Robyn, if the father is behind pressing charges, then perhaps he's also responsible enough as a parent that he will tell his son "I told the mom to press charges. Don't blame your ex-girlfriend for YOUR actions and their consequences." Cuz that's the thing: not pressing charges teaches him that he can intimidate whomever he wants and get away with it. He continues to act like a tool (to use your word!). And on the flip side: what does not pressing charges teach your daughter, or the other kids being intimidated by this little dude? (I'm assuming she's not the only person toward whom his anger has been misdirected.) She should be able to stand up for herself.
As to why the principal/school didn't press charges: I'm going to assume they can't because, although it happened on their property, it didn't happen to their property. Like if I go to the mall and someone punches me, then I, not the mall owner, get the puncher arrested. (Sorry, just trying to explain what I'm thinking. I could be totally wrong. Also, I've never been punched. That was all hypothetical.
) And maybe that's another reason the principal is strongly encouraging you to press charges? Not only does he perhaps know more than he can tell you (re: this punk's actions toward other students), but he also knows that his hands are tied as to what legal actions the school can take. What I'm wondering is if the school could get him arrested for trespassing; I'm going to assume that being in the parking lot and egging her car is NOT a legal reason to be at the school, even if the perp is a student? That could be something to bring up to the principal, if you'd rather leave yourselves out of it.
