Tennessee v. Garner (1985) - Deadly Force Against a Fleeing Suspect

Quick Reference

• Citation: Tennessee v. Garner, 471 U.S. 1 (1985)

• Court: Supreme Court of the United States

• Year Decided: 1985

• Key Question: May a police officer use deadly force to prevent the escape of a fleeing suspect simply because the suspect is fleeing?

• Holding: No. Deadly force to prevent escape is a Fourth Amendment seizure, and it is constitutionally unreasonable unless the officer has probable cause to believe the suspect poses a significant threat of death or serious physical injury to the officer or others.

• Why It Matters for Officers: Garner ended the old "fleeing felon" rule. Flight alone does not justify shooting. The justification for deadly force is dangerousness, not escape.

The Facts of the Case

At about 10:45 p.m. on October 3, 1974, Memphis police officers Elton Hymon and Leslie Wright responded to a "prowler inside call." A neighbor met them and pointed to an adjacent house where she had heard glass breaking and believed someone was breaking in. (Tennessee v. Garner, 471 U.S. 1, 3-4 (1985), https://supreme.justia.com/cases/federal/us/471/1/.)

Officer Hymon went to the back of the house. He heard a door slam and saw someone run across the backyard. The fleeing suspect, Edward Garner, stopped at a six-foot-high chain link fence at the edge of the yard. With a flashlight, Hymon could see Garner's face and hands. He saw no sign of a weapon, and although he was not certain, he was "reasonably sure" and "figured" that Garner was unarmed. The Court later noted that Garner appeared to be 17 or 18 years old and about 5 feet 5 inches or 5 feet 7 inches tall. In fact, Garner was 15 years old. (471 U.S. at 3-4.)

Hymon called out "police, halt" and took a few steps toward Garner. Garner then began to climb over the fence. Convinced that Garner would escape if he made it over, Hymon shot him. The bullet struck Garner in the back of the head. Garner was taken to a hospital, where he died. Ten dollars and a purse taken from the burglarized house were found on his body. (471 U.S. at 4.)

Officer Hymon acted under the authority of a Tennessee statute and Memphis Police Department policy. The Tennessee statute provided that if, after a police officer has given notice of an intent to arrest a criminal suspect, the suspect flees or forcibly resists, "the officer may use all the necessary means to effect the arrest." The department policy was somewhat more restrictive than the statute but still permitted shooting at fleeing burglary suspects. (471 U.S. at 4-5.)

Garner's father brought suit under 42 U.S.C. Section 1983, alleging that his son's constitutional rights had been violated. The District Court found the statute and Hymon's actions constitutional. The Court of Appeals for the Sixth Circuit reversed, holding that killing a fleeing suspect is a "seizure" under the Fourth Amendment and was unreasonable on these facts. The Supreme Court granted review. (471 U.S. at 5.)

The Legal Question

The case asked whether the common-law "fleeing felon" rule could survive the Fourth Amendment. Under the old common-law rule, developed when nearly all felonies were punishable by death and when officers could not rely on firearms at a distance, a peace officer could use whatever force was necessary, including deadly force, to capture a fleeing felon. Tennessee's statute was a modern codification of that rule.

Two interpretive positions collided. Tennessee argued that apprehending criminal suspects is a core government function, that a clear escape rule promotes effective law enforcement and deters flight, and that the common-law tradition supported the statute. The competing position was that the felony category had expanded dramatically and now included many nonviolent offenses, that the common-law rule arose in a different practical world, and that taking a human life to prevent the escape of a possibly nonviolent suspect is a constitutionally unreasonable seizure.

The Court therefore had to decide both a threshold question and a merits question. The threshold question was whether shooting a fleeing suspect is a "seizure" governed by the Fourth Amendment at all. The merits question was, if it is a seizure, when such a seizure is reasonable.

The Court's Reasoning

Justice White wrote for the Court. On the threshold question, the Court held without difficulty that "there can be no question that apprehension by the use of deadly force is a seizure subject to the reasonableness requirement of the Fourth Amendment." (471 U.S. at 7.)

The Court then explained that reasonableness requires a balance. "To determine the constitutionality of a seizure, we must balance the nature and quality of the intrusion on the individual's Fourth Amendment interests against the importance of the governmental interests alleged to justify the intrusion." (471 U.S. at 8.) The Court was blunt about the weight on the individual side of the scale: "The intrusiveness of a seizure by means of deadly force is unmatched." Deadly force not only frustrates an arrest, it frustrates the suspect's interest in his own life and forecloses any judicial determination of guilt. (471 U.S. at 9.)

The Court rejected the broad fleeing-felon rule. "The use of deadly force to prevent the escape of all felony suspects, whatever the circumstances, is constitutionally unreasonable. It is not better that all felony suspects die than that they escape." (471 U.S. at 11.) Where a suspect "poses no immediate threat to the officer and no threat to others, the harm resulting from failing to apprehend him does not justify the use of deadly force to do so." (471 U.S. at 11.)

The Court also examined and discounted the common-law justification. It noted that the common-law rule developed when virtually all felonies were capital offenses and when the practical means of applying deadly force at a distance did not exist. Because the modern felony category sweeps in many nonviolent crimes, "the assumption that a 'felon' is more dangerous than a misdemeanant is untenable." (471 U.S. at 14.) The Court further observed that police departments and several states had already abandoned the broad rule, indicating that a narrower rule was workable. (471 U.S. at 18-19.)

The Holding and Its Standard

The Court held that the Tennessee statute was unconstitutional insofar as it authorized the use of deadly force against an apparently unarmed, nondangerous fleeing suspect. (471 U.S. at 11.)

The operative standard is stated in the opinion: "Where the officer has probable cause to believe that the suspect poses a threat of serious physical harm, either to the officer or to others, it is not constitutionally unreasonable to prevent escape by using deadly force." (471 U.S. at 11.)

The Court gave concrete examples of when that threshold may be met: "if the suspect threatens the officer with a weapon or there is probable cause to believe that he has committed a crime involving the infliction or threatened infliction of serious physical harm, deadly force may be used if necessary to prevent escape, and if, where feasible, some warning has been given." (471 U.S. at 11-12.)

For training audiences, the standard distills to several points:

The justification for deadly force against a fleeing suspect is dangerousness, not flight. Escape itself is not a sufficient reason.

The officer must have probable cause to believe the suspect poses a threat of serious physical harm to the officer or others. This can arise from an immediate threat (such as a weapon) or from the nature of the crime the officer has probable cause to believe was committed (a crime involving infliction or threatened infliction of serious physical harm).

A warning should be given where feasible. This is not an absolute requirement; it is qualified by feasibility.

It is worth being precise: Garner did not announce a rigid checklist that mechanically resolves every case. As the Court later clarified in Graham v. Connor, the ultimate question remains objective reasonableness under the totality of the circumstances. Garner is best read as an application of that framework to the fleeing-suspect context (see also our analysis of Graham v. Connor).

How Courts Have Applied This Since

Graham v. Connor synthesized the framework. Four years after Garner, the Court in Graham v. Connor, 490 U.S. 386 (1989), held that all excessive force claims arising from a seizure are judged under Fourth Amendment objective reasonableness. Courts now generally treat Garner as a specific application of Graham rather than a freestanding rule (see also our analysis of Graham v. Connor).

Scott v. Harris cautioned against reading Garner as a rigid test. In Scott v. Harris, 550 U.S. 372 (2007), the Court rejected the argument that Garner established a separate "preconditions" test that must be satisfied before deadly force is reasonable. The Court explained that Garner did not establish a "magical on/off switch that triggers rigid preconditions" and that the question is always whether the totality of the circumstances justified the seizure. Scott applied that reasoning to a high-speed vehicle pursuit (see also our analysis of Scott v. Harris).

Plumhoff v. Rickard and vehicle pursuits. In Plumhoff v. Rickard, 572 U.S. 765 (2014), the Court again addressed deadly force ending a dangerous high-speed chase, applying the reasonableness framework and also addressing qualified immunity (see also our analysis of Plumhoff v. Rickard).

Brower v. County of Inyo and what counts as a seizure. Garner's threshold holding, that stopping a person by deadly force is a seizure, connects to later cases refining what constitutes a Fourth Amendment seizure, including Brower v. County of Inyo, 489 U.S. 593 (1989) (see also our analysis of Brower v. County of Inyo).

Lower-court application. Federal courts of appeals have applied Garner across a wide range of facts. A recurring and difficult issue is the fleeing suspect who has committed a violent crime but presents no immediate threat at the moment of the shooting. Courts also continue to wrestle with shots fired at moving vehicles, with the suspect who momentarily turns toward an officer, and with how much earlier dangerous conduct can support a present probable-cause-of-danger finding. Outcomes are fact-intensive and there is meaningful variation among the circuits.

What This Means for Officers Today

Garner replaced a simple rule (a felon flees, an officer may shoot) with a judgment-driven standard (the officer must have probable cause that the person is dangerous). For training audiences, several points follow.

The headline is straightforward: flight by itself is not a basis for deadly force. The legally relevant question is whether the officer has probable cause to believe the fleeing person poses a threat of serious physical harm to the officer or to others.

The source of the danger assessment matters. It can come from the present moment (a visible weapon, a threatening movement) or from reliable information about the crime the person is believed to have committed. A reported armed robbery and an unverified report of a possible prowler are not the same on the dangerousness scale, and Garner asks officers to make that distinction.

The warning element is practical, not just legal. Where feasible, a clear warning gives the suspect a chance to comply and supports the reasonableness of any subsequent action.

Finally, Garner is a constitutional minimum. Most modern agency use-of-force policies, and many state statutes enacted since 2020, are more restrictive than Garner. Several states have narrowed deadly-force authority by statute, and agency policy frequently adds requirements such as exhausting reasonable alternatives. Officers are bound by the most restrictive applicable rule, which is usually agency policy or state law, not the constitutional floor.

Common Misunderstandings

"Garner means I can shoot any fleeing felon." This is the rule Garner abolished. Deadly force against a fleeing suspect requires probable cause of a threat of serious physical harm, not merely the fact of a felony or of flight. (471 U.S. at 11.)

"Garner is a rigid checklist." Scott v. Harris specifically rejected reading Garner as a set of mechanical preconditions. Garner identifies factors and examples within an overall objective-reasonableness analysis (see also our analysis of Scott v. Harris).

"If the crime was a felony, the suspect is dangerous." The Court rejected exactly this assumption, noting that the felony category includes many nonviolent offenses. Dangerousness must be assessed, not presumed from the felony label. (471 U.S. at 14.)

"A warning is always legally required." Garner requires a warning only "where feasible." It is a strongly encouraged practice, not an absolute rule. (471 U.S. at 11-12.)

"Garner only applies to firearms." Garner concerns deadly force generally. Any force that creates a substantial risk of death or serious physical injury can implicate the same analysis. The threshold question is whether the force used qualifies as deadly force under the circumstances.

CodeBlu Training Connection

Tennessee v. Garner sits directly on the boundary line that CodeBlu's training is designed to respect. CodeBlu is an AI voice-based de-escalation and crisis-intervention training product. It deliberately excludes use-of-force decision-making as a discipline. The moment an encounter becomes a deadly-force question is, by design, where a CodeBlu scenario ends. Garner is the body of law that governs what happens at and beyond that line, and it is not what CodeBlu teaches.

The honest connection is upstream. Garner concerns a narrow, high-stakes endpoint: a fleeing suspect and a split-second decision about deadly force. CodeBlu's contribution is to reduce how often officers arrive at endpoints like that. Practicing voice-based de-escalation, building rapport early, recognizing crisis behavior, and creating time and options all reduce the frequency with which an encounter accelerates toward the Garner question. CodeBlu does not claim to make officers better at the Garner analysis. It is designed to make that analysis less frequently necessary.

The case's reasoning also informs the after-action review (AAR), which scores officers 0-10 on Communication, Empathy, Safety, and Options and Problem-Solving. Garner's core idea, that the justification for an intrusive response is genuine dangerousness rather than convenience or escape, parallels the Safety dimension's focus on accurate threat assessment proportionate to the actual situation. Garner's "where feasible, some warning has been given" language connects to the Communication dimension: clear, timely warnings and commands are both a legal consideration and a de-escalation practice. The Options and Problem-Solving dimension reflects the modern trajectory of policy that grew out of Garner, which favors using time, distance, and alternatives where they are available.
