We'll expect a retraction and an apology

Claude Jones was executed by the great state of Texas in the year 2000 when you know who was still the governor. He had protested his innocence but was, as one would expect, put to sleep anyway. Now a crucial piece of evidence, a hair, that was supposed to have been destroyed has turned up and the Innocence Project wants a court to order that it be submitted for DNA testing. The Decider(TM) has always stated that the state of Texas never executed an innocent person. What will he do, I wonder, should the late Mr. Jones turn out to have been innocent all along?

The Reuters article states that

"no court of law has ever proven to date that an innocent person has actually been executed in the United States since the Supreme Court lifted a ban on the death penalty in 1976. But several inmates on death row have been exonerated".

I think they might find that it may be because the convicted generally stop fighting their convictions or their sentences so forcefully once they are dead.
