And why have most of the police in the UK been traditionally disarmed? It's because they feared that being armed would encourage criminals to own firearms. If criminals know they may face an armed policeman they are more likely to go to the trouble of obtaining a firearm. And the UK has a much lower gun crime and homicide rate than the US. Reddbecca might want to take time out of her rantings to consider this. How well would disarming the police work in the US? Well, there are already a lot of criminals with firearms in the US so it's probably too late.
Progress is being able to admit that you are wrong.
