Final answer:
In 1985, the Supreme Court in Tennessee v. Garner set the standard for law enforcement officers' use of deadly force to prevent the escape of a potentially unarmed suspect.
Step-by-step explanation:
In 1985, the Supreme Court in Tennessee v. Garner set forth the standard to be applied in the context of a law enforcement officer's use of deadly force, and additionally determined the constitutionality of the use of deadly force to prevent the escape of an apparently unarmed suspected felon. In this case, the Court ruled that the use of deadly force to prevent the escape of a non-dangerous fleeing suspect is an unreasonable seizure under the Fourth Amendment, in the absence of probable cause to believe that the suspect poses a significant threat of death or serious physical injury to the officer or others.
The Supreme Court case in 1985 that established the standard for law enforcement's use of deadly force and the constitutionality of its use to prevent the escape of an unarmed felon is Tennessee v. Garner. In 1985, the Supreme Court in Tennessee v. Garner set forth the standard to be applied in the context of a law enforcement officer's use of deadly force, and additionally determined the constitutionality of the use of deadly force to prevent the escape of an apparently unarmed suspected felon. In this landmark decision, the Court held that the Fourth Amendment prohibits law enforcement officials from using deadly force to prevent the escape of an unarmed felony suspect, unless the officer has reasonable belief that the suspect poses a significant threat of death or serious physical injury to the officer or others.
