9.22 Particular Rights-Fourth Amendment-Unreasonable Search-Exception to Warrant Requirement-Terry Frisk is an exception to the Fourth Amendment’s requirement of a warrant for a search. This exception allows law enforcement officers to perform a limited search of a person for weapons if they have reasonable suspicion that the person is armed and dangerous. This type of search, known as a Terry Frisk, is typically conducted without a warrant in order to protect the safety of the officer and others. In the United States, this type of search is subject to the protection of the Fourth Amendment, which requires that it be reasonable under the circumstances. The Supreme Court has held that a Terry Frisk must be limited in scope and cannot be used as a general search.
