Two different stories about two different executions scheduled for tomorrow in two states

I was struck by these notably distinct headlines and subheadlines from USA Today about two executions scheduled for tomorrow in Alabama and Texas:

“‘I am guilty:’ Alabama inmate Derrick Dearman asks for death sentence to be carried out: Dearman says his death will bring justice to the families of the five people he killed with an ax and a gun, including a pregnant woman. He has also criticized the process that has delayed his death.”

“All evidence points to Robert Roberson’s innocence. Texas still plans to execute him.: Roberson remains scheduled to die by lethal injection despite evidence indicating he was wrongfully convicted for the death of his 2-year-old daughter Nikki, whom police believed was shaken to death.”

I have not followed either of these cases closely, though I do know know many persons beyond the USA Today writers doubt guilt in the Texas case.
