Between a negligent discharge (nd) and an accidental discharge (ad). It seems to me that a person who experiences an ad would also be negligent.
Point being, at a pawn shop that I frequent, the owner took out his holsterd pistol (they all carry in there) to show another customer how it fit a holster he was looking at. Attempting to unload his gun, he pointed it towards the floor and away from everyone and racked the slide. it went off, causing near panic in the shop. Ha musta had his finger on the trigger. The owner is about 55 yrs old and highly experienced gun handler.
Runnin out of time, anyway scared the beejeebers out of me-5 ft away.
