NH legislature about to repeal concealed carry permit requirement
In AZ, concealed carry was absolutely banned (no permits available) except for peace officers, until, oh, 10-20 years ago. Then we went straight to "shall issue." A few years they repealed the ban on permitless concealed carry, so even that went (tho you can still get a permit if you want it for reciprocity purposes). If either change had any effect on human behavior, I never noticed it.
