How about the example of Vermont when only in very recent times there was basically no gun control and very little, if any, violent crime?
Well, to talk of Vermont, you get into issues such as, there are relatively few members of minority groups in that state, and no big cities.
I’m sure it’s “politically incorrect” of me to make note of those aspects of Vermont contributing to a lower crime rate, and rate of gun violence in particular. But there are reasons why Vermont doesn’t have the same social and violence problems as places such as urban New Jersey.
One might note that Vermont’s population is 94.7% Caucasian...
But that would be racist, or something.
