More guns+less violent crime? What a concept.

While reading a MSM story about decreased violent crime statistics, it occurred to me that maybe instead of LEO doing more to curb crime... that maybe, just maybe it decreased because of more guns being sold to law abiding citizens and criminals are more cautious in committing a violent crime on the chance that they may pick a armed citizen instead of a unarmed victim. I am very curious to see those statistics but will probably never because it would not be PC to advocate the "gunning down of the poor victim of circumstance who was just trying to get money to support his unfortunate drug habit" by taking the watch and wallet of a guy who is minding his own business... Oh wait... I forgot I am not PC...
