In this country if guns were not allowed at this point, only the bad guys would have 'em. Since Hurricane Andrew in 1992, many women in Florida have hand guns. 25 women were raped in Miami. Can't google it as this was kept out of the news. Word spread through a female Broward County Judge who thought we should all know. That personally helped me after Hurricane Wilma when we had no phone service, trees in the roads, etc., as I had a rather tall, large, man outside my screened Florida room. He hesitated when he saw my gun. The 4 women staying with me, as we do when these things happen, were quite grateful.
We have much crime for several reasons. One, population. UK,a little over 65 million;USA, a little over 324 million.
Even rats in a crowded cage go crazy.
gun murder is definitely lower in UK even % wise but there is knife murder, etc---still lower.
