An FBI study has proven what we have known all along.

Via Breitbart:

FBI crime report figures show that Alaska, Arizona, and Wyoming–three states that abolished their concealed requirement years ago–have since witnessed a decreased in handgun murders.
This runs completely counter to the left’s doom and gloom predictions whereby they claim doing away with a government-issued carry permit will mean more bad guys carrying guns, more shootings and violence, etc.

FBI figures published by the NRA show that Alaska’s handgun murder rate “declined after the state enacted permitless carry in 2003.” Moreover, in the years since Alaska’s permit requirement was abolished “handgun murders have declined as a percentage of the total number of murders.”

A drop in handgun murders also took place in Arizona after that state abolished its concealed carry permit requirement in 2010. And in Wyoming–which abolished its permit requirement in 2011–handgun murders have declined as well.
