You are a rookie university police officer who has been on the job for a few weeks. While patrolling the campus one evening, you see a man emerge from a dark alley near one of the dormitories. The man appears shabby and unkempt. You tell him to stop and ask him questions. The man is nervous and somewhat incoherent but says he is a janitor in the building and has just gotten off work. You frisk him and recover bundles of crack cocaine from his pockets.

Is this evidence admissible in court under stop and frisk? Explain why.
