So getting back to your original point, this won't happen where weapons are allowed? Or is it more like an inverse relationship with gun freedom?
It's an inverse relationship, as
John Lott points out.
So how does this stop black market arms dealers from selling weapons in a way of which the local community would disapprove?
Care to explain to me, first, exactly what "black market" means in a society where there are no laws limiting what one can buy or sell?
