Willie Manning is scheduled to die by lethal injection on Tuesday for the 1992 kidnapping and murder of two white college students. No physical evidence has ever linked Manning to the crime. And the Justice Department has just come clean that the FBI's forensic analysis implicating Manning was invalid.
Latent fingerprint analysis is one of the more well-established domains of forensic science, yet these human examiners are vulnerable to the same confirmation biases that plague us all. It logically follows that other, less 'scientific' domains of forensic science that involve visual comparisons could be similarly hampered.
