How is fingerprint evidence used differently since the Mayfield case?

A federal judge yesterday cleared Portland attorney Brandon Mayfield of ties to the Madrid train bombings after the FBI made the stunning admission that it erred when analyzing a copy of fingerprints.

Portland's FBI Special Agent in Charge, Robert Jordan, said the error, based on a "substandard" copy of the prints, will prompt the agency to review its guidelines for making identifications and ask an international panel of experts to analyze what went wrong.
