See Mineral Man's post #101. Sums it up well. It was a collective effort for the incident to happen.
I gave up hunting with a guy who shot at a bird that was between he and I, and this was after I hollered at him for loading his shotgun while it was pointed at me. He didn't hit me when he shot the bird, because I was on a slight rise above the bird.
I also had someone tell me, someone I'd never hunt with, that he didn't see the problem with using the scope on his rifle to find out if the person 200 yards away was someone he knew.
Long story as to why the subject came up.
