GPSTC Module 1 Practice Test

The main idea is that the Fourth Amendment allows a brief stop and a limited frisk when an officer has reasonable suspicion that a person is involved in criminal activity and may be armed. In Terry v. Ohio, a detective observed three men acting suspiciously and, out of concern for safety, halted them and performed a quick pat-down to check for weapons. The Court held this did not violate the Fourth Amendment because the officer’s safety concerns justified a brief stop and a limited search for weapons. The standard for stopping someone is reasonable suspicion—a lightweight, specific basis for suspecting criminal activity, less than probable cause but more than a mere hunch. The frisk is constrained to a pat-down to feel for weapons and cannot be a full search. This ruling shows how police power is allowed to protect officers’ safety while placing limits on intrusive intrusions. The other statements don’t fit because stops don’t require probable cause, not every search demands a warrant, and the decision reflects a balance between safety and privacy rather than an absolute extension of one side.
