Related to the discussion, but there has been people disqualified from police officer jobs in USA for being too smart.
And my suggestion?
US cities are like little Africas in crime rate, and the rural areas are almost crime-free. If you live in southern USA, move north. New England is very light on crime.
Even if guns were outlawed the crime would still be disproportionally high because of the dense amount of poverty in US cities. Crime follows poverty.
