Yet, oddly enough, as people like John Lott have shown, there is a negative correlation between citizens carrying guns and violent crime. As the one goes up, the other goes down.
Further research has shown no correlation between gun laws, either those that restrict the carrying of weapons or those that liberalize it and the crime rate. Gun laws have a negligible effect on the crime rate. Crime rates continue to be controlled by more complex social and economic factors then gun laws. For example, Wisconsin and Tennessee have roughly the same population. Wisconsin has no concealed carry and Tennessee does. Which has the lower crime rate? Clue, it ain't Tennessee. Sort of disproves the notion doesn't it?
