I think we can thank corporate media for ramming rap music with songs like go kill a cop, got to find me a couple of whores, and other fine anarchy driven music being fed to these zombies.
Yes. That is indeed part of it. VIOLENT Rap music, worshipping of ghetto gangsta 'culture', disrespect of the law, hopeless liberal money programs to keep people enslaved, and things like COPS on TV on Saturday have showed us for YEARS that this could and would happen. I'm not really surprised in that regard.
