This is definitely sad but I can't blame the the dad or anyone for threatening him and trying to straighten him out. Sex offender list stuff was a big stretch and it sux if he was threatened with this. "Terrorist threats" is thrown around a lot now. I heard about some kids who were charged with something like this stemming from cherry bombs on a porch.
Shot we used to do as pranks can land you in prison today. Some warranted? Yes but there is a whole lot more of it that's just bullshit. Like the 7 yr old that was taken to the police station in Foley this week when the bus driver found out he had a toy gun. Was the police station really the thing to do?
He'll no. Send the kid home, spank his ass, whatever.
