I'd like some more details because I don't think there's anything funny about an accidental shooting. It generally means someone was careless, doesn't it?
Coming as I do from a long line of outdoorsmen, hunting accidents do happen. That being said, perhaps Mr. Cheney and his hunting buddy are getting a little too old for this and need to take up fishing rods.
Did you forget the /sarcasm tag, or just clueless?
