The Innocence Project

"Today, the Innocence Project launches "200 Exonerated, Too Many Wrongfully Convicted," a month-long national campaign to create state Innocence Commissions and enact other reforms that can address and prevent wrongful convictions."

On the 200th DNA Exoneration in the U.S.

"These 200 people are a remarkably diverse group - they include a rich man's son in Oklahoma, homeless people, school teachers, day laborers, athletes and military veterans. But mostly they are African-American men without money to hire good lawyers (or, sometimes, any lawyers).

Combined, these 200 people have served about 2,500 years in prison - that's roughly a million nights in prison."

....

"The 200 DNA exonerations nationwide give us irrefutable scientific proof of the flaws in the criminal justice system. We look at every exoneration to determine what caused the wrongful conviction in the first place, and we see clear patterns. More than 75% of the wrongful convictions involved eyewitness misidentification (often cross-racial misidentification, and often from more than one witness); nearly two-thirds involve forensic science errors (from simple mistakes to outright fraud); 25% were based on false confessions (as the result of coercive interrogations or defendants' limited mental capabilities)."
