But... Our system right now is so paranoid against executing the falsely convicted, that stays of execution are granted when there is the faintest whiff of innocence. Prisoners are kept for decades, just to avoid wrongful execution.
Hahaha. In the United States? No. Ever heard of the Innocence Project?
In Texas? Hell no! We still have a guy on death row even though the judge who sentenced him was sleeping with the prosecutor (Charles Hood).
Until there are consequences/punishments for prosecutorial overreach, we can't even think about executing convicts.
