The reality is the reason crime keeps going down has very little to do with guns and a whole hell of a lot to do with the aging of the population. Sorry, but 70 year olds do a whole hell of a lot fewer snatch and grabs or forcible rapes than 20 year olds. The older the population average gets the fewer violent crimes there are; that's an almost direct cause and effect where as gun ownership is all over the place with very weak correlation in a lot if not most cases.
