    ORDER AND JUDGMENT*

    Before HARTZ, MATHESON, and CARSON, Circuit Judges.
    _________________________________
    Plaintiff-Appellant Anthony Martinez sued the United States under the Federal
    Tort Claims Act (“FTCA”) after a police officer shot him. He alleged three Southern Ute
    Police Department (“SUPD”) officers—Cheryl Herrera, Matthew Mitchell, and Patrick
    Backer (the “Officers”)—negligently intruded onto his property late at night without
    *
    This order and judgment is not binding precedent, except under the doctrines of
    law of the case, res judicata, and collateral estoppel. It may be cited, however, for its
    persuasive value consistent with Fed. R. App. P. 32.1 and 10th Cir. R. 32.1.
    identifying themselves.1 The district court held a bench trial and found for the United
    States. Mr. Martinez appealed, challenging the district court’s negligence analysis.
    After oral argument, we ordered the parties to submit supplemental briefs to
    address whether the district court lacked subject matter jurisdiction under the FTCA
    because the United States retained sovereign immunity under the discretionary function
    exception. See 28 U.S.C. § 2680(a).2
    1
    The Indian Self-Determination and Education Assistance Act (“ISDEA”) allows
    the United States to contract with Native American tribes to provide law enforcement
    funding. Under such contracts, “an Indian tribe . . . and its employees are deemed
    employees of the [United States] while acting within the scope of their employment in
    carrying out the contract or agreement.” Department of the Interior and Related Agencies
    Appropriation Act, 1991, Pub. L. No. 101-512, 104 Stat. 1915, 1960 (codified in 25
    U.S.C. § 5301 et seq.). Certain civil claims against law enforcement officers carrying out
    their duties under such contracts are thus “afforded the full protection and coverage of the
    [FTCA].”
    Id. The Department
    of Interior’s Bureau of Indian Affairs (“BIA”) funds the SUPD
    under a contract with the Southern Ute Tribe. Under the contract, SUPD officers are
    considered federal employees for the purposes of the FTCA. See Dist. Ct. Doc. 23 at 6
    (determining that the Officers “were acting within the scope of the [contract] and are
    deemed BIA employees entitled to the protection of the FTCA for those torts covered by
    the Act”); Dist. Ct. Doc. 13-4 (providing the relevant page of the contract).
    2
    We “have an independent obligation” to determine whether we have subject
    matter jurisdiction under the FTCA. Garling v. U.S. EPA, 
    849 F.3d 1289
    , 1293 (10th
    Cir. 2017) (citation omitted). “Consequently, even if the government failed properly to
    raise and preserve the discretionary function defense . . . we nonetheless are bound to
    consider it.” Irving v. United States, 
    162 F.3d 154
    , 160 (1st Cir. 1998).
    The United States asserts that we need not address subject matter jurisdiction
    under the FTCA because, in Cox v. United States, 
    881 F.2d 893
    , 894 n.1 (10th Cir. 1989),
    we declined to decide a discretionary function exception issue that was not raised on
    appeal. Aplee. Suppl. Br. at 2. But in Cox, we held that the district court lacked subject
    matter jurisdiction under 28 U.S.C. § 1346(b)(1), another provision of the 
    FTCA. 881 F.2d at 894-95
    . There was no reason to consider whether the discretionary function
    exception also deprived the court of jurisdiction.
    2
    After reviewing the supplemental briefs and the record, we conclude the
    discretionary function exception applies and the district court lacked subject matter
    jurisdiction over the negligence claim. We remand with instructions to dismiss the
    negligence claim.
    I. BACKGROUND
    In determining whether the United States retains sovereign immunity under the
    discretionary function exception, we “consider[] the allegations in the complaint as well
    as the evidence in the record.” Garcia v. U.S. Air Force, 
    533 F.3d 1170
    , 1175 (10th Cir.
    2008).
    A. Factual Background
    The Fight
    Mr. Martinez hosted a social gathering at his father’s house. Andrew Rossi and
    his girlfriend, Bridget Weaver, and Luana Price and her boyfriend, Fabian Pena, were
    guests.
    A fight began when Mr. Rossi hit Ms. Weaver and Mr. Pena intervened. Mr.
    Martinez forced Mr. Rossi and Mr. Pena outside, where the fight ended. Ms. Weaver,
    Mr. Pena, and Ms. Price left the gathering. Mr. Rossi remained.
    Around 1:00 a.m., Mr. Pena returned with Ms. Price and her two brothers. After
    they threatened Mr. Rossi, Mr. Martinez punched one of the Price brothers. A brawl
    ensued, and Mr. Martinez told Mr. Rossi they should “go get the bats.” App. at 105. The
    Price brothers, Mr. Pena, and Ms. Price left.
    3
    First Police Response
    One of the Price brothers called the police. Officer Herrera met them at an
    intersection near Mr. Martinez’s house. Officers Mitchell and Backer arrived as backup.
    Officer Mitchell and a fourth officer went to Mr. Martinez’s house to investigate
    what had happened. They parked in front, walked to the door, and announced themselves
    as police. Nobody answered. Officer Mitchell looked in a side window and saw Mr.
    Rossi in the house. He reported to Officers Backer and Herrera and then returned to
    regular duty.
    Second Police Response
    Officer Herrera met with a deputy from the county sheriff’s office and learned that
    Ms. Weaver might have returned to Mr. Martinez’s house after the fight.
    Id. at 990-92.
    In response, Officers Herrera and Backer returned to Mr. Martinez’s house around
    3:30 a.m. to look for Ms. Weaver and check on her welfare.
    Id. at 415,
    534, 993. As
    they neared the house, they “saw a vehicle that looked like [Ms.] Weaver’s car . . . in the
    driveway.”
    Id. at 993-94.
    Officer Herrera, who was in charge, decided to approach the house using a stealth
    tactic called a “blackout,” whereby police keep quiet, wear dark clothing, and park out of
    sight.
    Id. at 410,
    416-17, 994, 1050-51, 1059-61. The method is employed to protect
    officers from attack from inside the house. In domestic violence cases, it also is used to
    prevent perpetrators from injuring victims or attempting to silence them as police near.
    4
    Officer Mitchell arrived as backup. He drove past the house in his patrol car and
    saw two people in the yard look at him and go inside. He assumed they recognized him
    as a police officer, and he expected no response because Mr. Martinez had ignored the
    police earlier.
    Mr. Martinez thought the Officers’ car was the Price brothers’ SUV, which looked
    similar. Believing the brothers had returned to resume the fight, Mr. Martinez got a
    baseball bat from inside and hid behind a bush near where his driveway met the road.
    The Shooting
    The Officers walked quietly toward the house without using flashlights. Officers
    Herrera and Backer wore standard-issue black police jackets with the SUPD logo on the
    shoulders, but no police identification on the front.
    Id. at 308-09,
    1284-86. Officer
    Mitchell, wearing his standard gray police shirt and no jacket, walked behind Officers
    Herrera and Backer.
    The Officers heard the bush rustling and shined a flashlight. Mr. Martinez jumped
    out and ran toward them, raised the bat above his head, and shouted. The Officers drew
    their guns, and Officer Backer shot Mr. Martinez.
    B. Procedural Background
    The Complaint and Pretrial Rulings
    Mr. Martinez sued the Officers under Bivens v. Six Unknown Named Agents of
    Federal Bureau of Narcotics, 
    403 U.S. 388
    (1971), alleging excessive force and
    malicious prosecution. He sued the United States under the FTCA, alleging intentional
    5
    torts and negligence under Colorado law. The district court dismissed the intentional tort
    claims under 28 U.S.C. § 2680(h), which exempts certain torts from the FTCA’s waiver
    of sovereign immunity.
    The court later granted summary judgment to the Officers on the Bivens excessive
    force claim, holding they were entitled to qualified immunity. Although it found there
    was “conflicting evidence regarding the reasonableness of the officers’ conduct,” Dist.
    Ct. Doc. 87 at 5, the court concluded they did not violate clearly established law by
    shooting Mr. Martinez. The parties agreed to a dismissal of the Bivens malicious
    prosecution claim. Only the FTCA negligence claim against the United States remained
    for trial.
    Bench Trial
    After a six-day bench trial on the negligence claim, the district court ruled for the
    United States, finding that even if the Officers were negligent, they did not proximately
    cause Mr. Martinez’s injuries because Mr. Martinez’s ambush with the bat was a
    superseding cause. Alternatively, it found Mr. Martinez’s negligence accounted for more
    than 50 percent of the fault, barring recovery under Colorado’s comparative negligence
    statute. Mr. Martinez timely appealed, challenging only the district court’s disposition of
    the FTCA negligence claim.
    Supplemental Briefing on Jurisdiction
    At oral argument, we asked the parties whether the Officers’ decision to use the
    blackout approach was “a discretionary function” under 28 U.S.C. § 2680(a) and thus
    6
    exempt from the FTCA’s waiver of sovereign immunity. Because neither the district
    court nor the parties had raised the issue or prepared to discuss it at oral argument, we
    requested supplemental briefs addressing the discretionary function exception and its
    effect on subject matter jurisdiction. The parties submitted supplemental briefs
    simultaneously.
    II. DISCUSSION
    The district court lacked jurisdiction over Mr. Martinez’s negligence claim
    because the discretionary function exception to the FTCA’s waiver of sovereign
    immunity applies. First, the Officers exercised discretion in choosing how to approach
    Mr. Martinez’s house, and no statute, regulation, or policy prohibited their choice or
    required a different one. Nor has Mr. Martinez shown their actions violated the Fourth
    Amendment. Second, the decision to use the blackout approach was susceptible to public
    policy concerns regarding safety and effectiveness.
    A. Legal Background
    “The concept of sovereign immunity means that the United States cannot be sued
    without its consent.” Iowa Tribe of Kan. & Neb. v. Salazar, 
    607 F.3d 1225
    , 1232 (10th
    Cir. 2010) (quotations omitted). The FTCA provides “a limited waiver of [the United
    States’] sovereign immunity . . . for certain torts of federal employees acting within the
    scope of their employment.” United States v. Orleans, 
    425 U.S. 807
    , 813 (1976); see
    28 U.S.C. § 1346(b)(1). It includes exceptions to this limited waiver. See 28 U.S.C.
    7
    § 2680. “When an exception applies, sovereign immunity remains, and federal courts
    lack jurisdiction.” Garling v. U.S. EPA, 
    849 F.3d 1289
    , 1294 (10th Cir. 2017).
    Under the FTCA’s discretionary function exception, the United States does not
    waive its immunity for claims “based upon the exercise or performance or the failure to
    exercise or perform a discretionary function or duty on the part of a federal agency or an
    employee of the Government, whether or not the discretion involved be abused.”
    28 U.S.C. § 2680(a). “[T]he purpose of the exception is to prevent judicial second-
    guessing of legislative and administrative decisions grounded in social, economic, and
    political policy through the medium of an action in tort.” United States v. Gaubert, 
    499 U.S. 315
    , 323 (1991) (quotations omitted). When determining whether government
    conduct falls within the discretionary function exception, courts apply the two-part test
    set forth in Berkovitz v. United States, 
    486 U.S. 531
    , 536-37 (1988). See 
    Garling, 849 F.3d at 1295
    .
    First, courts determine whether the conduct was “discretionary”—that is, whether
    it was “a matter of choice for the acting employee.” 
    Berkovitz, 486 U.S. at 536
    . Conduct
    is not discretionary if it “violate[s] a federal statute, regulation, or policy that is both
    specific and mandatory.” Elder v. United States, 
    312 F.3d 1172
    , 1177 (10th Cir. 2002)
    (quotations omitted). Most circuits also have held conduct is not discretionary when it
    “exceeds constitutional bounds.” Loumiet v. United States, 
    828 F.3d 935
    , 944 (D.C. Cir.
    2016) (collecting cases); see, e.g., Medina v. United States, 
    259 F.3d 220
    , 225 (4th Cir.
    8
    2001) (explaining that “[f]ederal officials do not possess discretion to violate
    constitutional rights” (quotations omitted)).3
    Second, if the conduct was discretionary, courts determine whether it was “based
    on considerations of public policy.” 
    Berkovitz, 486 U.S. at 537
    . They “ask[]
    categorically (rather than case specifically) whether the kind of conduct at issue can be
    based on policy concerns.” Sydnes v. United States, 
    523 F.3d 1179
    , 1185 (10th Cir.
    2008). Courts “do not consider the employee’s ‘subjective intent in exercising the
    discretion . . . , but on[ly] the nature of the actions taken and . . . whether they are
    susceptible to policy analysis.’” 
    Garcia, 533 F.3d at 1176
    (quoting 
    Gaubert, 499 U.S. at 325
    ). “When established governmental policy, as expressed or implied by statute,
    regulation, or agency guidelines, allows a Government agent to exercise discretion, it
    must be presumed that the agent’s acts are grounded in policy when exercising that
    discretion.” 
    Gaubert, 499 U.S. at 324
    .
    If both parts of the Berkovitz test are met, the discretionary function exception
    applies, “the United States retains its sovereign immunity[,] and the district court lacks
    subject matter jurisdiction to hear the suit.” 
    Garcia, 533 F.3d at 1175-76
    . “Because the
    3
    See also Limone v. United States, 
    579 F.3d 79
    , 102 (1st Cir. 2009); Myers &
    Myers, Inc. v. U.S. Postal Serv., 
    527 F.2d 1252
    , 1261 (2d Cir. 1975); U.S. Fid. & Guar.
    Co. v. United States, 
    837 F.2d 116
    , 120 (3d Cir. 1988); Sutton v. United States, 
    819 F.2d 1289
    , 1293 (5th Cir. 1987); Raz v. United States, 
    343 F.3d 945
    , 948 (8th Cir. 2003);
    Nurse v. United States, 
    226 F.3d 996
    , 1002 (9th Cir. 2000). But see Kiiskila v. United
    States, 
    466 F.2d 626
    , 627-28 (7th Cir. 1972) (concluding the discretionary function
    exception applied to government conduct that was “constitutionally repugnant” and in
    violation of the First Amendment).
    9
    discretionary function exception is jurisdictional, the burden is on [the plaintiff] to prove
    that it does not apply.” Hardscrabble Ranch, L.L.C. v. United States, 
    840 F.3d 1216
    ,
    1220 (10th Cir. 2016); accord Aragon v. United States, 
    146 F.3d 819
    , 823 (10th Cir.
    1998) (“The discretionary function exception poses a jurisdictional prerequisite to suit,
    which the plaintiff must ultimately meet as part of his overall burden to establish subject
    matter jurisdiction.” (quotations omitted)). If the plaintiff fails to make the necessary
    showing under Berkovitz, “[t]he [discretionary function] exception applies even if the
    governmental employees were negligent.” 
    Aragon, 146 F.3d at 822
    .
    B. Analysis
    We first determine whether use of the blackout approach was within the Officers’
    discretion. Finding that it was, we then assess whether their conduct was based on public
    policy concerns.
    Discretion
    Mr. Martinez argues the Officers lacked discretion to use the blackout approach
    because it violated (1) the BIA Office of Justice Services Law Enforcement Handbook
    (“BIA Handbook”),4 and (2) the Fourth Amendment. But he has not shown that the
    Officers “violated a federal statute, regulation, or policy” by using the blackout approach,
    4
    The BIA Handbook contains a set of policies that federally recognized tribes
    may adopt. The SUPD has adopted the Handbook.
    10
    
    Elder, 312 F.3d at 1177
    , or that the approach “exceed[ed] constitutional bounds,”
    
    Loumiet, 828 F.3d at 944
    . Their conduct was therefore discretionary.
    a. BIA Handbook
    The BIA Handbook does not address the blackout approach. Mr. Martinez
    acknowledges that “[t]here are no official BIA or SUPD policies, procedures, or other
    guidelines regarding the blackout approach. Use of the blackout approach is left to
    officer discretion . . . .” Aplt. Br. at 5 (citing App. at 163-64).
    Even so, Mr. Martinez argues the Officers violated the following provisions of the
    BIA Handbook when they used the blackout approach:
    (1) “All commissioned police officers will wear the approved and
    issued police uniform when on duty,” App. at 1305;
    (2) “Officers not in uniform will fully identify themselves as
    officers and exhibit their badges or credentials prior to
    initiating any field interview,”
    id. at 1307;
    and
    (3) When “initiat[ing] a contact” with the public, officers must
    “identify themselves as law enforcement officers as soon as
    possible if it is not evident,” and must avoid “force or
    coercion,”
    id. at 1306.
    Mr. Martinez argues that these policies prohibited the Officers from using the blackout
    approach. We disagree because the Officers did not violate these provisions.
    First, Officers Herrera and Backer wore standard-issue police jackets that were
    part of their uniforms. App. at 305-06, 382, 510, 1093. Officer Mitchell wore his
    standard gray police uniform without a jacket.
    Id. at 219.
    They did not, therefore, violate
    the BIA requirement that “police officers will wear the approved and issued police
    11
    uniform,” App. at 1305, nor the provision pertaining to “[o]fficers not in uniform,”
    id. at 1307.
    Second, although the Officers did not identify themselves as police as they
    approached the property, they did not “initiate a contact” with Mr. Martinez.
    Id. at 1306.
    He did when he ran out from behind a bush waving a bat and yelling. Officer Herrera
    testified that, had she been able to initiate contact with Mr. Martinez, she had “[no]
    intention of concealing [her] identity as a police officer.”
    Id. at 995.
    Officers Mitchell
    and Backer gave similar testimony. See
    id. at 323-24,
    415-16. The Officers did not,
    therefore, violate the provision that they identify themselves as police and avoid force or
    coercion when “initiat[ing] a contact” with the public.
    Id. at 1306.
    Third, the trial testimony supports that the BIA Handbook allowed the blackout
    approach. BIA Chief of Police, John Roberts Burge, testified that the Officers’ approach
    was consistent with the Handbook.
    Id. at 1116-18.
    Officer Mitchell also noted that
    police field training teaches the blackout approach and instructs officers to use the
    approach “depend[ing] on the nature of the contact and prior history with the residence
    itself and also the people that [the officers are] attempting to contact.”
    Id. at 281.
    The
    SUPD teaches officers that use of the approach is “situationally dependent.”
    Id. at 785.5
    5
    Although Officer Mitchell said during cross examination at trial that some of the
    BIA Handbook’s provisions seem inconsistent with the blackout approach, App. at
    381-84, our analysis above shows those sections do not prohibit the blackout approach.
    12
    In short, Mr. Martinez has not shown that the Officers’ use of the blackout
    approach violated a “specifically prescribe[d] . . . course of action” in the BIA Handbook.
    
    Garling, 849 F.3d at 1295
    (quotations omitted).
    b. Fourth Amendment
    Mr. Martinez argues the blackout approach violated his Fourth Amendment rights
    and therefore was not discretionary. He relies on Florida v. Jardines, 
    569 U.S. 1
    , 6
    (2013), Kentucky v. King, 
    563 U.S. 452
    , 469-470 (2011), and Manzanares v. Higdon, 
    575 F.3d 1135
    , 1146 (10th Cir. 2009), to argue that “[a] homeowner has a clear Fourth
    Amendment right to choose not to speak with officers who may appear at his home
    without a warrant.” Aplt. Suppl. Br. at 5-6.6 He contends the Officers violated that right
    by approaching the house in a clandestine manner despite his failure to answer the door
    for Officer Mitchell earlier that night. Although, as noted above, most circuits have held
    that conduct is not discretionary under the FTCA when it violates the Constitution, this
    circuit has not addressed this issue. We need not do so here because, as explained below,
    Mr. Martinez’s arguments for a Fourth Amendment violation are not persuasive.
    6
    In Jardines, the Supreme Court said that police officers may knock on a front
    door, but that using a drug-sniffing dog on a home’s curtilage is a search under the Fourth
    
    Amendment. 569 U.S. at 11-12
    . In King, the Court stated that when police knock on a
    door, “the occupant has no obligation to open the door or to 
    speak.” 563 U.S. at 469-70
    .
    In Manzanares, we held that an officer violated a homeowner’s Fourth Amendment
    rights because he “remained in [the] home without a warrant or valid exception to the
    warrant requirement” after the homeowner “unequivocally asked [him] to 
    leave.” 575 F.3d at 1143
    , 1146.
    13
    i. Additional legal background
    The Fourth Amendment provides that “[t]he right of the people to be secure in
    their persons, houses, papers, and effects, against unreasonable searches and seizures,
    shall not be violated.” U.S. Const. amend. IV. “Houses, for Fourth Amendment
    purposes, include a home’s curtilage . . . .” United States v. Carloss, 
    818 F.3d 988
    , 992
    (10th Cir. 2016) (quotations omitted).
    Even without a warrant or reasonable suspicion, “a police officer, like any member
    of the public, has an implied license to enter a home’s curtilage to knock on the front
    door, seeking to speak with the home’s occupants.” Id.; accord United States v. Shuck,
    
    713 F.3d 563
    , 567 (10th Cir. 2013) (“[A] ‘knock and talk’ is a consensual encounter and
    therefore does not contravene the Fourth Amendment, even absent reasonable suspicion.”
    (quotations omitted)).
    A knock and talk becomes a nonconsensual seizure when occupants reasonably
    believe they cannot refuse to speak with the police—that is, when the encounter becomes
    “coercive.” United States v. Reeves, 
    524 F.3d 1161
    , 1167 (10th Cir. 2008); compare
    id. at 1168-69
    (holding that officers seized a homeowner when they pounded on his door and
    windows and yelled for 20 minutes between 2:30 a.m. and 3:00 a.m.) with United States
    v. Hernandez-Chaparro, 357 F. App’x 165, 167 (10th Cir. 2009) (unpublished) (holding
    that an officer did not violate the Fourth Amendment when he knocked on a
    homeowner’s door before 6:00 a.m. and asked to check on the welfare of children in the
    14
    house).7 We have held that an early-morning knock and talk by multiple officers is not
    “inherently coercive.” United States v. Abdenbi, 
    361 F.3d 1282
    , 1288 (10th Cir. 2004).
    When a homeowner preempts a knock and talk by attacking the approaching
    officers, the officers’ approach “do[es] not implicate the Fourth Amendment.” United
    States v. Carter, 
    360 F.3d 1235
    , 1239 (10th Cir. 2004). At that point, the officers have
    neither “seized anything or anyone,” nor “conducted a search.”
    Id. ii. Analysis
    The Officers planned to knock on Mr. Martinez’s front door when they
    approached his house. App. at 995. Mr. Martinez prevented them from reaching the
    door by charging at them with a bat. The Officers neither seized him, searched his
    property, nor even initiated contact. See 
    Carter, 360 F.3d at 1238-40
    (holding that no
    search or seizure occurred when officers walked up a driveway at midnight to conduct a
    knock and talk, but the homeowner ran out of the garage “in a combative manner” before
    they reached the door).8
    7
    Although not precedential, we find the reasoning of this unpublished decision
    instructive. See 10th Cir. R. 32.1 (“Unpublished decisions are not precedential, but may
    be cited for their persuasive value.”); see also Fed. R. App. P. 32.1.
    8
    We thus do not address whether the Fourth Amendment would have allowed the
    Officers to enter the house to check on Ms. Weaver even if Mr. Martinez had refused.
    See, e.g., United States v. Sanders, 
    956 F.3d 534
    , 539-40 (8th Cir. 2020) (holding that
    police officers’ warrantless entry into a house to check on a potential victim of domestic
    violence did not violate the Fourth Amendment under the community caretaking
    exception).
    15
    And even if the Officers had been able to carry out their plan, their approach at
    3:30 a.m. to check on Ms. Weaver was reasonable despite Mr. Martinez’s failure to
    answer the door for Officer Mitchell at 1:30 a.m. See Brigham City, Utah v. Stuart, 
    547 U.S. 398
    , 403 (2006) (“[T]he ultimate touchstone of the Fourth Amendment is
    ‘reasonableness.’”). Officer Mitchell testified that he did not know about a domestic
    violence incident when he approached the house at 1:30 a.m. App. at 301. Officer
    Herrera ordered the second visit only after confirming with corroborating witnesses that
    Mr. Rossi had attacked Ms. Weaver and that she might be at the house.
    Id. at 990-92.
    The Officers stopped at the property and approached the house only after seeing her car
    in the driveway, where it had not been when Officer Mitchell knocked earlier. See App.
    at 104, 535, 993-94. They approached with the intent of “knock[ing] and ask[ing] to
    speak with [Ms.] Weaver.”
    Id. at 995;
    see also 
    Carloss, 818 F.3d at 992
    (“[A] police
    officer, like any member of the public, has an implied license to enter a home’s curtilage
    to knock on the front door, seeking to speak with the home’s occupants.”). Mr. Martinez
    identifies no case holding that a welfare check on a victim of domestic violence is
    coercive simply because the police received no response when they approached the house
    hours earlier.
    Finally, Jardines, King, and Manzanares do not apply here. The Officers did not
    search Mr. Martinez’s property, see 
    Jardines, 569 U.S. at 11-12
    , nor compel him to
    answer questions, see 
    King, 563 U.S. at 469-70
    . Nor did they “remain[] in his home
    16
    without a warrant or valid exception to the warrant requirement” after he “unequivocally
    asked [them] to leave.” 
    Manzanares, 575 F.3d at 1143
    , 1146.
    Based on the foregoing, Mr. Martinez cannot establish that the Officers violated
    his Fourth Amendment rights.
    * * * *
    Because Mr. Martinez has not shown the Officers’ use of the blackout approach
    violated the BIA Handbook or the Constitution, and because the evidence showed they
    chose the blackout approach rather than other options, the Officers’ decision was
    discretionary. See 
    Berkovitz, 486 U.S. at 536
    ; see also Hardscrabble 
    Ranch, 840 F.3d at 1220
    (“[T]he burden is on [the plaintiff] to prove that [the discretionary function
    exception] does not apply.”).
    Public Policy
    Mr. Martinez fails to overcome the “presum[ption] that the [Officers’] acts [were]
    grounded in policy.” 
    Gaubert, 499 U.S. at 324
    ; see also 
    Berkovitz, 486 U.S. at 537
    . A
    police department’s decision to teach the approach and an officer’s decision to use it
    implicate policy concerns about safety and effectiveness. The trial evidence showed that
    the method (1) protects officers from potential attack when they approach homes, App. at
    405, 533, 886, 1117-19, 1325, (2) prevents perpetrators of domestic violence from
    silencing victims as police near,
    id. at 1120,
    and (3) avoids causing a public disruption
    late at night,
    id. at 292.
    17
    On the other hand, the method risks that officers will be misperceived as
    trespassers,
    id. at 157,
    167-68, 1328, jeopardizing officer and homeowner safety. The
    SUPD cautions trainees about this danger.
    Id. at 157.
    The blackout approach thus
    requires departments and officers to weigh safety and effectiveness considerations. See
    Johnson v. U.S., Dep’t of Interior, 
    949 F.2d 332
    , 339 (10th Cir. 1991) (explaining that
    “the balancing of safety objectives against . . . practical considerations” sufficiently
    implicated public policy (footnote omitted)).
    Mr. Martinez argues that the Officers’ use of the blackout approach did not
    involve public policy because it was “chosen for the purpose of forcing persons to make
    contact with officers.” Aplt. Suppl. Br. at 9. That is, the Officers sought merely to
    prevent Mr. Martinez from refusing to speak to them. But in assessing the public policy
    step of the Berkovitz analysis, “we do not consider the employee’s ‘subjective intent in
    exercising the discretion.’” 
    Garcia, 533 F.3d at 1176
    (quoting 
    Gaubert, 499 U.S. at 325
    ).
    We consider only “the nature of the actions taken and . . . whether they are susceptible to
    policy analysis.”
    Id. (quotations omitted).
    As discussed, the blackout approach is
    susceptible to a public policy analysis. It does not matter whether the Officers in this
    particular case subjectively considered policy issues, though the evidence showed they
    weighed such concerns. See App. at 417, 526.
    Mr. Martinez also relies on 
    Gaubert, 499 U.S. at 325
    n.7, and Daigle v. Shell Oil
    Co., 
    972 F.2d 1527
    , 1538 (10th Cir. 1992), to argue the Officers’ conduct was merely
    “ordinary discretion” not grounded in policy, and therefore does not meet the second step
    18
    of Berkovitz. Aplt. Suppl. Br. at 8. But in those cases, we explained that “ordinary
    discretion” encompasses acts such as driving a car in the course of official duties. See
    
    Gaubert, 499 U.S. at 325
    n.7; 
    Daigle, 972 F.2d at 1538
    . The discretion to use the
    blackout approach, by contrast, involves safety and effectiveness concerns crucial to
    police investigations.9
    Finally, Mr. Martinez asserts that the blackout approach’s “risk to both officer and
    civilian safety makes it difficult, if not impossible, to argue that [the Officers’] decisions
    were based on considerations of public policy.” Aplt. Suppl. Br. at 10. But, as discussed,
    the blackout approach requires officers and police departments to balance competing
    9
    See, e.g., Suter v. United States, 
    441 F.3d 306
    , 311-12 (4th Cir. 2006) (holding
    that an undercover FBI agent’s discretionary participation in the crimes the FBI was
    investigating was susceptible to a policy analysis); Deuser v. Vecera, 
    139 F.3d 1190
    ,
    1195-96 (8th Cir. 1998) (holding that National Park Service rangers’ discretionary
    decisions about arresting and releasing the plaintiff were rooted in policy concerns about
    the safety of other parkgoers); Mesa v. United States, 
    123 F.3d 1435
    , 1438 (11th Cir.
    1997) (holding that “[t]he decision as to how to locate and identify the subject of an arrest
    warrant prior to service of the warrant is susceptible to policy analysis” involving “such
    factors as the potential threat the subject poses to public safety and the likelihood that the
    subject may destroy evidence”); Hart v. United States, 
    630 F.3d 1085
    , 1090 (8th Cir.
    2011) (“We readily conclude a federal law enforcement officer’s on-the-spot decisions
    concerning how to effectuate an arrest—including how best to restrain, supervise, control
    or trust an arrestee—fall within the discretionary function exception to the FTCA absent
    a specific mandatory directive to the contrary.”).
    19
    safety concerns. And Mr. Martinez does not explain why such risks would preclude
    consideration of policy concerns.10
    * * * *
    Policy concerns inform the blackout approach. Mr. Martinez has not shown
    otherwise. The Officers’ conduct thus satisfied the second step of Berkovitz. The
    discretionary function exception applies, and the United States retains sovereign
    immunity.
    III. CONCLUSION
    The district court lacked subject matter jurisdiction over Mr. Martinez’s
    negligence claim. We therefore remand with instructions to dismiss the negligence
    claim.

    To the extent Mr. Martinez argues the discretionary function exception does not
    apply because the Officers “ignore[d] duties under tort law,” Aplt. Suppl. Br. at 9, we
    note that “[t]he [discretionary function] exception applies even if the governmental
    employees were negligent,”
