Which case did the U.S. Supreme Court uphold regarding stop and frisk procedures?

The U.S. Supreme Court case that upheld stop and frisk procedures is Terry v. Ohio. In this landmark decision from 1968, the Court ruled that police officers have the authority to stop a person for questioning and pat down their outer clothing for weapons if they have a reasonable suspicion that the individual is involved in criminal activity and may be armed. This ruling is significant because it established the legal standard of reasonable suspicion, which is a lower threshold than probable cause, allowing law enforcement to engage in preemptive actions to ensure their safety and the safety of the public. The Court emphasized the balance between individual rights and the need for law enforcement to act decisively in potentially dangerous situations, thereby legitimizing the practice of stop and frisk under certain conditions.
