I just spent some time running numbers. The most successful gun control law in the U.S. was passed in Kennesaw, Ga., in 1982. The crime rate dropped 89 percent in the city, compared to the modest 10 percent drop state-wide, it has stayed at the same low level. If you are going to look at gun laws, shouldn’t you take the most successful one into account? Well, maybe not in Marietta, Ga., it is illegal to spit from a car or a bus, but perfectly legal to spit from a truck. Couldn’t find out how that’s working out.
