A couple months ago, I did a back-of-the-envelope calculation which caused me to claim that Texas may have executed 54 innocent people. Soon thereafter, I vowed to review all 450 (now 451) lethal injections in Texas to see if I could identify those 54.
I used a coarse filter to rapidly exclude from consideration most of those who were executed. I do not dispute that most of the people executed were in fact guilty of a capital offense. I then designed and applied an Actual Innocence Scorecard to more carefully consider the remaining 69. I summarize below the ones I have scored so far.
