Well, in a Dunkin' Donuts I guess you're supposed to say you dropped it. Sounds better than saying you were cleaning it.

I'm probably going to p*** off a few people with my presumption, but I don't believe it. I think he was playing with it, and I KNOW he pulled the trigger. I'd rather be wrong on the off chance that he had an unsafe gun and it actually fell unassisted from wherever he was carrying it, than pass up the chance to be a CORRECT know-it-all and say what I said.

He was fooling with it, and he had his finger on the trigger. Perhaps he dropped it while he was fooling with it, and tried to catch it by the trigger. The gun didn't go off when it hit the floor.
