According to an upcoming report by the President’s Council of Advisors on Science and Technology, much of the forensic analysis in criminal trials is not scientifically valid. The report, to be released this month, attacks the validity of analysis of evidence like bite-marks, hair, and firearms. The "lack of rigor in the assessment of the scientific validity of forensic evidence is not just a hypothetical problem but a real and significant weakness in the judicial system,” wrote the council. The Senate Judiciary Committee held hearings in 2009 and 2012 to discuss the need to strengthen forensic science, and Sen. Patrick Leahy (D-VT) introduced a forensic reform bill in 2014. EPIC has pursued FOIA requests on the reliability of proprietary forensic techniques. EPIC also filed a brief on the reliability of novel forensic techniques in the Supreme Court case Florida v. Harris.
