I would not be surprised if the number of violent acts committed by youths is a direct function of the number of hours that are available to youths to commit violent acts. Ignoring all issues of psychology and culture, perhaps it's just harder to find time to go out and commit violent acts if you're spending all your time committing violent acts alone or with buddies on your computer. A Saturday night playing GTA vs a Saturday night out and about. Which one is going to result in a 911 call?It's true that kids today play incredibly violent games like Halo and Grand Theft Auto, but as the games' popularity increased over the past 20 years, youth violence dropped 55 percent. In Japan, kids spend more time playing violent games, and there's even less violence. And in America, despite media hype, there are fewer school shootings now, not more.
