9.21 Particular Rights-Fourth Amendment-Unreasonable Seizure of Person-Exception to Warrant Requirement-Terry Stop 172 is a legal doctrine that allows police officers to detain and search a person briefly without a warrant if they have reasonable suspicion that criminal activity is afoot. This exception to the warrant requirement is named after the Supreme Court case, Terry v. Ohio, which established that officers may conduct a limited search of a person in certain circumstances. There are two types of Terry Stops: a frisk and a full search. A frisk is a pat-down search for weapons, while a full search involves more intrusive searches that involve the seizure of contraband or evidence.
