I've previously written (here and here) about Cameron Todd Willingham and how he was convicted, sentenced to die, and executed for killing his kids, which he almost certainly did not do. The story is brilliantly told in this article by David Grann from last week's New Yorker.
As I noted, Willingham's prosecutor (the now-Judge John Jackson) published an op-ed insisting that although the arson expert who said Willingham set the fire that killed his children was wrong, since Willingham must have set the fire that killed his children, he was guilty. And we know he must have done it because he was a mean sumbitch. Or something.
Anyway, Grann has now responded to Jackson's furious, if fatuous, defense of his sending a likely innocent man to his death. If you've been following the story, it's worth a read.
