictions of a crime of violence for
    purpose of calculating his criminal history (as opposed to his
    BOL).
