    KAYATTA, Circuit Judge.            Convicted of being a felon in
    possession    of   a   firearm,       Verissimo      Tavares   appeals      both       the
    conviction and his sentence.             He claims that the district court
    erred   in   admitting     improper      and    prejudicial     expert      testimony
    concerning the absence of fingerprints on the gun that the jury
    found Tavares to have possessed.              He also claims that the district
    court erred in its guideline sentencing calculations by treating
    his convictions for resisting arrest and assault and battery with
    a dangerous weapon as "crime[s] of violence."                   For the following
    reasons, we affirm the conviction but remand for reconsideration
    of the sentence.
    I.     BACKGROUND
    Before dawn on August 4, 2013, two Boston police officers
    responded     to   a   dispatch       about     a    disturbance     in     a    Boston
    neighborhood.      As the officers dispersed the crowd, they heard
    gunshots     emanating    from    the    next       street;   when   they       went    to
    investigate the source, they caught sight of a figure, subsequently
    revealed to be Tavares, riding away on a motor scooter.                         A chase
    ensued.
    One of the pursuing police officers testified that he
    saw an object in Tavares's hands.               Another testified that he saw
    Tavares throw an object into the yard of a nearby dwelling at 71
    Clarkson Street.         The chase ended when the police took Tavares
    into custody. Searching for the hurled object, one of the officers
    - 2 -
    discovered a silver handgun in the yard of 71 Clarkson Street.
    Detectives were summoned to examine the firearm.        They determined
    that the handgun was a semiautomatic firearm, loaded with five
    rounds of ammunition.
    A federal grand jury charged Tavares as a felon in
    possession of a firearm. See 18 U.S.C. § 922(g)(1). He maintained
    his innocence, and the case went to trial. During the government's
    case in chief, several police officers testified about the chase,
    the arrest, and the retrieval of the firearm.       The government also
    presented the testimony of Richard Auclair, a fingerprint expert
    who held the position of Criminalist II in the Latent Print Unit
    (the Unit) at the Boston Police Department.         The defense rested
    without presenting any evidence.      The jury found Tavares guilty.
    In anticipation of sentencing, the probation department
    prepared a presentence investigation report (the PSR).        The Report
    recommended that the district court apply a four-level career
    offender enhancement under the sentencing guidelines, see U.S.S.G.
    §   2K2.1(a)(2),   based   on   a   conclusion   that   Tavares's   prior
    Massachusetts convictions for resisting arrest, see Mass. Gen.
    Laws ch. 268, § 32B(a), and for assault and battery with a
    dangerous weapon (ABDW), see 
    id. ch. 265,
    § 15A(b), were both
    "crime[s] of violence."    Tavares objected to the classification of
    his putative predicate offenses as crimes of violence under the
    residual clause of the sentencing guidelines' career offender
    - 3 -
    provision.      See U.S.S.G. § 4B1.2(a)(2) (Nov. 2014 ed.); 
    id. at §
    2K2.1(a)(2), cmt. n.1. Relying on our decisions in United States
    v. Glover, 
    558 F.3d 71
    , 80–81 (1st Cir. 2009), and United States
    v. Almenas, 
    553 F.3d 27
    , 33–34 (1st Cir. 2009), the district court
    overruled this objection.        In so doing, the district court deemed
    both prior convictions to be for crimes of violence under the
    residual clause.        The career offender enhancement, coupled with
    other adjustments not now in issue, yielded an advisory guideline
    range of 120-150 months, necessarily capped at 120 months by the
    ten year maximum applicable to the statute of conviction.                   See 18
    U.S.C. § 924(a)(2). Using the advisory guideline range as a "place
    to   start"    and    mulling   the    factors    enumerated     in    18   U.S.C.
    § 3553(a), the court imposed an 84-month prison term.                 This timely
    appeal followed.
    II.    ANALYSIS
    Challenging his conviction, Tavares argues that the
    district court erred, to his prejudice, by admitting over his
    objection a portion of Auclair's expert testimony.              Alternatively,
    he   argues    that   the   district    court     erred   in   calculating    his
    guideline sentencing range by counting his prior convictions as
    convictions for crimes of violence.              We address each argument in
    turn.
    - 4 -
    A.   Expert Testimony
    The principal issue at trial was whether Tavares had
    possessed the gun that the police found in the yard at 71 Clarkson
    Street.     Mainly through cross-examination and argument, Tavares
    sought to show that the government had not proved his possession
    of the weapon beyond a reasonable doubt.            To bolster this claim,
    he   suggested   (among   other   things)    that   the   police   officers'
    testimony about his involvement with the weapon was inconsistent;
    that the weapon, when found, did not bear his fingerprints and,
    thus, had not been in his hands; and that the police had rushed to
    judgment.     The   government    countered,   in    part,   by    presenting
    Auclair's testimony.
    After being duly qualified as a criminalist, Auclair
    testified about the significance of the fact that the examination
    of the gun by the police laboratory revealed only a very partial
    print that was itself insufficient to implicate or exclude Tavares.
    Auclair delineated the factors that affect recovery of usable
    prints (including the quality of ridge skin, the texture of the
    surface involved, the nature of print deposition, the treatment of
    the surface after print deposition, and environmental conditions).1
    After explaining the procedures used by the Unit to preserve
    1 In the context of fingerprint examination, "deposition" is the
    act of depositing something (such as sand, snow, or mud) on a
    surface, especially over a period of time.
    - 5 -
    prints, Auclair testified that the firearm removed from the yard
    at 71 Clarkson Street did not reveal any usable prints.
    So far, so good.         During direct examination, however,
    the prosecutor asked Auclair about the percentage of cases in which
    usable prints were recovered from examined firearms, that is, what
    percentage of examined guns were found to contain fingerprints
    with sufficient ridge detail to allow the authorities to make an
    identification.       Over the defendant's objection, the court allowed
    Auclair to opine, based primarily on the Unit's experience over a
    period of nearly nine years, that usable prints had been recovered
    from   approximately       16%   of   firearms   examined.       Under     cross-
    examination, Auclair explained that his opinion derived in part
    from a compilation of the Unit's fingerprint analyses completed by
    an intern:        we say "completed" because the Unit regularly kept
    such data on a series of spreadsheets, and the intern had simply
    updated those data and tabulated them.                Auclair could not say,
    however, either what procedures were used in the process of
    compilation or what oversight of the intern was provided by Unit
    staff.   He could opine, however, that the 16% figure was generally
    consistent with his own personal experience in examining hundreds
    of   guns.        After   cross-examination,     Tavares     moved    to   strike
    Auclair's opinion.        The court denied his motion.
    On    appeal,   Tavares    challenges     the   court's       rulings
    admitting    and     refusing    to   strike   this    portion   of   Auclair's
    - 6 -
    testimony.         Specifically,       Tavares       argues,    first,          that    the
    testimony    lacked    a   proper      foundation;      and     second,         that    the
    testimony was both not relevant and unfairly prejudicial.
    We review a trial court's decision to admit or exclude
    evidence for abuse of discretion.              See United States v. Pires, 
    642 F.3d 1
    , 10 (1st Cir. 2011); United States v. Stierhoff, 
    549 F.3d 19
    , 27 (1st Cir. 2008).           In carrying out this task, we afford
    "broad deference to the determination made by the district court
    as   to    the   reliability     and    relevance       of     expert      testimony."
    Beaudette v. Louisville Ladder, Inc., 
    462 F.3d 22
    , 25 (1st Cir.
    2006).     Absent a material error of law, we will not upset such a
    determination unless it appears that the district court "committed
    a meaningful error in judgment."                Ruiz-Troche v. Pepsi Cola of
    P.R. Bottling Co., 
    161 F.3d 77
    , 83 (1st Cir. 1998) (quoting
    Anderson v. Cryovac, Inc., 
    862 F.2d 910
    , 923 (1st Cir. 1988)).
    Against    this    backdrop,       we   turn     first     to      Tavares's
    argument    that    the    challenged     testimony         lacked     a     sufficient
    foundation.      The touchstone for the admission of expert testimony
    in federal court litigation is Federal Rule of Evidence 702.                            The
    rule provides in relevant part that, as a precursor to giving
    expert testimony, an expert must be "qualified . . . by knowledge,
    skill,    experience,      training,     or    education"       and     must      possess
    specialized      knowledge     that    "will    help    the    trier       of    fact    to
    understand the evidence or to determine a fact in issue."                         Fed. R.
    - 7 -
    Evid. 702.   The rule further demands that such opinion testimony
    rest on "sufficient facts or data."      
    Id. These requirements
    obligate a trial court to act as a
    gatekeeper in order to ensure, as a condition of admissibility,
    that   proffered   expert    testimony     rests   on   a   sufficiently
    trustworthy foundation.     See Daubert v. Merrell Dow Pharms., Inc.,
    
    509 U.S. 579
    , 597 (1993).    Where, as here, the factual basis of an
    expert's testimony is called into question, the district court
    must determine whether the testimony has "a reliable basis" in
    light of the knowledge and experience of the relevant discipline.
    Kumho Tire Co. v. Carmichael, 
    526 U.S. 137
    , 148 (1999) (quoting
    
    Daubert, 509 U.S. at 592
    ). We, in turn, review such determinations
    for abuse of discretion.     See 
    id. at 142.
    Tavares does not question Auclair's credentials as a
    fingerprint expert.    Nor could he:        Auclair earned a master's
    degree in forensics, underwent additional training upon joining
    the Unit, worked in the field for several years, and passed a
    series of annual proficiency tests.
    Expert testimony, however, can for the most part be no
    better than the information provided to the expert. That principle
    is summed up in the familiar phrase "garbage in, garbage out."
    Tavares says that, whatever Auclair's qualifications, he lacked a
    sufficiently reliable basis for offering an opinion about the rate
    at which usable fingerprints appear on examined firearms.
    - 8 -
    This   aspect   of   Tavares's       challenge      focuses     on    the
    alleged inadequacies of the compilation of data upon which Auclair
    drew in reaching his opinion about the 16% rate of usable prints
    recovered    from    examined     firearms.         The   last     step    in     that
    compilation was taken by an intern (not working under Auclair's
    supervision), and Auclair did not profess to know what procedures
    the intern had followed in compiling and tabulating the data.
    Although   Auclair     was     not     aware     of    the    specific
    procedures used to compile and tabulate the data that went into
    the intern's report, he made clear that the report was neither an
    ad hoc nor an informal production.                Rather, the report was the
    latest iteration in ordinary course of a type of statistical
    compilation that the Unit had periodically produced on earlier
    occasions.      These past reports were kept by the Unit in the
    ordinary course of its operations and were based on data that the
    Unit had collected and maintained in spreadsheets over a number of
    years.      These   spreadsheets     had    been    prepared       by    Unit   staff
    (including     individuals        with     responsibility          for    technical
    information within the Unit).            The district court did not abuse
    its discretion in finding that Auclair, given his position and
    expertise, was entitled to rely on these spreadsheets.                    See United
    States v. Corey, 
    207 F.3d 84
    , 89 (1st Cir. 2000) (approving
    expert's    reliance    on   "materials      maintained     at     ATF    'research
    libraries,' which contained information on approximately five
    - 9 -
    thousand different firearms"); cf. United States v. Smith, 
    566 F.3d 410
    , 412 (4th Cir. 2009) (upholding admission of ATF agent's
    testimony that relied on "an ATF computerized database that had
    been compiled 'over many, many years as agents have done this
    practice'" in response to a challenge under the best evidence
    rule); Clausen v. M/V New Carissa, 
    339 F.3d 1049
    , 1059-61 (9th
    Cir. 2003) (upholding expert testimony that relied on history and
    reports created by others, even where there was no supported peer-
    reviewed literature).   The intern's report merely updated these
    spreadsheets and tabulated the results, and it was within the
    court's discretion to find that Auclair could reasonably rely on
    that report as well.
    What is more, Auclair testified that the percentage
    identified in the report for the Unit as a whole was "generally
    consistent" with his own long experience and that the scientific
    publications he had consulted did not affect this assessment. This
    testimony provided a basis for concluding that the department's
    report was materially reliable.    It also provided an independent
    basis for the basic point being made:      it was by no means unusual
    to find no usable prints on a gun.    On that point, it could have
    hardly made any difference whether the percentage of guns found to
    have usable prints was exactly 16% or "generally" 16%.        All in
    all, we think that it was within the district court's discretion
    - 10 -
    to accept Auclair's determination that the updated Unit statistics
    were reliable.
    We likewise reject the defendant's related argument that
    Auclair's testimony lacked a proper foundation because he had not
    performed or supervised the work that produced the compilation.
    An expert may rely on information not itself admitted into evidence
    when forming an opinion.     See Jones ex rel. United States v. Mass.
    Gen. Hosp., 
    780 F.3d 479
    , 494 n.8 (1st Cir. 2015).          So, too, an
    expert   may   rely   on   information   that   is   not   independently
    admissible.      See 
    Corey, 207 F.3d at 89
    .          Nor is there any
    requirement that the information relied on by an expert must have
    been compiled by him or under his supervision.             See Crowe v.
    Marchand, 
    506 F.3d 13
    , 18 (1st Cir. 2007).             And though "the
    entirety of [an expert's] testimony cannot be the mere repetition
    of 'the out-of-court statements of others,'" United States v. Luna,
    
    649 F.3d 91
    , 105 (1st Cir. 2011) (quoting United States v. Cormier,
    
    468 F.3d 63
    , 73 (1st Cir. 2006)), that was not the case here:
    Auclair's reliance on the compilation represented only a small
    fraction of his testimony on the subject of unusable prints and
    was corroborated by his familiarity with past calculations by the
    Unit and his own experience.
    Tavares's embrace of our decision in United States v.
    Giambro, 
    544 F.3d 26
    (1st Cir. 2008), does not advance his cause.
    There, the trial court found that the basis for the expert's
    - 11 -
    testimony was "purely anecdotal," and was otherwise unreliable.
    
    Id. at 33.
      Our affirmance of that finding as not an abuse of
    discretion simply does not mean that it was an abuse of discretion
    to admit Auclair's testimony that rested in its material force on
    several independent, non-anecdotal grounds.
    To say more on this point would be to paint the lily.
    In the circumstances here, we think that any question about the
    factual underpinnings of Auclair's opinion goes to its weight, not
    to its admissibility. See Milward v. Acuity Specialty Prods. Grp.,
    Inc., 
    639 F.3d 11
    , 22 (1st Cir. 2011).    So, too, deciding whether
    the data were of a type that Auclair could reasonably rely upon
    under Federal Rule of Civil Procedure 703 was well within the trial
    court's discretion.   See 
    Corey, 207 F.3d at 92
    .
    The defendant's challenge to the relevance of Auclair's
    testimony is equally unavailing.    "Evidence is relevant if:   (a)
    it has any tendency to make a fact more or less probable than it
    would be without the evidence; and (b) the fact is of consequence
    in determining the action."   Fed. R. Evid. 401.   In this instance,
    we think that evidence reflecting the overall rate at which usable
    fingerprints are recovered from firearms was plainly relevant and
    likely helpful to the jury in determining what significance, if
    any, should be accorded to the absence of fingerprints on the
    firearm found at 71 Clarkson Street.   Surely, such evidence had a
    tendency to make a fact of consequence more probable: it suggested
    - 12 -
    that the absence of usable prints did not mean, ipso facto, that
    the weapon was never in the defendant's hands, or that the police
    work was shoddy.   See, e.g., United States v. Burdeau, 
    168 F.3d 352
    , 356–57 (9th Cir. 1999).      Seen in this light, the evidence
    "assisted the jury in understanding that . . . certain objects are
    not particularly conducive to finding prints."     United States v.
    Glover, 
    479 F.3d 511
    , 518 (7th Cir. 2007).         Absent Auclair's
    testimony, "the jury may not have understood how [the defendant]
    could have possessed the weapon without leaving prints."    
    Id. In an
    effort to deflect the force of this reasoning,
    Tavares points out that the 16% figure did not distinguish between
    firearms that were subjected to the so-called "fuming" process
    before they were sent to the lab (like the firearm in this case)
    and those that were not.2   This omission, Tavares submits, rendered
    the testimony too general to be relevant.
    This argument is futile.   There is simply no requirement
    that statistics must in all instances separately account for every
    potentially significant variable in order even to be relevant.
    See Morgan v. United Parcel Serv. of Am., Inc., 
    380 F.3d 459
    , 468-
    69 (8th Cir. 2004).   That is true of the "fuming" variable here.
    2 As explained by Auclair, "fuming" is the process in which a
    firearm is placed in a chamber filled with a heated glue substance.
    The glue then adheres to the moisture in the fingerprint, hardens
    the moisture, and turns the fingerprint white, rendering the print
    visible and less likely to be rubbed away.
    - 13 -
    The defendant had the right--which he exercised--to cross-examine
    Auclair about the chances that the recovery percentage might differ
    materially in cases in which fuming was performed earlier.                     No
    more was exigible: after all, district courts have "broad latitude
    . . . with respect to the determination of the admissibility of
    expert testimony," Crowe, 506 F.3d at 18--and the limits of that
    broad discretion were not exceeded here.
    Tavares has a fallback position.         He contends that the
    challenged testimony, even if relevant, ought to have been excluded
    under   Federal     Rule    of   Evidence   403.    Rule     403   provides,   in
    pertinent part, that "[t]he court may exclude relevant evidence if
    its probative value is substantially outweighed by a danger of .
    . . unfair prejudice, confusing the issues, misleading the jury,"
    or the like.        Fed. R. Evid. 403.        The rule is addressed to the
    district court's informed discretion and its due administration
    recognizes that "[t]his balancing is best performed by the trial
    judge, who has an intimate familiarity with the ebb and flow of
    the case and with its nuances."             United States v. Raymond, 
    697 F.3d 32
    ,    38    (1st    Cir.    2012).        "[O]nly    rarely--and      in
    extraordinarily compelling circumstances--will we, from the vista
    of a cold appellate record, reverse a district court's on-the-spot
    judgment concerning the relative weighing of probative value and
    unfair effect."       
    Id. (quoting Freeman
    v. Package Mach. Co., 
    865 F.2d 1331
    , 1340 (1st Cir. 1988)).
    - 14 -
    Under this generous prescription, the district court's
    admission of the challenged testimony cannot be faulted.                                As we
    have      already    explained,           the    evidence         was    plainly    relevant.
    Tavares, in turn, points to no prejudice that was so substantial
    as   to    compel      exclusion.          To        be   sure,   Auclair's       opinion     was
    prejudicial in the sense that it aided the government's theory of
    the case and diminished the force of Tavares's theory of the case.
    But Rule 403 guards only against unfair prejudice, see United
    States v. Benedetti, 
    433 F.3d 111
    , 118 (1st Cir. 2005), and the
    probative       value         of   this    evidence,          though      modest,     was     not
    substantially        outweighed           by    any       unfairly      prejudicial    effect.
    Hence, there was no abuse of discretion in admitting that evidence.
    B.     Classification of Prior Offenses as "Crimes of Violence"
    Under      §    2K2.1(a)         of    the     United     States     Sentencing
    Guidelines, Tavares's prior criminal record played a substantial
    role in setting his base offense level and Guidelines sentencing
    range. Pursuant to § 2K2.1(a)(4), his base offense level increased
    from      12   to   20,   and--in         Tavares's         case--his      sentencing       range
    increased from 37–46 months to 84–105 months, if he committed the
    subject offense "subsequent to sustaining one felony conviction of
    either a crime of violence or a controlled substance offense."
    U.S.S.G. § 2K2.1(a)(4)(A).                 Under § 2K2.1(a)(2), his base offense
    level increased by an additional four levels, and--in Tavares's
    case--his sentencing range increased from 84–105 months to 120–
    - 15 -
    150 months, if he committed the subject offense subsequent to
    sustaining two such convictions.3
    Over Tavares's objection, the district court found that
    both of these enhancements were proper and assigned Tavares a base
    offense level of 24 under these provisions. The court also adopted
    the PSR's two-level enhancement because the firearm had been
    stolen, U.S.S.G. § 2K2.1(b)(4)(A), resulting in a total offense
    level of 26. In adopting the base offense level of 24, the district
    court relied on the fact that Tavares had previously been convicted
    of two offenses in Massachusetts state court:     Resisting Arrest
    and Assault and Battery with a Dangerous Weapon ("ABDW").      The
    parties agree that neither offense is a controlled substance
    offense.   We must therefore determine whether the district court
    properly categorized each of these state court offenses as a "crime
    of violence" under the Guidelines.   See U.S.S.G. § 4B1.2(a); see
    also 
    id. § 2K2.1,
    cmt. n.1 (adopting definition of "crime of
    violence" in § 4B1.2(a)).
    As relevant here, at the time of Tavares's sentencing,
    the term "crime of violence" was defined as
    any offense under federal or state       law,
    punishable   by  imprisonment for a      term
    exceeding one year, that--
    3 Effectively, the actual sentencing range can only increase to
    120 months because his conviction under 18 U.S.C. § 922(g)(1)
    carries a maximum term of imprisonment of ten years.
    - 16 -
    (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 involves conduct that presents
    a serious potential risk of physical
    injury to another.
    U.S.S.G. § 4B1.2(a) (as amended Nov. 1, 2009).4              Neither party
    maintains that Tavares's Resisting Arrest and ABDW offenses fall
    within any of the enumerated crimes of subsection (2). The parties
    further agree that Johnson v. United States (Johnson II), 
    135 S. Ct. 2551
    (2015), should lead us to deem unconstitutionally vague
    the final clause of subsection (2) (commonly referred to as the
    "residual" clause).     See 
    id. at 2560,
    2563; see also, e.g., United
    States v. Hurlburt, 
    835 F.3d 715
    , 725 (7th Cir. 2016) (collecting
    cases   applying    Johnson   II   to   §   4B1.2(a));   United   States   v.
    Calabretta, 
    831 F.3d 128
    , 137–38 (3d Cir. 2016) (reaching same
    conclusion).     But see Beckles v. United States, 
    616 F. App'x 415
    ,
    415–16 (11th Cir. 2015), cert. granted, 
    136 S. Ct. 2510
    (2016)
    (holding Johnson II does not apply to crimes listed as crimes of
    violence in the commentary to § 4B1.2); United States v. Matchett,
    
    802 F.3d 1185
    , 1196 (11th Cir. 2015) (holding that the sentencing
    guidelines cannot be unconstitutionally vague).              We therefore
    4 Section 4B1.2(a)(2) was subsequently amended on July 13, 2016 to
    alter subsection (2). U.S.S.G. § 4B1.2(a)(2) (as amended July 13,
    2016).
    - 17 -
    proceed to analyze whether the prior offenses at issue qualify as
    crimes of violence under subsection (1) of § 4B1.2(a), commonly
    referred to as the "force" clause.
    1.   Resisting Arrest
    The Massachusetts offense of Resisting Arrest is defined
    as
    knowingly prevent[ing] or attempt[ing] to
    prevent a police officer, acting under color
    of his official authority, from effecting an
    arrest of the actor or another, by:
    (1)    using or threatening to use physical
    force or violence against the police
    officer or another; or
    (2)    using any other means which creates a
    substantial risk of causing bodily injury
    to such police officer or another.
    Mass. Gen. Laws ch. 268, § 32B(a).5
    The parties agree that the version of this offense set
    forth in subsection (2) can no longer be considered to be a "crime
    of violence" under § 4B1.2(a)(2) of the Guidelines in the wake of
    Johnson II.     The government argues, instead, that the version of
    Resisting Arrest described in subsection (1) is a crime of violence
    under the force clause according to our existing case law, United
    States v. Almenas, 
    553 F.3d 27
    , 32–33 (1st Cir. 2009), and that
    subsection (2) is divisible from subsection (1) within the meaning
    5 Tavares was convicted of resisting arrest in 2008.   The statutory
    language has not changed since then.
    - 18 -
    of Descamps v. United States, 
    133 S. Ct. 2276
    , 2284 (2013).                    We
    should therefore remand this case, says the government, so that
    the   district    court    may   consider    whether    documents      that   the
    government supplies as permitted by Shepard v. United States, 
    544 U.S. 13
    , 26 (2005)6 establish that the version of Resisting Arrest
    for which Tavares stood convicted was the subsection (1) version
    ("using or threatening to use physical force or violence against
    the   police     officer   or    another,"   Mass.     Gen.    Laws    ch.    268,
    § 32B(a)(1)), rather than subsection (2).
    Tavares does not dispute that the two versions of the
    Massachusetts       Resisting      Arrest     offense         set     forth     in
    subsections (1) and (2) are divisible under Descamps.                   Nor does
    Tavares disagree that remand for consideration of any Shepard
    documents would be appropriate if the subsection (1) version of
    the offense is a crime of violence.          Instead, Tavares argues that
    the subsection (1) version of the Resisting Arrest offense itself
    fails to qualify categorically as a crime of violence.
    In making this argument, Tavares correctly concedes that
    we have previously held precisely to the contrary; that is, that
    the subsection (1) version of the Massachusetts Resisting Arrest
    offense is a crime of violence under the force clause.                See United
    6 Shepard documents include documents "from the convicting court,
    such as charging documents, plea agreements, plea colloquies, and
    jury instructions." United States v. Serrano-Mercado, 
    784 F.3d 838
    , 843 (1st Cir. 2015).
    - 19 -
    States v. Weekes, 
    611 F.3d 68
    , 72–73 (1st Cir. 2010), cert. denied
    
    564 U.S. 1021
      (2011);   
    Almenas, 553 F.3d at 33
    .      Tavares
    nevertheless points out that these prior opinions did not consider
    the impact of Johnson v. United States (Johnson I), 
    559 U.S. 133
    (2010), which held that the term "physical force" under the force
    clause of the Armed Career Criminal Act ("ACCA"), 18 U.S.C.
    §   924(e)(2)(B)(i),    requires    "violent    force,"     meaning   "force
    capable of causing physical pain or injury to another person."
    Johnson 
    I, 559 U.S. at 140
    .          That holding, the parties do not
    dispute, also applies to the identical phrase at issue here under
    § 4B1.2 of the Guidelines.         See, e.g., United States v. Castro-
    Vazquez, 
    802 F.3d 28
    , 37–38 (1st Cir. 2015); United States v.
    Carrigan, 
    724 F.3d 39
    , 50 (1st Cir. 2013).        Because subsection (1)
    requires "physical force or violence," reasons Tavares, we should
    hold that it does not necessarily require "violent force," and
    hence the offense described in subsection (1) fails to qualify as
    a crime of violence under Johnson I.
    Although we are generally bound by prior panel decisions
    on point, we may depart from circuit precedent if the prior holding
    is "contradicted by controlling authority,
    subsequently announced (say, a decision of the
    authoring court en banc, a Supreme Court
    opinion directly on point, or a legislative
    overruling)," or in "those relatively rare
    instances in which authority that postdates
    the original decision, although not directly
    controlling, nevertheless offers a sound
    reason for believing that the former panel, in
    - 20 -
    light of fresh developments, would change its
    collective mind."
    United States v. Pires, 
    642 F.3d 1
    , 9 (1st Cir. 2011) (citations
    omitted).    It is also true that we decided Almenas before Johnson
    I construed "physical force" as used in the ACCA to require
    "violent force."     Almenas, however, did not rest on the assumption
    that physical force meant something other than violent force.          To
    the contrary, in addressing the defendant's argument that some
    conduct that fell under both subsections of the Resisting Arrest
    statute was non-violent, we described that conduct (stiffening
    one's arm to avoid being handcuffed) as something that could not
    be characterized as "non-violent."        
    Almenas, 553 F.3d at 35
    .     No
    controlling authority issued after Almenas and Weekes contradicts
    our holdings in those cases.        So Tavares must argue that post-
    dated authority that is not directly controlling "nevertheless
    offers a sound reason" for concluding that we would have reached
    a different result had we known what we know now.       
    Pires, 642 F.3d at 9
    .
    Tavares makes a plausible point that one might read
    "physical force or violence" in the Resisting Arrest statute as
    suggesting    that   "physical   force"   means   something   other   than
    violence.     That point, though, was as valid when Almenas was
    decided as it is today.     Moreover, Johnson I itself construed the
    term "physical force" as used in the ACCA to mean "violent force."
    We also see nothing in the Massachusetts case law to which Tavares
    - 21 -
    points indicating that the element of "physical force or violence"
    is satisfied by a degree of physical force that would not equal or
    exceed the ACCA's "physical force."              In Commonwealth v. Katykhin,
    
    794 N.E.2d 1291
    (Mass. App. Ct. 2003), the defendant refused to
    get into a police cruiser, stood "rigid, upright, almost like a
    plank of wood," and "began to pull away [from the police officer],
    starting a tug of war."           
    Id. at 1292.
           In Commonwealth v. Joyce,
    
    998 N.E.2d 1038
    (Mass. App. Ct. 2013), the defendant was "shouting
    and struggling to pull his arms forward to maintain a fighting
    stance with [a third party]" while an officer placed him under
    arrest.     
    Id. at 1044.
        He then refused to move his feet as two
    officers    tried    to   bring    him    to    the   police      cruiser   "pushing
    backwards    and    straining     to     turn    so   that   he    could    shout   at
    bystanders."       
    Id. at 1041,
    1044.          In Commonwealth v. Maylott, 
    841 N.E.2d 717
    (Mass. App. Ct. 2006), the defendant was "moving his
    arms, flailing as he was yelling and screaming" when the officers
    tried to handcuff him.       
    Id. at 718.
            When one officer took hold of
    his right hand, he stiffened his arm and refused to turn around or
    put his hands behind his back.            
    Id. It certainly
    seems reasonable to view the foregoing
    conduct as involving in each instance a use or threatened use of
    force sufficient to cause pain or injury so as to qualify under
    the force clause as construed in Johnson I.                  Whether we would so
    conclude in the absence of binding precedent, we need not decide.
    - 22 -
    Rather, we need only decide--and do decide--that this appeal does
    not present one of those rare occasions in which we might set aside
    controlling circuit precedent.
    That leaves only the question whether the government
    should have the opportunity on remand to supplement the record
    with Shepard documents, assuming such documents exist and would
    pin Tavares's conviction firmly under Massachusetts Resisting
    Arrest subsection (1), rather than (2).     Tavares does not argue
    that the government should not have such an opportunity.     Here,
    importantly, the record was sufficient to sustain the government's
    position at the time of sentencing without any need to present
    Shepard documents, and we remand for reconsideration of that
    sentence only because the controlling law on the residual clause
    thereafter changed.   Under such circumstances, supplementation of
    the record for sentencing on remand is appropriate.
    2.   ABDW
    Chapter 265, § 15A(b) of Massachusetts General Laws sets
    forth the maximum term of incarceration and fine that may be
    imposed on a person "[w]ho[] commits an assault and battery upon
    another by means of a dangerous weapon."   Mass. Gen. Laws ch. 265,
    § 15A(b).7 The substantive definition of ABDW, in turn, is supplied
    by case law applying the crime's common law definition.        See
    7 Tavares was convicted of ABDW in 2009. The relevant portion of
    the statutory language has not changed since then.
    - 23 -
    Commonwealth       v.    Porro,   
    939 N.E.2d 1157
    ,   1162    (Mass.   2010);
    Commonwealth v. Burno, 
    487 N.E.2d 1366
    , 1368-69 (Mass. 1986).                     In
    Burno, the Supreme Judicial Court of Massachusetts ("SJC") applied
    the common law definition of simple assault and battery to describe
    "two separate aspects to the crime" of 
    ABDW. 487 N.E.2d at 1368
    .
    These "separate aspects" both require the use of a dangerous weapon
    and are described as follows:
    [(1)] "the intentional and unjustified use of
    force upon the person of another,
    however slight," or
    [(2)] the intentional commission of a wanton
    or reckless act . . . causing physical
    or bodily injury to another.
    
    Id. at 1368–69
    (citations omitted).              For ease of reference given
    the numerous sections and subsections described in the opinion, we
    refer to these two forms of the offense as Massachusetts ABDW
    sections (1) and (2).
    Tavares makes two principal arguments in challenging the
    district court's classification of this offense as a "crime of
    violence" under § 4B1.2(a)(1) of the Guidelines.                    Relying on this
    court's opinion in United States v. Fish, 
    758 F.3d 1
    (1st Cir.
    2014), he argues that ABDW under Massachusetts law is categorically
    not   a   "crime    of    violence"     under    §    4B1.2(a)(1)      because   (1)
    Massachusetts ABDW section (1)--"the intentional and unjustified
    use of force upon the person of another, however slight"--may be
    committed without employing the necessary "violent force" required
    - 24 -
    by   Johnson   I,   and    (2)    Massachusetts         ABDW    section      (2)--"the
    intentional commission of a wanton or reckless act . . . causing
    physical or bodily injury to another"--may be committed with a
    reckless, as opposed to an intentional, mens rea.                       Tavares also
    argues that, if he is correct that even one of these versions of
    ABDW does not qualify as a crime of violence, he must then prevail
    because    Massachusetts        ABDW    is    not    elementally      divisible   into
    multiple    offenses      and    thus    is    not    subject    to    the    modified
    categorical approach aimed at determining which version of the
    offense was the version for which he was previously convicted.
    See generally 
    Descamps, 133 S. Ct. at 2281-82
    ; United States v.
    Serrano-Mercado, 
    784 F.3d 838
    , 843 (1st Cir. 2015), petition for
    cert. docketed, No. 16-0237 (Aug. 24, 2016); accord Mathis v.
    United States, 
    136 S. Ct. 2243
    , 2248–49 (2016).
    In Fish, we did indeed observe that the government, "with
    good reason," declined to argue that Massachusetts ABDW section
    (1) qualifies as a crime of violence under the force clause of 18
    U.S.C. § 16(a), which is substantially identical to the force
    clause here, U.S.S.G. § 4B1.2(a)(1).                  
    Fish, 758 F.3d at 9
    .        The
    reason, we observed, was that "ABDW may be accomplished by a mere
    'touching, however slight,'" 
    id. (quoting United
    States v. Hart,
    
    674 F.3d 33
    , 42 (1st Cir. 2012)), and therefore did not involve
    the use of physical force, 
    id. - 25
    -
    Nevertheless, in United States v. Whindleton, 
    797 F.3d 105
    (1st Cir. 2015), cert. dismissed, No. 15-9653, 
    2016 WL 3199031
    (Aug. 19, 2016), and cert. denied, No. 16-5101, 
    2016 WL 3633306
    (Oct. 3, 2016), the government advanced the argument it eschewed
    in Fish, and we turned our focus from the ACCA's "use . . . of
    physical force" to its "attempted . . . or threatened use of
    physical force" criterion, finding that a mere touching with a
    dangerous weapon constituted an attempted or threatened use of
    physical force.   
    Id. at 113–16;
    see also United States v. Hudson,
    
    823 F.3d 11
    , 16 (1st Cir. 2016) (reaffirming Whindleton).    We have
    extended the holding in Whindleton from the force clause of the
    ACCA to the force clause of U.S.S.G. § 4B1.2(a). See United States
    v. Fields, 
    823 F.3d 20
    , 33–35 (1st Cir. 2016). Although Whindleton
    was convicted of assault with a dangerous weapon ("ADW"), Mass.
    Gen. Laws ch. 265, § 15B(b), rather than ABDW like Tavares, ADW is
    a "lesser included offense" of ABDW section (1).     See 
    Porro, 939 N.E.2d at 1165
    –66; Commonwealth v. Appleby, 
    402 N.E.2d 1051
    , 1059
    (Mass. 1980).     Therefore, no more "force"--whether attempted,
    threatened, or actually used--could be required for ADW than ABDW
    section (1).    See United States v. Maxwell, 
    823 F.3d 1057
    , 1061
    (7th Cir. 2016) (relying on level of force required by lesser-
    included offense to conclude that a prior state court conviction
    qualified under force clause of § 4B1.2(a)), cert. denied, No. 16-
    6072, 
    2016 WL 5357418
    (Oct. 31, 2016).    Thus, Whindleton's holding
    - 26 -
    means that ABDW section (1) qualifies as a crime of violence under
    the ACCA.     
    Whindleton, 797 F.3d at 113-16
    .    No decision since
    Whindleton calls that conclusion into question or suggests any
    reason why that conclusion should not apply equally to U.S.S.G.
    § 4B1.2(a)(1).     For this reason, and tracking our holding in
    Whindleton rather than the government's concession in Fish, we
    hold that Massachusetts ABDW section (1)--"the intentional and
    unjustified use of force upon the person of another, however
    slight"--constitutes a crime of violence under § 4B1.2(a)(1) of
    the Guidelines.   See 
    Fields, 823 F.3d at 35
    n.12 (not following as
    dicta Fish's observation about Massachusetts ABDW section (1)).
    That holding leaves two questions:    Is Massachusetts
    ABDW section (2)--"the intentional commission of a wanton or
    reckless act . . . causing physical or bodily injury to another"
    --also a crime of violence?   If not, is Massachusetts' definition
    of ABDW divisible?    We address the divisibility question first.
    Ultimately, we conclude that the statute is divisible and remand
    the case to the district court to determine whether Tavares was
    convicted under Massachusetts ABDW section (1) without deciding
    whether Massachusetts ABDW section (2) is also a crime of violence.
    In Fish, this court posited that if Massachusetts had
    set forth the elements of each "aspect" of ABDW by statute, rather
    than in case law, it would read as follows:
    - 27 -
    Assault and Battery with a Dangerous Weapon
    is:
    (1)   The intentional and unjustified touching
    of another by use of a dangerous weapon,
    or,
    (2)   The intentional commission of a wanton or
    reckless act [with a dangerous weapon]
    causing more than transient or trifling
    injury to another.
    
    Fish, 758 F.3d at 15
    .        This offense reads as a divisible statute,
    one   which    "list[s]    elements    in    the   alternative,        and   thereby
    define[s] multiple crimes."          
    Mathis, 136 S. Ct. at 2249
    .             One set
    of elements requires a heightened mens rea--intentional conduct--
    but only slight contact.       
    Burno, 487 N.E.2d at 1368
    –69.              The other
    set     requires    merely   reckless       behavior      but     an   injury     that
    "interfered with the health or comfort of the victim."                       
    Id. at 1370.
       Which set of elements a jury would have to find in order to
    convict would depend upon which form of ABDW the government
    advanced at trial.
    Tavares,    however,    points    us   to    decisions      from     the
    state's     intermediate     appellate      court--the          Appeals   Court    of
    Massachusetts--which hold that jurors need not be unanimous as to
    the form of assault and battery of which it convicts a defendant.

    the court found that the two forms of assault and battery "are
    closely   related    subcategories      of   the   same    crime,"      and    thus
    "[s]pecific    unanimity    is   not   required,    because      they    are   not
    'separate, distinct, and essentially unrelated ways in which the
    same crime can be

    the Criminal Model Jury Instructions for Assault and Battery, while
    laying out the elements for both "Intentional Assault and Battery"
    and "Reckless Assault and Battery," instruct that "[n]o verdict
    slip or specific unanimity instruction [is] required where both
    intentional    and   reckless     assault    and    battery      are    alleged."

    jury with a verdict slip to indicate the theory or theories on
    which the jury bases its verdict and is required, on request, to

    We   first    consider   whether     Mistretta's    holding    is
    relevant to the divisibility inquiry before deciding whether it
    accurately reflects Massachusetts state law.          The precise question
    before us is whether the differing items involved in committing
    each form of the offense--intentional versus reckless mens rea;
    slight contact versus bodily injury--"merely specif[y] diverse
    means of satisfying a single element of a single crime," or
    constitute "elements in the alternative, . . . thereby defin[ing]
    multiple   crimes."      Mathis,    136    S.   Ct.   at   2249.     Whether
    Massachusetts requires that jurors unanimously agree on the form
    of ABDW under which they are convicting a defendant informs this
    analysis because the Supreme Court and this court have repeatedly
    stated that jurors must unanimously find that the government proved

    State law as to what facts a jury must agree upon
    unanimously    plays   a   crucial   role   in   distinguishing   between
    elements and mere factual means.9      See 
    Mathis, 136 S. Ct. at 2250
    ("[The locations listed in the Iowa burglary statute] lay out
    alternative ways of satisfying a single locational element, as the
    Iowa Supreme Court has held:         Each of the terms serves as an
    'alternative method of committing [the] single crime' of burglary,
    9 Before Mathis, the circuits were split on this question. See
    Almanza-Arenas v. Lynch, 
    815 F.3d 469
    , 479–81 (9th Cir. 2016) (en
    banc) (recognizing circuit split).

    so that a jury need not agree on which of the locations was actually
    involved." (quoting State v. Duncan, 
    312 N.W.2d 519
    , 523 (Iowa
    1981))).     Thus, if Mistretta accurately reflects Massachusetts
    state law, it means that Massachusetts ABDW is indivisible.
    We must therefore predict how the SJC would decide
    whether a specific unanimity instruction is required in an ABDW
    prosecution, using Mistretta as a reliable piece of evidence.
    Mistretta applied the standard set forth by the SJC in Santos for
    determining when jury unanimity is required.                      In Santos, the
    defendant claimed that the trial judge had erred by refusing to
    give    a   specific    unanimity       instruction     with      respect    to     the
    indictment charging armed 
    robbery. 797 N.E.2d at 1194
    .            He argued
    that whether he had used force on the victim or had merely placed
    the victim in fear constituted different "theories" of the assault
    element of armed robbery, thus requiring specific unanimity.                        
    Id. at 1196.
        The SJC disagreed and held that a specific unanimity
    instruction was not required.            
    Id. at 1198.
    Santos    reached    this    holding      on   the   basis     of    three
    intermediate conclusions.         First, a specific unanimity instruction
    is only required when there is more than one "theory" of guilt for
    a charged crime, and the alternative "theories" are "substantively
    distinct or dissimilar."          
    Santos, 797 N.E.2d at 1197
    –98.             Second,
    two    "alternate     method[s]    by    which     a   single     element     may    be
    established" that are "closely related" are not substantively
    - 32 -
    distinct or dissimilar.      
    Id. Third, "actual
    force" and "threat of
    force" are closely related factual means of satisfying a single
    element.    
    Id. at 1198.
       The second and third conclusions indicate
    that actual force and threat of force are not substantively
    distinct or dissimilar.      Thus, by the first conclusion, a specific
    unanimity instruction was not required.
    Dictum   in    the    Santos     opinion   clarifies     that,    in
    determining whether two forms of an offense are "substantively
    distinct or dissimilar" theories or "closely related" methods of
    proving the same elements, courts should consider the mens rea
    requirements of the two forms of the offense.                The SJC offered
    manslaughter as an example of a crime that may be proved by two
    different    theories      that     are     "substantively       distinct     or
    dissimilar"--namely,       voluntary       manslaughter    and      involuntary
    manslaughter.    
    Id. at 1197.
          Under Massachusetts law, "voluntary
    manslaughter is an intentional killing, which is mitigated by
    extenuating circumstances,'" Commonwealth v. Squailia, 
    706 N.E.2d 636
    , 642 (Mass. 1999) (emphasis omitted), while "[i]nvoluntary
    manslaughter    is   an   unintentional,      unlawful    killing    caused   by
    wanton or reckless conduct," Commonwealth v. Earle, 
    937 N.E.2d 42
    ,
    48 (Mass. 2010).     The Santos opinion concluded that voluntary and
    involuntary manslaughter were not closely related because of their
    different mens rea 
    requirements. 797 N.E.2d at 1197
    ("[V]oluntary
    and involuntary manslaughter are mutually exclusive--one cannot
    - 33 -
    kill both intentionally and unintentionally at the same time.").
    This conclusion could apply equally to Massachusetts ABDW section
    (1) and Massachusetts ABDW section (2), which, like the two forms
    of manslaughter, differ in that one requires intent while the other
    requires recklessness.        Thus, this dictum from Santos indicates
    that Mistretta was wrongly decided.
    Mistretta, however, also drew support from a later SJC
    opinion, Porro, 
    939 N.E.2d 1157
    , which complicates the analysis.
    Porro addressed the relationship between two different types of
    assault:    attempted    battery      assault     and   threatened    battery
    assault.   The court held that "[a]n assault under a theory of
    attempted battery . . . has elements different from an assault
    under a theory of threatened battery."          
    Id. at 1163.
      The elements
    of attempted battery assault are that "the defendant 'intended to
    commit a battery, took some overt step toward accomplishing that
    intended battery, and came reasonably close to doing so.'"                
    Id. (citation omitted).
        The elements of threatened battery assault
    are "that the defendant engaged in conduct that a reasonable person
    would recognize to be threatening, that the defendant intended to
    place the victim in fear of an imminent battery, and that the
    victim perceived the threat."        
    Id. Although these
       two   forms   of   assault   have     different
    elements, Porro contains a statement (itself also dictum) that a
    specific unanimity instruction is not required in prosecutions for
    - 34 -
    assault. 
    Id. at 1165–66.
    This statement, if adopted, would extend
    Santos's holding as to the assault element of robbery to the
    substantive crime of assault:
    Because attempted battery and threatened
    battery "are closely related," we do not
    require that a jury be unanimous as to which
    theory of assault forms the basis for their
    verdict; a jury may find a defendant guilty of
    assault if some jurors find the defendant
    committed an attempted battery (because they
    are convinced the defendant intended to strike
    the victim and missed) and the remainder find
    that he committed a threatened battery
    (because they are convinced that the defendant
    intended to frighten the victim by threatening
    an assault).
    
    Porro, 939 N.E.2d at 1165
    (quoting 
    Santos, 797 N.E.2d at 1197
    );
    see also Commonwealth v. Arias, 
    939 N.E.2d 1169
    , 1173–74, 1173 n.2
    (Mass. App. Ct. 2010).
    Porro's dictum is in tension with United States Supreme
    Court precedent.   Under a literal reading, Porro states that the
    two forms of assault have different elements and that a jury may
    convict a defendant of assault without agreeing unanimously about
    which elements of the crime were satisfied.        Such a holding would
    contradict the definition of "element" as it is used by the Supreme
    Court.   See, e.g., 
    Mathis, 136 S. Ct. at 2250
    .         While we could
    reject   the   SJC's   conclusion    about   the   specific   unanimity
    requirement for assault as dictum, we note that it has been
    incorporated into the model jury instructions for assault.         See
    Massachusetts Criminal Model Jury Instructions for Use in the
    - 35 -
    District Court, Instruction 6.120, at 4 n.9 (2009 ed.), available
    at                       http://www.mass.gov/courts/docs/courts-and-
    judges/courts/district-court/jury-instructions-criminal/6000-
    9999/6120-assault.pdf.     Thus, we conclude that the Porro opinion
    uses the word "element" differently than the Supreme Court.     Under
    the Supreme Court's usage, Porro's dictum that a specific unanimity
    instruction is not required in prosecutions for assault implies
    that the two forms of assault are alternative means of proving the
    same elements.10
    Porro is also in tension with the dictum from Santos
    from which we concluded that Mistretta was wrongly decided.      Like
    the example of voluntary and involuntary manslaughter, the two
    forms of assault considered in Porro have different mens rea
    requirements.      Attempted battery requires an intent to commit a
    battery, while threatened battery requires an intent to place the
    victim in fear of an imminent battery.      
    Porro, 939 N.E.2d at 1163
    .
    These two mens rea requirements are more closely related than
    intent and recklessness, however.      While "one cannot kill both
    intentionally and unintentionally at the same time," 
    Santos, 797 N.E.2d at 1197
    , one could easily intend both to commit a battery
    10 This interpretation of Porro is consistent with the central
    holding of that opinion, which is that both forms of assault are
    generally lesser included offenses of assault and battery, even
    though the "elements" of assault and battery and threatened battery
    do not overlap in the way that is usually required. See 
    Porro, 939 N.E.2d at 1165
    .
    - 36 -
    and to place a victim in fear of an imminent battery.                 Therefore,
    Porro does not alter the conclusion we reached above.                 We predict
    that the SJC would not follow Mistretta.
    This conclusion is compatible with the language the
    United States Supreme Court has used to distinguish elements from
    mere facts.       Whether one commits ABDW with an intentional or
    reckless mens rea carries with it an important legal consequence:
    it   changes   the    required       result   of   the   battery   needed   for   a
    conviction.     If the actor intentionally uses force upon another,
    no injury must be proven, but if the actor intends only to commit
    conduct that is reckless, physical or bodily injury must be proven.
    
    Burno, 487 N.E.2d at 1368
    –69.           The differences in the two forms of
    Massachusetts ABDW--intentional versus reckless mens rea, slight
    touching versus bodily injury--are substantively distinct and
    therefore constitute alternative elements, rather than different
    factual means of establishing a single set of elements.                       See
    Mathis, 136 S Ct. at 2248 ("Facts . . . . are 'circumstance[s]' or
    'event[s]' having no 'legal effect [or] consequence.'" (quoting
    Black's Law Dictionary 709 (10th ed. 2014))).                  Accordingly, we
    find that the crime of Massachusetts ABDW is divisible.
    Of course, given our finding that Massachusetts ABDW
    section (1) is a crime of violence, our conclusion that ABDW is
    divisible      only   makes      a    difference     if    Massachusetts     ABDW
    section (2)--the reckless version of ABDW--is not a crime of
    - 37 -
    violence.    Prior to the Supreme Court's recent decision in Voisine
    v. United States, 
    136 S. Ct. 2272
    (2016), precedent directly
    dictated that the reckless, unintentional causing of injury, such
    as unintentionally hitting a pedestrian while driving recklessly,
    was not a crime of violence under 18 U.S.C. § 16(b).11              See 
    Fish, 758 F.3d at 10
    –14.      Our holding in Fish was based on the reasoning
    of Leocal v. Ashcroft, 
    543 U.S. 1
    (2004), which interpreted the
    phrase "use . . . physical force against the person or property of
    another" to require "active 
    employment." 543 U.S. at 9
    ; see also
    
    Fish, 758 F.3d at 9
    -10. Such reasoning would seem to apply equally
    to the pertinent Guidelines definition of a crime of violence at
    issue here.      Thus, Fish would dictate that a conviction for the
    reckless version of ABDW is not a crime of violence under U.S.S.G.
    § 4B1.2(a)(1). Voisine, though, calls into question the continuing
    validity of Fish, as well as the similar and analogous holdings of
    at least ten other circuits.          See 
    Fish, 758 F.3d at 9
    -10, 10 n.4
    (listing cases).
    In     Voisine,   the   Supreme   Court   held   that   18    U.S.C.
    §    922(g)(9)'s    prohibition     against   gun   possession   for     persons
    convicted "of a misdemeanor crime of violence" extended to persons
    11Section 16(b) provides that "any . . . offense that is a felony
    and that, by its nature, involves a substantial risk that physical
    force against the person or property of another may be used in the
    course of committing the offense" is a crime of violence.       18
    U.S.C. § 16(b).
    - 38 -
    convicted of such an offense even under a reckless theory of mens
    
    rea. 136 S. Ct. at 2282
    .      It reasoned that the word "use" in
    18 U.S.C. § 921(a)(33)(A), which defines the term "misdemeanor
    crime of domestic violence" as including a misdemeanor that "has,
    as an element, the use or attempted use of physical force,"
    encompasses "an act of force carried out in conscious disregard of
    its substantial risk of causing harm," i.e., reckless 
    conduct. 136 S. Ct. at 2279
    .      The government contends that this reasoning
    applies equally in interpreting the word "use" in § 4B1.2(a)(1) of
    the Guidelines.
    That    this   contention    is   correct,    however,   is   not
    entirely clear. As Tavares points out, Voisine itself specifically
    left open the question whether reckless conduct is encompassed in
    the similar statutory language found in 18 U.S.C. § 16.                 See
    
    Voisine, 136 S. Ct. at 2280
    n.4.       And in reaching its conclusion,
    the Court also relied upon the history and purpose of § 922(g)(9),
    explaining   that   a    contrary   finding    "would   have   undermined
    Congress's aim," 
    id. at 2281,
    to prohibit domestic abusers from
    possessing firearms in light of the fact that "a significant
    majority of jurisdictions . . . defined such misdemeanor offenses
    to include the reckless infliction of bodily harm," 
    id. at 2280.
    Indeed, Voisine recognizes in a footnote that "[c]ourts have
    sometimes given [§ 921(a)(33)(A) and § 16] divergent readings in
    light of differences in their contexts and purposes, and we do not
    - 39 -
    foreclose that possibility with respect to their required mental
    states."      
    Id. at 2280
    n.4.             Further muddying the waters is the
    different statutory language used in each statute: § 921(a)(33)(A)
    refers     only      to    the     "use    of    physical     force,"      18   U.S.C.
    §   921(a)(33)(A)(ii),           whereas    §   4B1.2(a)(1)    of    the    Guidelines
    refers   to    the    "use    of    physical     force   against     the    person   of
    another," U.S.S.G. § 4B1.2(a)(1) (emphasis added).                         See 
    Leocal, 543 U.S. at 9
    ("Whether or not the word 'use' alone supplies a
    mens rea element, the parties' primary focus on that word is too
    narrow . . . .            The critical aspect of § 16(a) [in determining
    that it excludes negligent or accidental conduct] is that a crime
    of violence is one involving the 'use . . . of physical force
    against the person or property of another.'").                      But see 
    Voisine, 136 S. Ct. at 2279
    (stating that the quoted reasoning from Leocal
    "fully accords with our analysis here").
    Even a careful reader of this opinion may at this point
    feel lost. We began with a seemingly simple question. Has Tavares
    been convicted of a crime of violence?                    Trying to answer that
    question then led us down several rabbit holes:                     Is Massachusetts
    ABDW a divisible offense under Descamps and Mathis?                          How does
    Massachusetts law define the relationship between the two common
    forms of the offense?               Does Voisine upend the circuits' wide
    consensus that recklessly causing injury is different than using
    force against a person?
    - 40 -
    In a sensible world, Congress and/or the Sentencing
    Commission would have made a list of state and federal laws deemed
    to be crimes of violence that warranted the desired penalties and
    sentencing enhancements.         At its margins, such a list might be
    over- or under-broad.        It would, though, be straightforward.
    Instead of using a simple list, the drafters adopted
    abstract descriptions of the crimes that would appear on such a
    list, employing terms such as "physical force," "use," "injury,"
    and so on.        The result is a Rube Goldberg jurisprudence of
    abstractions piled on top of one another in a manner that renders
    doubtful anyone's confidence in predicting what will pop out at
    the end.      Cf. Almanza-Arenas v. Lynch, 
    815 F.3d 469
    , 483–84 (9th
    Cir. 2015) (en banc) (Owens, J., concurring).
    What pops out matters a great deal.         In Fish, one could
    not know whether certain conduct was lawful or criminal unless one
    knew whether a prior crime was a crime of violence.             Here, Tavares
    could   not    know--within    years--the      guidance   applicable   to    his
    sentencing.       Nor could one get confident answers by asking a
    lawyer--or even a judge. So what do we do here? For three reasons,
    we stop short of finally deciding now whether a conviction under
    the reckless version of ABDW qualifies as a crime of violence.
    First,   the   Supreme   Court    has   granted   certiorari   in
    Beckles v. United States, 
    616 F. App'x 415
    (11th Cir. 2015), cert.
    granted, 
    136 S. Ct. 2510
    (2016).            Although the Eleventh Circuit
    - 41 -
    decided that case on the narrow ground that Johnson II did not
    apply to a career offender enhancement based on the Guidelines
    commentary to § 4B1.2, 
    id. at 415–16,
    the petition for certiorari
    raised the much broader question as to whether Johnson II applies
    to the residual clause of § 4B1.2(a)(2).       See Petition for Writ of
    Certiorari at i, Beckles v. United States, No. 15-8544 (U.S. Mar.
    9, 2016), 
    2016 WL 3476563
    .     The Supreme Court granted the petition
    in full, 
    136 S. Ct. 2510
    , 2510, and thus may well answer this
    broader question.      If the Court decides that Johnson II does not
    so apply, then the district court may consider if it can once again
    rely on the residual clause or if the government has forfeited any
    reliance on that clause by conceding the issue on appeal.
    Second, even if Beckles does not put the residual clause
    back in play in this case, it will only be necessary to decide
    whether the reckless version of ABDW is a crime of violence if
    there are no Shepard documents that make clear that Tavares's ABDW
    conviction was for the intentional version of the offense.            As
    Tavares   noted   in   his   supplemental    brief,   the   Massachusetts
    district court criminal model jury instructions, at least prior to
    this year, instructed Massachusetts courts to use a jury verdict
    form for ABDW charges that would plainly reveal which version of
    the offense was the offense of conviction.12 Common sense suggests,
    12 They may still do so for ABDW, though not for assault and
    battery. See note 8, supra.
    - 42 -
    too, that by far the most common version of the offense charged is
    the intentional version.               In sum, whether the reckless version of
    ABDW   is    also       a   crime    of    violence        will   likely       not    make   any
    difference in this case.
    Third, in the event that it does make a difference, the
    parties will be able to brief the issue and the district court--
    for the first time--will be able to consider it.                               We, in turn,
    will then have the benefit of a fully developed record, the
    district court's views, and likely more precedent to consider as
    we and other courts encounter the "recklessness" question in other
    cases in which the answer does make a difference.                               We therefore
    remand      to    the       district      court    to   allow      the     government        the
    opportunity to put forth Shepard documents that clarify whether
    Tavares's ABDW conviction was for the intentional or reckless
    version of the offense.
    CONCLUSION
    We   affirm        Tavares's       conviction,          but    remand       for
    reconsideration of his sentence consistent with this opinion.                                 If
    the district court concludes that either the Resisting Arrest
    conviction or the ABDW conviction did not qualify under the career
    offender guideline, it should vacate and resentence.                                 Otherwise,
    it should vacate and then re-enter the present sentence.
