The ruling in Terry v. Ohio impacts which legal principle?

The ruling in Terry v. Ohio significantly impacts the legal principle regarding the prohibition of unreasonable searches and seizures. In this landmark case, the Supreme Court established that police officers could perform a limited pat-down search of a person's outer clothing for weapons if they had a reasonable suspicion that the person was involved in criminal activity and potentially armed. This ruling strikes a balance between the need for law enforcement to ensure their safety and the Fourth Amendment's protection against unreasonable searches and seizures.

Terry v. Ohio introduced the concept of "stop and frisk," allowing law enforcement to detain individuals based on reasonable suspicion rather than probable cause, which is a lower standard of proof. This decision emphasizes the necessity of protecting citizens' rights while also acknowledging the practical needs of police work. Thus, the ruling directly reinforces the boundaries established by the Fourth Amendment, seeking to prevent arbitrary governmental intrusion into personal privacy while still permitting certain necessary actions by law enforcement under specific circumstances.
