re: There is no excuse for a hunting accident such as this.
I am not a hunter, but from what I have seen, with bird hunting you follow your quickly moving target until you shoot. Quail tend to fly not too high above the ground, which makes this dangerous.
With deer hunting, the target is usually stationary when the hunter shoots.
I don't know how good Cheney's eye sight is. At his age I am surprised he doesn't wear glasses. Also , how quick are someone's reflexes at his age?
