    FOR THE DISTRICT OF COLUMBIA
    Dayshawn Ingram,
    Plaintiff,
    v.
    Michael Shipman-Meyer, et al.,:              Civil Action No. 12-1915 (GK)
    Defendants.
    MEMORANDUM OPINION
    Plaintiff is Dayshawn Ingram, the son of the decedent, Anthony
    Chambers.    Mr. Chambers died immediately after a violent encounter
    with   the   police.       Plaintiff    alleges     that    one    of   the    police
    officers,     Officer     Michael      Shipman-Meyer,       illegally         used   a
    chokehold on his father, which caused his death.                  Plaintiff brings
    several claims against Officers Shipman-Meyer, William Karabelas,
    Stephen Rose,     and Elizabeth LaDuca,          as well as the District of
    Columbia, stemming from the death of his father.
    Presently before the Court are Plaintiff's and Defendants'
    Cross-motions for Summary Judgment.              Having reviewed the parties'
    respective     Motions,      Oppositions,        Replies,     and       Surreplies,
    Plaintiff's Motion for Summary Judgment is denied in its entirety
    and Defendants' Motion for Summary Judgment is granted in part and
    denied in part.

    I .     BACKGROUND
    A. Procedural Background
    On September 19, 2012, Plaintiff commenced this action in the
    Superior        Court    of      the    District      of   Columbia.       Subsequently,
    Defendants removed the case from Superior Court to this Court,
    pursuant to 28          u.s.c.    §    1441 et seq.
    After extensive discovery, Plaintiff amended the Complaint he
    originally       filed     in     Superior     Court.       First    Amended      Complaint
    ("FAC")     [Dkt. No. 37].             Count One alleges that the four officers
    acted negligently,            violating an applicable national standard of
    care, resulting in Mr. Chamber's injury and death.                          FAC    ``    8-13.
    Count Two alleges that the officers committed assault and battery,
    resulting in in Mr.              Chamber's injury and death.               
    Id. `` 14-17.
    Count Three alleges              that    the officers used excessive force                  in
    violation of Mr. Chamber's constitutional rights.                          
    Id. `` 18-22.
    Count Four alleges that the officers engaged in tortious conduct,
    and thereby violated the District's wrongful death statute.                                
    Id. `` 23-25.
          Finally,           Count   Five    alleges      that   the     District
    negligently failed to train the officers in the proper use of
    chokeholds, resulting in Mr. Chamber's injury and death.                                
    Id. `` 26-32.
        Plaintiff seeks compensatory damages of $5,000,000 on each
    count.
    -2-
    On January 15,       2016,    Plaintiff moved        for   partial   summary
    judgment.     Pla1ntiff's Motion for Summary Judgment                ("Pl.'s MSJ")
    [Dkt. No. 56] .    Plaintiff seeks summary judgment on parts of Counts
    One, Two, Three, and Five of his First Amended Complaint, but does
    not seek summary judgment as to any part of Count Four.                      See 
    id. Plaintiff concedes
    that there is a genuine dispute as to whether
    or not the officers' actions caused the death of Mr. Chambers, and
    therefore that he cannot fully prevail on any of his claims at the
    summary judgment stage.          
    Id. at 25
    n.6.       Instead, he essentially
    asks the Court to hold that he is entitled to judgment on all the
    other elements necessary to succeed on those claims, leaving only
    the issue of causation for trial.                See 
    id. De£endants filed
    an
    Opposition.       Defendants'        Opposition   ("Defs.'     Opp'n")     [Dkt.   No.
    59] .
    The Defendants also cross-moved for summary judgment on all
    counts.    Defs.' MSJ at 1.      Plaintiffs filed an Opposition, to which
    Defendants    filed    a   Reply,      and    both parties     filed     Surreplies.

    Reply ("Defs.' Reply")        [Dkt. No. 65], Plaintiff's Surreply ("Pl.'s
    Surreply")     [Dkt.   No.     68],     and    Defendants'     Surreply      ("Defs.'
    Surreply")    [Dkt. No. 69].

    B. Factual Background
    1. The Court Will not Rely on Defendants' Statement of
    Undisputed Material Facts
    As   a   preliminary       matter,        Defendants        argue    that        their
    statement of material facts should be accepted, virtually in its
    entirety, because Plaintiff failed to comply with Local Rule 7.
    Defs.' Analysis of Material Facts, Exh. 1 to Defs.' Reply at 1 n.1
    (citing LCvR 7)       [Dkt. No.      65-1]       Defendants argue that,             if the
    Court were to do so,         there are essentially no material facts in
    dispute in this case.            Defs.'      Reply at 2 n.2.          In other words,
    Defendants      ask   the    Court    to      decide      this     case    based    almost
    exclusively on their characterization of what occurred.
    Local Rule 7 requires a party moving for summary judgment to
    file   a    "statement      of   material        facts"     that     it    contends       are
    undisputed.      LCvR 7(h) (1).       In addition, it requires that a party
    opposing a      summary judgment motion must                respond to the moving
    party's     statement of     facts     with      "a concise statement"             of    "all
    material facts" that remain in dispute.                   
    Id. Where the
    non-movant
    fails to "controvert" a statement of undisputed fact made by the
    movant, the Court may assume that the statement is admitted.                             Id.;
    see also Broady v. Zanzibar on the Waterfront, LLC, 
    576 F. Supp. 2d
    14, 16-17 (D.D.C. 2008).
    -4-
    Both Plaintiffs and Defendants                  filed    the    required Rule      7
    statement        with    their    respective motions          for    summary    judgment.
    Defendants, in their Opposition to Plaintiff's Motion for Summary
    Judgment, filed the required response to Plaintiff's statement of
    material facts,           indicating what facts Defendants believed remain
    in dispute.        Plaintiff failed to respond to Defendants' statement
    of material        facts     in his Opposition to Defendants'                  Motion for
    Summary Judgment.             Instead,       he simply resubmitted his original
    statement of material facts with only a few additional facts added.
    Given Plaintiff's failure to comply with Local Rule 7, Defendants
    argue that their statement of material facts should be admitted in
    its entirety.           See Defs.' Analysis of Material Facts                  (asserting
    that all but one of Defendants' statement of material facts not in
    dispute have been admitted by failure to comply with the local
    rule) .
    Though "strict compliance with the local rule" is the norm,
    Broady,     F.    Supp.      2d   at   16,    there   are   cases     in   which    it   is
    unwarranted.        See Hedgpeth v. Rahim, 
    2016 WL 5720699
    , *5-6 (D.D.C.
    October 3,        2016)      (refusing to admit Defendant's uncontradicted
    statement,       where     the    statement was       so biased that        it did not
    accurately       ref le ct    what     material     facts   were     and   were    not   in
    dispute).        This is one such case.
    -5-
    In cases     involving deadly force,           "where     the    witness most
    likely to contradict the officer's story -                the person [killed] -
    is unable to testify, courts                  . may not simply accept what may
    be a self-serving account by the police officer.                      Instead, courts
    must     carefully examine all         the    evidence   in the         record          to
    determine whether the officer's story is internally consistent and
    consistent with other known facts.                 Courts must also look at the
    circumstantial evidence that, if believed, would tend to discredit
    the police officer's story,            and consider whether this evidence
    could     convince    a     rational   factf inder     that     the     officer    acted
    unreasonably."        Flythe v. District of Columbia,                 
    791 F.3d 13
    , 19
    (2015)    (internal citations and quotation marks omitted).
    Heeding the di rec ti ve of          the Court of Appeals,          the Court
    carefully examined the evidence in the record to determine whether
    the account provided by Defendants, or any portions thereof, were
    contradicted by other record evidence.                  
    Flythe, 791 F.3d at 19
    .
    Having done so, the Court concludes that Defendants' Statement of
    Material     Facts    not    in   dispute     is   materially     inaccurate.           It
    presents - as undisputed - facts that Defendants'                       own witnesses
    contradict, and it omits facts that are inconvenient to its overall
    narrative.         Consequently,       the     Court   cannot      simply        rely   on
    Defendants' version of what occurred in deciding these Motions.
    -6-
    Instead,    the Court will present the relevant facts            it has
    culled from the record and then identify the key issues of material
    fact ~hat remain in dispute.
    2. Statement of Undisputed and Disputed Facts
    Anthony Chambers was 38 years old on June 8, 2012.           That day
    he was staying with his sister, Valentina Chambers.           Mr. Chambers
    was experiencing some sort of mental disturbance, possibly brought
    on by his use of PCP.      Seeking assistance, Mr. Chambers contacted
    the Mayor's office.
    Two employees of the Department of Behavioral Health ("DBH"),
    Linda Miller and Gary Yingling, were dispatched to the Chambers'
    residence to assist him.       Mr. Chambers appeared agitated, telling
    them that a chip had been planted inside him by the government.
    The DBH employees asked Mr. Chambers to accompany them so that he
    could receive treatment,       but he refused and then demanded that
    they leave. He threatened violence if they did not.
    Believing Mr. Chambers to be a potential danger to himself or
    others,   Miller and Yingling sought assistance from the police.
    They went   to   the   First   District   police   station,   where   Miller
    prepared a document authorizing the detention of Mr. Chambers for
    a psychiatric evaluation.       Given Mr. Chamber's size, he stood 6'
    4" tall and weighed more than 370 pounds, and prior behavior, they
    -7-
    ...
    asked that multiple officers accompany them to assist in detaining
    and transporting him.
    Four off ice rs were assigned the task -                      William Karabelas,
    Stephen     Rose,     Michael    Shipman-Meyer,          and       Elizabeth    LaDuca.
    Exactly what        the officers were told about               their assignment is
    unclear.     All the officers understood that they were acting on a
    civil matter,       dealing with a mentally disturbed individual,                    and
    not there to make an arrest.          The evidence suggests that neither
    the DBH employees nor the officers were aware that Mr. Chambers'
    mental health episode was drug-related.                Deposition of Linda Miller
    ("Miller Dep.")       at 19:1-4    [Dkt.   No.    61-10].          However,    prior to
    heading to     the Chambers'       residence,      some of         the officers were
    apparently informed that Mr. Chambers was a butcher by trade, and
    therefore    known     to   carry knives,        and    had    threatened violence
    earlier that day.           Significantly,   Officer Shipman-Meyer was not
    made aware of either of these facts.                   See Deposition of Officer
    Shipman-Meyer ("Shipman-Meyer Dep.") at 71:19-73:2                      [Dkt. No.    61-
    12]; Defs.' Analysis of Material Facts             at~        5.
    These six people then set out for the Chambers'                          apartment.
    Upon arriving they ascended the staircase that led to the landing
    outside the apartment unit.           The DBH employees and MPD officers
    stood at various points outside - on the stairs above the landing,
    on the landing itself, and on the stairs below the ·1anding - and
    -8-
    called for Mr. Chambers to come outside.                These six are the only
    living eyewitnesses to what took place on the landing.
    When    Mr.    Chambers   presented    himself    at    the   door   of    the
    apartment he was shirtless, sweaty, and appeared highly agitated.
    He quickly became verbally combative with the officers.                          As a
    result,      the Officers indicated that they wanted to put him in
    handcuffs before transporting him for treatment.                     Deposition of
    Valentina Chambers ("Chambers Dep.") at 31:10-32:2                   [Dkt. No. 61-
    5] .   All of this was consistent with what the Officers already
    believed - that they were dealing with an agitated, mentally-ill
    individual who was in need of assistance.           Up to this point, there
    was no reason for them to use force against Mr. Chambers, nor did
    they do so.
    The    scene    then   quickly   changed.   Without      provocation       Mr.
    Chambers      attacked    the    officers.     First,     he    punched     Officer
    Karabelas, causing him to fall backwards and hit his head on the
    wall behind him.         Next he punched Officer Rose several times in
    the head.      Finally, he punched Officer Shipman-Meyer in the face,
    causing a fracture to his left orbital bone.
    It is uncontroverted that,         at this point, Mr.          Chambers had
    assaulted two of the officers, likely in violation of D.C. Code                     §
    22-405(b), a misdemeanor, and had assaulted Officer                  Shipman~Meyer
    and likely caused him "significant bodily injury" in violation of
    -9-
    D.C. Code§ 22-405(c),        a felony.   1   At that moment,         the officers
    had probable cause to arrest Mr. Chambers for a crime and, given
    the violent nature of the crime, to use force to seize him.
    They did so,   though precisely what occurred is obscured by
    the haze of battle and inconsistent testimony.             Officers Karabelas,
    Rose,    and   Shipman-Meyer   attempted      to    restrain   and    subdue   Mr.
    Chambers, while Officer LaDuca deployed her pepper spray on Mr.
    Chambers.      Three of the officers,        Karabelas,    Rose,     and Shipman-
    Meyer, all grabbed hold of Mr. Chambers and tried to restrain him.
    Officer Karabelas testified to grabbing hold of Mr. Chambers' right
    arm,    while both Officers Rose and Shipman-Meyer claim to have
    grabbed hold of his left arm.            While holding on to one of Mr.
    Chambers' arms, Officer Shipman-Meyer punched Mr. Chambers in the
    face    multiple   times   with no success         of   calming him.      Officer
    LaDucca, who had been standing further from Mr. Chambers when the
    altercation began and had not been attacked, approached and sprayed
    Mr. Chambers in the face with pepper spray.

    After    she    sprayed Mr.     Chambers      with pepper     spray,   it   is
    undisputed that the struggle between the officers and Mr. Chambers
    then moved from the landing into the apartment.                   Additionally, it
    is undisputed that this transition took only a matter of seconds
    from    the     time    that   Mr.   Chambers      first   attacked   the   officers.
    Defs.' MSJ at 9 (quoting the various officers' depositions). There
    is, however, a significant dispute as to how the officers and Mr.
    Chambers arrived in the apartment.
    According to the account presented by Defendants, they were
    unable to control Mr. Chambers, who used his superior strength to
    drag Officers Rose and Shipman-Meyer - both of whom had grabbed on
    to some part of his body - backwards into the apartment.                       Defs.'
    Analysis of Material Facts at           ~    16 (Mr. Chambers "overpowered" the
    two officers and "dragged them backwards ... against their will");
    Defs.' MSJ at 8.          Yet, that account does not comport with much of
    the evidence in the record.
    First for example, Officer Karabelas, who had a hold of Mr.
    Chamber's right arm, makes no appearance in the Defendants' story.
    See Deposition of Officer Karabelas                 ("Karabelas Dep.") at 41:11-
    52:20    [Dkt.    No.    61-8]   (making clear that he had a hold on Mr.
    Chambers' right arm from the time they were on the landing until
    after they entered the apartment).                    Perhaps that was because,
    unlike the other officers, he did not testify that Mr.                       Chambers
    -11-
    dragged them backward, but simply that they all "fell" together.
    
    Id. at 49:1-8;
         see also "Miller Dep." at 26:9-28:11                  ("they all
    fell in") .
    Second,     the testimony of Mr.        Yingling directly contradicts
    the Defendants' account.            He testified that the officers were able
    to successfully restrain Mr.            Chambers'      arms and knock him "off
    balance," sending him backwards into the apartment and down to the
    ground:       Deposition of Gary Yingling          ("Yingling Dep.")         at 25:2-
    26:13    [Dkt. No. 61-13].        That testimony is partially confirmed by
    the depositions of Officers Karabelas and Rose,                       in which they
    describe having          "locked-up" Mr.     Chambers'    right and left arms,
    respectively.        Karabelas Dep. at 41:11-42:22, 48:5-13, 52:16-20;
    Deposition of Officer Rose ("Rose Dep.") at 22:7-11, 23:10-14 [Dkt.
    No. 61-11].
    The   significance     of     this   dispute     cannot      be   overstated.
    Central to the Defendants'            narrative is the contention that Mr.
    Chambers      was   so   strong   and   so   violent     that   he    was    virtually
    uncontrollable throughout the encounter.                Accordingly, Defendants
    assert that each of the progressively forceful measures deployed
    by the officers up to this point - punches, pepper spray, arm holds
    - failed to subdue Mr. Chambers.                Defs.' MSJ at 16-17.           Despite
    these efforts,        they claim he was able to use his "super-human 11
    -12-
    strength to        "drag    [the officers]      backwards   into his   apartment
    against their will."           
    Id. at 16.
    However, when viewed in its entirety, there is contradictory
    record evidence.           The record plausibly establishes that after the
    surprise of Mr. Chambers' attack had worn off, the officers were
    immediately able to gain a tactical advantage over him through a
    combination of their superior numbers and their own use of force
    -   punches and pepper spray.            It suggests that rather than Mr.
    Chambers dragging them backwards, the officers knocked him back;
    in other words, rather than their use of force being ineffective,
    it was a success.
    The    fight     then    spilled   into    the   apartment.      Valentina
    Chambers,    Mr.     Chambers'    sister,    and two other individuals were
    already inside the apartment, and came into the living room to see
    the commotion that was taking place.
    Once   inside the apartment the struggle continued,                though,
    again,   exactly what transpired is unclear. 2               Two things appear
    2    From   this   point   forward,   the  record   contains   six
    eyewitnesses: the four officers, Mr. Yingling, and Ms. Chambers.
    There is no testimony in the record from the other two individuals
    who were inside the apartment.
    All four of the officers were engaged in a struggle with Mr.
    Chambers, and their respective stories reflect the fact that their
    participation limited their ability to testify clearly or
    conclusively about what occurred.   However, neither Mr. Yingling
    nor Ms. Chambers were participants in the struggle and were able
    -13-
    consistent from the testimony of all individuals.                    First,    from
    this point forward,        there is no evidence that Mr.            Chambers ever
    attempted     to   kick. or   strike    any of    the    officers    again.      See
    Yingling Dep. at 26:6-9; Rose Dep. at 25:2-26:4; Chambers Dep. at
    42:19, 44:12-15      (describing Mr. Chambers as physically unable to
    fight back or move).        This contradicts Defendants' suggestion that
    Chambers was violent throughout the encounter.                  Defs.' MSJ at 10.
    Second,     upon   entering     the   apartment    the    officers     almost
    immediately brought Mr. Chambers down to his knees. Chambers Dep.
    20:15 ("[The officers] wrestled him to the ground."); 
    Id. at 42:9;
    Yingling Dep. at 25:22-27:19. That the officers were able to get
    Mr.    Chambers down on the ground so quickly further undermines
    Defendants'      assertion that they found it impossible to control
    him.    See also Karabelas Dep. at 54:4-6 ("[Mr. Chambers] began to
    weaken" once they entered the apartment) .
    According to Defendants, at the point that Mr. Chambers was
    knocked to the ground but before he was placed in a chokehold,
    they became "separated" and lost sight of one another, with the
    mass of Mr. Chambers blocking the view of one of the Officers and
    any means of escape.          Defs.' Reply at 7; Defs.' MSJ at 9.                But
    to see the entirety of what transpired next. Yingling Dep. 32:13-
    17 (stating he head a "clear, unimpeded view"); Chambers Dep. 21:5-
    22:12 (stating she was three to five steps away from the struggle).
    -14-
    Mr.   Chambers    was   brought    down    almost   instantaneously   after
    entering the apartment, and it is not clear how he could block any
    of the officer's vision while on the ground.             Furthermore,   the
    room was quite small,      so it is unclear how the officers could
    become "separated" or "fragmented" as they were no more than a few
    feet from one another.      See Defs.' Reply at 7; Defs.' MSJ at 9;
    Karabelas Dep. at 50:21-22        (describing the living room as "not a
    big room") .
    From this kneeling position the officers were able to tackle
    Mr. Chambers to a prone position on the ground.            By the time Mr.
    Chambers was     in this prone position,       Officer Shipman-Meyer had
    placed him in a chokehold.        It is difficult to determine from the
    various participants' testimony how long he held Mr. Chambers in
    the chokehold, but it was likely no less than 20 or 30 seconds and
    may have been minutes.3
    3    The officers' testimony makes clear that the enti~e encounter
    was incredibly short, and took as little as one minute and at most
    "a couple minutes."    See Shipman-Meyer Dep. at 107: 15-20.   The
    portion of the encounter that took place on the landing outside
    the apartment lasted no more than 20 seconds. See Karabelas Dep.
    at 46:15-47:15. While no witness provided an estimate of how long
    it took to bring Mr. Chambers to the ground, the fairest reading
    of the record is that it was also quite short.   Even if the Court
    were to assume that it took ten or even twenty seconds to bring
    him to the ground, and based on the testimony even twenty seconds
    seems far-fetched, that would suggest that Mr. Chambers was placed
    in a chokehold no later than 30-40 seconds after the encounter
    began.
    -15-
    According to Defendants,   Mr.    Chambers continued to resist
    after Officer Shipman-Meyer had placed him in the chokehold, and
    this necessitated the continued use of the chokehold until he was
    incapacitated and non-responsive. 4    Defs.' MSJ at 12.    Officer
    Shipman-Meyer testified that he was in a vulnerable position -
    face down on the floor and unable to see what was transpiring -
    Thus, even crediting the off ice rs' testimony implies that
    Officer Shipman-Meyer held Mr. Chambers in a chokehold for at least
    20-30 seconds, assuming the encounter lasted no more than a minute.
    To the extent the encounter lasted two minutes, then Officer
    Shipman-Meyer would have held him in a chokehold for up to 90
    seconds, although no one directly testified that the chokehold
    lasted that long.   And if Officer Shipman-Meyer used "a couple
    minutes" in the colloquial sense to mean "a few minutes," it may
    have been even longer.
    Moreover, Plaintiff has introduced evidence of the extent and
    nature of Mr. Chambers' injuries which suggest that he was subject
    to a tracheal choke hold. See Expert Report of Dr. Jonathan Arden
    ("Arden Report")   [Dkt. No. 61-1]; Expert Report of Fernando
    Yamasaki, Exh. 9 to Pl. 's MSJ at 4 [Dkt. No. 56-1] ("Yamasaki
    Report") (stating that Mr. Chambers neck was so large, Officer
    Shipman-Meyer would have been unable to place him in a pure carotid
    choke) . Plaintiff has also introduced evidence indicating that a
    tracheal chokehold takes up to three minutes to render a subject
    unconscious, as may have occurred with Mr. Chambers.     See Marine
    Corps Close Combat Manual, Chapter 6 Choke Holds, Exh. 15 to Pl.'s
    Opp'n [Dkt. No. 63-1] ("Marine Corps Close Combat Manual"). This
    further supports the inference that Mr. Chambers was held in a
    chokehold for a significant amount of time.
    4    According to Officer Shipman-Meyer, Mr. Chambers was lying on
    his left side and Officer Shipman-Meyer's right arm was around Mr.
    Chambers' neck in a carotid hold. Officer Shipman-Meyer testified
    that he was face down on the floor, unable to see Mr. Chambers or
    the other officers. He further testified that he felt vulnerable
    in this position, as Mr. Chambers was continuing to resist and was
    attempting to roll on top of him. At 78:14-88:4.

    and     that    Mr.    Chambers      was    attempting       to    roll   on top of     him.
    Shipman-Meyer Dep. at 78:14-88:4.
    In contrast, testimony from Ms. Chambers, Mr. Yingling, and
    several of the other officers suggests that the officers already
    had the upper hand and that Mr. Chambers was effectively subdued
    by this        time.        Chambers Dep.      at    42:16-45:5         (stating that Mr.
    Chambers       "couldn't fight back"            because he was being held in a
    chokehold by one officer, with multiple other officers on top of
    him).     Similarly, Officer LaDuca testified that Mr. Chambers was
    face down on his stomach with Officer Shipman-Meyer on top of Mr.
    Chambers' back, and that Mr. Chambers was completely surrounded by
    the other officers.             Deposition of Officer LaDuca Dep.                  ("LaDuca
    Dep")    at 41:22       -    45:22,    51:3-7       [Dkt.    No.    61-9].    Indeed,    she
    describes an extended sequence in which she attempted to strike
    Mr.   Chambers with her ASP baton while he was on the ground and
    then repeatedly tried to pry his arms out from under him, using
    the baton as a lever.             LaDucca Dep. at 41:8-43:2.
    Officer Karabelas,            in addition to Officer LaDuca,               also saw
    Officer Shipman-Meyer on top of Mr. Chambers and testified that he
    had hold of one of Mr. Chambers arms.                       Karabelas Dep. at 57:3-8,
    58:4-5.        Similarly,      Mr.    Yingling testified that as soon as Mr.
    Chambers       was     taken    to    the    ground     he        saw   multiple   officers
    restraining both of his arms.                 Yingling Dep. at 27:22-28:1.
    -17-
    None of the other officers - nor Mr. Yingling - saw Officer
    Shipman-Meyer place and maintain a chokehold on Mr. Chambers.             This
    despite the fact that they were mere feet from Officer Shipman-
    Meyer when he was using the chokehold and that the use of the
    chokehold may well have lasted at least 30 seconds - which is at
    least as long as all the prior events in the encounter - if not
    several minutes longer.
    For example, despite being directly above the two and with a
    clear vantage point,       Officer LaDuca claims       to have never seen
    Officer Shipman-Meyer place his arms around Mr.             Chambers'    neck.
    LaDuca Dep. at 50:21-51:1-2.          Similarly, Officer Rose claims not
    to have seen Officer Shipman-Meyer with an arm around Mr. Chamber's
    neck, despite being mere inches or feet away from him.               Rose Dep.
    at 29:19-21.      Officer Karabelas did see Officer Shipman-Meyer with
    his arms around Mr. Chambers' neck or shoulder area, but was unable
    to see whether or not Officer Shipman-Meyer had placed him in a
    chokehold.      
    Id. at 56:21-59:2.
       Similarly, Mr. Yingling, who claims
    to   have   a   "clear,   unimpeded    view"   throughout   the   encounter,
    Yingling Dep. at 32:13-17,       nonetheless states that he never saw
    Officer Shipman-Meyer use a chokehold.           
    Id. at 31:9-12.
         All of
    this testimony is implicitly contradicted by that of Ms. Chambers,
    who was present for the same events, but had no trouble seeing her
    brother being choked.       Chambers Dep. at 42:21-45:5.

    ..   '
    Officer     Shipman-Meyer   maintained      the    hold     for    some
    indeterminate amount of time,       eventually releasing Mr.       Chambers
    when he determined that Mr. Chambers had stopped moving.            At this
    time the other officers who had been attempting to handcuff Mr.
    Chambers were finally able to do so.          Very      shortly        after
    placing him in handcuffs,    the officers noticed Mr. Chambers was
    non-responsive and in apparent medical distress.               The officers
    agree that they rolled him into an upright position on the floor
    and checked his pulse and breathing, but none provided emergency
    first-aid   assistance.    One   of   the   officers,   possibly Officer
    LaDuca,   called for an ambulance.       Other officers arrived on the
    scene, and the four officers who were involved in the melee left
    the apartment.     Some amount of     time passed before an ambulance
    arrived and took Mr. Chambers for treatment, but he died en route
    to the hospital.
    None of   the following material questions are conclusively
    resolved by the record.      Did Mr. Chambers possess such "super-
    human" strength, that it was impossible to control him, or did the
    officers immediately gain an advantage in their battle with him
    after the surprise of his attack had faded?          Did Officer Shipman-
    Meyer use the chokehold as a last-ditch effort to gain control of
    Mr. Chambers or had he already been subdued at that point?               Did
    Officer Shipman-Meyer maintain the chokehold for only the bare
    -19-
    :   ·•
    minimum of time necessary to handcuff Mr.                   Chambers,   or did he
    maintain it for a significant period of time after Mr. Chambers
    had been subdued?
    Having reviewed in great detail the testimony presented by
    the various witnesses,       the Court has no trouble concluding that
    there are material facts in dispute.
    II.    STANDARD OF REVIEW
    Summary judgment may be granted only if the pleadings,                    the
    discovery materials, and affidavits on file show that there is no
    genuine issue as to any material fact and that the moving party is
    entitled to judgment as a matter of law. See Arrington v. United
    States, 
    473 F.3d 329
    , 333 (D.C. Cir. 2006); Fed. R. Civ. P. 56(c).
    "A dispute over a material fact is 'genuine' if 'the evidence is
    such    that   a   reasonable    jury    could   return      a   verdict   for   the
    nonmoving party.'"        
    Arrington, 473 F.3d at 333
                (quoting Anderson
    v.    Liberty Lobby,     Inc.,   
    477 U.S. 242
    ,   248    (1986)).   A fact    is
    "material" if it might affect the outcome of the case under the
    substantive governing law. 
    Id. The burden
    is on the moving party to demonstrate the absence
    of any genuine issues of material fact. Celotex Corp. v. Catrett,
    
    477 U.S. 317
    ,    323   (1986). When a moving party successfully does
    so, the nonmoving party must show the existence of a genuine issue
    of material fact by providing "specific facts showing that there
    -20-
    is     a    genuine    issue    for   trial,"      and     "may   not      rest   on   mere
    allegations or denials" to prevail.                 Burke v. Gould, 
    286 F.3d 513
    ,
    517 (D.C. Cir. 2002)           (quoting 
    Anderson, 477 U.S. at 248
    (internal
    quotation marks omitted) . The moving party is entitled to summary
    judgment        when   the     nonmoving    party        fails    to     offer    evidence
    sufficient to establish an essential element of a claim on which
    it will bear the burden of proof at trial. 
    Celotex, 477 U.S. at 322
    .
    In reviewing the evidence on a motion for summary judgment,
    the court views the evidence in the light most favorable to the
    nonmoving party and draws all inferences in her favor. Johnson v.
    Perez,        
    823 F.3d 701
    ,   705    (D.C.    Cir.     2016).            "Credibility
    determinations,        the weighing of the evidence, and the drawing of
    legitimate inferences from the facts are jury functions, not those
    of a judge at summary judgment."                   Barnett v.     PA Consulting Grp.
    Inc., 
    715 F.3d 354
    , 358 (D.C. Cir. 2013)                  (internal quotation marks
    and citation omitted). Accordingly, the Court's role is "not [to]
    determine the truth of the matter,                  but instead         [to]   decide only
    whether there is a genuine issue for trial."                      
    Id. III. ANALYSIS
    Plaintiff brings two distinct sets of claims in this action.
    First, he brings claims based on a federal statute,                            42 U.S.C.   §
    1983, against all four officers alleging that they violated his
    -21-
    father's constitutional rights.       Second,    he brings a number of
    claims based on the laws of the District of Columbia against the
    officers   and   the   District   itself.       The   Court   begins   with
    Plaintiff's federal claims before turning to his claims based on
    the laws of the District.
    A. Federal Section 1983 Claims against the Four Officers
    Count Three of Plaintiff's Complaint alleges that the four
    officers violated his father's rights under the Fourth Amendment
    of the United States Constitution to be free from excessive force.
    First,   Plaintiff argues that Officer Shipman-Meyer violated his
    father's rights by using a chokehold on him.           Second,   Plaintiff
    argues that the other three officers violated his father's rights
    by failing to stop Officer Shipman-Meyer. The Court will deal with
    each claim in turn.
    1. Neither Party Is Entitled to Summary Judgment on
    the Claims against Officer Shipman-Meyer
    Plaintiff claims that Officer Shipman-Meyer used excessive
    force against Mr. Chambers and thereby violated 42 U.S.C.          §   1983,
    and has moved for summary judgment.         Defendants have also moved
    for summary judgment arguing that the claim is barred under the
    doctrine of qualified immunity.      The Court begins with the issue
    of qualified immunity.
    -22-
    a. Officer Shipman-Meyer Is Not Entitled to
    Qualified Immunity for his Use of a Chokehold
    i.   Qualified Immunity Standard
    "In order to protect officers from undue interference with
    their duties and from potentially disabling threats of liability,
    qualified immunity shields federal officials from damages suits
    for    actions     taken     while     carrying      out   their   official      duties."
    Fenwick v. Pudimott, 
    778 F.3d 133
    , 136-37 (D. C. Cir. 2015) .                            "To
    defeat a defense of qualified immunity, a plaintiff must show not
    only that an official 'violated a constitutional right' but also
    that     'the   right      was   clearly established'         at   the    time      of    the
    violation.         
    Id. at 137
         (quoting Saucier v.      Katz,     
    533 U.S. 194
    ,
    200-01    (2001));        see also Plumhoff v.         Rickard,    134 S.     Ct.    2012,
    2023     (2014).         Both prongs      of   the   qualified     immunity analysis
    present pure questions of law.                 See Scott v. Harris, 
    550 U.S. 372
    ,
    381 n. 8 (2007).
    In deciding a motion for summary judgment on the basis of
    qualified immunity, the plaintiff is the non-moving party, and the
    Court resolves all issues of material fact in her favor.                            
    Scott, 550 U.S. at 378-79
    .              In cases involving deadly force,             the Court
    does not simply accept the account of the officers, but instead,
    carefully examines all the evidence to determine whether a rational
    -23-
    jury could conclude that the officer acted unreasonably.                               
    Flythe, 791 F.3d at 19
    .
    ii.       Prong 1: Officer Shipman-Meyer Violated
    the Constitution
    Defendants argue that Officer Shipman-Meyer is entitled to
    qualified immunity because his use of a chokehold on Mr. Chambers
    was reasonable and therefore did not violate the Fourth Amendment.
    "Apprehension          of     a        suspect     through   deadly      force,       i.e.,
    killing    him,    qualifies           as    a   Fourth Amendment        seizure,      and    is
    therefore unlawful unless objectively reasonable in light of the
    facts and circumstances confronting                       [the officer] . "        Flythe v.
    District of 
    Columbia, 791 F.3d at 18
    (citing Tennessee v. Garner,
    
    471 U.S. 1

    490 U.S. 386
    , 397 (1989}
    (internal       quotation          marks          omitted)) .        "To         assess      the
    reasonableness of a seizure,                     [the Court] must balance the nature
    and quality of the intrusion on the individual's Fourth Amendment
    interests against the            importance of            the governmental          interests
    alleged    to     justify    the        intrusion."          Johnson     v.      District     of
    Columbia, 
    528 F.3d 969
    , 974 (D.C. Cir. 2008).
    The    Court     "give[s]              careful     attention   to     the     facts     and
    circumstances of the particular case,                      including the severity of
    the crime at issue, whether the suspect poses an immediate threat
    to the safety of the officer or others, and whether he is actively
    -24-
    resisting      arrest     or   attempting        to   evade    arrest    by   flight."
    
    Johnson, 528 F.3d at 974
    .      The Court "analyze[s]              this question
    from the perspective "of a reasonable officer on the scene, rather
    than with the 20/20 vision of hindsight."                 
    Plumhoff, 134 S. Ct. at 2020
    .
    In assessing an officer's use of deadly force, the test does
    not differ from a claim involving less-than-deadly force; the sole
    inquiry is whether          the   force    used was      objectively reasonable.
    
    Scott, 550 U.S. at 381-83
    .           However, the "nature and quality" of
    the intrusion on the individual's Fourth Amendment interest is at
    a maximum in a deadly force case because she has been deprived of
    her greatest liberty interest, her life.                Accordingly, the primary
    focus is on whether the government's interests can justify that
    intrusion.      Ordinarily, the use of deadly force is reasonable where
    an individual "poses an actual and imminent threat to the lives of
    the officers involved" or other individuals.                   See 
    Flythe, 791 F.3d at 18
    .
    In this case,     the Court is called upon to determine whether
    Officer Shipman-Meyer's use of a                 chokehold on Mr.        Chambers was
    reasonable.          In order to make this assessment,              the Court begins
    with a discussion of the chqkehold procedure.
    The   term    "chokehold"   is    imprecise,      as   it   encompasses    two
    seemingly distinct control procedures.                 One of these procedures is
    -25-
    the "carotid hold" in which "an officer positioned behind a subject
    places one arm around the subject's neck and holds the wrist of
    that arm with his other hand.           The officer,    by using his lower
    forearm and bicep muscle,       applies pressure concentrating on the
    carotid arteries located on the sides of the subject's neck. The
    carotid hold is capable of rendering the subject unconscious by
    diminishing the flow of oxygenated blood to the brain."            Lyons v.
    Los Angeles,   461 US.   95,   97 n.1    (1983).     The carotid hold, when
    properly applied, renders the subject unconscious in a matter of
    seconds.   Marine Corps Close Combat Manual at 1.
    The term "chokehold" may also refer to "tracheal holds," also
    known as "bar arm" holds.       Yamasaki Report at 1; see also        
    ~yons, 461 U.S. at 97-98
    .    In this procedure an officer positioned behind
    the subject uses his arm or arms in a manner similar to the "carotid
    hold," but applies pressure to the subject's trachea, reducing the
    flow of oxygen to the subject's lungs.             The tracheal hold is also
    able to render a     subject unconscious,          but ordinarily takes far
    longer than the carotid hold to do so.              The record in this case
    suggests that a tracheal hold takes anywhere from 2-3 minutes to
    render a subject unconscious, even when correctly applied.            Marine
    Corps Close Combat Manual at 1.
    The two procedures are often discussed as though they are
    wholly distinct.     In practice it is difficult to apply one without
    -26-
    also applying the other.         Yamasaki Report at 1.           For example, an
    officer may seek to place an individual in a                    carotid hold but
    inadvertently apply pressure to the subject's trachea, cutting off
    air flow to the subject's lungs as well as his brain.                   
    Id. In that
    case, the officer has effectively placed the subject in both
    a carotid and tracheal hold.           It is especially difficult to apply
    one type of hold where the officer and subject are engaged in a
    physical struggle because the movement of both officer and subject
    prevent the officer from precisely directing where she applies
    pressure to the subject's neck.           
    Id. It is
       self-evident   that     both   forms     of    chokeholds    are
    potentially lethal.      To live, a human needs oxygenated blood to be
    delivered to the brain and needs a sufficient amount of oxygen to
    be delivered to the lungs.        Chokeholds arrest these processes, and
    if held for a       sufficient amount of time necessarily carry the
    potential for death.       
    Lyons, 461 U.S. at 117
    n.             7 (Marshall, J.
    dissenting) . s
    For   these    reasons,    the    application   of    any    chokehold    is
    properly considered the application of deadly force.                See Coley v.
    5    The lengthy duration of a chokehold is not the only mechanism
    that may cause death.   
    Lyons, 461 U.S. at 117
    n. 7 (Marshall, J.
    dissenting) .  Even chokeholds of a short duration can damage
    structures in the neck, thereby leading to asphyxiation.        In
    addition, carotid holds may trigger processes in the central
    nervous system that lead to cardiac arrest.   
    Id. -27- Lucas
          County,      
    799 F.3d 530
    ,    541    (6th   Cir.    2015)    (describing a·
    chokehold as "deadly physical force");                        Nava v. Dublin,       
    121 F.3d 453
    ,       458   (9th Cir.         1997)     (letting stand district court finding
    that carotid hold constitutes "deadly force"), overruled on other
    grounds in Hodgers-Durgin v. De La Vina, 
    199 F.3d 1037
    , 1040 n.1
    (9th Cir.        1999).            Indeed,   the District of Columbia itself has
    statutorily established that the application of a chokehold by a
    law enforcement officer "constitutes the use of lethal force."                            DC
    St.    §    5-125. 01.
    The nature of a chokehold informs the excessive force analysis
    in subtle, but significant ways.                  While some applications of force,
    such as a gunshot, are instantaneous and discrete, the application
    of a chokehold is not; it is, instead, continuous.                            When an officer
    shoots an individual, there is a single decision point, whether or
    not to pull the trigger.                Thus, in determining whether an officer's
    shooting of an individual was reasonable,                            the analysis properly
    focuses on what transpired before she pulled the trigger.
    In contrast,        a    chokehold is applied to a            subject and then
    held for some indeterminate period of time.                             Once applied,     the
    officer retains the ability to release the hold.                          Consequently, in
    the context of a chokehold case, the analysis of whether an officer
    acted reasonably focuses not only on the decision to apply the
    hold in the first              instance but also on the officer's continued
    -28-
    application      of   the   hold.      An    officer     may   act   reasonably       in
    initially placing a subject in a chokehold - because the subject
    poses a threat - but act unreasonably in her continued application
    of the hold because the threat has passed.                 See 
    Flythe, 791 F.3d at 22
    ("Justification for deadly force exists only for the life of
    the threat.").
    With these principals in mind, the Court analyzes the facts,
    known to Officer Shipman-Meyer from the time he first placed Mr.
    Chambers in a chokehold until the time he released him, in order
    to determine whether the Officer's conduct was reasonable.                      Officer
    Shipman-Meyer knew that Mr.           Chambers was an agitated, mentally-
    ill man, who had threatened or menaced the DBH employees, but he
    had no reason to believe that Mr. Chambers had committed a crime
    or was armed.
    Very   soon   after   the    officers'      arrival     at   the       Chambers'
    residence,     Mr.    Chambers      became    violent,    launching        a    surprise
    attack against Officer Shipman-Meyer and his colleagues.                            They
    responded with force, punching and pepper spraying him, and quickly
    knocked him to his knees and then to the ground.                       Once on the
    ground, two of the officers effectively restrained Mr. Chambers'
    arms,    while Officer Shipman-Meyer straddled his back.                        All the
    while Officer LaDuca stood at                the   ready to assist         her fellow
    -29-
    officers.      At this point, the officers had effectively subdued Mr.
    Chambers.
    At some point during all this chaos - but certainly no later
    than when Officer Shipman-Meyer was on top of Mr. Chambers' back
    -   Officer Shipman-Meyer put him in a chokehold.                      Yet,   once Mr.
    Chambers    was    subdued       and     despite        the    fact    that     he   was
    outnumbered, did not possess a weapon, had never attempted to grab
    a weapon, and that his crime was assaulting the officers with his
    bare   hands       Officer    Shipman-Meyer           continued       choking    him
    potentially for 90 seconds,          if not more - until he became non-
    responsive.       The Court concludes that             it was unreasonable for
    Officer Shipman-Meyer to continue choking Mr. Chambers after the
    officers had subdued him.
    The use of force on a suspect who has already been subdued is
    plainly excessive.        See e.g.     Baker v. City of Hamilton, 
    471 F.3d 601
    , 607 (6th Cir. 2006)       ("We have held repeatedly that the use of
    force after a      suspect has been incapacitated or neutralized is
    excessive as a matter of law.")          i       Abbott v.    Sangamon County,         
    705 F.3d 706
    , 732 (7th Cir. 2013)          ("police officers cannot continue to
    use force once a suspect is subdued")                 "This prohibition against
    significant       force      against         a      subdued      suspect        applies
    notwithstanding      a     suspect's     previous        behavior             including
    resisting     arrest,     threatening    officer        safety,       or   potentially
    -30-
    carrying a weapon. "          Miller v. Gonzalez,          
    761 F.3d 822
    ,       829   (7th
    Cir. 2014).
    Accordingly, courts have consistently held that officers may
    not    continue      to    use    chokeholds        and   other    similarly     lethal
    restraints on a suspect after he has been subdued.                        See Drummond
    v. City of Anaheim, 
    343 F.3d 1052
    (9th Cir. 2003)                   (it was excessive
    force for two officers to sit on subject - causing him "positional
    asphyxia" - after he had been subdued); Weigel v. Broad, 
    544 F.3d 1143
        (10th    Cir.    2008)   (sitting     on    subject      after   he   has   been
    subdued, causing asphyxiation, constitutes excessive force), cert
    denied, 
    556 U.S. 1236
    (2009); Booker v. Gomez, 
    745 F.3d 405
    (10th
    Cir.   2014)     (continued use of chokehold on subject after he had
    been subdued constituted excessive force, even though he had tried
    to punch the officer) .
    The reason for such a rule is obvious: once an individual has
    been effectively subdued, she no longer poses a significant threat
    to the officers or others, and therefore the need to use force has
    ended.
    In Drummond, a man called the police to assist his neighbor,
    who was experiencing a mental health 
    episode. 343 F.3d at 1054
    .
    Three officers knocked the neighbor to the ground and handcuffed
    him.     
    Id. Despite the
    fact that he was subdued and face down on
    the ground, two officers placed their weight on his neck and torso
    -31-
    to further restrain him.              
    Id. at 1054-55.
          The combined weight of
    the officers caused Drummond to experience positional asphyxia and
    put him into a permanent vegetative state.                     
    Id. at 1055,
        1057.
    The court held that once Drummond was on the ground and subdued he
    no longer posed a threat to the officers and others.                     
    Id. at 1057-
    58.     Consequently,       the officers'       decision to restrain him in a
    manner that was         likely to asphyxiate him was unreasonable and
    excessive.      
    Id. at 1058-60.
    In Weigel,      the police and Weigel were             involved in a        car
    accident on the 
    highway. 544 F.3d at 1147
    .        After the accident,
    Weigel began behaving erratically, running into traffic.                        
    Id. at 1148.
        The officers tackled Weigel and tried to restrain him, but
    he resisted their efforts.              
    Id. Eventually, they
    handcuffed him
    and tied up his legs but he continued to struggle, so one of the
    officers sat on his torso while a bystander sat on his legs for
    several minutes.         
    Id. Weigel was
    asphyxiated as a result of the
    pressure on his chest and died.                
    Id. The Court
      held     that    the    off ice rs   should have    known    that
    restraining Weigel in this manner was potentially lethal.                       
    Id. at 1153.
        Given that they had already subdued him,                   the court held
    that their use of a potentially-lethal restraint was unreasonable
    and excessive.        
    Id. -32- In
    this case, Mr. Chambers was significantly outnumbered by
    the police.      Three officers had effectively pinned Mr. Chambers to
    the ground and gained control of his arms, while a fourth officer
    stood at the ready to assist them.        Under such circumstances, the
    officers had subdued Mr. Chambers, and he did not "pose[] an actual
    and imminent threat to the lives of the officers involved" or other
    individuals. 6     See 
    Flythe, 791 F.3d at 18
    .     Once he was subdued,
    continued use      of   the   chokehold was   unnecessary     and     therefore
    unreasonable and excessive.
    Officer Shipman-Meyer was        aware   of   all   of   these    relevant
    facts,   and it should have been obvious to him that the extended
    use of a chokehold was potentially lethal. 7             Consequently,      his
    6    The fact that Mr. Chambers was not handcuffed at this stage
    does not mean he was not subdued. See Malory v. Whiting, 489 Fed.
    Appx. 78, 86 (6th Cir. 2012) (unpublished) (holding that although
    Plaintiff was not handcuffed, he was nonetheless subdued, and
    therefore, forced use was unreasonable); Laury v. Rodriguez, 659
    Fed. Appx. 837, 844 (6th Cir. 2016) (unpublished)     (describing
    Malory as rejecting argument that the right to be free from
    excessive force once subdued was not clearly established because
    the plaintiff was not handcuffed) .
    7    The District's statutes establish that the use of a chokehold
    constitutes "lethal force", DC St. § 5-125.01.     Given the common
    law presumption that "every person [knows] the law," Cheek v. US,
    
    498 U.S. 192
    , 199 (1991), it is appropriate to presume a reasonable
    MPD officer was aware of that fact.    See Kleinberg v. Clements,
    
    2012 WL 1019290
    , *9 (D.N.J. March 23, 2012) ("police officers are
    presumed to know the law"); Brewer v. Hayman, 
    2009 WL 2139429
    , *8
    (D.N.J. July 10, 2009).
    -33-
    decision to maintain a chokehold on Mr. Chambers after he had been
    subdued was objectively unreasonable.a
    Moreover,   the fact that Mr. Chambers resisted the officers'
    attempts to handcuff him and was not handcuffed until after the
    chokehold was released does not alter the analysis.             A number of
    courts have held that it is unreasonable for an officer to use a
    chokehold in order to make an arrest, simply because the individual
    resists being handcuffed.
    In Thompson v.   Chicago,   the court held that an officer was
    not entitled to qualified immunity where he used a chokehold in
    order to arrest a suspect who had both fled and fought with the
    police.     
    2004 WL 1197436
      (May 28, 2004 N.D. Ill.).     In Thompson,
    two police officers were on patrol and saw Thompson engage in an
    apparent drug purchase.       
    Id. at *1-2.
      Thompson saw the officers
    and fled in his car.       
    Id. The officers
    pursued him,        and several
    other cars joined the chase before Thompson crashed.            
    Id. Thompson emerged
    from the car, and two of the many officers
    on hand attempted to subdue him.       Thompson punched one of the two
    officers, which resulted in a physical struggle.          
    Id. All three
    fell   to   the   ground and Thompson continued to    struggle        as   the
    s    This is sufficient, in and of itself, to defeat Officer
    Shipman-Meyer's arguments on the first prong of the qualified
    immunity analysis.
    -34-
    officers attempted to handcuff him.                    
    Id. One of
    the officers was
    able to climb on Thompson's back and place him in a chokehold,
    which he maintained until                  Thompson was        eventually handcuffed.
    Shortly thereafter, Thompson began to exhibit signs of respiratory
    distress and eventually died.                   
    Id. Despite Thompson's
    potential drug crime, attempt to flee from
    arrest,    violent      assault       of    a    police      officer,      and   subsequent
    attempts to resist being handcuffed and arrested, the court held
    that the officer was not entitled to qualified immunity.                             
    Id. at *5.
      Even under this set of facts, the court held that the use of
    deadly    force,   in      the   form      of    a    chokehold,    was     excessive   and
    unreasonable.        
    Id. Indeed, the
    defendants themselves conceded
    that the use of a           chokehold was unreasonable and violated the
    Fourth Amendment.9         
    Id. Similarly in
    Griffith v.                   Coburn,     the   court    held that    an
    officer lacked qualified immunity where he had been called by
    Arthur Partee' s      mother      -   because he was experiencing a mental
    health issue - and he placed Mr. Partee in a chokehold after Partee
    9 The Defendants denied that any officers had used a chokehold and
    a jury ultimately acquitted the officers on the claim of excessive
    force.   See Thompson v. Chicago, 
    472 F.3d 444
    (7th Cir. 2006).
    However, the jury's decision does not alter or displace the
    district court's conclusion that use of a chokehold constituted
    deadly force and that deadly force was unauthorized under the
    circumstances.

    resisted the officer's attempts to handcuff him.                             
    473 F.3d 650
    ,
    651-53     (6th    Cir.        2007).         The     officers    lacked     authority          to
    involuntarily commit Partee, but - in order to get him treatment
    - decided to arrest him on an outstanding warrant stemming from a
    traffic ticket.          
    Id. Partee refused
    to go with the officers, and
    when they attempted to handcuff him, he resisted their attempts to
    do so.    
    Id. During the
    course of the struggle, one of the officers
    claimed    Partee     attempted          to    grab     his    gun,   and   put    him     in    a
    chokehold, leading to his death.                      
    Id. at 654.
    On this set of facts the court held that a jury could find
    that     the    officer's        use     of    the     chokehold      was   excessive       and
    unreasonable.         
    Id. at 657-58.
           The     court   did   so    even   after
    accepting the officer's contention that Partee had attempted to
    grab his gun.       
    Id. The court
    reasoned that, despite this attempt
    to grab the gun,            Partee never actually posed a                   threat to the
    officers because he was unsuccessful in grabbing the gun.                                   
    Id. The court
    held that, absent such a real threat, the officer lacked
    justification to use deadly force against Partee.                           
    Id. Thompson and
    Griffith both make                        clear that     the   use     of    a
    chokehold       simply     as     a     tool     of    effecting      an    arrest    is    not
    reasonable.       Chokeholds are not justified simply because a suspect
    resists being handcuffed,                or even punches an officer.                 Instead,
    the suspect must have done something that makes him a threat to
    -36-
    the lives of the officers or others.              In this case, when the facts
    are viewed in a          light most favorable to Plaintiffs,                Defendants
    cannot demonstrate that Mr. Chambers posed this level of threat.
    The     Defendants'     counterarguments       are     unpersuasive.         The
    Defendants claim that the following factors,                    when considered in
    their     totality,     justify Officer        Shipman-Meyer's        use   of   deadly
    force:    the     officers were      injured,     exhausted,     and losing their
    battle with Mr. Chambers when Officer Shipman-Meyer placed him in
    a chokehold; addi,tional individuals were present in the apartment,
    instilling further fear in the officers; and Mr. Chambers continued
    to resist throughout the encounter and had been extremely violent
    at its outset.
    As to the first factor - whether the officers were losing
    their battle with Mr. Chambers - that is a question of fact for
    the jury.        As discussed above, even accepting the officers' claim
    that they were injured and exhausted,                  there is evidence in the
    record suggesting that the officers had effectively subdued Mr.
    Chambers despite their physical condition.                     Accordingly,      a jury
    could    reasonably      choose     to    disbelieve    Defendants'        account   and
    conclude        that    continued        application    of     the    chokehold      was
    unreasonable and excessive.
    As to the presence of other indi victuals in the apartment,
    that     fact    is    wholly   unpersuasive.          There    was   no    basis    for
    -37-
    suspecting      that     those   individuals        were      criminals      or
    coconspirators, because the officers were there on a mental health
    call,    not in response to a report of criminal activity.                Thus,
    there was no objective basis to regard them as a threat. 10
    The fact that Mr.   Chambers attacked the officers does not
    change this calculus because - from the officers' vantage point -
    his violence was       the result of   a   mental heal th issue and not
    connected to any underlying criminal activity.             While the presence
    of criminal accomplices may increase the danger perceived by a
    reasonable officer,     the Defendants fail to identify any case in
    which the presence of innocent bystanders validates a heightened
    perception of     danger by an officer.        As    the    officers   had no
    objective basis for perceiving these other individuals as a threat,
    their presence does not justify any additional force beyond that
    which was reasonable had they not also been in the apartment.
    Defendants' argument that use of the chokehold was justified
    by Mr. Chambers' continued resistance also fails.              The evidence,
    viewed in a light most favorable to plaintiff, casts doubt on the
    notion that Defendant was violently resisting when he was placed
    10 Moreover, the actions of these individuals confirmed to the
    officer's that they were not a threat.  For example, the officers
    heard the occupants of the apartment discuss the need to let the
    police do their job and not interfere.   Karabelas Dep. at 66:8-
    12; Yingling Dep. at 29:15-19.
    -38-
    in a    chokehold.       Instead,      the    record suggests       that after the
    initial punches thrown on the landing, Mr. Chambers did not throw
    or land a       single punch,     kick or other blow,            at least in part
    because the officers had successfully subdued him.
    The officers argue that even if he was unable to land another
    blow, Mr. Chambers continued to struggle while he was on the ground
    and    in a    chokehold.       The    only real       description of       what   this
    struggle entailed was given by Officer Shipman-Meyer who described
    Mr.    Chambers as      "flailing"      and   "rolling."      Shipman-Meyer Dep.
    80:14-21,     87:17-88:4.
    Yet,    as Plaintiff's expert points out,             such behavior is a
    virtually      automatic,    subconscious        response     to    being     manually
    asphyxiated.       Yamasaki Report at 3.           That an individual, who is
    literally being choked to death, would flail in response would be
    obvious to any reasonable person, including Officer Shipman-Meyer.
    Accordingly,      the   Court    cannot       credit    Defendants'    attempts         to
    characterize these movements as violent resistance.                        In light of
    the other evidence suggesting that Mr.                  Chambers was effectively
    subdued,      these movements,        whatever they were,        would not justify
    Officer Shipman-Meyer's continued use of the chokehold.
    Ultimately, the heart of the Defendants' argument is that Mr.
    Chambers had violently attacked the officers,                    and therefore,         it
    was    reasonable    for    Officer      Shipman-Meyer      to     place    him    in    a
    -39-
    chokehold until he was handcuffed.             Defendants' argument ignores
    the evidence suggesting that Officer Shipman-Meyer continued to
    choke Mr. Chambers after the officers had effectively subdued him.
    There is a clear "prohibition against significant force against a
    subdued      suspect ... notwithstanding            a      suspect's      previous
    behavior .... "    
    Miller, 761 F.3d at 829
    .             As our Court of Appeals
    has said, "That an individual at one point posed a threat does not
    grant officers an irrevocable license to kill."                
    Flythe, 791 F.3d at 22
    .
    For all     these reasons,      the Court finds        that a     jury could
    reasonably     conclude     that   Officer     Shipman-Meyer's          use    of     a
    chokehold was objectively unreasonable and violated Mr. Chambers'
    rights under the Fourth Amendment.
    iii.   Prong 2: The Right to Be Free from Deadly
    Force    once   Subdued    Was    Clearly
    Established
    Though a reasonable jury could conclude that Officer Shipman-
    Meyer used excessive force in violation of the Fourth Amendment,
    he is still entitled to qualified immunity if the right to be free
    of   such force    was not clearly established at              the     time   of    the
    violation, which was June 8, 2012.
    This prong of the qualified immunity analysis "begin [s]                       by
    establishing      the   appropriate    level   of       generality at     which      to
    analyze the right at issue."          Johnson v. District of Columbia, 528
    -40-
    F.3d 969, 975 (D.C. Cir. 2008).                    It is insufficient to ask whether
    Mr.    Chambers had a right to be free from unreasonable seizure.
    
    Id. Instead, the
    "dispositive inquiry ... is whether it would be
    clear to a reasonable officer that his conduct was unlawful in the
    situation he confronted.              11
    
    Id. In this
    case, the relevant question
    is    whether     a    reasonable          officer would         have    known    that    it    is
    unlawful     to       use     a   potentially           lethal   restraint,        such    as    a
    chokehold,      on     an     individual         who    has   already      been    subdued      by
    multiple officers.
    "To determine whether the officer[]                       'strayed beyond clearly

    ....
    It is clear that as of June 8,             2012,    a reasonable officer
    would have been on notice that she could not choke to death an
    unarmed subject who had already been subdued by fellow officers.
    An officer may use deadly force where a suspect "pose[s] an actual
    and imminent threat to the lives" of the officer or others.                
    Scott, 550 U.S. at 384
    .         Once a suspect is subdued, they no longer pose
    a sufficient threat to justify the use of force.                    See Abbott v.
    Sangamon County, 
    705 F.3d 706
    , 732 (7th Cir. 2013)                  ("it was well-
    established in 2007 that police officers cannot continue to use
    force once a         suspect is subdued"       (emphasis added) ) ; Baker,      
    4 71 F.3d at 607
    ("We have held repeatedly that the use of force after
    a suspect has been incapacitated or neutralized is excessive as a
    matter of law.").
    Moreover, a number of Courts of Appeals have held that once
    a    suspect has      been subdued,     officers may not       continue    to use
    potentially-lethal methods of restraint, such as chokeholds.                    See
    Drummond v. City of Anaheim, 
    343 F.3d 1052
    (9th Cir. ,2003); Weigel
    v.    Broad,   
    544 F.3d 1143
      (10th Cir.      2010).     This    represents   a
    sufficiently robust consensus of cases of persuasive precedent,
    and    should have      put   Officer Shipman-Meyer on notice            that   his
    continued application of          the   chokehold after Mr.          Chambers was
    subdued was excessive.
    -42-
    When viewed in a light most favorable to Plaintiff, the facts
    suggest that Mr. Chambers was already subdued and that a reasonable
    officer in that situation would have recognized that continuing to
    keep Mr. Chambers in a chokehold was unreasonable, excessive, and
    in violation of the law as it stood at the time.             For that reason
    Officer Shipman-Meyer is not entitled to qualified immunity.
    b. The Plaintiff Is also Not Entitled to Swrunary
    Judgment
    Plaintiff has also moved for summary judgment on his claim of
    excessive   force   against   Officer      Shipman-Meyer.     Resolving     the
    disputed material     facts   in   favor    of   the   Defendants,   the   non-
    movants, and viewing the facts in the light most favorable to them,
    the Court concludes that the Plaintiff is not entitled to summary
    judgment.
    It is undisputed that Mr. Chambers launched a surprise attack
    on the officers,    seriously injuring one of them.             The officers
    then attempted to restrain him, but their punches and pepper spray
    had little effect on him.      Instead, Mr. Chambers used his super-
    human strength to drag them backwards into the apartment,                  where
    they all fell to the ground.       As the officers were outmatched and
    unable to control Mr. Chambers, Officer Shipman-Meyer used a last-
    ditch maneuver to bring him to the ground.             He immediately placed
    him in a carotid hold, which lasted the minimum time necessary to
    -43-
    render Mr. Chambers unconscious, no more than twenty seconds.                   At
    that point,       with Mr.   Chambers finally subdued,          Officer Shipman-
    Meyer released the hold,           and his fellow officers handcuffed Mr.
    Chambers.
    Under those facts, a rational jury could conclude that Officer
    Shipman-Meyer reasonably feared for his own life and those of his
    fellow officers and,         therefore,   that his use of a chokehold was
    objectively reasonable.          It is true that both Griffith and Thompson
    suggest that resisting arrest, even when done violently, does not
    justify     the   use   of   a   chokehold       on   an unarmed   suspect.    See
    Griffith,    
    473 F.3d 650
    and Thompson,               
    2004 WL 1197436
    .    However,
    unlike those cases, Mr.           Chambers was able to seriously injure -
    with his bare hands alone - at least one of the officers.                Moreover,
    if the officers'        testimony is credited, he possessed super-human
    strength - possibly as a result of his consumption of PCP - that
    prevented them from controlling him in order to make an arrest.
    Given those additional factors,              a   jury could conclude that Mr.
    Chambers possessed a         threat to the lives of the officers,             even
    though he was unarmed.           In light of this threat, a jury could find
    that a chokehold was the only available means to gain control of
    Mr.   Chambers and that Officer Shipman-Meyer's decision to do so
    until Mr. Chambers was subdued was objectively reasonable.
    -44-
    ...
    In addition, Plaintiff cannot demonstrate that the right to
    be free of force under these circumstances was clearly established
    at   the   time    of   the   incident.       Specifically,       Plaintiff     cannot
    demonstrate that a reasonable officer would be on notice that he
    was prohibited from using a            chokehold on a violently resisting
    suspect    who he       and his   fellow officers         were unable      to   subdue
    through other means.          Plaintiff has not identified any controlling
    case in this Circuit that addresses a similar factual scenario.
    Virtually all of the cases from other Circuits address a scenario
    in   which   the    officers      proceeded    to   use    a    potentially     lethal
    restraint after the subject was subdued.
    Whether Officer Shipman-Meyer continued to choke Mr. Chambers
    after he had been subdued is the key fact in the qualified immunity
    analysis.     But it is also one of the central facts in dispute.
    Accordingly, neither the Defendants nor Plaintiff are entitled to
    summary judgment on the qualified immunity issue because this case
    "presents the exceptional situation in which the                    []   court cannot
    complete its qualified immunity analysis without first determining
    disputed material facts." Maestas v. Lujan,                    
    351 F.3d 1001
    , 1009-
    10 (10th Cir. 2003) . 11
    11   However, that "does not mean that the officers cannot reassert
    their qualified immunity claims at and after trial when the factual
    disputes have been resolved."   
    Dixon, 922 F.2d at 1463
    ; see also
    Figueroa-Rodriguez v. Aquino, 
    863 F.2d 1037
    , 1041 n. 5 (1st Cir.
    -45-
    2. Neither Party Is Entitled to Sununary Judgment on
    the Claims of Bystander Liability
    Plaintiff also argues that the other officers, LaDuca, Rose,
    and Karabelas, can be held liable for Officer Shipman-Meyer's use
    of a chokehold because they failed to intervene to stop him from
    violating Mr.       Chamber's    rights.        P1 . ' s   Opp' n   at   25 - 26 .   Both
    parties have moved for summary judgment on this claim, but because
    there are issues of material fact in dispute,                       neither party is
    entitled to it.
    "[A] plaintiff can show that        [an] officer is liable under a
    theory of bystander liability. Under that theory,                        an officer is
    held liable for a constitutional violation if he:                        (1) knows that
    a   fellow   officer     is   violating    an      individual's          constitutional
    right;    (2) has a reasonable opportunity to prevent the harm; and
    (3) chooses not to act."         Matthews v. District of Columbia, 730 F.
    Supp.    2d 33,   39   (D.D.C.   2010)   (internal citations and quotation
    marks omitted); see also Moore v. District of Columbia, 
    79 F. Supp. 3d
    121, 134-35 (D.D.C. 2015).
    In this case,    there are significant issues of material fact
    in dispute that preclude judgment for either side.                        As discussed
    above, a jury could reasonably conclude from the record: 1) that
    1988) ("A defendant who has appropriately pleaded the affirmative
    defense of qualified immunity may establish his right to immunity
    at any point in the proceeding, including at trial.").
    -46-
    Officer Shipman-Meyer held Mr. Chambers in a chokehold despite the
    fact    he   was    subdued;    2)     that     this   chokehold   lasted   for   a
    significant period of time after Mr. Chambers was subdued; and 3)
    given the amount of time Mr. Chambers was in the chokehold and the
    fact that the other officers were mere feet from what transpired,
    that they saw all of this.
    First, should a jury resolve those questions in favor of the
    Plaintiff,    all    three elements of bystander liability would be
    satisfied.     The three other officers were present for the entire
    sequence of events,         and thus,        may well have observed everything
    that Officer Shipman-Meyer did, contrary to their denials. 12                 What
    is more, the Court has already concluded that the right to be free
    of     excessive    force      under     these     circumstances    was     clearly
    established at the time.             Thus,    if a jury concluded that Officer
    12 The Defendants argue that because the other officers deny even
    seeing Officer Shipman-Meyer use a chokehold, they cannot be held
    liable under a bystander liability theory.   If that fact was not
    in dispute, as they assert, they would be correct.     But as the
    Court has already discussed, there is reason to doubt the other
    officers' accounts.
    When viewed in a light most favorable to Plaintiff, the facts
    suggest that some if not all of the other officers saw Officer
    Shipman-Meyer use a chokehold.    Again, the facts suggest that he
    may have employed the chokehold for minutes.    While it was used,
    the other officers were within feet, perhaps inches, of Officer.
    Shipman-Meyer.    Under those circumstances, the other officers'
    testimony that they did not see any use of a chokehold is
    implausible.
    -47-
    Shipman-Meyer    used   excessive   force,    it    could   also   reasonably
    conclude that the other officers knew that Officer Shipman-Meyer
    was violating Mr. Chambers' constitutional rights.
    Second, given that Mr. Chambers was subdued by the officers,
    when the facts are viewed in a light most favorable to Plaintiff,
    a jury could also reasonably conclude that the other officers had
    a   reasonable   opportunity   to   prevent   the    violation     by    getting
    Officer Shipman-Meyer to release the chokehold.             Third,      there is
    no evidence in the record that any of the officers did anything to
    get Officer Shipman-Meyer to end the chokehold.             Indeed, they all
    deny ever seeing him use a chokehold, which necessarily forecloses
    them from arguing that they attempted to stop it.
    By the same token, when the facts are viewed in a light most
    favorable   to   the other officers,       Plaintiff ·is not entitled to
    summary judgment.       Given that the chokehold may have lasted no
    more than fifteen to twenty seconds and that the officers claim
    they were all attempting to restrain Mr. Chambers during the midst
    of a violent struggle, a jury could reasonably credit the officers'
    testimony that they did not see Officer Shipman-Meyer place Mr.
    Chambers in a chokehold.     If the other officers did not see Officer
    Shipman-Meyer use the chokehold,       Plaintiff cannot show that they
    were aware that his rights were being violated.               That alone is
    -48-
    sufficient to defeat Plaintiff's theory of bystander liability,
    and thus precludes summary judgment on his behalf.
    Consequently, neither party is entitled to summary judgment
    on the claim of bystander liability against Officers LaDuca, Rose,
    and Karabelas.
    B. Claims Based on DC Law
    The remainder of Plaintiff's claims are brought pursuant to
    the laws of the District of Columbia.                 The Court begins with Count
    Two, claiming that the officers committed an assault and battery.
    FAC at `` 14-17.           Next,     the Court turns to Count One,         claiming
    that Officer Shipman-Meyer was negligent in his use of a chokehold.
    FAC at `` 8-13.           The Court then addresses Count Five,             claiming
    that the District was negligent in its training of officers on the
    use of chokeholds.          FAC   ``at     26-32.    Finally, the Court addresses
    Count Four, claiming wrongful death.                 FAC at `` 23-25.
    1. Count Two: Assault and Battery
    Plaintiff         alleges    tha,t   each of    the   officers   committed an
    assault and battery in violation of District of Columbia law.                    He
    advances two theories of liability in support of this claim.                  Pl.'s
    Opp' n at 2 7 - 2 8 .     First,     Plaintiff argues that Officer Shipman-
    Meyer's use of a chokehold constitutes assault and battery.                     
    Id. Second, Plaintiff
    argues that if Officer Shipman-Meyer's use of a
    -49-
    chokehold    constitutes      assault     and       battery,         Officers         LaDuca,
    Karabelas,   and Rose also committed assault and battery because
    they aided and abetted him.             
    Id. Both parties
    have moved for
    summary judgment.
    a. Neither Party Is Entitled to Summary Judgment
    on the Claim that Officer Shipman-Meyer
    Committed Assault and Battery
    Defendants argue that Officer Shipman-Meyer had a qualified
    privilege    to use    a    chokehold on Mr.           Chambers        and    that     he   is
    therefore entitled to summary judgment.                 Defs.' MSJ at 19-21.
    Just as qualified immunity is a shield against liability in
    Section 1983 excessive force claims, qualified privilege protects
    officers in common law claims of assault and battery.                         District of
    Columbia v Chinn,      
    839 A.2d 701
    ,          705-06    (D.C.        2003).     "A police
    officer has a qualified privilege to use reasonable force to effect
    an arrest, provided that the means employed are not in excess of
    those which the actor reasonably believes to be necessary.                       11
    Scales
    v. District of Columbia, 
    973 A.2d 722
    , 730 (D.C. App. 2009). "[T]he
    test for qualified privilege in an assault and battery suit is
    both   subjective     and   objective:        the   officer          must     subjectively
    believe that he or she used no more force than necessary, but the
    officer's judgment is compared to that of a hypothetical reasonable
    police officer placed in the same situation.                    11
    
    Id. at 730.
           The
    objective piece of the qualified privilege analysis is "similar to
    -50-
    the excessive force standard applied in the Section 1983 context."
    Dormu v. District of Columbia, 
    795 F. Supp. 2d 7
    , 27 (D.D.C. 2011).
    In addressing      Plaintiff's     Section 1983          claims,    the     Court
    concluded that a rational jury could conclude that Officer Shipman-
    Meyer' s use of a chokehold was not objectively reasonable. That
    conclusion applies with equal           force    to the        claim of qualified
    privilege.     Accordingly, Officer Shipman-Meyer is not entitled to
    qualified privilege on Plaintiff's assault and battery claim at
    the summary judgment stage.
    Plaintiff is also not entitled to summary judgment on his
    assault and battery claim.         In his deposition,            Officer Shipman-
    Meyer testified       to his   subjective       fear     for   his   life.      Defs.'
    Analysis of Material Facts at      ~    24.   And, as discussed above, when
    the evidence is viewed in a light most favorable to the Defendants
    a   rational   jury    could   conclude       that       his   use   of   force     was
    objectively    reasonable.      Accordingly,         a    jury could      reasonably
    conclude that Officer Shipman-Meyer had a qualified privilege to
    place and maintain a chokehold on Mr. Chambers.
    Consequently, neither party is entitled to summary judgment
    on the issue of whether Officer Shipman-Meyer committed assault
    and battery.
    -51-
    b. Defendants Are Entitled to Summary Judgment on
    the Claim that the other Three Officers
    Committed Assault and Battery
    Defendants argue that they are entitled to summary judgment
    on Plaintiff's theory that one or more of the other three officers
    - Karabelas, LaDuca, or Rose - aided and abetted Officer Shipman-
    Meyer because it is without merit.
    In the District of Columbia, a person aiding or abetting the
    principal of fender in the commission of a crime is held as liable
    as the principal.         D.C. Code     §    22-1805.       "Aiding and abetting is
    established if the accused 'in some sort associated himself with
    the venture, participated in it as in something that he wished to
    bring    about,    and    sought   by   his        action   to    make   it   succeed. '"
    Hackney v. U.S.,         
    389 A.2d 1336
    , 1342           (D.C.     1978), cert. denied,
    
    439 U.S. 1132
       (1979)    (internal citations,               quotation marks,    and
    ellipses omitted).        However, to prove that a person is an accessory
    who aided and abetted the principal, "there must exist a community
    of unlawful intent between the accessory and the perpetrator of
    the crime."       
    Id. Plaintiff's aiding
    and abetting claim is without any merit
    because he has presented no evidence establishing a community of
    unlawful intent between Officer Shipman-Meyer and any of the other
    three officers.          There is no evidence that any of these three
    shared an intent with Officer Shipman-Meyer that he unnecessarily
    -52-
    choke,   let   alone   harm,    Mr.    Chambers.             At   best,     the   evidence
    suggests that they intended to restrain Mr.                       Chambers, which was
    entirely lawful given his assault of the officers, and that when
    Officer Shipman-Meyer used a            chokehold to do so,                 they did not
    actively intervene once it became clear that the chokehold was no
    longer necessary.         Those facts are insufficient to establish the
    requisite criminal state of mind on the part of any of the other
    officers.
    Therefore, Defendants are entitled to summary judgment on the
    claim that Officers Karabelas, LaDuca, and Rose aided and abetted
    an assault and battery.
    2. Count One: Claim of Negligence by Officer Shipman-
    Meyer
    Plaintiff alleges in his First Amended Complaint that Officer
    Shipman-Meyer's use of a chokehold violated a national standard of
    care and was therefore negligent.                  FAC at    ~   11.
    "[A]   municipality      may    choose        to   hold      its    officers    to   a
    stricter standard than the Cons ti tut ion requires."                     Scales v. D. C. ,
    
    973 A.2d 722
    ,   730     (D.C.    App.     2009)         (internal     citations    and
    quotation marks omitted) .           Thus,    even where an officer does not
    violate a suspect's constitutional rights, he may still be liable
    under a different, heightened standard of care that is established
    by the District of Columbia.                 
    Id. "In order
    to prevail on a
    -53-
    negligence cause of action, the plaintiff must prove the applicable
    standard of care, a deviation from that standard by the defendant,
    and     a    causal      relationship      between      that     deviation    and       the
    plaintiff's injury."           
    Id. Plaintiff argues
    that the District of Columbia Limitation on
    the Use of the Chokehold Act of 1985 ("Chokehold Act"), D.C. Law
    6-77, establishes such a heightened standard of care.                         First, it
    prohibits officers from ever using tracheal holds.                      DC Code Ann.
    §    5-125. 03 (a) .     Second,   it prohibits officers from using carotid
    holds unless: 1) an officer has been trained in the use of carotid
    holds; and 2)          lethal force is necessary to protect the life of a
    civilian or another officer.              
    Id. at§§ 5-125.03
    (a), (a) (1).          Third,
    it    requires     an officer who has             used a   carotid hold to render
    immediate first aid and medical treatment to the suspect if he
    becomes      unconscious      as     a   result    of   the    hold.    
    Id. at §
       5-
    125. 03 (a) (2).
    In Plaintiff's Motion for Summary Judgment, he advances three
    distinct theories of negligence based on the Chokehold Act.                        First,
    he argues that Officer Shipman-Meyer applied a tracheal hold to
    Mr. Chambers, and that this was negligent in light of the statute's
    prohibition on tracheal holds.              Pl.'s MSJ at 8-11.         Alternatively,
    he argues that even if Officer Shipman-Meyer used a carotid hold,
    he was negligent because he had not received training on the use
    -54-
    of carotid holds, which is a prerequisite to their use.                            Pl.'s MSJ
    at   17-18.       Finally,     he    argues     that Officer Shipman-Meyer was
    negligent because he failed to immediately provide first aid and
    emergency medical treatment to Mr. Chambers after he was subdued
    as required by the Chokehold Act.                   Pl.'s MSJ at 18-19. Plaintiff
    has moved for summary judgment on all three theories.
    Defendants       have     also     cross-moved        for    summary         judgment.
    First,    they     argue     that     Plaintiff      cannot       state      a    claim    for
    negligence,       because     the    allegedly negligent           conduct         is   wholly
    subsumed within his assault and battery claim.                         Defs.' MSJ at at
    21-22.      Second,    Defendants argue that            -   as a matter of              law -
    Officer Shipman-Meyer did not proximately cause injuries to Mr.
    Chambers,     because Mr.       Chambers'       assault of the officers was an
    intervening and superseding cause of his injuries.
    a. Plaintiff's Negligence Claim Is Distinct from
    his Assault and Battery Claim
    Defendants argue          that     Plaintiff cannot          state a         claim for
    negligence that is distinct from his claim for assault and battery.
    Defs'.    MSJ at 21-22        (citing District of Columbia v.                     Chinn,   
    839 A.2d 701
    , 711 (D.C. 2003)).
    "Under    District         of    Columbia      law,       a      plaintiff        who
    simultaneously        asserts       claims    for    negligence        and       assault   and
    battery based on excessive force must ensure that the negligence
    -55-
    claim is:          (1)   'distinctly pled;'      (2)   'based upon at     least one
    factual scenario that presents an aspect of negligence apart from
    the     use   of     excessive   force   itself;'      and   (3)    'violative   of   a
    distinct standard of care.'" Dormu v. D.C., 795 F. Supp. 2d at30
    (quoting 
    Chinn, 839 A.2d at 711
    )         .13
    Contrary to Defendants' argument, Plaintiff satisfies Chinn's
    three requirements. First, Plaintiff has pled his negligence claim
    separately from his claims for assault and battery. See FAC at                        ``
    8-13,    14-17      (setting forth distinct claims for negligence,               Count
    One, and assault and battery, Count Two).
    Second, all three of Plaintiff's theories of negligence are
    "based upon at least one factual scenario that presents an aspect
    of negligence apart from the use of excessive force itself."                     Chinn
    at 711.             Plaintiff argues that Officer Shipman-Meyer violated
    this standard of care by mistakenly employing a tracheal chokehold
    when,    at most, a carotid hold was aut.horized.                  This claim shares
    one of the features the Chinn court identified as common in cases
    13 "These requirements stem from the different states of mind that
    each theory of liability requires. Battery and assault are
    intentional torts. Negligence is not.    'Intent and negligence are
    regarded as mutually exclusive grounds of liability. As the saying
    goes, there is no such thing as a negligent battery.'      The D.C.
    Court of Appeals has nonetheless held that there are 'certain
    circumstances in which the events surrounding the application of
    excessive force may lend themselves to a theory of negligence as
    well' as assault and battery. 
    Dormu, 795 F. Supp. 2d at 30
    (quoting
    
    Chinn, 839 A.2d at 706-07
    ).
    -56-
    where plaintiffs have been allowed to proceed, namely a possible
    'misperception of fact.' See 
    Chinn, 839 A.2d at 711
    ; Dormu, 795 F.
    Supp. 2d at 30.           Whether Officer Shipman-Meyer knew he was using
    a tracheal hold rather than a carotid hold is the kind of factual
    mistake relevant to whether he acted negligently.
    Alternatively, Plaintiff argues that if Officer Shipman-Meyer
    us,ed a carotid hold, he violated the standard of care because he
    was not trained in their use as                 required by statute.           Whether
    Officer Shipman-Meyer was trained in the use of carotid holds is
    factually distinct from the question of whether the circumstances
    made it reasonable to place Mr. Chambers in a carotid hold in the
    first place.        For the very same reason, Plaintiff's argument that
    Officer Shipman-Meyer failed to treat Mr.               Chambers after he had
    been     subdued     is    totally     factually    distinct    from     the     facts
    underlying his assault and battery claim.
    Third,      Plaintiff's       allegations    satisfy    the     final     Chinn
    requirement that there be a violation of a "distinct standard of
    care."     
    Chinn, 839 A.2d at 711
    .          Plaintiff alleges that District
    of Colmbia law establishes a distinct standard of care with regard
    to the use of force - prohibiting the use of tracheal holds in all
    instances and only authorizing the use of carotid holds by officers
    who have been trained.         This is distinct from the standard of care
    -57-
    under his assault and battery claim, which requires'only that the
    officer's use of either type of chokehold be reasonable under the
    circumstances.         Plaintiff's failure-to-treat claim alleges that
    officers who employ carotid holds are required to treat a suspect
    after    they   have    been    subdued,    which    is    obviously     a    distinct
    standard of care than whether an officer's use of a carotid hold
    is reasonable.
    Consequently,    Plaintiff's claims that Officer Shipman-Meyer
    acted negligently are distinct from his assault and battery claims.
    b. The Court Will Not Resolve at this Time
    Defendants'  Argument   that   Mr. Chamber's
    Intentional   Acts   of   Violence  Were   a
    Superseding Cause of his Injuries
    Defendants also argue that even if Plaintiff could establish
    that    Officer    Shipman-Meyer        caused    Chambers'    death,        Chambers'
    original assault on the officers was a superseding cause of his
    own injuries, and therefore that Plaintiff cannot succeed on his
    negligence claim as a matter of law.              Defs.' MSJ at at 22-24.
    "In order to prevail. on a negligence cause of action," one of
    the    necessary   elements      a    plaintiff     must   prove    is       "a   causal
    relationship between that deviation and the plaintiff's injury."
    
    Scales, 973 A.2d at 730
    .             "D.C. follows the black-letter tort law
    principle that an intervening force breaks the chain of proximate
    causation       when     that     intervening        force     is      sufficiently
    -58-
    unforeseeable as to constitute a superseding cause."              Hundley v.
    District of Columbia,     
    494 F.3d 1097
    ,    1104-05     (D.C.    Cir.   2007).
    The commission of a crime is ordinarily such an intervening force.
    
    Id. Consequently, Defendants
    argue     that as     a matter of       law,
    Officer Shipman-Meyer's conduct cannot be a proximate cause of
    Plaintiff's injuries, because Mr. Chambers intentionally assaulted
    the officers and that assault was not foreseeable.
    Plaintiff counters that the Chokehold Act establishes the
    relevant standard of care,      and on its face,        the Chokehold Act
    appears to fully foresee violent conduct such as that committed by
    Mr. Chambers.     A statute or regulation may establish the relevant
    standard of     care where   its purpose   is,   in part,       to protect a
    particular class of persons or to protect against a particular
    type of harm.      See Restatement   (Second)    of Torts    §   286    (1965).
    "At a minimum [] the statute or regulation relied on must promote
    public safety and have been enacted to protect persons                  in the
    plaintiff's   position or to prevent       the   type   of   accident      that
    occurred." See McNeil Pharm. v. Hawkins, 
    686 A.2d 567
    , 579                (D.C.
    App. 1996)
    The Chokehold Act appears to be precisely this kind of public
    safety statute.     The Chokehold Act establishes strict limits on
    the use of chokeholds by the police.       See DC Code Ann.      §§    5-125.01
    -59-
    - 5-125.03.           These limits were established because the District of
    Columbia        Council           determined       that        the    unrestricted   use    of
    chokeholds "presents an unnecessary danger to the public." 
    Id. at §
       5-125.01.     Thus, the text of the statute suggests it was designed
    to    "prevent        the    type of       accident       that occurred."        See McNeil
    
    Pharm., 686 A.2d at 579
    .
    Moreover,           the    text    of     the    statute      suggests   that     these
    protections were intended to apply to individuals in Mr. Chambers'
    position.         The Chokehold Act categorically bans the use of tracheal
    ·holds "by any police officer ... under any circumstances."                              DC Code
    Ann.     §   5-125. 03 (a).         It also bans the use of carotid holds, "except
    under those circumstances .and conditions under which the use of
    lethal force is necessary to protect the life of a civilian or a
    law enforcement officer."                    
    Id. Thus, on
    its face, the Chokehold Act contemplates that police
    officers may confront an individual who is so violent,                                that she
    poses a threat to the life of the officer or others.                               Even under
    such         extreme     circumstances,            the    Chokehold      Act   establishes     a
    standard of care police must comply with by: 1) prohibiting the
    use of         tracheal       holds;       and 2)       only allowing carotid holds by
    officers        trained        in    their       use.      In    all   other   circumstances,
    including those where a suspect is violent but does not threaten
    -60-
    the lives of the officers or others, the Chokehold Act bars police
    officers from using either tracheal or carotid holds.
    Thus,    in enacting the Chokehold Act, the Council appears to
    have   fully     foreseen the      situation presented in this              case    a
    suspect violently resisting the police - and it prescribed specific
    rules of       conduct   for   the police         to follow for     the purpose of
    protecting       that    violent    individual        from   the   harm     posed   by
    chokeholds.        Accordingly,      Mr.    Chambers'     assault of      the police
    officers does not appear to be an             unforeseea~le,       superseding act.
    Of course,       this all presumes that the Chokehold Act is in
    fact a public safety statute that establishes a distinct standard
    of care.       Whether that is the case appears to be a question of
    first impression.           Resolution of that question is a                "purely a
    judicial [decision], for the court to make," based on a detailed
    inquiry into the statute's purposes.                 See McNeil 
    Pharm., 686 A.2d at 579
    (internal citations and quotations omitted) .
    Unfortunately,      the     answer    to    that   question    has    received
    little, if any, briefing on the merits by the Parties. In his First
    Amended Complaint, Plaintiff alleged that the Defendants' conduct
    was negligent because it violated a                  "national standard of care
    required of Police Officers in such circumstances."                    FAC at ~ 11.
    However, a statute of the District of Columbia cannot establish a
    -61-
    national      standard    of    care,   and    therefore   his     First    Amended
    Complaint did not properly raise this argument.                  It was not until
    he    filed his Motion for Summary Judgment             that Plaintiff         first
    argued that the Chokehold Act established the governing standard
    of care.
    The Court may disregard a claim raised for the first time in
    a memorandum of law.           Tunica-Biloxi Tribe of La. v. U.S., 577 F.
    Supp. 2d 382, 411 (D.D.C. 2008).              However, it is inappropriate to
    strike the newly-raised claim if the "factual basis for [her] new
    claim is substantially similar" to a claim already alleged in her
    complaint.     Wiley v. Glassman, 
    511 F.3d 151
    , 159 (D.C. Cir. 2007).
    If    the   court dismisses      the newly-raised claim,          the court must
    afford the plaintiff leave to amend her complaint to include it.
    See Tunica-Biloxi 
    Tribe, 577 F. Supp. 2d at 411
    .
    Given that this is a question of first impression, involving
    the interpretation of a statute of the District of Columbia, and
    the    absence    of     substantive     briefing,    Plaintiff's          claim   of
    negligence based on violations of the Chokehold Act is not properly
    before the Court and the Court will not consider it.                       Plaintiff
    -62-
    may seek leave to amend his First Amended Complaint to include
    this claim. 14
    However, with regard to Plaintiff's existing negligence claim
    contained in Count One of the First Amended Complaint, Plaintiff
    has not even attempted to establish the existence of a national
    standard of care, let alone succeeded.        Accordingly, Defendants'
    Motion for Summary Judgment on this claim will be granted,         and
    Plaintiff's Motion for Summary Judgment on this claim will be
    denied.
    3. Count Five: Neither Party Is Entitled to Surrunary
    Judgment on the Claim of Negligent Training by the
    District of Columbia
    Plaintiff also alleges that the District was negligent in
    failing to train its officers as to when chokeholds were authorized
    under the Chokehold Act.      FAC at 26-32.
    14   Plaintiff has also moved for summary judgment on the issue of
    whether Defendants may assert the defenses of contributory
    negligence and assumption of the risk.       Pl.' s MSJ at 27-28.
    Whether these defenses bar Plaintiff's negligence claim hinges on
    whether the Chokehold Act is a public safety statute.    Martin v.
    George Hyman Const. Co., 
    395 A.2d 63
    , 69-74. (D.C. App. 1978)
    (assumption of the risk and contributory negligence are not a bar
    to a claim of negligence based on deviation from a standard of
    care established by a public safety statute). Accordingly, these
    arguments cannot be resolved unless and until Plaintiff amends his
    Complaint.
    -63-
    a. Defendants  Are   not  Entitled  to   Sununary
    Judgment because Mr. Chambers Conduct Was not
    a Superseding Act
    Defendants have moved for summary judgment, arguing that Mr .
    .   1
    Chambers'    assault on the police officers was an intervening and
    superseding    factor    and   that   Plaintiff    cannot   show     causation.
    Defs.' MSJ at 23-24.      They contend that the D.C. Circuit's decision
    in Hundley prevents a plaintiff who assaults a police officer from
    bringing a claim of negligent training against MPD because the
    plaintiff's violent conduct was a            superseding cause of her own
    injuries.     See Defs.' MSJ at 23-24         (citing 
    Hundley, 494 F.3d at 1104-05
    ).
    The Defendants' arguments make far too much out of Hundley,
    which announced a       fairly limited principle:        when an officer is
    negligent in initially seizing an individual, it is not foreseeable
    that the person seized will violently assault the 
    officer. 494 F.3d at 1104-05
    .    Therefore,    the    officer's   original    seizure
    however negligent - is not the proximate cause of any harm that
    results from the officer's subsequent use of force.              
    Id. In contrast,
    it should be foreseeable to any police department
    that its officers,      in the regular course of duty, will encounter
    individuals who commit crimes, including assault on the officers
    themselves.     Because violence against officers is foreseeable at
    -64-
    the departmental-level, police department policies on the use of
    force must appropriately train the officers on how to respond.
    Indeed,    the   history    of   negligent    training    claims        in    the
    District suggests that Hundley does not have the reach Defendants
    claim.      Plaintiffs     in the District of        Columbia have regularly
    advanced claims that MPD was negligent in training its officers.
    In many of those cases, the plaintiff first assaulted the officer
    before the allegedly excessive force was used.                  Yet,   the courts
    have not barred those claims on the principle that the plaintiff's
    criminal activity was a superseding cause of their injuries.                         See
    e.g.   District of Columbia v.          Peters,   
    527 A.2d 1269
           (D.C.    1987)
    (plaintiff who struck officer before officer used force able to
    proceed on negligent training claim only if he introduced expert
    testimony);      District of      Columbia v.     White,   
    442 A.2d 159
                (D.C.
    1982) .
    As this is the only basis on which Defendants have moved
    for summary judgment on this count, their Motion must be denied.
    b. Plaintiff Is Not Entitled to Swnmary Judgment
    because He Cannot Establish Causation
    Plaintiff has also moved for summary judgment, asserting that
    it is "axiomatic" that MPD's failure to train its officers on the
    use of force was negligent. Indeed, Plaintiff appears so sure of
    -65-
    his claim that he has failed to cite to a single case or proposition
    of law in support.          See Pl.'s MSJ at 26-27.
    As stated above,           "in order to prevail on a negligence cause
    of action,        the plaintiff must prove the applicable standard of
    care, a deviation from that standard by the defendant, and a causal
    relationship between that deviation and the plaintiff's injury."
    
    Scales, 973 A.2d at 730
    .           Plaintiff can satisfy the first two
    elements but not the third.
    Plaintiff's expert provided his opinion that                       the national
    standard of care requires a police force to train its officers on
    applicable        laws    and     policies      governing    the    use     of   force.
    Supplemental Expert Report by Robert Klotz                  ("Klotz Report), Exh.
    14    to Pl.' s    MSJ    [Dkt.    No.   56-1].    He further opined that MPD
    deviated from that standard of care, because MPD does not properly
    train officers on the limitations established in the Chokehold
    Act.    
    Id. (noting that
    MPD has itself identified improper training
    as a problem (citing District of Columbia, Police Complaints Board,
    Improving MPD' s         Policy on the Use of Chokeholds and other Neck
    Restraints           (August             10,       2015)           (available        at
    https://policecomplaints.dc.gov/chokeholds-neckrestraints))).
    However,     Plaintiff       cannot     establish that      this    failure-to-
    train caused Mr. Chambers' injuries.               When the facts are viewed in
    a    light most     favorable       to Defendants,     a    jury could reasonably
    -66-
    ...
    conclude that Mr.        Chambers posed a         threat   to the    life of the
    officers.        Given that   threat,      the Chokehold Act authorizes an
    officer to use a carotid hold to subdue a suspect, which is what
    Officer Shipman-Meyer claims he did.              Accordingly, even if Officer
    Shipman-Meyer had been properly trained, Mr. Chambers might still
    have died, in which case the failure-to-train was not the cause of
    his injuries, and Plaintiff is not entitled to Summary Judgment.
    4. Count Four: The Defendants Are not Entitled to
    Summary Judgment on Plaintiff's Wrongful Death
    Claim
    Plaintiff has not moved for summary judgment on their wrongful
    death claim but Defendants have done so.
    Plaintiff's wrongful death claim is based on D.C. Code                §   16-
    2701.      The    Parties   agree   that     to   succeed under      the   statute,
    Plaintiff must prove both: 1) an "underlying tort                  (common law or
    constitutional);" and 2) "injury to the survivor," here Mr. Ingram.
    Defendants argue that they are entitled to summary judgment
    because Plaintiff cannot show any underlying tort.                  Defs.' MSJ at
    24-25.     However,     as discussed above,          Plaintiff certainly has a
    viable    claim    of   assault     and    battery    under   DC    law.   That    is
    sufficient to maintain his claim for wrongful death.                 Accordingly,
    Defendants are denied summary judgment on this Count.
    -67-
    IV.   CONCLUSION
    For the foregoing reasons,      the judgment of the Court is as
    follows:
    Plaintiff's Motion for      Summary Judgment    is   denied in its
    entirety;
    Plaintiff's claims that Officer Shipman-Meyer's conduct was
    negligent,   in light of     a   standard of   care established by the
    Chokehold Act,     were improperly raised for the first        time in a
    memorandum of law and are not properly before the Court;
    Nonetheless,     Plaintiff may seek leave to further amend its
    First Amended Complaint to include these negligence claims;
    Defendant's Motion for Summary Judgment is granted in part,
    as to Count One of Plaintiff's First Amended Complaint, in so far
    as it alleges negligence based on violation of a national standard
    of care, and as to Count Two, in so far as it alleges that Officers
    Karabelas,   LaDuca,    and Rose aided and abetted Officer Shipman-
    Meyer's assault and battery of Mr. Chambers, and denied in part,
    as to all other remaining Counts.
