More God, Less Crime or More Guns, Less Crime?

During the last week of 2011, I spoke at and attended a wonderful salon in Santa Fe, New Mexico organized and hosted by Sandy Blakeslee, the brilliant science writer for the New York Times and the author of numerous engaging popular books on neuroscience. Two of the speakers at the salon addressed the topic of the decline of crime, one (Byron Johnson) attributing it to god and the other (John Lott) to guns.
