How do you think he got that mentality? Let me guess, video games? Or was it the music? Nah, it's Obama's fault. Shit, it's no ones fault but the parents.
Seriously? You really believe that a parent has no infuence on a what a child does? Obvious that niether of you have children And you both contradict yourselves. You say that the parent isnt at fault but the gun should have been locked up
The parents obviously screwed up for letting their kid have the mindset that could cause him to kill. And why wasn't the gun out of reach? Or locked up? Parenting FAIL!!!
