Howstuffworks writes,"As of 2001, roughly 79 percent of America's youth play video games, many of them for at least eight hours a week. Beyond the obvious issues of concern, like "what happened to riding bikes around the neighborhood," there are bigger questions. Many people wonder how this type of exposure to violence as an adolescent effects social behavior. The rise in dramatically violent shootings by teenagers, many of whom apparently play violent video games, is helping the argument that video game violence translates into real-world situations. But other people aren't convinced and insist that video games are a scapegoat for a shocking social trend that has people scared and looking to place blame. Entertainment media has always made a great scapegoat: In the 1950s, lots of people blamed comic books for kids' bad behavior.
Video games as we now know them are only about 20 years old, so there's nowhere near the amount of empirical evidence for or against their violent effects than there is surrounding, say, television violence. And even that's not a done deal."
