a match, varies from examiner to examiner and from laboratory to laboratory. The decision process, unfortunately, is entirely subjective to the individual running the tests and there is no way to ensure that the examiner will not be susceptible to observer bias. In 2004, after the Madrid train bombings, there were partial fingerprints identified from the bags of the explosives that had been left at the station. After careful consideration, it was determined by the FBI that the fingerprints left on the bag had matched to an individual in Portland, Oregon named Brandon Mayfield. This case, however, went on to change the entire outlook of fingerprint identification within the FBI, as it was later determined that he had been wrongly arrested. Because of this, the FBI is no longer able to testify that fingerprint identification is a 100% accurate technique for profiling, and should therefore be considered very carefully by anyone who uses it.
