Another Candidate for Beatification

I had not heard of the artist Stetson Kennedy until this Freakonomics book came along. In a nutshell:

It was in the late 1940s that he took it upon himself to infiltrate, under the pseudonym “John Perkins,” the KKK and other terrorist groups. Evidence he gathered was instrumental in jailing a number of terrorists, and also led to such additional books as The Klan Unmasked, Southern Exposure, and Jim Crow Guide. Some of these were translated into a score of languages around the world.

He also convinced the producers of the 'Superman' radio show to air KKK secrets, make them the villain of choice for little kids, thereby utterly discrediting them.
