Opinion for the Court filed by Circuit Judge SENTELLE.
Dissenting opinion filed by Chief Judge MIKVA.
SENTELLE, Circuit Judge:Appellants Doris and Otis Andrews brought this action against officials and representatives of the United States Park Police, United States Department of the Interior, and the United States, for the wrongful death of the Andrewses’ son, Gino Andrews (“Andrews”). The district court granted summary judgment against appellants on their claims of both constitutional and common law torts against appel-lees. After reviewing appellants’ allegations of error, we affirm the decision of the district court.
I. Factual Background
This case arises from a bizarre series of events that began when Andrews urinated against the exterior wall of a public restroom facility at Hains Point in East Potomac Park. United States Park Police Officer Thomas Wilkins approached Andrews and advised him that he was being charged with urinating in public, and that Andrews would have to accompany Wilkins to the Park Police station to post collateral. When Wilkins moved toward Andrews with handcuffs, Andrews fled, running around *1267the restrooms, across the East Potomac Golf Course, and finally reaching the Washington Channel. With Wilkins in pursuit, Andrews climbed down into the Channel and began swimming toward Fort McNair on the opposite bank.
Wilkins pursued Andrews, first on foot, and then on his police scooter. Wilkins continuously notified the Park Police dispatcher of Andrews’s actions and, when Andrews entered the Channel, directed the dispatcher to contact the Metropolitan Police Department Harbor Patrol. The dispatcher also sent additional Park Police patrol vehicles and a Park Police helicopter to the scene of Andrews’s entry into the Channel.
Andrews swam approximately thirty to forty feet across the Channel, then turned back toward the Hains Point shore. At this point, it appeared that he began to tire and was in danger of drowning. After some hesitation and at the urging of a bystander, Wilkins went to one of the patrol cars, removed a life ring attached to fifty feet of rope, and threw it toward Andrews. The ring did not reach Andrews, and the rope tangled. One of Wilkins’s fellow officers radioed the dispatcher to send another patrol car with a life ring, while Wilkins, without apparent urgency, retrieved the life ring, untangled the rope, walked closer to the Channel’s edge, and threw the ring within approximately two feet of Andrews. Andrews was by this time apparently unconscious and unable to reach for the life ring.
Wilkins. then removed his gun belt in preparation for a swimming rescue, but was dissuaded by fellow officers, who pointed out a District of Columbia Fire Boat and a private motor boat approaching Andrews. The officers hailed the private boat, piloted by George and Jennifer Sozio, who guided it alongside Andrews. Ms. So-zio extended her leg into the water for Andrews to grab onto, then, seeing that Andrews was unconscious and face-down in the water, reached toward Andrews with her arm. At the direction of the police, she also threw a life jacket toward Andrews. Ms. Sozio yelled to the police that Andrews had gone underwater, stating, “I need to go in, I’ve been trained.” They directed her not to go in the water, stating that “[h]e’s an escaped prisoner, and could be dangerous.”
Instead, the police signalled the Sozios to bring their boat to the Channel’s edge, where a police officer boarded and directed them to return to Andrews. Although the Sozios returned their boat to where the life jacket was floating, Andrews’s body had dropped out of sight. The officer told Ms. Sozio that Andrews “was an escape [sic] prisoner and was running from us. He jumped into the water himself, and I was afraid he was dangerous and would commandeer the boat, and force you to take him some where [sic], or take you as a hostage.”
Approximately one-half hour later, the Harbor Patrol recovered Andrews’s body from the Washington Channel. The Police immediately transported Andrews to the George Washington Hospital Emergency Room, where he was pronounced dead. The autopsy revealed the presence of PCP, marijuana residues, and alcohol in Andrews’s bloodstream at the time of his death.
II. Discussion
A. Appellants’ Constitutional Tort Claims
Appellants claim that police actions toward Andrews — failing to rescue him and interfering with the Sozios’ private efforts to rescue him — deprived Andrews of his Fifth Amendment right to life, liberty, and property without due process of law, thereby making out a constitutional tort if the police were acting under federal law, or a violation of 42 U.S.C. § 1983 if the police were acting under District of Columbia law. As the district court properly noted below, a constitutional tort claim against the government is subject to a heightened pleading standard. Smith v. Nixon, 807 F.2d 197, 200 (D.C.Cir.1986). To meet this standard, a claimant must make “nonconclusory allegations” that are “sufficiently precise to put defendants on notice of the nature of the claim and enable them to *1268prepare a response and, where appropriate, a summary judgment motion on qualified immunity grounds.” Hobson v. Wilson, 737 F.2d 1, 29 (D.C.Cir.1984).
Qualified immunity is available to federal and state officials charged with constitutional torts so long as “their conduct does not violate clearly established statutory or constitutional rights of which a reasonable person would have known.” Harlow v. Fitzgerald, 457 U.S. 800, 818, 102 S.Ct. 2727, 2738, 73 L.Ed.2d 396 (1982) (citations and footnote omitted). See also Harris v. District of Columbia, 932 F.2d 10, 13 (D.C.Cir.1991) (“Officials are liable for committing constitutional torts, ... only if they knew, or were unreasonable in not knowing, that the behavior violated the Constitution.”). Applying this standard, we must agree with the district court that appellants “have failed to show that defendants violated , a ‘clearly established’ right, such that a reasonable officer could or should have known that he was violating the Constitution.” Memorandum Opinion, No. 88-1326, slip op. at 9, 1990 WL 102777 (D.D.C. July 11, 1990).
First, the police, as state officers, had no constitutional duty to rescue Andrews. See Bradberry v. Pinellas County, 789 F.2d 1513 (11th Cir.1986) (county had no constitutional duty to provide protective services to its citizens, and thus was not liable when its lifeguards failed to save decedent); cf. also DeShaney v. Winnebago County Dept. of Soc. Servs., 489 U.S. 189, 197, 109 S.Ct. 998, 1004, 103 L.Ed.2d 249 (1989) (“a State’s failure to protect an individual against private violence simply does not constitute a violation of the Due Process Clause”); Archie v. City of Racine, 826 F.2d 480 (7th Cir.1987) (emergency dispatcher’s negligent failure to send an ambulance did not unconstitutionally deprive decedent of life without due process); accord, Jackson v. Byrne, 738 F.2d 1443 (7th Cir.1984). Thus, the police officers’ failure to rescue Andrews is not a constitutional tort.
Nor is it a constitutional violation for a state officer to attempt an ineffectual rescue. See Jackson v. City of Joliet, 715 F.2d 1200 (7th Cir.1983) (police action directing traffic away from accident scene, thus barring potential private rescue attempts, does not constitute deprivation of life without due process). Indeed, since “the federal Constitution does not require states to expend their resources to guard against such accidents, ... it would be anomalous to hold them liable when they attempt to do so and fail in their effort.” Bradberry, 789 F.2d at 1517 (citation omitted). Thus, appellants’ allegations that the police were negligent in their rescue attempts is not a constitutional tort.
On the other hand, at least one circuit has held that police action deliberately or recklessly interfering with ongoing private rescue efforts may establish a constitutional tort. In Ross v. United States, 910 F.2d 1422 (7th Cir.1990), the Seventh Circuit held that an Assistant Deputy Sheriff committed a constitutional tort by interfering with private rescue efforts to save a twelve-year old child who drowned in Lake Michigan. Although two lifeguards, two fire fighters, one police officer, and two civilian scuba-divers arrived at the scene almost immediately, the local Deputy Sheriff barred all rescue attempts, asserting that it was county policy to allow only “authorized” fire department divers to engage in rescues. Potential rescuers were thus forced to stand idle until the “authorized” fire department divers arrived at the scene thirty minutes after the child had entered the water.
The Seventh Circuit found that the Deputy was aware of “a known and significant risk of death,” but “consciously chose a course of action that ignored the risk.” Ross, 910 F.2d at 1433 (citation omitted). The court therefore concluded that “a reasonable police officer in Deputy Johnson’s position should have known that he could not use [his] authority to prevent private rescue efforts.” Id. Accordingly, the claimants made out a valid claim for a constitutional tort, against which the Deputy lacked qualified immunity.
Here, appellants claim that the police interfered with the Sozios’ private res*1269cue efforts, thus making out a constitutional tort against Andrews. However, several factors distinguish Ross from the case at hand. First, in Ross, well-equipped, would-be rescuers had already arrived at the scene and were preparing to begin rescue efforts when the Deputy Sheriff arrived and ordered them to desist. The Deputy Sheriff in Ross directly and physically prevented these rescue efforts, ordering all persons on the scene to cease such efforts, threatening to arrest scuba divers who said they would attempt the rescue at their own risk, and positioning his boat so that scuba divers were unable to enter the water. Ross, 910 F.2d at 1424. Thus, the Deputy used his authority as a state actor to intrude into a purely private rescue effort.
In the present case, the police enlisted the Sozios’ assistance, waving them to the site and requesting that they throw a life jacket to Andrews. Thus, rather than using their authority to interfere in a private rescue, the police officers used their authority to involve the Sozios in the police rescue efforts. Given that they were responsible for Ms. Sozio’s involvement, the police were entitled, if not obliged, to prevent Ms. Sozio from endangering her life in the course of a police rescue effort. Based on the decedent’s drastic behavior in the face of a misdemeanor charge, the police could and did conjecture that Andrews was wanted for other charges — perhaps involving a violent crime — or that he was acting under the influence of drugs. (Andrews was in fact also subject to warrant for his arrest at the time on felony charges of possession of cocaine with intent to distribute.) Thus, the facts of this case are much less troubling than those in Ross, given the fact that the police solicited Ms. Sozio’s aid as part of an ongoing police rescue effort, that the police could not have known Ms. Sozio’s level of safety training or skills, and that they were concerned with Andrews’s bizarre behavior.
Even if such action could be construed by this Court as recklessly interfering with a private rescue effort, such a conclusion could not have been clear to the police at the time of the rescue. A federal or state officer is protected by qualified immunity unless the officer reasonably could have known that his or her action would violate an individual’s constitutional rights. This judgment turns on “the ‘objective legal reasonableness’ of the action, assessed in light of the legal rules that were ‘clearly established’ at the time it was taken.” Anderson v. Creighton, 483 U.S. 635, 639, 107 S.Ct. 3034, 3038, 97 L.Ed.2d 523 (1987) (citations omitted). As this Court has emphasized, “ ‘the right the official is alleged to have violated must have been “clearly established” in a ... particularized ... sense: The contours of the right must be sufficiently clear that a reasonable official would understand that what [that official] is doing violates that right.’ ” Brogsdale v. Barry, 926 F.2d 1184, 1191 (D.C.Cir.1991) (quoting Anderson, 483 U.S. at 639, 107 S.Ct. at 3039). While it should have been clear to the police that they could not “arbitrarily assert [their] power so as to cut short a person’s life,” Ross, 910 F.2d at 1433, it certainly could not have been clear to them that they were required to refrain from taking any action when a private citizen, drawn into a police rescue operation, was about to expose herself to substantial danger, of which she was not completely aware. Whatever constitutional right to unhindered private rescue efforts Andrews may have had, it was by no means clearly established that such a right precluded police efforts directed at the safety of the potential private rescuer. Thus, appellants do not state a cognizable constitutional tort claim in this case.
Therefore, neither a Bivens theory constitutional tort claim nor a section 1983 claim will lie, so we need not determine whether the police were acting under federal or District of Columbia authority in order to determine which action would be appropriate. Rather, we need only affirm the district court’s decision granting summary judgment for appellees, as appellants’ failure to make out a claim for a constitutional tort vitiates both causes of action.
B. Appellants’ Common Law Tort Claims
The district court also granted summary judgment against appellants for their com*1270mon law claims against the United States, including 1) negligence, in the form of the police officers’ individual negligence during rescue efforts, and the United States’ negligence in ineffectively supervising and training its police officers; 2) liability under the “last clear chance” doctrine; and 3) willful and wanton negligence. As a matter of law, the district court found that appellants’ claims under negligence were barred by the decedent's contributory negligence, and that no evidence supported a cause of action for “last clear chance” or willful and wanton negligence.
In the District of Columbia, contributory negligence is a complete bar to recovery. Wingfield v. Peoples Drug Store, 379 A.2d 685, 687 (D.C.1977). It is true that contributory negligence is virtually always a question of fact for the jury. Jeffries v. Potomac Dev. Corp., 822 F.2d 87, 91 (D.C.Cir.1987). However, this case presents just such an “unusual” and “extraordinary” case as to justify the district court in removing the question of contributory negligence from the jury. See id. As the district court found, three uncontroverted facts make out a clear case for contributory negligence: Andrews was fleeing law enforcement officers in an effort to evade arrest; Andrews swam in a Channel in violation of federal regulations, 36 C.F.R. § 7.96(e); and Andrews was under the influence of PCP, marijuana, and alcohol. Given these uncontroverted facts, we find no error in the district court's conclusion that no reasonable jury could find an absence of contributory negligence. Andrews’s contributory negligence thus bars appellants’ negligence claims against the United States.
So, too, fails appellants’ claim that the United States could have avoided Andrews’s death under the “last clear chance” doctrine. Under District of Columbia law, a plaintiff may make out a claim for negligence under the “last clear chance” doctrine by alleging
(1) that plaintiff was in a position of danger caused by negligence of both plaintiff and defendant; (2) that the plaintiff was oblivious of the danger or unable to extricate himself from the position of danger; (3) that defendant was aware, or by the exercise of reasonable care should have been aware of the plaintiff’s danger and obliviousness or inability to extricate himself from the danger; and (4) the defendant with means available to him was by the exercise of reasonable care able to avoid [harming] plaintiff after he became aware of the latter’s danger and inability to extricate himself from danger, and failed to do so.
Queen v. Washington Metropolitan Area Transit Authority, 842 F.2d 476, 481 (D.C.Cir.1988), quoting Washington Metro. Area Transit Auth. v. Jones, 443 A.2d 45, 51 (D.C.1982). Here, appellants’ claim fails on the first prong of the test, as decedent was in a position of danger by virtue only of his own actions. Cf., e.g., Cameron v. City of Pontiac, 813 F.2d 782 (6th Cir.1987) (police action not proximate cause of death where decedent ran onto highway and was killed while fleeing arrest).
Finally, we find no error in the judge’s conclusion that there was no willful or wanton negligence on the part of the police. To constitute willful or wanton negligence, the police actions must involve “such reckless disregard of security and right as to imply bad faith.” 3 S. Speiser, C. Krause, A. Gans, The American Law of Torts § 10.1, at 354 (1986) (footnote omitted). Here, even in the worst possible light, the evidence shows only that the police were less than enthusiastic in the performance of their jobs and placed a higher value on the safety of Ms. Sozio than they did upon the possibility that she could save Andrews. This is insufficient to establish bad faith. Instead, the uncontroverted facts indicate that the police provided basic rescue services: throwing a life ring to Andrews, contacting the police helicopter and Harbor Patrol, and utilizing the assistance of the Sozios’ private boat-actions that are hardly unresponsive to Andrews’s danger. Accordingly, the district court did not err in granting summary judgment on appellant’s claims that the police engaged in willful and wanton negligence.
*1271We find our colleague’s dissent on this point mystifying. The dissent admits that “the Park Police ... owed the Sozios a countervailing duty not to endanger their lives as a part of the rescue operation” (dissent at 3), but then asserts that carrying out that duty should subject them to liability. Justifying this conclusion, our colleague asserts that “the stated reason given by the Park Police as to why Ms. Sozio should not proceed further was not true_” Id. Though our colleague promises to discuss that point more fully below, the further discussion is not enlightening. As the entire dissent hinges upon this supposed untruth, it would seem incumbent upon our colleague to move beyond the simple assertion that the statement by the police was “false” and “patently untrue.” Dissent at 1274 and 1276.
In introducing his accusation of untruth, our colleague asserts that the Park Police warning to Ms. Sozio not to get in the water with Andrews “because Andrews was an escaped prisoner and could be dangerous ... was false: Andrews was not an escaped prisoner_” Dissent at 1274. Our colleague does admit that “one could call him a fleeing misdemeanant,” id., but he never explains why a misdemeanant does not become an escaped prisoner when he is arrested and then flees.1 If there is a distinction, our colleague explains neither its origin nor its significance. He certainly never explains why officers in the course of emergency duty should be held accountable for whatever technical difference in terminology there might be when shouting a warning to citizens whom he concedes they have a duty to protect.
Our colleague also takes exception to the police assertion to the Sozios that Andrews “could be dangerous.” From the point of view of the police officers not blessed with our hind-sight vantage, this statement was entirely accurate. Our colleague writes that Andrews “was already unconscious at the time Ms. Sozio attempted her rescue, and therefore posed no conceivable threat to her or anyone else.” Dissent at 1274. What he neglects to mention is that the Park Police had no way of knowing this at the time, and we know this only as a result of Ms. Sozio’s subsequent witness statement. In fact, Ms. Sozio also recounts that “someone in the policeman’s direction yell[ed] ‘throw the life preserver,’ ” which would seem to confirm that those on shore were not aware that Andrews was unconscious.
While we take no delight in writing ill of the dead, the evidence is uncontested that Gino Andrews, at the time of death, had a blood ethanol level of .03 percent, a blood phencyclidine level of 0.012 mg percent and a lung phencyclidine level of 0.029 mg percent, as well as a positive response for blood cannabinoids. The record further discloses that a phencyclidine “user readily loses his orientation while swimming or immersed and frequently drowns, sometimes in very small amounts of water.” Nothing in this evidence is inconsistent with the apparent proposition that these officers had no reason to believe that the appellant would become unconscious or drown faster than anyone else, except the same evidence that they had that he was dangerous; that is, that he acted in a dangerous and bizarre fashion. To assert that “the warnings to Ms. Sozio that Gino Andrews was an ‘escaped prisoner [who] could be dangerous’ were patently untrue,” is simply subjecting the officers’ conduct to our hind-sight. See dissent at 1276. So, too, is our colleague’s assertion that “what is truly bizarre is the behavior of the United States Park Police.” Dissent at 1274. Granted, his statement that “urinating in public ... and fleeing arrest do not transform a 21 year old into a hardened criminal who poses a threat to private rescuers,” is literally a true one. See dissent at 1274. It is, however, also true that fleeing from police and leaping into the Washington Channel after a misdemeanor arrest is not the act of an ordinary misdemeanant, but rather the behavior of a desperate fugitive or one on drugs. That the record discloses *1272Andrews to be at least somewhat deserving of both these labels should come as no surprise.
III. CONCLUSION
For the foregoing reasons, the judgment of the district court is
Affirmed.
. Though the dissent questions the word "arrested," we accept as true the allegations of the complaint not contested by pleading or affidavit. “This is an action arising from the arrest and drowning of Gino Marquette Andrews.” Complaint at ¶ 1 (emphasis supplied).
