Which legal principle allows officers to stop and question a person briefly?

• A. Search warrant
• B. Exclusionary rule
• C. Terry Stop or Stop and Frisk
• D. Probable cause

Answer: (C)

The correct principle that allows officers to stop and question a person briefly is the Terry Stop, also known as Stop and Frisk. This legal concept originates from the Supreme Court case Terry v. Ohio (1968), where the Court ruled that law enforcement officers are permitted to conduct a brief, investigatory stop if they have a reasonable suspicion that a person is involved in criminal activity. The key aspect of a Terry Stop is that the officer must be able to point to specific and articulable facts that justify the suspicion, meaning it cannot be based on a simple hunch or unparticular belief.

During a Terry Stop, officers are not required to have probable cause—the higher standard usually needed for making an arrest or obtaining a search warrant. Instead, the threshold of reasonable suspicion is lower than probable cause, allowing officers to ensure their safety and the safety of others while they assess the situation. If deemed necessary, an officer may also conduct a limited pat-down of a person's outer clothing to detect any weapons, but this is not a full search.

The other legal principles mentioned do not govern this situation as effectively. A search warrant requires probable cause and is a more formal process, while the exclusionary rule pertains to the inadmissibility of evidence obtained in violation
