A priceless diamond was stolen from a glass case during a blackout. Three suspects were in the room: the guard, the thief, and the tourist. The guard swore he never left the doorway. The tourist claimed he was looking at his pocket watch in the dark. The thief claimed he was tying his shoelace. Detective Cole arrested one of them instantly without checking for fingerprints. Who did Cole arrest, and why?
The tourist
The tourist claimed he was looking at his pocket watch in the dark, which is impossible because it was a blackout and a pocket watch has no light to read the time.
