I agree fully with that. I feel that things like this is just a way for people to blame something other than themselves. That's all it is. People need to realize that things won't get better if they blame something else. If people are violent, there is a reason they are violent. Perhaps they were pressured to much and snapped, or perhaps they were abused. There are different reasons but saying you are violent because you played violent games is stupid. It's just a scapegoat to make people feel better about themselves. And if that's their logic, what about shows and movies? (I won't say music because Marilyn Manson was put down after Columbine).
Heck, I've seen more disturbing and violent images on tv than a video game.
