From the PBS News Hour -- "Cornelius Dupree was sentenced to 75 years in prison after being convicted of rape and robbery at age 19 in 1980. After 30 years behind bars, new DNA testing proved his innocence and a Texas judge overturned the conviction and cleared his name." See the video.
Thirty years of a man's life wasted because somebody in law enforcement got the wrong man. A man's youth spent locked up because some some judge presided over a trial that convicted an innocent man.
