Mad monkey -I understand your point, but again, if I'm in the middle of that theater, you are as big a threat, and equally unknown to me, as the crazy fucker. Take as dim a view as you like, but if I'm protecting my family in a dark theater, my Army training is going to do it's thing.
This makes me even more sure that I want nothing to do with crowds anymore. One crazy fuck and a few over zealous Rambos is too much for me. Nobody is going to stab 70+ people in a theater.
Edit - just read the linked article. I can't really think of a good enough expletive to describe it, so I'll stick with "epic BS."
