I attempted to snopes the Kenneshaw ga facts and did not find anything.'
Looking it wikipedia I found this as a portion of the listing there:
A 2001 media report stated that Kennesaw's crime rates continued to decline and were well below the national average, making citizens feel safer and more secure.[20] Later research claims that there is no evidence that [the law] reduced the rate of home burglaries [in Kennesaw],[21][22] even though the overall crime rate had decreased by more than 50% between 1982 and 2005.[23]
So apparently it is not as simple and clear as suggested by our pro-gun friends. I believe the contradictory study must have found that yes, the crime rate was down but no there was no evidence that it was because of the gun law.
As our friend likes to say (over and over and over and over) Correlation is not causation. (did I say that right?)
