@Nick: are they fcuking nuts? Do they actually imagine that you might pull it out and go radio rental on somebody?
I swear this country is getting so soft, if anyone wanted to invade they could just arm a bunch of kids & grannies with none blunt ended scissors and cans of hairspray with lighters. Everyone would sh!t themselves but they wouldn't run, because that's unsafe too! If they wanted to make sure of success, they'd do it in winter, when there's an inch of snow on the ground: nobody could drive to intercept them...
