Fight back against armed criminals? You make it sound like the wild west...rarely do any shoot outs occur I would imagine. If someone breaks into your house, firstly you'd be lucky to find your gun, secondly, he's no doubt far more willing to use it than you and, knowing that homeowners are regularly armed, no doubt leads to more getting shot. I don't have a gun and feel perfectly safe...whys that? Because the likelyhood of an armed housebreaker is extremely low-simply because the UK hasn't upped the anti with gun ownership because of some archaic, irrelevant law.
