Video Games as a Scapegoat

In the Issues in Media book it gives an example of a kid named Warren Leblanc who murdered his friend in England and Leblanc's parents said it was because of a violent video game he had been playing. I do not believe that video games alone can be blamed for violence portrayed by kids. I believe, from what i have experienced as having played violent video games as a kid, that parents are the biggest factor in the behavior that kids inherite. If parents encourage violence or dont tell their kids that violence is bad then I believe the child will be more likely to copy the violence they see in video games.
