Bloodstain pattern experts falsely claim that they can identify the culprit of violent crimes by examining the shape and distribution of bloodstains from a crime scene. But, bloodstain pattern evidence has no grounding in any verifiable science. So how did this kind of junk science become admissible?

Josh Dubin, civil rights and criminal defense attorney, explores bloodstain pattern evidence with Pamela Colloff, senior reporter at ProPublica and staff writer at The New York Times Magazine.

Kate Judson, Executive Director of the Center for Integrity in Forensic Sciences, updates Josh Dubin's Wrongful Conviction: Junk Science.
