I know that, it's the same idea that's been bouncing around forever. The problem is the one's who think they are John Wick, shoot like Barney Fife, and lack the judgment to go unarmed if they are going to drink alcohol. That's not even touching on the joy that is racial profiling or the darker side of vigilantism. People need training to hit the target and education about when NOT to shoot, or they are just as much a problem as the thugs. There was an incident when I was in college with a foot chase in a residential area of an idiot by 4 police officers. He turned with a gun, and three of the police had a line of fire, one was slightly behind. Those three hit him twice, nonlethal, in the shoulder and leg. They also hit 2 houses, a couple of cars, and a boat. Alaskan cops get plenty of training and lots of shooting range time, but throw some exertion and adrenaline in the mix with a short barrel and look out. I don't want to be the backstop.
