true. Most likely he's just a regular kid who lost control and did something dumb. Honestly, I hope this is a good thing for him because I've known grown men who didn't learn back when they were kids how to control their temper. Learning that lesson as an adult is a bit more painful - so I hope the kid is sufficiently bothered and just learns from this that it's not worth giving up control to your emotions.
Anyway, I agree with your sentiment - assume the best of the kid since we don't know anything other than what he did. If I were videotaped doing my dumbest things when I was 18...well, let's not go there because it would at least be very embarrassing!
