I asked for statistics that can be meaningfully compared. Good statistics can be highly informative, but very often I find that people pull together stats from different kinds of studies in order to make what they think is a balanced case but the two sets of stats are simply incompatible.
There is a similar thread going on at the General Board, "Women and Handguns" from which I pulled this snippet C&P'd from a thread there...www.guninfo.org, I think (granted, likely a biased source, but facts are facts)...it's is a direct answer to your query of Writer Dom re: Kennesaw:
"Fact: In 1982, Kennesaw, GA passed a law requiring heads of households to keep at least one firearm in the house. The residential burglary rate dropped 89% the following year."
