Defending Jacob

by William Landay

Here is the dirty little secret: the error rate in criminal verdicts is much higher than anyone imagines. Not just false negatives, the guilty criminals who get off scot-free—those “errors” we recognize and accept. They are the predictable result of stacking the deck in defendants’ favor as we do. The real surprise is the frequency of false positives, the innocent men found guilty. That error rate we do not acknowledge—do not even think about—because it calls so much into question. The fact is, what we call proof is as fallible as the witnesses who produce it, human beings all. Memories fail, eyewitness identifications are notoriously unreliable, even the best-intentioned cops are subject to failures of judgment and recall. The human element in any system is always prone to error. Why should the courts be any different? They are not.
