Which Supreme Court decision pertains to stop and frisk procedures?

The Supreme Court decision that pertains to stop and frisk procedures is Terry v. Ohio. This landmark case established the legal precedent that law enforcement officers can stop and question an individual if they have reasonable suspicion that the person is involved in criminal activity. Additionally, if the officer believes that the individual may be armed and dangerous, they are allowed to conduct a limited pat-down search for weapons, known as a "frisk."

Terry v. Ohio clarified the balance between an officer's duty to protect public safety and the individual's right against unreasonable searches and seizures as protected by the Fourth Amendment. This case set forth the guidelines for what constitutes reasonable suspicion, allowing police officers to act decisively in potentially dangerous situations while also safeguarding citizens’ constitutional rights.
