Cases like Willingham? He is the only person that I know of to have been executed for a crime that did not happen. Ernest Ray Willis was a "companion" Texas case with almost the exact same evidence, and many of the same investigators but with a happier result. He was exonerated after 19 years on death row.

There are a number of wrongfully brought arson cases in Chapter 9 of my third edition and I have made them available separately in my newsletter available at [www.firescientist.com]

Cases that might interest you are TN v Terry Jackson, WI v Joseph Awe, Security First v. Herndon, IN v Fred Fegley, GA v Dahlman. There are quite a few others.
