Statistically, you can draw the line at any number, by listing say, murder statistics by state.
The fact is that the laws were all passed to keep minorities of one kind or another disarmed. They were never meant to be enforced against the majority.
Once they started being enforced against the majority, organized resistance against the laws built up, and has been bearing fruit for about 30 years.
I believe that we can achieve a majority of states with Constitutional carry. The more states that restore it, the easier it is to get in the remaining states.
Notice that four of the current nine were restored in the last two years!
I agree we are making progress. The doom & gloom predictions are becoming more obviously wrong and the people at large just aren’t buying that tired, worn out message any more.
