This week, the President’s Council of Advisors on Science and Technology (“PCAST”) released a system-shaking report that explains how several fields of forensic analysis—including bite-mark analysis, hair comparisons, and shoeprint analysis—lack adequate scientific validation. Although many of these techniques have not been shown to be sufficiently reliable, they have been permitted to produce evidence in criminal cases across the country for many years. It is no wonder that D.C. Circuit Court of Appeals Judge Harry Edwards and Jennifer Mnookin, the dean of UCLA’s law school, wrote in the Washington Post that “[t]he report is a much-needed wake-up call to all who care about the integrity of the criminal-justice system.” Rather than waking up, however, the National District Attorneys Association (“NDAA”) is doubling down on the pseudo-science masquerading as forensic evidence. Given that district attorneys themselves widely evade accountability and face inadequate constraints on their power, perhaps it is no surprise that their representative organization is unwilling to stomach expert scrutiny of the evidence prosecutors introduce in criminal trials every day.
