    PILLARD, Circuit Judge: Gregory Burley, an African-
    American train engineer, claims that his employer, the
    National Passenger Railroad Corporation (Amtrak),
    discriminated against him because of his race in violation of
    Title VII and the District of Columbia Human Rights Act.
    After the engine Burley was driving passed a stop signal at
    the rail yard and was forced off the rails by a safety derailer,
    Amtrak fired him and suspended his engineer certificate. The
    district court granted Amtrak’s motion for summary
    judgment. Burley contends that was error because Amtrak’s
    entire investigation of the derailment was so patently flawed,
    and the discipline it imposed on him so disproportionate, that
    a jury could infer that Amtrak engaged in intentional racial
    discrimination. Amtrak defends the discipline on the ground
    that passing a signal in a work area is a serious infraction
    likely to cause serious injury or death to workers on or around
    the tracks, even if no one was injured in this case and the
    property damage was only modest. Amtrak also relies on the
    undisputed evidence that the official who decided on the
    severity of the discipline was unaware of Burley’s race. We
    have carefully examined the record and Burley’s arguments.
    Because no jury could reasonably conclude based on the
    evidence in the record that Amtrak was motivated by Burley’s
    race to take the adverse actions of which he complains, we
    affirm.
    I.   Background
    At the time of the accident, Burley worked as an engineer
    at Amtrak’s Ivy City Maintenance Facility, a rail yard in
    Washington, D.C., where he moved rail cars around the
    facility as needed for maintenance and repair. Burley’s work
    was governed by the Northeast Operating Rules Advisory
    Committee Operating Rules (NORAC Rules). NORAC Rule
    16 states that the engineer must not allow the train to pass a
    3
    blue signal—a type of rail-yard stop sign indicating that
    workers may be on or near the track ahead and that continuing
    forward may cause serious injury or death. A blue signal
    typically consists of a blue metal flag and a flashing blue light
    to make it visible in the dark, but an engineer must stop for a
    blue signal even if there is no blue light. Blue signals may be
    accompanied by derailers, which are additional safety devices
    to protect track workers. Sometimes a blue light that
    accompanies a blue signal flag is affixed to a nearby wall, and
    sometimes a blue light is attached to the signal itself. When,
    for whatever reason, an engine fails to stop for a blue signal, a
    derailer, if present and in an “applied” position, forces the
    engine off the track before it hits anyone. NORAC Rule
    104(d) requires engineers to know the locations of permanent
    derailers and prohibits an engineer from operating over an
    applied derailer.
    In the early morning darkness of October 20, 2007, the
    engine Burley was driving at the Ivy City yard derailed.
    Burley was working with Conductor Jerry Ebersole, a white
    male, and Assistant Conductor Lawrence Mahalak. Near the
    end of their shift, the crew was instructed to move a train car
    that had undergone maintenance work on Track 7 in the
    Service and Inspection Building. As the engine approached
    Track 7 to retrieve the repaired car, Ebersole instructed
    Mahalak to dismount the engine and walk ahead in order to
    prepare the car to be towed out. Ebersole threw switches on
    the track, boarded the train, and instructed Burley to go
    forward.
    As the train moved along Track 7, Ebersole dismounted
    the slowly moving train, intending to walk ahead of the train
    to the Service and Inspection Building. Ebersole stepped
    down from the front edge of the engine where Burley could
    not see him, and did not tell Burley that he had left the train or
    4
    that the engine was approaching an applied derailer on the
    track. It is undisputed that Burley’s view of the derailer just
    ahead was blocked, given his position on the engine and the
    curve of the track. According to Burley, he did not see any
    blue signal on the track as he approached, and he noticed that
    the blue lights on the outside of the service building were not
    illuminated (as they should have been if a blue signal were
    displayed on the track). Shortly after Ebersole exited the
    train, Burley ran over the derailer and the train derailed.
    Nobody was hurt, and the property damage was not extensive.
    Because of the potential for harm to track workers,
    however, it is undisputed that Amtrak considers any blue-
    signal infraction to be extremely serious. Leslie David Smith,
    Burley’s supervisor in the Transportation Department and the
    senior Amtrak supervisor on duty at the time of the
    derailment, who is white, convened an incident committee to
    investigate. The other two members of the committee, an
    assistant superintendent in the Mechanical Department and a
    track supervisor in the Engineering Department, are African
    American. Smith inspected the scene, took photographs,
    interviewed the crew, and discussed the incident with other
    members of the Transportation Department. J.A. 153-55,
    405-06. Smith recounted that he observed a blue flag and a
    blue light, still flashing, underneath the derailed engine. He
    concluded in the committee report that the blue signal was
    displayed on the track at the time of the derailment, and that
    Burley had passed through the blue signal and over the
    derailer. Smith reported that Ebersole had exited the engine
    before the derailment. Smith apparently remained unaware,
    however, that Ebersole failed to tell Burley when Ebersole left
    the engine. Smith concluded that Burley violated safety rules.
    Amtrak brought formal disciplinary charges against
    Burley and Ebersole. Each of them requested a “waiver”—a
    5
    dispensation available under Amtrak’s disciplinary rules to an
    employee who accepts responsibility for a rule violation and
    forgoes the right to a formal investigation in exchange for a
    lesser penalty. Amtrak granted Ebersole’s request for a
    waiver, but denied Burley’s. A hearing officer then held a
    formal disciplinary hearing on the charges against Burley. At
    the hearing, Burley’s union represented him, and he had an
    opportunity to testify and cross-examine Amtrak’s witnesses.
    The hearing officer, relying in large part on Smith’s
    testimony, concluded that the evidence demonstrated that the
    blue signal was correctly displayed and that the charges
    against Burley had been proven.
    Amtrak transmitted the incident committee’s report and
    the formal hearing record to Daryl Pesce, Amtrak’s General
    Superintendent of the Mid-Atlantic Division, who was
    responsible for imposing discipline. Pesce was unaware of
    Burley’s race. He reviewed the hearing officer’s decision, the
    hearing transcript, and Smith’s report and concluded that
    Burley’s “carelessness in disregarding a Blue Signal created
    the risk of serious injury or death and thus warranted
    termination” and a thirty-day suspension of his engineer
    certificate. Pesce Decl. (J.A. 249).
    Burley appealed internally to Amtrak’s Director of Labor
    Relations, who denied the appeal, and then externally to
    Special Board of Adjustment 948, which concluded that
    Burley committed the violation, but reinstated him (with
    seniority but without back pay). Burley appealed the
    suspension of his engineer’s certificate to the Federal Railroad
    Administration’s Locomotive Engineer Review Board. The
    Locomotive Engineer Review Board found a lack of
    substantial evidence that a blue signal was properly displayed
    before the derailment, and therefore overturned the
    certification suspension.
    6
    After exhausting other remedies, Burley sued Amtrak for
    racial discrimination, seeking, among other relief, two years’
    worth of back pay. The district court granted summary
    judgment to Amtrak, Burley v. Nat’l Passenger Rail Corp., 
    33 F. Supp. 3d 61
    (D.D.C. 2014), and Burley timely appealed.
    II. Legal Standards
    Our review of a district court’s grant of summary
    judgment is de novo. Calhoun v. Johnson, 
    632 F.3d 1259
    ,
    1261 (D.C. Cir. 2011). Summary judgment is appropriate
    only if “there is no genuine dispute as to any material fact and
    the movant is entitled to judgment as a matter of law.” Fed.
    R. Civ. P. 56(a). A moving party is entitled to summary
    judgment if the nonmoving party “fails to make a showing
    sufficient to establish the existence of an element essential to
    that party’s case, and on which that party will bear the burden
    of proof at trial.” Celotex Corp. v. Catrett, 
    477 U.S. 317
    , 322
    (1986). A dispute about a material fact is “‘genuine’ . . . if the
    evidence is such that a reasonable jury could return a verdict
    for the nonmoving party.” Anderson v. Liberty Lobby, Inc.,
    
    477 U.S. 242
    , 248 (1986). In considering a motion for
    summary judgment, the court views the evidence in the light
    most favorable to the nonmoving party and draws all
    reasonable inferences in its favor. 
    Calhoun, 632 F.3d at 1261
    .
    This court, like the district court, may not make credibility
    determinations or weigh the evidence. 
    Id. Amtrak’s position
    is that it disciplined Burley based on
    an investigation showing what it considers to be an extremely
    serious infraction of safety rules, and that Burley’s race had
    nothing to do with it. In a Title VII action, once an employer
    has offered a legitimate, non-discriminatory reason for the
    challenged employment decision, the court’s inquiry focuses
    on “one central question: Has the employee produced
    7
    sufficient evidence for a reasonable jury to find that the
    employer’s asserted non-discriminatory reason was not the
    actual reason and that the employer intentionally
    discriminated against the employee on the basis of race, color,
    religion, sex, or national origin?” Brady v. Office of the
    Sergeant at Arms, 
    520 F.3d 490
    , 494 (D.C. Cir. 2008). To
    answer that question at the summary judgment stage, the court
    assesses whether “there is evidence from which a reasonable
    jury could find that the employer’s stated reason for the firing
    is pretext” and that “unlawful discrimination was at work.”
    Barnett v. PA Consulting Grp., Inc., 
    715 F.3d 354
    , 358 (D.C.
    Cir. 2013). The analysis is the same for Burley’s claim under
    the District of Columbia Human Rights Act (DCHRA). See
    
    id. Burley’s Title
    VII claims and DCHRA claims thus rise
    and fall together.
    Burley seeks to show that Amtrak’s proffered reason for
    its discipline of Burley was pretextual. He contends that
    Smith’s investigation arrived at conclusions so erroneous and
    contrary to the evidence—especially concerning the location
    and condition of any blue signal—as to suggest
    discrimination. The investigation’s failure to examine what
    Burley characterizes as key, exculpatory videotape evidence
    was, in Burley’s view, itself a ground on which a jury could
    find that Amtrak discriminated. Burley asserts that the
    investigation as a whole was little more than a shoddy cover-
    up for the real, discriminatory reason for his discipline.
    A plaintiff can establish that an employer’s stated reason
    for the adverse employment action was a pretext for
    discrimination by showing that “the employer is making up or
    lying about the underlying facts that formed the predicate for
    the employment decision.” 
    Brady, 520 F.3d at 495
    . “If the
    jury can infer that the employer’s explanation is not only a
    mistaken one in terms of the facts, but a lie, that should
    8
    provide even stronger evidence of discrimination.” Aka v.
    Wash. Hosp. Ctr., 
    156 F.3d 1284
    , 1293 (D.C. Cir. 1998) (en
    banc). A plaintiff might also establish pretext with evidence
    that a factual determination underlying an adverse
    employment action is egregiously wrong, because “if the
    employer made an error too obvious to be unintentional,
    perhaps it had an unlawful motive for doing so.” Fischbach
    v. D.C. Dep’t of Corr., 
    86 F.3d 1180
    , 1183 (D.C. Cir. 1996).
    An employer’s investigation that is so unsystematic and
    incomplete that a factfinder could conclude that the employer
    sought, not to discover the truth, but to cover up its own
    discrimination can also permit a factfinder to find pretext.
    See Mastro v. Potomac Elec. Power Co., 
    447 F.3d 843
    , 855
    (D.C. Cir. 2006). Our purpose in smoking out pretextual
    employer rationales is to discern whether prohibited
    discrimination may be a real reason for the challenged action.
    A false “mistake” or obvious omission can itself bespeak
    discrimination.
    Burley also points to the relatively lenient treatment of
    other, white employees whom he views as similarly situated
    to him as confirmation that his discipline was unjustifiably
    harsh based on his race. Evidence suggesting that the
    employer treated similarly situated persons who were not the
    same race as the plaintiff more favorably than it treated the
    plaintiff can also be probative of discrimination. See 
    Brady, 520 F.3d at 495
    .
    III. Analysis
    Burley contends that the summary judgment record could
    support a conclusion that Amtrak’s stated reason for
    disciplining him was pretextual, that Smith’s investigation
    was racially motivated, and that Smith’s tainted investigation
    affected Amtrak’s subsequent decisions to discipline him.
    9
    Specifically, Burley contends that Smith conducted an
    incomplete and unfair investigation and presented misleading
    and false conclusions that disproportionately laid the blame
    on Burley as compared to Ebersole, the white conductor on
    duty. Burley asserts that the less harsh discipline Amtrak
    imposed on white employees for what he characterizes as
    comparable disciplinary infractions confirms that its treatment
    of him was racially biased.
    To succeed on his claim, Burley must establish that his
    race was a motivating factor in Amtrak’s adverse action
    against him. See Reeves v. Sanderson Plumbing Prods., Inc.,
    
    530 U.S. 133
    , 148-49 (2000). As is frequently true, even of
    successful discrimination cases, there is no direct evidence
    here—neither documentary nor testimonial—of racial bias.
    Indeed, there is no evidence that Amtrak’s final decision
    maker on Burley’s discipline, General Superintendent Pesce,
    was even aware of Burley’s race. Burley does not dispute that
    Pesce was unaware that Burley is African American; rather,
    he contends that Smith’s discriminatory animus infected the
    disciplinary process such that discrimination was a significant
    cause of the discipline Pesce imposed. Pesce was, in Burley’s
    view, an unwitting but effective agent of Smith’s
    discrimination.
    Burley thus invokes a combination of a cat’s paw theory
    and circumstantial evidence of racial discrimination. The
    Supreme Court set forth the standard for prevailing on a cat’s
    paw theory in Staub v. Proctor Hospital, 
    131 S. Ct. 1186
    (2011).1 The plaintiff in Staub did not contend that the
    1
    Although Staub was not a Title VII case—it involved
    discrimination based on the employee’s military obligations in
    violation of the Uniformed Services Employment and
    Reemployment Rights Act of 1994, 38 U.S.C. § 4311—we have
    10
    manager who made the ultimate decision to fire him harbored
    the prohibited motive, but that his direct supervisors did, and
    that those supervisors’ bias influenced the ultimate decision
    maker. 
    Id. at 1190.
    Staub held that a plaintiff could prevail
    on such a theory “if [1] a supervisor performs an act
    motivated by [discriminatory] animus, [2] that is intended by
    the supervisor to cause an adverse employment action, and
    …[3] that act is a proximate cause of the ultimate
    employment action.” 
    Id. at 1194.
    Because Burley’s case
    founders on the absence of evidence raising a reasonable
    inference that Smith was motivated even in part by racial
    discrimination, we need not separately analyze the causal
    factors.
    A.
    Smith’s conclusions should not be credited, Burley
    asserts, because Smith drew falsely inculpatory inferences
    against Burley from the physical evidence and witness
    accounts at the scene. The principal evidence on which
    Smith’s investigative committee relied to conclude that
    Burley violated the safety rules was that, shortly after the
    accident, Smith found (and photographed) a visibly bent blue
    signal alongside a detached blinking blue light underneath the
    derailed engine. J.A. 155-56, 358-59. Based on what he saw
    and what eyewitnesses reported, Smith inferred that a blue
    signal had been correctly displayed. J.A. 366-67.
    Burley seeks to impugn Smith’s conclusion by noting
    that Smith did not see the derailment, whereas Burley was
    present and observed no blue signal. Burley also contends
    that if a blue flag and light had been in place and an engine
    struck them, they would have been destroyed, not merely bent
    acknowledged its relevance in the Title VII context. See Hampton
    v. Vilsack, 
    685 F.3d 1096
    , 1102 (D.C. Cir. 2012).
    11
    as Smith reported. In Burley’s view, the Locomotive
    Engineer Review Board’s conclusion that substantial evidence
    did not show that the blue signal was properly displayed is yet
    another sign that Smith’s contrary conclusion was racially
    motivated.
    Burley’s analysis of the record falls short of identifying
    grounds on which a factfinder reasonably could conclude that
    Amtrak’s stated rationale for disciplining him was a pretext
    for racial discrimination. We fully credit that a jury might
    fairly believe Burley’s testimony that he did not see any blue
    signal in place. We accept that a plaintiff’s own firsthand
    observations of relevant facts are probative evidence, and that
    we must not set them aside merely because they come from a
    party who necessarily has a stake in the outcome. The
    Locomotive Engineer Review Board’s assessment of the
    weight of the evidence bolsters Burley’s contention that there
    was no blue signal in place and suggests that a jury might
    similarly conclude that Smith erred in determining that Burley
    had crossed a displayed blue signal. In the circumstances of
    this case, however, the plausibility of those differing
    observations and inferences is not, without more, grounds on
    which a reasonable jury could conclude that Smith was so far
    off base as to suggest that he acted with a racial motive.
    B.
    Burley next argues that bias can be inferred because
    Smith intentionally failed to disclose a mitigating fact about
    the derailment in his investigative report and hearing
    testimony. According to Burley’s uncontradicted testimony,
    train conductor Ebersole stepped off the engine without
    warning him, leaving Burley unaware that Ebersole was not in
    a position to signal to Burley that there was a displayed blue
    signal and an applied derailer on the track ahead. J.A. 517-
    12
    18. According to Burley, if Ebersole had told him that he was
    exiting the train, the accident would not have happened.
    Smith never mentioned in either his investigative report or his
    testimony at Burley’s disciplinary hearing, however, the fact
    that Burley did not know that Ebersole was out of position at
    the time of the accident. Burley argues that is because Smith
    consciously omitted it for racially discriminatory reasons.
    Burley’s argument fails because there is no evidence that
    Smith knew Burley was unaware of Ebersole’s position.
    Ebersole did not tell Smith when Smith interviewed him
    shortly after the incident that he left the train without telling
    Burley. J.A. 633-41. Burley did not testify at his deposition
    that he or anyone else to his knowledge ever told Smith that
    Burley was unaware that Ebersole was out of position.
    Burley’s union representative did not cross-examine Smith at
    Burley’s disciplinary hearing about Smith’s failure to include
    that fact in his report. Smith testified at his deposition that he
    did not know that Ebersole had exited the train without
    informing Burley. J.A. 161. Burley’s counsel, by post-
    argument letter, notes that “[t]here is no direct evidence in the
    record that Smith knew,” see Burley 28(j) Letter (Mar. 26,
    2015), and despite the opportunity for Burley and his
    representative to develop the point, the record is devoid of
    even a circumstantial basis from which to infer that Smith
    knew when he investigated and testified at Burley’s hearing
    that Burley thought Ebersole was still on the train with him at
    the time of the accident and so would have warned him of any
    signal or applied derailer ahead. Smith’s withholding of
    mitigating evidence of which he was unaware could not
    support a determination that Smith acted with racial bias.
    13
    C.
    Burley next contends that a reasonable jury could
    conclude that Smith’s investigation was so incomplete,
    unsystematic, or biased as to suggest that Smith discriminated
    against Burley on the basis of his race. An investigation that
    “lack[s] the careful, systematic assessments of credibility” of
    the witnesses and evidence “one would expect in an inquiry
    on which an employee’s reputation and livelihood depended”
    may give rise to an inference that the employer’s reasons are a
    pretext for discrimination. 
    Mastro, 447 F.3d at 855
    . A
    reasonable jury can conclude that an employer’s reasons were
    pretextual and that discrimination was afoot if a plaintiff can
    show that an employer’s “investigation, which was central to
    and culminated in [the plaintiff’s] termination, was not just
    flawed but inexplicably unfair.” 
    Id. Smith took
    a number of steps one would expect of an
    investigator who sincerely sought to determine what actually
    happened. Within hours of the event, Smith interviewed all of
    the relevant witnesses and took their written statements. He
    formed an incident committee, inspected the accident site, and
    took photos. Smith questioned Burley and the other people
    who were working at or near the site of the derailment about
    precisely what had happened, and wrote a report that resulted
    in significant formal charges against both Burley and
    Ebersole.
    Burley has identified one investigatory step he contends
    Smith should have taken but did not: Smith should have
    reviewed videotape of the derailment. It is unclear, however,
    whether any such videotape existed. The union representative
    who appeared on Burley’s behalf at his disciplinary hearing
    contended that he was “told” in advance of the hearing “that
    security camera video of the incident existed” and that the
    14
    employee responsible for monitoring the recording equipment
    later told him “that AMTRAK had erased the tapes.” J.A. 332
    ¶ 4. Another employee testified in a deposition that “there
    should have been video of everything that went on,” “that if
    there was a derailment, [a group of Amtrak personnel] looked
    at those videos,” and that “nine times out of ten” Smith would
    have reviewed videotape if there was a derailment. J.A. 420,
    422, 423. But that witness acknowledged that he never saw
    any video of the derailment at issue here, did not see Smith
    view the video, did not know how many cameras there were
    or where they were placed, and did not know how long any
    tapes would be preserved. He asserted “I’m not the video
    man,” and identified by name and home town the long-term
    Amtrak employee who “was in control of the whole video
    system from beginning to the end of it.” J.A. 420. Burley did
    not seek to depose that employee or anyone at Amtrak who
    could speak authoritatively about video recordings, if any, of
    the yard when the derailment occurred.
    Even assuming that a relevant video recording existed,
    Smith’s failure to review it does not support an inference that
    Smith’s actions were motivated by race. Burley has not
    identified any fact that he believes the recording would have
    revealed that might have affected the disciplinary
    proceedings. The key factual omission Burley cites in
    Smith’s investigation was Smith’s failure to take into account
    that Burley was unaware that Ebersole had departed the
    engine. Smith acknowledged that Ebersole was not on the
    engine. Even a clear and well lit video taken at close range
    would not have revealed what Burley knew about Ebersole’s
    whereabouts. Smith’s investigation was not unreliable or
    otherwise “inexplicably unfair” without the video recording.
    See 
    Mastro, 447 F.3d at 855
    . In the absence of any reason to
    think that a videotape could have revealed any material
    information, no reasonable jury could conclude that failing to
    15
    obtain and review it was an error so obvious it must have been
    intentional. See 
    Fischbach, 86 F.3d at 1183
    .2
    D.
    Finally, Burley claims that Amtrak disciplined him
    significantly more harshly than other, similarly situated white
    employees whom he asserts committed infractions of
    comparable or greater gravity, and that such differential
    treatment could lead a reasonable jury to find that Amtrak
    acted with a racially discriminatory motive. Burley first
    points to Ebersole, the white conductor who was involved in
    the same derailment, whom Burley claims bore more
    responsibility for it than he did. Amtrak denied Burley’s
    request for a waiver and terminated him. By contrast, Amtrak
    granted Ebersole a waiver and suspended him for only fifteen
    days. Burley also identifies six white engineers who received
    more lenient discipline than he did for infractions he views as
    more serious. Amtrak’s more lenient treatment of Ebersole,
    and of white engineers in other incidents comparable to his
    own, Burley contends, evinces Amtrak’s racially
    2
    The non-probativeness of potential video evidence to the issue
    Burley seeks to dispute defeats Burley’s request for a spoliation
    inference. Burley argues that Amtrak’s failure to produce any
    videotape of the derailment warrants a negative inference that
    Amtrak destroyed videotapes because they were favorable to
    Burley. We have recognized that “a negative inference may be
    justified where the defendant has destroyed potentially relevant
    evidence.” Gerlich v. U.S. Dep’t of Justice, 
    711 F.3d 161
    , 170
    (D.C. Cir. 2013). But, in addition to failing to make the case that
    there were any tapes of the derailment that were destroyed, Burley
    identifies no factual ground for concluding that Smith’s failure to
    review tapes was such an obvious error as to support a
    discrimination finding, so no spoliation inference is warranted.
    16
    discriminatory motive and should have precluded summary
    judgment in Amtrak’s favor.
    The primary flaw in Burley’s attempt to show pretext
    through comparator evidence is that it is undisputed that the
    Amtrak supervisors who denied the waiver and disciplined
    Burley did not know his race. The only individuals involved
    in Burley’s disciplinary process with the power to grant or
    deny a waiver were General Superintendent Pesce and
    Superintendent Michael Sherlock, Pesce’s immediate
    subordinate. Either Pesce or Sherlock denied Burley’s waiver
    request, though the record does not make clear who. (The
    record on the waiver issue is sparse because the collective
    bargaining agreement prohibited Amtrak from keeping formal
    records about waiver decisions, and nobody at Amtrak recalls
    deciding Burley’s or Ebersole’s waiver request.) Pesce
    decided Burley’s punishment after his disciplinary hearing.
    Burley’s race could not have influenced either the decision to
    deny Burley a waiver or the decision to discharge him and
    suspend his engineer’s certificate, for it is undisputed that
    neither Pesce nor Sherlock knew Burley’s race. See J.A. 195,
    282-83 ¶ 59, 300 ¶ 59.
    Burley counters with his cat’s paw theory: Even without
    knowing Burley’s race, Pesce and Sherlock discriminated
    against him because they relied on Smith’s investigation and
    hearing testimony and thereby unwittingly gave effect to
    Smith’s bias in meting out the discipline. See Griffin v.
    Washington Convention Ctr., 
    142 F.3d 1308
    , 1312 (D.C. Cir.
    1998). As we explain above, however, that theory fails
    because Burley has not introduced evidence that could
    persuade a reasonable jury that Smith discriminated against
    Burley.
    17
    Burley does not dispute that Amtrak took blue signal
    violations particularly seriously in order to protect the safety
    of employees working on and around the tracks. Pesce and
    Sherlock each testified that he would have denied an
    engineer’s waiver request in the case of a blue signal
    violation, especially where the engineer did not accept
    responsibility, because of the severity of such an infraction.
    J.A. 183-84, 195. Pesce testified that, for the same reason,
    termination and suspension of the engineer’s certificate was
    the appropriate discipline under those circumstances.
    Burley invokes comparator evidence in an effort to
    undercut those explanations. A plaintiff can establish pretext
    masking a discriminatory motive by presenting “evidence
    suggesting that the employer treated other employees of a
    different race . . . more favorably in the same factual
    circumstances.” 
    Brady, 520 F.3d at 495
    . Amtrak’s more
    lenient disciplinary treatment of white employees who
    violated Amtrak rules does not support the inference that
    Pesce and Sherlock discriminated against Burley on account
    of his race, however, because the white employees he
    identifies are not similarly situated to him. To prove that he is
    similarly situated to another employee, a plaintiff “must
    demonstrate that [he] and the allegedly similarly situated . . .
    employee were charged with offenses of comparable
    seriousness.” Holbrook v. Reno, 
    196 F.3d 255
    , 261 (D.C. Cir.
    1999) (internal quotation marks and citation omitted); see
    Coleman v. Donahoe, 
    667 F.3d 835
    , 846-47 (7th Cir. 2012).
    “A plaintiff must also demonstrate that ‘all of the relevant
    aspects of [his] employment situation were nearly identical to
    those of the [other]’ employee.” 
    Holbrook, 196 F.3d at 261
    (quoting Neuren v. Adduci, Mastriani, Meeks & Schill, 
    43 F.3d 1507
    , 1514 (D.C. Cir. 1995)). Factors that bear on
    whether someone is an appropriate comparator include the
    similarity of the plaintiff’s and the putative comparator’s jobs
    18
    and job duties, whether they were disciplined by the same
    supervisor, and, in cases involving discipline, the similarity of
    their offenses. See 
    Coleman, 667 F.3d at 847
    .
    Ebersole is not an apt comparator because Burley has
    failed to demonstrate that he and Ebersole were similarly
    situated. Burley and Ebersole had different roles and,
    consequently, bore different responsibility for causing the
    derailment. As a conductor, Ebersole was responsible for
    overseeing the train and the crew; Burley, the engineer, was
    responsible for operating the engine. The rules required that
    Ebersole stay in a position where he could signal Burley; they
    required that Burley stop the train if the conductor was not in
    a position to signal to him.           J.A. 336.     Ebersole’s
    responsibility, if any, for the derailment derived from his
    failure to be in position. Burley’s responsibility, in contrast,
    stemmed from his driving the train over an applied derailer.
    Given the undisputed evidence of their distinct roles and the
    different nature of their violations, Burley has not genuinely
    disputed the reasonableness of Amtrak’s decision to treat
    Burley as more culpable for the accident than Ebersole.
    The other comparator evidence also fails to defeat
    Amtrak’s summary judgment motion because Burley is
    unable to demonstrate either that other white employees were
    found to have committed offenses of comparable seriousness,
    or that they were differently disciplined by the same
    supervisors who disciplined Burley. Not one of the white
    engineers he identified crossed a blue signal. Most did not
    commit offenses of even arguably comparable seriousness.
    Only one derailed a train, and he was not disciplined by Pesce
    or Sherlock. Burley’s proffered comparator evidence thus
    cannot permit a reasonable factfinder to conclude that
    Amtrak’s nondiscriminatory reason for disciplining Burley for
    passing a blue signal more harshly than it disciplined other,
    19
    white employees who committed different infractions was a
    pretext for discrimination.
    Burley contends that the mere fact that two employees
    had different titles and duties does not necessarily undermine
    the probative value of their different treatment. Burley is, as a
    general matter, correct. He relies on cases, including
    
    Coleman, 667 F.3d at 849
    , in which employees with different
    responsibilities and titles nonetheless engaged in similar
    conduct and were governed by the same rules and standards.
    But Burley’s situation is different. Burley’s conduct as
    Amtrak reasonably understood it at the time, together with the
    high stakes of a blue signal violation, carried enhanced
    culpability. For all of these reasons, Amtrak’s more serious
    discipline of Burley as compared to the other, white
    employees he identifies as putative comparators could not
    support a jury conclusion that Amtrak discriminated against
    Burley based on his race.
    Drawing every justifiable inference in Burley’s favor, as
    we must, we find no basis in the record upon which a
    reasonable factfinder could conclude that whatever
    investigative flaws or unfairness Burley may have suffered
    relating to this incident were so unexplained or otherwise
    striking as to suggest that Amtrak was motivated by Burley’s
    race to discipline him.
