Computer Game Violence Afterthoughts

As I said video games are mostly violent but do they cause violence? It's got to be down to the individual, children that have been exposed to these graphic titles may think that taking these actions into the real world are ok, the mental state of a person could be taken into account, the persons up bringing. I think it's a combination of things that trigger violence, not just games, they are just something to blame, if they didn't exist it would be films, if they didn't exist it would be books, you could keep on going. It is unfair to just blame games.
