Its a host of things, as mentioned above, plus the breakdown in the family unit. If these kids had involved parents who disciplined them (and had the backing of other friends, parents, & family members), the majority of these kids would never get this bad because they'd be disciplined like they should at home.
Pathetic, they should prosecute these individuals to the fullest extent of the law and stop glorifying the behavior by showing the clip all over the news.
