    Katherine Wray (Margaret Strickland, McGraw & Strickland, Las Cruces, New
    Mexico, with her on the briefs) Wray & Girard, PC, Albuquerque, New Mexico,
    for Appellant.
    Damian L. Martinez (Haley R. Grant with him on the brief), Holt Mynatt Martinez
    P.C., Las Cruces, New Mexico, for Appellees.
    Before TYMKOVICH, Chief Judge, BALDOCK, and CARSON, Circuit Judges.
    PER CURIAM
    This appeal arises from allegations of deliberate indifference to violence
    among pretrial detainees at a juvenile detention facility in Doña Ana County, New
    Mexico. After A.L. was booked into the Doña Ana County Detention Center,
    three other detainees threatened him with physical harm. Corrections officers
    responded by imposing a highly-restrictive lockdown regime on all three
    aggressors. Despite these countermeasures, one of the aggressors—while
    temporarily permitted outside of his cell—accessed the touchscreen control panel
    that regulated access to cells within the juvenile pod. While corrections officers
    were distracted, he opened several cells simultaneously. The other two aggressors
    took this opportunity to physically assault A.L.
    Kathy Contreras, A.L.’s mother, subsequently brought this lawsuit against
    the three corrections officers present during the attack, as well as the Doña Ana
    County Detention Center. She alleges the defendants violated A.L.’s Fourteenth
    Amendment right to substantive due process through deliberate indifference to the
    violence threatened by other detainees. The district court granted the defendants’
    motion for summary judgment on the basis of qualified immunity. On appeal, a
    majority of the court concludes the district court did not err. No legal authorities
    clearly establish a constitutional violation under these circumstances.
    -2-
    We accordingly affirm the judgment of the district court. 1 Chief Judge
    Tymkovich concurs, concluding that no constitutional violation occurred. Judge
    Carson concurs, concluding that he would dispose of this case without
    determining whether a constitutional violation occurred. Judge Baldock concurs
    in part and dissents in part. He concurs in the affirmance of summary judgment
    in favor of Defendants Jaime Casado and Shaylene Platero, but he dissents as to
    Defendants Paco Luna and Doña Ana County, concluding (1) Sergeant Luna
    violated A.L.’s clearly established constitutional right to protection from
    violence, and (2) Doña Ana County should also be liable for that violation.
    1
    A majority of this court likewise affirms the district court’s decision to
    grant summary judgment to the municipality. Chief Judge Tymkovich concurs on
    the basis that no constitutional violation occurred, which forecloses municipal
    liability entirely. Judge Carson concurs on the basis that—although qualified
    immunity only shields individuals—municipal liability for claims of deliberate
    indifference must follow only from clearly established constitutional violations.

    18-2176, Contreras v. Doña Ana Board of County Commissioners
    TYMKOVICH, Chief Judge, concurring.
    In my view, Ms. Contreras has failed not only to demonstrate the violation
    of a clearly established constitutional right, but also the violation of a
    constitutional right at all.
    I. Background
    On the evening of May 3, 2016, A.L. was booked into the Doña Ana
    County Detention Center (DACDC) for violating terms associated with his
    probation. As A.L. was led to his cell, three other detainees—A.H., J.S., and
    J.V.—spontaneously began banging on their cell doors and yelling to A.L. that
    they “were gonna f**k him up.”
    In response, corrections officers placed all three aggressors on pre-
    disciplinary lockdown (“pre-disc”), which imposed a number of restrictions.
    While subject to pre-disc, A.H., J.S., and J.V. could only leave their cells for one
    of several enumerated purposes, and never at the same time. This regime also
    proscribed any contact with A.L. And it likewise sought to restrict
    communication among the three aggressors.
    The next morning, Officer Casado, Cadet Platero, and Sergeant Luna were
    in the common area on the first floor of the juvenile pod. While A.L., J.S., and
    J.V. remained locked in separate cells on the second floor, A.H. obtained
    permission to leave his cell for the permissible purpose of a shower. The shower
    room sat on the first floor, just adjacent to the common area.
    Video indicates all three corrections officers watched television in the
    common area as A.H. finished his shower. Consistent with the restrictions
    imposed by A.H.’s pre-disc, no other detainee appeared outside of the locked
    cells. Upon exiting the shower room, A.H. entered the common area, which
    houses both the commissary kiosk and the touchscreen control panel. The record
    discloses that Officer Casado had left the control panel unlocked.
    A.H. obtained permission from Sergeant Luna to use the commissary kiosk.
    But as he stands at the kiosk, the video suggests A.H. glances over his shoulder to
    check whether the corrections officers were paying attention. He then walks off-
    screen. Moments later, one of the corrections officers—evidently recognizing
    something amiss—stands suddenly as A.H. reappears onscreen. Around this same
    time, J.S. and J.V. flee their newly-unlocked cells.
    They enter A.L.’s cell, closing the door behind them. J.S. and J.V. then
    begin assaulting A.L. As they do so, A.H. runs upstairs and locks himself inside
    his own cell, before Officer Casado can catch him. From downstairs, Cadet
    Platero re-opens A.L.’s cell. Sergeant Luna eventually subdues A.L.’s attackers
    with pepper spray. All of this transpires within twenty seconds.

    II. Analysis
    Ms. Contreras contends the district court erred in concluding the
    corrections officers’ behavior did not violate a clearly-established constitutional
    right to protection from violence. 1
    We review de novo the district court’s decision to grant summary judgment.
    E.g., Lindsey v. Hyler, 
    918 F.3d 1109
    , 1113 (10th Cir. 2019) (citing Trask v.
    Franco, 
    446 F.3d 1036
    , 1043 (10th Cir. 2006) (“On appeal, we review the award
    of summary judgment based on qualified immunity de novo.”)). Summary
    judgment becomes appropriate when there exists no genuine dispute of material
    fact, such that the moving party is entitled to judgment as a matter of law. 
    Id.
    (citing Fed. R. Civ. P. 56(a)).
    In conducting this exercise, we consider evidence and draw inferences in
    the manner most favorable to the non-moving party. 
    Id.
     (citing Schutz v. Thorne,
    
    415 F.3d 1128
    , 1132 (10th Cir. 2005)). But where, as here, a defendant asserts
    qualified immunity, the plaintiff must also demonstrate that (1) the defendant
    violated a constitutional right, and (2) the constitutional right was “clearly
    established” at the time the violation transpired. 
    Id.
     (citing Medina v. Cram, 252
    1
    I do not dispute that the officers acted negligently, but our precedent
    mandates that negligent conduct cannot form the basis for relief under § 1983.
    See, e.g., Davidson v. Cannon, 
    474 U.S. 344
    , 347 (1986) (citing Daniels v.
    Williams, 
    474 U.S. 327
     (1986)).
    -3-
    F.3d 1124, 1128 (10th Cir. 2001)). Unless the plaintiff can satisfy both
    requirements, the defendant will prevail.
    We examine each requirement in turn.
    A. Constitutional Violation
    The Supreme Court has explained that “the treatment a prisoner receives
    . . . and the conditions under which he is confined are subject to scrutiny under
    the Eighth Amendment.” 2 Helling v. McKinney, 
    509 U.S. 25
    , 31 (1993). The
    Court has accordingly construed the Eighth Amendment’s prohibition against
    “cruel and unusual punishments” to encompass certain “restraints on prison
    officials.” Farmer v. Brennan, 
    511 U.S. 825
    , 832 (1994). For example, officials
    may not apply “excessive” physical force against inmates. 
    Id.
     (citing Hudson v.
    McMillian, 
    503 U.S. 1
     (1992)).
    The Supreme Court has likewise held that the Eighth Amendment imposes
    certain affirmative obligations upon prison officials. Among these obligations are
    provisions for “adequate food, clothing, shelter, and medical care.” 
    Id.
     (citing
    2
    At the time of the assault, A.L. was a pretrial detainee, rather than a
    convicted prisoner. We accordingly consider this lawsuit under the Fourteenth
    Amendment’s provision for due process, although the Eighth Amendment’s
    prohibition against “cruel and unusual punishments” guides our analysis. E.g.,
    Perry v. Durborow, 
    892 F.3d 1116
    , 1121 (10th Cir. 2018) (citing Lopez v.
    LeMaster, 
    172 F.3d 756
    , 759 n.2 (10th Cir. 1999) (“Pretrial detainees are
    protected under the Due Process Clause rather than the Eighth Amendment. In
    determining whether [pretrial detainee’s] rights were violated, however, we apply
    an analysis identical to that applied in Eighth Amendment cases . . .”)).
    -4-
    Hudson v. Palmer, 
    468 U.S. 517
    , 526–27 (1984)). Most importantly for present
    purposes, the Court has held that prison officials “must take reasonable measures
    to guarantee the safety of [] inmates [].” 
    Id.
     (citing same).
    To the extent prison officials manifest deliberate indifference to any of
    these affirmative obligations, injured parties may seek redress under § 1983. E.g.,
    Estelle v. Gamble, 
    429 U.S. 97
    , 104–06 (1976). But this cause of action does not
    imply that “every injury suffered by one prisoner at the hands of another will
    translate into constitutional liability for prison officials responsible for the
    victim’s safety.” Farmer, 
    511 U.S. at 834
     (cleaned up).
    To prevail on a constitutional claim for “deliberate indifference,” a plaintiff
    must demonstrate both an objective and a subjective failure on the part of prison
    officials. Id; see also Smith v. Cummings, 
    445 F.3d 1254
    , 1258 (10th Cir. 2006)
    (“[T]he plaintiff must show that he is incarcerated under conditions posing a
    substantial risk of serious harm, the objective component, and that the prison
    official was deliberately indifferent to his safety, the subjective component.”).
    1. Objective Inquiry
    Where a § 1983 action is premised “on a failure to prevent harm, the inmate
    must show that he is incarcerated under conditions posing a substantial risk of
    serious harm.” See id. (citations and internal quotation marks omitted); see also
    Howard v. Waide, 
    534 F.3d 1227
    , 1236 (10th Cir. 2008) (“First, the alleged
    -5-
    deprivation must be sufficiently serious under an objective standard. In cases
    involving a failure to prevent harm, this means that the prisoner must show that
    the conditions of his incarceration present an objective substantial risk of serious
    harm.” (emphasis added) (citing Smith, 
    445 F.3d at 1258
    )).
    And where the plaintiff alleges deliberate indifference to the threats
    inmates may pose to one another, he must demonstrate a connection between the
    conditions of incarceration and the substantial (and particularized) risk of serious
    harm. See, e.g., Verdecia v. Adams, 
    327 F.3d 1171
    , 1175 (10th Cir. 2003) (“To
    establish a cognizable Eighth Amendment claim for failure to protect [an inmate
    from harm by other inmates], the plaintiff must show that he [was] incarcerated
    under conditions posing a substantial risk of serious harm[,] the objective
    component . . .”) (emphasis added) (citations and quotation marks omitted)). 3
    To the extent any cognizable risk arose from the circumstances the
    corrections officers faced in this case, it was the possibility that A.H., J.S., and
    J.V. might make good on their threats to assault A.L., if given the opportunity.
    The record, however, discloses that corrections officers separated the detainees
    3
    In analogous circumstances, we have held that substantial risk of serious
    harm may exist “where prison officials disregard repeated warnings of danger to a
    particular prisoner and continually refuse to make the situation safer, for example
    by [] separating the prisoner from other inmates who previously have attacked
    him on multiple occasions.” Grimsley v. MacKay, 
    93 F.3d 676
    , 681 (10th Cir.
    1996) (emphases added) (citations omitted).
    -6-
    from one another and from A.L. by imposing “pre-disc” requirements on A.H.,
    J.S., and J.V. immediately upon their first and only threats to A.L. Corrections
    officers accordingly restricted the movements of A.H., J.S., and J.V., such that
    they were not permitted any contact with A.L., one another, or other detainees.
    Such defensive action on the part of the corrections officers cannot be
    characterized as objective disregard of substantial risk of serious harm. 4
    It is, of course, true that—despite these precautions—Officer Casado left
    the control panel unlocked when A.H. exited his cell to shower. And that doing
    so—whether consciously or not, and whether A.H. knew the panel was unlocked
    or not—created some risk that A.H. might access the control panel, despite the
    presence of two additional corrections officers nearby and the absence of any
    other detainees in the common area.
    It is likewise true these circumstances created some risk that A.H. might
    somehow coordinate with J.S. and J.V.—who were segregated from one another
    upstairs—to unlock A.L.’s cell. And that none of the three corrections officers
    present would intervene before some combination of A.H., J.S., and J.V. made
    4
    Judge Baldock concludes the plaintiff has satisfied her burden to
    demonstrate an objective and substantial risk of serious harm. But in reaching
    that conclusion, he insists that reasonableness requires protective measures
    sufficient to “ensure A.L.’s safety.” Concurring & Dissenting Op. at 14. The
    failure to prevent harm, however, cannot on its own establish an objective
    disregard of substantial risk. Put another way, Judge Baldock’s conclusion relies
    on the fact of the assault to establish its likelihood.
    -7-
    good on their threats against A.L. In my view, however, this cascade of unlikely
    events should not overshadow the countervailing reality that corrections officers
    responded swiftly and decisively to the sole incidence of threats directed against
    A.L. by imposing “pre-disc” on A.H., J.S., and J.V.
    Given the unlikelihood that A.H.—while subject to “pre-disc”—would
    successfully access the unlocked control panel in the presence of three corrections
    officers, I would describe the risk these circumstances posed to A.L. as
    attenuated, rather than substantial. I would accordingly conclude the plaintiff has
    failed to demonstrate the requisite substantial risk of serious harm to carry her
    burden under the objective component of our inquiry.
    2. Subjective Inquiry
    I would also conclude the corrections officers lacked awareness of the facts
    necessary to infer subjective knowledge of this risk. Our subjective inquiry
    requires that prison officials manifest actual knowledge of facts from which an
    inference could be drawn regarding the existence of a substantial risk. Farmer,
    
    511 U.S. at 837
    . The Supreme Court has likewise emphasized that prison
    officials must actually draw the appropriate inference. 
    Id.
     at 837–38 (“[A]n
    official’s failure to alleviate a significant risk that he should have perceived but
    did not, while no cause for commendation, cannot under our cases be condemned
    as the infliction of punishment.”).
    -8-
    As a threshold observation, the record discloses nothing to suggest the
    corrections officers actually drew the inference of substantial risk to A.L. To be
    sure, the record certainly suggests some level of negligence. Taken as a whole,
    however, the fact that three officers allowed A.H.—and only A.H.—outside of his
    cell while the control panel remains unlocked does not satisfy the subjective
    inquiry’s requirement of actual knowledge.
    As Judge Carson’s concurring opinion acknowledges, and as Judge Baldock
    argues in his partial dissent, the case against Sergeant Luna is strongest, on
    account of his firsthand experience with at least one prior incident of
    unauthorized access. 5 But even if Sergeant Luna or the others were familiar with
    these incidents, I do not believe we can conclude they actually drew the inference
    of substantial risk to A.L. For one, all of these incidents transpired more than a
    5
    The record discloses four incidents involving the control panel in the
    eighteen months that preceded this assault. Two of these cases—October 2014
    and February 2015, respectively—apparently involved detainees taunting
    corrections officers. In the latter instance, the incident report lists Sergeant Luna
    as the supervising officer. Two other incidents—November 2014 and January
    2015, respectively—bear greater similarity to the circumstances of this case.
    In November 2014, one detainee lured the sole corrections officer present to a
    nearby closet on the pretext of retrieving a mop so that a second detainee could
    access the control panel and unlock cells occupied by a third co-conspirator and
    their eventual victim. The third detainee then attacked the victim in his newly-
    unlocked cell. In January 2015, a single detainee somehow accessed the control
    panel to unlock another detainee’s cell. It is not clear whether any of the cases
    involved detainees in pre disc.
    -9-
    year before the attack on A.L. Moreover, only two of them actually involved
    detainee-on-detainee violence.
    From what best I can discern from the record, both incidents involved
    readily-distinguishable factual circumstances. In the first incident, one detainee
    lured the duty officer to a nearby closet on pretext of retrieving a mop so that a
    second detainee could access the control panel and unlock cells occupied by a
    third co-conspirator and their eventual victim. Notwithstanding a superficial
    resemblance, several significant differences undermine the connection between
    this incident and the assault on A.L. As a condition of “pre-disc,” A.H. was the
    sole detainee permitted in the common area. And three corrections officers—as
    opposed to just one—observed his movements from their perch, just yards away
    from the commissary kiosk and the control panel.
    The record discloses fewer specifics about the details of the second
    incident. But we know a single detainee somehow accessed the control panel to
    unlock another detainee’s cell. And that he attacked the second detainee. The
    record does not disclose whether other detainees were present within the common
    area, or how many, if any, corrections officers might have been supervising the
    detainees. For these reasons, I would conclude the same logic that undermines
    the applicability of the previous incident to the assault on A.L. applies to this
    incident.
    -10-
    None of these distinctions should excuse the non-constitutional significance
    of these incidents. Whenever a detainee—particularly a juvenile—suffers
    violence at the hands of another detainee, it is important for the facility to
    identify and to address whatever underlying issues may have contributed to that
    harm. By the same token, we must acknowledge that not every wrong will sound
    in constitutional right and remedy. And—in part because these prior incidents
    present distinguishable factual circumstances—I cannot infer subjective
    knowledge of the supposed substantial risk these circumstances posed to A.L.
    To the extent, moreover, that we did infer subjective knowledge, Ms.
    Contreras has provided no evidence to suggest the corrections officers actually
    reached that inference. Even if I shared the conviction that reasonable corrections
    officers should have inferred A.H.’s plans from two previous incidents that
    transpired more than a year prior to these events, the Supreme Court has
    emphasized that the Eighth Amendment requires more than ordinary recklessness:
    “[W]e cannot accept petitioner’s argument . . . that a prison official who was
    unaware of the substantial risk of harm to an inmate may nevertheless be held
    liable under the Eighth Amendment if the risk was obvious and a reasonable
    prison official would have noticed it.” See Farmer, 
    511 U.S. at
    841–42 (emphasis
    added). Said simply, we do not require corrections officers to read minds.
    -11-
    Although the corrections officers sought to protect A.L. from harm, it
    seems likely that negligence undermined their efforts. Negligence offers much
    cause for concern here; but precedent tells us it cannot elicit constitutional
    intervention. See, e.g., Berry v. City of Muskogee, 
    900 F.2d 1489
    , 1495–96 (10th
    Cir. 1990) (observing that deliberate indifference requires a greater degree of
    fault than negligence or gross negligence). To be clear, the facility likely could
    have addressed the risk of detainee-on-detainee violence more effectively. But
    we must abide by the Supreme Court’s mandate to assess both objective risk and
    subjective awareness of that risk.
    The subjective inquiry requires that we ask whether the officers knew of a
    substantial risk and consciously disregarded the dangers that risk posed to A.L. I
    cannot infer subjective knowledge of any substantial risk to A.L. from this record.
    And no evidence indicates the corrections officers manifested the requisite actual
    knowledge of this risk, in any event. I would accordingly conclude that Ms.
    Contreras has failed to carry her burden.
    B. Clearly Established Law
    Even if we were to conclude a constitutional violation had occurred, the
    circumstances of this case nonetheless cannot satisfy the rigorous standards the
    Supreme Court has articulated for clearly established law. A “clearly established
    right is one that is sufficiently clear that every reasonable official would have
    -12-
    understood that what he is doing violates that right.” Mullenix v. Luna, 
    136 S. Ct. 305
    , 308 (2015) (citations and quotation marks omitted).
    We need not “require a case directly on point,” but the Supreme Court has
    cautioned that “existing precedent must have placed the statutory or constitutional
    question beyond debate.” 
    Id.
     (citations and quotation marks omitted). This is
    because qualified immunity is meant to “protect[] all but the plainly incompetent
    or those who knowingly violate the law.” 
    Id.
     (citations and quotation marks
    omitted). The Supreme Court has repeatedly instructed lower courts “not to
    define clearly established law at a high level of generality.” 
    Id.
     (citations and
    quotation marks omitted).
    As the Court has likewise emphasized “[t]he dispositive question is whether
    the violative nature of particular conduct is clearly established.” 
    Id.
     (citations
    and quotation marks omitted) (emphasis in original). Such an inquiry “must be
    undertaken in light of the specific context of the case, not as a broad general
    proposition.” 
    Id.
     (citations and quotation marks omitted) (emphasis added).
    Ms. Contreras frames the constitutional violation at a high level of
    generality: “[A] known but disregarded threat to an inmate’s physical safety,
    combined with evidence of prior assaults and information about a specific threat
    can establish deliberate indifference.” Aplt. Br. 21. As a threshold matter, I
    -13-
    doubt this formulation can satisfy the rigorous standards for specificity required
    by the Supreme Court. 6 See Mullenix, 
    136 S. Ct. at 308
    .
    But even if—for the sake of argument—we take this rule as given, the two
    Tenth Circuit authorities cited most extensively by Ms. Contreras, Berry v. City of
    Muskogee, 
    900 F.2d 1489
     (10th Cir. 1990), and Howard v. Waide, 
    534 F.3d 1227
    (10th Cir. 2008), do not yield fair notice of a constitutional violation in this case.
    In Berry, we held that a reasonable jury could conclude corrections officers
    had manifested deliberate indifference to the prospect of violence when one
    inmate was murdered by two others he had testified against at trial. 
    900 F.2d at 1498
    . Several observations readily distinguish this case from Berry. For one, the
    corrections officers in Berry took no action upon learning of the potential threat
    posed by the inmate’s co-defendants. In this matter, by contrast, corrections
    officers placed all three aggressors onto “pre-disc” immediately upon their first
    and only threats to A.L.
    Moreover, in Berry the perpetrators freely roamed the facility to access the
    murder weapon—a wire from a broom stored in a common area—under the
    6
    As Judge Carson acknowledges, we have previously applied a “sliding
    scale” analysis to determine whether clearly established law prohibits official
    conduct. I share his reservations regarding the “sliding scale” approach, given
    recent guidance from the Supreme Court. See also Mark. D. Standridge, Requiem
    for the Sliding Scale: The Quiet Ascent—and Slow Death—of the Tenth Circuit’s
    Peculiar Approach to Qualified Immunity, 
    20 Wyo. L. Rev. 43
     (2020).
    -14-
    nominal supervision of just one corrections officer. Id. at 1497. In this case—on
    account of the “pre-disc” precautions we have already discussed—A.H. was
    permitted outside of his cell only when other detainees were locked securely
    within theirs. And only then when not one, but three officers were present to
    oversee his activities. In our view, Berry cannot clearly establish a constitutional
    violation under the circumstances we now consider.
    In Howard, we reversed the district court’s decision granting summary
    judgment to corrections officers who failed to intervene when a newly-transferred
    inmate complained that members of the same prison gang who sexually abused
    him at a prior facility once again had begun to threaten him. 
    534 F.3d at
    1241–42. The inmate was sexually assaulted three times before corrections
    officers acted on his request to be relocated to a facility that did not contain
    members of this gang. 
    Id.
     at 1233–34.
    In my view, the same central observation that distinguished this case from
    Berry applies with equal force to Howard. Here, corrections officers placed all
    three aggressors onto “pre-disc” lockdown as soon as they threatened A.L. Of
    course, Sergeant Luna, Officer Casado, and Cadet Platero should have been more
    attentive. Perhaps more suspicious, too. And certainly less distracted by the
    television. But we cannot ascribe constitutional significance to their negligence.
    -15-
    Both Berry and Howard clearly establish that credible threats merit
    reasonable response. These authorities do not, however, demand perfection under
    the challenging circumstances that corrections officers often confront; for the
    Supreme Court has observed that “not . . . every injury suffered by one prisoner at
    the hands of another [will] translate into constitutional liability.” Farmer, 
    511 U.S. at 834
     (cleaned up).
    The out-of-circuit authorities cited by Ms. Contreras fare little better. In
    Erickson v. Holloway, 
    77 F.3d 1078
    , 1080 (8th Cir. 1996), an inmate accessed an
    electronic control panel only after corrections officers left the room that housed
    the panel entirely unattended for six minutes. Given the Supreme Court’s
    insistence that we contemplate “the specific context of [this] case,” a world of
    difference separates the facts of Erickson from the situation we confront. See
    Mullenix 
    136 S. Ct. at 308
    . After all, Sergeant Luna, Officer Casado, and Cadet
    Platero never left the common room unattended for any period of time.
    The same problem undermines Ms. Contreras’ reliance upon Street v.
    Corrs. Corp. of Am., 
    102 F.3d 810
     (6th Cir. 1996). In that case, a corrections
    officer—using an electronic control panel—opened every door in the unit after
    one inmate had threatened to assault another. See 
    id.
     at 813–14. The inmate
    made good on this threat, and the Sixth Circuit reversed the district court’s
    decision granting summary judgment to the corrections officer. 
    Id. at 816
    . In this
    -16-
    case, by contrast, Sergeant Luna, Officer Casado, and Cadet Platero imposed and
    enforced a regime of “pre-disc” lockdown against A.H. and his co-conspirators
    that sought to mitigate the risks all three aggressors might pose to A.L.
    Nor does the final authority Ms. Contreras cites extensively, Junior v.
    Anderson, 
    724 F.3d 812
     (7th Cir. 2013), clearly establish a constitutional
    violation under these circumstances. In that case, a corrections officer all but
    ignored the revelation that two cells that should have been secured remained
    unlocked. See 
    id.
     at 813–14. After an inmate who should have been secured in
    one of these cells subsequently joined several others in attacking another prisoner,
    the Seventh Circuit reversed the district court’s decision granting summary
    judgment to the corrections officer, who had also abandoned her post for at least
    fifteen minutes. See id. at 815.
    In my view, the same differences that distinguish Erickson and Street from
    “the specific context of [this] case” also diminish the significance of Junior. See
    Mullenix 
    136 S. Ct. at 308
    . Although the record discloses that Officer Casado
    and Cadet Platero may have realized that the control panel remained unsecured,
    only one detainee—A.H., who was subject to “pre-disc” lockdown—was present
    in the common area. And all three corrections officers remained just steps away
    from their charge, as well as the electronic control panel.
    -17-
    It is, of course, true that some “constitutional violation[s] may be so
    obvious that similar conduct seldom arises in our cases,” such that “it would be
    remarkable if the most obviously unconstitutional conduct should be the most
    immune from liability only because it is so flagrantly unlawful that few dare its
    attempt.” Lowe v. Raemisch, 
    864 F.3d 1205
    , 1210–11 (10th Cir. 2017) (citations
    and quotation marks omitted). But we have construed this functional exception to
    the presumption against fair notice quite narrowly, as we must effectively
    conclude “our precedents render the legality of the conduct undebatable.” See 
    id.
    at 1211 (citing Aldaba v. Pickens, 
    844 F.3d 870
    , 877 (10th Cir. 2016)). This is
    not such a case.
    In sum, no authorities clearly establish a constitutional violation under
    these circumstances.
    III. Conclusion
    For the reasons previously articulated, I would affirm the district court’s
    decision to grant summary judgment in this matter.
    -18-
    18-2176, Contreras v. Dona Ana Board of County Commissioners
    CARSON, J., Concurring in part and concurring in the judgment
    Make no mistake. We expect corrections officers to protect those under their
    supervision—especially children. The officers here—more attuned to a television show
    than the juveniles in their charge—allowed violent inmates to brutally assault A.L. I find
    their failure to protect A.L. inexcusable. But 
    42 U.S.C. § 1983
     provides no remedy to
    Plaintiff for unprofessional or negligent conduct. Instead, Plaintiff may only recover
    against the officers if they violated a clearly established constitutional right. We begin,
    therefore, by determining whether Plaintiff has met her burden.
    Plaintiff credibly argues that the officers’ conduct violated A.L’s constitutional
    rights. She presents a strong case against the supervisor—Officer Luna. After all, he
    knew that inmates previously accessed the control panel to commit violence against one
    another. But the other officers did not share Luna’s prior knowledge. So the case against
    them is not so clear.
    Even so, I would not reach the constitutional question because, even if the officers
    violated A.L’s constitutional rights, those rights were not clearly established. When our
    body of caselaw contains no case with remarkably similar facts, we look to a “sliding
    scale” analysis to determine whether clearly established law prohibited an officer’s
    conduct. Casey v. City of Fed. Heights, 
    509 F.3d 1278
    , 1284 (10th Cir. 2007). Under
    the sliding scale, the worse the conduct given prevailing constitutional principles, the less
    specificity is required from prior caselaw to clearly establish the violation. 
    Id.
    Some recent decisions suggest the sliding scale approach may conflict with current
    Supreme Court authority, but no case has overruled it. See Lowe v. Raemisch, 
    864 F.3d 1205
    , 1211 n.10 (10th Cir. 2017) (noting our sliding scale approach may allow us to find
    a clearly established right even when a precedent is neither on point nor obviously
    applicable); Aldaba v. Pickens, 
    844 F.3d 870
    , 874 n.1 (10th Cir. 2016). With no case
    overruling it, the sliding-scale approach lives in this Circuit. But that said, we must apply
    it cautiously as contemporary Supreme Court cases require an ever-increasing level of
    factual similarity for prior decisions to place a statutory or constitutional question beyond
    debate.1 Mullenix v. Luna, 
    136 S. Ct. 305
    , 308 (2015) (emphasizing that Court has
    repeatedly told lower courts not to define clearly established law at a high level of
    generality).
    I view this case as exceedingly close on both prongs of the qualified immunity
    analysis. Ultimately, however, I conclude the precedents from this Circuit and the
    Supreme Court do not place the constitutional question beyond debate (even considering
    the sliding scale approach). Plaintiff’s claims must therefore fail against the individual
    officers. So I join Chief Judge Tymkovich’s opinion as far as it addresses the “clearly
    established” prong of the qualified immunity analysis. Because I would not reach the
    1
    The Supreme Court has remanded at least one case we decided under the sliding
    scale approach for further consideration of whether the relevant body of law “clearly
    established” a constitutional question. Pickens v. Aldaba, 
    136 S. Ct. 479
     (2015).
    Although we originally decided the sliding scale warranted finding a right “clearly
    established,” on remand we determined our prior caselaw did not sufficiently mirror the
    factual circumstances of the case to sustain that finding. Aldaba, 844 F.3d at 879.
    2
    constitutional question, I join neither Judge Baldock’s nor Judge Tymkovich’s well-
    presented analysis of that issue.
    That leaves Plaintiff’s Monell claim against the Board. The district court
    determined that Plaintiff’s claim against the Board failed as a matter of law because she
    did not satisfy the third element for municipal liability—deliberate indifference. The
    district court determined that the Board could not be deliberately indifferent to a
    constitutional right unless the right is clearly established. See, e.g., Arrington-Bey v.
    City of Bedford Heights, 
    858 F.3d 988
    , 994 (6th Cir. 2017). And because the district
    court found the right was not clearly established, it ruled the Board could not have been
    deliberately indifferent to A.L.’s rights. I agree.
    Whether a municipal policymaker can be liable for deliberate indifference to a
    constitutional right that has not yet been established is an interesting one. And the
    answer depends on the type of claim alleged against the municipality. Consider first a
    claim based directly on a municipal act such as the termination of a municipal employee
    without due process. In that case, “the violated right need not be clearly established
    because fault and causation obviously belong to the city.” Arrington-Bey, 858 F.3d at
    994–95.
    But then consider a claim based on a municipality’s failure to properly train its
    employees. There, the theory stems from the municipality’s failure to teach its
    employees not to violate a person’s constitutional rights. In that posture, the
    “municipality’s alleged responsibility for a constitutional violation stems from an
    employee’s unconstitutional act [and the municipality’s] failure to prevent the harm must
    3
    be shown to be deliberate under ‘rigorous requirements of culpability and causation.’”
    Id. at 995 (quoting Bd. of Cty. Comm’rs of Bryan Cty. v. Brown, 
    520 U.S. 397
    , 415
    (1997)). Thus, the violated right in a failure to train case “must be clearly established
    because a municipality cannot deliberately shirk a constitutional duty unless that duty is
    clear. 
    Id.
     The Second, Sixth, and Eighth Circuits have each reached this conclusion.
    Townes v. City of New York, 
    176 F.3d 138
    , 143–44 (2d Cir. 1999); Arrington-Bey, 858
    F.3d at 995; Szabla v. City of Brooklyn Park, 
    486 F.3d 385
    , 393 (8th Cir. 2007) (en
    banc).
    Judge Baldock believes that in application this means the district court
    inappropriately granted the Board qualified immunity. I agree that municipalities cannot
    invoke the doctrine of qualified immunity. Owen v. City of Independence, 
    445 U.S. 622
    ,
    624–25 (1980) (holding that municipalities cannot assert the doctrine of qualified
    immunity). But this case differs remarkably from Owen. Owen arose from a claim of
    deliberate municipal indifference where the municipality directly caused the
    constitutional injury. 
    Id. at 633
    . Here, by contrast, Plaintiff advances a failure to train
    theory in which she “must show not only that an employee’s act caused a constitutional
    tort, but also that the city’s failure to train its employees caused the employee’s violation
    and that the city culpably declined to train its ‘employees to handle recurring situations
    presenting an obvious potential for such a violation.’” Arrington-Bey, 858 F.3d at 995
    (citing Brown, 
    520 U.S. at 409
    ). The Supreme Court’s statement “obvious potential for
    such a violation” requires that the constitutional violation be obvious (i.e., clearly
    established). Requiring that the right be clearly established in this context does not give
    4
    qualified immunity to municipalities; it simply follows the Supreme Court’s demand
    “that deliberate indifference in fact be deliberate.” Arrington-Bey, 858 F.3d at 995
    (citing Szabla, 
    486 F.3d at 394
    ).
    Plaintiff alleged the County engaged in deliberate indifference by failing to
    adequately train its correction officers. For the reasons discussed above, however,
    Plaintiff’s claim must fail because she cannot show the right the Board violated was
    obvious. I would therefore affirm the district court’s order granting summary judgment
    to the Board on the Monell claim. I thus concur in the judgment on the Monell claim,
    although on a different ground than Chief Judge Tymkovich who concluded no
    constitutional violation occurred.
    For these reasons, I respectfully concur in part and concur in the judgment.
    5
    18-2176, Contreras v. Doña Ana Board of County Commissioners
    BALDOCK, Circuit Judge, concurring in part, dissenting in part.1
    Corrections officers cannot absolutely guarantee the safety of those in their care.
    Nor does the Constitution sweep so broadly as to require every cell in a detention center to
    always remain locked for the protection of its guests. But after violent threats have been
    made by a group of particularly violent detainees, any reasonable official cognizant of his
    duty to protect would know that the failure to secure the control panel while a would-be
    assailant is outside his cell is objectively unreasonable.
    As my colleagues accurately point out, qualified immunity protects “all but the
    plainly incompetent.” Concurring Op. at 13 (Tymkovich, C.J.) (quoting Mullenix v. Luna,
    
    136 S. Ct. 305
    , 308 (2015) (per curiam)). Because Sergeant Luna’s conduct was plainly
    incompetent, qualified immunity should afford him no shelter. And because Doña Ana
    County Detention Center (DACDC) was deliberately indifferent to a pattern of tortious
    conduct by its employees, it cannot be shielded from liability on the ground that A.L.’s
    asserted constitutional right was not clearly established. For these reasons, I would reverse
    the district court’s grant of summary judgment to Sergeant Luna and the DACDC and
    remand for further proceedings. I therefore respectfully dissent.
    1
    The parties have my apologies for the delay in issuing this decision. Unfortunately,
    too many cases in our civil justice system today drag on for far too long. My colleagues
    and I strive to counteract this lamentable trend by efficiently resolving appeals. But
    sometimes we fail, and it is the parties who must bear the burden of our shortcomings.
    I.
    The historical facts relevant to this appeal, unlike the inferences to be drawn from
    them, are undisputed.2 On the evening of May 3, 2016, officials booked A.L., then fourteen
    years old, into the DACDC after he allegedly violated his probation by disregarding his
    curfew. At the time of A.L.’s detention, the three juveniles responsible for the forthcoming
    attack on him, J.V., J.S., and A.H., were also detained at the DACDC. All three juveniles
    had exhibited disciplinary problems just days and hours prior to their attack on A.L.
    On April 25, 2016, for example, J.S. attacked another juvenile detainee in the
    dayroom “by punching him several times in the face.” Three other detainees were soon
    attacking the victim as well. J.S. stated he attacked the victim because he “had been talking
    shit the day before.” DACDC officials placed J.S. on “pre-disciplinary lockdown” (pre-
    disc) for his aberrant behavior.
    A.H was also placed on pre-disc on April 22. A DACDC caseworker’s notes on
    A.H. indicate that on April 25 “[p]er Sgt. Luna[,] [A.H.] is not able to go to medical for lab
    draw due to inmate being aggressive and uncooperative with staff at this time. Per Sgt.
    Luna[,] ‘it is not safe to take [A.H.] out of his cell.’ Will continue to monitor.” As reflected
    by a psychiatrist’s evaluation report, A.H. believed he had an “anger problem” and that
    “people [were] wanting to get [him].” A.H. stated: “I go off on everyone when I get mad.”
    2
    To properly analyze whether Plaintiff has carried her burden to withstand the
    defense of qualified immunity at the summary judgment stage, one must begin by
    considering all material facts contained in the record. Chief Judge Tymkovich
    conspicuously discounts, among other things, recent past incidents in the DACDC juvenile
    pod where detainees accessed the control panel and the three assailants’ known violent
    tendencies—in particular those of A.H.
    2
    When A.H. was taken off pre-disc on April 30 and allowed to leave his cell, he
    wasted no time in yelling out “it’s time to get on lockdown again.” Moments later,
    A.H. approached a table in the dayroom where J.V. sat with J.S. and said something
    to J.S. At this point, J.V. and A.H. began to argue. J.V. then stood up and “went
    towards [A.H.] and began punching him in the face and head with closed fists. [A.H.]
    . . . punched back with closed fists.” After officers separated the two miscreants and
    medical staff cleared A.H., he returned to the dayroom. There, A.H continued his
    disruptive behavior by yelling “obscenities and gang slurs toward [J.V.],” causing yet
    another fight. J.V. reported the fight broke out because “[A.H.] kept talking ‘shit’ to
    him and . . . went after him.” As a result of their altercation, both J.V. and A.H. were
    placed on pre-disc.
    Following lockdown around 9:30 p.m. on May 3, the evening before the attack
    on A.L., the three soon-to-be assailants, all fresh off pre-disc, once again became
    disruptive. J.V. began banging on his cell door, broke his county-issued cup and
    deodorant stick, and covered his cell window with his mattress and sheets. Even after
    the officer on duty uncovered J.V.’s window, he continued to bang and kick on his
    door.    Around 10:15 p.m., J.S. and A.H. joined J.V. and began kicking on their cell
    doors. The juveniles refused to discontinue their disruptive behavior.
    Around 10:22 p.m., officials brought A.L. into the juvenile pod’s dayroom. The
    dayroom is surrounded by two levels of individual cells. J.V., J.S., and A.H. were housed
    separately on the pod’s second level. When A.L. entered the dayroom, the trio began
    yelling at A.L., telling him they were going to “fuck him up.” A.L. was placed in a cell on
    3
    the second level near the others. As a result of their disruptive behaviors and threats, J.V.,
    J.S., and A.H. were again placed on pre-disc. While on pre-disc, the three juveniles were
    to be confined to their cells except when they were individually permitted to engage in
    recreation time, shower, use the phone, and access the commissary kiosk. None of the
    three were allowed out of their cells while any one of the others or A.L. was out of his cell.
    Shortly after 9:00 a.m. the next morning, A.H., still on pre-disc, was alone
    outside his cell. He had just finished showering in the shower room located on the
    north side of the dayroom. Consistent with their placement on pre-disc the night
    before, J.V. and J.S. remained locked in their cells, as did A.L. Defendants, Sergeant
    Luna, Officer Casado, and Cadet Platero, were sitting at tables in the juvenile pod’s
    dayroom watching television.         Officer Casado, who had been employed at the
    DACDC for just over a year, was the assigned dayroom officer. Sergeant Luna, the
    supervising officer, had been employed at the DACDC for twenty-three years. Cadet
    Platero had been employed at the DACDC for just over two months.
    All three Defendants knew J.V., J.S., and A.H. had threatened to assault A.L. the
    night before and were on pre-disc as a result. The record is unclear as to whether Casado
    or Platero were aware of the precise nature of the trio’s recent disciplinary problems at the
    DACDC, but Defendants’ response brief tells us they knew the three were “generally
    violent.” The brief also tells us Sergeant Luna knew the three had “histories of assault at
    DACDC.” And Sergeant Luna specifically was aware, as illustrated by the caseworker’s
    April 25 notes on A.H., that A.H. was a problem and not to be trusted outside his cell.
    4
    Located on the juvenile pod’s west wall in front of where the individual
    Defendants were sitting was a commissary kiosk. Five to ten feet left of the kiosk,
    on a podium referred to as the “Officers’ Platform Station,” was a control panel used
    to electronically lock and unlock the juvenile pod’s cell doors.   The control panel is
    a touchscreen device that allows an officer to lock or unlock individual cell doors
    with the touch of a button after entry of a security code or password. Officers may
    log off or lock the panel with the touch of a button rendering it ineffective until
    someone with a security code once again logs in.
    The closest thing in the record to a written DACDC policy about locking the
    control panel is found in a code of ethics contained in the “Standard Operating
    Procedures” manual for the DACDC. The code provides:
    A.     If an officer is going to leave his workstation, it must
    either be locked or the officer must log off.
    B.     If an officer happens to come upon a workstation that was
    left open and unlocked by another user, it is the officer’s
    responsibility to log that user off and log in under their
    username and password if they are going to use it.
    After showering, A.H. asked Sergeant Luna for permission to access the
    commissary kiosk. Sergeant Luna granted permission. On a security tape, one sees
    J.V. and J.S. standing in their second-level cells watching events transpire in the
    dayroom. As A.H. approached the kiosk, he looked over his shoulder to see if any of
    the Defendants were paying attention. They were watching TV. When A.H. sensed
    5
    his opportunity, he approached the control panel, which he obviously suspected might
    be unlocked (he was right), and proceeded to open J.V.’s, J.S.’s, and A.L.’s cell doors.
    J.V. and J.S. immediately exited their cells and ran into A.L.’s neighboring cell,
    closing the door and causing it to lock behind them. Making good on their threats, J.V.
    and J.S. began to beat A.L.     A.H. avoided Officer Casado’s pursuit, ran up the stairs,
    and locked himself in his own cell while the chaos ensued. Sergeant Luna and Officer
    Casado ran upstairs to A.L.’s cell. Cadet Platero opened A.L.’s cell from the control
    panel down below. When J.V. and J.S. refused to stop beating A.L., Sergeant Luna
    doused the two with pepper spray. A.L. was transported to the hospital. As a result
    of the attack, he suffered a broken jaw, was rendered unconscious, and was left
    bleeding from both ears.
    The day after the attack on A.L., Lieutenant Mendoza of the DACDC’s Professional
    Standards Unit interviewed Sergeant Luna and Officer Casado. Officer Casado said this
    about securing the control panel in the juvenile pod:
    [Casado] did confirm that the control panel can be locked if needed
    but that he does not remember if he locked it in this instance. He stated
    that he believes nobody on his shift logs off from the panel as normal
    practice when he walks away from the officers’ podium. He stated that
    since he has been assigned to juvenile . . . he has never been directed
    to log off the panel. He did confirm that he was the last person at the
    officers’ podium before the incident occurred.
    Sergeant Luna disagreed with Casado, however, when Mendoza questioned him
    about control panel procedures in the juvenile pod:
    I questioned [Sgt. Luna] regarding whether or not officers on his shift
    are locking the control panel when they locate themselves away from
    the podium. He stated that it is common practice for staff on his shift
    6
    to lock the panel but that he was not watching to see if Casado locked
    it in this instance. He stated that he has to assume that Casado would
    have locked it as other officers do, but he does not stand next to all
    officers each time they move away from the podium. He stated that
    ever since juvenile had been moved to the adult side, there was never
    a directive given to him about locking the panel although it was
    getting done.
    Rather than submitting to an interview the day after the incident, Cadet Platero
    drafted a memorandum in which she indicated that “when she observed Officer Casado
    get up from his post at the officers’ podium to sit at the table, she noticed that he did
    not lock the control panel that opens each cell in the dayroom.” During an interview
    with Lieutenant Mendoza about three weeks after the incident, Platero confirmed that
    she witnessed “Officer Casado walk away from the officers’ podium without locking
    the control panel.”
    Notably, in an affidavit executed two months after the attack on A.L., Officer
    Casado changed his story. Casado now attests that during his training at the DACDC,
    he was “specifically” told (I wonder by whom) that the policy of the DACDC was to
    log out of the control panel after he used it, rendering the control panel ineffective until
    someone with a security code once again logged in. Casado says he was “never”
    instructed nor allowed to leave the control panel unlocked.
    Cadet Platero similarly attests that during her training she was instructed (I
    wonder by whom) on the use of the control panel: “I was trained that I should always
    lock or log out of a control panel before leaving it. Before the incident, I saw Casado
    leave the control panel unlocked which I knew to be a policy violation, but I did not alert
    anyone.” Sergeant Luna attests that he instructs all officers under his supervision “to lock
    7
    all pods’ control panels, including the juvenile pod.” Sergeant Luna states he has “never”
    instructed a cadet or detention officer to leave the control panel unlocked at the DACDC;
    nor is he aware of any other sergeants or supervising officers ever having done so.
    Importantly, A.H.’s unauthorized use of the unlocked control panel was not the first
    time a detainee at the DACDC had improperly accessed the control panel in the juvenile
    pod’s dayroom. Juvenile detainees had accessed the control panel on at least four prior
    occasions beginning in October 2014, or about eighteen months prior to the attack on A.L.
    On October 25, 2014, a detainee insisted on crossing his body over the “red line” in front
    of the control panel. After being warned, the detainee again crossed the red line and leaned
    his body against the control panel. As a result, DACDC officials placed him on pre-disc.
    The fourth incident was much like the first. On February 12, 2015, a juvenile detainee at
    the DACDC “kept crossing the red line and laying [his] hands on the control panel.” When
    the detainee crossed the line and touched the control panel a second time, he too was placed
    on pre-disc. The incident report lists Sergeant Luna as the juvenile pod’s supervising
    officer at the time of this infraction.
    Unfortunately, the second and third incidents involving a juvenile detainee’s
    unauthorized access to the control panel were not so harmless. The similarities between
    those two incidents and the incident at issue are substantial. Less than a month after the
    first incident, on November 23, 2014, a juvenile detainee asked the officer on duty to
    retrieve a mop from the dayroom closet. When the officer did so, a second detainee
    accessed the dayroom’s control panel, which was unlocked, and opened the cells of a third
    and fourth detainee. The third detainee then ran from his unlocked cell into the unlocked
    8
    cell of the fourth detainee and attacked him. After order had been restored, an assisting
    officer was escorting the third detainee to booking when he saw him toss a white object
    toward the trash can. The object was a sharpened portion of a toothbrush designed for use
    as a weapon.
    A third incident occurred on January 20, 2015. On that date, a juvenile detainee
    attacked another detainee in the latter’s cell. The assailant told officials that “he went
    towards the officers’ desk, crossed the red line and opened the other detainee’s cell by
    pushing a button on the dayroom [control] panel.” The assailant admitted he went into the
    victim’s cell and threw the first punch because the victim had called him a “snitch.”
    According to the incident report, both detainees were placed on pre-disc and the “dayroom
    panel was disabled due to this incident.” When the control panel in the juvenile pod again
    became operational is unclear from the record—certainly too soon from A.L.’s perspective.
    II.
    To survive summary judgment as to Defendants’ individual liability under § 1983,
    Plaintiff must show (1) sufficient evidence exists for a factfinder to conclude one or
    more of the individual Defendants violated A.L.’s constitutional right to due process
    by failing to protect him from violence at the hands of other detainees, and (2) this right
    was clearly established at the time of the violation. Matthews v. Bergdorf, 
    889 F.3d 1136
    , 1143 (10th Cir. 2018). Because the individual Defendants assert the defense of
    qualified immunity, the burden is on Plaintiff to establish her right to proceed against each
    Defendant individually. 
    Id.
     at 1144–45. Plaintiff has undoubtedly carried this burden with
    respect to her claim against Sergeant Luna.
    9
    A.
    In determining whether A.L.’s constitutional rights were violated, we must view the
    evidence in the light most favorable to Plaintiff and refrain from resolving factual disputes
    in favor of the individual Defendants (i.e., the parties seeking summary judgment). See
    McCoy v. Meyers, 
    887 F.3d 1034
    , 1044–45 (10th Cir. 2018). When all the evidence is
    properly considered under this standard, a reasonable jury could find Sergeant Luna was
    deliberately indifferent to the substantial risk of harm with which J.V., J.S., and A.H. had
    threatened A.L.
    1.
    The point of departure for our inquiry into whether any of the individual
    Defendants caused A.L. to suffer a constitutional deprivation is the Supreme Court’s
    decision in Farmer v. Brennan, 
    511 U.S. 825
     (1994). Farmer established that the Eighth
    Amendment’s prohibition against cruel and unusual punishment imposes a duty on
    officials to provide prisoners with “humane conditions of confinement.” 
    Id. at 832
    .
    Prison officials who are aware of a substantial risk to an inmate’s safety have a duty to
    protect the inmate from harm and therefore must take reasonable steps to guarantee his
    safety. 
    Id.
     at 832–33.
    But of course, absent a formal adjudication of guilt against A.L., the Eighth
    Amendment has no application.         Bell v. Wolfish, 
    441 U.S. 520
    , 535 n.16 (1979).
    Nevertheless, “[i]n evaluating the constitutionality of conditions . . . of pretrial detention
    that implicate only the protection against deprivation of liberty without due process of law,
    . . . the proper inquiry is whether those conditions amount to punishment of the detainee.”
    10
    
    Id. at 535
    . To determine whether the evidence is sufficient for a jury to find any or all of
    the individual Defendants “punished” A.L. and deprived him of liberty without due process
    of law in violation of the Fourteenth Amendment, Tenth Circuit precedent requires us to
    employ an analysis identical to the analysis we employ in Eighth Amendment cases
    challenging a prisoner’s conditions of confinement under a failure-to-protect theory. Perry
    v. Durborow, 
    892 F.3d 1116
    , 1121 (10th Cir. 2018); cf. Wolfish, 
    441 U.S. at
    546 n.28
    (finding “no reason” to distinguish between pretrial detainees and convicted inmates in
    reviewing a correctional center’s security practices).
    Before a jury may find an individual Defendant violated A.L.’s right to due
    process, Plaintiff must satisfy two elements: one objective and one subjective.
    Farmer, 
    511 U.S. at 834
    . To satisfy the objective component, Plaintiff must show
    A.L. was detained “under conditions posing a substantial risk of serious harm.” 
    Id.
    If Plaintiff satisfies this objective prong, she must then establish that at least one of
    the individual Defendants was deliberately indifferent to the substantial risk A.L.
    faced. 
    Id.
     This is a subjective inquiry. 
    Id.
    While “deliberate indifference entails something more than mere negligence, . . .
    it is satisfied by something less than acts or omissions for the very purpose of causing
    harm or with knowledge that harm will result.” 
    Id. at 835
    . “[T]he official must both
    be aware of facts from which the inference could be drawn that a substantial risk of
    serious harm exists, and he must also draw the inference.” 
    Id. at 837
    . “[A]n official’s
    failure to alleviate a significant risk that he should have perceived but did not, while
    11
    no cause for commendation, cannot . . . be condemned as the infliction of punishment.”3
    
    Id. at 838
    . In short, “deliberate indifference is equivalent to recklessness in this
    context.” Smith v. Cummings, 
    445 F.3d 1254
    , 1258 (10th Cir. 2006).
    2.
    On this record, viewing the evidence in the light most favorable to Plaintiff, a
    reasonable jury could conclude that A.L. faced an “objective ‘substantial risk of
    serious harm.’” Howard v. Waide, 
    534 F.3d 1227
    , 1236 (10th Cir. 2008) (quoting
    Farmer, 
    511 U.S. at 834
    ). When DACDC officials escorted A.L. to his cell the night
    before the attack, three juvenile detainees with very recent histories of disciplinary
    3
    In Kingsley v. Hendrickson, 
    135 S. Ct. 2466
     (2015), the Supreme Court held
    an objective reasonableness standard governs excessive force claims brought by
    pretrial detainees under the Fourteenth Amendment. In Castro v. Cty. of Los
    Angeles, 
    833 F.3d 1060
     (9th Cir. 2016) (en banc), the Ninth Circuit imaginatively
    interpreted Kingsley and held an objective standard also governs failure-to-protect
    claims of pretrial detainees raised under the Fourteenth Amendment. And In
    Darnell v. Pineiro, 
    849 F.3d 17
     (2d Cir. 2017), the Second Circuit followed suit.
    For years, however, federal courts across the land, including the Tenth Circuit, have
    relied on Wolfish to apply Farmer’s subjective deliberate-indifference standard to
    claims that state actors failed to protect pretrial detainees in violation of the
    Fourteenth Amendment. See, e.g., Lopez v. LeMaster, 
    172 F.3d 756
    , 759 n.2 (10th
    Cir. 1999); Walton v. Dawson, 
    752 F.3d 1109
    , 1117–18 (8th Cir. 2014). To suggest
    Kingsley overturned such long-standing precedent, uninvited and sub silentio,
    simply proves too much. Absent the Supreme Court overturning its own precedent
    or our own, we are bound by it. And I suspect the Court may never do so because,
    as Judge Ikuta ably points out in her dissent to Castro, a fundamental difference
    exists between the action underlying an excessive force claim and the inaction
    underlying a deliberate-indifference claim: “[A] person who unknowingly fails to
    act—even when such a failure is objectively unreasonable —is negligent at most.
    And the Supreme Court has made clear that ‘liability for negligently inflicted harm
    is categorically beneath the threshold of constitutional due process.’” Castro, 833
    F.3d at 1086 (Ikuta, J., dissenting) (quoting Kingsley, 
    135 S. Ct. at 2472
    ).
    12
    problems involving violent encounters at the DACDC, and housed in close proximity
    to A.L., directly threatened to “fuck him up” while raising a ruckus. As a result, the
    three juveniles, each of whom could turn violent with little warning, had been placed
    on pre-disc precisely to alleviate a substantial risk of serious harm to A.L.,
    themselves, and others.
    According to Defendants and Chief Judge Tymkovich, these circumstances did
    not present a substantial risk of harm because the juvenile assailants were placed on pre-
    disc and three corrections officers were present—physically, at least—in the dayroom
    when the attack occurred. Based on these “precautions,” Defendants maintain that an
    unsecured control panel cannot, as a matter of law, result in § 1983 liability for failure
    to protect A.L. What this conclusion conveniently fails to acknowledge is this: A.H.
    was one very troubled and volatile miscreant on the loose within easy reach of an
    unlocked control panel. That panel provided ready access to J.V.’s, J.S.’s, and A.L.’s
    cells. And those cells were located upstairs in close proximity to one another but at a
    distance from Defendants downstairs, who were charged with the duty to protect A.L.
    Because the kiosk and control panel were in such close proximity, and J.V.’s,
    J.S.’s, and A.L.’s cells were far removed from the control panel, a dozen DACDC guards
    in the dayroom watching TV would not have prevented A.H. from rushing the control
    panel and pushing the few buttons necessary to unlock the cell doors and facilitate the
    attack on A.L. After all, what did A.H. have to lose? Another placement on pre-disc?
    The facts well illustrate that A.H. could not have cared less whether he was on pre-
    disc. He was on pre-disc repeatedly. Under these circumstances, branding the attack
    13
    on A.L. as the culmination of a “cascade of unlikely events” and labeling the risk
    he faced as “attenuated,” see Concurring Op. at 7–8 (Tymkovich, C.J.), wholly ignores
    both the reality of the situation presented and the reality of involuntary detention.
    Defendants further argue the fact the three assailants, after threatening A.L., had
    been placed on pre-disc with its accompanying restrictions illustrates reasonable
    measures were taken to avert the attack. The question, however, is not whether placing
    the three miscreants on pre-disc was a reasonable thing to do.     It surely was given the
    trio’s recent unruly and violent behavior at the DACDC. But pre-disc is nothing more
    than a label. Its terms must be enforced by reasonable and appropriate measures.
    The central question here is whether the individual Defendants acted reasonably
    by leaving the control panel unsecured given the circumstances described above. Placing
    the three juveniles on pre-disc and “segregating” them from each other and A.L. could
    not alone ensure A.L.’s safety if such segregation was not maintained through the
    implementation of reasonable measures such as securing the cell doors.                 “In
    determining whether prison officials acted reasonably, we consider what actions they
    took, if any, as well as available alternatives that might have been known to them”—
    like securing the juvenile pod’s control panel precisely because the assailants were on
    pre-disc for threatening A.L. with bodily harm.      Howard, 
    534 F.3d at 1240
    .
    A.H. was a known problem with a recent history of violent outbursts at the DACDC.
    In fact, just one week before the attack on A.L., Sergeant Luna reported it was not safe to
    take A.H. out of his cell. Half measures—such as sitting in the juvenile pod watching TV
    near an unlocked control panel while A.H. wandered the dayroom—availed A.L. nothing.
    14
    Defendants’ delayed reactions when A.H. rushed the control panel, as the video of the
    incident shows, belies any claim that the corrections officers “observed his movements
    from their perch[.]” See Concurring Op. at 7–8 (Tymkovich, C.J.).
    Just as the effectiveness of prison segregation depended on keeping cell door keys
    out of the hands of would-be assailants prior to advances in technology, the effectiveness
    of the segregation in this case depended on the control panel being locked and
    inaccessible—a wholly unremarkable proposition. As Defendants admit in their brief:
    “Excluding the unlocked control panel and [A.H.’s] access to it, DACDC’s preventative
    discipline and supervision were reasonable.” (emphasis added). With that much I agree.
    Thus, I would conclude that Plaintiff has created a triable issue as to whether the individual
    Defendants disregarded the substantial risk of serious harm A.L. faced “by failing to take
    reasonable measures to abate it.” See Farmer, 
    511 U.S. at 847
    .
    3.
    The next question is whether a reasonable jury could find any of the individual
    Defendants recklessly disregarded the risk of serious harm to A.L when the control panel
    was left unlocked and accessible to A.H. on the morning of the attack. A jury cannot decide
    a detention center official’s failure to protect a victim amounted to deliberate indifference
    if they preliminarily find he or she failed to perceive the significant risk of harm to the
    victim, no matter how objectively obvious. 
    Id. at 838
    . Where the risk is obvious such that
    a reasonable person would realize it, a jury certainly may infer that a defendant did in fact
    realize it. 
    Id. at 842
    . Such an inference cannot be conclusive, however, “for we know that
    15
    people are not always conscious of what reasonable people would be conscious of.” 
    Id.
    (quoting 1 W. LaFave & A. Scott, Substantive Criminal Law § 3.7, p. 335 (1986)).
    Although it is an extremely close call, I would conclude that Plaintiff has failed to
    carry her burden on the subjective prong with respect to Officer Casado and Cadet Platero.
    To be sure, sufficient evidence exists to conclude these Defendants knew they were
    required to keep the control panel locked when not in use. Cadet Platero also knew that
    Officer Casado’s failure to secure the panel was a violation of DACDC policy because she
    was trained (who trained her she does not say) to lock the panel before leaving it. And of
    course, any reasonable person would realize it is unsafe to leave a control panel unlocked
    in a juvenile detention center at any point—much less after violent threats have been made.
    But what is missing from the calculus is evidence that these junior officers were
    aware of facts from which the inference could be drawn, and also drew the inference, that
    leaving the control panel unlocked posed a serious risk of harm to A.L. See id. at 837–
    38. Nothing suggests, for example, that either of these corrections officers were aware of
    the past incidents at the DACDC where detainees accessed the unsecured control panel and
    opened the cell doors to attack other detainees. Although Officer Casado and Cadet Platero
    indisputably acted negligently—and, in my view, with gross negligence—their
    nonfeasance ultimately falls short of deliberate indifference.
    The same cannot be said for Sergeant Luna, however. Based on the conflicting
    record evidence, a jury could infer that Sergeant Luna was aware the control panel was
    unlocked at the time of the attack on A.L because it was routinely unlocked. Such an
    inference arises from (1) Defendant Casado’s statements (in direct conflict with Sergeant’s
    16
    Luna’s statements) that he believed nobody on his shift ever logged off the control panel
    in the juvenile pod and he had never been trained or directed to do so; (2) Defendant
    Platero’s statement that she witnessed Casado move away from the control panel without
    locking it just prior to the attack but said or did nothing; (3) the “pervasive” factual dispute,
    as recognized by the district court, surrounding DACDC control panel protocol or lack
    thereof; and (4) A.H.’s decision to access the panel the morning of the attack.
    A reasonable jury could further infer that, as a DACDC sergeant with supervisory
    responsibilities and direct knowledge of one prior incident, Luna was aware of past
    problems surrounding operation of the control panel in the juvenile pod. On two previous
    occasions within the past eighteen months, juvenile detainees accessed an unlocked control
    panel in order to precipitate attacks on other detainees—the same unfortunate scenario we
    face here. Notably, the second of these two incidents prompted DACDC officials to disable
    the control panel in the juvenile pod for an unspecified time period. Sergeant Luna must
    have known that the control panel in the juvenile pod was disabled for a time precisely
    because of these attacks given his supervisory position at the DACDC. Moreover, Sergeant
    Luna was the supervising officer in the juvenile pod on a subsequent occasion when a
    detainee approached the control panel and, as a result, was placed on pre-disc.
    The past incidents involving the control panel at the DACDC cannot be dismissed
    as too remote from and dissimilar to the facts presented here to bear on Sergeant Luna’s
    state of mind. It is true that the first incident involved two detainees outside their cells,
    whereas A.H. was the sole detainee permitted in the dayroom at the time of the attack on
    A.L. But this begs the question: How many juvenile detainees does it take to access an
    17
    unsecured control panel and push a button or two? If past incidents at the DACDC are any
    indication, two may be better, but one is enough.
    Indeed, the January 20, 2015 incident involved a single detainee who accessed the
    control panel, opened another detainee’s cell, and then proceeded to assault his fellow
    detainee in the latter’s cell. Because the record does not provide any additional details,
    Chief Judge Tymkovich attempts to discount this incident by summarily “conclud[ing] the
    same logic that undermines the applicability of the previous incident to the assault on A.L.
    applies to this incident.” Concurring Op. at 10 (Tymkovich, C.J.). Properly viewing the
    evidence in the light most favorable to Plaintiff, however, leads to the opposite
    conclusion—that is, the similarities between this incident and the incident at issue are
    substantial. See McCoy, 887 F.3d at 1044–45 (explaining we must consider the facts and
    all inferences in the light most favorable to the party asserting the injury).
    Last, but not least, don’t forget about Sergeant Luna’s particular knowledge
    regarding A.H.’s violent propensities. Recall that Sergeant Luna specifically was aware,
    as illustrated by the DACDC caseworker’s April 25 notes, that A.H. was especially
    dangerous and could not be trusted outside his cell. Yet, rather than keep an eye on A.H.
    while he roamed free in the dayroom, Sergeant Luna decided to watch TV. Based on
    Sergeant Luna’s delayed reaction after A.H. accessed the control panel, there must’ve been
    a good show on that morning.
    As John Adams once reminded us: “Facts are stubborn things; and whatever may
    be our wishes, inclinations, or the dictates of our passions, they cannot alter the state of the
    facts and evidence.” John Bartlett, Familiar Quotations 380 (15th ed. 1980). Given
    18
    Sergeant Luna’s knowledge of past incidents involving the control panel and the particular
    risk A.H. posed outside his cell—combined with all the other material facts in the record—
    Luna’s mental state at the time of the attack is within the province of a jury, not this
    Court.     For these reasons, I would conclude Plaintiff has carried her burden of
    demonstrating Sergeant Luna was deliberately indifferent to A.L.’s safety and violated his
    constitutional right to protection from violence.
    B.
    This brings me to the second part of our qualified-immunity analysis.          My
    colleagues conclude that Sergeant Luna is entitled to qualified immunity even if he violated
    the Constitution because A.L.’s asserted constitutional right was not clearly established at
    the time of the violation. Respectfully, I remain unpersuaded.
    1.
    Whether Sergeant Luna may be held liable for his wrongdoing at this point
    turns on the “objective legal reasonableness” of his conduct assessed in light of (1)
    the factual context of this case and (2) the legal rules that were “clearly established”
    at the time of the attack. White v. Pauly, 
    137 S. Ct. 548
    , 552 (2017) (per curiam)
    (facts); Anderson v. Creighton, 
    483 U.S. 635
    , 639 (1987) (rules). Sergeant Luna has
    nothing to worry about if his “actions could reasonably have been thought consistent
    with the [rules] [he] [is] alleged to have violated.” Anderson, 
    483 U.S. at 638
    .
    In every case, we first look for a Supreme Court or Tenth Circuit decision on point
    to determine whether the legal rule under which a plaintiff seeks to hold a defendant liable
    is clearly established. Cordova v. Aragon, 
    569 F.3d 1183
    , 1192 (10th Cir. 2009). Absent
    19
    any such decision, we consider whether the clearly established weight of authority from
    our sister circuits holds the rule to be as the plaintiff maintains. 
    Id.
     Neither the Supreme
    Court nor this Court, however, has ever required “the very action in question” to have
    “previously been held unlawful.” Anderson, 
    483 U.S. at 640
    ; Halley v. Huckaby, 
    902 F.3d 1136
    , 1149 (10th Cir. 2018) (“[A] prior case need not be exactly parallel to the conduct
    here for the officials to have been on notice of clearly established law.”). Instead, “in the
    light of pre-existing law the unlawfulness must be apparent.” Anderson, 
    483 U.S. at 640
    .
    To be sure, prior decisions involving similar facts provide strong support for a
    conclusion that the law was clearly established. This is why, in most cases, “like”
    decisions are necessary before we reach such a conclusion. They are not necessary
    in every case, however, because the Supreme Court has told us that “general
    statements of the law are not inherently incapable of giving fair and clear warning”
    to reasonable persons. Hope v. Pelzer, 
    536 U.S. 730
    , 741 (2002) (quoting United
    States v. Lanier, 
    520 U.S. 259
    , 271 (1997)).
    Hope recognized that “a general constitutional rule already identified in the
    decisional law may apply with obvious clarity to the specific conduct in question,
    even though ‘the very action in question has not previously been held unlawful.’” 
    Id.
    (quoting Lanier, 
    520 U.S. at 271
    ). Such recognition was possible because, in Hope,
    the Court “shifted the qualified immunity analysis from a scavenger hunt for prior
    cases with precisely the same facts toward the more relevant inquiry of whether the
    law put officials on fair notice that the described conduct was unconstitutional.”
    Pierce v. Gilchrist, 
    359 F.3d 1279
    , 1298 (10th Cir. 2004) (McConnell, J.).
    20
    Accordingly, qualified immunity should not be granted “if government defendants
    fail to make reasonable application of the prevailing law to their circumstances.” 
    Id.
    (internal quotations omitted).
    While “like cases” undoubtedly bear upon “fair notice,” the relevant standard in
    ascertaining “clearly established law” is the latter, not the former. The qualified-
    immunity standard simply does not call for a “single level of [rule] specificity sufficient
    in every instance.” Hope, 
    536 U.S. at 740
     (quoting Lanier, 
    520 U.S. at 271
    ); see also
    Cordova, 
    569 F.3d at 1192
    . Rather, the precedent on which a court relies to conclude
    the law was clearly established need only “be clear enough that every reasonable
    official would interpret it to establish the particular rule the plaintiff seeks to apply.”
    Dist. of Columbia v. Wesby, 
    138 S. Ct. 577
    , 590 (2018) (emphasis added).
    Throughout the development of the “clearly established law” standard, the Supreme
    Court has stressed that the specificity of the rule is especially important in Fourth
    Amendment cases. See, e.g., City of Escondido v. Emmons, 
    139 S. Ct. 500
    , 503 (2019)
    (per curiam) (excessive force); Kisela v. Hughes, 
    138 S. Ct. 1148
    , 1153 (2018) (per curiam)
    (same); Wesby, 
    138 S. Ct. at 590
     (unlawful arrest); Mullenix v. Luna, 
    136 S. Ct. 305
    , 308
    (2015) (per curiam) (excessive force). The concerns associated with defining clearly
    established law “at a high level of generality” is most salient in the Fourth Amendment
    context due to the imprecise nature of the relevant legal standards and how such standards
    apply in rapidly evolving circumstances. Mullenix, 
    136 S. Ct. at 308
    ; see also Wesby, 
    138 S. Ct. at 590
    . This is particularly true in excessive force cases because “officers are often
    forced to make split-second judgments—in circumstances that are tense, uncertain, and
    21
    rapidly evolving—about the amount of force that is necessary in a particular situation.”
    Kisela, 
    138 S. Ct. at 1152

    Because every § 1983 case does not sit at one end of a spectrum or the other, we
    have recognized, based on what the Supreme Court has told us, that the degree of
    specificity required from prior caselaw depends on the character of the challenged
    conduct. Pierce, 
    359 F.3d at 1298
    . Thus, in Browder v. City of Albuquerque, we
    explained that “[i]n deciding the ‘clearly established law’ question, [the Tenth Circuit]
    employs a ‘sliding scale’ under which ‘the more obviously egregious the conduct in light
    of prevailing constitutional principles, the less specificity is required from prior case
    law to clearly establish the violation.’”         
    787 F.3d 1076
    , 1082 (10th Cir. 2015)
    (Gorsuch, J.) (quoting Shroff v. Spellman, 
    604 F.3d 1179
    , 1189–90 (10th Cir. 2010)).
    My colleagues’ reservations about our sliding-scale approach comes as no surprise
    given the Supreme Court’s recent qualified-immunity decisions. The Court’s slew of
    per curiam reversals in the past five years—nearly all of which concern the use of excessive
    force—appears to have most circuit courts tiptoeing around qualified immunity’s clearly
    established prong. But as Judge Carson recognizes: “With no case overruling it, the
    sliding-scale approach lives in this Circuit.” Concurring Op. at 2 (Carson, J.). Until either
    this Court or the Supreme Court sounds the death knell for our sliding-scale approach, we
    are bound to apply it rather than merely pay lip service to it.4
    4
    In Lowe v. Raemisch, 
    864 F.3d 1205
    , 1211 n.10 (10th Cir. 2017), we questioned
    whether our sliding-scale approach conflicted with Supreme Court precedent post Hope.
    “The possibility of a conflict arises because the sliding-scale approach may allow us to find
    a clearly established right even when a precedent is neither on point nor obviously
    22
    2.
    With this understanding of the applicable standard in mind, let’s consider whether
    Sergeant Luna is entitled to qualified immunity. Four decades ago, this Court held that
    the Constitution imposes a duty on corrections officers to take reasonable measures to
    protect inmates under their charge from violence at the hands of other inmates. Ramos v.
    Lamm, 
    639 F.2d 559
    , 572–74 (10th Cir. 1980). Then in Farmer, decided in 1994, the
    Supreme Court clarified the contours of this rule, holding that a breach of this duty violates
    the Constitution where a corrections officer “knows that inmates face a substantial risk of
    serious harm and disregards that risk by failing to take reasonable measures to abate it.”
    
    511 U.S. at 847
    .
    No one can reasonably dispute post Farmer and its progeny that once Sergeant Luna
    learned of the substantial risk of harm to A.L from the assailants’ threats and subjectively
    perceived such threats, he had a duty to take reasonable measures to protect A.L. Thus,
    the rule under which Plaintiff seeks to hold Sergeant Luna liable is just this: When a
    detention center officer knows a detainee faces a substantial risk of serious harm from
    applicable.” 
    Id.
     (emphasis added) (citing Aldaba v. Pickens, 
    844 F.3d 870
    , 874 n.1 (10th
    Cir. 2016)). But this brings us back to the point we made in Pierce: Should the second
    prong of qualified-immunity analysis turn solely on the results of a “scavenger hunt” for
    prior cases with the same facts, or should it focus on the “more relevant inquiry” of whether
    the law put reasonable officials on fair notice that the described conduct was
    unconstitutional? 
    359 F.3d at 1298
     (emphasis added). The majority apparently thinks the
    former. Only the Supreme Court, however, can definitively resolve this question. And as
    Lowe recognized, so far its precedents send us mixed signals. But one thing is certain: The
    Supreme Court has neither directly commented upon nor overruled our sliding-scale
    approach. The “possibility of a conflict” is simply not enough to conclude such an
    approach is no longer the law in this circuit.
    23
    another detainee yet fails to employ reasonable available measures to lessen the risk, the
    officer breaches his or her constitutional duty to protect the vulnerable detainee.
    But the fact a constitutional duty to protect arises in the face of an officer’s
    knowledge does not mean it is necessarily clear in every case, or even most cases,
    what reasonable measures consist of or, in other words, what such duty to protect
    specifically requires of the officer. See, e.g., Cox v. Glanz, 
    800 F.3d 1231
    , 1247 (10th
    Cir. 2015) (holding an inmate’s right to proper suicide screening procedures during
    booking was not clearly established). The salient question here is whether this rule
    was sufficiently specific in the factual context of this case to give Sergeant Luna fair
    warning that his failure to secure the control panel could give rise to constitutional
    liability. Mullenix, 
    136 S. Ct. at 308
     (explaining courts must undertake the clearly
    established inquiry in light of the specific context of the case).
    Here, viewing the facts in the light most favorable to Plaintiff, Sergeant Luna was
    aware: (1) J.V., J.S., and A.H. had been placed on pre-disc for collectively threatening A.L.
    less than twelve hours earlier; (2) the three assailants were generally unruly and willing to
    fight; (3) the three assailants were to be kept away from one another and from A.L. until
    further notice; (4) the three assailants would be allowed outside their cells daily but only
    with restrictions; (5) A.H. was outside his cell and in the dayroom just prior to the attack;
    (6) A.H. could not be trusted outside his cell; (7) the control panel securing the cells had
    been left unlocked; and (8) two incidents occurred in the juvenile pod in the past eighteen
    months where, to precipitate an attack, one detainee opened the cell door of another
    detainee from the unsecured control panel. See Tolan v. Cotton, 
    572 U.S. 650
    , 657 (2014)
    24
    (stressing need to view facts and draw inferences in favor of the nonmovant when deciding
    the clearly established prong). What Sergeant Luna effectively contests is whether a
    reasonable corrections officer under these circumstances would have understood the state
    of the law on the morning of the attack required him to ensure the control panel was locked.
    The constitutional question here is beyond “beyond debate.” Wesby, 138 S. Ct. at
    589. Mindful that qualified immunity does not protect “the plainly incompetent,” Kisela,
    
    138 S. Ct. at 1152
    , the unlawfulness of Sergeant Luna’s conduct in failing to secure the
    control panel follows immediately from the rule that corrections officers must employ
    reasonable measures to mitigate a known risk of serious harm to a threatened detainee.5
    “After all, some things are so obviously unlawful that they don’t require detailed
    explanation . . . .” Browder, 787 F.3d at 1082.
    The clearly established standard for determining whether an official has violated a
    detainee’s right to reasonable protection from a known risk of serious harm “is not
    extremely abstract or imprecise under the facts alleged here, but rather is relatively
    straightforward and not difficult to apply.” A.N. ex rel. Ponder v. Syling, 
    928 F.3d 1191
    ,
    5
    The circuit court case closest factually to the one at bar may be Erickson v.
    Holloway, 
    77 F.3d 1078
     (8th Cir. 1996). There, the defendant jail guard left the dayroom
    control panel unattended for about six minutes to make a routine check of the cell block.
    
    Id. at 1080
    . Contrary to jail policy, the defendant had not disabled the control panel to
    prevent inmates from operating the locks. 
    Id.
     While the defendant was away, an inmate
    opened the electronic lock to the recreation area allowing the assailant to access and beat
    the plaintiff. 
    Id.
     Nearly two decades later, the Eighth Circuit, citing cases from the Third,
    Seventh, Eighth, and Eleventh Circuits, commented that “prison officials have an
    obligation, in a variety of circumstances, to protect non-violent inmates from violent
    inmates by keeping cell doors locked.” Walton v. Dawson, 
    752 F.3d 1109
    , 1121 (8th Cir.
    2014) (emphasis added).
    25
    1198–99 (10th Cir. 2019); see also Pauly, 137 S. Ct. at 552 (explaining the requirement
    that clearly established law be “particularized to the facts of the case” is intended to shield
    officers from liability based on alleged violations of “extremely abstract rights”). Put
    differently, this rule is sufficiently specific to have put Sergeant Luna on notice that his
    failure to ensure the control panel was secure violated A.L.’s constitutional right to
    protection from violence at the hands of J.V., J.S., and A.H. Because any reasonable
    corrections officer in Sergeant Luna’s position would have known his conduct violated
    A.L.’s asserted right, Luna should not be entitled to qualified immunity.
    III.
    Finally, I turn to Defendant DACDC’s “municipal” liability. Plaintiff focuses her
    constitutional claim of municipal liability on a failure-to-train theory. To prevail against
    the DACDC under this theory, Plaintiff must show (1) a municipal employee committed a
    constitutional violation against A.L. and (2) a DACDC policy or custom was the moving
    force behind such violation. Cordova, 
    569 F.3d at 1193
    . As noted above, a jury could
    conclude that Sergeant Luna violated A.L.’s Fourteenth Amendment right to substantive
    due process. The question that remains, then, is whether a DACDC policy or custom was
    the moving force behind the underlying constitutional violation.
    A.
    In City of Canton v. Harris, the Supreme Court held § 1983 permitted a factfinder
    to hold a municipality liable for its failure to train employees. 
    489 U.S. 378
    , 380 (1989).
    The “critical question” before the Court was: “Under what circumstances can inadequate
    training be found to be a ‘policy’ that is actionable under § 1983?” Id. at 383. Identifying
    26
    conduct, or lack thereof, properly attributable to the DACDC is hardly enough to impose
    municipal liability on it. “Only where a municipality’s failure to train its employees in a
    relevant respect evidences a ‘deliberate indifference’ to the rights of its inhabitants can
    such a shortcoming be properly thought of as a . . . ‘policy or custom’ that is actionable
    under § 1983.” Id. at 389. When, like here, a plaintiff does not claim the municipality has
    directly inflicted a constitutional injury, as in the case of a facially unconstitutional policy,
    but has caused an employee to do so, “rigorous standards of culpability and causation must
    be applied” to ensure the municipality is not held vicariously liable for its employees’
    actions.”6 Bd. Of Cty. Commr’s v. Brown, 
    520 U.S. 397
    , 405 (1997).
    To establish a municipality’s deliberate indifference under a failure-to-train theory,
    a plaintiff usually must show a “pattern of tortious conduct.” Bryson v. City of Oklahoma
    City, 
    627 F.3d 784
    , 789 (2010). Decisionmakers’ “continued adherence to an approach
    they know or should know has failed to prevent tortious conduct by employees may
    establish the conscious disregard for the consequences of their action—the ‘deliberate
    indifference’—necessary to trigger municipal liability.” Brown, 
    520 U.S. at 407
    . In
    6
    Based on the record—in particular Sergeant Luna’s admission of supervisory
    authority in his personal affidavit and the failure of the DACDC to make any effort
    to rebut the same—Sergeant Luna was responsible for the operation of an unwritten
    discretionary policy in the juvenile pod regarding the securing of the control panel.
    Thus, at the time of the attack, Sergeant Luna possessed authority to establish
    municipal policy in the juvenile pod over use of the control panel. In Pembaur v.
    City of Cincinnati, the Supreme Court recognized that if a county board delegates its
    power to establish final policy to a delegatee, the delegatee’s decisions would
    represent county policy and could give rise to municipal liability. 
    475 U.S. 469
    , 483
    n.12 (1986). Notably, however, Plaintiff does not seek to hold the DACDC liable
    based on the theory that Sergeant Luna’s alleged wrongdoing was the DACDC’s
    wrongdoing.
    27
    addition, such a pattern “may tend to show that the lack of proper training, rather than a
    one-time negligent administration of the program or factors peculiar to the officer involved
    in a particular incident, is the ‘moving force’ behind the plaintiff’s injury.” Id. at 408.
    In Canton, however, the Supreme Court acknowledged “the possibility that
    evidence of a single violation of federal rights, accompanied by a showing that a
    municipality has failed to train its employees to handle recurring situations presenting an
    obvious potential for such a violation, could trigger municipal liability.” Brown, 520 U.S.
    at 1391; accord Canton, 
    489 U.S. at
    390 & n.10. Violent encounters between detainees
    “may be a highly predictable or plainly obvious consequence” of the DACDC’s failure to
    train its officials on the fundamentals necessary to address recurring situations like threats
    of violence or more specifically how, in the presence of such threats, to secure the control
    panel when not in use. Bryson, 
    627 F.3d at 789
    ; cf. Canton, 
    489 U.S. at
    396–97 (O’Connor,
    J., concurring in part) (recognizing a claim that officers were inadequately trained in
    diagnosing mental illness fell short of the kind of “obvious” need for training sufficient to
    show deliberate indifference). But we need not ask whether the attack on A.L., considered
    in a vacuum, is sufficient to sustain municipal liability. Here, we most certainly have a
    pattern of detainees improperly accessing the control panel in the juvenile pod sufficient to
    have placed the DACDC on notice that, sooner or later, its purported failure to train was
    “substantially certain to result in a constitutional violation.” Bryson, 
    627 F.3d at 789
    .
    The district court concluded Plaintiff failed to establish a pattern of tortious conduct
    surrounding the control panel and therefore DACDC officials would not have understood
    their failure to train officers on appropriate control panel protocol was substantially certain
    28
    to result in a constitutional violation. Nonsense. Detainees on four separate occasions
    within eighteen months of the attack on A.L. inappropriately accessed the control panel in
    the juvenile pod’s dayroom. Fortunately, on the first and fourth occasions no harm
    resulted. Nonetheless, DACDC officials placed the culprits on pre-disc precisely because
    they realized such conduct was unacceptable and wrought with peril. On the second and
    third occasions, neither DACDC officials nor targeted detainees were so fortunate. Rather,
    targeted detainees were ruthlessly attacked and beaten because the control panel had been
    left unlocked. These four occasions considered in the aggregate were sufficient to place
    DACDC officials on notice that an unsecured control panel in the juvenile pod may result
    in problems of constitutional proportions for the DACDC, making the questions of
    causation and deliberate indifference in this case for the jury.
    B.
    One final point deserves clarification. Relying on cases from our sister circuits, the
    district court alternatively concluded that because a failure-to-train claim requires a
    showing of deliberate indifference on the part of the DACDC, Plaintiff must also show the
    asserted right was clearly established at the time of the attack. See Arrington-Bey v. City
    of Bedford Heights, 
    858 F.3d 988
     (6th Cir. 2017); Szabla v. City of Brooklyn Park, 
    486 F.3d 385
     (8th Cir. 2007) (en banc); Townes v. City of New York, 
    176 F.3d 138
    , 143 (2d Cir.
    1999). Judge Carson accepts this approach. I have my doubts.
    To be sure, not all Monell claims are created equal. But neither are all failure-to-
    train theories. As explained above, the Supreme Court has distinguished deliberate-
    indifference claims based on “a pattern of tortious conduct by inadequately trained
    29
    employees” from those based on “evidence of a single violation of federal rights.” Brown,
    
    520 U.S. at
    407–09; Canton, 
    489 U.S. at
    390 & n.10. Brown’s statement regarding an
    “obvious potential for such a violation” concerned the latter. 520 U.S. at 409; see also id.
    at 402 (“We granted certiorari . . . to decide whether the county was properly held liable
    for respondent’s injuries based on Sheriff Moore’s single decision to hire Burns.”
    (emphasis added)); id. at 415–16 (concluding that “Bryan County is not liable for Sheriff
    Moore’s isolated decision to hire Burns without adequate screening” (emphasis added)).
    As this Court has explained, “deliberate indifference may be found absent a pattern
    of unconstitutional behavior if a violation of federal rights is a highly predictable or plainly
    obvious consequence of a municipality’s action or inaction.” Schneider v. City of Grand
    Junction Police Dep’t, 
    717 F.3d 760
    , 771 (10th Cir. 2013) (emphasis added; citation and
    brackets omitted). Conversely, when a deliberate-indifference claim is based on a pattern
    of tortious conduct by inadequately trained employees, a plaintiff need not also prove the
    underlying violation was obvious (i.e., clearly established). This is because the pattern of
    unlawful behavior puts a municipal policymaker on sufficient “notice that its action or
    failure to act is substantially certain to result in a constitutional violation[.]” 
    Id.
     Thus, a
    municipality can manifest deliberate indifference even when its employee (i.e., the
    individual defendant) did not violate clearly established law.
    The out-of-circuit authorities Judge Carson cites do not compel a contrary
    conclusion. In each of these cases, the plaintiff’s deliberate-indifference claim was based
    on evidence of a single violation of federal rights, not a pattern of past tortious conduct by
    municipal employees. See, e.g., Szabla, 
    486 F.3d at
    392–93 (“[T]his was a one-time
    30
    incident, and there is no evidence of a pattern of constitutional violations making it
    ‘obvious’ that additional training or safeguards were necessary.”); see also Arrington-Bey,
    858 F.3d at 990–92; Townes, 
    176 F.3d at 142
    . Indeed, Judge Colloton recognized this
    critical distinction in Szabla. 
    486 F.3d at
    392–93.
    Perhaps requiring the violated right to be clearly established is the proper approach
    when dealing with deliberate-indifference claims premised on an isolated constitutional
    violation. On the other hand, maybe not. Consider the following hypothetical, which is
    based on a recent Eleventh Circuit decision:
    A municipal policymaker arms its police officers with firearms because it knows
    the officers will sometimes need to arrest dangerous individuals. Yet, the municipality
    fails to train the officers regarding the lawful use of deadly force. During an investigation,
    an officer shoots a ten-year-old child lying on the ground within arm’s reach of the officer,
    while repeatedly attempting to shoot a pet dog that wasn’t posing any threat. The child’s
    mother sues the officer for excessive force and also brings a Monell claim against the
    municipality for its failure to train the officer. A court holds, as the Eleventh Circuit did,
    that the officer is entitled to qualified immunity because his actions did not violate any
    clearly established rights. See Corbitt v. Vickers, 
    929 F.3d 1304
    , 1323 (11th Cir. 2019)
    (“Because we find no violation of a clearly established right, we need not reach the other
    qualified immunity question of whether a constitutional violation occurred in the first
    place.”), cert. denied, No. 19-679, 
    2020 WL 3146693
     (U.S. June 15, 2020).
    Applying the rule Judge Carson champions today, does this also “spell the end of
    th[e] Monell claim” against the municipality? See Arrington-Bey, 858 F.3d at 995. If the
    31
    answer is “yes,” I fail to see how this deliberate-indifference standard doesn’t effectively
    afford a form of vicarious immunity to municipalities.         Cf. Hagans v. Franklin Cty.
    Sheriff’s Office, 
    695 F.3d 505
    , 511 (6th Cir. 2012) (“Because Ratcliff did not violate a
    clearly established right, it follows that his employer, the Franklin County Sheriff’s Office,
    is also entitled to summary judgment.”). In my view, these are dangerous waters. See
    Owen v. City of Independence, 
    445 U.S. 622
    , 650 (1980) (“[W]e can discern no
    ‘tradition so well ground in history and reason’ that would warrant the conclusion
    that in enacting [§ 1983], the 42nd Congress sub silentio extended to municipalities
    a qualified immunity based on the good faith of their officers.”).
    Fortunately, we have no occasion in this case to lay down a categorical rule one way
    or the other because Plaintiff’s deliberate-indifference claim against the DACDC is based
    on a pattern of tortious conduct by inadequately trained employees. Both the Supreme
    Court and this Court have unequivocally held such evidence may satisfy the deliberate-
    indifference element of a Monell claim. Brown, 520 U.S. at 407–08; Schneider, 717 F.3d
    at 771. Because that settles the issue before us, I would leave for another day the question
    whether a deliberate-indifference claim based on a single violation of federal rights
    necessarily requires the asserted right to be clearly established.
    IV.
    For the reasons stated above, I would affirm the district court’s decision to grant
    summary judgment to Defendants Casado and Platero, but I would reverse the judgment
    with respect to Sergeant Luna and the DACDC and remand for further proceedings.
    I respectfully dissent.
