"As with other forensic innovations, like forensic genetic genealogy or facial recognition, FDP is sold as an “investigative tool” — that is, a product not intended for use as evidence in a criminal proceeding, but as a behind-the-scenes aide to police searching for perpetrators. But selling a scientifically questionable product as a mere investigative tool can have real-world consequences.
For FDP in particular, experts warn that the composite images can reinforce racial stereotypes, encourage the over-surveillance of marginalized communities, and deny criminal defendants important information about how they became a target of an investigation, which raises serious implications for Fourth Amendment privacy rights. Composites like those Parabon sells could also inadvertently taint the memories of eyewitnesses to a crime, risking potentially valuable evidence.
Paula Armentrout, Parabon’s co-founder, provided written responses to questions from The Intercept about the company’s Snapshot program. In part, the company said that The Intercept “should not quote any of the presenters” at the NAS workshop, who it claims “made many false, uninformed, and misleading statements that were not based on evidence or facts, but on misinformation propagated by inaccurate media articles, hearsay, and their own personal and political agendas.”
Walsh insists her criticisms are motivated solely by her fidelity to the science and to ensuring the transparency and accuracy of forensic tools used in the criminal legal system. To that end, she was emphatic during the workshop: Law enforcement should not be allowed to purchase phenotyping composites. “The science isn’t there. We shouldn’t be doing it,” she said. At this juncture, she said, those sketches are about as scientific as “my son drawing them.”"
