I agree with GRD. Boys will be boys (even at 23 year old). Throwing stuff at cars was stupid in the first degree, and they should have been dealt with by the police....or their Fathers (who more than likely woulda delivered a big can a wup a...) on them. It's not like a bunch of gangbangers had the guy cornered. He had many other options. This is nearly as sick as the guy who got shot a couple of weeks ago (while walking his three year old to school) for yelling at a driver to slow down. I've had similar things happen to me in the past, and have chased more than one kid down to give him a brief lesson in manners (verbally). What the hell is wrong with people? You don't kill young people for doing stupid things. If you did, there would be no old people. The anti-CCW folks here in Ohio will love this one.
