You would rather than an armed criminal be safe, and that a homeowner be in danger?
Whose side are you on, Bob?
Yes, yes, we've heard that argument here too. When Florida was (one of?) the first state to pass laws where law-abiding citizens could carry concealed weapons, the hue and cry was mighty, about how "blood will run in the streets", "the Gunshine State" and all that. Not surprisingly (to me), when non-criminals were allowed to arm themselves, the criminals found other things to do. Violent crime went down in Florida, just as it has gone down in _every other state_ with CCW laws.
Oh - and I've driven in England. I found the drivers to be pretty good, especially in the "be in the proper lane on the motorway, depending on your speed". I think that maybe your assumption that your contrymen can't be trusted with deadly force, is unfair. A car, after all, is deadly force. If they're not ramming each other on the M25, they probably wouldn't be shooting each other, either.
