What gets me is the parents say "All we really wanted was an apology...or for them to suspend him for two games".
But since the school's position was that there was nothing wrong with the hit and therefore neither of those things were going to happen - the parents' next step is to demand criminal charges be brought? So you're telling me it wasn't that big of a deal as long as he made little johnny feel better afterwards, but as soon as he didn't do what you demanded, it's trial time?
Damn, you let your kid play a violent sport - A sport in which its stars commonly break out into street brawls during the course of a game - and you expect your kid to never get hit? Give me a break.
