Dallas District Attorney Craig Watkins wants to review death penalty after more than 20 wrongful convictions.
The top prosecutor in Dallas County says he wants Texas to have a "conversation" about the death penalty after his office has seen more than 20 wrongfully convicted people go free.
Craig Watkins tells The Associated Press that he questions whether Texas has executed an innocent man. Twelve people once on Texas' death row have gone free.
He also says his great-grandfather's execution for murder in 1932 is a family story he learned about just in recent years. He says the incident has made him more aware of whether suspects, particularly African-Americans, are being treated fairly.
Twenty-two people in Dallas County have been exonerated through DNA evidence since 2001, most during Watkins' tenure. That's the most of any county in Texas and more than all but two states.
