What must an officer demonstrate to justify a stop and frisk?

• A. Probable cause of a crime
• B. Reasonable suspicion based on specific facts
• C. A warrant for arrest
• D. Permission from a supervisor

Answer: (B)

To justify a stop and frisk, an officer must demonstrate reasonable suspicion based on specific facts. This legal standard is derived from the Fourth Amendment, which protects individuals against unreasonable searches and seizures. Reasonable suspicion is a lower standard than probable cause and allows law enforcement officers to take proactive measures when they have a particularized and objective basis for suspecting that a person is involved in criminal activity.

In practice, this means that the officer must have articulable facts that lead to the belief that a person may be armed and dangerous or engaging in criminal behavior. These facts must be more than a vague hunch or unparticular feeling; they need to be based on the officer's observations, experience, or information received that points to specific circumstances or behavior that warrant further investigation.

The other options do not align with the legal requirements for a stop and frisk. Probable cause, while necessary for making an arrest, does not apply at the stop and frisk stage. A warrant for arrest is also not necessary prior to conducting a stop and frisk. Additionally, permission from a supervisor is not required for this immediate type of contact when reasonable suspicion is present.
