Which element is necessary for justification during a stop and frisk?

• A. A police officer's personal opinion
• B. Articulated facts indicating a crime
• C. A witness report
• D. Consent from the suspect

Answer: (B)

For a stop and frisk to be justified, there must be articulated facts indicating that a crime has been committed or is about to be committed. This standard, derived from legal precedents such as Terry v. Ohio, requires law enforcement officers to have specific, objective facts that reasonably suggest illegal activity. Mere personal opinions or hunches do not meet the legal threshold necessary for a stop and frisk; the officer must be able to articulate the facts that led to the suspicion of criminal activity.

While witness reports can provide helpful information, they are not a necessary element for justifying a stop and frisk. Similarly, consent from the suspect may influence the legality of a search but is not a requirement for establishing justification to conduct the stop initially. Hence, the correct answer emphasizes the importance of having articulated facts that provide a sound basis for suspicion, which is fundamental in upholding constitutional standards in policing.
