    THOMPSON, Circuit Judge.      The case we now confront
    presents a sad and recurring scenario, one we see play out on the
    national stage all too often.       While the facts among these cases
    may differ in varying degrees, the legal outcome is often the
    same:       enter stage right, the legal principles of supervisory
    liability, failure to train, and yes, unsurprisingly, qualified
    immunity,1 too.
    On June 14, 2013, Massachusetts State Trooper Stephen
    Walker      ("Walker")   pepper-sprayed,   shot,   and   killed   Wilfredo
    Justiniano, Jr. on the side of a highway.           Damaris Justiniano,2
    Justiniano's sister and the personal representative of his estate,
    brought a wrongful death and civil rights suit against both Walker
    and the Superintendent of the Massachusetts State Police, Colonel
    Timothy Alben ("Alben"), alleging that Walker used excessive force
    against Justiniano in violation of his constitutional rights, and
    that Alben should be brought to bear for that violation as well
    via supervisory liability (specifically, failure to train).           The
    district court dismissed the claims against Alben for failure to
    state a claim, and later, the magistrate judge granted summary

    judgment for Walker based on the qualified immunity doctrine.3
    Justiniano appealed.
    In the wake of the oral argument we heard on that appeal,
    a new issue bubbled up: Justiniano's motion to vacate the summary-
    judgment   grant   based    on    newly   discovered   evidence   that,   in
    Justiniano's view, further supported the argument that summary
    judgment for Walker was inappropriate and he was not entitled to
    qualified immunity.        The magistrate judge declined Justiniano's
    invitation to set aside the judgment, and Justiniano appealed that,
    too.
    Having scoured the record and carefully reviewed the
    issues in this consolidated appeal, we affirm each of the lower
    court's judgments.
    BACKGROUND
    We start with the facts, which we present in the light
    most favorable to Justiniano; as we do so, we draw all supportable
    inferences in his favor.         See, e.g., Rivera-Corraliza v. Morales,
    
    794 F.3d 208
    , 210 (1st Cir. 2015) (citing Soto–Padró v. Pub. Bldgs.
    Auth., 
    675 F.3d 1
    , 2, 5 (1st Cir. 2012)).        We'll first recount the
    3As a heads-up, note that the district court judge entered
    judgment on the motion to dismiss and the magistrate judge -- who,
    by agreement of the parties and in accordance with 
    28 U.S.C. § 636
    (c) and Rule 73(b) of the Federal Rules of Civil Procedure,
    thereafter handled the case on his own -- entered judgment on the
    summary-judgment motion, as well as the subsequent motion to vacate
    that judgment.
    - 4 -
    facts of the incident itself -- the unfortunate turn of events
    that sparked this litigation in the first place -- before shifting
    to all of the procedural history.             As is usually the case in the
    summary-judgment context, the parties dispute a number of facts,
    particularly     those      regarding       what     happened    after     Walker
    encountered Justiniano on the side of the highway.                       But what
    brought Walker to the scene is undisputed, and that's where we
    begin.
    On that morning in June 2013, Justiniano, a forty-one-
    year-old     Hispanic    man    who   had    been    diagnosed   with    paranoid
    schizophrenia, was driving north on Route 28 near the Milton/Quincy
    line in Massachusetts.           A driver behind him, Karen Kyriakides
    ("Kyriakides"), noticed that he was driving erratically.                     When
    Justiniano    pulled    over,    Kyriakides     (a    good   Samaritan    indeed)
    stopped as well and, concerned about Justiniano's well-being, went
    over to his car to check on him.            Noticing that Justiniano was out
    of sorts -- confused, distraught, and not speaking intelligibly -
    - she returned to her car and called 911.                 The record does not
    include a transcript of the 911 call, but Kyriakides remembers
    telling the dispatcher a man "needed help" but she "didn't know
    what was going on with [him], so they needed to come out and see
    what   was   going   on."       Kyriakides     indicated     that,   because   of
    Justiniano's erratic behavior, she was scared for Justiniano,
    herself, and anyone else driving by.
    - 5 -
    Meanwhile,   at   the   nearby   state   police   barracks   in
    Milton, Walker's 7:00 a.m. day shift was getting underway when
    Kyriakides' 911 call came in.     The desk officer who took the call
    told Walker about "a possible medical emergency" on Route 28;
    around 8:00 a.m., Walker set out for the scene.             When Walker
    arrived, he saw Justiniano standing near his car.       Walker radioed
    for backup, then parked behind Justiniano's car and left his
    emergency lights flashing before exiting his vehicle to see what
    was going on.
    The details of what followed are hotly contested.
    According to Walker, Justiniano told Walker that he
    (Justiniano) was an undercover cop and Walker was going to have to
    kill Justiniano.4   Justiniano, moving toward Walker, next told
    Walker that if Walker didn't kill him (Justiniano), he would kill
    Walker -- and he repeated this throughout the encounter.               At
    various points during their standoff, Walker attempted to calm
    Justiniano down verbally and through gestures.          Three civilian
    witnesses on or near the scene -- Kyriakides, Jo-Ann Silva-Winbush,
    and Shannon MacKeen -- testified that they saw Walker using hand
    gestures meant to stop Justiniano from moving towards Walker and/or
    to calm Justiniano down; none of the witnesses indicated that
    Justiniano complied.    Throughout this part of their encounter,
    4  None of the other witnesses could hear what was being said
    by Justiniano or Walker.
    - 6 -
    Walker and Justiniano stood about fourteen to twenty feet apart
    from one another.            Walker says Justiniano, while approaching
    Walker, was holding a ballpoint pen much like someone would hold
    a knife, still talking about killing Walker.5               In response, Walker
    began to retreat -- Kyriakides testified she saw Walker taking
    steps       backward    toward    the    highway;    Silva-Winbush   said     Walker
    "jumped in front of her car" so she came to a stop, then watched
    him back up into the road further.                Walker also told Justiniano to
    stop        advancing    toward    him.        Silva-Winbush      explained    that
    Justiniano was "coming after" or "lunging for" Walker at this
    point, and Walker "put his hand up" to indicate "stop" and "[s]tay
    there" to Justiniano with his hand palm-out towards Justiniano.
    Kyriakides testified that she saw Justiniano "getting closer to
    the trooper," and "look[ing] like he was ready to jump on [Walker]"
    and, eventually, "lung[ing]" at him.
    Asserting    that        "it   was   immediately    apparent    that
    Wilfredo Justiniano was having a mental health crisis," Justiniano
    urges a different version of these events, disputing in particular
    that Justiniano was holding a pen and threatening to kill Walker.
    Specifically, Justiniano highlights that Silva-Winbush and MacKeen
    stated they could not see anything in Justiniano's hands, while
    Kyriakides said she noticed Justiniano placed an object (she didn't
    5
    No other witness testified to seeing Justiniano holding a
    pen (though a pen was found at the scene).
    - 7 -
    see what it was) on the ground before Walker arrived, and, when he
    moved towards Walker, it was with his arms out and palms open.                      As
    for the threats Walker said Justiniano made, Justiniano asserts
    that   the    idea      that   Justiniano        was    uttering     comprehensible
    communications does not jibe with Kyriakides' testimony that, when
    she spoke with Justiniano moments before Walker's arrival, he was
    not speaking an intelligible language.
    In   any    event,      whether     Justiniano      was   unarmed     and
    speaking     incoherently,      or      wielding   a    pen   like     a   knife   and
    threatening Walker, it is undisputed that Justiniano kept moving
    forward (though the nature of this precise movement is very
    debated, as we'll discuss later), so Walker, keeping a distance of
    about fourteen feet between them, next resorted to his pepper
    spray, spraying Justiniano twice in the face. Kyriakides explained
    that Walker appeared to spray Justiniano after Justiniano lunged
    at him, but she didn't actually see either spraying take place.
    Silva-Winbush,       however,     did    see   Walker    spray     Justiniano,     and
    observed that neither spraying seemed to "bother [Justiniano],"
    who "shook it off."
    According to Walker, the wind blew some of the second
    spray back into Walker's eyes, compromising his vision.                        After
    being sprayed that second time, Justiniano moved towards Walker
    and closed the distance between them.                  Kyriakides testified that
    Justiniano was "charg[ing] at" Walker, and Silva-Winbush testified
    - 8 -
    that Justiniano "came after" Walker at that point, "really mad"
    and "ready to fight," despite Walker again holding up his hand,
    gesturing for Justiniano to stop, and continuing to back up into
    the highway.
    As best we can tell from the excerpts of her deposition
    in the record, MacKeen was driving by the scene around this time,
    "stopp[ing] a little bit when [she] realized what was going on."
    She noted seeing Walker's hand on his gun and Justiniano dipping
    his shoulder, leading to Walker "pull[ing] the weapon" -- the
    weapon being his gun, which she saw, before driving away; then she
    heard the shot.   She explained that, while they'd been "basically
    stationary" when she first saw Walker and Justiniano, Justiniano
    was swaying and pacing before taking some steps towards Walker,
    then dipping his shoulder down "like he might attack" Walker.
    MacKeen also indicated that Walker had put his hands in front of
    him, gesturing "to make [Justiniano] stand down, stop moving[,]"
    and Walker took "one big step back" before Justiniano had dipped
    his shoulder.   At no point does MacKeen mention pepper spray.
    When Justiniano was about four to seven feet away from
    Walker, Walker unholstered his firearm and fired two shots from
    his hip.   One shot hit Justiniano in his left forearm, the other
    in his chest. Walker says that Justiniano, after being shot, tried
    to get up, so Walker pushed him back to the ground with his foot.
    A backup officer, (Joseph Durning) arrived, and he and Walker
    - 9 -
    struggled to handcuff Justiniano; Durning, concerned Justiniano
    might       have   a   weapon,   pepper-sprayed   Justiniano.   Eventually,
    Walker, Durning, other officers, and firefighters were able to
    subdue and handcuff Justiniano, who was then placed on a stretcher.
    From there, he was transported to Milton Hospital, where he was
    later pronounced dead.
    On April 14, 2015, Justiniano filed suit against Walker
    and Alben in the United States District Court for the District of
    Massachusetts.6         Relevant to this appeal, under 
    42 U.S.C. § 1983
    ,
    the complaint alleged that Walker's actions violated Justiniano's
    right to be free from excessive force (Count 1), and that Alben,
    as Walker's supervisor, was deliberately indifferent in failing to
    train Massachusetts State Troopers on how to interact with mentally
    ill individuals (thus, he alleged, putting Alben on the liability
    hook for Walker's actions) (Count 3).7              More on the details of
    6
    The complaint alleged four counts, but, on appeal,
    Justiniano is pursuing the dismissal of Counts 1 and 3 only. The
    curious reader can note that the counts not being chased down in
    today's appeal were wrongful death claims against Walker (Count 2)
    and Alben (Count 4).
    7
    Quick pause to observe that both the complaint and summary-
    judgment phase focused on the shooting as the excessive force, but
    in the motion to vacate (which we'll discuss in a bit) and now
    before us on appeal, Justiniano switched gears and advances the
    first use of the pepper spray as the excessive force. It's unclear
    why. Because of the analytical route we'll be taking on our way
    to resolving this case, we can assume (without deciding) that this
    switch-up does not constitute waiver. Thus it is not necessary
    for us to comment or consider this further.
    - 10 -
    these allegations down the line.
    As we already previewed, these claims were dismissed,
    albeit at different stages of the litigation timeline.          First, on
    September 22, 2016, the district court, adopting a magistrate
    judge's   report   and   recommendation   ("R&R")    over     Justiniano's
    objection, dismissed the claim against Alben -- regardless of
    whether Walker's actions may have violated Justiniano's rights --
    because   Justiniano     had   not   plausibly      alleged     deliberate
    indifference or causation.
    The claims against Walker cleared the pleadings-stage
    hurdle, but stumbled when Walker moved for summary judgment on the
    ground that he acted reasonably and, regardless, was entitled to
    qualified immunity.      Indeed, in September 2018, the magistrate
    judge entered an order granting summary judgment in favor of Walker
    on the ground that his actions were not a constitutional violation
    as a matter of law.      Taking a belt-and-suspenders approach, the
    magistrate judge went on to say that even if Walker had committed
    a constitutional violation, summary judgment still was proper
    because he would be entitled to qualified immunity.             Justiniano
    appealed both dispositions of his case.
    That appeal was argued before this panel in July 2019.
    Soon thereafter, in late September, a new dimension to the case
    developed when, in connection with a separate but related matter
    pending in Massachusetts state court, Justiniano discovered new
    - 11 -
    evidence (specifically, evidence from Walker's personnel file that
    Justiniano says demonstrates Walker's propensity to be untruthful
    when disciplinary action arising from his incidents of misconduct
    is on the line -- more detail to follow) that prompted Justiniano
    to ask the magistrate judge to vacate the dismissal of the case
    against   Walker.8     The   magistrate   judge   denied   the   motion,
    explaining that Justiniano could (and should) have obtained the
    at-issue evidence in the first instance by exercising the due
    diligence required under Rule 60(b)(2) of the Federal Rules of
    Civil Procedure; but even if that was not so, the new evidence
    still would not have changed the magistrate judge's take on the
    motion for summary judgment.      Justiniano again appealed.       That
    appeal, consolidated with the original appeal, was argued to us on
    September 10, 2020.
    This brings us up to date, up to speed, and ready to
    tackle our analysis.
    8 Actually, the procedural history is a touch more labored:
    Justiniano moved pursuant to Rule 60 of the Federal Rules of Civil
    Procedure to have the magistrate judge set aside the judgment based
    on the newly discovered evidence, and the magistrate judge denied
    that motion for lack of jurisdiction. That ruling was appealed
    and ultimately vacated by an order of this court instructing that
    the Rule 60 motion be construed as a motion under Rule 62.1
    instead.   See Fed. R. Civ. P. 62.1(a) (directing that, "[i]f a
    timely motion is made for relief that the court lacks authority to
    grant because of an appeal that has been docketed and is pending,
    the court may" do one of these things: "(1) defer considering the
    motion; (2) deny the motion; or (3) state either that it would
    grant the motion if the court of appeals remands for that purpose
    or that the motion raises a substantial issue").

    DISCUSSION
    We begin making our way through the issues presented by
    reviewing the dismissal of the claim against Alben, then we'll
    pivot to our discussion of the interwoven questions centering on
    the denial of Justiniano's motion to vacate and the summary
    disposition of the claim against Walker.
    A. Alben and the Motion to Dismiss
    As always, "we give de novo review to a Rule 12(b)(6)
    failure to state a claim dismissal, using the same criteria as the
    district judge."   Zell v. Ricci, 
    957 F.3d 1
    , 7 (1st Cir. 2020)
    (alterations omitted) (citations omitted).   Recall, too, that "we
    take as true the allegations of the complaint, as well as any
    inferences we can draw from them in [Justiniano]'s favor."      
    Id.
    (citing Ocasio–Hernández v. Fortuño–Burset, 
    640 F.3d 1
    , 7 (1st
    Cir. 2011)).   As we assess the adequacy of a complaint, we are
    mindful that
    our circuit has instructed that the review should be
    handled like this:        first, "isolate and ignore
    statements in the complaint that simply offer legal
    labels and conclusions or merely rehash cause-of-action
    elements[,]" then "take the complaint's well-pled (i.e.,
    non-conclusory, non-speculative) facts as true, drawing
    all reasonable inferences in the pleader's favor, and
    see if they plausibly narrate a claim for relief."
    
    Id.
     (quoting Zenon v. Guzman, 
    924 F.3d 611
    , 615–16 (1st Cir.
    2019)); see also Schatz v. Republican State Leadership Comm., 
    669 F.3d 50
    , 55 (1st Cir. 2012) (discussing, among other cases,
    - 13 -
    Ashcroft v. Iqbal, 
    556 U.S. 662
     (2009), and Bell Atl. Corp. v.
    Twombly, 
    550 U.S. 544
     (2007)).          "Plausible, of course, means
    something   more   than   merely   possible,   and    gauging    a   pleaded
    situation's plausibility is a context-specific job that compels us
    to draw on our judicial experience and common sense."            Zell, 957
    F.3d at 7 (internal quotations omitted) (quoting Schatz, 669 F.3d
    at   55).    The   plausibility     standard   is    not   a   "probability
    requirement," but instead "asks for more than a sheer possibility
    that a defendant has acted unlawfully," Iqbal, 
    556 U.S. at
    678 --
    so if we can't infer from the well-pleaded facts "more than the
    mere possibility of misconduct," 
    id. at 679
    , then the complaint
    has not shown "that the pleader is entitled to relief," 
    id.
    (quoting Fed. R. Civ. P. 8(a)(2)).
    We start off by noting that Alben argued -- to the
    district court and before us -- a qualified immunity defense.
    However, we will not dive head first into that argument because,
    even if we were to assume that he was not entitled to such immunity,
    we would still affirm the dismissal of the count against him.           See
    Camilo-Robles v. Hoyos, 
    151 F.3d 1
    , 7 (1st Cir. 1998) (advising
    courts to separate the "qualified immunity" analysis from the
    "merits" supervisory liability analysis "whenever practicable"
    because each inquiry is "distinct").
    At the heart of the Alben motion-to-dismiss issue then
    is whether the complaint's Count 3 plausibly alleged not only that
    - 14 -
    Alben's failure to implement training to teach troopers how to
    deal     with    mentally       ill    individuals          caused      a   violation       of
    Justiniano's          constitutional           rights,    but    also   that    Alben      was
    deliberately indifferent to the risk that not providing that
    training    would       result    in       a    trooper    committing       that    kind    of
    constitutional          violation.             Justiniano,       of   course,      says    the
    complaint accomplished all of this, while Alben takes the opposite
    stance.     Before we get into those arguments, let's first canvass
    these legal principles (deliberate indifference, causation in
    failure-to-train cases) -- they're the backdrop against which
    we'll assess the complaint's sufficiency, after all.
    Alben was not on the scene, of course, so Justiniano
    relies on supervisory liability and a failure-to-train theory to
    put him on the hook.                  We've cautioned that "[t]he liability
    criteria        for    'failure       to       train'     claims      are   exceptionally
    stringent."       Hayden v. Grayson, 
    134 F.3d 449
    , 456 (1st Cir. 1998)
    (citations omitted). Generally, a supervisor cannot be held liable
    under § 1983 on a respondeat superior theory -- a "supervisor's
    liability must be premised on his [or her] own acts or omissions"
    and does not attach automatically even if a subordinate is found
    liable.     Guadalupe-Báez v. Pesquera, 
    819 F.3d 509
    , 515 (1st Cir.
    2016).      To        connect   the    liability          dots    successfully       between
    supervisor and subordinate in this context, a plaintiff must show
    "that     one     of     the     supervisor's            subordinates       abridged       the
    - 15 -
    plaintiff's      constitutional       rights"   and    that   the   supervisor's
    (in)action "was affirmative[ly] link[ed] to that behavior in the
    sense that it could be characterized as . . . gross negligence
    amounting to deliberate indifference."9 Id. at 514-15 (alterations
    omitted) (first citing then quoting Pineda v. Toomey, 
    533 F.3d 50
    ,
    54   (1st    Cir.   2008)).     And    that's   a     critical   issue   here    --
    deliberate      indifference.     Deliberate        indifference     requires     a
    plaintiff to demonstrate or allege "(1) a grave risk of harm, (2)
    the defendant's actual or constructive knowledge of that risk, and
    (3) his failure to take easily available measures to address the
    risk."      Camilo-Robles, 
    151 F.3d at 7
    ; see also Guadalupe-Báez, 819
    F.3d at 515.        Indeed, "[m]ere negligence will not suffice:                the
    supervisor's conduct must evince 'reckless or callous indifference
    9 A brief aside: as will become apparent, because we can
    resolve the appellate contentions on other requisite components of
    the global legal claims advanced by Justiniano, we really don't
    need to determine whether Walker's conduct constituted a violation
    of Justiniano's constitutional rights. This is true later, too,
    when we tackle the Walker-summary-judgment issue. We take this
    approach not only because when "it is not necessary to decide more,
    it is necessary not to decide more," Belsito Commc'ns, Inc. v.
    Decker, 
    845 F.3d 13
    , 27 (1st Cir. 2016) (quoting PDK Labs., Inc.
    v. Drug Enf't Admin., 
    362 F.3d 786
    , 799 (D.C. Cir. 2004) (Roberts,
    J., concurring in part and concurring in judgment)), but also
    because of the added wrinkle that the constitutional violation
    pled in the complaint (the shooting) differs from the
    constitutional violation argued in the Walker issue on appeal (the
    pepper-spraying).
    At any rate, in this section of analysis, as we're about to
    explain, we can do away with the arguments based on failure to
    plausibly plead deliberate indifference and causation, so we can
    assume (certainly without deciding) a constitutional violation
    transpired.

    14 F.3d 87
    , 92 (1st Cir. 1994)).
    And there's more.    "[D]eliberate indifference alone does
    not equate with supervisory liability," 
    id.
     (quoting Figueroa–
    Torres   v.    Toledo–Dávila,     
    232 F.3d 270
    ,   279    (1st    Cir.   2000)
    (alteration in original)), but rather "[c]ausation [is also] an
    essential element, and the causal link between a supervisor's
    conduct and the constitutional violation must be solid," 
    id.
    (citation omitted).      For causation in a failure-to-train claim, a
    plaintiff must allege that the "lack of training caused [the
    officer] to take actions that were objectively unreasonable and
    constituted excessive force."           Young v. City of Providence ex rel.
    Napolitano, 
    404 F.3d 4
    , 27 (1st Cir. 2005).                  And the causation
    requirement "contemplates proof that the supervisor's conduct led
    inexorably to the constitutional violation."               Guadalupe-Báez, 819
    F.3d at 515 (quoting Hegarty v. Somerset Cty., 
    53 F.3d 1367
    , 1380
    (1st Cir. 1995)).      We've observed this "is a difficult standard to
    meet," though not impossible -- for instance, a plaintiff could
    "prove causation by showing inaction in the face of a 'known
    history of widespread abuse sufficient to alert a supervisor to
    ongoing violations.'"       
    Id.
     (quoting Maldonado–Denis v. Castillo–
    Rodríguez, 
    23 F.3d 576
    , 582 (1st Cir. 1994)).                   Alternatively,
    liability      might   be   appropriate         "'in   a     narrow    range    of
    - 17 -
    circumstances' where 'a violation . . .' is 'a highly predictable
    consequence of a failure to equip law enforcement officers with
    specific tools to handle recurring situations.'"                Young, 
    404 F.3d at 28
     (quoting Bd. Of Cty. Comm'rs. of Bryan Cty., Okla. v. Brown,
    
    520 U.S. 397
    , 409 (1997)).
    So that's what needed to be alleged here -- deliberate
    indifference and causation that fit these black-letter-law bills.
    True,   "[c]ausation       and   deliberate    indifference         are    separate
    requirements . . . [, but] they are often intertwined in these
    cases."    Id. at 26.      So it is here -- both determinations turn on
    whether Alben was aware of a risk that his subordinates (Walker,
    in   particular)       might     violate      mentally       ill        individuals'
    constitutional rights.
    Justiniano says the complaint does plenty to state this
    claim plausibly, and thus it should have survived the Rule 12(b)(6)
    motion.    Count 3 alleges that Alben, as Walker's supervisor and a
    policymaker, failed to provide Walker with the proper training and
    resources    that    would   have   helped    to    prevent     a   violation      of
    Justiniano's constitutional rights (again, the complaint leans on
    the lethal force as the violation).             Justiniano argues that the
    complaint adequately alleges that Alben was aware of and ignored
    national    trends    indicating    a   problematic      rise      in   bad-outcome
    encounters       between   police   and    mentally    ill      individuals       but
    provided    no    specialized    training,    and    that    failure       to   train
    - 18 -
    constituted deliberate indifference to an obvious risk.                  And,
    according to Justiniano, the complaint plausibly lays out the
    requisite causal nexus by alleging that the sought-after de-
    escalation training would have prevented this tragedy, meaning
    Walker's lack of training by Alben was the cause of the violation
    of Justiniano's rights.
    Alben disagrees, asserting that the complaint falls
    short of alleging facts sufficient to establish that he acted with
    deliberate indifference to Justiniano's constitutional rights (or,
    put   differently,   that   Alben    had     notice   of   conduct   violating
    constitutional rights but failed to take steps to address it),
    and, on top of that, the complaint does not adequately allege that
    proper training would have prevented that violation (i.e., no
    causation).
    With the benefit of every possible doubt -- accepting
    all of the complaint's factual allegations as true, Zell, 957 F.3d
    at 7, assuming that a constitutional violation occurred, drawing
    all reasonable inferences in Justiniano's favor, and "isolat[ing]
    and ignor[ing]" mere legal conclusions -- this claim's "non-
    conclusory, non-speculative" factual allegations do not "plausibly
    narrate a claim for relief," id. (quoting Zenon, 924 F.3d at 615–
    16), so Justiniano's Count 3 as pled does not pass muster.
    In broad strokes, as to the alleged facts that arguably
    could support the supervisory liability theory, this is what the
    - 19 -
    complaint does accomplish:     that Alben, as supervisor, did not
    have specific policies in place "for dealing with mental health
    crises without using lethal force" or "for troopers dealing with
    mental health crises on techniques to de-escalate"; that Alben was
    aware of national trends showing an increase in the number of
    mental health crises and a corresponding increase in the number of
    death-resulting encounters with police which have prompted some
    law enforcement entities to institute training regarding these
    issues, but Alben took no "affirmative action," which may have
    contributed to Justiniano's death.        It then asserts that Alben's
    failure to act in the face of these national trends "demonstrates
    a deliberate indifference" to Justiniano's civil rights, and,
    "[a]s a direct result of" Alben's conduct, Justiniano died.
    It is not difficult to see what Justiniano was trying to
    do here. But these alleged facts don't support the essential legal
    elements   of   "reckless     or   callous     indifference    to    the
    constitutional rights of others," Guadalupe-Báez, 819 F.3d at 515
    (quoting Febus-Rodríguez, 
    14 F.3d at 92
    ), and the "solid" "causal
    link between [Alben]'s conduct and the constitutional violation,"
    
    id.
     (citation omitted), that Justiniano needed to state in order
    to be entitled to relief as a matter of law.
    Starting   with   deliberate     indifference,   it's    clear
    Justiniano's aim was to highlight the absence of training when it
    comes to police encounters with the mentally ill -- Alben himself
    - 20 -
    acknowledged that shortcoming in the system, as the complaint
    alleges -- and to try to link that to wrongdoing by Alben.           But
    there are too many pieces missing, even with the benefit of some
    inferential leaps, for us to conclude deliberate indifference has
    been plausibly pled.
    For instance, there are no non-speculative facts in the
    complaint that allege a specific "grave risk of harm" in failing
    to train or that there were "easily available measures to address
    the risk" that Alben could have taken but didn't.        Camilo-Robles,
    
    151 F.3d at 7
    ; see also Guadalupe-Báez, 819 F.3d at 515.       There is
    no allegation that the referenced mental health training adopted
    by some other jurisdictions would have been easy to implement in
    Massachusetts, nor that the trainings actually have been effective
    in reducing the frequency of constitutional violations of the
    mentally ill.     See, e.g., Rodriques v. Furtado, 
    950 F.2d 805
    , 813
    (1st Cir. 1991) (explaining that arguable weaknesses with respect
    to police training or supervision don't necessarily equate to
    deliberate-indifference failure to train).     And even if there were
    such allegations, it still would not be enough to suggest plausibly
    that Alben knew or should have known his troopers might violate
    the rights of a mentally ill individual, particularly when there
    is   no   known   history   of   such   constitutional   trampling    by
    Massachusetts troopers alleged.     The complaint does not plead that
    Walker or the Massachusetts State Police more generally had a
    - 21 -
    history of using excessive and constitutionally violative force
    against individuals who were mentally ill such that Alben should
    have been on notice of that conduct, nor is there any suggestion
    that the Massachusetts State Police are otherwise specifically at
    risk    of   violating   a   mentally   ill   individual's   constitutional
    rights.      See Guadalupe-Báez, 819 F.3d at 516.       Clearly, then, he
    could not have ignored -- with deliberate indifference or otherwise
    -- a non-existent history of these issues.10
    Another angle would be to consider whether the complaint
    plausibly alleged a national trend of constitutional violations so
    prominent that Alben should have been (or was) on notice of a high
    10   On the deliberate indifference/notice front, by
    comparison, consider the facts and outcome in Guadalupe-Báez: a
    man was shot, and although he was not able to identify his shooter,
    he had reason to believe it was a local police officer. 819 F.3d
    at 513.    The supervisory failure alleged there centered on a
    lackluster police investigation into the matter. Id. at 516. In
    concluding the plaintiff barely met the pleading standard, a panel
    of this court put emphasis on the particular police force's
    "tarnished history" of civil rights violations and a Department of
    Justice report calling out that specific police force's issues.
    Id. at 512.    And then there's Young, in which a friendly-fire
    incident saw on-duty uniformed officers shoot an off-duty officer
    who was responding to the same incident. 
    404 F.3d at 9
    . The Young
    court found supervisory liability despite the absence of a history
    of past violations because the police department's policy required
    off-duty officers to remain armed and respond to situations they
    encountered. 
    Id.
     Because officials made statements suggesting
    they were aware of a high risk of a friendly-fire incident in these
    circumstances, and because the police force's training did not
    necessarily prepare on-duty officers for the inherently dangerous
    possibility of an armed and responding off-duty officer, the court
    explained that a jury could have found the officers to have been
    deliberately indifferent to a risk of this shooting. 
    Id.

    19, 28.
    - 22 -
    risk that, without this training, there was a grave risk that his
    troopers would violate a mentally ill person's constitutional
    rights, and he nonetheless ignored it.            See Young, 
    404 F.3d at 28
    .
    But the complaint does not allege such a widespread, prominent
    trend of constitutional violations:            in fact, the complaint does
    not   actually   allege    that   the    "trend"     involves       constitutional
    violations at all, but instead states that there are more and more
    "tragic encounters with police where unarmed mentally ill citizens
    end up dead." While we do not purport to foreclose the possibility
    that such a national trend might be enough to provide this notice,
    the trend as alleged here simply does not rise to that level.
    And the requisite causal link has not been plausibly
    alleged either, i.e., that Alben's failure to train his troopers
    "caused     [Walker]      to   take     actions      that        were    objectively
    unreasonable and constituted excessive force."                   Young, 
    404 F.3d at 27
    .   Justiniano pleads that "[a]s a direct result of the conduct
    of Defendant Alben, Wilfredo Justiniano lost his life," but none
    of the pled conduct supports that legal conclusion.                     And while the
    complaint    alleges    that   Walker     acted    improperly           in   light   of
    Justiniano's     mental    condition,     there      is     no    allegation     that
    Walker's decision to shoot Justiniano was related to any mental
    illness that Justiniano suffered.          Yes, the complaint alleges that
    Walker    confronted,     fired   his    gun   at,    and        ultimately    killed
    Justiniano, who was unarmed and experiencing a mental health
    - 23 -
    crisis, but, even if all of that was proven, there still could be
    no non-speculative inference from those facts that, had Alben
    provided the training, the shooting would not have happened.
    Recall, too, that we've said a plaintiff could "prove
    causation [in this context] by showing inaction in the face of a
    'known history of widespread abuse sufficient to alert a supervisor
    to ongoing violations,'" Guadalupe-Báez, 819 F.3d at 515 (quoting
    Maldonado–Denis, 
    23 F.3d at 582
    ), and it could be alleged by
    pleading   that    certain   conduct     "is   'a   highly   predictable
    consequence of a failure to equip law enforcement officers with
    specific tools to handle recurring situations,'" Young, 
    404 F.3d at 28
     (quoting Brown, 
    520 U.S. at 409
    ).        This is a non-exhaustive
    set of examples, certainly, but nothing even approaching these
    scenarios happened here (as we touched on in part in our deliberate
    indifference discussion).      Instead, the complaint conclusorily
    alleges that Alben's refusal to change the relevant policies led
    to the "inevitable outcome" of Justiniano's death, but does nothing
    to allege non-speculative facts that would allow an inference that
    training actually would have altered that outcome.
    All told, we needed "more than a sheer possibility that
    [Alben] . . . acted unlawfully[,]" but we didn't get it.         Iqbal,
    
    556 U.S. at 678
    .     There's not enough factually alleged here to
    support a conclusion that Alben acted with deliberate indifference
    when he neglected to train Walker (and other troopers) on how to
    - 24 -
    interact   with    the   mentally   ill;   and,   regardless    of    that
    shortcoming, there's still a dearth of factual allegations to
    bolster the conclusion that his failure to do so caused Walker to
    violate Justiniano's rights.        Therefore, we affirm the district
    court's dismissal of the claim against Alben.
    B. Walker and the Motion for Summary Judgment
    We thus move on, turning our gaze to the summary judgment
    granted to Walker and ensuing new-evidence litigation.         Here's how
    that will go:     we'll first explain everything that happened below
    -- the summary-judgment grant as to Count 1 followed by the denial
    of the motion to vacate -- then lay out the rules of engagement
    for qualified-immunity arguments before turning to the parties'
    appellate contentions, all of which we'll assess under de novo
    review because, as we'll explain, even if we look at all the
    evidence (both old and new), a de novo review of the entire matter
    still leads to an affirmance based on qualified immunity.            Let's
    begin.
    i.   Proceedings Below
    Starting with Walker's motion for summary judgment,
    here's the gist of how this issue went below.
    Walker moved for summary judgment on the ground that he
    did not violate Justiniano's rights and, in any event, was entitled
    to qualified immunity.        In opposition, Justiniano argued there
    were genuine issues of material fact (focusing in particular on
    - 25 -
    whether Justiniano was wielding a weapon (the pen); what, exactly,
    was said between Walker and Justiniano; and, overall, whether
    Walker could have reasonably felt threatened) and that qualified
    immunity should not attach because Walker's conduct constituted an
    unconstitutional and unreasonable use of excessive force that
    violated a protected right that was clearly established at the
    time, especially given that Justiniano "posed no imminent threat."
    In fielding that motion, the magistrate judge considered the
    evidence, including evidence from civilian witnesses and evidence
    from Walker that Justiniano was brandishing a ballpoint pen as a
    weapon and made threatening statements to Walker.11                       Justiniano v.
    Walker, 
    2018 WL 4696741
    , at *2-3 (D. Mass. Sept. 30, 2018).                              In
    finding that, based on the entire record, Walker acted reasonably
    under        the    circumstances,    the    magistrate      judge       concluded   that
    Walker therefore did not use excessive force.                       Id. at *5.       And,
    moreover,          even    if   Walker's    conduct   had   constituted       excessive
    force,        the    magistrate     judge    indicated      that    Walker       would   be
    protected by the cover of qualified immunity because "a reasonable
    officer would not have clearly understood Trooper Walker's conduct
    to be unreasonable" since Justiniano "posed an imminent threat" -
    -   indeed,         that    reasonable      officer   "would       not    have    readily
    11
    Recall from our earlier factual recitation that no witness
    could hear anything being said by either Justiniano or Walker, nor
    could any witness confirm that Justiniano was holding a pen in
    this manner (though a pen was found on the road after the fact).
    - 26 -
    understood    Trooper     Walker's     actions    to   violate    Justiniano's
    rights."   Id. at *6.     The court accordingly granted the motion for
    summary judgment.       Id.
    As discussed, that ruling was appealed, and while the
    appeal was pending, the new-evidence issue materialized.                 Here's
    what the new evidence was and how it came to light. In the parallel
    litigation     taking    place   in     the    Massachusetts     state   court,
    Justiniano's motion to compel production of certain documents
    (which had been requested but not been produced in the federal
    case) was granted, providing access to some of Walker's personnel
    file, including disciplinary reports regarding Walker, training
    reports, and some emails.        Justiniano v. Walker, 
    2019 WL 7169785
    ,
    at *1-2, *4 (D. Mass. Dec. 24, 2019).                  Justiniano says this
    evidence matters because it demonstrates Walker's history of lying
    while under investigation in two prior misconduct matters, that he
    (a) violated department policy when he failed to create a use of
    force report within the required 24-hour period after Justiniano's
    shooting, and (b) lied under oath in his deposition in this matter
    when he represented that he had written the report when, according
    to the State Police producing the compelled documents, no such
    report could be found.12         In view of this new evidence showing
    12 Obviously, to the extent this was indeed a lie under oath
    as Justiniano asserts, we do not condone perjury. But, as we'll
    explain, we do not need to get into whether that is what happened.
    - 27 -
    (according to Justiniano) that Walker has a spotty history when it
    comes to truth-telling, Justiniano argued the summary-judgment
    grant should be vacated because Walker's uncorroborated statements
    regarding the incident with Justiniano are no longer credible,
    meaning there are genuine issues of material fact as to whether
    the incident transpired as Walker indicated and thus, whether he
    acted reasonably when he pepper-sprayed Justiniano.
    Back       before   the    lower      court   after    our    remand,       the
    magistrate judge first concluded that, in view of our due-diligence
    Rule 60 caselaw, Justiniano should have done more to obtain this
    evidence    in    the     instant      litigation,        i.e.,    pursue     an    order
    compelling production. Id. at *5-6. Then, in an exercise of even-
    if thoroughness, the magistrate judge went on to assume arguendo
    that, had the due-diligence hurdle been surmounted, the relief
    Justiniano sought (vacating the summary-judgment grant) still
    would not be granted because the new evidence wouldn't change the
    outcome:    even removing Walker's uncorroborated statements from
    consideration,         Walker    was       nonetheless    entitled       to   qualified
    immunity.        Id.    at    *6-7.        The   magistrate    judge     assessed       the
    qualified-immunity           issue    --    minus   Walker's      statements       --   and
    concluded that, on this record, Walker had not acted unreasonably:
    an objectively reasonable officer in Trooper Walker's
    position would not have understood that emitting a burst
    of pepper spray to retard Justiniano's movements
    violated his rights. On the contrary, the undisputed
    facts demonstrate that Justiniano appeared agitated and
    - 28 -
    distraught when Trooper Walker arrived, Trooper Walker
    tried to calm him down by holding up his hands,
    Justiniano did not comply, and Trooper Walker used the
    pepper spray only after he was forced to back up into
    [the highway].
    Id. at *7.13
    ii.   Ground Rules:    Qualified-Immunity Law
    We need not grapple with the front-end issue of whether
    the new evidence should have been discovered in this action with
    the exercise of due diligence because, even if it had been, its
    existence in this record does not alter the outcome:           Walker is
    still protected by qualified immunity.        We thus proceed under the
    assumption that the new evidence can be considered, meaning we
    take Walker's uncorroborated statements off the evidentiary table
    as we analyze the qualified-immunity question here.
    We begin with a primer on the standard of review, the
    qualified-immunity test, and the guidance our caselaw provides.
    We review a grant of summary judgment de novo, drawing
    all reasonable inferences in the light most favorable to the
    nonmoving party.       Mitchell v. Miller, 
    790 F.3d 73
    , 76 (1st Cir.
    2015) (citing Alicea v. Machete Music, 
    744 F.3d 773
    , 778 (1st Cir.
    2014)).   Our caselaw and Rule 56 of the Federal Rules of Civil
    Procedure teach us to affirm the grant of summary judgment only if
    13 Recall that, as we mentioned a few pages back, Justiniano's
    appellate focus is on the pepper spraying only, not the lethal
    force.
    - 29 -
    "there is no genuine dispute as to any material fact" and, as a
    result, the moving party is "entitled to judgment as a matter of
    law."   Id. at 76-77 (quoting Bos. Prop. Exch. Transfer Co. v.
    Iantosca, 
    720 F.3d 1
    , 10 (1st Cir. 2013)); see also Fed. R. Civ.
    P. 56(a). Importantly, to avoid "the swing of the summary judgment
    scythe," the nonmoving party must adduce specific facts showing
    that a trier of fact could reasonably find in his favor, Mulvihill
    v. Top-Flite Golf Co., 
    335 F.3d 15
    , 19 (1st Cir. 2003), the
    nonmovant    cannot   rely   on   "conclusory   allegations,   improbable
    inferences, and unsupported speculation," Medina-Muñoz v. R.J.
    Reynolds Tobacco Co., 
    896 F.2d 5
    , 8 (1st Cir. 1990).
    This lens of review in place, we turn to qualified
    immunity -- much referenced thus far, but not yet subject to a
    deep-dive, so in we go.       "Qualified immunity protects an officer
    from suit when a reasonable decision in the line of duty ends up
    being a bad guess -- in other words, it shields from liability
    'all but the plainly incompetent or those who knowingly violate
    the law.'"    Decker, 845 F.3d at 22 (quoting Taylor v. Barkes, 
    575 U.S. 822
    , 822 (2015)). "'[R]easonable mistakes,' the Supreme Court
    tells us, 'can be made as to the legal constraints' on officers,
    and when that happens, the officer is qualifiedly immune from
    damages."    
    Id.
     (alteration in original) (quoting Saucier v. Katz,
    
    533 U.S. 194
    , 205 (2001), overruled on other grounds by Pearson v.
    Callahan, 
    555 U.S. 223
     (2009)). Here, to quash Walker's qualified-
    - 30 -
    immunity defense, Justiniano needed to "show (1) that [Walker]
    infracted [Justiniano's] federal rights and (2) that these rights
    were so clearly established that a reasonable officer should have
    known how they applied to the situation at hand."                 
    Id.
     at 23
    (citing City & Cnty. of S.F. v. Sheehan, 
    575 U.S. 600
     (2015);
    Pearson, 
    555 U.S. at 232
    ; Cortés-Reyes v. Salas-Quintana, 
    608 F.3d 41
    , 51-52 (1st Cir. 2010)). In fact, we routinely break the second
    prong down even more explicitly as follows:           "'whether the right
    was clearly established at the time of the alleged violation,' and
    'whether   a   reasonable     officer,      similarly      situated,     would
    understand that the challenged conduct violated that established
    right.'"    Parker v. Gerrish, 
    547 F.3d 1
    , 12 (1st Cir. 2008)
    (quoting   Philip   v.   Cronin,   
    537 F.3d 26
    ,   34   (1st   Cir.   2008)
    (reasoning that, even if a constitutional right has been clearly
    established, a defendant may nonetheless be protected by qualified
    immunity if a reasonable official in the defendant's position could
    have believed (even wrongly) that the at-issue conduct was not
    violative of a constitutional right)); see also Savard v. Rhode
    Island, 
    338 F.3d 23
    , 27 (1st Cir. 2003) (en banc) (referring to
    the qualified-immunity test as a "three-part algorithm").                 And
    breaking the clearly-established element down in this way makes
    good sense: "a defendant cannot be said to have violated a clearly
    established right unless the right's contours were sufficiently
    definite that any reasonable official in the defendant's shoes
    - 31 -
    would have understood that he was violating it," Plumhoff v.
    Rickard, 
    572 U.S. 765
    , 778–79 (2014), i.e., "'existing precedent
    must     have     placed      the    statutory      or    constitutional       question'
    confronted by the official 'beyond debate,'" id. at 779 (quoting
    Ashcroft v. al–Kidd, 
    563 U.S. 731
    , 741 (2011)).
    We can tackle these components of the qualified-immunity
    test in any order we like.             Pearson, 
    555 U.S. at 236
    .           Here, we'll
    assume without deciding the first pieces have been shown --
    Walker's use of the pepper spray violated Justiniano's right to be
    free from that force, and that right was clearly established and
    on the books in June 2013 -- and resolve the matter on the question
    of     whether     a   reasonable,         similarly       situated     officer    would
    understand         that       Walker's          conduct     violated      Justiniano's
    constitutional right.14             See Parker, 
    547 F.3d at 12-13
    .             As we do
    so, we keep in mind that, because "[c]ourts penalize officers for
    violating bright lines, not for making bad guesses in gray areas,"
    Rivera–Corraliza,            794    F.3d   at    215     (internal    quotation    marks
    omitted),        if    the     pertinent        "legal     principles    are      clearly
    established only at a level of generality so high that officials
    cannot      fairly     anticipate      the      legal     consequences    of    specific
    14
    Because we will dispose of the matter in this way, we need
    not get into the constitutionality of Walker's conduct.        See
    Decker, 845 F.3d at 23 n.8 (taking a similar approach in a
    qualified immunity matter); Barton v. Clancy, 
    632 F.3d 9
    , 12, 30
    n.20 (1st Cir. 2011) (same). Remember, this is what we did in the
    Alben analysis, as well.
    - 32 -
    actions, then the requisite notice is lacking," Savard, 338 F.3d
    at 28.
    We are also mindful that deciding qualified immunity at
    the summary-judgment stage can be tricky.           See Morelli v. Webster,
    
    552 F.3d 12
    , 18-19 (1st Cir. 2009) (discussing the "inherent
    tension" between qualified immunity and summary judgment).                Yes,
    "qualified immunity is 'an immunity from suit rather than a mere
    defense to liability,'" meaning "'it is effectively lost if a case
    is erroneously permitted to go to trial,'" Pearson, 
    555 U.S. at 231
     (quoting Mitchell v. Forsyth, 
    472 U.S. 511
    , 526 (1985)), so
    qualified immunity's applicability "should be resolved at the
    earliest possible stage of litigation," Rocket Learning, Inc. v.
    Rivera-Sánchez, 
    715 F.3d 1
    , 8 (1st Cir. 2013) (citing Maldonado v.
    Fontanes, 
    568 F.3d 263
    , 268 (1st Cir. 2009)).                   But, as we've
    observed, "[t]he doctrinal intersection of qualified immunity
    principles and summary judgment principles is not well mapped,"
    and "[p]lotting that intersection can present thorny analytic
    problems -- problems that are magnified because of the desire to
    resolve claims of qualified immunity at the earliest practicable
    stage of litigation."        Morelli, 
    552 F.3d at
    18 (citing Cox v.
    Hainey,   
    391 F.3d 25
    ,   29   (1st   Cir.    2004)).    Furthermore,     in
    qualified-immunity     summary-judgment         cases,   it's   a   tug-of-war,
    really, between who gets the benefit of the doubt:                      summary
    judgment "requires absolute deference to the nonmovant's factual
    - 33 -
    assertions," while qualified immunity "demands deference to the
    reasonable, if mistaken, actions of the movant."        Id. at 18-19.
    We aim to resolve all of this tension by framing the
    factual events according to summary judgment's traditional leeway
    to the nonmoving party's version of events, and then asking
    whether, given that story, "a reasonable officer should have known
    that his actions were unlawful."     Id. at 19.
    iii.   Walker is Qualifiedly Immune
    Justiniano contends that the record contains enough
    conflicting testimony about material facts to raise a genuine
    dispute over whether Walker can be shielded by qualified immunity,
    i.e., whether Walker's use of pepper spray was an inappropriate
    and excessive use of force in violation of Justiniano's clearly
    established right to be free from that use of force.           And she
    argues that the new evidence in particular "leaves a universe of
    facts that support [her] claims": no one but Walker saw Justiniano
    yelling in the road, heard any verbal threat by Justiniano, saw
    anything in Justiniano's hands, or heard Walker give Justiniano
    warnings about his intent to deploy force.     In Justiniano's view,
    since there's no witness who testifies that Justiniano was doing
    anything other than simply approaching Walker when the pepper spray
    was deployed, it is valid to infer the nature of his movement was
    nonthreatening, and thus it was not reasonable for Walker to use
    the spray.
    - 34 -
    Walker, in turn, argues that none of the facts to which
    Justiniano points lead to the conclusion that he is not shielded
    by qualified immunity, and this is so even if all of Walker's
    uncorroborated testimony is removed from consideration.
    So now, as we leapfrog the initial elements of the
    qualified-immunity analysis (recall that we're assuming arguendo
    that the use of the pepper spray was unreasonable and Justiniano
    had a clearly established right to be free from that use of force),
    we confront the question of whether a reasonable officer in
    Walker's shoes would have understood Walker's conduct to violate
    Justiniano's constitutional right.           See, e.g., Parker, 
    547 F.3d at 12
    .
    Even viewing the facts in the light most favorable to
    Justiniano,     removing     from    consideration      any   of     Walker's
    uncorroborated testimony, and drawing all reasonable inferences in
    Justiniano's favor, the record here does not support a finding
    that a reasonable officer would have clearly understood Walker's
    conduct to be an unreasonable violation of Justiniano's rights.
    Our careful review of the record here leaves us with
    these undisputed facts to sketch the contours of what happened.
    Kyriakides observed Justiniano driving erratically, and when they
    both   pulled   over,   he    was    confused,     distraught,     and   spoke
    unintelligibly.     She was scared for Justiniano's wellbeing, as
    well as her own and that of passersby.          After Walker hit the scene,
    - 35 -
    all   three    civilian     witnesses    (Kyriakides,     Silva-Winbush,    and
    MacKeen) observed Walker at various points trying to calm down
    and/or stop Justiniano from approaching him by using hand gestures.
    They also described Justiniano as appearing distraught, even mad;
    none observed Justiniano heeding Walker's hand gestures to calm
    down or stop his approach.              Silva-Winbush, who witnessed each
    instance of pepper-spraying, indicated that the first use of the
    spray (the complained-of rights-violation here) came only after
    Walker had "jumped" into the highway as he continued to retreat
    from Justiniano.      And each of these witnesses described various
    instances of Justiniano lunging or at least engaging in forward
    motion towards Walker.
    From an objective standpoint, a reasonable officer could
    have believed Justiniano posed a threat, and thus that same
    reasonable officer, in Walker's position, would not have believed
    that the initial use of pepper spray (a generally non-lethal
    deployment)      against     Justiniano     constituted     a   violation    of
    Justiniano's      rights.      A   contrary    finding,    even   a   contrary
    inference, is simply not supportable on the evidence here.
    True,   witnesses      describe     Justiniano's        movements
    differently, and movement alone wouldn't necessarily justify the
    use of pepper spray.           And yes, the key here is Justiniano's
    movements (or lack thereof, if that was the case) in the moments
    before and as the pepper spray was used -- Justiniano being
    - 36 -
    stationary, or approaching Walker in a decidedly nonaggressive
    fashion, for example, because that's what a jury could rely on to
    make inferences that Justiniano's behavior did not warrant the use
    of force he received because Walker couldn't have reasonably
    thought Justiniano posed a threat.               But there is no witness
    testimony that Justiniano was stationary in the moment before the
    pepper   spray   was    used;   rather,   all    the    evidence     points   to
    Justiniano   steadily     moving   towards   Walker      in   one   fashion   or
    another.   Yes, MacKeen indicated both men were stationary when she
    first saw them, but for one thing, it's not entirely clear when
    exactly she observed this (as best we can tell, it's probably after
    the pepper-spraying went down, and just before the shooting --
    either way, she doesn't say when Justiniano was stationary in
    relation to when the pepper spray was used), and for another, she
    said Justiniano did then approach Walker.               And there's nothing
    that would support a reasonable inference that the nature of any
    of   Justiniano's      movements   forward      was    anything     other   than
    aggressive if not downright threatening (even if Justiniano's
    behavior is sadly explained by his mental state).                   See, e.g.,
    Suarez v. Pueblo Int'l, Inc., 
    229 F.3d 49
    , 53 (1st Cir. 2000) ("[A
    plaintiff] cannot rely on an absence of competent evidence, but
    must affirmatively point to specific facts that demonstrate the
    existence of an authentic dispute." (quoting McCarthy v. Nw.
    Airlines, Inc., 
    56 F.3d 313
    , 315 (1st Cir. 1995))).                  Quite the
    - 37 -
    opposite:     in    the   face   of   the   evidence   we   do   have   about
    Justiniano's demeanor, reaching such a conclusion would require
    impermissible guesswork and speculation.           Justiniano needed to
    point to specific facts that would allow a jury to find in her
    favor on this point, Mulvihill, 
    335 F.3d at 19
    , but we find
    ourselves    left    only   with      arguments   requiring      "improbable
    inferences[] and unsupported speculation" to reach the outcome she
    seeks, Medina-Muñoz, 
    896 F.2d at 8
    .           Even framing the facts as
    favorably as we can according to Justiniano's version of events
    (no pen-as-weapon in the narrative, no threats issued to Walker by
    Justiniano), we cannot conclude on this record that a reasonable
    officer in Walker's position would have known his conduct (using
    the pepper spray) was unlawful under these circumstances.                See,
    e.g., Morelli, 
    552 F.3d at 19
    .        Accordingly, the magistrate judge
    was correct that Walker is entitled to qualified immunity.15
    Therefore, we affirm the grant of summary judgment, and,
    15 Justiniano directs us to Gray v. Cummings, 
    917 F.3d 1
     (1st
    Cir. 2019), another qualified-immunity case involving an encounter
    between a mentally ill individual and a law enforcement officer.
    The goal, it seems, was to argue that a person's mental illness
    must be considered when an officer decides to employ force against
    that individual. But the Gray court's conclusion was that a
    reasonable officer wouldn't have believed using a taser on the
    lowest stun setting to halt a nonviolent, mentally ill individual
    resisting arrest was a violation.     Id. at 12.    This does not
    undermine any of our analysis: a reasonable officer in Walker's
    shoes could have believed that the first use of pepper spray on
    Justiniano (who was behaving erratically, moving forward toward
    Walker and oncoming traffic on a highway and not known to Walker
    to be mentally ill) wasn't a constitutional violation.
    - 38 -
    for the same reasons, we affirm the denial of the Rule 60 motion
    to vacate.16
    WRAPPING UP
    Before we go, we note that Justiniano also briefed an
    16  A housekeeping matter. Justiniano urges us to conclude
    that the magistrate judge abused his discretion when he refused to
    vacate his earlier summary-judgment grant. In so doing, Justiniano
    raises arguments under both sections (b)(2) and (b)(3) of Rule 60.
    Rule 60(b)(2), dealt with by the lower court because it was argued
    there, provides that a party can be relieved from a judgment like
    the one entered here if there is "newly discovered evidence that,
    with reasonable diligence, could not have been discovered in time
    to move for a new trial under Rule 59(b)." Rule 60(b)(3), raised
    for the first time on appeal, instructs that relief can be granted
    where there's "fraud (whether previously called intrinsic or
    extrinsic), misrepresentation, or misconduct by an opposing
    party." According to Justiniano, the magistrate judge abused his
    discretion in his handling of the Rule 60 motion for reasons
    falling under each of these two sections of that rule. But here's
    the thing:   even taking as not waived the (b)(3) argument that
    fraud and misconduct by the Massachusetts State Police is what
    kept the evidence from being discovered in this action, these
    components of Rule 60(b) assume that the at-issue evidence was
    never discovered, accessed, or considered in ruling on the original
    dispositive motion the Rule 60(b) motion seeks to vacate -- and
    that's precisely why the rule exists, to remedy just such a plight.
    Here, we've already said (ad nauseum) that we assume favorably to
    Justiniano that the "newly discovered evidence" could be
    considered, and doing that had the effect of negating all of
    Walker's uncorroborated testimony. That's exactly the point that
    Justiniano wanted to make in arguing that the summary-judgment
    grant should not stand. But the thrust of Rule 60(b) as applied
    here is that the excluded or inaccessible evidence would need to
    change the outcome on the dispositive motion. We let it in, and
    it didn't alter the outcome of our qualified-immunity analysis.
    So we do not tarry any further on this because, with the outcome
    determined to be the same with or without the evidence, the
    magistrate judge did not abuse his discretion in fielding the Rule
    60 motion as he did.

    argument urging us to abandon the application of qualified immunity
    in cases resulting in death.   As we acknowledged at the outset of
    today's decision, we do not disagree that the issue of qualified
    immunity's role in our jurisprudence is topical, to say the least.
    But we are constrained by the precedent that led to today's
    outcome, and until that precedent changes, we are dutybound to
    apply it.
    For the reasons explained in detail above, we affirm
    across the board the lower court's disposition of this case.   Each
    side to bear its own costs.
