Evidence on Trial
March 11, 2016
(Science) – Hair analysis is only one of many flawed forensic fields: A 2009 report from the National Research Council found that the analysis of many types of evidence—from footprints and tire tracks to bullet marks and blood splatters—lacks a solid foundation. Even DNA evidence, seen as the gold standard, can land innocent people in jail, now that new technologies can detect minuscule amounts of genetic material. Forensic analysts are trying to do better. Many fields are testing the accuracy of existing methods and developing new ones that are more science-based.
