Which case established that deadly force may not be used against an unarmed and fleeing suspect unless necessary?

The case that established the principle regarding the use of deadly force against an unarmed and fleeing suspect is Tennessee v. Garner. In this landmark decision, the U.S. Supreme Court ruled that law enforcement officers may not use deadly force to apprehend a suspect who poses no immediate threat to the officer or others. The court emphasized the need for a balance between the government’s interest in preventing crime and the individual’s right to life and liberty. This ruling sets a clear limitation on the circumstances under which deadly force can be justified, affirming that such extreme measures should only be employed when necessary to protect life or prevent serious injury. This case is a crucial reference point in discussions about the use of force by police and underscores the importance of evaluating the threat posed by a suspect before resorting to lethal measures.
