“Forensic science” is largely a joke to begin with. Aside from DNA identification, which was developed by actual scientists, most areas of forensic science were developed by cops, with predictable results. Ballistic matching, “hair and fibers”, blood spatter analysis, and even fingerprinting have little basis in actual science.
Yet, because of shows like CSI, juries take forensic evidence as gospel. Hopefully, stories like this will lead to a wider re-examination of our criminal justice system’s reliance on junk science.
Forensic evidence in and of itself is not “gospel”. However, it is used to build a case to beyond the point of “reasonable doubt”. One fingerprint won’t get someone convicted, but couple it with hair, footprints, tire tracks, unique clothes fibers, etc., etc., and you can be “reasonably certain” that someone has done a crime. It is most certainly NOT a “joke”.
Exept, apparently, in the case of my own state’s blood analysis lab.
