Or don't. Now that I have your attention, IMHO a move, game, or other activity (paint ball guns) only have an affect on those that have trouble decerning the difference between fantasy and reality. So you can't blame intertainment activities you can only blame the mental problem. These people that have committed atrocities with guns, I believe, would have still done something to make a statement even if no gun was available. Timothy Mc Veigh would be an example.

Any other thoughts?
