SCENARIO. Officers receive an anonymous 911 tip that a man in a red shirt at a specific intersection has a gun in his waistband. They arrive and see a man matching the description. May they conduct a Terry frisk based on the tip alone?

  1. Yes — any tip is sufficient for a frisk
  2. No — an anonymous tip standing alone, without indicia of reliability or corroboration of facts predicting future behavior, generally does not supply reasonable suspicion (Florida v. J.L.) Correct
  3. Yes — once description is verified
  4. Yes — guns are presumed dangerous
Why: An anonymous tip about a person carrying a gun, without more, does not justify a Terry stop and frisk. Officers need additional indicia of reliability — corroboration of predictive details, observed conduct, etc.
