The Registry, Exonerations and False Convictions
The National Registry of Exonerations is the most comprehensive collection of exonerations in the United States ever assembled.
The great majority of false convictions never result in exoneration. Exonerations are most common among defendants wrongly convicted of the most severe violent crimes – especially murder and rape – and for those sentenced to death, life in prison, or many years in custody. Even then, whether or not a falsely convicted defendant is exonerated often depends on sheer luck.
The Registry was launched in May 2012 with a Report covering 873 exonerations from 1989 through February 2012. Since then, the Registry has added exonerations at a rate exceeding 200 a year.
About a third of the newly added exonerations are current cases which are posted within days or weeks of their occurrence. About two thirds are previously unknown exonerations that occurred months, years or decades before.
The previously unknown cases illustrate a central conclusion of our research: The exonerations we know about are just a fraction of those that have taken place.
As we continue to identify old exonerations that have remained unknown to us, we expect the range and diversity of the exonerations we list to continue to grow. For example, 83% of exonerations in our initial Report involved a rape or a murder, compared to only 62% of exonerations in the same period that were identified later by more painstaking research.
