1. I think it's unlikely-but-possible that Cheney and Co. thought they could cover up the shooting, and that would help explain their behavior. Next question if this is true: why did they think a coverup might work? Based on past experience? Seems like a legitimate question for Cheney is whether he's ever shot anyone before.
2. I'm not the only one who's noticed that Cheney's shooting victim was more apologetic than Cheney. What my lawyer side noticed is that Cheney acknowledged responsibility for shooting Whittington and said it ruined his day, but Cheney never acknowledged that he screwed up.
3. The only thing left that I can tell is to ask Cheney whether he accepts the victim's apology and forgives him. I guess it depends on whether Cheney believes that Whittington was sufficiently contrite and sincere in his apology.
