What it can't possible show in a simulator though is what happened in Virginia Tech. Dr. Liviu Librescu is the instructor who held the classroom door closed with his own body and was shot to death in the process so his students could escape out the windows while the gunman was trying to forrce his way into the room. He'd survived the holocaust only do die that way. I have little doubt, if armed, he would have risked his life protecting more than JUST his room.
Regardless....Teachers like him are willing to die for their children/students. They can't show how effective a man with nothing to lose, everything to protect and the strength of knowing the price of failure can be if given the tool in the situation. Perhaps the gunman and not the instructor would have died, being shot to death through the door. We can't know...but we know he never got the chance.
