Fingerprint Misidentification - Madrid Bombing

In a 330-page report , the U.S. Department of Justice explains how an Oregon attorney, Brandon Mayfield was arrested in May, 2004 in connection with the Madrid terrorist bombings on the basis of a faulty fingerprint match. The principle causes are given as: the unusual similarity of the prints, bias from the known prints of Mayfield, faulty reliance on extremely tiny details, inadequate explanations for differences in appearance, failure to assess the poor quality of similarities, and failure to examine LPF 17 (the Madrid bag) following the April 13 Negativo Report.
