    APPEAL FROM THE UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF MASSACHUSETTS

    Souter, Associate Justice,*
    and Stahl, Circuit Judge.

    * Hon. David H. Souter, Associate Justice (Ret.) of the
    Supreme Court of the United States, sitting by designation.
    KAYATTA, Circuit Judge.         This case makes its second
    appearance on our docket. The first appeal followed the conviction
    of Foster Starks, Jr. for possessing a firearm in violation of 18
    U.S.C. § 922(g)(1).        We vacated that conviction because the
    district court erred in finding that Starks lacked standing to
    challenge the lawfulness of a traffic stop that led to his arrest
    and the discovery of a gun and ammunition in a car he was driving.
    See United States v. Starks (Starks I), 
    769 F.3d 83
    , 88–90 (1st
    Cir. 2014).     On remand, the district court adjudicated Starks's
    challenge to the traffic stop on its merits, ruling that the stop
    and the resulting search were lawful.            Following a second jury
    trial, Starks was again convicted.         He now asks that we set aside
    this   conviction      because   the     trial   judge,   Starks   claims,
    effectively commented on the credibility of witnesses by telling
    the jurors that the judge had ruled prior to trial that the traffic
    stop was lawful.       Starks also contends that the district court
    erred in determining that he was subject to a 180-month mandatory
    minimum sentence under the Armed Career Criminal Act (ACCA), 18
    U.S.C. § 924(e), on account of three prior convictions for the
    offense   of   armed   robbery   under    Massachusetts   law.     For   the
    following reasons, we affirm Starks's conviction but vacate his
    sentence.
    - 2 -
    I.
    A.
    Starks's challenge to his conviction rests on a jury
    instruction.      Starks does not claim that the instruction in any
    way misstated the law. Rather, he claims that when the trial judge
    told the jury that the judge had already found the police officer's
    stop of Starks to be lawful, the judge effectively commented on
    the   credibility    of   the     two   key     witnesses   at   trial   and   put
    additional facts before the jury that bore on the witnesses'
    credibility.      Judicial comments on the credibility of a witness in
    a criminal trial before a jury are improper.                 See, e.g., United
    States v. Márquez–Pérez, 
    835 F.3d 153
    , 158 (1st Cir. 2016); United
    States v. Ayala-Vazquez, 
    751 F.3d 1
    , 28 (1st Cir. 2014).                 So, too,
    are judicial statements adding information to the record that bears
    on a witness's credibility.         See, e.g., Quercia v. United States,
    
    289 U.S. 466
    , 471–72 (1933); United States v. Cisneros, 
    491 F.2d 1068
    , 1075 (5th Cir. 1974). So we begin our inquiry by determining
    whether the trial court's instruction, in context, could be so
    understood by the jurors.         Cf. United States v. Rivera-Rodríguez,
    
    761 F.3d 105
    , 120–23 (1st Cir. 2014) (reviewing the record to
    determine    if    the    trial    judge's       interventions     created     the
    appearance of bias).       Toward that end, we summarize enough of the
    relevant evidence to allow us to gauge how the jurors might
    - 3 -
    reasonably have construed the instruction and, if necessary, how
    much and to what degree of likelihood prejudice1 would have ensued.
    On May 24, 2009, at around 10:00 or 11:00 P.M., Starks
    pulled       over   in   the   breakdown    lane    on   Route     24   in     Taunton,
    Massachusetts.           He was driving a black Kia Sportage with the
    permission of an acquaintance who had rented the vehicle.                        Jason
    Vital, a Massachusetts state trooper, pulled over behind him, got
    out of his cruiser, and approached Starks's vehicle.                     When Starks
    exited the vehicle, Vital asked him if anything was wrong.                      Starks
    responded that he had just dropped a cigarette.                    Vital testified
    that       Starks   appeared   nervous     during    this      interaction;      Starks
    testified that he was not nervous.                  After Starks retrieved his
    cigarette, he and Vital returned to their respective vehicles and
    pulled back onto Route 24.
    Vital started following Starks.           Vital testified that he
    noticed       Starks     drifting   slightly   into      the    next    lane   without
    signaling on three occasions.            Starks testified, to the contrary,
    that he stayed in his lane and did not drift.                       Vital used his
    1
    The parties disagree about what standard we should apply to
    determine whether reversal is necessary if we conclude that the
    district court commented on the credibility of witnesses. Some of
    our cases on this type of judicial error require serious prejudice,
    see 
    Márquez–Pérez, 835 F.3d at 161
    –62; 
    Rivera-Rodríguez, 761 F.3d at 123
    , while another applies multiple different standards,
    including the "harmless beyond a reasonable doubt" standard, see
    
    Ayala-Vazquez, 751 F.3d at 24-28
    . Because we conclude that the
    trial court's instruction did not comment on the credibility of
    witnesses, we need not resolve this apparent tension.

    computer to check the registration on Starks's car and discovered
    that the car was registered to a rental company and listed as red
    rather than black. At that point, Vital pulled Starks over. Vital
    testified without contradiction that the color discrepancy alone
    justified pulling Starks over.
    Vital   approached   Starks's     driver's-side    window    and
    informed him that the registration indicated that Starks's car was
    red rather than black.2 Starks responded that the car was a rental.
    Vital asked for Starks's license and registration, which Starks
    provided.       On checking the status of Starks's license, Vital
    learned that it had been suspended for failure to pay a ticket.
    He   placed    Starks   under   arrest   for    driving   with   a   suspended
    license.3     Vital testified that after he asked Starks to exit the
    vehicle, Starks's "nervous level had grown exponentially."              Starks
    testified that he was not nervous.          After securing Starks in the
    back seat of the cruiser, Vital requested a tow of the rental car
    pursuant to state police policy.               He then looked through the
    windows of the car with a flashlight.           He saw a white Wal-Mart bag
    containing a box of ammunition in the front passenger's seat.               He
    2There was a discrepancy between Vital's testimony and
    Starks's testimony as to whether Vital mentioned the marked lanes
    violation when he pulled Starks over.
    3Vital also suggested at trial that Starks's failure to
    present a user agreement from the rental car company indicated
    that he was not authorized to drive the vehicle.
    - 5 -
    opened the car door and searched the bag, whereupon he found more
    ammunition and a firearm wrapped in a black bandana.
    Following our decision in Starks I, and prior to trial,
    Starks pressed his motion to suppress the firearm and ammunition,
    arguing that the stop was unconstitutional.      The district court
    rejected this motion after a hearing at which Starks did not
    testify.
    At trial, Starks did not contest that the Wal-Mart bag
    in his car contained a firearm and ammunition.         Instead, his
    defense was that he came into possession of the Wal-Mart bag
    without knowing its contents.4     The key points of his account are
    these:   Starks's son, Dante, had been arrested on May 23 after his
    girlfriend reported to the police that he had assaulted her.      On
    the evening of May 24, Dante called and asked Starks to go to his
    apartment to pick up clothing and documents for court.        Starks
    drove to the apartment and encountered Dante's girlfriend.       She
    agreed to retrieve the clothing and documents while Starks waited
    in the car outside.   She walked out to the car with the Wal-Mart
    bag, which she placed in the front passenger's seat.    Starks drove
    away without looking in the bag.    To support this account, defense
    4 Starks also did not contest that the other elements of 18
    U.S.C. § 922(g) were satisfied. He stipulated that he had been
    convicted of a felony punishable by over one year in prison. He
    did not contradict the government's evidence that the gun and
    ammunition had passed in interstate commerce.
    - 6 -
    counsel asserted that it made no sense for Starks to place a bag
    containing a gun and ammunition in the front passenger's seat of
    the car and to leave it there even after Vital pulled him over.
    The   government   challenged   Starks's   account   in   two
    primary ways.   First, the government pointed out that the Wal-Mart
    bag contained four bottles of prescription pills, all of which
    were prescribed to Starks.   Starks specifically sought the return
    of these pills--along with the clothing and documents--after he
    was booked and released on bail. Second, the government questioned
    whether it was plausible that Starks would trust Dante's girlfriend
    to retrieve Dante's clothing and documents after she had reported
    Dante to the police.    The government suggested that it was far
    more plausible that Starks had gone into Dante's apartment himself
    to retrieve the pills, the clothing, and the documents--and that
    he had taken the gun and ammunition too, so that Dante's estranged
    girlfriend wouldn't turn them over to the police.
    During closing arguments, defense counsel sought to cast
    doubt on aspects of Vital's testimony.    Counsel argued that during
    the first interaction, "[Starks] wasn't nervous.       Trooper Vital
    would have you believe that he was nervous. . . .         He was not
    somebody who was fearful of the police."         Counsel relied on
    Starks's testimony that he had once worked as a truck driver to
    argue that he was not drifting from lane to lane without signaling:
    "[Starks] drives for a living. He knows at that point that there's
    - 7 -
    a trooper that's following behind him. . . .          Somebody who has a
    [commercial driver's] license and who relies on their license,
    doesn't drive in that way and they know how to drive." On rebuttal,
    the   government   argued,   for    the    first   time,   that    Starks's
    nervousness while interacting with Vital was evidence he knew about
    the gun and ammunition on the seat next to him.
    During the final jury charge, the district court gave
    the instruction that Starks now challenges on appeal.             The court
    instructed the jury:
    Legality of the traffic stop. You have
    heard testimony by Trooper Vital and Mr.
    Starks about the circumstances surrounding
    Trooper Vital's stop of the rental car Mr.
    Starks was driving and the reasons for that
    stop.
    To the extent their descriptions of those
    circumstances differed, you may consider such
    testimony like any other testimony. You are
    not called upon, however, to determine the
    legality of the stop.      Before the trial, I
    ruled that the stop was lawful. That was a
    legal determination and you may not question
    my ruling.     However, the evaluation of the
    credibility of Trooper Vital, Mr. Starks, and
    the other witnesses is solely and entirely for
    you to determine, including all facts and
    circumstances about which you heard testimony.
    The district court had previously instructed the jury that the
    judge's "opinion about the evidence in this case, if [he] ha[s]
    one, is totally irrelevant"; that the jury "should not interpret
    anything [the judge] ha[s] said or done during the trial as
    indicating what [he] think[s] about a witness or a piece of
    - 8 -
    evidence or what [he] believe[s] the verdict should be"; and that
    the   jurors   were   "the   sole   judges   of   the   credibility    of    the
    witnesses."
    B.
    The instruction on the legality of the stop, argues
    Starks on appeal, implicitly told the jury that a suppression
    hearing had occurred before trial, that Starks and Vital had given
    conflicting testimony at that hearing, and that the judge had found
    Vital to be more credible. That implicit comment on the respective
    credibility of the two central witnesses, he claims, tilted the
    jury's assessment of which witness spoke credibly at trial on the
    subject of whether Starks was nervous during the stop.                      This
    nervousness, the jury may have reasoned, evidenced his knowledge
    of the gun and ammunition in the Wal-Mart bag.
    The government counters, first, that Starks failed to
    raise this objection when the instruction was given.              We disagree.
    In response to the proposed instruction about the legality of the
    stop, Defense counsel argued specifically that "it's really an
    issue of credibility for the jury" to evaluate the contrasting
    testimonies of Starks and Vital and "[f]or the[] [jury] to be told
    that the stop is lawful . . . would then be taking that question
    of fact away from them."       The trial judge understood Starks to be
    raising this issue, acknowledging "the possibility" that the jury
    might   understand    the    instruction     as   "a    removal   of   certain
    - 9 -
    credibility determinations from them."               The judge proposed adding
    the last sentence of the instruction to resolve Starks's objection,
    but defense counsel was not satisfied and renewed the objection
    after the charge.         It does not matter that defense counsel never
    used the words "due process" when stating the objection.                     Such an
    omission, if one calls it that, is much like not specifically
    mentioning        the     Fourth       Amendment     when         challenging       the
    reasonableness of a search.             In either situation, a trial court
    understands the point being made.                So, we turn to the merits of
    the preserved objection.
    On the merits, we agree with the government that the
    challenged instruction simply cannot carry the meaning Starks
    assigns to it.          The instruction itself provided no hint that the
    court's legal determination turned on an assessment of credibility
    or was the result of a hearing at which Starks and Vital testified.5
    To the contrary, both in its preface and in its conclusion, the
    instruction      distinguished        the   legal   ruling    from      questions   of
    credibility.       Importantly, too, the evidence that the jurors did
    hear       concerning    the   stop    itself    pointed     to    an   obvious     and
    highlighted reason for the court's ruling that did not touch on
    credibility.       Specifically, Vital testified that the car's color
    5
    In fact, the court's legal determination did not turn on an
    assessment of relative credibility, as Starks did not testify at
    the suppression hearing.
    - 10 -
    did not match the color listed on the car's registration and that
    such a discrepancy itself justified the stop.6                 Starks did not
    dispute or challenge either aspect of this testimony.
    In sum, we have on the one hand something of a stretch:
    An   argument   that   lay    jurors    would   read    judicial   credibility
    endorsements into an unadorned statement by the trial judge that
    he found the stop lawful.        On the other hand, we have an explicit
    instruction that it was up to the jury to assess the witnesses'
    credibility, and an explanation for the lawfulness of the stop
    that had nothing to do with the witnesses' credibility.                  All in
    all, we can find no direct or indirect comment on the credibility
    of the witnesses.      And while the instruction did communicate to
    the jury an additional fact not otherwise in evidence--that the
    court had made a legal determination about the stop prior to
    trial--Starks's    only      argument   that    the    trial   judge   erred   by
    communicating this fact is that it implied a comment on the
    witnesses' credibility.7        Having rejected the notion that such an
    implication was conveyed in these circumstances, we find no error.8
    6We express no opinion as to whether Vital's testimony on
    this point correctly stated the law.
    7
    Starks did not adequately brief, and therefore waived, other
    potential bases for challenging the instruction. See United States
    v. Zannino, 
    895 F.2d 1
    , 17 (1st Cir. 1990).
    8A trial court may not always reliably predict how                        an
    instruction of this type might be interpreted in context. In                   the
    event a trial court concludes that such an instruction                          is
    warranted, it might well be better practice simply to give                     the

    II.
    A.
    We turn next to whether the district court properly found
    that Starks had at least "three previous convictions by any
    court   .   .   .   for   a    violent    felony"     under   the    ACCA,    thereby
    triggering      a   mandatory      minimum        sentence    of    fifteen    years'
    imprisonment for violating 18 U.S.C. § 922(g).                       See 18 U.S.C.
    § 924(e)(1).        The ACCA defines a "violent felony," in relevant
    part, as
    any crime punishable by imprisonment for a
    term exceeding one year . . . that--
    (i) has as an element the use, attempted
    use, or threatened use of physical force
    against the person of another; or
    (ii) is burglary, arson, or extortion,
    involves use of explosives, or otherwise
    involves conduct that presents a serious
    potential risk of physical injury to
    another.
    
    Id. § 924(e)(2)(B).
              We refer to clause (i) as the "force clause"
    and understand "physical force" to mean "violent force--that is,
    force capable of causing physical pain or injury to another
    person."     Johnson v. United States (Johnson I), 
    559 U.S. 133
    , 140
    (2010).     Clause (ii) is not at issue here because armed robbery is
    not one of the enumerated offenses in the "enumerated offense
    clause" and the "residual clause"--the clause deeming a violent
    jury an instruction along these lines: "Any challenges to the
    lawfulness of a stop are for me to resolve.  You need not be
    concerned about them."
    - 12 -
    felony any crime that "otherwise involves conduct that presents a
    serious potential risk of physical injury to another"--has been
    declared unconstitutionally vague, see Johnson v. United States
    (Johnson II), 
    135 S. Ct. 2551
    , 2557 (2015).
    At sentencing, the parties contested whether Starks had
    three       prior   convictions    for      "violent   felon[ies]"      within    the
    meaning of the ACCA.            Starks's presentence investigation report
    (PSR) indicated that he had at least three prior convictions for
    armed       robbery    arising    from      separate   occasions,9      one     prior
    conviction for armed robbery while masked, two prior convictions
    for unarmed robbery, and one prior conviction for armed assault
    with intent to rob, all under Massachusetts law. Most of the armed
    and unarmed robbery convictions occurred in 1991.                  The exceptions
    are a conviction for armed robbery while masked in 1996 and a
    conviction for armed robbery in 1998.              Starks did not dispute that
    he had been convicted of the offenses listed in his PSR, but he
    argued that those offenses were not violent felonies.
    The district court understood our decision in United
    States      v.    Luna,   
    649 F.3d 91
      (1st   Cir.   2011),   to    hold    that
    9
    The PSR lists nine different counts of armed robbery, based
    on events that occurred on seven different dates, in six different
    paragraphs. We have not been asked to determine how many of these
    convictions arose from separate occasions, so we do not decide
    this question.    Starks has not challenged on appeal that if
    Massachusetts armed robbery is a violent felony, then he has at
    least three prior convictions for violent felonies arising from
    separate occasions.
    - 13 -
    Massachusetts armed robbery is a violent felony under the force
    clause, and it therefore applied the ACCA mandatory minimum.
    Starks objected at the sentencing hearing, arguing that under
    Massachusetts law, it is possible to satisfy the elements of armed
    robbery without using violent force.                On appeal, he raises the
    same argument.        He also argues that if armed robbery is not a
    violent     felony,   then   he   does   not       have   the   requisite   three
    convictions for violent felonies, since unarmed robbery and armed
    assault with intent to rob are not violent felonies either.
    We review a preserved claim that a prior conviction does
    not satisfy the ACCA definition of a violent felony de novo.                 See
    United States v. Faust, 
    853 F.3d 39
    , 50 & n.9 (1st Cir. 2017).
    Our analysis proceeds in two steps.                First, we consider whether
    Massachusetts     unarmed    robbery     is    a    violent     felony.     After
    concluding that it is not, we consider, second, whether armed
    robbery is a violent felony.           Contrary to what the name of the
    offense implies, we conclude that the offense as actually defined
    is not.10    Before getting to this analysis, however, we set out the
    unfortunately reticulated procedure by which we must evaluate
    whether crimes are violent felonies under the force clause.
    10We do not address whether armed assault with intent to rob
    is a violent felony, since Starks does not qualify for the ACCA
    mandatory minimum sentence if neither armed nor unarmed robbery
    are violent felonies.
    - 14 -
    B.
    1.
    A crime only qualifies as a violent felony under the
    force clause if it "has as an element the use, attempted use, or
    threatened use of physical force against the person of another."
    18 U.S.C. § 924(e)(2)(B)(i) (emphasis added).    The Supreme Court
    has interpreted this language to mean that we must take the
    "categorical approach" to determine whether a defendant's prior
    conviction for a certain crime satisfies the force clause.     See
    Shepard v. United States, 
    544 U.S. 13
    , 19 (2005) (describing the
    language of the ACCA as "imposing the categorical approach" by
    "refer[ring] to predicate offenses in terms not of prior conduct
    but of prior 'convictions' and the 'element[s]' of crimes" (quoting
    Taylor v. United States, 
    495 U.S. 575
    , 600–01 (1990))); 
    Taylor, 495 U.S. at 602
    ; 
    Faust, 853 F.3d at 62
    (Barron, J., concurring).
    On this approach, the question does not turn on whether the
    defendant used, attempted to use, or threatened to use violent
    force in committing the crime as a matter of historical fact, but
    on whether the use, attempted use, or threatened use of violent
    force is required to satisfy one of the crime's elements.      See
    United States v. Whindleton, 
    797 F.3d 105
    , 108 (1st Cir. 2015),
    cert. dismissed, 
    137 S. Ct. 23
    (2016), and cert. denied, 137 S.
    Ct. 179 (2016); cf. Mathis v. United States, 
    136 S. Ct. 2243
    , 2248
    (2016) (noting, in an enumerated offense clause case, that the
    - 15 -
    ACCA is concerned with the elements of a crime, and "cares not a
    whit" about the facts underlying a particular conviction); 
    id. at 2251–52
    (collecting cases saying similar things); Descamps v.
    United States, 
    133 S. Ct. 2276
    , 2283 (2013).         A court determining
    whether a crime satisfies the force clause therefore does not focus
    on the name of the offense, or on what we think someone convicted
    of the offense likely did.         See 
    Taylor, 495 U.S. at 590
    –91, 600–
    02.    Rather, we consider only whether the least serious conduct
    for which there is a "realistic probability" of a charge and
    conviction necessarily involves the use of violent force.            See
    Moncrieffe v. Holder, 
    133 S. Ct. 1678
    , 1684–85 (2013); United
    States v. Fish, 
    758 F.3d 1
    , 6 (1st Cir. 2014).         In short, even if
    most armed robberies are in fact violent, if a conviction can be
    obtained without proof of violent force, then the offense does not
    qualify as a violent felony under the ACCA's force clause.
    We rely on state law for the elements of the crime and
    what conduct satisfies those elements.         See Johnson 
    I, 559 U.S. at 138
    .    In determining whether the least serious conduct that
    satisfies those elements involves the "use, attempted use, or
    threatened use of physical force against the person of another,"
    however, we interpret a federal statute and do not defer to state
    law.   See 
    id. The above
    analysis must be modified to address crimes
    that   can   be   committed   in    multiple   different   ways.   "Some
    - 16 -
    statutes    .    .    .    have   a   more   complicated    (sometimes    called
    'divisible') structure . . . .           A single statute may list elements
    in the alternative, and thereby define multiple crimes."                 
    Mathis, 136 S. Ct. at 2249
    .          "To address that need, th[e Supreme] Court
    approved the 'modified categorical approach' for use with statutes
    having multiple alternative elements."              
    Id. "Under that
    approach,
    a sentencing court looks to a limited class of documents (for
    example, the indictment, jury instructions, or plea agreement and
    colloquy) to determine what crime, with what elements, a defendant
    was convicted of."         
    Id. (citing, inter
    alia, 
    Shepard, 544 U.S. at 26
    ); see also United States v. Castleman, 
    134 S. Ct. 1405
    , 1414
    (2014) (applying modified categorical approach when analyzing
    crime under the force clause of the definition of a misdemeanor
    crime of domestic violence); Johnson 
    I, 559 U.S. at 144
    –45 (noting
    that modified categorical analysis would limit the "practical
    effect" of the Court's interpretation of ACCA's force clause).                We
    call this limited class of documents "Shepard documents."
    Not      all   crimes     that   can   be   committed   in   multiple
    different ways are divisible into multiple crimes with different
    elements.       There is "a different kind of alternatively phrased
    law:   not one that lists multiple elements disjunctively, but
    instead one that enumerates various factual means of committing a
    single element." 
    Mathis, 136 S. Ct. at 2249
    . In order to determine
    whether a crime that may be committed in multiple different ways
    - 17 -
    is divisible, we must be able to distinguish between crimes that
    have alternative elements and crimes that have a single set of
    elements that may be satisfied by different means.
    The Supreme Court and this court have recognized several
    ways of distinguishing elements from means.       Most fundamentally,
    elements must be found unanimously by a jury, while means need not
    be.   See 
    id. at 2248.
       So, in Mathis, the Court concluded that an
    Iowa burglary statute that criminalized the burglary of a number
    of different locations was indivisible because the Iowa Supreme
    Court had held that "a jury need not agree on which of the locations
    was actually involved."    
    Id. at 2250
    (quoting State v. Duncan, 
    312 N.W.2d 519
    , 523 (Iowa 1981)). Following Mathis, we have identified
    the elements of a crime by determining what facts the state supreme
    court requires a jury to find unanimously.       See United States v.
    Tavares, 
    843 F.3d 1
    , 15 (1st Cir. 2016), reh'g denied, 
    849 F.3d 529
    (1st Cir. 2017).     The relevant state model jury instructions
    provide guidance on that question.       See 
    Faust, 853 F.3d at 57
    –58.
    The text of the criminal statute itself may also distinguish
    elements from means.     "If statutory alternatives carry different
    punishments, then . . . they must be elements. . . .     And a statute
    may itself identify which things must be charged (and so are
    elements) and which need not be (and so are means)."      
    Mathis, 136 S. Ct. at 2256
    ; see also 
    Descamps, 133 S. Ct. at 2290
    ("A prosecutor
    - 18 -
    charging a violation of a divisible statute must generally select
    the relevant element from its list of alternatives.").
    Finally, "if state law fails to provide clear answers"
    about what is an element and what is a means, "federal judges have
    another place to look:     the record of a prior conviction itself."
    
    Mathis, 136 S. Ct. at 2256
    .       By "the record of a prior conviction"
    Mathis means, we assume, the Shepard documents.              Mathis provides
    an example:
    Suppose, for example, that one count of an
    indictment and correlative jury instructions
    charge a defendant with burgling a 'building,
    structure, or vehicle' . . . .      That is as
    clear an indication as any that each
    alternative is only a possible means of
    commission, not an element that the prosecutor
    must prove to a jury beyond a reasonable
    doubt. So too if those documents use a single
    umbrella term like 'premises':     Once again,
    the record would then reveal what the
    prosecutor has to (and does not have to)
    demonstrate to prevail.        Conversely, an
    indictment   and   jury   instructions   could
    indicate, by referencing one alternative term
    to the exclusion of all others, that the
    statute contains a list of elements, each one
    of which goes toward a separate crime.
    
    Id. at 2257
    (citation omitted).              If neither state law nor the
    Shepard   documents    "speak    plainly"      about   whether   a   crime   is
    divisible, a sentencing court must assume that it is not.             See 
    id. The divisibility
    analysis must also recognize that state
    laws can change over time.         For instance, a state crime may be
    divisible   at   one   point    but,   due   to   an   intervening   piece   of
    - 19 -
    legislation or court decision, become indivisible or unclear.                  In
    the ACCA context, this court has held that the relevant question
    is whether the crime was divisible at the time of the defendant's
    prior conviction.      See 
    Faust, 853 F.3d at 57
    (citing McNeill v.
    United States, 
    563 U.S. 816
    , 820 (2011)).           This approach comports
    with Mathis, as consulting the Shepard documents to ascertain
    divisibility will yield an answer that is indexed to the time at
    which the defendant was charged with and convicted of the crime.
    2.
    Applying    the   foregoing    mode    of   analysis,       we   first
    consider   whether     Massachusetts     unarmed   robbery   is     a    violent
    felony.    We start with the text of the statute:
    Whoever, not being armed with a dangerous
    weapon, by force and violence, or by assault
    and putting in fear, robs, steals, or takes
    from the person of another, or from his
    immediate control, money or other property
    which may be the subject of larceny, shall be
    punished by imprisonment in the state prison
    for life or for any term of years.
    Mass. Gen. Laws ch. 265, § 19(b).          This statute contains several
    lists of different ways to commit the crime.            For the purposes of
    this opinion, we focus on one set of alternatives:                robbery "by
    force and violence" and robbery "by assault and putting in fear."
    Massachusetts courts describe these alternatives as involving
    different types of force: "actual force" and "constructive force."
    - 20 -
    See, e.g., Commonwealth v. Jones (Jones I), 
    283 N.E.2d 840
    , 843
    (Mass. 1972).
    The government does not argue that Massachusetts unarmed
    robbery is divisible into different crimes based on the type of
    force used.     We accept this concession and do not decide the
    issue.11   Given the government's concession, if either way of
    committing unarmed robbery is not a violent felony, unarmed robbery
    is categorically not a violent felony.
    Starks's argument that unarmed robbery is not a violent
    felony focuses on the actual-force form of the offense, and we
    follow his lead.12   According to the Massachusetts Supreme Judicial
    11 No precedent plainly calls into question the correctness
    of the government's concession. The Massachusetts Appeals Court
    has concluded that an indictment for unarmed robbery need not
    charge what type of force the defendant used. See Commonwealth v.
    Jones (Jones II), 
    426 N.E.2d 726
    , 727 (Mass. App. Ct. 1981) ("The
    particular type of force, actual or constructive, by which the
    robbery is committed is not an essential element of the crime, and
    it need not be pleaded in the indictment.").      This holding is
    consistent with the language Massachusetts statutory law has long
    deemed "sufficient" for a robbery indictment. See Mass. Gen. Laws
    ch. 277, § 79 ("Robbery. (Under Chap. 265, Sec. 19.)--That A.B.
    did assault C.D. with intent to rob him, and thereby did rob and
    steal from the person of said C.D. (mention the property) of the
    property of said C.D."); An Act to Provide for the Simplification
    of Criminal Pleadings, 1899 Mass. Acts 411, 432 (listing form of
    robbery indictment identical to that provided in modern statute).
    This rule, extant at the time of all of Starks's robbery
    convictions, may support a conclusion that unarmed robbery is not
    divisible. See 
    Mathis, 136 S. Ct. at 2256
    ; 
    Descamps, 133 S. Ct. at 2290
    .
    12 Starks may have focused his argument in this way because
    there is a good argument that constructive-force unarmed robbery
    has as an element the threatened use of physical force against the
    person of another. To prove the constructive-force form of the
    - 21 -
    Court (SJC), "[w]hether actual or constructive force is employed,
    the degree of force is immaterial so long as it is sufficient to
    obtain the victim's property 'against his will.'"      
    Id. at 843
    (quoting Mass. Gen. Laws ch. 277, § 39).   Jones I illustrates how
    little force is necessary for an unarmed robbery conviction.   That
    case considered whether a purse snatching, which the victim did
    not resist, involved the use of actual force.    The SJC held that
    purse snatching
    necessarily involves the exercise of some
    actual force . . . . [W]here, as here, the
    actual force used is sufficient to produce
    awareness, although the action may be so swift
    as to leave the victim momentarily in a dazed
    condition, the requisite degree of force is
    present to make the crime robbery.
    
    Id. at 845.
      As the Massachusetts Appeals Court has put it, under
    Jones I, "the bare act of snatching a purse from the hand of a
    victim, in the absence of any prior awareness by the victim of the
    offense, "there must be, in addition to the elements of simple
    larceny, some objectively menacing conduct by the defendant,
    undertaken with the intent to put the victim in fear for the
    purpose of stealing his property, and resulting in reasonable fear
    or apprehension on the part of the victim facilitating the theft."
    Commonwealth v. Marcotte, 
    466 N.E.2d 127
    , 129 (Mass. App. Ct. 1984)
    (in armed robbery case); see Commonwealth v. Davis, 
    873 N.E.2d 1200
    , 1202 (Mass. App. Ct. 2007) (same in unarmed robbery case);
    see also Commonwealth v. Garrett, 
    41 N.E.3d 28
    , 37 (Mass. 2015)
    (actual fear or apprehension required for constructive-force
    unarmed robbery); Commonwealth v. Joyner, 
    4 N.E.3d 282
    , 293 (Mass.
    2014) (for constructive-force armed robbery, "objectively menacing
    conduct" and "intent to put the victim in fear" are required
    (quoting   
    Marcotte, 466 N.E.2d at 129
    )).      Thus,   name
    notwithstanding, the actual-force form of unarmed robbery may be
    the less serious form of the offense.
    - 22 -
    impending act, is sufficient to constitute the element of force
    required for unarmed robbery" even where the defendant "touch[es]
    neither [the victim's] hand nor . . . body."         Commonwealth v.
    Brown, 
    318 N.E.2d 486
    , 487 (Mass. App. Ct. 1974).    Jones I remains
    good law.     See Commonwealth v. Zangari, 
    677 N.E.2d 702
    , 702–03
    (Mass. App. Ct. 1997) (upholding a conviction for unarmed robbery
    where, after the victim was dropped off outside her home and walked
    up the steps, "[s]he felt someone snatch her purse from under her
    arm," "[s]he was stunned," and, "[t]urning, she saw the back of a
    man running down [the street]"); see also Commonwealth v. Moran,
    
    442 N.E.2d 399
    , 403 (Mass. 1982); Commonwealth v. Ahart, 
    641 N.E.2d 127
    , 131 (Mass. App. Ct. 1994).
    The government points to passages in Jones I that explain
    the SJC's reasoning to argue that robbery satisfies the force
    clause.     For instance, the SJC noted that "[h]istorically . . .
    the law has singled out the robber from other thieves because of
    his readiness to inflict bodily injury upon his victims." Jones 
    I, 283 N.E.2d at 844
    . The SJC also distinguished robbery from larceny
    in a footnote by quoting a draft of the Model Penal Code:       "The
    ordinary citizen feels himself able to guard against surreptitious
    larceny . . . to some extent, by his own wits or caution.     But he
    abhors . . . (the robber[] whose) hardihood . . . enables him to
    carry out his purpose in the presence of his victim and over his
    opposition."    
    Id. at 844
    n.6 (quoting Model Penal Code § 222.1,
    - 23 -
    cmts. (Am. Law Inst., Tentative Draft No. 11, 1960))).                      In the
    government's view, these observations mean that the actual-force
    form of Massachusetts robbery "has as an element the . . .
    threatened use of physical force against the person of another."
    18 U.S.C. § 924(e)(2)(B)(i).
    We are not persuaded. The SJC offered these observations
    to justify its decision to depart from the more common rule, under
    which robbery requires some resistance by or injury to the victim,
    and to require only sufficient force to make the victim aware of
    the taking.    See Jones 
    I, 283 N.E.2d at 844
    –45, 844 n.5.                  Despite
    these observations, to convict a defendant of robbery by actual
    force, a jury need not find that the victim felt threatened, that
    the defendant intended to use violent force if the victim resisted,
    or that the use of violent force was otherwise impending.                       See
    United States v. Delgado-Sánchez, 
    849 F.3d 1
    , 10 (1st Cir. 2017)
    (noting    ambiguity     in   meaning     of   "threatened   use     of   physical
    force").    The SJC's observations amount to the judicial equivalent
    of the Maine legislature's decision to label the mere possession
    of two grams of a mixture containing heroin "trafficking."                      See
    United    States    v.   Mulkern,   
    854 F.3d 87
    ,   96   (1st    Cir.    2017).
    Whatever    label    state    law   may    give   an    offense     and   whatever
    justification a state may offer for defining an offense in a
    particular way, the ACCA definition of a violent felony turns on
    a crime's elements, not the beliefs that may have led to the
    - 24 -
    adoption of those elements.         Cf. 
    id. (quoting, inter
    alia, 
    Taylor, 495 U.S. at 590
    –91).
    Thus, under the actual holding of Jones I, as interpreted
    and applied by the Massachusetts courts, the minimum conduct
    criminalized by the unarmed robbery statute is snatching a purse
    using just enough force to make the victim aware of the purse
    snatching, but without touching the victim, without any awareness
    by the victim of the impending act, and without any intention to
    use force against the victim if the victim resists.                    It is a
    question of federal law whether such conduct involves "force
    capable of causing physical pain or injury to another person."
    Johnson 
    I, 559 U.S. at 140
    .          We conclude that it does not.
    This result follows from our precedent.            In Mulkern, we
    held that one subsection of Maine's robbery statute was not a
    violent felony because the Maine Law Court had concluded that "'any
    physical force'--e.g., pulling a purse from a person's hand--[wa]s
    'sufficient force to convict of robbery'" under that subsection.
    
    Mulkern, 854 F.3d at 92
    –94 (quoting Raymond v. State, 
    467 A.2d 161
    , 164–65 (Me. 1983)).           In reaching that conclusion, the Maine
    Law   Court     had    described    the   SJC's   opinion   in    Jones   I   as
    "persuasive."         
    Raymond, 467 A.2d at 164
    .      Although in Mulkern we
    explicitly disclaimed expressing any opinion on Massachusetts law,
    
    see 854 F.3d at 94
    , the logic of the opinion extends directly to
    unarmed robbery as defined by Jones I.            Likewise, in United States
    - 25 -
    v. Castro-Vazquez, 
    802 F.3d 28
    (1st Cir. 2015), we stated in dicta
    that if Puerto Rico law allowed a conviction for robbery based on
    the "slightest use of force," it would not qualify as a violent
    felony under the force clause.       
    Id. at 37–38.
        And in United States
    v.   Martinez,   
    762 F.3d 127
       (1st    Cir.    2014),   we   held   that
    Massachusetts simple assault is not a crime of violence under the
    force clause of the career-offender sentencing guideline because
    an assault could be accomplished by an attempted or threatened
    "mere touching."    
    Id. at 137-38.
        As Massachusetts unarmed robbery
    only requires force sufficient to make the victim aware of the
    theft, it may involve no more force against the victim than a mere
    touching.     Under our precedent, therefore, Massachusetts unarmed
    robbery does not satisfy the force clause of the ACCA.
    3.
    Turning to Massachusetts armed robbery, we start once
    again with the language of the statute.             The Massachusetts armed
    robbery statute reads:
    Whoever,   being armed with a dangerous weapon,
    assaults    another and robs, steals or takes
    from his   person money or other property which
    may be     the subject of larceny shall be
    punished   by imprisonment in the state prison
    for life   or for any term of years . . . .
    Mass. Gen. Laws ch. 265, § 17.        The SJC has parsed these elements
    as follows:
    The elements of the crime of armed robbery are
    that a defendant, while armed with a dangerous
    - 26 -
    weapon, assaulted another person, and took
    money or property from the person with the
    intent to steal it. A defendant need not have
    used or displayed the dangerous weapon during
    the robbery; it is sufficient that the
    prosecutor prove that the robber possessed the
    dangerous weapon during the robbery.
    Commonwealth    v.     Anderson,   
    963 N.E.2d 704
    ,    718    (Mass.    2012)
    (citations omitted).       Crucially, "the crime of armed robbery does
    not   require   that    the   perpetrator   utilize      the    weapon    in   the
    perpetration of the robbery. . . .           Similarly, the perpetrator
    need not display the weapon or otherwise make the victim aware of
    its presence."       Commonwealth v. Rogers, 
    945 N.E.2d 295
    , 301 n.6
    (Mass. 2011); see also King v. MacEachern, 
    665 F.3d 247
    , 253 & n.7
    (1st Cir. 2011) (recognizing this point and collecting cases
    establishing it); Commonwealth v. Nickologines, 
    76 N.E.2d 649
    , 651
    (Mass. 1948) ("It is not necessary to show the use of a dangerous
    weapon in proving the offence of robbery while armed.              The gist of
    the offence is being armed, not the use of the weapon.").13
    13
    Between Nickologines and Rogers, at least one SJC opinion
    contained language that could be read to signal a departure from
    this rule.   See Commonwealth v. Appleby, 
    402 N.E.2d 1051
    , 1057
    (Mass. 1980) ("The gist of the offense of armed robbery is robbery
    'while armed,' and thus there is no need to prove the defendant
    used a weapon other than to threaten.").        Nevertheless, the
    government has conceded that Rogers correctly states the
    Massachusetts law of armed robbery as it applied to Starks. The
    government makes no argument that the law differed in 1991, 1996,
    or 1998, the years of Starks's convictions.
    - 27 -
    The   government   concedes   that   armed   robbery   is   not
    divisible. We accept this concession and do not decide the issue.14
    Accordingly, armed robbery qualifies as a predicate offense under
    the ACCA only if both ways of committing it are violent felonies.
    We focus once again on the actual-force form of armed
    robbery.   Starks argues that this form of armed robbery is not a
    violent felony because it requires no more force than the actual-
    force form of unarmed robbery.      The only difference between the
    two crimes is that a defendant convicted of armed robbery must
    14 This concession, too, stands unrejected by the case law.
    Indeed, there is Massachusetts case law holding that a jury need
    not be unanimous about whether armed robbery was committed by force
    or by threat of force. In Commonwealth v. Santos, the SJC held:
    There was no requirement that the jury agree
    as to precisely which threat, or which
    application of force, caused the victim to
    part with her money, and it would thus be
    pointless to require them to agree that it was
    one or more of the threats as opposed to one
    or more of the applications of force that
    succeeded in convincing [the victim] not to
    resist the taking.     The jury need not be
    unanimous as to that detail . . . .
    
    797 N.E.2d 1191
    , 1196 (Mass. 2003), overruled in part on other
    grounds by 
    Anderson, 963 N.E.2d at 718
    –19; see also Commonwealth
    v. Porro, 
    939 N.E.2d 1157
    , 1165 (Mass. 2010) (reaffirming Santos
    in dicta and stating that "we do not require that a jury be
    unanimous as to which theory of assault forms the basis for their
    verdict"). All of Starks's convictions for armed robbery occurred
    before the SJC issued the Santos decision. Adopting the historical
    approach required by 
    Faust, 853 F.3d at 57
    , we would have to
    determine the state of the law before Santos.           While the
    Massachusetts Appeals Court's opinion in Jones 
    II, 426 N.E.2d at 727
    , noted above, may apply to armed robbery and may inform such
    an analysis, we need not and do not decide that here.
    - 28 -
    possess a weapon during the robbery, though the victim need not be
    aware of it.      So, a person who has a knife in his pocket as he
    snatches    a    victim's    purse     is    guilty       of   armed   robbery   in
    Massachusetts, even if the knife is not used or displayed during
    the robbery.      Pointing to the minimal force requirement and the
    lack of any requirement that the victim even be aware of the
    weapon, the Ninth Circuit recently held that Massachusetts armed
    robbery is not a violent felony under the force clause. See United
    States v. Parnell, 
    818 F.3d 974
    , 979-82 (9th Cir. 2016); 
    id. at 982
    (Watford, J., concurring).
    This argument can only succeed if Jones I applies to
    armed robbery.      We note that there is a difference in the wording
    of the unarmed robbery and armed robbery statutes. Unarmed robbery
    requires that the defendant "by force and violence, or by assault
    and putting in fear, robs, steals, or takes from the person of
    another," Mass. Gen. Laws ch. 265, § 19(b), while armed robbery
    requires that the defendant "assaults another and robs, steals, or
    takes"   the    person's    property,       
    id. § 17.
       Nevertheless,     the
    Massachusetts cases on robbery do not differentiate between the
    assault element of armed robbery and the force element of unarmed
    robbery.    See, e.g., Commonwealth v. Santos, 
    797 N.E.2d 1191
    , 1196
    (Mass. 2003) (describing the assault element of armed robbery as
    requiring      either   a   "threat"    or    an       "application    of   force"),
    overruled in part on other grounds by 
    Anderson, 963 N.E.2d at 718
    –
    - 29 -
    19; Commonwealth v. Tarrant, 
    326 N.E.2d 710
    , 713 (Mass. 1975) ("The
    offense of robbery while armed is but an aggravated form of common
    law robbery and is to be distinguished in main by the manner of
    punishment and not by the material elements composing the common
    law crime of robbery."); Commonwealth v. Richards, 
    293 N.E.2d 854
    ,
    857 (Mass. 1973) (stating that both unarmed robbery and armed
    robbery can be committed in two ways:          "by force applied to the
    person, with intent to steal, or by an assault putting the person
    in fear, with the same intent"); Commonwealth v. Novicki, 
    87 N.E.2d 1
    , 3 (Mass. 1949) (similar).       Indeed, in a recent case describing
    the   force    requirement   of   armed   robbery,   the   SJC    quoted   the
    statement in Jones I that "the degree of force is immaterial so
    long as it is sufficient to obtain the victim's property against
    his will."      See Commonwealth v. Joyner, 
    4 N.E.3d 282
    , 293 (Mass.
    2014) (quoting Jones 
    I, 283 N.E.2d at 843
    ).
    Thus, we conclude that there is no reason, in principle,
    that a purse-snatcher with a knife in his or her pocket could not
    be convicted of armed robbery.        Notably, the government does not
    argue otherwise.      Nor does the government argue that there is no
    reasonable probability that such a person would be charged with
    armed robbery.      Instead, the government recognizes that "because
    the dangerous weapon required to commit an armed robbery need not
    be used or shown during the offense, the analysis of the two crimes
    (armed   and     unarmed   robbery)   [is]   substantially       similar   for
    - 30 -
    purposes of the force clause under the ACCA."   (citation omitted).
    The government makes two primary arguments that armed robbery
    nevertheless satisfies the force clause.
    First, the government argues that both unarmed robbery
    and armed robbery satisfy the force clause because the SJC's
    observations about the threat implicit in robbery entail that all
    forms of robbery satisfy the force clause.    We have rejected this
    argument as to unarmed robbery above and we reject it as to armed
    robbery too.   It is true that when a robber has a dangerous weapon,
    the risk of violence is greater and the SJC's observations about
    the threat implicit in robbery are even more apt.   But the SJC did
    not make the threatened use of force a required element of armed
    robbery.   Thus, even on the SJC's assumption that armed robbery
    generally involves an implicit threat of force, such a threat is
    not present in the least serious conduct for which there is a
    realistic possibility of a charge and conviction for Massachusetts
    armed robbery.    Moreover, to deem an offense qualifying under the
    ACCA because the offense involves a risk of serious injury is to
    rely on the ACCA's residual clause, which was designed to capture
    crimes that "involve[] conduct that presents a serious potential
    risk of physical injury to another." 18 U.S.C. § 924(e)(2)(B)(ii).
    That clause, though, no longer applies.      See Johnson II, 135 S.
    Ct. at 2557.     Nor is the fact that the residual clause has been
    invalidated a reason to read a risk evaluation into the analysis
    - 31 -
    of the force clause--indeed, it is a reason not to do so.                  Such a
    reading     could   potentially       render     the   force     clause     itself
    susceptible to a vagueness challenge.
    Second, the government argues that we are bound to agree
    that armed robbery is a violent felony by our opinion in Luna.                  In
    Luna, this court did hold that Massachusetts armed robbery was a
    violent felony under the force 
    clause. 649 F.3d at 107-09
    .
    Intervening decisions by the Supreme Court have not cast doubt on
    this decision.       The Luna opinion issued after the Johnson I
    decision,      addressed    whether    the     crime   of   armed     robbery   in
    Massachusetts involves violent force, and it concluded that it
    does.   
    Id. Luna did
    not rely on the residual clause, so Johnson II
    did not undermine it.         Nothing in Luna suggests that the panel
    applied   the    modified     categorical      approach     to   an   indivisible
    statute, the error identified in 
    Descamps, 133 S. Ct. at 2283
    , and
    
    Mathis, 136 S. Ct. at 2250
    –51.          Indeed, the Luna panel explicitly
    stated that both forms of armed robbery satisfied the force clause.
    
    See 649 F.3d at 108
    n.18.
    Nevertheless, Luna did not address the precise issue
    before this panel.         The defendant in that case did not make, and
    therefore waived, the argument that Starks now presses.                   Instead,
    the defendant in Luna argued that the elements of armed robbery
    could be satisfied "if a defendant, while armed, puts his victim
    in fear using threatening words or gestures," and that therefore
    - 32 -
    "the crime does not require violent force."             
    Id. at 108.
        This
    court, understandably, rejected that argument on the ground that
    an armed robbery involving only threatening words or gestures
    satisfies the force clause because it has as an element the
    threatened use of physical force.            
    Id. Luna therefore
    only
    meaningfully   considered    a     single   argument    relating   to    the
    constructive-force form of armed robbery.
    We   recognize    that   the   Luna   opinion's   conclusion    is
    phrased in broad terms. A footnote states that both forms of armed
    robbery "are proper ACCA predicates, as discussed below," 
    id. at 108
    n.18, though the opinion contains no further discussion of the
    actual-force form of armed robbery.         The discussion of the force
    clause ends with:    "Luna has also provided no reason for us to
    conclude that the type of force involved in armed robbery is not
    'violent force--that is, force capable of causing physical pain or
    injury,' and we see no reason to do so."           
    Id. at 108-09
    (emphasis
    added) (quoting Johnson 
    I, 559 U.S. at 140
    ). The underlined clause
    may be read to imply that the court independently considered other
    arguments that armed robbery does not satisfy the force clause,
    which Luna had failed to raise.15
    15We note, however, that Luna does not cite the SJC's opinion
    in Jones I.    Nor does it recognize that to satisfy the force
    element of robbery in Massachusetts, "the degree of force is
    immaterial so long as it is sufficient to obtain the victim's
    property 'against his will.'" Jones 
    I, 283 N.E.2d at 843
    (quoting
    Mass. Gen. Laws ch. 277, § 39).
    - 33 -
    We conclude that this expansive language from Luna is
    dicta. It was presented without analysis and, because it addressed
    a broader argument about whether armed robbery qualifies as a
    violent felony that the defendant had waived, it was not necessary
    to the court's conclusion.           We are not bound to follow it.             See
    Arcam Pharm. Corp. v. Faría, 
    513 F.3d 1
    , 3 (1st Cir. 2007) ("We
    have    held    that   'when   a   statement    in   a   judicial    decision    is
    essential to the result reached in the case, it becomes part of
    the court's holding.'          The result, along with those portions of
    the opinion necessary to the result, are binding, whereas dicta is
    not." (quoting Rossiter v. Potter, 
    357 F.3d 26
    , 31 (1st Cir.
    2004))); Dedham Water Co. v. Cumberland Farms Dairy, Inc., 
    972 F.2d 453
    , 459 (1st Cir. 1992) (similar); McCoy v. Mass. Inst. of
    Tech., 
    950 F.2d 13
    , 19 (1st Cir. 1991) (similar).16
    Our decision in United States v. Whindleton also does
    not require us to conclude that armed robbery satisfies the force
    clause.     We cannot draw the same distinction between Massachusetts
    unarmed     robbery     and    armed    robbery      that   we      drew   between
    16
    Following the procedure described in cases such as United
    States v. Holloway, 
    630 F.3d 252
    , 255 n.2 (1st Cir. 2011) and
    United States v. Gendron, 
    18 F.3d 955
    , 967 (1st Cir. 1994), the
    panel opinion in this case was circulated to all active judges of
    the court, none of whom objected to our treatment of Luna. "We
    caution that the use of this informal procedure does not convert
    this opinion into an opinion en banc, nor does it preclude a
    suggestion of rehearing en banc on any issue in the case . . . ."

    Massachusetts assault and assault with a dangerous weapon (ADW)
    when we concluded in Whindleton that ADW necessarily involves
    violent force even though assault does not.   
    See 797 F.3d at 111
    -
    16; see also United States v. Hudson, 
    823 F.3d 11
    , 17 (1st Cir.
    2016) (holding that under the ACCA, Massachusetts ADW necessarily
    involves the use of violent force).    In Whindleton, "[i]t [wa]s
    critical that the statute at issue . . . [wa]s Assault with a
    Dangerous Weapon" because,
    [l]ogically, the harm threatened by an 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. As a
    result, the element of a dangerous weapon
    imports the 'violent force' required by
    [Johnson I] into the otherwise overbroad
    simple assault statute.
    
    Whindleton, 797 F.3d at 113
    –14.   Similar reasoning does not apply
    here because armed robbery, unlike ADW, does not require the use
    of the dangerous weapon.     Thus, we cannot find, as we did in
    Whindleton, that armed robbery requires any sort of "touching . . .
    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. at 114.
      In the absence of this factor, we see no basis for
    concluding that armed robbery requires a greater degree of force
    than unarmed robbery.
    - 35 -
    4.
    Once again, the immensely complicated analysis required
    by the categorical approach for measuring state crimes against the
    standards set forth in the ACCA (or similar statutes) leads to a
    conclusion that a conviction for a violent sounding, serious crime
    is nevertheless not a violent felony (or a crime of violence or
    the like). One might reasonably guess that, in fact, Starks likely
    engaged in conduct that involved the use or threatened use of
    violent force against a person.             Establishing a minimum term of
    incarceration based on the fact someone engaged in certain conduct,
    however, generally requires a jury finding.          See Alleyne v. United
    States, 
    133 S. Ct. 2151
    , 2155 (2013).             With the ACCA, Congress
    sought to avoid the need for such findings by mandating a longer
    sentence based not on conduct, but on bare convictions.                 While
    this works in principle, 
    id. at 2160
    n.1 (citing Almendarez–Torres
    v. United States, 
    523 U.S. 224
    (1998)), its use requires that we
    deem the convictions to have been for the least serious conduct
    for   which    there   is   a   realistic   possibility   of   a   charge   and
    conviction.     Thus, if a crime involves a taking of $1 to $1000, we
    must assume that a conviction was for taking $1.               Similarly, in
    this case, we assume that Starks's many convictions were based on
    the least amount of force required by the pertinent laws and hold
    that that small level of force (i.e., touching) is not the violent
    force that the ACCA requires.          We therefore reverse the district
    - 36 -
    court's   ruling    that   the   ACCA's    180-month   mandatory   minimum
    sentence applied.
    III.
    For the foregoing reasons, we affirm Starks's conviction
    but vacate his sentence and remand for resentencing.
