Few controversies in policing are as fraught as the use of Terry stops—temporary detentions made by officers upon reasonable suspicion of criminal activity, often accompanied by protective pat-down searches known as “frisks.” Studies have shown that racial minorities are disproportionately targeted for Terry stops, raising concerns about profiling and discrimination. Yet many police agencies view Terry stops as a critical tool in their arsenal. A related concern is the use of traffic stops—even on probable cause—to conduct more intrusive searches.
