It is no longer contestable: innocent people sometimes get convicted of serious crimes. How often? No one knows. But this we do know: since 1989, more than 1,400 people have been released from prisons in America based on evidence of innocence. Twenty-eight of these exonerations occurred in Oklahoma, including 7 people who had been sentenced to death.
A peer-reviewed, statistically-validated study published this year in the Proceedings of the National Academy of Sciences concludes that at least 4.1 percent of defendants sentenced to death in the United States are innocent. The percentage of wrongful convictions for non-capital offenses may be even higher.
More than 26,000 people are currently incarcerated in Oklahoma. If “only” 2 percent of them are innocent of the crimes for which they were convicted, more than 500 inmates deserve to be exonerated and returned to freedom.
