If something like this happened to my child, I would want anyone responsible held responsible. I think my main point is that holding a school or a program responsible doesn't really mean anything. You can only hold people responsible, so I don't think it makes sense to hold people responsible for something they had no responsibility in.
That said, I don't really think it is very productive to try to put myself in the position of a parent whose child was a victim. The only thing that that changes is emotional perspective, and I think the main issue with this whole argument is that people are letting emotion trump logic. As a parent of one of these kids, I would very possibly want the school burned to the ground, but that wouldn't make me right. And I certainly couldn't blame any of the actual parents for wanting that, but that doesn't mean they'd be right.
Mostly I just think that punishing any of the current players, coaches, etc. doesn't make sense from a logical standpoint, even if it might seem satisfying from an emotional one.
