- Any anonymous tip regardless of reliability
- A witness statement alone, regardless of credibility
Correct answer: A reasonable belief based on articulable facts that a crime has been or is being committed

A Terry stop is a brief detention based on reasonable suspicion, allowing officers to investigate without making a full arrest.
