Since 1973, 158 people have been released from death row after evidence of their innocence was uncovered. A shocking rate of error has emerged: for every nine people executed in this country, one innocent person has been exonerated.
Wrongful convictions have been found to result from erroneous eyewitness identifications, false and coerced confessions, misconduct by police and prosecutors, inadequate legal defense, false or misleading forensic evidence, and perjury by witnesses who are promised lenient treatment or other incentives in exchange for their testimony.
Nine people have been exonerated in Alabama. Walter McMillian, Randall Padgett, Gary Drinkard, Louis Griffin, Wesley Quick, James Cochran, Charles Bufford, Anthony Ray Hinton, and Daniel Moore were found not guilty of the crimes that originally put them on Alabama's death row.
