A very good article. And, yes, it concerns John Lott's famous studies, as well as the assertions of a religious guy.
I can't bring myself to wade through all the comments, because I don't feel like reading the goofy opinions of the anti-gun extremists. If you can stomach it, I'm sure there are some good comments mixed in there, too. (I saw that Mr. Lott himself had posted a comment just above mine.)
