    February 16, 2021
    LIPEZ, Circuit Judge.    In August 2019, the United States
    Probation Department in Worcester, Massachusetts ("the Probation
    Office" or "Probation"), petitioned for the arrest of appellant
    Daniel    Frederickson   for   violating   his       supervised    release   by
    committing a new offense -- assaulting a U.S. Probation Office
    employee.      A   criminal    complaint       was    also    issued    against
    Frederickson for the alleged assault.          After a three-day trial, a
    jury   acquitted   Frederickson   of     the    criminal      assault   charge.
    Subsequently, the district judge who presided at the jury trial
    also presided at a supervised release revocation hearing and
    revoked Frederickson's supervised release on the basis of the same
    conduct.    The court sentenced Frederickson to twenty-four months
    in prison followed by eight months of supervised release.
    Frederickson appeals, alleging that the court improperly
    used acquitted conduct to revoke his supervised release, that the
    evidence did not support a finding of revocation, and that the
    sentence imposed was unreasonable.             After careful review, we
    affirm.
    I.
    We recount the facts as presented at Frederickson's
    revocation hearing in the light most favorable to the government,
    see United States v. Oquendo-Rivera, 
    586 F.3d 63
    , 66-67 (1st Cir.
    2009), except where presenting conflicting testimony is necessary
    to understand the legal issues in this appeal.               At the revocation
    - 2 -
    hearing,     the     parties        relied    primarily      on    transcripts    of
    Frederickson's           criminal     assault       trial.         The   government
    supplemented       its    evidence    with    two     additional    witnesses,   but
    Frederickson relied solely on his presentation at trial, which
    consisted of his testimony as the only witness in his defense.
    Hence, in recounting the facts, we rely heavily on memorialized
    trial testimony as proffered by the parties and supplemented by
    the government at the revocation hearing.
    A.    Supervised Release and the Assault
    In November 2017, Frederickson pled guilty to conspiracy
    to possess with intent to distribute steroids, in violation of 
    21 U.S.C. § 846
    , and possession of a tableting machine, in violation
    of 
    21 U.S.C. § 843
    (a)(6).              He was sentenced to three years of
    supervised release.             As a condition of his release, Frederickson
    was required to submit to regularly scheduled drug testing at the
    U.S. Probation Office.            He was also prohibited from committing any
    additional state or federal crimes.
    Paul Walter, who was twenty-six years old at the time of
    these   events,     was     a    student     intern    in   the   Probation   Office
    beginning in January 2017.            As an intern, he was responsible for,
    among     other    things,        answering     the    phone,      handling   faxes,
    monitoring home detention, and collecting urine samples.                      Walter
    testified that, beginning in late 2017, he collected urine samples
    from Frederickson one to three times a month until August 20, 2019.
    - 3 -
    On that date, Frederickson arrived at the Probation
    Office for a scheduled urine test.           Walter greeted Frederickson,
    observed him pass through a metal detector, and unlocked the
    bathroom door for Frederickson to enter from the lobby.                Walter
    then entered the bathroom from a second door leading to the
    offices, handed Frederickson a urine sample cup, and left the
    bathroom through that same door to allow Frederickson to provide
    the sample.       Shortly thereafter, Frederickson either knocked on
    the door to the offices or yelled for Walter to reenter the
    bathroom.     Walter and Frederickson provided conflicting accounts
    of what happened next.
    Walter contends that when he reentered the bathroom, he
    inspected Frederickson's sample and determined that there was an
    insufficient amount of urine.         Walter asked whether Frederickson
    needed additional time or a glass of water to produce a sufficient
    sample,     but   Frederickson   declined.       Walter    testified    that
    Frederickson      suddenly   began    walking   toward    him   and    asking
    questions such as "Why are we here?" and "What do you even do
    here?"    Walter tried to leave the bathroom but was met by a closed
    fist punch to the left side of his face by Frederickson.               Walter
    contends that Frederickson proceeded to violently assault him by
    placing him in a chokehold, strangling him, and slamming his head
    against a wall, table, and the floor while Walter pleaded for his
    life.
    - 4 -
    According to Frederickson, when Walter initially entered
    the bathroom to provide the sample cup, Walter made several
    comments about Frederickson's appearance, such as, "[y]ou look
    good,"   and   "you   have      really    nice    calf     muscles,"      and   asked
    Frederickson     whether   he    had     been    working    out.     Frederickson
    testified that he felt as though Walter was "hitting on [him]."
    According to Frederickson, when Walter reentered the bathroom to
    inspect the sample, he said it was insufficient and proceeded to
    "pat" Frederickson's genitals, and stated "you can do a little
    better than that."      Frederickson said he was "stunned" by Walter's
    sexual assault and immediately punched Walter in his left eye.
    Frederickson contends that thereafter he was in a state of shock
    and remembers only that he ended up on the bathroom floor holding
    Walter down by his shoulders and asking him "What the hell was
    that?" and "What do you even do here?"
    The   only   other     individual       present    in    the   Probation
    Office at the time of the assault was Probation Officer Ryan Skal,
    who testified at the trial that he heard a loud thumping coming
    from the bathroom and went to investigate.                   When he opened the
    bathroom door, Officer Skal observed Frederickson holding Walter
    in a chokehold on the floor.           He testified that Walter appeared to
    be struggling to breathe.         He closed the bathroom door and ran to
    call for emergency services.           After calling 911 and reporting the
    assault,   Officer    Skal   returned       to    the    bathroom   and    observed
    - 5 -
    Frederickson     continuing        to        strangle     Walter.       Skal        urged
    Frederickson to desist and, "after a few prompts," Frederickson
    acquiesced.     Officer Skal then ordered Frederickson to leave the
    Probation Office immediately, and Frederickson complied.                       Officer
    Skal did not testify that Frederickson had told him that Walter
    had sexually assaulted him.
    After Frederickson left the Probation Office, Worcester
    Police    Officer   Keith    Garlick          recognized      Frederickson's         name
    because he was "familiar with                  the   family."       Officer Garlick
    notified Frederickson's family of the assault allegations and,
    shortly    thereafter,    Frederickson's             sister    drove   him     to    the
    Worcester Police Station.          Officer Garlick testified, as one of
    the two additional witnesses presented by the government at the
    revocation     hearing,     that        he     arrested    Frederickson        without
    Mirandizing1 him and that Frederickson remained silent and had no
    visible injuries.
    B.     The Jury Verdict and Supervised Release Revocation
    Frederickson was indicted on one count of assaulting a
    federal employee, in violation of 
    18 U.S.C. § 111
    .                     The Worcester
    District Court had also issued a criminal complaint charging
    Frederickson with various state crimes, but all were dismissed
    after Frederickson was federally indicted.                    The Probation Office
    1    See Miranda v. Arizona, 
    384 U.S. 436
    , 444-45, 467-74 (1966).
    - 6 -
    separately sought revocation of Frederickson's supervised release
    for his November 2017 offense on the ground that Frederickson had
    violated the conditions of his release by "committ[ing] another
    federal, state, or local crime."     At the government's request, the
    court continued the revocation hearing until after the assault
    trial.
    The trial occurred in December 2019 and lasted three
    days.    On the final day, the court instructed the jury on the
    elements of forcibly assaulting a federal employee.             The court
    also instructed the jury on self-defense:
    The defendant has testified that he acted in
    self-defense.    Therefore, in addition to
    proving all the elements of the crime beyond
    a reasonable doubt, the [g]overnment must also
    prove beyond a reasonable doubt that the
    defendant did not act in self-defense.       A
    defendant may use force in self-defense
    against a federal officer if: One, the
    defendant reasonably believed that the use of
    force was necessary to defend himself against
    an immediate use of unlawful force or unlawful
    contact; and two, the defendant used no more
    force than appeared reasonably necessary in
    the circumstances. However, a person who is
    the initial aggressor cannot later claim self-
    defense as a justification for the assault.
    After    approximately   three   hours    of   deliberations,   the   jury
    returned a verdict of not guilty.
    Directly following the acquittal, the court convened a
    bail hearing regarding Frederickson's ongoing detention for his
    alleged supervised release violation based on the same conduct --
    - 7 -
    assaulting Walter.     Despite the acquittal, the government insisted
    on pursuing the supervised release violation, given the lower
    burden of proof (by a preponderance of the evidence) applicable at
    revocation proceedings.     The court ordered Frederickson detained
    pending the revocation hearing.
    The   day   before   the    revocation   hearing,    the   court
    convened a telephone conference primarily to hear argument as to
    "whether the court may consider acquitted conduct in reaching its
    decision on revocation."     At that hearing, the government notified
    Frederickson that it intended to argue at the revocation hearing
    that Frederickson violated supervised release by (1) assaulting a
    federal employee in violation of 
    18 U.S.C. § 111
     (the federal
    assault charge that was the subject of the criminal trial), and
    (2) committing simple assault and battery in violation of Mass.
    Gen. Laws ch. 265, § 13A (the state assault and battery charge
    that was dismissed).
    The revocation hearing was held on December 20, 2019.
    At the outset, the court announced its legal conclusions as to the
    issues discussed at the telephone conference.        The court concluded
    that   nothing   "prevent[ed]   [it]    from   considering     whether   the
    defendant violated 18 U.S.C. [§] 111 under a preponderance of the
    evidence standard, and on that basis [the court could revoke
    Frederickson's] supervised release."        The court further concluded
    - 8 -
    that   it   could   also   consider    whether     Frederickson's       conduct
    violated state or local law.
    Frederickson    argued    that   he    acted    in    self-defense,
    relying on his memorialized trial testimony.                     The government
    similarly relied on the evidence it presented at trial, which
    consisted of photographic evidence of Walter's injuries and the
    crime scene, Walter's medical records, and the testimony of four
    witnesses -- Walter; Officer Skal; Officer Anthony Correa, who
    responded to the 911 call at the Probation Office; and Barbara
    Hazen, a receptionist at the Probation Office who did not witness
    the assault but arrived at the office shortly after the assault
    occurred.     The    government   supplemented       its    evidence    at    the
    revocation hearing with the live testimony of two additional
    witnesses:    (1) Officer     Keith     Garlick,      who     testified       that
    Frederickson had no visible injuries and did not report being
    sexually assaulted; and (2) Alicia Howarth, a Probation supervisor
    who    testified    that   Walter's     employment     file       contained    no
    disciplinary proceedings or allegations of sexual assault.
    After orally reviewing the evidence, the court stated
    that it "intend[ed] to use the self-defense instruction, the law
    that [it] gave the jury in the trial."            It further clarified that
    it had assessed the evidence and would apply the preponderance of
    the evidence standard.        The court proceeded to announce                  its
    findings on self-defense before turning to the elements of assault.
    - 9 -
    Regarding self-defense, the court concluded that "the
    government      ha[d]      met   its    burden        [of     demonstrating]     by    a
    preponderance of the evidence that the defendant did not act in
    lawful self-defense [because]              . . .       [e]ven if the defendant
    believed that Paul Walter unlawfully had physical contact with
    him,   the     defendant    used   more       force    than    appeared    reasonably
    necessary in the circumstances."                The court noted that the only
    unlawful     physical    contact       that    Frederickson       testified     to    was
    Walter's sexual assault at the beginning of the encounter, which
    the    court     found     did   not     justify       Frederickson's       prolonged
    retaliation. With respect to the alleged sexual assault, the court
    noted that
    there    [was]    just     no    reason    for
    Mr. Frederickson not to say to Officer Skal or
    to anyone that night        "I was sexually
    assaulted. . . . I'm on top of him because he
    assaulted me" . . . .         Mr. Frederickson
    remained without any sort of responsiveness
    and didn't mention to Officer Garlick, who
    apparently knows the family, "Officer Garlick,
    I was sexually assaulted" and talk to him,
    tell him that. Nothing. There was nothing
    that was mentioned.
    Turning to the elements of assault and battery, the court
    held that there, too, the government had met its burden on each
    element of 
    18 U.S.C. § 111
     and Mass. Gen. Laws ch. 265, § 13A.                        It
    concluded      that   Frederickson        willfully         touched    Walter   in    an
    offensive manner likely to cause bodily harm.                         The court noted
    that "Mr. Walter testified that Mr. Frederickson began to make him
    - 10 -
    feel uneasy in terms of the questions and the look on his face,
    and then out of the blue, according to Mr. Walter," Frederickson
    struck him.         The court stated that it found that the assault had
    occurred      "by    a   preponderance"      and   "frankly   [that   it    was]
    undisputed[,] because Mr. Frederickson admitted that he sucker
    punched Mr. Walter."
    The court revoked Frederickson's supervised release and
    imposed the maximum allowable sentence -- twenty-four months in
    prison followed by eight months of supervised release.
    II.
    On appeal, Frederickson challenges the revocation of his
    supervised release as well as the sentence imposed by the district
    court.     Specifically, he argues that: (1) the district court was
    barred from relying on acquitted conduct to revoke his supervised
    release; (2) even if the acquitted conduct could be used, the
    record does not support a finding of revocation; and (3) the
    sentence imposed is unreasonable.
    A.    Acquitted Conduct as a Basis for Revocation
    Frederickson      contends       that     the   government      was
    collaterally        estopped   from   relying      on   acquitted   conduct   to
    demonstrate that he committed a crime in violation of the terms of
    his supervised release. As noted, prior to the revocation hearing,
    the court conducted a telephonic hearing to consider whether
    acquitted conduct could be used at the revocation hearing.                 Hence,
    - 11 -
    we review this preserved issue of law de novo.           United States v.
    Cruz-Rivera, 
    904 F.3d 63
    , 65 (1st Cir. 2018).
    The Fifth Amendment guarantee against double jeopardy
    bars the government from retrying an individual for the "same"
    offense.      U.S. Const. amend. V.       In Ashe v. Swenson, the Supreme
    Court identified collateral estoppel as an "ingredient" in the
    Fifth Amendment's prohibition on double jeopardy.             
    397 U.S. 436
    ,
    442-46   (1970).      In   effect,    collateral   estoppel    applies     the
    principles of double jeopardy to a subsequent prosecution of a
    "different" offense if, "to secure a conviction[,] the prosecution
    must prevail on an issue the jury necessarily resolved in the
    defendant's favor in the first trial."           Currier v. Virginia, 
    138 S. Ct. 2144
    , 2150 (2018).       For Ashe's collateral estoppel bar to
    apply, "[the court] must be able to say that 'it would have been
    irrational for the jury' in the first trial to acquit without
    finding in the defendant's favor on a fact essential to conviction
    in the second."      
    Id. at 2150
     (quoting Yeager v. United States, 
    557 U.S. 110
    ,    127   (2009)   (Kennedy,    J.,   concurring   in    part   and
    concurring in the judgment)).
    We recognize that there is a broader argument that
    collateral estoppel, as grounded in the Double Jeopardy Clause,
    simply does not apply to revocation proceedings, which often entail
    a loss of liberty but are not criminal prosecutions.               See United
    States v. Correa-Torres, 
    326 F.3d 18
    , 22 (1st Cir. 2003).             Indeed,
    - 12 -
    the Tenth Circuit has stated that a "revocation proceeding . . .
    simply is not a criminal prosecution to which Double Jeopardy
    protections apply." Lynch v. O'Dell, 163 Fed. App'x 704, 707 (10th
    Cir. 2006).        The government attempts, in a perfunctory manner, to
    raise a similar argument.               Even if we excused the government's
    probable waiver of this argument, we would decline to reach it,
    opting instead for affirmance on the narrow ground that collateral
    estoppel, assuming it applies, does not bar the government's use
    of acquitted conduct in this case.2
    Although   we    have    not   previously      addressed   whether
    collateral estoppel prohibits the use of acquitted conduct to
    revoke supervised release, we do not write on a blank page.                     In
    United States v. Watts, the Supreme Court held that "an acquittal
    in   a       criminal   case    does   not   preclude    the   [g]overnment   from
    relitigating an issue when it is presented in a subsequent action
    governed by a lower standard of proof."                 
    519 U.S. 148
    , 156 (1997)
    (per curiam) (quoting Dowling v. United States, 
    493 U.S. 342
    , 349
    (1990)).         In Watts, the police discovered cocaine base and two
    Apparently concerned that we might rule otherwise -- that
    2
    the Double Jeopardy Clause barred the government's use of acquitted
    conduct to seek revocation -- the government, for the first time
    on appeal, invokes the dual sovereignty doctrine to argue that
    double jeopardy does not apply at all because the government sought
    revocation on the basis of Frederickson's simultaneous violation
    of state law. Since we are only assuming that collateral estoppel,
    grounded in the Double Jeopardy Clause, applies here, we need not
    consider the government's dual sovereignty argument.

    loaded guns in the defendant's home.         Id. at 149.    A jury convicted
    the defendant of possession with intent to distribute but acquitted
    on the charge of using a firearm in relation to a drug offense.
    Id. at 149-50.      At sentencing, the district court nevertheless
    found by a preponderance of the evidence that the defendant had
    used the guns in connection with the drug offense and, therefore,
    was subject to an increased sentence.           Id. at 150.
    The Ninth Circuit vacated Watts' sentence and remanded
    for resentencing.      United States v. Watts, 
    67 F.3d 790
    , 796-98
    (9th Cir. 1995).      The circuit court reasoned that, although a
    district court can consider conduct "other than that of which a
    defendant was convicted" in calculating a sentence, it could not
    "reconsider   facts   that   the   jury     necessarily    rejected     by   its
    acquittal of the defendant on another count."             
    Id. at 796
    .
    The Supreme Court reversed, concluding that the Ninth
    Circuit "failed to appreciate the significance of the different
    standards of proof that govern at trial and sentencing," and
    "misunderstood the preclusive effect of an acquittal" when it held
    that the government was barred from relitigating the acquitted gun
    charge at sentencing.      Watts, 
    519 U.S. at 155
    .      The Court explained
    that "it is impossible to know exactly why a jury found a defendant
    not guilty on a certain charge" in the absence of specific factual
    findings.     
    Id.
         An   acquittal,     the   Court   reasoned,   does     not
    establish that the jury rejected any facts or concluded that the
    - 14 -
    defendant was innocent of the charged conduct; it establishes only
    that the government failed to prove an essential element of the
    offense   beyond   a   reasonable    doubt.       
    Id.
          Hence,   the   Court
    concluded, the jury's acquittal on the gun charge did not "preclude
    a finding by a preponderance of the evidence," at sentencing, "that
    the defendant did, in fact, use or carry . . . a weapon . . . in
    connection with a drug offense."             
    Id. at 157
    .     In other words,
    collateral estoppel did not bar the district court's examination
    of the acquitted conduct in light of the lower burden of proof.
    See 
    id.
    The subsequent proceeding here, a revocation hearing, is
    similarly   governed    by   a   lower   standard   of   proof.      To   prove
    Frederickson violated the terms of his supervised release, the
    government needed only to show by a preponderance of the evidence
    that he committed a crime while on supervised release.              See, e.g.,
    United States v. Marino, 
    833 F.3d 1
    , 8 (1st Cir. 2016).              Applying
    the straightforward logic of Watts, we conclude, as have several
    of our sister circuits, that the government's use of acquitted
    conduct to prove assault by a preponderance of the evidence at
    revocation does not violate principles of collateral estoppel.
    See, e.g., United States v. Waller, 616 Fed. App'x 628, 629 (4th
    Cir. 2015) (holding that "[b]ecause the standard of proof is less
    than that required for a criminal conviction," a district court
    may revoke supervised release "even if the defendant is acquitted
    - 15 -
    on criminal charges arising from the same conduct"); Poirier v.
    Doyle, 40 Fed. App'x 211, 213 (7th Cir. 2002) (allowing the
    "revocation of parole [even when] based on criminal conduct for
    which the defendant was acquitted"); see also United States v.
    Teran, 
    98 F.3d 831
    , 836 (5th Cir. 1996) ("Regardless of [the
    defendant's]   acquittal      by   a    jury,   the   revoking   court   had    a
    preponderance of evidence before it to support the finding of th[e]
    probation violation."); United States v. McPherson, 
    814 F. App'x 957
    , 962 (6th Cir. 2020) (similar); Standlee v. Rhay, 
    557 F.2d 1303
    , 1305-06 (9th Cir. 1977) (similar).
    Frederickson nevertheless argues that where, as here,
    the acquitted conduct is the sole basis for a deprivation of
    liberty   rather   than   a   factor      in    determining   the   degree     of
    punishment at sentencing, Watts is inapplicable and collateral
    estoppel should apply.        However, Frederickson misunderstands the
    liberty interests at stake in a revocation hearing.                   Although
    revocation often leads to reimprisonment, and thus "entail[s] a
    loss of freedom and a deprivation of liberty," it is not considered
    an independent criminal prosecution.             Correa-Torres, 
    326 F.3d at 22
    .   Revoking supervised release deprives an individual "only of
    [] conditional liberty" dependent upon observing the restrictions
    imposed by the district court as a condition of release from
    imprisonment for the earlier criminal conviction.                See Morrissey
    v. Brewer, 
    408 U.S. 471
    , 480 (1972).            For that reason, the grounds
    - 16 -
    for revocation "need only be found by a judge under a preponderance
    of the evidence standard, not by a jury beyond a reasonable doubt."
    Johnson v. United States, 
    529 U.S. 694
    , 700 (2000).
    Frederickson also contends that Watts is inapplicable
    because a conclusive finding of self-defense can be gleaned from
    the jury's verdict.     He argues that, because he conceded that he
    assaulted Walter -- though he disputes the severity of the assault
    -- the only explanation for the jury's verdict of not guilty is
    that he prevailed on his theory of self-defense.
    Assuming arguendo that the jury's verdict was based on
    self-defense, which, as we have explained, is impossible to know
    conclusively, see Watts, 
    519 U.S. at 155
    , Frederickson's argument
    would still fail because of the differing burdens of proof.           At
    trial,   Frederickson   initially   was   required   only   to   proffer
    evidence of self-defense that could support a reasonable jury
    finding in his favor.    See United States v. Bello, 
    194 F.3d 18
    , 27
    (1st Cir. 1999) (quoting Mathews v. United States, 
    485 U.S. 58
    , 63
    (1988)).   Having met that low threshold, Frederickson was then
    entitled to the instruction that the court gave, as we quoted in
    Section I(B): that the government had the burden of disproving
    self-defense beyond a reasonable doubt. See United States v. Wilk,
    
    572 F.3d 1229
    , 1237-38 (11th Cir. 2009); Pattern Criminal Jury
    Instruction for the District Courts of the First Circuit § 5.04
    (1997); see also Tr. of Jury Trial Day 3 at 34, United States v.
    - 17 -
    Frederickson, 4:19-cr-40039-LBM-1 (Dec. 1, 2019).                      Applying the
    reasoning of Watts, the verdict for Frederickson only meant that
    the government failed to disprove self-defense beyond a reasonable
    doubt.     The government faced a different, lesser burden at the
    revocation hearing: disproving self-defense by a preponderance of
    the evidence.        See 
    18 U.S.C. § 3583
    (e)(3); see also Watts, 
    519 U.S. at 155-57
    .
    Frederickson       also   invokes       principles    of     fundamental
    fairness to argue that collateral estoppel should apply because
    the court, at the government's request, delayed the revocation
    proceeding until after the criminal trial, allowing the government
    to get the proverbial "second bite at the apple."                      This argument
    misapprehends the dual effect of new criminal conduct committed
    while on supervised release.           In addition to running afoul of a
    criminal    statute,     the    offending       conduct    simultaneously        and
    independently       violates   the    terms    of    release     for    the   initial
    offense.     See United States v. McInnis, 
    429 F.3d 1
    , 5 (1st Cir.
    2005).     The government is entitled to pursue both a new criminal
    conviction and revocation as "part of the penalty for the initial
    offense."     
    Id.
         In doing so, nothing compels the government to
    choose a particular sequence because a violation of supervised
    release does not depend upon whether the violative conduct is the
    subject of a criminal charge or conviction. U.S. Sent'g Guidelines
    Manual § 7B1.1, cmt. 1 (U.S. Sent'g Comm'n 2018) (explaining how
    - 18 -
    to   calculate   the   grade    of    a    supervised     release    violation).
    Practically speaking, the government may seek to secure a criminal
    conviction first because, once it has proven that the defendant
    committed a new crime beyond a reasonable doubt, that conviction
    necessarily demonstrates by a preponderance of the evidence at
    revocation that the defendant violated the terms of supervised
    release by committing a new crime.
    Frederickson    nevertheless         urges     us   to    adopt    the
    reasoning of Commonwealth v. Brown, 
    469 A.2d 1371
     (Pa. 1983), a
    case   that    predates   Watts,      in    which   the    Supreme    Court   of
    Pennsylvania concluded that Pennsylvania law reflects a "clear
    assumption" that when a revocation hearing is delayed until after
    a criminal trial based on the same conduct, "the [government] will
    be bound by the finding of the criminal trial" at the revocation
    hearing.      
    Id. at 1376-78
    .        Pennsylvania law obviously does not
    apply in this case, and Frederickson does not point to any similar
    assumption in federal law.       Indeed, as we have explained, nothing
    prohibits the government from seeking, in no particular order, to
    hold a defendant accountable for both committing a new criminal
    offense and violating a term of supervised release.
    Lastly, Frederickson argues that delaying his revocation
    hearing until after his trial deprived him of procedural due
    process.   Frederickson misunderstands the procedures due him prior
    to revoking his supervised release.           In the context of revocation,
    - 19 -
    procedural due process is satisfied if, in a timely manner, the
    defendant is afforded,
    (A) written notice . . . ; (B) disclosure of
    the evidence against [him]; (C) an opportunity
    to appear, present evidence, and question any
    adverse witness unless the court determines
    that the interest of justice does not require
    the witness to appear; (D) notice of [his]
    right to . . . counsel . . . ; and (E) an
    opportunity to make a statement and present
    any information in mitigation.
    Fed. R. Crim. P. 32.1(b)(2).       Frederickson does not argue that he
    was deprived of any of those procedural protections.           Moreover, at
    Frederickson's revocation hearing, which occurred less than five
    months after the assault on Walter, the court relied, almost
    exclusively, on evidence proffered and examined at trial.                 In
    effect, then, Frederickson received much more than due process
    requires   at   revocation:   he   received   all   of   the   due   process
    protections that come hand-in-hand with a criminal trial on the
    merits.    Frederickson's due process argument fails.
    B.    Sufficiency of the Evidence
    Frederickson contends that even if acquitted conduct can
    be used to revoke supervised release, the evidence presented by
    the government was insufficient to prove, by a preponderance of
    the evidence, that he committed an assault and was not acting in
    self-defense.     We review a district court's decision to revoke
    supervised release for abuse of discretion and factual findings
    supporting that decision for clear error.           Oquendo-Rivera, 586
    - 20 -
    F.3d at 66-67.    As we have previously recognized, sufficiency
    challenges to supervised release revocations are "notoriously hard
    to win," because (1) we must view the evidence in the light most
    favorable to the government, (2) the district court's choice among
    competing, yet plausible, inferences from the evidence does not
    amount to clear error, and (3) credibility determinations are
    primarily for the district court.        Marino, 833 F.3d at 8.
    The district court concluded that Frederickson did not
    act in lawful self-defense when he assaulted Walter because "[e]ven
    if   [Frederickson]   believed    that     Paul    Walter   unlawfully     had
    physical contact with him, [Frederickson] used more force than
    appeared reasonably necessary in the circumstances."             Frederickson
    contends that the record does not support the severe, protracted
    assault   described   by    the   court.          Frederickson    points   to
    inconsistencies   between     Walter's      testimony,      Officer   Skal's
    testimony, and Walter's medical records.            He also questions the
    district court's reluctance to credit his claim of sexual assault.
    At trial, Walter testified that the assault began with
    a closed fist punch delivered by Frederickson to Walter's left
    eye.   He then described the ensuing altercation as follows:
    Mr. Frederickson grabbed me in a front
    chokehold, slammed my head against the wall,
    the table, and eventually to the floor. . . .
    As I was kicking the door and I still had air
    to speak, I was screaming for help, kicking
    the door, the floors, walls, in an attempt to
    make any noise so somebody could hear
    - 21 -
    me. . . . I felt a lot of pain and kind of,
    I guess, shock. . . . I was being strangled
    against my will . . . . [I said] You're going
    to kill me. . . . I told [Officer Skal] "Get
    him off me.    He's going to kill me." . . .
    Officer Skal left the bathroom. . . . At this
    point I had pretty much given up that anybody
    was going to be in the office. . . . My body
    began to not tense up as much, and I kind of
    accepted that I might be breathing my last
    breath underneath that toilet. . . .     Some
    time later [Officer Skal] came [back] . . . .
    Mr. Frederickson was still on top of me.
    Officer Skal told him to "Get off him," and
    Mr. Frederickson eventually complied with
    that. . . .     [After Frederickson left,] I
    attempted to get up . . . . I got out towards
    the lobby door, crawling. I then attempted to
    stand up, and I fell over and slammed my head
    against the wall in the lobby.
    Walter testified that when he went to the hospital, he
    was experiencing severe symptoms:
    [His] face felt extremely swollen . . . [his]
    jaw [felt] broken. [He] couldn't really open
    [his] left eye.     [His] leg was extremely
    strained. [He] couldn't really walk. [His]
    neck was strained . . . . [He] had a cut in
    . . . [his] back [and] head and swelling of
    the back of [his] head.
    He further testified that he told the doctors that he had sustained
    a punch to the face with a closed fist, he was strangled, his leg
    hurt, his face was swollen, and he had a headache.
    Frederickson   points   to   notes   in   the   emergency   room
    doctor's medical report indicating that Walter was negative for
    neck pain, skin wounds, dizziness, trouble swallowing, nosebleeds,
    nausea, change in vision, and headaches, as support for his
    - 22 -
    argument that the assault was not as severe as Walter claimed at
    trial.   Although there were small discrepancies in the report vis-
    á-vis Walter's testimony, the medical records in their totality
    support Walter's description of a severe assault.                     The records
    identify Walter's reason for visiting the emergency room as an
    "assault[] while at work . . . in locked bathroom, [patient] was
    punched to [left] side of face, slammed down on the ground, hit
    [right] side of face, strangled [for] 'a couple minutes.'"                     The
    records further state that Walter presented as "assaulted by
    client, was choked and struck with fist on left jaw," reported
    pain in his jaw and leg, was positive for facial swelling, and
    contusions of the head and face.                  Moreover, the court placed
    considerable weight on the photographs of Walter's injuries and of
    blood on the wall after the altercation.              The court also found the
    corroborating testimony of Officer Skal "utterly credible."
    Officer       Skal's       testimony    did   corroborate       Walter's
    description of the assault in all major respects.                  Specifically,
    Officer Skal testified that he heard thumping in the bathroom,
    opened the bathroom door, saw Frederickson on top of and choking
    Walter, perceived the situation as "extremely dangerous," and
    immediately retreated to call 911.                The assault then continued
    while Officer Skal left the bathroom, called 911, reported the
    assault,   and   entered       the    bathroom    a   second   time   to   observe
    Frederickson     still    on    top    of   Walter.      Officer   Skal     further
    - 23 -
    testified    --    and   Officer   Garlick   later   corroborated   --   that
    Frederickson had no visible injuries following the altercation.
    Frederickson points to several inconsistencies in the
    testimony of Walter and Officer Skal: (1) Walter said the reason
    Officer Skal entered the bathroom was that Walter was screaming
    for help and kicking the door, floor, and wall, while Officer Skal
    testified that it was because he heard a "thumping sound, almost
    like a bowling ball hitting a marble floor"; (2) Walter testified
    that his head was under the toilet when Officer Skal entered the
    bathroom, while Officer Skal testified that Walter's head was
    "positioned almost under the sink"; (3) Walter testified that he
    and Frederickson were in the same spot when Officer Skal returned
    the second time, while Officer Skal testified that "[t]hey were
    not . . . [and Walter's] body was a little bit more upright"; and
    (4) Walter testified that he got out of the bathroom by crawling
    out of the door and into the lobby covered in blood, while Officer
    Skal testified that he helped Walter out of the bathroom.
    The minor inconsistencies cited by Frederickson do not
    undermine the court's determination that the combined testimony of
    Walter and Officer Skal supported Walter's version of events.            The
    court explained that Officer Skal "was there.            He heard what was
    happening.    He opened the door twice, and both times saw [Mr.]
    Walter being assaulted in a manner consistent with Mr. Walter's
    testimony."       As we have explained, credibility determinations are
    - 24 -
    primarily for the district court, Marino, 833 F.3d at 8, and the
    court    resolved   the    inconsistencies        cited    by    Frederickson    by
    explaining, "I think both Officer Skal and Walter [we]re [] in
    shock on some level, and so the fact that they might not remember
    certain details about the way the legs were and the arms were
    flailing during the assault, that in the [c]ourt's view, is
    understandable."
    Frederickson      also    contends     that    the   court   erred   in
    doubting his allegation of sexual assault primarily because he
    failed to report the assault.              Frederickson faults the court for
    "speculating" and "prescrib[ing]" how he should have processed the
    assault.    At the revocation hearing, the court concluded that it
    could discern no reason for Frederickson's failure to tell Officer
    Skal or Officer Garlick that he was sexually assaulted, or to
    otherwise report Walter for such a serious offense. As we describe
    in   more    detail       when   discussing         the     reasonableness       of
    Frederickson's      sentence,        the     court's      skepticism     regarding
    Frederickson's      alleged   failure       to   report    was   but   one   factor
    supporting its conclusion that Frederickson lacked credibility.3
    3 See, e.g., Reyes v. Mitchell, 
    2020 WL 1550238
    , No. 18-40147-
    WGY, slip op. at 10-13 (D. Mass. Apr. 1, 2020) (explaining that a
    delay or failure to report a sexual assault can be used to impeach
    a witness' credibility). That is not to say, however, that a delay
    or failure to report should be viewed uncritically as the sole
    basis for disbelieving a victim of sexual assault.          Indeed,
    research shows that sexual assault victims "experience a range of
    conduct, suffer a range of harms, [] respond [to assault] in
    - 25 -
    Viewing the evidence in the light most favorable to the
    government, as we must, we conclude that the district court's
    finding that Frederickson assaulted Walter in excess of the bounds
    of lawful self-defense is not clearly erroneous and, therefore,
    the court did not abuse its discretion in revoking Frederickson's
    supervised release.
    C.   Reasonableness of the Sentence
    Frederickson claims that the court erred in imposing an
    unreasonably long sentence based on improper sentencing factors
    and without resolving critical factual conflicts.     We review a
    district court's chosen sentence for abuse of discretion.   United
    States v. Clogston, 
    662 F.3d 588
    , 590 (1st Cir. 2011).         The
    "touchstone" of our review is reasonableness, which may involve
    both procedural and substantive inquiries.   
    Id.
    In assessing procedural unreasonableness, we ask whether
    the court made any procedural errors during the sentencing phase,
    such as "failing to calculate (or improperly calculating) the
    Guidelines range, treating the Guidelines as mandatory, failing to
    consider the 
    18 U.S.C. § 3553
    (a) factors, selecting a sentence
    divergent ways," and may choose not to report or to delay reporting
    because they feel responsible, embarrassed, ashamed, or for a
    variety of other reasons. See, e.g., Jamie R. Abrams, The #METOO
    Movement: An Invitation for Feminist Critique of the Rape Crisis
    Framing, 
    52 U. Rich. L. Rev. 749
    , 772-776 (May 2018); see also
    Kathryn M. Stanchi, The Paradox of the Fresh Complaint Rule, 37
    B.C.L.R. 441, 459-462 (May 1996).
    - 26 -
    based on clearly erroneous facts, or failing to adequately explain
    the chosen sentence -- including an explanation for any deviation
    from the Guidelines range."         United States v. Politano, 
    522 F.3d 69
    , 72 (1st Cir. 2008) (quoting Gall v. United States, 
    522 U.S. 38
    , 51 (2007)).      If no procedural errors have been committed, and
    the appellant is arguing substantive unreasonableness, we ask
    whether the district court provided a "plausible" explanation for
    its sentencing determination and whether, based on the totality of
    the circumstances, the overall result is "defensible."                    United
    States v. Innarelli, 
    524 F.3d 286
    , 292 (1st Cir. 2008).
    Frederickson   says    that    he   is    challenging     only   the
    substantive reasonableness of his sentence but, as the government
    notes, two of his arguments -- that the court failed to consider
    all appropriate sentencing factors and failed to resolve critical
    factual issues -- raise procedural concerns.                See Politano, 
    522 F.3d at 72
    .      Hence, we begin our review of the alleged procedural
    errors with a brief overview of Frederickson's sentencing hearing.
    The court began its sentencing explanation by stating
    that the applicable guidelines range of twelve to eighteen months
    in   prison    was   insufficient,    and    that      Frederickson's    conduct
    warranted an upward variance to the maximum allowable sentence.
    The court remarked that it viewed even that sentence -- twenty-
    four months in prison and eight months on supervised release -- to
    be inadequate, but the sentence could not exceed the statutory
    - 27 -
    maximum.   The court proceeded to explain that it had considered
    all relevant factors, including the nature and circumstances of
    the violation as well as Frederickson's criminal history and
    personal characteristics, and determined that a statutory maximum
    sentence was not greater than necessary.
    The court outlined the two primary goals served by its
    sentence: general deterrence and public protection.       The court
    explained that a severe sentence was warranted to deter others
    from assaulting members of the U.S. Probation Office while on
    supervised release, which is designed to help federal prisoners
    reintegrate into society. The court also noted that Frederickson's
    history of violent crime and     his   two previous violations of
    supervised release within the prior year -- one for assaulting his
    parents and one for participating in an unarmed robbery -- made
    him a "menace" and a danger to the public.   According to the court,
    by committing yet another offense while on supervised release,
    Frederickson "thumbed [his] nose at the [c]ourt, at Probation, and
    at law enforcement" and demonstrated that he could not be trusted
    to comply with the terms of continued supervised release.
    Frederickson contends that the court's focus on those
    two goals demonstrates that the sentence was improperly driven by
    a vindictive motive and that the court failed to take mitigating
    factors into account. We disagree. Frederickson points to nothing
    in the court's sentencing colloquy that demonstrates an improper
    - 28 -
    motive.   See United States v. Pimienta-Redondo, 
    874 F.2d 9
    , 13
    (1st Cir. 1989) ("Absent proof of an improper motive -- or some
    sound reason to suspect the existence of one -- no reasonable
    apprehension of vindictiveness can flourish.").         To the contrary,
    the court explained that it had considered each of the factors
    prescribed by statute for determining the appropriate sentence for
    a violation of supervised release, which include "the history and
    characteristics of the offender; the nature and circumstances of
    the new offense; the need to deter further criminal conduct; and
    the need to protect the community from the offender's penchant for
    criminal behavior."     United States v. Márquez-García, 
    862 F.3d 143
    , 145 (1st Cir. 2017) (citations omitted); see also 
    18 U.S.C. §§ 3583
    (e), 3553(a).4
    The court further explained that it had reviewed all of
    the   information   submitted   by   both   parties,   including   factual
    objections and legal arguments, Walter's victim impact statement,
    Frederickson's supervised release violation report, the parties'
    sentencing memos, and the letters of support from Fredrickson's
    family and friends.      The court even remarked that the letters
    submitted on Frederickson's behalf, which, according to the court,
    portrayed someone very different from the person described in the

    sentencing factors set forth in § 3553(a) in determining whether

    violation report, provided a glimmer of hope that Frederickson may
    receive familial support upon his release from prison.
    That the court chose to highlight only two factors in
    more detail     -- deterrence and public protection               --    does not
    undermine the "significant weight" we afford a court's statements
    regarding the factors and information it considered at sentencing.
    Márquez-García, 862 F.3d at 145 ("Although a sentencing court must
    consider each of the factors that section 3583(e) identifies, the
    court is not obliged to address these factors 'one by one, in some
    sort   of    rote     incantation    when     explicating     its      sentencing
    decision.'     Rather, the court need only identify the principal
    factors upon which it relies to reach its sentencing decision."
    (citations omitted) (quoting United States v. Dixon, 
    449 F.3d 194
    ,
    205 (1st Cir. 2006)));      United States v. Santiago-Rivera, 
    744 F.3d 229
    , 233 (1st Cir. 2014) ("[T]he sentencing judge explicitly noted
    that he had considered all of the section 3553(a) factors.                     Such
    a statement is entitled to significant weight . . . .").
    Frederickson    also    claims     that   the   court     failed    to
    resolve     factual   conflicts     regarding    the   impetus,      nature,    and
    extent of the assault. According to Frederickson, the court failed
    to adequately explain which version of events it found credible
    and, therefore, the lengthy sentence it imposed is not supportable.
    Here, too, we disagree.        Immediately prior to sentencing, while
    revoking Frederickson's supervised release, the court explained
    - 30 -
    that it found the testimony of Walter "credible by a preponderance
    of the evidence" and the testimony of Officer Skal "utterly
    credible."         It    further     concluded       that   Frederickson's         conduct
    reflected that he had a "serious issue, a serious problem" and
    that he did not act in lawful self-defense when he assaulted
    Walter.
    As Frederickson points out, the court's statements do
    not include an explicit finding that Frederickson was not credible
    or   that   he     lied    about     being    sexually       assaulted       by    Walter.
    Nevertheless, we read the court's findings as a rejection of
    Frederickson's version of events.                   As noted, the court began its
    findings     by         expressing     considerable          skepticism        regarding
    Frederickson's           testimony,     discerning          "no     reason        for   Mr.
    Frederickson not to say to Officer Skal or to anyone that night
    that . . . 'I was sexually assaulted. . . . I'm on top of him
    because he assaulted me.'"             The court further commented that the
    evidence showed that "Mr. Frederickson remained without any sort
    of responsiveness and didn't mention to Officer Garlick, who
    apparently knows the family, 'Officer Garlick, I was sexually
    assaulted' and talk to him, tell him that.                        Nothing.     There was
    nothing that was mentioned."                  The court went on to carefully
    explain     how,    in     its     view,     virtually      all     of   the      evidence
    corroborated Walter's version of events.                          It explicitly found
    - 31 -
    Walter's      testimony,     as    corroborated      by    the    only        eyewitness,
    Officer Skal, credible and supportable.
    The court further described Frederickson's conduct as
    "gravely      concerning,"    and    it    concluded       that   Frederickson         had
    proven "that [he] cannot be trusted to comply with the terms and
    conditions of supervision."              The court stated that "if [it] could
    order [him] to be locked up for longer, [it] would" because "[t]he
    public   deserves     that[,]      Paul    Walter    deserves      that[,]       [e]very
    probation officer deserves that."                 The court warned Frederickson
    that "if you come before this [c]ourt ever again and if you lay
    hands    on   one   other    person,      you     will    not    get    probation      and
    interactive journaling.            No.    You will get the sentence that you
    deserve."5
    Juxtapose those statements with the court's praise of
    Walter's work as a Probation intern "working with [Frederickson,]
    supervising      [his]      drug    testing,"       "engaging          with    [him]   in
    interactive journaling," and "working with [him] to help [him]
    integrate into society, become law-abiding."                       Indeed, speaking
    directly to Walter, the court said:
    You must not turn away from a career in
    criminal justice based on this hideous
    experience. . . . You became a victim because
    of your service, because of your courage, and
    5 Interactive journaling is a "cognitive behavioral treatment
    approach" in which a member of the Probation Office assists ex-
    convicts with journaling to help "[i]dentify [their] thoughts and
    actions leading to behaviors."
    - 32 -
    I hope you redouble your efforts.     I trust
    that you will have support along the way. You
    did not deserve this, sir, but thank you for
    your service.
    In short, the court's statements reflect an adoption of
    Walter's version of events, which necessarily entails a rejection
    of Frederickson's allegation of sexual assault.                     Contrary to
    Frederickson's assertions, the court did not leave unresolved a
    critical factual dispute between Walter and Frederickson and,
    thus,     we    discern     no      procedural      unreasonableness       with
    Frederickson's sentence.
    Turning to substantive reasonableness, we must consider
    whether   the   challenged       sentence   falls   within    the    "expansive
    'universe of reasonable sentencing outcomes.'"               United States v.
    Díaz-Lugo, 
    963 F.3d 145
    , 157 (1st Cir. 2020) (quoting Clogston,
    
    662 F.3d at 592
    ).         In doing so, we may not substitute our own
    judgment for the judgment of the sentencing court.                   
    Id.
       "[A]s
    long as the sentencing court has mulled all the relevant factors,"
    and reached a defensible result, Frederickson cannot prevail by
    merely complaining about the court's assessment of those factors.
    
    Id.
    As explained above, the court considered each of the
    statutory factors, see 
    18 U.S.C. §§ 3583
    (e), 3553(a), finding that
    Frederickson committed a serious violent offense, had a proclivity
    for recidivism, and was a danger to the public.           The court weighed
    - 33 -
    the last two factors the heaviest, concluding that Frederickson
    was a menace and that his two prior supervised release violations
    demonstrated a lack of appreciation for the terms of supervised
    release and the judicial system as a whole.                     The circumstances of
    Frederickson's prior violations support the court's conclusion.
    In March 2018, Frederickson pled guilty to assaulting
    both of his parents. Following an argument, Frederickson violently
    pushed them both to the ground and caused his father to flee the
    home.   His parents were both granted emergency restraining orders.
    Frederickson was found in violation of his supervised release and
    sentenced    to   time     served,     followed      by    twenty-four         months    of
    supervised release.
    Frederickson        was   found    in    violation         of    supervised
    release again in October 2018.           While responding to a report of an
    unarmed     robbery   of    a    woman   in    Worcester,         a    police    officer
    identified and pulled over a suspected vehicle.                       Frederickson was
    driving the vehicle, and the woman's purse, which contained a
    bottle of unspecified pills, was found inside.                        He was sentenced
    to   four   months'      imprisonment,        followed      by    twelve      months    of
    supervised release.
    Given the violent circumstances of this offense and the
    court's explicit consideration of Frederickson's prior supervised
    release     violations,     we    conclude     that       the    court       applied    the
    appropriate sentencing factors, provided a plausible rationale for
    - 34 -
    its judgment, and imposed a defensible sentence based on its
    supportable   view   of   the   facts.     Frederickson's   sentence   was
    substantively reasonable.
    Affirmed.
    - DISSENTING OPINION FOLLOWS -
    - 35 -
    BARRON,    Circuit   Judge,       dissenting.        The    majority
    concludes that the District Court implicitly found that Daniel
    Frederickson was not telling the truth about what had been done to
    him right before he violently lashed out at the probation officer
    who was overseeing his drug test, see Slip Op. at 32, and that the
    District Court relied on that implicit finding to justify its
    decision to revoke Frederickson's supervised release in full, see
    
    id. at 32-34
    .    The majority relies for this conclusion chiefly on
    the passages in the District Court's opinion that praise without
    qualification the probation officer for his service, see 
    id. at 34
    , and that question why Frederickson did not tell anyone about
    his allegation that the officer assaulted him right beforehand,
    see 
    id. at 33
    .   But, while those statements do provide some support
    for   the   majority's    characterization      of   the     District   Court's
    reasoning, other statements in the District Court's opinion point
    against it and prevent me from signing on to the majority's ruling.
    For starters, the District Court stated in describing
    the basis for finding that Frederickson had violated the terms of
    his supervised release that "[e]ven if [he] believed that [the
    officer] unlawfully had physical contact with him, [he] used more
    force than appeared reasonably necessary in the circumstances."
    (emphasis    added).      Far    from    rejecting     the    credibility    of
    Frederickson's    claim   that   he     had   been   assaulted    first,    that
    statement expressly concludes that his manner of attacking the
    - 36 -
    officer was itself so violent that it constituted a criminal
    assault no matter what had occurred beforehand.
    Several other statements by the District Court then go
    on   to   reinforce    the    impression       that     it    was     focused       on   the
    especially violent nature of Frederickson's attack, rather than
    whether he had been victimized in his own right first.                                    The
    District Court states at one point, for example, that while
    Frederickson       "testified      that        [the        officer]      touched         him
    inappropriately one time at the beginning of the encounter," there
    was "[n]o testimony of any other unlawful contact or that [the
    officer] responded to the defendant's punch with ongoing unlawful
    force or contact, and yet [] Frederickson's assault on [the
    officer] continued."          (emphasis added).            The District Court then
    emphasizes    at    another     point     that,       in     its    view,      there      was
    "additional    proof    that    more     force    was       used    than    necessary,"
    (emphasis added), namely the extent of the officer's injuries as
    documented    by    photographs,        his    testimony,          and   his    hospital
    records.
    Further,     when      the        District        Court      states          that
    Frederickson's attack on the officer was "out of the blue," it
    qualifies that assertion by noting that such a description of the
    event was "according to" the officer.                      It thus appears to be
    relying on a fact that it determined was "frankly . . . undisputed"
    --   specifically      that    "Frederickson          admitted       that      he   sucker
    - 37 -
    punched" the officer -- and that in and of itself hardly undermines
    Frederickson's account of what had been done to him. Additionally,
    when the District Court states that it "f[ound] [the officer's]
    testimony about the assault credible by a preponderance of the
    evidence,"   it    refers     specifically      to     the     violence       that
    Frederickson used in attacking the officer and not to what had
    transpired just before.
    Finally, by the time of the revocation decision, a jury
    had already acquitted Frederickson of the assault at issue after
    it had been instructed that the government needed to prove beyond
    a reasonable doubt that Frederickson was not acting in self-defense
    and after it had heard Frederickson testify that he had been
    sexually assaulted in the restroom.           I agree that the District
    Court was not bound by that jury's verdict, see United States v.
    Paneto, 
    661 F.3d 709
    , 715 (1st Cir. 2011), and there are certainly
    grounds to doubt Frederickson's account.            But, I am still hesitant
    to conclude that the District Court intended to reject without
    ever expressly saying so a seeming premise of that jury’s verdict
    -- namely, that Frederickson was credible in contending that he
    had been sexually assaulted immediately prior to attacking the
    officer.     See   Dimick   v.   Schiedt,     
    293 U.S. 474
    ,   486   (1935)
    ("Maintenance of the jury as a fact-finding body is of such
    importance   and   occupies   so   firm   a   place    in    our    history   and
    jurisprudence that any seeming curtailment of the right to a jury
    - 38 -
    trial   should     be   scrutinized     with   the   utmost   care.");     United
    States v. Bell, 
    808 F.3d 926
    , 928 (D.C. Cir. 2015) (Kavanaugh, J.,
    concurring in the denial of petitions for rehearing en banc)
    ("[F]ederal district judges have power in individual cases to
    disclaim reliance on acquitted or uncharged conduct."); United
    States v. McReynolds, 
    964 F.3d 555
    , 565 (6th Cir. 2020) (explaining
    that the fact that a district court may rely on acquitted conduct
    at sentencing "is not a greenlight for the district court to do
    whatever it wants at sentencing regardless of the jury's verdict
    and without explanation"); cf. United States v. Lombard, 
    102 F.3d 1
    , 5 (1st Cir. 1996) ("Certainly situations exist where the
    sentencing court might persuasively explain the use of acquitted
    conduct.").
    Thus, for these reasons, unlike the majority, I am
    uncertain whether the District Court settled on the complete
    revocation    of    Frederickson's       supervised     release   because     it
    disbelieved his story altogether, because it believed his claim
    that he had been sexually assaulted while taking the drug test but
    concluded that his violent response was grossly disproportionate,
    or because it thought that it was so evident that his violent
    conduct was of a kind that warranted such a revocation (at least
    given the evidence of his past violence while on supervised
    release) that there was no need to make a finding one way or the
    other   as   to    whether   he   had    been    assaulted    first   or    not.
    - 39 -
    Accordingly, in my view the proper course is to vacate and remand
    the District Court's revocation decision so that it may clarify
    the rationale for it and thereby ensure that Frederickson receives
    the kind of explanation to which he is entitled for this severe
    punishment.   See United States v. Ofray-Campos, 
    534 F.3d 1
    , 43
    (1st Cir. 2008) (finding procedural error where the district
    court's explanation for a significant upward variance was "neither
    sufficiently particularized nor compelling to survive . . . review
    for reasonableness").   I therefore respectfully dissent.
