If everyone in the UK had handguns we'd have a lot more teenage kids mucking about with them (They'll find a way). We'd have sad emo kids venting their hatred at the world using their parents guns rather than through their fashion choices and innate ability to look moody beneath a long fringe. Computer games have got little to do with it. It's EVERYTHING to do with guns that's the problem. You have one method to prevent gun rampages. 1. Don't let anyone have a gun. Any attempt to limit exposure to gun media won't go very far, especially not in the USA where the right to have the right to shoot things is embedded in their entire social DNA. You can try and limit games and violent movies but you'll always get some families that ignore these rules no matter what. I'm not saying it should be open season on gun toting media, quite the opposite in fact. I think we need to tighten up on age restrictions, by educating people and enforcing the rules a little better. I don't think it's right that 18 / R rated movies get toys. I don't think it's right that 18 rated games get given to little kids as Christmas presents. Example. I have a 5yo twins (One of each) and they occasionally play games such as Star Wars Lego and Angry Birds. I don't let them play any FPS. They still get to shoot things, or get Lego Leia to slap Lego Han upside the head, and they still get to pop the heads of pigs, but they're not blasting away with a 3D photo-realistic semi-automatic as a rampaging enemy runs towards them.
