As for ur son, I guess living in the States you guys really need to watch ur every step. Really crappy!! Really ****es me off. If something like that happened with one of my boys where I live, they'd tell all the kids to straighten the hell out no matter who was at fault. Totally not hounding ur boy. But if the police did get involved, which they wouldn't, that's what would happen. Some kids r just so disgustingly behaved.
I'm so sorry you're going thru all this. *hugs*
