    OPINION OF THE COURT
    _______________
    KRAUSE, Circuit Judge.
    3
    Not all rights have remedies, even when they are
    enshrined in the U.S. Constitution. So where Congress has
    opted to remedy specific rights in specific circumstances, we
    hesitate to interfere with that judgment by implying our own
    remedies or restricting those provided by Congress in ways it
    never intended. Here, we consider whether Appellant
    Xiaoxing Xi has a remedy available for two types of claims,
    both of which arise from the government’s investigation,
    arrest, and later-dismissed indictment alleging—mistakenly—
    that he was a “technological spy” for China. Xi, joined by his
    co-Appellants, his wife, Qi Li, and daughter, Joyce Xi, filed a
    complaint that raised two types of claims: (1) federal
    constitutional claims under Bivens v. Six Unknown Named
    Agents of Fed. Bureau of Narcotics, 
    403 U.S. 388
     (1971),
    directed at FBI Special Agent Andrew Haugen, the lead agent,
    and other unnamed officials involved in the investigation, 1 and
    (2) malicious prosecution and other torts under the Federal
    Tort Claims Act (FTCA), 
    28 U.S.C. §§ 1346
    (b), 2671–2680,
    asserted against the United States. The District Court
    dismissed both categories of claims on the Government’s
    motion, and we agree, but only in part.
    In view of evolving Supreme Court precedent declining
    to extend Bivens into the national security realm and the limited
    circumstances in which Congress has opted to provide a
    remedy, we will affirm the District Court’s dismissal of Xi’s
    Bivens claims. But his FTCA claims are another matter. The
    District Court held the Government immune from those claims
    because it determined that Xi and his family had failed to allege
    1
    For ease of reference, this opinion refers to the claims
    against Haugen and the unnamed officials, collectively, as
    claims against Haugen.
    4
    “clearly established” constitutional violations and assumed
    that this threshold for liability, applicable to qualified
    immunity analysis, also applied to the FTCA’s “discretionary
    function exception.” We clarify today, however, that the
    “clearly established” threshold is inapplicable to the
    discretionary function analysis, and because the Government
    has no discretion to violate the Constitution, FTCA claims
    premised on conduct that is plausibly alleged to violate the
    Constitution may not be dismissed on the basis of the
    discretionary function exception. We will therefore vacate the
    District Court’s dismissal of Appellants’ FTCA claims and
    remand for further proceedings.
    I.    Factual and Procedural Background 2
    Appellant Xiaoxing Xi and his wife, Qi Li, immigrated
    to the United States from China in 1989, and over the next
    twenty-five years, lived out the American Dream. Xi, who is
    an internationally acclaimed expert in the field of thin film
    superconducting technology, was eventually appointed Chair
    of the Physics Department at Temple University. Qi Li, also
    an accomplished physicist, became a professor at Pennsylvania
    State University. And together, they settled in Pennsylvania
    and began raising their two daughters.
    According to the Complaint, however, life as the family
    knew it came to a crashing halt on May 21, 2015. In the early
    morning hours, they were awakened by loud knocks. Startled
    and partially undressed, Xi answered the door, where he was
    2
    In reciting the facts, we accept the well-pleaded
    allegations in the operative Second Amended Complaint (“the
    Complaint”) as true. See Ashcroft v. Iqbal, 
    556 U.S. 662
    , 666
    (2009).
    5
    confronted by armed FBI agents who were wielding a battering
    ram and who proceeded to handcuff him. Without an
    explanation, the agents entered the house, held Qi Li and the
    couple’s young daughters—including Joyce Xi—at gunpoint,
    and conducted an extensive search, seizing computers, travel
    records, and financial records. At the conclusion of the search,
    the agents released Qi Li and the daughters, but took Xi to the
    FBI’s Philadelphia field office. There, he was subjected to
    DNA sampling and fingerprinting, before being interrogated
    for approximately two hours. Only then did the agents reveal
    the catalyst for the morning’s events.
    As it turned out, Xi had been indicted on four counts of
    wire fraud for allegedly providing Chinese entities with
    sensitive      information      about     a     “revolution[ary]”
    superconductor technology, known as a “pocket heater”,3 that
    belonged to an American company. See Indictment at ¶ 5,
    United States v. Xi, No. 15-cr-204 (E.D. Pa. May 14, 2015),
    ECF No. 1. Xi had obtained an early version of the pocket
    heater from Shoreline Technologies, a company owned by one
    of its two inventors, in 2004, and then leased the device in 2006
    from its then-owner, Superconductor Technologies, Inc
    (“STI”). As described in the Indictment, Xi purported to
    procure the pocket heater for university research and agreed,
    as a condition of the 2006 lease, that he would not “reproduce,
    3
    A “pocket heater” is described in the Complaint as a
    device for depositing magnesium diboride thin films on flat
    surfaces. Though disputed by Xi, the Indictment charged that
    this device “revolutionized the field of superconducting
    magnesium diboride thin film growth.” See Indictment at ¶ 5,
    United States v. Xi, No. 15-cr-204 (E.D. Pa. May 14, 2015),
    ECF No. 1.
    6
    sell, transfer, or otherwise distribute” the technology “to any
    third party.” Id. at 3. But he then violated the agreement by
    sending four emails related to the device to colleagues in
    China. Id. at 2–4.
    It also turned out that these charges were based on an
    investigation led by Defendant Andrew Haugen, an FBI special
    agent assigned to the agency’s Chinese Counterintelligence
    Unit. In the course of that investigation, as set forth in the
    Complaint, Haugen had interviewed the inventor of the pocket
    heater and learned that Xi’s emails were “not related” to the
    STI pocket heater, but rather to a different process that Xi
    himself had invented.        Nevertheless, according to the
    Complaint, Haugen averred in his affidavits, reports, and other
    communications with prosecutors that those emails did
    concern the pocket heater.
    Eventually, the Prosecutors realized that—just as the
    inventor allegedly told Haugen—Xi’s emails had nothing to do
    with the pocket heater and concerned an “entirely different”
    technology based on Xi’s own research and publications. They
    also learned that the pocket heater was not a “revolutionary”
    device as the Indictment alleged; instead, it was well known
    since 2003 when details of its design were presented at an
    international conference. So the Government moved to
    dismiss the Indictment, acknowledging that “additional
    information came to [its] attention” warranting dismissal.
    Motion to Dismiss Indictment Without Prejudice at ¶ 2, Xi, No.
    15-cr-204 (E.D. Pa. Sept. 11, 2015), ECF No. 29.
    By that time, however, significant damage was already
    done. The U.S. Attorney’s Office had issued a press release
    regarding Xi’s arrest and indictment, and the case had received
    widespread media attention. As a result, Temple suspended Xi
    7
    as Chair of the Physics Department and placed him on
    administrative leave; he was barred from participating in
    research or communicating with his graduate students; and he
    and his family suffered both emotionally and financially.
    After conducting their own investigation into how all
    this transpired, Appellants filed suit in the Eastern District of
    Pennsylvania. See Complaint, Xi v. Haugen, No. 17-cv-2132
    (E.D. Pa. May 10, 2017), ECF No. 1. According to the
    Complaint, the emails on their face revealed that Xi did not
    share any information about the pocket heater with China, and
    the pocket heater was never even referenced in the emails.
    They instead referred to a SINAP tubular heating device
    invented by Xi himself that differs from the pocket heater in
    virtually every respect. The emails were, in short, “normal,
    scientific interactions no different from thousands of similar
    international collaborations among scientists.” App. 82. And
    to the extent any doubt remained as to their contents, the
    Complaint alleged the pocket heater inventor had confirmed
    for Haugen that they were wholly unrelated to that device.
    Based on these allegations, the Complaint asserted two
    groups of claims: (1) Bivens claims, brought by Xi, alleging
    violations of the Fifth Amendment right to equal protection, as
    well as the Fourth Amendment rights to be free from
    unreasonable search and seizure, malicious prosecution, and
    fabrication of evidence, and (2) FTCA claims, brought by all
    Appellants, for Haugen’s alleged torts. 4
    4
    Counts I–III of the Complaint are Bivens claims
    brought by Xi alone for malicious prosecution and fabrication
    of evidence (Count I); denial of equal protection (Count II);
    and unreasonable search and seizure (Count III). Counts IV
    8
    As for the first group of claims, the District Court
    concluded a Bivens remedy was not available, and even if it
    were, Haugen was entitled to qualified immunity because Xi
    failed to establish that his conduct violated any “clearly
    established” constitutional rights. Specifically, the Court held
    that Haugen was immune from Xi’s Fourth Amendment claims
    because the Complaint did not contain sufficient facts to
    support a finding that the Government lacked probable cause
    and there was no “clearly established right to expert validation
    of the technical or scientific evidence that was the basis of a
    probable cause determination in an investigation or
    prosecution.” App. 57. It found no clearly established Fifth
    Amendment violation because while Xi alleged that Haugen
    and VI are FTCA claims brought by Xi alone for malicious
    prosecution (Count IV) and invasion of privacy—false light
    (Count VI). Counts V, VII, and IX are FTCA claims brought
    by Xi, Qi Li, and Joyce Xi for invasion of privacy—intrusion
    upon seclusion (Count V); intentional infliction of emotional
    distress (Count VII); and negligence (Count IX). Count VIII
    is an FTCA claim brought by Qi Li and Joyce Xi for negligent
    infliction of emotional distress.
    After determining that there was no just reason for
    delay, the District Court entered an order certifying its
    judgments on these claims for appeal. Cf. Graber v. Doe, 
    59 F.4th 603
    , 605 (3d Cir. 2023) (recognizing, in the absence of a
    Rule 54(b) certification, that an order denying a motion to
    dismiss a Bivens claim was not a final decision and was not
    appealable under the collateral order doctrine). A tenth claim
    seeking the return and expungement of information and
    property allegedly seized in violation of the Fourth
    Amendment has not been ruled upon by the District Court and
    is therefore not before us.
    9
    predicated his investigation “at least in part on the fact that . . .
    Xi is racially and ethnically Chinese,” he alleged that Haugen
    did so “[a]s a Special Agent employed by the FBI working on
    Chinese counterintelligence,” not because Haugen himself had
    a discriminatory purpose. App. 90.
    The District Court dismissed the second group of
    claims, the FTCA claims, because it concluded they “f[e]ll
    squarely within the [Act’s] discretionary function exception.”
    App. 61. While the Court acknowledged that government
    officials do not possess discretion to violate the Constitution,
    it took the position that the “discretionary function exception”
    precluded suit for all but “clearly established constitutional
    rights.” 
    Id.
     Its determination that Xi failed to establish a
    “clearly established” violation for purposes of its qualified
    immunity analysis was therefore dispositive. 
    Id.
    Xi now brings this timely appeal.
    II.    Jurisdiction and Standard of Review
    The District Court had jurisdiction under 
    28 U.S.C. § 1346
    (b) and 
    28 U.S.C. § 1331
    . We have appellate
    jurisdiction under 
    28 U.S.C. § 1291
    .
    We review a district court’s ruling granting a motion to
    dismiss de novo. Doe v. Univ. of the Scis., 
    961 F.3d 203
    , 208
    (3d Cir. 2020). We accept as true all factual allegations in the
    Complaint and view those facts in the light most favorable to
    the plaintiff. 
    Id.
    III.   Discussion
    We will first address Xi’s Bivens claims and then turn
    to Appellants’ FTCA claims.
    10
    A.     Xi’s Bivens Claims
    To assess Xi’s Bivens claims, we consider, first, the
    Supreme Court’s requirements to pursue a Bivens remedy, and
    second, how those requirements apply to this case. 5
    1. Bivens Framework
    In Bivens, 
    403 U.S. at 388
    , the Supreme Court
    recognized an implied damages remedy for a Fourth
    Amendment violation committed by federal officials whose
    conduct was not encompassed by the statutory remedy
    available against state officials under 
    42 U.S.C. § 1983
    . Bivens
    arose in the unreasonable “search and seizure” context: federal
    narcotics agents forcibly entered and searched Bivens’ home
    without a warrant, then arrested him on federal drug charges
    without probable cause. See 
    403 U.S. at 389
    .
    In the fifty-two years since Bivens was decided,
    however, the Supreme Court has pulled back the reins to what
    appears to be a full stop and no farther. Initially, the Court
    5
    Xi originally asserted his malicious prosecution and
    fabrication of evidence claims under both the Fourth and Fifth
    Amendments, but they implicate only the Fourth Amendment
    because they are founded on allegations that Xi was deprived
    of pretrial liberty without probable cause. See Manuel v. City
    of Joliet, 
    580 U.S. 357
    , 367 (2017) (“If the complaint is that a
    form of legal process resulted in pretrial detention unsupported
    by probable cause, then the right allegedly infringed lies in the
    Fourth Amendment.”); Geness v. Cox, 
    902 F.3d 344
    , 354 n.5
    (3d Cir. 2018) (observing that a claim for reckless investigation
    under the Due Process Clause “could only arise under the
    Fourth Amendment”) (citing Manuel, 580 U.S. at 367).
    11
    extended Bivens to two other contexts: a Fifth Amendment sex-
    discrimination claim brought by a former congressional staffer
    whose Congressman terminated her explicitly because he felt
    it “essential” that her position be held by “a man,” Davis v.
    Passman, 
    442 U.S. 228
    , 230 (1979), and a claim for inadequate
    prison medical care brought under the Eighth Amendment’s
    Cruel and Unusual Punishment Clause, Carlson v. Green, 
    446 U.S. 14
     (1980).
    Since then, however, it has repeatedly refused to extend
    the Bivens remedy to any other amendment, context, or
    category of defendant. Instead, it has clearly communicated
    that Bivens is a “disfavored judicial activity,” Ziglar v. Abbasi,
    
    582 U.S. 120
    , 135 (2017) (internal quotation marks omitted)
    (quoting Iqbal, 
    556 U.S. at 675
    ), impinging on “separation-of-
    powers principles,” id. at 133. Indeed, on no fewer than twelve
    occasions since Bivens, the Court has expressly considered and
    declined to apply a Bivens remedy,6 and we, too, have refused
    6
    See Egbert v. Boule, 
    142 S. Ct. 1793 (2022)
     (First and
    Fourth Amendment suit against Border Patrol agent);
    Hernandez v. Mesa, 
    140 S. Ct. 735 (2020)
     (Fourth and Fifth
    Amendment suit against Border Patrol agent); Minneci v.
    Pollard, 
    565 U.S. 118
     (2012) (Eighth Amendment suit against
    prison guards at a private prison); Hui v. Castaneda, 
    559 U.S. 799
     (2010) (suit under the Fifth, Eighth, and Fourteenth
    Amendments against United States Public Health Service
    personnel); Wilkie v. Robbins, 
    551 U.S. 537
     (2007) (claim of
    retaliation by Bureau of Land Management officials against
    plaintiff for his exercise of Fifth Amendment property rights);
    Corr. Servs. Corp. v. Malesko, 
    534 U.S. 61
     (2001) (Eighth
    Amendment suit against private halfway house operator under
    contract with the Bureau of Prisons); F.D.I.C. v. Meyer, 
    510 U.S. 471
     (1994) (procedural due process suit against federal
    12
    to extend Bivens except in one of these three established
    contexts.7
    Most recently, in Egbert v. Boule, 
    142 S. Ct. 1793 (2022)
    , the Court went so far as to suggest that any extension
    to a new context may be ultra vires. The plaintiff in Egbert
    was a bed-and-breakfast operator and Border Patrol
    confidential informant, who claimed that a Border Patrol agent
    violated his Fourth Amendment rights by using excessive force
    while conducting a search of his property.

    Security officials); United States v. Stanley,

    (1983) (race discrimination suit against military officers).

    27 F.4th 174

    2022) (declining to extend Bivens to Eighth Amendment
    failure-to-protect claim arising in different context than
    Carlson); Bistrian v. Levi, 
    912 F.3d 79
     (3d Cir. 2018)
    (applying a Bivens remedy to Fifth Amendment failure-to-
    protect claim, but not to Fifth Amendment punitive detention
    claim or First Amendment retaliation claim); Davis v. Samuels,

    (3d Cir. 2020) (declining to extend Bivens remedy to First
    Amendment retaliation claim); Vanderklok v. United States,
    
    868 F.3d 189
     (3d Cir. 2017) (same).
    13
    security interests, the Supreme Court’s reasoning bears
    particular significance for this appeal, so we summarize it here.
    At the start, the Court recited its well-established two-
    part test for implying a Bivens remedy: first, we must ask
    “whether the case presents ‘a new [] context’—i.e., is it
    ‘meaningful[ly]’ different from the three cases in which the
    Court has implied a damages action,” id. at 1803 (quoting
    Abbasi, 582 U.S. at 139), and if it is a new context, we ask,
    second, whether “there are ‘special factors’ indicating that the
    Judiciary is at least arguably less equipped than Congress to
    ‘weigh the costs and benefits of allowing a damages action to
    proceed,’” id. (quoting Abbasi, 582 U.S. at 136). But the Court
    observed that these steps “often resolve to a single question:
    whether there is any reason to think that Congress might be
    better equipped to create a damages remedy”; if so, it may not
    expand Bivens to cover the claim. Id.
    As applied to the law enforcement officer in Egbert, an
    agent carrying out U.S. Customs and Border Protection’s
    mandate to “interdic[t] persons attempting to illegally enter or
    exit the United States or goods being illegally imported into or
    exported from the United States” pursuant to 
    6 U.S.C. § 211
    (e)(3)(A), the Supreme Court framed its inquiry as
    “whether a court is competent to authorize a damages action
    not just against Agent Egbert but against Border Patrol agents
    generally.” 
    Id. at 1806
    . And because such an action would
    implicate sensitive matters of foreign policy and national
    security that are “rarely proper subjects for judicial
    intervention,” the Court declined to extend Bivens to the
    plaintiff’s claim, even though it “present[ed] almost parallel
    circumstances to Bivens itself.” 
    Id. at 1805
     (citations omitted).
    Instead, it cautioned: “the Judiciary’s authority” to imply
    14
    additional causes of action under the Constitution “is, at best,
    uncertain.” 
    Id. at 1803
    .
    Guided by Egbert, we now consider whether Xi’s
    claims present a “new context,” and if so, whether special
    factors counsel against allowing a Bivens remedy.
    2. Whether Xi’s Claims Arise in a New
    Context
    Even before Egbert, the Supreme Court had made clear
    that the category of “new contexts” is “broad,” Hernandez v.
    Mesa, 
    140 S. Ct. 735
    , 743 (2020), and this threshold test is
    “easily satisfied,” Abbasi, 582 U.S. at 149. A context may be
    regarded as new if it is different in any “meaningful way” from
    the three contexts where the Court has recognized a Bivens
    remedy, id. at 139, and even “a modest extension is still an
    extension,” id. at 147. Below, we apply this test to Xi’s Fourth
    Amendment and Fifth Amendment claims.
    i. Fourth Amendment Claims
    Xi points to factual parallels with Bivens, where federal
    narcotics agents forcibly entered and searched the plaintiff’s
    home without a warrant, handcuffed and arrested him in front
    of his wife and children, and subjected him to a strip search.
    
    403 U.S. at 389
    . But Egbert tells us that “almost parallel
    circumstances” are not enough, and here, distinctions abound.
    142 S. Ct. at 1805.
    For one, Xi’s claims concern a different breed of law
    enforcement misconduct. While Bivens involved a claim
    against federal agents for an illegal arrest and warrantless
    search, see 
    403 U.S. at 389
    , Xi alleges that federal agents made
    15
    false statements and material omissions of exculpatory
    evidence that led the Government to investigate, arrest, and
    prosecute him. Such “case-building activities are a different
    part of police work than the apprehension, detention, and
    physical searches at issue in Bivens.” Farah v. Weyker, 
    926 F.3d 492
    , 499 (8th Cir. 2019). And under Egbert, that
    difference is material because it provides a “potential” reason
    to think that judicial intrusion in this context would be harmful
    or inappropriate. 142 S. Ct. at 1805. Specifically, evaluating
    Xi’s claims would “invite a wide-ranging inquiry” into the
    agent’s state of mind and “the evidence available to
    investigators, prosecutors, and the grand jury.” Farah, 
    926 F.3d at 500
    .
    Another distinction is that Xi seeks to hold accountable
    a “new category of defendant[]”: a federal counterintelligence
    agent. Egbert, 142 S. Ct. at 1803 (citations omitted). We have
    considered the significance of this distinction before in
    Vanderklok v. United States, 
    868 F.3d 189
     (3d Cir. 2017).
    There, we analyzed “whether a First Amendment claim against
    a TSA employee for retaliatory prosecution . . . exists in the
    context of airport security screenings.” 
    Id. at 194
    . In
    concluding it does not, we observed that “TSA employees . . .
    are tasked with assisting in a critical aspect of national
    security—securing our nation’s airports and air traffic.” 
    Id. at 207
    . The same is true here because counterintelligence agents
    like Haugen protect the nation from threats of foreign
    espionage.
    Nor does it matter that Haugen is a “line-level” agent,
    like the officers in Bivens, rather than a “high-ranking or
    supervisory official.” Opening Br. 45. While the “rank of the
    officers involved” is one way in which a case “might” differ
    from Bivens, it is hardly dispositive. Abbasi, 582 U.S. at 139–
    16
    40. Indeed, the claim in Egbert was likewise against a rank-
    and-file officer, yet the Court concluded that other factual
    distinctions—most notably, the national security interests—
    rendered the context “new.” 142 S. Ct. at 1804–07; see also
    Hernandez, 
    140 S. Ct. at 743
     (concluding that although the
    claim involved a rank-and-file border patrol agent, it was
    “glaringly obvious” that his use of force in a cross-border
    shooting presented a new context).
    In short, the differences between Bivens and this case
    make clear that Xi’s Fourth Amendment claims arise in a
    context the Supreme Court has not previously countenanced.
    ii. Fifth Amendment Claim
    The context of Xi’s Fifth Amendment claim is even
    further afield. Xi contends that he was denied Equal Protection
    because he was investigated by “a Special Agent employed by
    the FBI working on Chinese counterintelligence” based “on the
    fact that . . . Xi is racially and ethnically Chinese.” Thus,
    Davis, 
    442 U.S. 228
    , provides the closest analog, but even at a
    high level, the cases are materially different.
    Whereas Davis involved a claim of federal workplace
    sex discrimination brought by a congressional staffer, 
    id. at 230
    , here, the claim is racial discrimination brought by the
    target of a federal counterintelligence investigation. These
    distinctions, on their own, establish “a[] new context [and]
    category of defendant[].” Abbasi, 582 U.S. at 135 (quotation
    marks omitted); see also Tun-Cos v. Perrotte, 
    922 F.3d 514
    ,
    525 (4th Cir. 2019) (holding that Plaintiffs’ claims that ICE
    agents discriminated against them on the basis of their Latino
    ethnicity while enforcing the INA had “no analogue” in the
    Supreme Court’s prior Bivens cases).
    17
    In addition, the plaintiff’s injury in Davis resulted
    directly from the individual discriminatory attitude and actions
    of her Congressman-employer. Xi, on the other hand, does not
    allege that Haugen harbored personal animus against the
    Chinese. Rather, to the extent Xi alleges that Haugen’s
    investigation was “predicated at least in part on the fact that
    [he] is racially and ethnically Chinese,” App. 90, he attributes
    it solely to the FBI’s counterintelligence policy and the mission
    of its Chinese counterintelligence unit.
    The conduct that Xi challenges is also of a far broader
    scope than the discrete action in Davis. The plaintiff there
    challenged a specific employment decision: her termination
    based on the view it was “essential” for a man to be hired. 
    442 U.S. at 230
    . Cf. Strickland v. United States, 
    32 F.4th 311
    , 372–
    74 (4th Cir. 2022) (concluding that Plaintiff’s sex-
    discrimination claim, brought under a retaliation theory, arose
    in a new Bivens context for this reason).8 Xi, in contrast,
    contests “Haugen’s investigation and initiation of
    prosecution . . . based on impermissible racial and ethnic
    factors” that Xi believes informed the FBI’s investigative
    priorities and charging recommendation. App. 98.
    8
    Xi attempts to circumvent these distinctions by
    arguing that his claim shares Davis’s “central feature” of
    intentional discrimination based on membership in a protected
    class and Bivens’s setting of a search and seizure. Reply Br.
    21. But neither the Supreme Court nor this Court has adopted
    this piecemeal approach, and we decline to do so now. Cf.
    Perrotte, 
    922 F.3d at 525
     (rejecting Plaintiffs’ analogous
    efforts to “wed the Fifth Amendment equal protection claim of
    Davis . . . with the Fourth Amendment claim of Bivens”).
    18
    In short, Xi’s Fifth Amendment claim—like his Fourth
    Amendment claims—presents a new context that requires us to
    advance to the next step: whether special factors preclude a
    Bivens extension.
    3. Special Factors Counseling Against
    Extending Bivens
    Because we are confronting claims in new contexts, we
    proceed to consider at step two whether “special factors
    counsel[] hesitation” in extending a Bivens remedy. Abbasi,
    582 U.S. at 136 (quotation marks omitted). At this step, the
    existence of “even a single reason to pause before applying
    Bivens” forecloses relief, Egbert, 142 S. Ct. at 1803 (quotation
    marks and citation omitted), because “in all but the most
    unusual circumstances, prescribing a cause of action is a job
    for Congress, not the courts,” id. at 1800. Such is the case here,
    where one overriding special factor counsels against the
    creation of a judicially-implied Bivens remedy: the implication
    of national security interests.
    In arguing that malicious prosecution and other law
    enforcement misconduct claims are “standard and well
    recognized,” Xi’s focus is misplaced. Opening Br. 50. Xi is
    seeking relief against a federal counterintelligence official for
    alleged misconduct during an investigation into potential
    espionage. While malicious prosecution and civil rights claims
    may commonly follow the dismissal of charges, Egbert
    instructs us to concentrate not on the substance of a particular
    claim, but on the context in which it is brought. Put differently,
    the question is not “whether Bivens relief is appropriate in light
    of the balance of circumstances in the particular case,” but
    whether “[m]ore broadly . . . there is any reason to think that
    judicial intrusion into a given field might be harmful or
    19
    inappropriate.” Egbert, 142 S. Ct. at 1805 (quotation marks
    and citation omitted). And we see three reasons to think that
    judicial intrusion would be both harmful and inappropriate in
    the context of a case like Xi’s, with “unquestionabl[e] national
    security implications.” Id. at 1804 (citation omitted).
    First, as a practical matter, counterintelligence officials,
    like Border Patrol agents, are on the front lines of responding
    to national security threats where the prospect of damages
    liability could cause them to “second-guess difficult but
    necessary decisions” with significant consequences for public
    safety and foreign policy. Abbasi, 582 U.S. at 142; see also
    Vanderklok, 
    868 F.3d at 207
     (concluding that “[t]he threat of
    damages liability could indeed increase the probability that a
    TSA agent would hesitate in making split-second decisions
    about suspicious passengers”). In addition, the resolution of
    such claims might well require judicial review of executive
    counterintelligence policies and priorities—even in cases, like
    Xi’s, where the plaintiff sues not the agency’s policy makers,
    but rather those “employed by the [agency]” to implement its
    directives. App. 90.
    Second, implying a Bivens remedy is a “significant step
    under separation-of-powers principles,” Abbasi, 582 U.S. at
    133, and an overstep when it comes to “[m]atters intimately
    related to foreign policy and national security,” Egbert, 142 S.
    Ct. at 1804–05 (quoting Haig v. Agee, 
    453 U.S. 280
    , 292
    (1981)). Those matters are “committed to the other branches,”
    and courts are comparatively ill-suited to weigh the
    consequences of personal damages liability on our national
    security apparatus. Abbasi, 582 U.S. at 142 (citation omitted).
    Xi counters that this should not count as a special factor
    because he did not, in fact, pose a national security threat. But
    20
    as the Supreme Court explained in Hernandez, that argument
    “misses the point.” 
    140 S. Ct. at 746
    . Whether Haugen had a
    bona fide national security justification for his investigation of
    Xi is no more relevant to this inquiry than whether the “federal
    agent supposedly did not act pursuant to his law-enforcement
    mission” in Egbert, 142 S. Ct. at 1808, or whether the cross-
    border shooting of the Mexican national was actually justified
    by national security in Hernandez, 
    140 S. Ct. at 746
    . As the
    Court has explained, the question in such cases “is not whether
    national security requires such conduct—of course, it does
    not,” but rather, “whether the Judiciary should alter the
    framework established by the political branches for
    addressing” that conduct. 
    Id.
    The third counterweight to a Bivens action here is the
    availability of alternative remedies. An alternative remedy “is
    reason enough to limit the power of the Judiciary to infer a new
    Bivens cause of action.” Egbert, 142 S. Ct. at 1804 (quotation
    marks and citation omitted). And Congress allowed two such
    remedies in this context: 
    28 U.S.C. § 1495
     and the Hyde
    Amendment, 18 U.S.C. § 3006A. The former permits an
    award of damages to “any person unjustly convicted of an
    offense against the United States and imprisoned.” 
    28 U.S.C. § 1495
    . The latter allows courts to award attorney’s fees and
    litigation costs to a prevailing criminal defendant “when the
    court finds that the position of the United States was vexatious,
    frivolous, or in bad faith.” 
    Pub. L. No. 105-119,
     tit. VI, § 617,
    
    111 Stat. 2440
    , 2519 (1997) (codified at 18 U.S.C. § 3006A
    note).
    Understandably, Xi is not satisfied with these
    alternatives—presumably because he was never convicted and
    can only be made whole by monetary damages. But Egbert
    instructs that an alternative remedy need not provide “complete
    21
    relief” or be as “effective as an individual damages remedy” to
    foreclose Bivens relief. 142 S. Ct. at 1804, 1807 (quotation
    marks and citations omitted). In fact, the focus is not on the
    individual’s recovery at all. It is on deterrence, and we must
    respect its decision when “Congress or the Executive has
    created a remedial process that it finds sufficient to secure an
    adequate level of deterrence.” Id. at 1807. Congress created
    such a remedial process for the kinds of claims brought by Xi
    and found sufficient deterrence in providing a remedy to one
    class of plaintiff—i.e., convicted defendants—and not to
    another—i.e., those whose indictments were dismissed. As a
    result, we will not “second-guess that calibration by
    superimposing a Bivens remedy.” Id.
    ***
    Having found that Xi’s Fourth and Fifth Amendment
    claims arise in a new context and implicate special factors
    counseling against a Bivens remedy, we will affirm the District
    Court’s dismissal of Xi’s Bivens claims.9
    B.     Xi, Qi Li, and Joyce Xi’s Claims Under the
    Federal Tort Claims Act
    That leaves us with Xi and his family’s FTCA claims.
    The FTCA waives the federal government’s sovereign
    immunity for the negligent actions of its employees. See
    Berkovitz v. United States, 
    486 U.S. 531
    , 535 (1988); 
    28 U.S.C. §§ 2671
    –2680. That waiver, however, is subject to certain
    exceptions, including the discretionary function exception, at
    9
    Having so concluded, we need not decide whether Xi’s
    Fourth and Fifth Amendment claims are also barred by
    qualified immunity.
    22
    issue in this case. This exception effectively retains the
    Government’s immunity for “[a]ny claim . . . based upon the
    exercise or performance or the failure to exercise or perform a
    discretionary function or duty . . . whether or not the discretion
    involved be abused.” 
    28 U.S.C. § 2680
    (a). As a result, a claim
    concerning conduct that falls within this exception must be
    dismissed for lack of subject matter jurisdiction. Berkovitz,
    
    486 U.S. at 533
    .
    The Supreme Court has enunciated a two-part test for
    determining if the discretionary function exception applies.
    First, we consider the nature of the conduct and decide whether
    it “involv[es] an element of judgment or choice.” United States
    v. Gaubert, 
    499 U.S. 315
    , 322 (1991) (citation omitted).
    Where it does not involve judgment or choice—such as where
    “a ‘federal statute, regulation, or policy specifically prescribes
    a course of action for an employee to follow’”—the inquiry is
    at an end and the exception is inapplicable because the conduct
    is not discretionary; “the employee has no rightful option but
    to adhere to the directive.” 
    Id.
     (citation omitted). But where
    the employee does have a choice, we consider, at step two
    “whether that judgment is of the kind that the . . . exception
    was designed to shield.” 
    Id.
     at 322–23 (quotation marks
    omitted).
    Essential for today’s purposes, we—and nearly every
    circuit to have considered the issue—have held that “conduct
    cannot be discretionary if it violates the Constitution” because
    “[f]ederal officials do not possess discretion to violate
    constitutional rights.” U.S. Fid. & Guar. Co. v. United States,
    23
    
    837 F.2d 116
    , 120 (3d Cir. 1988) (citation omitted).10 And that
    is where we take issue with the District Court’s reasoning.
    10
    See Nieves Martinez v. United States, 
    997 F.3d 867
    ,
    877 (9th Cir. 2021) (“Even if the agents’ actions involved
    elements of discretion, agents do not have discretion to violate
    the Constitution.”); Loumiet v. United States, 
    828 F.3d 935
    ,
    943 (D.C. Cir. 2016) (“[T]he FTCA’s discretionary-function
    exception does not provide a blanket immunity against tortious
    conduct that a plaintiff plausibly alleges also flouts a
    constitutional prescription.”); Limone v. United States, 
    579 F.3d 79
    , 101 (1st Cir. 2009) (“It is elementary that the
    discretionary function exception does not immunize the
    government from liability for actions proscribed by federal
    statute or regulation. . . . Nor does it shield conduct that
    transgresses the Constitution.”); Raz v. United States, 
    343 F.3d 945
    , 948 (8th Cir. 2003) (“We must also conclude that the
    FBI’s alleged surveillance activities fall outside the FTCA’s
    discretionary-function exception because Raz alleged they
    were conducted in violation of his First and Fourth
    Amendment rights.”); Medina v. United States, 
    259 F.3d 220
    ,
    225 (4th Cir. 2001) (quotation marks and citations omitted)
    (“[W]e begin with the principle that federal officials do not
    possess discretion to violate constitutional rights or federal
    statutes.”); Myers & Myers, Inc. v. USPS, 
    527 F.2d 1252
    , 1261
    (2d Cir. 1975) (citations omitted) (“It is, of course, a tautology
    that a federal official cannot have discretion to behave
    unconstitutionally or outside the scope of his delegated
    authority.”); but see Shivers v. United States, 
    1 F.4th 924
     (11th
    Cir. 2021); Linder v. United States, 
    937 F.3d 1087
     (7th Cir.
    2019).
    24
    The District Court acknowledged that officials lack
    discretion to violate the Constitution, but it seems to have
    assumed, nonetheless, that the discretionary function exception
    immunized all but “clearly established” constitutional
    violations. After observing that judgments about whether and
    how to investigate a suspect are generally discretionary, the
    District Court harkened back to its alternative ground for
    dismissing Xi’s Bivens claims—that Haugen also would be
    entitled to qualified immunity because any constitutional rights
    he violated were not “clearly established.” On that basis, and
    without further discussion, the District Court held Xi’s FTCA
    claims “fall squarely within the discretionary function
    exception.” App. 61.
    Below we consider (1) whether the discretionary
    function exception excludes all constitutional violations or
    only violations that are “clearly established,” and (2) whether
    the allegations in Xi’s Complaint were sufficient to state a
    constitutional claim.
    1. The District Court’s “Clearly Established”
    Requirement
    In finding dispositive that Haugen’s conduct, even if
    unconstitutional, did not violate “clearly established” rights,
    the District Court imported a requirement for qualified
    immunity into the discretionary function analysis. See App. 49
    (citing Harlow v. Fitzgerald, 
    457 U.S. 800
    , 818 (1982)) (other
    citations omitted). As we clarify today, however, that “clearly
    established” requirement has no place there, where it is
    unmoored from both precedent and purpose.
    As for precedent, over thirty years of binding circuit
    precedent holds that the discretionary exception does not apply
    25
    to conduct that violates the Constitution regardless of whether
    the constitutional rights at issue were “clearly established.”
    See, e.g., U.S. Fid. & Guar. Co., 
    837 F.2d at 120
     (“[C]onduct
    cannot be discretionary if it violates the Constitution, a statute,
    or an applicable regulation. . . .”); Pooler v. United States, 
    787 F.2d 868
    , 871 (3d Cir. 1986), abrogated on other grounds by
    Millbrook v. United States, 
    569 U.S. 50
    , 57 (2013) (“[I]f the
    complaint were that agents of the government in the course of
    an investigation had violated constitutional rights or federal
    statutes, the outcome would be different since federal officials
    do not possess discretion to commit such violations.”).11 The
    reason is simple: because government officials never have
    discretion to violate the Constitution, unconstitutional
    11
    Defendants’ argument that our ruling in Bryan v.
    United States, 
    913 F.3d 356
     (3d Cir. 2019), broke this line of
    precedent is unpersuasive. There, the plaintiffs argued that
    certain border searches were impermissible under United
    States v. Whitted, 
    541 F.3d 480
     (3d Cir. 2008)—a decision
    issued the day before the searches occurred. We held that the
    officers were entitled to qualified immunity because they could
    not reasonably have been informed about Whitted, and
    resolved Plaintiffs’ FTCA claims in a single sentence stating
    “the CBP officers did not violate clearly established
    constitutional rights, [so] the FTCA claims also fail.” Bryan,
    
    913 F.3d at 364
    . We did so without briefing, analysis, or
    discussion of the issue. We did not adopt a new test for the
    discretionary exception or qualify the reach of our prior
    precedent—which did not impose a clearly established
    requirement. See Holland v. N.J. Dep’t of Corr., 
    246 F.3d 267
    ,
    278 n.8 (3d Cir. 2001) (“[T]o the extent that [a case within the
    circuit] is read to be inconsistent with earlier case law, the
    earlier case law . . . controls.”).
    26
    government conduct is per se outside the discretionary function
    exception.12
    Nor, in the discretionary function context, would such a
    requirement serve a purpose. The Supreme Court excluded
    clearly established constitutional violations from the
    protections of qualified immunity because it would be unfair
    to hold individual officers liable for “conduct not previously
    identified as unlawful,” Harlow, 
    457 U.S. at 818
    , and the Court
    was mindful of the chilling effect and “social costs” of that
    liability. 
    Id.
     at 813–15. But these concerns are absent in the
    FTCA context, where only the federal government—not
    individual officers—can be liable. See 
    28 U.S.C. § 2674
    ; see
    also Owen v. City of Independence, 
    445 U.S. 622
    , 655–56
    (1980) (holding that government entities are not entitled to
    qualified immunity and justifying qualified immunity for
    individual officers based on “the concern that the threat of
    personal monetary liability will introduce an unwarranted . . .
    consideration into the decisionmaking process . . . .”).
    Thus, the District Court erred in dismissing Xi’s FTCA
    claims on the ground that Xi failed to demonstrate a violation
    of “clearly established” constitutional rights. At the motion-
    to-dismiss stage, all a plaintiff must do to negate the
    discretionary function exception is plausibly allege a
    12
    While every action that violates a clearly established
    constitutional right violates the Constitution, the converse is
    not true. See, e.g., Pearson v. Callahan, 
    555 U.S. 223
    , 236
    (2009) (acknowledging it is “often beneficial” to break up
    these inquiries).
    27
    constitutional violation. We consider, then, whether Xi has
    done so here.
    2. Whether Xi Has Plausibly Alleged a
    Constitutional Violation
    To determine whether Xi has plausibly alleged a
    constitutional violation, we accept the facts alleged in the
    Complaint as true and draw all inferences in Xi’s favor. Rivera
    v. Monko, 
    37 F.4th 909
    , 914 (3d Cir. 2022). For the reasons
    set forth below, we conclude that the District Court correctly
    dismissed Xi’s Fifth Amendment claim but erred in holding he
    failed to state a Fourth Amendment claim.
    i. Xi’s Fifth Amendment Claim
    To state a Fifth Amendment claim for selective
    enforcement, a plaintiff must demonstrate that the defendant
    targeted him “not for a neutral, investigative reason but for the
    purpose of discriminating on account of race, religion, or
    national origin.” Iqbal, 
    556 U.S. at 677
    . “[B]are assertions”
    that the defendant acted with discriminatory purpose will not
    suffice. 
    Id. at 681
    . The plaintiff must set forth “sufficient
    factual matter” to show that the defendant acted “‘because of,’
    not merely ‘in spite of’” a protected characteristic. 
    Id. at 677, 681
     (citation omitted); see also Jewish Home of E. Pa. v. Ctrs.
    for Medicare and Medicaid Servs., 
    693 F.3d 359
    , 363 (3d Cir.
    2012) (citation omitted) (to maintain selective enforcement
    claim, plaintiff must provide “evidence of discriminatory
    purpose, not mere unequal treatment or adverse effect”); PG
    Publ’g Co. v. Aichele, 
    705 F.3d 91
    , 115 (3d Cir. 2013)
    (concluding plaintiffs failed to allege equal protection claim
    where allegations showed “no sign of ‘clear and intentional
    28
    discrimination’” (quoting Snowden v. Hughes, 
    321 U.S. 1
    , 8
    (1944))).
    Here, the Complaint’s allegations of discriminatory
    purpose are wholly conclusory and the circumstantial evidence
    to which Xi points does not support an inference of
    discrimination. The only direct allegations of discriminatory
    intent are that Haugen’s “investigation . . . was predicated at
    least in part on the fact that Professor Xi is racially and
    ethnically Chinese,” App. 90, and that Haugen “considered
    Professor Xi’s race and ethnicity in providing false
    information” with the “intent to secure false charges,” App. 91.
    But such “conclusory . . . allegations” are “not entitled to be
    assumed true.” Iqbal, 
    556 U.S. at 681
     (citations omitted). Xi
    also posits that the government had dismissed the indictments
    of three other Chinese-American scientists prior to trial, but the
    Complaint does not allege that Haugen had any involvement in
    those indictments, let alone explain the basis for their
    dismissal, so it sheds no light on the intent of the particular
    agent in this particular case.
    We may not fill this gap in Xi’s pleading with
    speculation. Xi posits that because “there was no factual basis”
    to indict him, “what motivated Haugen to ignore the lack of
    probable cause and falsify information” must have been racial
    or ethnic bias. Reply Br. 8. But there also may be non-
    discriminatory explanations for Haugen’s investigation, and
    the possibility of a discriminatory motive is insufficient.
    Where, as here, the allegations are merely consistent with
    liability, the claim “stops short of the line between possibility
    and plausibility of entitlement to relief,” Iqbal, 
    556 U.S. at 678
    (quotation marks and citation omitted), so Xi’s Fifth
    Amendment claim was properly dismissed.
    29
    ii. Xi’s Fourth Amendment Claims
    Xi fares better with his Fourth Amendment claims,
    however. Those claims—brought under the rubrics of
    malicious prosecution, fabrication of evidence, and
    unreasonable search and seizure—all turn on whether the
    Government investigated, searched, and prosecuted him
    without probable cause. Because a grand jury indictment
    “constitutes prima facie evidence of probable cause to
    prosecute,” Rose v. Bartle, 
    871 F.2d 331
    , 353 (3d Cir. 1989),
    and the search and seizure here were conducted pursuant to
    duly authorized warrants, we begin with the presumption that
    Haugen acted with probable cause, see United States v. Yusuf,
    
    461 F.3d 374
    , 383 (3d Cir. 2006). But that presumption may
    be rebutted by a plausible allegation that the indictment was
    “procured by fraud, perjury or other corrupt means,” Rose, 
    871 F.2d at 353
     (citations omitted), or that Haugen “knowingly and
    deliberately, or with a reckless disregard for the truth, made
    [materially] false statements or omissions” in the warrant
    application, Sherwood v. Mulvihill, 
    113 F.3d 396
    , 399 (3d Cir.
    1997).
    Xi has met that pleading standard here because the
    Complaint alleged at least seven discrete instances of Haugen
    intentionally, knowingly, and/or recklessly providing false
    information that led to Xi’s prosecution. It alleged, for
    example, that before charges were filed, the inventor of the
    pocket heater informed Haugen that the emails in question
    described an “entirely different” device from the pocket
    heater—one that Xi himself had invented, App. 83; and that the
    pocket heater technology was not “revolutionary,” but “widely
    known,” App. 84. It also alleged that Haugen accused Xi of
    “a scheme to obtain the pocket heater technology” at a point in
    time when, as Haugen knew or recklessly disregarded, that
    30
    technology did not yet exist, 
    id.,
     and that Haugen knew or
    recklessly disregarded that Xi never sent samples or test results
    from the pocket heater to colleagues in China, but only
    engaged with them in normal academic collaboration. Such
    detailed allegations are hardly the “naked assertion[s] devoid
    of further factual enhancement” that would justify dismissal.
    George v. Rehiel, 
    738 F.3d 562
    , 581 (3d Cir. 2013) (quotation
    marks and citation omitted).
    In concluding otherwise, the District Court reasoned
    that the allegations were inadequate because Haugen may not
    have become aware of these falsehoods until after he conveyed
    them to prosecutors, and after the indictment was returned.
    But at this stage, we are required to accept plaintiff’s
    allegations as true and draw all inferences in his favor, see
    Univ. of the Scis., 961 F.3d at 208; and here, Xi has explicitly
    alleged that Haugen knew or recklessly disregarded evidence
    of Xi’s innocence even “[b]efore the Indictment was sought
    and returned.” App. 73. In other words, Xi has rebutted the
    presumption of probable cause and plausibly alleged a Fourth
    Amendment violation. So the discretionary function exception
    provides no bar to the pursuit of his FTCA claims premised on
    the same conduct.
    IV.    Conclusion
    For the foregoing reasons, we will affirm the District
    Court’s dismissal of Xi’s Bivens claims, reverse its dismissal
    of Appellants’ FTCA claims, and remand for further
    proceedings in accordance with this opinion.13
    13
    Given the narrow issues before us, we have no
    occasion to reach other questions that may be raised before the
    31
    District Court, and that may provide alternative bases for
    dismissal.

    I join the Court’s opinion in full. I write separately only to
    flag that it might be time for the Supreme Court to revisit the
    test for when the FTCA’s discretionary-function exception ap-
    plies. The Court last addressed this test more than thirty years
    ago. See United States v. Gaubert, 
    499 U.S. 315
     (1991). Before
    that, courts were having “difficulty in applying [it].” 
    Id. at 335
    (Scalia, J., concurring). So Gaubert sought to clarify things.
    See 
    id.
     at 322–25 (majority opinion).
    But courts are still struggling. See, e.g., 14 Charles Alan
    Wright, Arthur R. Miller & Helen Hershkoff, Federal Practice
    & Procedure § 3658.1 (4th ed. 2023) (noting that the “exact
    boundaries of the exception remain unclear, despite an im-
    mense amount of precedent”). Similar facts have led to oppo-
    site conclusions. To give just a few examples, courts have dis-
    agreed about whether the discretionary-function exception co-
    vers the following conduct:
    •   The government’s failure to maintain a road. Compare
    Walters v. United States, 
    474 F.3d 1137
    , 1140 (8th Cir.
    2007) (exception applies), Mitchell v. United States,
    
    225 F.3d 361
    , 366 (3d Cir. 2000) (same), and Baum v.
    United States, 
    986 F.2d 716
    , 722, 724 (4th Cir. 1993)
    (same), with Bolt v. United States, 
    509 F.3d 1028
    ,
    1033–35 (9th Cir. 2007) (exception does not apply),
    Williams v. United States, 
    2018 WL 3655901
    , at *6 (D.
    Md. Aug. 2, 2018) (same), and Quigley v. United States,
    
    927 F. Supp. 2d 213
    , 224 (D. Md. 2012) (same).
    •   The government’s failure to post warning signs on fed-
    eral property. Compare Rosebush v. United States, 119
    
    1 F.3d 438
    , 444 (6th Cir. 1997) (exception applies), and
    Valdez v. United States, 
    56 F.3d 1177
    , 1180 (9th Cir.
    1995) (same), with Duke v. Dep’t of Agric., 
    131 F.3d 1407
    , 1412 (10th Cir. 1997) (exception does not apply),
    and Parrish v. United States, 
    157 F. Supp. 3d 434
    , 447
    (E.D.N.C. 2016) (same).
    •   The government’s management of tree hazards. Com-
    pare Merando v. United States, 
    517 F.3d 160
    , 174 (3d
    Cir. 2008) (exception applies), and Autery v. United
    States, 
    992 F.2d 1523
    , 1531 (11th Cir. 1993) (same),
    with Walen v. United States, 
    246 F. Supp. 3d 449
    , 466
    (D.D.C. 2017) (exception does not apply).
    •   The government’s failure to provide clean water at
    Camp Lejeune. Compare In re Camp Lejeune N.C. Wa-
    ter Contamination Litig., 
    263 F. Supp. 3d 1318
    , 1356–
    57 (N.D. Ga. 2016) (exception applies), aff’d, 
    774 F. App’x 564
     (11th Cir. 2019), Snyder v. United States,
    
    504 F. Supp. 2d 136
    , 141 (S.D. Miss. 2007) (same),
    aff’d, 
    296 F. App’x 399
     (5th Cir. 2008), and Tate v.
    Camp Lejeune, 
    2019 WL 7373699
    , at *2 (E.D.N.C.
    Dec. 30, 2019) (same), with Pride v. Murray, 
    595 F. Supp. 3d 453
    , 463 (W.D.N.C. 2022) (exception does not
    apply), and Washington v. Dep’t of the Navy, 
    446 F. Supp. 3d 20
    , 29 (E.D.N.C. 2020) (same).
    Though case-specific differences may partly explain these dis-
    agreements, there is also significant confusion about how to
    apply the test. Compare, e.g., Merando, 
    517 F.3d at
    172–75
    (finding that tree management involves policy judgment), with
    2
    Walen, 
    246 F. Supp. 3d at
    465–66 (finding that tree manage-
    ment involves professional rather than policy judgment).
    And there are at least three longstanding, recurring circuit
    splits involving the discretionary-function exception:
    •   First, there is the split we weigh in on today: whether
    unconstitutional conduct necessarily falls outside the
    exception. See Maj. Op. 24 n.10.
    •   Second, there is a split over whether the exception ap-
    plies when the challenged act was careless rather than a
    considered exercise of discretion. Compare Willis v.
    Boyd, 
    993 F.3d 545
    , 549 (8th Cir. 2021) (carelessness
    covered by exception), Lam v. United States, 
    979 F.3d 665
    , 682 (9th Cir. 2020) (same), and Ball v. United
    States, 
    967 F.3d 1072
    , 1077 (10th Cir. 2020) (same),
    with Coulthurst v. United States, 
    214 F.3d 106
    , 111 (2d
    Cir. 2000) (carelessness outside exception), Rich v.
    United States, 
    811 F.3d 140
    , 147 (4th Cir. 2015) (same),
    and Palay v. United States, 
    349 F.3d 418
    , 432 (7th Cir.
    2003) (same).
    •   Finally, there is a split over whether claims that fall
    within the FTCA’s law-enforcement proviso must also
    fall outside the discretionary-function exception. Com-
    pare Nguyen v. United States, 
    556 F.3d 1244
    , 1260
    (11th Cir. 2009) (proviso trumps exception), with Joiner
    v. United States, 
    955 F.3d 399
    , 406 (5th Cir. 2020) (pro-
    viso “does not automatically trump” exception), Linder
    v. United States, 
    937 F.3d 1087
    , 1089 (7th Cir. 2019)
    (same), Medina v. United States, 
    259 F.3d 220
    , 224–26
    (4th Cir. 2001) (same), Gasho v. United States, 
    39 F.3d 3
    1420, 1433 (9th Cir. 1994), and Gray v. Bell, 
    712 F.2d 490
    , 507–08 (D.C. Cir. 1983) (same).
    This longstanding confusion shows the need for more guidance
    on how to apply the exception.
    The current test also seems divorced from the exception’s
    text. The test asks whether the challenged “action” involved
    the “permissible exercise of policy judgment.” Berkovitz v.
    United States, 
    486 U.S. 531
    , 536–37 (1988). But the text
    speaks of a discretionary “function or duty.” 
    28 U.S.C. § 2680
    (a). Compare 
    id.,
     with 
    id.
     § 2680(e) (referencing an “act
    or omission”). These words suggest that courts should look at
    the kind of activity the officer was performing when the chal-
    lenged action occurred, not the action itself.
    This higher-level approach is confirmed by the ordinary le-
    gal meaning of the phrase “discretionary function” when the
    FTCA was enacted. The phrase was used to describe a public
    officer’s immunity when sued for torts in his personal capacity.
    See William L. Prosser, Handbook of the Law of Torts § 108,
    at 1075–79 (1941 ed.). Courts categorized certain kinds of gov-
    ernment activities as either “ministerial” or “discretionary.” Id.
    For example, the “care of prisoners” and “driving of vehicles”
    were ministerial. Id. at 1077. So a public officer could be held
    liable for any negligence or wrongdoing in their performance.
    Id. Other activities, like the “routing of a highway” or “assess-
    ment of property for taxation,” were discretionary. Id. at 1076.
    So an officer was immune from suit even if he did those activ-
    ities negligently. Id.
    This approach is not only more consistent with the text, but
    can be applied earlier in a suit. The current test is fact- and
    4
    time-intensive. Courts must comb through and interpret federal
    regulations and policies, looking for anything that forbids the
    challenged conduct. See, e.g., S.R.P. ex rel. Abunabba v.
    United States, 
    676 F.3d 329
    , 334–36 (3d Cir. 2012) (reviewing
    various National Park Service policies). Sometimes, plaintiffs
    need discovery. See Berkovitz, 
    486 U.S. at
    547–48. These bur-
    dens are particularly concerning because the application of the
    exception goes to whether the United States has waived its sov-
    ereign immunity; thus, the government must go through a
    mini-trial just to figure out whether it is in fact immune from
    suit. By contrast, the relevant category of officer activity
    should be apparent from the face of the complaint. And for
    guidance on how to categorize an activity, courts can look to
    how that activity (or an analogous one) was categorized in suits
    against public officials when the FTCA was enacted.
    * * * * *
    With Bivens sharply limited, the stakes of clarifying the
    scope of the discretionary-function exception grow ever
    greater. Plaintiffs like Xi must increasingly rely on the FTCA
    to vindicate their constitutional rights. They, the government,
    and the courts would all benefit from clearer guidance.
