Someone who signs up for that type of work would have to do more than stand there. Not crazily rushing in like you're suggesting, but more than what was done. Glad i could educate you on common sense.
actually you did no education. you sounded like jethro on beverly hillbilliies, you just said UM THEY COULD HAVE DONE SUMTHIN!
so educate us brilliant one, what would you have done, gone rambo or bruce willis, done some tuck and rolls, dove through a window, fired at him between your legs as you rolled. i'm sure in 2 minutes you could have looked out the window and hollered , 'its all clear fellas, come on in and get this corpse' and then blown the smoke off the barrel of your gun?
