Just for info's sake, the criminologists have had a lot to say about Lott's original claims. Even progun criminologists think it is a controversial claim.

One can use Google scholar to see the current debate. Being very pro-gun, I mention this as if you just use Lott as evidence, you can get in scholarly trouble. You need to know the newer stuff.

That area is mess - you need to understand complex regression statistics to have a handle on it.

A heads up. Kleck is seen as a better source.
