That's simply not true given just the other day a terrorist with a knife was stopped after injuring 1 person. People didn't just stand there, in fact 7 people at a distance filmed the event! But it's beside the point as I'm on about guns. A knife is a relatively low threat as it only takes a couple of blokes to restrain someone like that as proven. When they have a gun, you run, you cover loved ones and take the chasing bullets if you have to, but you don't stand up to that. Likewise with a suicide vest, they don't announce they have one and give you a chance to fight, they walk into a crowd and detonate. You won't see them coming. All well and good acting the big man, but when you're dead it won't matter. For the record if it was a knife wielding maniac, I'd want a few other blokes to circle him and close in. I'm happy to take that risk as if he gets close enough to any of us, someone else can grab him. But with guns/bombs... Nah. Screw the big man act, I'd rather be alive than righteous.
