‘Junk forensic science’ topics continue to show up in the media in conjunction with the growing numbers of overturned convictions assisted by forensic experts. See: The Registry of Exonerations.
Here’s a couple of recent articles. The first talks about the FBI’s disparaged hair matching unit and another about what the top five junk forensic practices are ( includes hair characteristic comparison which is NOT mitochondrial DNA from hair).
This second article runs a short synopsis about bite marks, handwriting analysis, Shaken Baby Syndrome, penile arousal testing, and a few more.
Bite marks are still in play within the US Criminal Justice system.
