They (the socialist brit govt) diasrmed law abiding citizens a long time ago. Plus they’d go to jail for just having a gun, much less shooting it at a criminal. They have jailed elderly people who have defended themselves with shotguns against criminals.
A VERY proper and honorable British acquaintance of mine told me that her father (an auto mechanic in his late sixties at the time) was stopped on the sidewalk by a policeman and was quizzed about the medium-sized wrench protruding from his back pocket. The concern, of course, was that it was a potential weapon. He was required to explain the reason why he was carrying a wrench on his person, and was ultimately freed when he told the officer that he was a professional mechanic on his way to work, and was given no apologies and mild verbal harangue from the officer.
