In response to EPIC's state public records requests, Virginia and Pennsylvania have both released documents about "TrueAllele," a proprietary technique used in DNA forensic analysis. Virginia released to EPIC a validation study and validation summary prepared by the Virginia Department of Forensic Science. Pennsylvania produced purchase and service contracts, technical specifications, and user manuals for TrueAllele. Agencies in California, Louisiana, Pennsylvania, and Virginia have stated that they do not have access to the TrueAllele source code that they are using to produce evidence against defendants. EPIC's open government requests cited the importance of algorithmic transparency in the criminal justice system.
