Here is a full version of the story. For those who don't read it: Basically what happens is one guy shoots a quail. Cheney and another guy head off after another covey. The first guy is coming up behind them without announcing his presence. Cheney then turns to shoot a quail and shoots him on accident. No excuses for what happened, but the full story is a little better than what you are gonna get from most news sources considering Cheney's political affiliations.
