I remember years ago watching "All in the Family" one evening. Gloria and Meathead had just come home. They are all upset because they got mugged in the subway. Old Archie says "I could stop that right now. Give everyone a gun when they get on the subway, and they give it back when they get off. No more muggings!" Everyone laughed at the idea being preposterous. It makes a whole lot more sense than most people realize. A whole lot of good common sense there that the gun control crowd just can't seem to grasp.
