I just listened to the most recent Behind the Bastards on forensic 'science' used in court cases and Robert played a clip of one guy who had a Ted talk where he spoke about how he uses divining rods to find dead bodies buried in the ground.

The worst part is this guy is still employed in the field, testifies as an expert witness to get people convicted of crimes, grifts families of missing persons claiming he can find them for a fee based on their body's "unique frequency" (obtained from fingernail clippings), consults/instructs law enforcement on his techniques using taxpayer funds, and worked until recently at the famous body farm at the Univeristy of Tennessee.
