Which supreme court case gives officers the right to frisk a person they have legally detained if the officer believes the person has a weapon?

The Supreme Court case that gives officers the right to frisk a person they have legally detained is Terry v. Ohio (1968). In this landmark decision, the Court ruled that police officers can perform a limited pat-down search, known as a "stop and frisk," if they have reasonable suspicion that the person is armed and dangerous. This ruling established the legal standard for stop-and-frisk encounters, balancing the need for officer safety with individual rights.
