Via The Intercept:
“As an analytical scientist, whenever someone gives me absolute certainty, my red flag goes up,” said Jason Latham, who worked as a biochemist prior to becoming a forensic scientist and certified video examiner. “When I came from analytical sciences to forensic sciences, I was like some of these guys are not scientists. They are voodoo witchcraft.”
Forensic reports generally provide few details about the methods they use to arrive at points of similarity. But in Talley’s case, the FBI examiner’s report displayed a high degree of certainty. George Reis, a facial examiner who has testified more than 50 times for state, federal, and military courts throughout the country on forensic visual comparisons, pointed out that the report on Talley’s case was vague. “It is generally considered best practice to be specific in reports and to point out features of similarity, as well as differences, in any comparison illustration or chart,” Reis noted. “In the Talley case no such markings exist. The video frames that were used in the FBI illustration were of poor quality and limited value.”
Facial recognition: sorta fun if you’re using it for commercial stuff like tagging your friends, but really dangerous if its part of what is used to convict persons for crimes they’re alleged to have committed.
