The Department of Justice has just announced that it will revive a forensic science initiative that was begun in 2012, during the Obama Administration. Attorney General Jeff Sessions announced a halt to the initiative in April, in order to invite public comment.
A large number of common forensic techniques including bite marks, hair analysis, ballistics, fingerprint IDs and footprint analysis were called into question last year. The President's Council of Advisors on Science and Technology, a nonpartisan group established by Congress in 1976, issued a report that debunked the evidence produced by the techniques as unscientific.
Over the past couple of decades or so, we've seen a lot of people exonerated via DNA evidence. We've seen a litany of scandals involving overburdened, inaccurate and even criminally inadequate crime labs across the nation. We've seen forensic evidence, once considered top-shelf, decline in reputation as its collection, processing, testing and results have all been shown to be subject to error -- or worse, shown to be flawed or invalid.
