Only because our criminal justice system is broken and politicians allow innocent men to die. Just ask pRick Perry and Gregg Abbott. They are so frightened by the truth they bury it, along with any review boards and hope for accountability.
open and shut cases are easy but not all of them are so clear. All men deserve the right to a fair trial and if put to death, it better be done by truth. Unfortunately the gov hates truth and is a slave to the ambitions of men.
There is no justice if a man can live out life in prison after murdering a child in cold blood.
