The city I live in borders Kennesaw, Ga. I had never heard of the "no murders in 25 years" factoid until today, so I looked it up on a few websites.
While I can't seem to find evidence that its 100% true, the city data and crime websites seem to concur that from 1983-1994 and the years 2001 and 2002 were free of gun homicides.
Now that I think about it, Kennesaw never really does come up in the news.
Still, I hate going to Kennesaw because the place has become one big shopping center. It has made the people lazy and uninteresting.
