hate to tell you but i highly doubt they'll be going to jail for it, at most i'd imagine a citation and a court date.... beating the shit out of them isn't the answer tho, i'm sure the word will spread what happened there and then parents won't feel safe having their kids there, as of course no one will really know why they'll just see it as a random act of violence.... if they live by themselves... not the best suggestion, but go and follow them home, and tag their house wtih shit like "waste of life" or "don't ever do that stupid shit again".... like i said it's not the best suggestion, but better then leaving parents feeling unsafe to take their kids there and such...
