Media Violence vs Children

Saw something about Media Violence vs. Children today. It seems like people are so convinced that media violence is the core problem that they're ignoring anything else. Michael Moore's brilliant documentary "Bowling for Columbine" asked these questions, and found that Canadian kids watch just as much violence in Movies and on TV as US kids, and are something like 1/100th as likely to take those violent tendencies into the real world. So something is teaching US kids by example that using violence to solve problems is ok. Gee, Mr. Bush, what do you think that could possibly be?
