Well, I'm not defending him, but hey, I think we can all recall INCREDIBLY stupid moments in our lives. I remember when I got in trouble foir stealing Pokemon Books at our Middle School bookfair (that was about 7-8 years ago). I look back now and wonder why did I try stealing something that was only what... $5? lol Even with that, though, I don't think many idioticly stupid moments on this scale of stupidity and violence (if you want to call it that...). Things like this make me wonder what our world is coming to. I mean... It generally seems like each generation of mankind is getting, more violent, more selfish, and more person than the previous. At this rate, geeze, I think mankind will either be extinct or be on the endangered species list by the year 3000 because all the selfish murderers and robbers that will be around by that time.
Anyways, as for that kid... one word... person. SO what if it was an Airsoft gun? Suspend him and put him in bootcamp. Maybe he'll learn what honest, hard work, and respect means. But yeah... it's appearent that his parents don't take care of him properly. As much as we all dislike what he did, you also can't help but feel somewhat sorry for him. Of course, it's still no excuse for doing what he did. Nothing can excuse such a thing.
