If you check out the history of executions in Texas, though, you'll find records of executions that were later shown to be in error. I'm not going to dig out the source tonight, but one of the long-term warders at the Huntsville Penitentiary wrote a book a dozen years ago or so, and went on speaking tours. The question came up and he knows of at least one who was later shown to be innocent. Jim Willett. He runs the museum at the penitentiary now.
