A flash-bang goes off BOOM! You are now blind and deaf. As you vision restores the gas hits you and your eyes tear up, then snot pours from your nose. Your lungs are burning and you cough like crazy.
From this disadvantage your plan is what exactly? Do you need a phone booth to change into Superman?
Exactly what were you a captain of? A French unit? All I hear from you is run, run, run. Nothing personal but every post you make about this is pure defeatist and surrender. I don't think anyone is talking Rambo crap here. At least I'm not. But I find it actually offensive that here, on a pro-gun, poro-2nd, pro-personal responsibility site, the only things you can say are to advocate running for your life and taking no action at all to try to deal with the guy.
Tear gas: Been there done that. Guess what, tear gas doesn't cut off your balls. And if you pop into a theater(they are moderately large rooms) and pop a tear gas canister it won't INSTANTLY fill the room. If it goes off right next to you you are certain to get a good blast of it but 10 feet away you will have to wait for it to get to you. Twenty feet away and you will maybe get a bit weepy.
Flash bang: never been hit with one have been surprised both in military training and unexpected situations. Reactions vary and always will but I have never failed to think FLOOR! whenever something happened. I probably would again. From the nice gooey floor of a theater I am sure I would have a second, maybe two to assess and think. I do know that if I survived long enough to get to the floor, my hand would be on my gun.
Would I take the guy out? Would I get myself killed? Would I wet my pant? All good questions. Whatever answers I found, I can tell you, running scared is the ONE response that I couldn't stand to live with. Better to take one of his bullets in the head.
