Yep, murder rates are declining and the number of concealed carry permits are on the rise: No doubt about that. However, the claim that murder rates are dropping because more folks are packing is a long stretch. One could claim the decrease in the murder rate is attributable to stuff like the scarcity of chili peppers: That does not make it so. After a little perusing i've discovered:
1. LA has a very high murder rate despite the fact it has concealed carry.
2. Despite that fact that southern states have good concealed carry laws; southern states, in general, have higher murder rates than anti-gun states like MA, NJ, and NY.
