When I was just 16 with my learner's permit, my father took me out to teach me how to drive. It was like the second time I had ever driven on a public street. Some boys waited until I drove under an overpass & dropped an old tire on the hood of our car. My dad saw them run off - I was busy trying to keep control of the car. It scared me to death and I hate to think what my dad might have done if he could have caught those boys.
No one is saying it was right what the driver did. What I believe is the relevant point here is that parents who CARE about their children teach them not to do things like that because pranks like that can have tragic consequences.
Who is to say that the driver of the SUV (if he was indeed the real owner) hadn't had problems with those kids before? Someone with anger management problems can just go off because of something like that. Not excusing it - but parents are doing a real disservice to their children by not teaching them better. To just say "kids will be kids" isn't good enough in today's world. There are dangerous people out there & you don't bring eggs to a gunfight.
It's not an 'anger management problem'; it's a threat to your f***ing existence.
