What do police need in order to lawfully conduct a stop and frisk?

• A. Consent from the individual
• B. A warrant for arrest
• C. Articulable reasonable suspicion
• D. Evidence of a crime occurring

Answer: (C)

To lawfully conduct a stop and frisk, police need articulable reasonable suspicion. This legal standard requires officers to have a specific and objective basis for believing that a person is involved in criminal activity. The concept stems from the U.S. Supreme Court decision in Terry v. Ohio, which established that the Fourth Amendment allows for a limited stop—briefly detaining an individual based on a reasonable suspicion of criminal activity—followed by a quick search for weapons if the officer believes the person is armed and dangerous.

Articulable reasonable suspicion is more than just a vague hunch; it involves specific facts or circumstances that justify the stop. For example, if an officer observes someone engaging in suspicious behavior or if the person matches the description of a suspect in a crime, these could contribute to reasonable suspicion.

Consent from the individual, a warrant for arrest, or evidence of a crime occurring are not prerequisites for a stop and frisk. An officer cannot conduct a stop solely based on consent, nor do they necessarily need a warrant or proof of a crime in progress. The key element is the reasonable suspicion standard, which balances the need for effective law enforcement with the protection of individual rights against unreasonable searches and seizures.
