Read here the response of the National District Attorney’s Association to the not-yet-released President’s Council of Advisors on Science and Technology (PCAST) report on forensics.
The NDAA emphasizes:
“As with all evidence presented in criminal courts, this forensic scientific evidence is subject to cross-examination as well as evaluation by the Court. Many accrediting bodies consisting of world-renowned scientists and highly skilled experts evaluate forensic labs and practitioners, helping to guarantee that only qualified forensic experts testify to solid forensic facts in our courts.”
They argue that subject matter experts or scientists might have adopted different views, but conclude:
“The determination of whether scientific evidence is reliable and therefore admissible must remain with the judiciary — while the determination of how much weight will be given to any particular piece of scientific evidence must rightfully remain with the jury.”
