Besides, there are times you can be forced into a situation where you do not control sitting. Weddings, graduations, a million other things. People can be faced with situations that are difficult. That is the point of this. Or is this an easier one:
You are sitting in the back of a room, no one near you and you are next to an emergencey exit. You armed with 2 Glock 19's and a sig 228. 30 rows in front of you a guy comes out with a bow and arrow. What do you do?
If the MWG decided to do harm, wouldn't he be more likely to come in the door nearest the outer door? If he is part of the presentation, he would be more likely to come in the door you have him coming in, but what would he be doing with a rifle (or facsimile) in a school?
No matter. Can't afford to think anything but that he intends a massacre.
On a side note, a scenario is a situation one is given and needs to deal with it. Who would have thought the guy in Aurora would have came in AND out of an emergencey exit. We had very difficult scenarios in my previous life. They were made to be difficult. You did not try to rationalize the scenario by saying "why would they come in this way". You just dealt with it because that is how life is: unpredictable.
Sig, Glock or Hi Point in a life or death situation and you being the weapon you better know how to use whatever tool you have in your hand. In this case it could only be the pen in your shirt pocket. Some say if all you have is a hammer everything looks like a nail. But if all I have is a hammer and I need a board made shorter, then know how to make it work. Same is true here use what you have or don't have. But stay alive long enough to kill the SOB.
No matter what you start to do you may have to change once he reacts. How good are you at changing your plan of action in mid stream?
Since you are in control of me and have placed me directly in front of the shooter and are telling me to take control from that moment forward, then there are no options for me to choose from. We have to assume that the moment you say that I am in control of my own action that the shooter will enter and shoot the first target in front of him, which is me (remember, you already told us that he does not shoot the speaker). Since you did not give me superpowers and I am not faster than a speeding bullet, the first bullet(s) out of the gun will hit me because you placed me directly in front of the muzzle and you also made me the closest target to the muzzle.
Is there an amendment to your scenario that you would like to include which would result in options being made available to me?
I do understand that there are lessons to be learned from playing out different options in a no win situation like the Kobayashi Maru. But, unlike the Kobayashi Maru, your scenario does not allow the participant to actually participate because you have removed the options by placing the participant in front of a bullet which will be fired when the scenario starts.
Ready, Set, Go!
I would never yell "Aloha Snackbar!" because I'd be afraid that one of you gun-toting yokels would be illegally carrying and mistake me for a terrorist.
"Aloha Snackbar" has the potential to disorient the MWG, depending on his religious affiliation, but I frankly don't see why some "gun toting yokel" would shoot at someone running away from him toward the MWG under these conditions. To rescue the intruder? In any event, someone screaming that shake people out of the shock of surprise and get them moving. Your dependents will be toward the front of the escaping mob, provided they don't go into a "daddy is being dumb again" mindset ("Thank you, Hollywood"). You don't want them to be the only ones headed for the door or they become the first targets.
How about yelling "Fire, everyone out!" create a panic the bad guy hadn't planned for?
Maybe it's unfair profiling, but speaking for myself - if in the middle of a terrorist incident, I hear someone yelling "Allahu Akbar" or anything similar in the middle of the chaos, I'm more likely to assume they are part of the problem, not part of the solution.
So you believe yelling something silly may disorient the BG, but whipping a folding chair at him won't have an affect? We'll have to agree to disagree.
