Federal Constitutional Excessive-Force Standard

Overview

There is no single federal statute that comprehensively defines when a state or local police officer may use force. For most police encounters, the controlling federal standard comes from the Fourth Amendment’s prohibition on unreasonable seizures, as interpreted by the U.S. Supreme Court. The basic rule is that police force used to seize a person must be objectively reasonable under the totality of the circumstances, judged from the perspective of a reasonable officer on the scene and based on the facts known to the officer at the time.

The modern framework is built principally from (Tennessee v. Garner, 1985), which establishes important limits on deadly force; (Graham v. Connor, n.d.), which establishes the general objective-reasonableness framework; and (Barnes v. Felix, 2025), which confirms that the inquiry requires consideration of all relevant circumstances and cannot be confined to the final seconds immediately preceding the use of force. The constitutional standard is a floor, not necessarily a model police policy, and departments may–and commonly do–adopt rules that are more restrictive than what the Constitution minimally requires.

Legal Architecture

Fourth Amendment: stops, arrests, and other seizures

When force is used during an investigatory stop, arrest, attempted arrest, or other seizure of a free person, the claim is ordinarily analyzed under the Fourth Amendment. Graham v. Connor rejected the use of a generalized substantive-due-process test for this setting and held that excessive-force claims arising from arrests or investigatory stops must be analyzed through the Fourth Amendment’s reasonableness requirement.

Fourteenth Amendment: pretrial detainees

Once a person is detained pending trial, the constitutional source changes. In (Kingsley v. Hendrickson, 2015), the Supreme Court held that a pretrial detainee alleging excessive force under the Fourteenth Amendment need show that the force purposely or knowingly used was objectively unreasonable, and the detainee need not prove that the officer subjectively recognized that the force was excessive.

Eighth Amendment: sentenced prisoners

Force against a convicted prisoner is generally governed by the Eighth Amendment’s prohibition on cruel and unusual punishment. That standard differs from Graham and ordinarily focuses on whether force was applied in a good-faith effort to maintain or restore discipline or instead maliciously and sadistically to cause harm. Because the Lab focuses primarily on police encounters before incarceration, this backgrounder concentrates on the Fourth Amendment.

42 U.S.C. § 1983

For state and local officers, the most common civil vehicle for enforcing federal constitutional rights is 42 U.S.C. § 1983. Section 1983 does not itself create the excessive-force standard; rather, it provides a civil cause of action against persons acting under color of state law who deprive another person of rights secured by the Constitution or federal law. The Fourth Amendment is the source of the right, and § 1983 is the principal civil enforcement mechanism against state and local actors.

18 U.S.C. § 242

Excessive force can also lead to federal criminal prosecution under 18 U.S.C. § 242, which criminalizes willful deprivation of constitutional rights under color of law. The criminal standard is materially different from ordinary civil liability because the government must prove willfulness beyond a reasonable doubt, meaning a force incident can violate the Constitution without necessarily satisfying the criminal mens rea required by § 242.

The Core Fourth Amendment Standard

Objective reasonableness

Graham v. Connor makes the inquiry objective. The central question is not what the officer personally intended but whether the force would have been objectively reasonable from the perspective of a reasonable officer on the scene, considering the circumstances confronting the officer. The Court instructed judges to avoid evaluating force with the benefit of 20/20 hindsight, while also making clear that “split-second decision” language does not create automatic deference whenever an officer says a situation developed rapidly; the reasonableness inquiry remains fact-specific.

The Graham factors

Graham identified three recurring considerations: the severity of the crime at issue, whether the subject poses an immediate threat to the safety of officers or others, and whether the subject is actively resisting arrest or attempting to evade arrest by flight. These factors are not an exhaustive checklist, and courts regularly consider other circumstances where relevant. Depending on the case, those may include:

• whether the person was armed;
• what officers knew about the weapon;
• distance;
• movement;
• warnings;
• number of officers;
• availability of cover;
• whether the person was contained;
• duration of the encounter;
• whether force continued after control was achieved;
• mental or behavioral crisis;
• whether officers attempted to temper the force used;
• and events leading up to the final use of force.

Totality of the circumstances

The inquiry is holistic, and the Supreme Court has repeatedly rejected rigid formulas. In (Scott v. Harris, 2007), the Court emphasized that Fourth Amendment force cases require balancing the nature of the intrusion against the governmental interests at stake and resisted converting Garner into a mechanical checklist applicable to every form of deadly force. The governing question remains reasonableness under the actual circumstances.

Deadly Force

Tennessee v. Garner

(Tennessee v. Garner, 1985), rejected the old rule that police could use deadly force simply to prevent the escape of any fleeing felony suspect. The Court held that deadly force may not be used against an apparently unarmed, nondangerous fleeing person merely because the person might escape. Where deadly force is used to prevent escape, the central Garner principle is that the officer must have probable cause to believe the person poses a significant threat of death or serious physical injury to the officer or others. The Court also stated that, where feasible, a warning should precede deadly force.

Deadly force is not limited to firearms

The Constitution does not classify force solely by equipment label. An action can amount to deadly force where the manner of use creates a substantial risk of causing death or serious bodily injury. For example, Scott v. Harris involved an officer intentionally terminating a high-speed vehicle pursuit by striking the fleeing vehicle, and the Supreme Court evaluated the action through Fourth Amendment balancing rather than treating the vehicle maneuver as constitutionally distinct merely because no firearm was used.

Continued force must remain justified

Reasonableness can change as circumstances change. In (Plumhoff v. Rickard, 2014), the Court held that officers acted reasonably in firing multiple shots to terminate a dangerous high-speed chase. Importantly, the Court did not establish that once deadly force becomes justified, unlimited continuation is automatically lawful; the justification depends on whether the threat requiring the force remains present.

Leading Decisions

The decisions below are presented chronologically to show the development of the federal excessive-force standard over time.

Tennessee v. Garner

Rule: Deadly force may not be used solely to prevent the escape of an apparently nondangerous fleeing felony suspect. Deadly force can be reasonable where the officer has probable cause to believe the suspect poses a significant threat of death or serious physical injury.

Importance: Establishes the modern constitutional limit on police deadly force and confirms that deadly force is a Fourth Amendment seizure.

Policy significance: Threat–not felony classification alone–is central. Warning is relevant where feasible.

---

Graham v. Connor

Rule: Force used during an arrest, stop, or seizure is judged under the Fourth Amendment’s objective-reasonableness standard.

Importance: The foundational general excessive-force decision.

Core factors: Severity of crime, immediate threat, resistance, and flight.

Policy significance: The analysis turns on what a reasonable officer would do under the circumstances, not an officer’s subjective good or bad motive.

---

Scott v. Harris

Rule: Fourth Amendment force analysis is not governed by a rigid mechanical test. Courts balance the intrusion against the governmental interest under the actual circumstances.

Facts of significance: A high-speed pursuit posed a substantial and immediate danger to the public; an officer intentionally forced the fleeing vehicle off the road.

Policy significance: Serious danger to third parties can substantially alter the reasonableness balance.

---

Plumhoff v. Rickard

Rule: Officers did not violate the Fourth Amendment by using deadly firearm force to terminate a dangerous high-speed chase where the threat to public safety remained ongoing.

Policy significance: Courts examine the entire threat context, not merely the instant of individual shots.

Barnes later used Plumhoff as an example of why preceding events can inform the reasonableness of the final use of force.

---

County of Los Angeles v. Mendez

Rule: The Ninth Circuit’s former provocation rule was invalid: that rule had allowed an otherwise reasonable use of force to become actionable because officers committed a separate Fourth Amendment violation that foreseeably led to the confrontation, and the Supreme Court held that distinct Fourth Amendment claims must not be conflated.

What Mendez did not fully resolve: The Court did not definitively settle every question about how an officer’s earlier tactical conduct may bear on the ordinary Graham totality-of-the-circumstances analysis. That unresolved issue became increasingly important and remains significant after Barnes.

---

Torres v. Madrid

Rule: Application of physical force to a person’s body with intent to restrain can constitute a Fourth Amendment seizure even if the person escapes or does not submit.

Importance: A shooting may be a seizure even where the person continues fleeing afterward. The existence of a seizure is only the first step; the force must still be assessed for reasonableness.

---

Lombardo v. City of St. Louis, 594 U.S. 464 (2021) (per curiam)

Rule / significance: Courts must give careful attention to all relevant facts when evaluating restraint force; the Supreme Court faulted the lower court for failing to adequately consider circumstances including:

• duration of restraint;
• the subject’s handcuffed and leg-shackled condition;
• pressure applied while prone;
• known risks of prone restraint;
• number of officers present; and
• whether the subject’s movements may have reflected oxygen deprivation rather than resistance.

Policy significance: “Resistance” cannot be viewed in isolation from the physical condition of the person and the manner and duration of restraint.

---

Barnes v. Felix

Rule: Courts may not evaluate a police shooting using a rule that considers only the precise moment of threat. The Fourth Amendment requires consideration of all relevant circumstances, including facts and events leading up to the climactic moment. The Court unanimously rejected the Fifth Circuit’s narrow moment-of-threat doctrine.

Key principle:

The totality-of-the-circumstances inquiry has no artificial time limit.

Earlier facts may make later conduct appear:

• more threatening;
• less threatening;
• ambiguous;
• or innocuous.

Important limit: Barnes expressly did not resolve the distinct question of whether and how an officer’s own creation of a dangerous situation should affect the reasonableness analysis. That issue remains a major area of circuit-level development.

Related Constitutional Standard

Kingsley v. Hendrickson

Rule: A pretrial detainee alleging excessive force under the Fourteenth Amendment need show that the force purposely or knowingly used was objectively unreasonable, not that the officer subjectively knew it was excessive.

Importance: Kingsley is not part of the ordinary Fourth Amendment police-force sequence, but it is an important adjacent excessive-force standard because constitutional analysis changes once a person is a pretrial detainee.

Recent Circuit Application: Spencer v. Glaser (4th Cir. 2026)

Spencer v. Glaser, No. 25-1425, 2026 WL 2235303 (4th Cir. Aug. 4, 2026), is an important early application of Barnes v. Felix to a multi-shot police shooting involving an edged weapon. Deputies responded to a medical-assistance call involving Sylvester Selby, who was bleeding from a chest wound. Selby emerged from a residence holding a kitchen knife and an apple. After repeated commands to drop the knife, he moved down the porch steps toward the deputies while still armed. Deputy Edward Glaser fired once. Selby fell, dropped the knife and apple, and remained on the ground for approximately 12 seconds. He then attempted to rise and moved toward Deputy Glaser, who fired two additional shots.

The estate challenged the second and third shots, arguing in substance that the threat supporting the first shot had ended because Selby was no longer holding the knife. The Fourth Circuit rejected an analysis that treated the later shots as though the encounter restarted after the knife was dropped. Relying expressly on Barnes, the court explained that earlier facts and circumstances may bear on how a reasonable officer would have understood and responded to later ones. The court held that Selby’s earlier knife-wielding advance remained relevant to how a reasonable officer could interpret his renewed movement seconds later, and the body-worn-camera footage showed that Selby lunged toward Glaser before the second and third shots.

Multiple shots must be separately justified–but not analyzed in isolation

Spencer is useful because it reconciles two propositions that can otherwise appear inconsistent: each separate application of deadly force must remain justified when it occurs, and the officer is not required to disregard what happened seconds earlier when assessing a renewed threat. Thus, the fact that an initial shooting was reasonable does not create an unlimited continuing licence to fire–if the threat genuinely ends, the justification for deadly force may end as well–but a temporary change in circumstances does not require the officer, or the reviewing court, to treat later movement as though the prior armed confrontation never occurred.

Barnes can favour either party

Spencer is also an important corrective to treating Barnes solely as a plaintiff-favouring decision, because a broader temporal frame may reveal unnecessary escalation, reckless positioning, failure to use available time or cover, or other pre-force decisions that weigh against the officer. But the same broader frame may show:

• recent weapon possession;
• previous threatening movement;
• repeated noncompliance;
• prior attacks;
• or facts that make later ambiguous conduct appear more threatening.

The totality-of-the-circumstances requirement is therefore context expanding, not outcome directional.

Body-worn-camera significance

Spencer is independently important for its treatment of body-worn-camera footage, and the Fourth Circuit permitted consideration of footage incorporated into the complaint at the Rule 12(b)(6) stage where the recording blatantly contradicted factual allegations. The court also emphasized the limits of that principle. Video may clearly establish where a person moved, whether an object remained in hand, or whether a person moved toward an officer, but it may not necessarily establish why an officer stumbled, what a person intended, what the officer subjectively perceived, or facts outside the camera’s visual and auditory limitations. That distinction is particularly important for use-of-force research: video can contradict factual description without becoming a complete substitute for human perception or contextual interpretation.

Ventura v. Rutledge: Edged Weapon, Third-Party Threat, Warnings, and Qualified Immunity

Ventura v. Rutledge, 978 F.3d 1088 (9th Cir. 2020), is a useful Ninth Circuit edged-weapon case because it brings together several recurring factors:

• a recently reported domestic assault;
• a third party located in the subject’s path;
• a drawn knife;
• repeated commands to stop;
• an explicit warning that the officer would shoot;
• and distance to the potential victim.

Officer Rutledge responded to a violent domestic-disturbance call. Omar Ventura had reportedly assaulted both Martha Andrade and his mother and damaged Andrade’s vehicle. While Rutledge was speaking with Andrade, Ventura returned. According to the undisputed facts identified by the Ninth Circuit, Ventura:

• continued toward Andrade;
• drew a knife;
• ignored repeated commands to stop;
• continued advancing after Rutledge warned, “Stop or I’ll shoot”;
• and came within approximately 10–15 feet of Andrade before Rutledge fired two fatal shots.

The court decided only qualified immunity

The Ninth Circuit did not decide whether the shooting was constitutionally reasonable on the merits. It expressly addressed only the second qualified-immunity question: whether the asserted Fourth Amendment right was clearly established in December 2015. The court held that it was not clearly established that shooting under those circumstances constituted excessive force. That distinction is critical: Ventura is authority about clearly established law, not a categorical holding that every shooting involving a knife at 10–15 feet is constitutionally reasonable.

Third-party threat mattered

The court repeatedly emphasized that Ventura was advancing toward Andrade, a woman whom he had reportedly just assaulted. This distinguishes the case from encounters where the edged weapon is directed only toward the subject, the person is stationary, no civilian is within reach, or the person is separated from third parties by a meaningful barrier. The third-party risk was therefore not incidental; it was part of the factual combination that prevented earlier cases from clearly establishing unlawfulness.

Warnings and commands mattered

Rutledge gave multiple commands to stop and an explicit warning that she would shoot. The court treated Ventura’s continued advance despite those commands and warning as part of the specific qualified-immunity context. The case therefore reinforces that a research record should distinguish:

• command given;
• force warning given;
• opportunity to respond;
• and continued movement toward a threatened third party.

Distance must specify distance to whom

Ventura is also useful methodologically because a single “distance” variable can be misleading. The published opinion records that Ventura had reached approximately 10–15 feet from Andrade when Rutledge fired. Secondary reporting states that Rutledge was approximately 10 yards from Ventura when she gave the warning. Those are different distances answering different tactical questions. For edged-weapon research, distance should therefore be recorded separately where possible as:

• subject → officer;
• subject → civilian / intended victim;
• subject → weapon;
• officer → cover;
• and subject → cover/barrier.

A statement such as “the subject was 15 feet away” is incomplete without identifying the reference point.

Comparison with Kisela

The Ninth Circuit relied heavily on Kisela v. Hughes, where the Supreme Court held that existing precedent had not clearly established the unlawfulness of shooting a knife-holding woman who was near another person and ignored commands to drop the knife. The Ventura panel concluded that Ventura presented at least as much apparent danger because he was approaching a person he had reportedly just assaulted, he was holding a knife, he ignored repeated commands, and he continued after an explicit firearm warning.

Research-library significance

Ventura should be coded as:

• edged weapon: yes;
• third-party threat: yes;
• recent assault on third party: reported;
• weapon drawn: yes;
• commands: repeated stop commands;
• force warning: yes;
• distance to third party at shooting: approximately 10–15 feet;
• merits: not decided;
• qualified immunity: granted;
• clearly established: no.

It is a particularly strong example of why the Lab should never code qualified immunity granted as equivalent to force held reasonable.

Circuit Variation After Barnes v. Felix

What Barnes resolved

Before 2025, circuits differed significantly over how much of the encounter courts could examine, and the Fifth Circuit’s “moment-of-threat” doctrine confined analysis to the narrow period in which the officer perceived the threat immediately prompting deadly force. Barnes rejected that framework, and courts nationwide must now consider all relevant circumstances; they may not impose chronological blinders that exclude earlier portions of the encounter merely because they preceded the final threat.

What Barnes did not resolve

The major remaining question is not whether earlier events may be considered–they may–but what legal significance should be given to an officer’s earlier tactical decisions when those decisions helped create or intensify the danger that later led to force. This is often described as:

• officer-created jeopardy;
• officer-created need for force;
• pre-seizure conduct;
• tactical recklessness;
• or escalation by police.

Tenth Circuit: relatively developed officer-created-need doctrine

The Tenth Circuit has one of the clearest doctrines permitting consideration of officers’ own earlier conduct, and its cases have held that force may be unreasonable where an officer’s reckless or deliberate conduct is immediately connected to–and unreasonably creates–the need to use deadly force. Decisions including Allen v. Muskogee, Pauly v. White, and Estate of Ceballos v. Husk developed this approach, and the Tenth Circuit continued applying the doctrine after Mendez, reasoning that it evaluates the ordinary Graham reasonableness of the force encounter rather than resurrecting the Ninth Circuit’s invalid provocation rule. This remains a significant doctrinal difference among circuits.

Ninth Circuit: broad totality, but no Mendez provocation rule

The Ninth Circuit can consider relevant pre-shooting conduct as part of the totality of circumstances, including matters such as:

• warnings;
• availability of less intrusive alternatives in some contexts;
• apparent mental illness;
• tactical approach;
• and the sequence immediately preceding force.

Mendez eliminated the former Ninth Circuit rule under which a separate constitutional violation could automatically convert an otherwise reasonable shooting into excessive force, and the modern inquiry must remain tied to the reasonableness of the seizure itself.

Other circuits

Other circuits historically varied in how strongly they separated the officer’s tactical decisions leading to the threat from the threat confronting the officer at the instant force was used. After Barnes, they cannot categorically disregard earlier relevant events, but courts may still differ in:

• how much weight they give tactical mistakes;
• whether negligent conduct is legally meaningful;
• whether only reckless or deliberate escalation matters;
• how closely prior conduct must be connected to the eventual force;
• how warnings affect the analysis;
• and how mental or behavioral crisis is incorporated into reasonableness.

This means Barnes reduces one major circuit split without eliminating regional variation in application.

Qualified Immunity and Remedies

Constitutional violation and liability are separate questions

A court may conclude that force violated the Fourth Amendment and still determine that an individual officer cannot be held personally liable for damages because of qualified immunity. Qualified immunity asks, in general terms, whether the officer violated a federal constitutional right and, if so, whether that right was clearly established at the time of the conduct. The Supreme Court has repeatedly emphasized that clearly established law ordinarily must be framed with sufficient factual specificity, with the result that whether force was unconstitutional and whether a particular officer can be personally liable for damages are related but separate questions. This distinction is essential when interpreting appellate cases, because a case resolved on qualified immunity may not necessarily hold that the underlying force was constitutionally reasonable.

Municipal liability

A city or county is not automatically liable under § 1983 merely because one of its employees violated the Constitution. Under Monell v. Department of Social Services, municipal liability ordinarily requires that the constitutional injury result from an official policy, custom, practice, or other qualifying municipal action. Failure-to-train theories have additional demanding requirements.

Federal officers

Section 1983 generally addresses state and local action, and civil damages actions directly against federal officers arise under a different and increasingly restricted body of law associated with Bivens v. Six Unknown Named Agents. Recent Supreme Court decisions have sharply limited expansion of Bivens remedies into new contexts, meaning the Fourth Amendment standard and the availability of a damages remedy against a federal officer should not be treated as the same question.

Policy Implications

1. The constitutional review should no longer begin only at the trigger pull

After Barnes, department training and critical-incident review should not artificially isolate the last second of an encounter. Relevant context may include:

• why officers initiated contact;
• information available before contact;
• warnings;
• changes in threat level;
• positioning;
• attempted disengagement;
• containment;
• communication;
• subject conduct;
• and how the encounter developed over time.

That does not mean every tactical mistake makes later force unconstitutional, but it does mean earlier events cannot be excluded simply because they happened before the final threat.

2. Threat assessment remains central

Among the Graham factors, immediate threat to officers or others is often the most consequential in serious-force cases. Policies should therefore require articulation of what the threat actually was, not merely labels such as:

• “noncompliant”;
• “armed”;
• “agitated”;
• or “resisting.”

Useful articulation includes:

• what the person was doing;
• distance;
• movement;
• access to others;
• weapon capability;
• barriers;
• warnings;
• and what officers reasonably believed would happen if they did not act.

3. Policy can be stricter than constitutional law

The Fourth Amendment asks whether force was constitutionally reasonable, and department policy can separately require necessity, proportionality, de-escalation, warnings, tactical repositioning, supervisor approval, less-lethal consideration, duty to intervene, medical aid, or restrictions on particular tactics. A policy violation does not automatically establish a constitutional violation, and compliance with department policy does not automatically prove constitutional reasonableness.

4. DOJ policy illustrates the distinction

The current Department of Justice use-of-force policy expressly goes beyond simply reciting Graham. DOJ policy states that officers may use only objectively reasonable force and only where no reasonably effective, safe, and feasible alternative appears to exist. For deadly force, DOJ requires a reasonable belief that the subject poses an imminent danger of death or serious physical injury. The policy also requires or emphasizes:

• de-escalation where objectively feasible and safe;
• warning before deadly force where feasible;
• a duty to intervene;
• a duty to request or render medical aid;
• and recurring force training.

These are policy requirements, not a declaration that every one of them is independently required by the Fourth Amendment in every police encounter.

5. Documentation should capture chronology

Because Barnes makes clear that prior events can matter, force reporting should preserve the sequence of the encounter. A strong report should document:

• what officers knew;
• when they learned it;
• what changed;
• what the subject did;
• what officers did;
• warnings given;
• tactical opportunities;
• why alternatives appeared unsafe or infeasible;
• and why the chosen force was reasonable at the time.

A report focused only on the final threat can omit legally relevant context.

6. Separate bad tactics from unconstitutional force–but do not assume they are irrelevant

Not every tactical error, policy violation, failure to use the “best” tactic, or avoidable decision is a Fourth Amendment violation. Mendez makes clear that an independent constitutional violation cannot simply be converted into excessive force through a special provocation rule, but Barnes makes equally clear that relevant preceding circumstances cannot be ignored. The current law therefore occupies an important middle ground: the Constitution does not require perfect tactics, but the force decision is evaluated in the context in which officers actually created, encountered, and understood the threat.

What the Federal Standard Does Not Establish

The federal constitutional standard does not create a universal rule that police must:

• exhaust all alternatives before using force;
• always retreat;
• always use less-lethal force before deadly force;
• always summon a tactical team;
• always wait for a negotiator;
• always use a particular distance;
• employ the least intrusive conceivable force;
• or follow the “best” police tactic identified after the fact.

Those requirements may exist under:

• state law;
• department policy;
• consent decrees;
• collective training standards;
• or specific circuit precedent.

They should not be automatically attributed to Graham. At the same time, the availability of alternatives, warnings, time, distance, containment, and officer conduct may be factually relevant to reasonableness depending on the circumstances and governing circuit law.

Research-Library Conclusion

The federal constitutional excessive-force standard is best understood as a fact-specific reasonableness framework rather than a force continuum or tactical checklist. For police seizures, Graham v. Connor requires objective reasonableness under the totality of the circumstances, while Tennessee v. Garner places important constraints on deadly force against fleeing or otherwise non-dangerous persons. Barnes v. Felix materially clarifies the modern standard by rejecting any rule that limits review to the final “moment of threat”: courts have held that they must consider all relevant circumstances, including facts and events leading up to the use of force. Barnes does not, however, establish that poor tactics or officer-created danger automatically make later force unconstitutional. Mendez rejected that kind of categorical provocation rule, and Barnes expressly left unresolved how an officer’s creation of a dangerous situation should factor into ordinary Fourth Amendment reasonableness. That question remains one of the most important areas of circuit variation. For policy purposes, the constitutional rule should be treated as a minimum legal standard; modern agency policies–including DOJ’s department-wide policy–often impose additional requirements concerning necessity, de-escalation, warnings, intervention, and medical aid that are designed to reduce avoidable force even where the Constitution may not independently require each measure in every case.

Not Legal Advice

This backgrounder is intended for research, education, policy comparison, and empirical coding. It is not legal advice and should not be used as a substitute for:

• current legal counsel;
• controlling precedent in the relevant federal circuit;
• state statutory law;
• state constitutional law;
• department policy;
• collective bargaining requirements;
• consent decrees;
• or jurisdiction-specific training standards.

Excessive-force law is highly fact dependent and continues to evolve; cases should be checked for subsequent history before being relied upon for litigation, policy, or training.
