I can believe gangsta rap culture may (nevertheless I would require evidence to believe it does) affect kids characters an undesirable way but I can't believe violent computer games can make mentally healthy kids enjoying them to want doing violence in real life. I and many people I knew were such a kids enjoying violent computer games and preferring as much virtual blood and dismembering as possible but doing violence in the real world never ever came into my mind and apparently nobody of the classmates did any either. I also enjoyed crazy and violent driving in Carmageddon and GTA2 but in real life I don't even drive as I believe driving is dangerous.
