In this photo made Wednesday, Feb. 22, 2012, Dallas County District Attorney Craig Watkins, center, shakes hands with attorney Cheryl Watley, right, as Richard Miles looks on in a courtroom in Dallas. Watkins, whose office has freed more than 20 wrongfully convicted inmates, questioned whether Texas has executed an innocent person and called for a statewide "conversation" about how capital punishment is administered. Watkins described himself as a moral opponent of the death penalty who has pursued it in several cases because it's the law. He also talks for the first time about his great-grandfather, who was executed in 1932 after being convicted of murder and robbery. Watkins says that dark chapter in his family's history made him more aware of what needs to be changed. (AP Photo/LM Otero) less
