That’s the Opportunity Institute’s estimate of the cost of wrongful convictions and other failed prosecutions in California’s criminal justice system. The report 692 adult felony criminal cases from 2000–2012 where the defendant was convicted of felony or felonies, the convictions were reversed, and the charges were either dismissed or the defendant subsequently found not guilty on retrial. It examines the types of cases susceptible to error, the types of error that exist, and the direct costs of incarceration, representation, and compensation attributable to these cases and their ultimate resolution.
