You know, in many respects...this is valuable in being as close as they likely get to reality for their purposes. Thats fair to say and it's great to see them doing this. Viability testing is a perfectly reasonable thing. Particularly when only 3 or so states have armed teachers in classrooms with children right now ...and have for a good long time now. The other 47 states (I believe it's 3.. Utah, Oregon and Texas) seem a wee bit nervous that ..I dunno? Teachers are going to shoot the kids or something? I can't say I'm really clear on what they fear a downside is when kids are being killed in a real event but this helps either way!
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.
