I agree that while these violent movies may not CAUSE violent behaviour... they do desensitize it. Anyone who sees violence every day, whether it be in movies, games, or in real life, may start to think that violence is a normal and acceptable way of lfe.
I've read about the studies as well - how they are correlated but no one knows for sure what the cause is - it may be something entirely different, like the socioeconomical status of the parents ( maybe people who are poor orwealthy let their children watch more violent movies, etc).
I think something that is different today then when we were kids is the amount of violence these kids see everyday. for us, it was a few movies - for them, its everywhere.
Anyways, I think parents need to leave their kids at home. Its annoying trying to watch a movie with someones 3 year old kid with their hand in your popcorn or running around the theatre.. lol.
