OPINION

WILKINSON, Circuit Judge:

We granted en banc review in this case to define the contours of qualified immunity under 42 U.S.C. § 1983 when a plaintiff alleges an affirmative duty on the part of a police officer to protect citizens from the actions of a third party. The plaintiff in this action, Carol Pinder, seeks to impose civil liability against Officer Donald Johnson of the Cambridge, Maryland, Police Department for his failure to safeguard her children from the criminal depredations of plaintiff's ex-boyfriend. Pinder alleges that defendant's express promises to her created a "special relationship," which in turn gave rise to an affirmative duty to protect her under the Due Process Clause of the Fourteenth Amendment. We hold that no such due process right to protection was clearly established, DeShaney v. Winnebago County Dep't of Social Servs., 489 U.S. 189, 109 S.Ct. 998, 103 L.Ed.2d 249 (1989), and that Officer Johnson is thus entitled to qualified immunity.

I.

The facts of this case are genuinely tragic. On the evening of March 10, 1989, Officer Johnson responded to a call reporting a domestic disturbance at the home of Carol Pinder. When he arrived at the scene, Johnson discovered that Pinder's former boyfriend, Don Pittman, had broken into her home. Pinder told Officer Johnson that when Pittman broke in, he was abusive and violent. He pushed her, punched her, and threw various objects at her. Pittman was also screaming and threatening both Pinder and her children, saying he would murder them all. A neighbor, Darnell Taylor, managed to subdue Pittman and restrain him until the police arrived.

Officer Johnson questioned Pittman, who was hostile and unresponsive. Johnson then placed Pittman under arrest. After confining Pittman in the squad car, Johnson returned to the house to speak with Pinder again. Pinder explained to Officer Johnson that Pittman had threatened her in the past, and that he had just been released from prison after being convicted of attempted arson at Pinder's residence some ten months earlier. She was naturally afraid for herself and her children, and wanted to know whether it would be safe for her to return to work that evening. Officer Johnson assured her that Pittman would be locked up overnight. He further indicated that Pinder had to wait until the next day to swear out a warrant against Pittman because a county commissioner would not be available to hear the charges before morning. Based on these assurances, Pinder returned to work.

That same evening, Johnson brought Pittman before Dorchester County Commissioner George Ames, Jr. for an initial appearance. Johnson only charged Pittman with trespassing and malicious destruction of property having a value of less than three hundred dollars, both of which are misdemeanor offenses. Consequently, Ames simply released Pittman on his own recognizance and warned him to stay away from Pinder's home.

Pittman did not heed this warning. Upon his release, he returned to Pinder's house and set fire to it. Pinder was still at work, but her three children were home asleep and died of smoke inhalation. Pittman was later arrested and charged with first degree murder. He was convicted and is currently serving three life sentences without possibility of parole.

Pinder brought this action for herself and for the estates of her three children, seeking damages under 42 U.S.C. § 1983 and 42 U.S.C. § 1985, as well as state law theories, against the Commissioners of Cambridge and Officer Johnson. She alleged, inter alia, that defendants had violated their affirmative duty to protect her and her children, thereby depriving them of their constitutional right to due process under the Fourteenth Amendment. Defendant Johnson moved for summary judgment, arguing that he had no constitutionally-imposed affirmative duty to protect the Pinders and that he was shielded from liability by the doctrine of qualified immunity. The district court, however, refused to dismiss plaintiff's due process claim, finding that Officer Johnson was not entitled to qualified immunity. Defendant brought an interlocutory appeal under Mitchell v. Forsyth, 472 U.S. 511, 105 S.Ct. 2806, 86 L.Ed.2d 411 (1985). A divided panel of this court affirmed, finding that Pinder had stated a cognizable substantive due process claim and that Johnson did not have a valid immunity defense. Pinder v. Johnson, 33 F.3d 368 (4th Cir. 1994). We granted rehearing en banc, and now reverse the judgment of the district court.

II.

The basic principles of qualified immunity are well settled. The purpose of a qualified immunity defense under § 1983 is to limit the deleterious effects that the risks of civil liability would otherwise have on the operations of government. See Anderson v. Creighton, 483 U.S. 635, 638, 107 S.Ct. 3034, 3038, 97 L.Ed.2d 523 (1987); Swanson v. Powers, 937 F.2d 965, 967 (4th Cir. 1991), cert. denied, 502 U.S. 1031, 112 S.Ct. 871, 116 L.Ed.2d 777 (1992). Discretionary decisions by government actors inevitably impact the lives of private individuals, sometimes with harmful effects. Moreover, such decisions are inescapably imperfect. Especially in the context of police work, decisions must be made in an atmosphere of great uncertainty. Holding police officers liable in hindsight for every injurious consequence of their actions would paralyze the functions of law enforcement. Torchinsky v. Siwinski, 942 F.2d 257, 260 (4th Cir. 1991). Qualified immunity thus allows officials the freedom to exercise fair judgment, protecting "all but the plainly incompetent or those who knowingly violate the law." Malley v. Briggs, 475 U.S. 335, 341, 106 S.Ct. 1092, 1096, 89 L.Ed.2d 271 (1986).

Qualified immunity under § 1983 shields officials from civil liability unless their actions violated "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). The linchpin of qualified immunity is objective reasonableness. Anderson, 483 U.S. at 639, 107 S.Ct. at 3038-39; Rowland v. Perry, 41 F.3d 167, 172-73 (4th Cir. 1994); Mitchell v. Rice, 954 F.2d 187, 190 (4th Cir.), cert. denied, ___ U.S. ___, 113 S.Ct. 299, 121 L.Ed.2d 222 (1992). So long as the officer's actions, viewed from the perspective of the officer at the time, can be seen within the range of reasonableness, then no liability will attach. Slattery v. Rizzo, 939 F.2d 213, 216 (4th Cir. 1991).

Important to this reasonableness inquiry is whether the rights alleged to have been violated were clearly established at the time of the challenged actions. Harlow, 457 U.S. at 818, 102 S. Ct. at 2738. If the law supporting the allegedly violated rights was not clearly established, then immunity must lie. Anderson, 483 U.S. at 640, 107 S.Ct. at 3039; Tarantino v. Baker, 825 F.2d 772, 774 (4th Cir. 1987). Where the law is clearly established, and where no reasonable officer could believe he was acting in accordance with it, qualified immunity will not attach. The purpose of this doctrine is to ensure that police officers and other government actors have notice of the extent of constitutional restrictions on their behavior. Davis v. Scherer, 468 U.S. 183, 195, 104 S.Ct. 3012, 3019-20, 82 L.Ed.2d 139 (1984). Thus, qualified immunity prevents officials from being blindsided by liability derived from newly invented rights or new, unforeseen applications of pre-existing rights. In short, officials cannot be held to have violated rights of which they could not have known. Gooden v. Howard County, 954 F.2d 960, 968 (4th Cir. 1992) (en banc).

Here, the question is simply whether the due process right Pinder claims was clearly established at the time of her dealings with Johnson. This inquiry depends upon an assessment of the settled law at the time, not the law as it currently exists. DiMeglio v. Haines, 45 F.3d 790, 794 (4th Cir. 1995); Akers v. Caperton, 998 F.2d 220, 227 (4th Cir. 1993). Also, the rights Pinder asserts must have been clearly established in a particularized and relevant sense, not merely as an overarching entitlement to due process. Anderson, 483 U.S. at 640, 107 S.Ct. at 3039; Beardsley v. Webb, 30 F.3d 524, 530 (4th Cir. 1994). It is important not to be over-specific — there need not be a prior case directly on all fours with the facts presented to the official — but "in light of the pre-existing law the unlawfulness" of Johnson's conduct must have been "apparent." Anderson, 483 U.S. at 640, 107 S.Ct. at 3039.

III.

Pinder can point to no clearly established law supporting her claim at the time of the alleged violation. Pinder's claim is that Officer Johnson deprived her and her children of their due process rights by failing to protect them from the violent actions of Pittman. Eighteen days before the events giving rise to this action, the Supreme Court handed down its decision in DeShaney v. Winnebago County Department of Social Services, 489 U.S. 189, 109 S.Ct. 998, 103 L.Ed.2d 249 (1989), which squarely rejected liability under 42 U.S.C. § 1983 based on an affirmative duty theory.

A.

The facts in DeShaney were as poignant as those in this case. There, the Winnebago County Department of Social Services (DSS) received a number of reports that a young boy, Joshua DeShaney, was being abused by his father. DeShaney, 489 U.S. at 192-93, 109 S.Ct. at 1001-02. As this abuse went on, several DSS workers personally observed the injuries that had been inflicted on Joshua. They knew firsthand of the threat to the boy's safety, yet they failed to remove him from his father's custody or otherwise protect him from abuse. Ultimately, Joshua's father beat him so violently that the boy suffered serious brain damage. Id. at 193, 109 S.Ct. at 1001-02. Joshua's mother brought a § 1983 action on his behalf, arguing that the County and its employees had deprived Joshua of his liberty interests without due process by failing to provide adequate protection against his father's violent acts. Id. at 195.

Despite natural sympathy for the plaintiff, the Court held that there was no § 1983 liability under these circumstances. It noted that the Due Process Clause of the Fourteenth Amendment does not require governmental actors to affirmatively protect life, liberty, or property against intrusion by private third parties. Id.; see also Lindsey v. Normet, 405 U.S. 56, 74, 92 S. Ct. 862, 874, 31 L.Ed.2d 36 (1972). Instead, the Due Process Clause works only as a negative prohibition on state action. "Its purpose was to protect the people from the State, not to ensure that the State protected them from each other." DeShaney, 489 U.S. at 196, 109 S.Ct. at 1003. This view is consistent with our general conception of the Constitution as a document of negative restraints, not positive entitlements. See Jackson v. City of Joliet, 715 F.2d 1200, 1203 (7th Cir. 1983), cert. denied, 465 U.S. 1049, 104 S.Ct. 1325, 79 L.Ed.2d 720 (1984). The DeShaney Court concluded that:

[i]f the Due Process Clause does not require the State to provide its citizens with particular protective services, it follows that the State cannot be held liable under the Clause for injuries that could have been averted had it chosen to provide them. As a general matter, then, we conclude that a State's failure to protect an individual against private violence simply does not constitute a violation of the Due Process Clause.

489 U.S. at 196-97, 109 S.Ct. at 1003-04 (footnotes omitted).

The affirmative duty of protection that the Supreme Court rejected in DeShaney is precisely the duty Pinder relies on in this case. Joshua's mother wanted the state to be held liable for its lack of action, for merely standing by when it could have acted to prevent a tragedy. Likewise, Pinder argues Johnson could have, and thus should have, acted to prevent Pittman's crimes. DeShaney makes clear, however, that no affirmative duty was clearly established in these circumstances.

B.

The DeShaney Court did indicate that an affirmative duty to protect may arise when the state restrains persons from acting on their own behalf Id. at 199-200; see also Revere v. Massachusetts General Hospital, 463 U.S. 239, 244, 103 S.Ct. 2979, 2983, 77 L.Ed.2d 605 (1983); Youngberg v. Romeo, 457 U.S. 307, 317, 102 S. Ct. 2452, 2458-59, 73 L.Ed.2d 28 (1982). The Court explained that "when the State by the affirmative exercise of its power so restrains an individual's liberty that it renders him unable to care for himself, and at the same time fails to provide for his basic human needs . . . it transgresses the substantive limits on state action set by the Eighth Amendment and the Due Process Clause." DeShaney, 489 U.S. at 200, 109 S.Ct. at 1005.

The specific source of an affirmative duty to protect, the Court emphasized, is the custodial nature of a "special relationship." DeShaney reasoned that "[t]he affirmative duty to protect arises not from the State's knowledge of the individual's predicament or from its expressions of intent to help him, but from the limitation which it has imposed on his freedom to act on his own behalf." Id. Some sort of confinement of the injured party — incarceration, institutionalization, or the like — is needed to trigger the affirmative duty. Id. This Court has consistently read DeShaney to require a custodial context before any affirmative duty can arise under the Due Process Clause. See, e.g., Rowland, 41 F.3d at 174-75 (noting that when the state has not restricted one's ability to care for oneself, the rationale for an affirmative duty falls away); Piechowicz v. United States, 885 F.2d 1207, 1215 (4th Cir. 1989) (holding that "substantive due process protects the liberty interests only of persons affirmatively restrained by the United States from acting on their own behalf") (emphasis added).

There was no custodial relationship with the plaintiffs in this case. Neither Johnson nor any other state official had restrained Pinder's freedom to act on her own behalf. Pinder was never incarcerated, arrested, or otherwise restricted in any way. Without any such limitation imposed on her liberty, DeShaney indicates Pinder was due no affirmative constitutional duty of protection from the state, and Johnson would not be charged with liability for the criminal acts of a third party.

C.

Pinder argues, however, that Johnson's explicit promises that Pittman would be incarcerated overnight created the requisite "special relationship." We do not agree. By requiring a custodial context as the condition for an affirmative duty, DeShaney rejected the idea that such a duty can arise solely from an official's awareness of a specific risk or from promises of aid. DeShaney, 489 U.S. at 200, 109 S.Ct. at 1005-06. There, as here, plaintiff alleged that the state knew of the special risk of harm at the hands of a third party. Id. at 197, 109 S.Ct. at 1004. There, as here, plaintiff alleged that the state had "specifically proclaimed, by word and by deed, its intention to protect" the victim. Id. Neither allegation was sufficient to support the existence of an affirmative duty in DeShaney, and the same holds true in this case.

Promises do not create a special relationship — custody does. Unlike custody, a promise of aid does not actually place a person in a dangerous position and then cut off all outside sources of assistance. Promises from state officials can be ignored if the situation seems dire enough, whereas custody cannot be ignored or changed by the persons it affects. It is for this reason that the Supreme Court made custody the crux of the special relationship rule. Lacking the slightest hint of a true "special relationship," Pinder's claim in this case boils down to an insufficient allegation of a failure to act.

We also cannot accept Pinder's attempt to escape the import of DeShaney by characterizing her claim as one of affirmative misconduct by the state in "creating or enhancing" the danger, instead of an omission. She emphasizes the "actions" that Johnson took in making assurances, and in deciding not to charge Pittman with any serious offense. By this measure, every representation by the police and every failure to incarcerate would constitute "affirmative actions," giving rise to civil liability. At some point on the spectrum between action and inaction, the state's conduct may implicate it in the harm caused, but no such point is reached here. It cannot be that the state "commits an affirmative act" or "creates a danger" every time it does anything that makes injury at the hands of a third party more likely. If so, the state would be liable for every crime committed by the prisoners it released. See Martinez v. California, 444 U.S. 277, 284-85, 100 S.Ct. 553, 558-59, 62 L.Ed.2d 481 (1980) (no state action when released prisoner causes injury). No amount of semantics can disguise the fact that the real "affirmative act" here was committed by Pittman, not by Officer Johnson. As was true in DeShaney, the state did not "create" the danger, it simply failed to provide adequate protection from it. In both cases, "[t]he most that can be said of the state functionaries . . . is that they stood by and did nothing when suspicious circumstances dictated a more active role for them." Id. at 203, 109 S.Ct. at 1007. Thus, like DeShaney, Pinder's case is purely an omission claim.

Given the principles laid down by DeShaney, it can hardly be said that Johnson was faced with a clearly established duty to protect Pinder or her children in March of 1989. Indeed, it can be argued that DeShaney established exactly the opposite, i.e., that no such affirmative duty existed because neither Pinder nor her children were confined by the state. At a minimum, Officer Johnson was not on notice that any conduct of his was unconstitutional.

IV.

The lack of any clearly established duty to protect individuals outside of the custodial context is also reflected in the law in the lower federal courts at the time of the events in question. No court had actually found a due process right to protection from third parties based on mere assurances by state officials, while a number of decisions directly or indirectly rejected just such a proposition. Thus, again, the weight of authority confirms the opposite of the conclusion plaintiff seeks to prove, and certainly cannot be said to clearly establish a due process right like the one Pinder asserts here.

The salient issue in the lower courts both before and since DeShaney has been whether the notion of the special relationship is limited to the penal/institutional context or whether it can be extended to other areas of state conduct. A number of pre- DeShaney cases were strict in their definition of the special relationship giving rise to a state's affirmative duty to protect, expressly linking the duty to the fact of custody. E.g. Wideman v. Shallowford Community Hospital Inc., 826 F.2d 1030, 1035-36 (11th Cir. 1987) ("key concept is the exercise of coercion, dominion, or restraint by the state"); Washington v. District of Columbia, 802 F.2d 1478, 1481 (D.C. Cir. 1986) (duty depends on custody); Walker v. Rowe, 791 F.2d 507, 511 (7th Cir.) (duty depends on "constraints the state imposes on private action"), cert. denied, 479 U.S. 994, 107 S.Ct. 597, 93 L.Ed.2d 597 (1986). Several courts in fact concluded that the duty was absolutely limited to those few contexts wherein a person's freedom to act is severely constrained by the state — prisons, mental institutions, and the like. See, e.g., Harpole v. Arkansas Dep't. of Human Servs., 820 F.2d 923, 927 (8th Cir. 1987) (only prisons); Estate of Gilmore v. Buckley, 787 F.2d 714, 722 (1st Cir.) (only those in actual custody or control), cert. denied, 479 U.S. 882, 107 S.Ct. 270, 93 L.Ed.2d 247 (1986). See also McLenagan v. Karnes, 27 F.3d 1002, 1008 n. 9 (4th Cir. 1994), cert. denied, ___ U.S. ___, 115 S.Ct. 581, 130 L.Ed.2d 496 (1994); Walton v. City of Southfield, 995 F.2d 1331, 1337 (6th Cir. 1993); Hilliard v. City and County of Denver, 930 F.2d 1516, 1520 (10th Cir. 1991), cert. denied, 502 U.S. 1013, 112 S. Ct. 656, 116 L.Ed.2d 748 (1991); Fialkowski v. Greenwich Home for Children, Inc., 921 F.2d 459, 465 (3d Cir. 1990); Weller v. Dep't. of Social Servs. for Baltimore, 901 F.2d 387, 392 (4th Cir. 1990); Milburn v. Anne Arundel County Dep't of Social Servs., 871 F.2d 474, 476 (4th Cir.), cert. denied, 493 U.S. 850, 110 S.Ct. 148, 107 L.Ed.2d 106 (1989).

It is true, as the district court noted, that some cases found an "affirmative duty" arising outside the traditional custodial context. See Pinder v. Commissioners of Cambridge, 821 F. Supp. 376, 388-89 (D. Md. 1993) (collecting cases). None of these cases, however, clearly establish the existence of the right Pinder alleges was violated. First, none of these cases found a particularized due process right to affirmative protection based solely on an official's assurances that the danger posed by a third party will be eliminated. All involved some circumstance wherein the state took a much larger and more direct role in "creating" the danger itself. These cases involve a wholly different paradigm than that presented here. When the state itself creates the dangerous situation that resulted in a victim's injury, the absence of a custodial relationship may not be dispositive. In such instances, the state is not merely accused of a failure to act; it becomes much more akin to an actor itself directly causing harm to the injured party. See, e.g., Cornelius v. Town of Highland Lake, 880 F.2d 348, 356 (11th Cir. 1989) (duty when state brought inmates into victim's workplace); Wells v. Walker, 852 F.2d 368, 371 (8th Cir. 1988) (duty when state brought dangerous prisoners to victim's store), cert. denied, 489 U.S. 1012, 109 S.Ct. 1121, 103 L.Ed.2d 184 (1989); Nishiyama v. Dickson County, 814 F.2d 277, 281 (6th Cir. 1987) (duty when state provided unsupervised parolee with squad car). See also Archie v. City of Racine, 847 F.2d 1211, 1223 (7th Cir. 1988) (en banc) (court's broad definition of when duty arises does not mention promises by official as a potential factor), cert. denied, 489 U.S. 1065, 109 S.Ct. 1338, 103 L.Ed.2d 809 (1989). At most, these cases stand for the proposition that state actors may not disclaim liability when they themselves throw others to the lions. See K.H. ex rel. Murphy v. Morgan, 914 F.2d 846, 849 (7th Cir. 1990). They do not, by contrast, entitle persons who rely on promises of aid to some greater degree of protection from lions at large.

Second, several of the cases on which Pinder relies were singled out by the Supreme Court in DeShaney for their overbroad view of special relationships. 489 U.S. at 197-98 n. 4, 109 S. Ct. at 1004 n. 4. In particular, plaintiff relies heavily on the opinion in Jensen v. Conrad, 747 F.2d 185 (4th Cir. 1984), which held that a special relationship can result from 1) legal custody; 2) express promises of protection; or 3) state knowledge of the victim's plight. 747 F.2d at 194-95 n. 11. The Jensen court believed that affirmative duties arose not because the state limited freedom of personal action but because the state "selected an individual from the public at large and placed him in a position of danger." Id. at 194. The DeShaney opinion cited this case, and several others like it, as support for the plaintiff's argument that the state had an affirmative duty because it had "actually undertaken" to protect Joshua. 489 U.S. at 197-98 n. 4, 109 S.Ct. at 1004 n. 4. The Supreme Court then said in no uncertain terms, "[w]e reject this argument." Id. at 198. There can be no doubt, therefore, that Jensen and its companion cases arguing for a broad conception of the special relationship afford no basis for vitiating Johnson's immunity defense.

Finally, a number of the cases plaintiff relies upon were decided months or years after Johnson's dealings with Pinder and so are not relevant to our assessment of the clearly established law at the time. See Gregory v. City of Rogers, 974 F.2d 1006 (8th Cir. 1992), cert. denied, ___ U.S. ___, 113 S.Ct. 1265, 122 L.Ed.2d 661 (1993); Freeman v. Ferguson, 911 F.2d 52 (8th Cir. 1990); Wood v. Ostrander, 879 F.2d 583 (9th Cir. 1989), cert. denied, 498 U.S. 938, 111 S.Ct. 341, 112 L.Ed.2d 305 (1990). We do not agree with Pinder that these cases premise civil liability on official promises — even if they did, however, there is no way Officer Johnson could have been aware of them. See DiMeglio, 45 F.3d at 806. Indeed, this case is a quintessential example of the kind of circumstance where qualified immunity forecloses the need for officials to guess about such future developments in constitutional law. See Swanson v. Powers, 937 F.2d at 968 (citing Lum v. Jensen, 876 F.2d 1385, 1389 (9th Cir. 1989)). The courts have been careful not to add legal prognostication to the already lengthy list of police officer responsibilities. "To expect Defendants to resolve what reasonable jurists have long debated . . . is to impose burdens and expectations well beyond their reasonable capacities." Hodge v. Jones, 31 F.3d 157, 167 (4th Cir. 1994), cert. denied, ___ U.S. ___, 115 S.Ct. 581, 130 L.Ed.2d 496 (1994).

The extensive debate provoked by this case should be proof enough that the law in this area was anything but clearly established at the time Officer Johnson gave assurances to Pinder. See Stoneking v. Bradford Area School Dist., 882 F.2d 720, 724 (3d Cir. 1989) ( Stoneking II) (declining to rest decision on an affirmative duty because of "the uncertainty of the law in this respect"), cert. denied, 493 U.S. 1044, 110 S. Ct. 840, 107 L.Ed.2d 835 (1990). To impose liability in the absence of a clearly established constitutional duty is to invite litigation over a limitless array of official acts.

V.

The recitation of the case law that defeats Pinder's claim cannot be divorced from the rationale underlying it. There are good reasons why the constitutional right to protection sought by Pinder was not clearly established by the courts. As the First Circuit noted in a similar case, "[e]normous economic consequences could follow from the reading of the Fourteenth Amendment that plaintiff here urges." Estate of Gilmore, 787 F.2d at 722. The consequences, however, are not just economic, and their gravity indicates why the right Pinder asserts was never clearly established.

The recognition of a broad constitutional right to affirmative protection from the state would be the first step down the slippery slope of liability. Such a right potentially would be implicated in nearly every instance where a private actor inflicts injuries that the state could have prevented. See id. at 723. Every time a police officer incorrectly decided it was not necessary to intervene in a domestic dispute, the victims of the ensuing violence could bring a § 1983 action. Every time a parolee committed a criminal act, the victims could argue the state had an affirmative duty to keep the prisoner incarcerated. Indeed, victims of virtually every crime could plausibly argue that if the authorities had done their job, they would not have suffered their loss. Broad affirmative duties thus provide a fertile bed for § 1983 litigation, and the resultant governmental liability would wholly defeat the purposes of qualified immunity.

If the right Pinder asserts were ever clearly established, it would entail other significant consequences. A general obligation of the state to protect private citizens, whether broadly or narrowly conceived, effectively makes law enforcement officials constitutional guarantors of the conduct of others. Such a system would engender a variety of perverse incentives. Local officials faced with ambiguous circumstances would be forced to inject themselves into private affairs to foreclose the complaint that they should have done more. Rather than let a suspect go free, the temptation would be to make a premature arrest to forestall civil liability. In the same way, if promises could override a qualified immunity defense, police would quickly learn never to reassure, even in situations where such assurances might be the best course of action.

It is no solution to say that such a right to affirmative protection has its inherent limitations. It is no answer to contend that the duty here was created only by Johnson's promise and Pinder's reliance on that promise, and is limited by Johnson's awareness of the risk. Such "limitations" are no barrier to increased lawsuits. There are endless opportunities for disagreements over the exact nature of an official's promise, the intent behind it, the degree of the reliance, the causal link between the promise and the injury, and so on. Similarly, the extent of the state's affirmative duty to protect and the degree of the state's awareness of the risk are also subjects that would tie up state and local officials in endless federal litigation.

The Supreme Court has reacted to the specter of such extensive local liability by removing categories of claims from the scope of due process recovery. Liability for simple negligence is one such category. Daniels v. Williams, 474 U.S. 327, 106 S.Ct. 662, 88 L.Ed.2d 662 (1986). Claims based on only reputational harm are a second example. Paul v. Davis, 424 U.S. 693, 702, 96 S.Ct. 1155, 1161, 47 L.Ed.2d 405 (1976). Claims involving omissions, or the failure to protect, are a third area held to be non-actionable. DeShaney, 489 U.S. at 202, 109 S.Ct. at 1006-07. Pinder's claims notwithstanding, it makes sense to see DeShaney as a bright-line decision, in which the Court saw in the admittedly sympathetic case the first step on a long, litigious journey.

In cases like this, it is always easy to second-guess. Tragic circumstances only sharpen our hindsight, and it is tempting to express our sense of outrage at the failure of Officer Johnson to protect Pinder's children from Pittman's villainy. The Supreme Court in DeShaney specifically rejected the "shocks the conscience" test of Rochin v. California, 342 U.S. 165, 172, 72 S.Ct. 205, 209, 96 L.Ed. 183 (1952) as a basis for imposing § 1983 liability in the affirmative duty context, however. DeShaney, 489 U.S. at 197-98, 109 S.Ct. at 1004-05. We cannot simply ignore the lack of any clearly established constitutional duty to protect and the concomitant immunity from civil liability. Hard cases can make bad law, and it is to protect against that possibility that police officers possess the defense of qualified immunity.

VI.

For the foregoing reasons, the judgment of the district court denying qualified immunity to Officer Johnson is

REVERSED.
