Concealed carry permits rose 215 percent between 2007 and 2015, and the murder rate dropped 14 percent during that same time period. In other words, more guns being carried for self-defense correlated with fewer murders. We've been talking about such correlation for a long time. Now Crime Prevention Research Center proved that we were right. It is absolutely clear that if criminals will understand that their victims can fight back, they would think twice before attacking. And with concealed carry, they just don't know who is carrying and who is not. So even if you don't carry, the more people do, the safer you are.
