Honestly, as much as I'd love to fight for what's "right," in the case of a lawsuit I don't think they could win, I think they did what's best in the financial interests of its members. An ugly case with a personal-injury-type lawyer throwing out soundbites wouldn't do much for credibility of th sport either. As much as the scores are suspect, they can't prove he didn't shoot them when he says he did, has "witnesses," and the rules support prebowling. The carefully worded press release pretty much implied their hands were tied with the decision.
They're not shoving him for same reason that baseball doesn't exactly shove Barry Bonds down our throats. When we look to young heroes, we're looking for integrity, class, and talent. If USBC is going to start promoting young guns, I hope they start with the kids that make Jr. Team USA without the help of the legal profession.
