A bill working its way through Congress would allow defendants better access to DNA tests and compensate those exonerated of wrongful convictions. The bill calls for almost two-billion dollars to educate DNA testers and process backlogged DNA tests. Peter Neufeld is the director of the National Innocence Project, a non-profit legal clinic that handles cases where post-conviction DNA testing could prove an inmate's innocence. He says DNA evidence has helped his organization free 138 wrongfully convicted people from prison. Of those already exonerated, at least 10 were on death row.
