I spent last week in a small town in Montana with about 100 residents. Everyone had guns behind their seats, on the steering column, under their beds, everywhere! You know what . . the town has no law enforcement, no crime for over 10 years,no gang violence and everyone is civil to eachother! Who would have thunk it?
Depending on demographics, you could probably go up to around a 10k population before you’d have any sort of periodic violent crime occurring.
