Crime would go to near zero just like it did in Kennesaw, Georgia.
25 years murder-free in ‘Gun Town USA’

The crime rate initially plummeted for several years after the passage of the ordinance, with the 2005 per capita crime rate actually significantly lower than it was in 1981, the year before passage of the law.
Prior to enactment of the law, Kennesaw had a population of just 5,242 but a crime rate significantly higher (4,332 per 100,000) than the national average (3,899 per 100,000). The latest statistics available – for the year 2005 – show the rate at 2,027 per 100,000. Meanwhile, the population has skyrocketed to 28,189.
By comparison, the population of Morton Grove, the first city in Illinois to adopt a gun ban for anyone other than police officers, has actually dropped slightly and stands at 22,202, according to 2005 statistics. More significantly, perhaps, the city’s crime rate increased by 15.7 percent immediately after the gun ban, even though the overall crime rate in Cook County rose only 3 percent. Today, by comparison, the township’s crime rate stands at 2,268 per 100,000.
This was not what some predicted.
Police Lt. Craig Graydon said: “When the Kennesaw law was passed in 1982 there was a substantial drop in crime … and we have maintained a really low crime rate since then. We are sure it is one of the lowest (crime) towns in the metro area.” Kennesaw is just north of Atlanta.
