PCAST; (Part 2): President's Council of Advisor's on Science and Technology report: Judge Harry Edwards and Dean Jennifer Mnookin call it, "A wake-up call on the junk science infesting our courtrooms," in a Washington Post commentary..."The report is a much-needed wake-up call to all who care about the integrity of the criminal-justice system. It builds upon mounting evidence that certain types of “forensic feature-comparison methods” may not be as reliable as they have long appeared. A recent, unprecedented joint study by the Innocence Project and the FBI looked at decades of testimony by hair examiners in criminal cases — and found flaws in the testimony an astonishing 95 percent of the time. In a number of serious felonies, DNA testing has revealed that bite-mark evidence underpinning convictions was simply incorrect. More generally, faulty forensic evidence has been found in roughly half of all cases in which post-conviction DNA testing has led to exoneration. What is noteworthy about the new report is that it is written solely by eminent scientists who carefully assess forensic methods according to appropriate scientific standards. The report finds that many forensic techniques do not yet pass scientific muster. This strongly implies these techniques are not ready for use in the courtroom either."




COUNTDOWN: 15 days to Wrongful Conviction Day: (Thursday October 6, 2016);

  (Harry T. Edwards is a senior judge on the U.S. Court of Appeals for the D.C. Circuit. Jennifer L. Mnookin is dean of the UCLA School of Law. They serve as co-chairs of the Senior Advisors to the PCAST Working Group.)

GIST:  "On the popular television show “CSI,” forensic evidence was portrayed as glitzy, high-tech — and virtually infallible. Unfortunately, this depiction is often a far cry from reality. This week, a significant report issued by the President’s Council of Advisors on Science and Technology (PCAST) persuasively explains that expert evidence based on a number of forensic methods — such as bite mark analysis, firearms identification, footwear analysis and microscopic hair comparisons — lacks adequate scientific validation. Quite simply, these techniques have not yet been proved to be reliable forms of legal proof. Three flawed convictions in the nation’s capital place a human face on a disturbing truth about the modern U.S. criminal justice system, as seen in a growing body of research. Critics say that far from infallible, the forensic science system needs a complete overhaul. (Alexandra Garcia/The Washington Post) The report is a much-needed wake-up call to all who care about the integrity of the criminal-justice system. It builds upon mounting evidence that certain types of “forensic feature-comparison methods” may not be as reliable as they have long appeared. A recent, unprecedented joint study by the Innocence Project and the FBI looked at decades of testimony by hair examiners in criminal cases — and found flaws in the testimony an astonishing 95 percent of the time. In a number of serious felonies, DNA testing has revealed that bite-mark evidence underpinning convictions was simply incorrect. More generally, faulty forensic evidence has been found in roughly half of all cases in which post-conviction DNA testing has led to exoneration.  What is noteworthy about the new report is that it is written solely by eminent scientists who carefully assess forensic methods according to appropriate scientific standards. The report finds that many forensic techniques do not yet pass scientific muster. This strongly implies these techniques are not ready for use in the courtroom either.  Some of our law students have asked, “Why do we still need these other forensic methods? Can’t we just rely on DNA testing instead?” The simplest answer is that DNA is not always available in criminal prosecutions. Our students also ask, “Why don’t courts just decline to admit testimony that rests on forensic methods that have not been validated?” The truth is that we wish they did, although we also understand why that has been institutionally challenging.  Unfortunately, judges frequently rely on the experience of a forensic practitioner, and the long-standing use of a given technique, rather than focusing on the technique’s scientific validity. This is not surprising. The rule of law embraces the quest for constancy and predictability, as well as a determination to treat like cases alike. Therefore, even as many judges have come to recognize the weak scientific underpinnings of some methods, they continue to allow such testimony primarily because nearly all other judges have done so before.......... The PCAST report puts forward a plausible, workable test for validity: Forensic disciplines should pursue empirical studies designed to test error rates and accuracy in conditions akin to those found in the real world. This is a reasonable standard. For example, latent fingerprint evidence would not have met this standard just a few years ago; now, thanks to thoughtful recent research, the report finds that it does. Any forensic technique that is valid and trustworthy ought to be able to pass this test. And the converse is equally true: Any forensic technique that fails to meet this standard should not be used in court.  The integrity of our criminal-justice system deserves no less. Requiring that the forensic methods we use in court have a reasonable modicum of scientific validity is neither pro-defense nor pro-prosecution; it is, rather, both pro-science and pro-justice.
