I have recently read a book by Lt. Col. Dave Grossman entitled 'On Killing: The Psychological Cost of Learning to Kill in War and Society' He has pretty in depth evidence that violence in video games and other media have made everyone less resistant to killing. I can safely say that by 16 I was able to load and unload most handguns and rifles without ever holding one. If someone handed me a gun I would know how to use it. Maybe it is because of the brainwashing but I feel safer knowing that if I had to i could use a gun.
I am not sure whether or not militaristic games have an impact on recruitment. Having played a lot of Counterstrike I always realize that if I only had one chance at the game I wouldn't last very long. In an hour session of playing people die about 20 times. Realizing this fact only makes me think that fighting with guns is a pretty bad idea.
If people really want the excitement of fighting with weapons now they can do it online or with paintballs. Why would you decide to do it with bullets?
