It's an over-under and the breech is open, he's actually carrying it pretty safely. Not that I like the man at all, but he's at least not dumb enough to point a locked and loaded shotgun at himself. In this photo.
But you have seen the one where he's pointing his Viet Nam rifle at his own head, right? :^D
Breech open means the handle is bent away from the pole right? (stock and rifle are the correct terms, right?)
