The results of those first 100 tests astonished me. In thirty percent of cases the DNA gathered during the investigation did not match the DNA of the suspect. In three out of ten cases not only did we have the wrong person, but the guilty person was still at large. In capital cases the stakes were unnervingly high: the prospect of executing an innocent person was only slightly more appalling than the prospect of murderers and rapists walking free, unidentified and dangerous.

The statistics today are roughly the same as they were 19 years ago. In approximately 25 percent of cases the genetic evidence recovered during an investigation does not match the DNA of the suspect. Oftentimes this discrepancy is discovered before irreparable harm is done to either the investigation or the suspect; however, too often we learn of our mistake only after time, money, and sometimes lives have been wasted on empty pursuits.

Reviews of state capital punishment systems have been ordered from the bench and governors’ mansions around the country, and with good reason...The delivery of justice also requires competent, well-trained, well-resourced lawyers for defendants in death penalty cases while simultaneously reserving capital punishment for only the most heinous of crimes.
