Edgar Ray Killen is set to go on trial in Philadelphia, Miss., for his alleged role in the “Philadelphia Three” murders on Monday, and the predictable flood of worldwide media coverage has materialized; probably the best pieces I’ve seen are from the New York Times and Canada’s National Post.

However, neither story makes it clear why Killen wasn’t tried again after his 1967 federal criminal trial that ended in a 11–1 hung jury; you’d think that an 11–1 jury vote would be a pretty strong indication that a second trial would have ended in a conviction… does anyone know the answer?
