Louisiana death-row inmate Damon Thibodeaux exonerated with DNA evidence
First, here is some interesting, relevant data to which this case adds: (the emphasis is mine)
Of 83 exonerations in the past five years, more than 15 percent didn’t involve rape. As many as a quarter of the cases involved a false confession, in which one or more defendants admitted to the crime under interrogation.
Samuel Gross, an author of a report by the recently created National Registry of Exonerations at the University of Michigan, calculated that based on the proven rate of exonerations among death-row prisoners in the past two decades, U.S. courts appear to have an error rate in capital cases of between 2.5 percent and 4 percent.
