On January 13, 2021, the U.S. Department of Justice (DOJ) published a statement regarding the September 2016 President’s Council of Advisors on Science and Technology (“PCAST”) report titled, Forensic Science in Criminal Courts: Ensuring Scientific Validity of Feature Comparison Methods. According to DOJ, the report "contained several fundamentally erroneous claims. Among them were that 'feature comparison' methods belong to the scientific discipline of metrology (measurement science); that feature comparison methods can only be deemed 'foundationally valid' by adhering to PCAST’s mandatory and non-severable set of experimental design criteria; and that error rates for feature comparison methods can only be established using these 'appropriately designed' black box studies.
