i read what seems to be the main paper in support of a correlation between conceal and carry and decrease in crime. unfortunately it seemed very fishy, so i looked up the author on wikipedia. i found this in the opposition section:

Virtually all of these studies contend that there seems to be little or no effect on crime from the passage of license-to-carry laws. One by Ayres and Donohue, published in 2003, finds a temporary increase in aggravated assaults.

Rutgers sociology professor Ted Goertzel stated that "Lott's massive data set was simply unsuitable for his task", and that he "compar[ed] trends in Idaho and West Virginia and Mississippi with trends in Washington, D.C. and New York City" without proper statistical controls. He points out that econometric methods (such as the Lott & Mustard RTC study or the Levitt & Donohue abortion study) are susceptible to misuse and can even become junk science.[27]
