The National Registry of Exonerations on this site. Read about it here.
The exoneration industry is entering an interesting phase. We've known for several years that the cases where DNA can lead to exoneration are drying up. See here. Now, far more than previously, the experts are focusing on the more difficult cases where DNA will not lead to exoneration. Cases involving, for example, claims of acquaintance rape. It will be interesting if any patterns or trends emerge. Our suspicion is that most wrongful convictions on the basis of acquaintance rape involve an overzealous prosecutor far more interested in notching up another "score" than justice.
