There is no ignoring the impact of scientific evidence in the legal system today. New developments in science and technology are advancing at a rapid pace. These include digital and multimedia sciences, canine scent detection, touch DNA, and others. Judges, attorneys, scientists, and law enforcement personnel need to keep abreast of the scientific advances, as well as changes in the rules of evidence. There has also been much discussion about increasing juror expectations regarding such evidence (the so-called CSI effect).1

The judge who turns a blind eye to these advances and expectations does so at his or her own peril and to the detriment of the justice system. Judges must be aware of the ethical implications regarding errant experts and attorneys’ duties to verify their experts’ credentials and challenge those of the opposing party.2

Congress recognized the importance of scientific evidence to the legal system and called for the creation of an independent forensic science committee at the National Academy of Sciences (NAS) to identify the needs of the forensic science community, including assessing present and future resource needs of labs, the medical examiner, and coroner offices; identifying potential scientific advances that will assist law enforcement in using forensic technologies; and determining how to disseminate best practices and guidelines to ensure quality and consistency in the use of technologies and techniques. This effort resulted in a report, Strengthening Forensic Science in the United States: A Path Forward.3

The NAS report noted, “[L]awyers and judges often have insufficient training and background in scientific methodology, and they often fail to fully comprehend the approaches employed by different forensic science disciplines and the reliability of forensic science evidence that is offered in trial.” Additionally, the report stated, “[T]he fruits of any advances in the forensic science disciplines should be transferred directly to legal scholars and practitioners, … members of the judiciary, and [other members of the justice system] so that appropriate adjustments can be made in criminal and civil laws and procedures, model jury instructions, law enforcement practices, litigation, strategies, and judicial decision making.”

Further, “judges need to be better educated in forensic science methodologies and practices.” Two government entities were established to address the report’s recommendations: the National Commission on Forensic Science (NCFS), whose mission is to develop policy, and the Organization of Scientific Area Committees (OSAC), whose mission is to develop discipline-specific practice standards and guidelines. OSAC has a Forensic Resource Committee and NCFS has a Training on Science and Law Subcommittee, both of which are committed to greater interdisciplinary knowledge sharing between the legal and forensic science communities.

What follows is an overview of some of the valuable resources on scientific evidence that the legal profession needs and the criminal and civil justice systems require for justice to be served in today’s science- and technology-driven climate.

General Scientific Evidence Resources

  • The National Clearinghouse for Science, Technology and the Law (NCSTL) at Stetson University College of Law addresses the justice system’s escalating need for information on science, technology, and the law.

Its forensic database of bibliographic information includes books, scientific and legal journal articles, newspaper and magazine articles, seminars and conference sessions, dissertations, and organizations. The related links section provides a directory of scientific and law-related links. The education section provides handouts created for professional development presentations by NCSTL staff, transcripts, podcasts, and webcasts of lectures on forensic science and technology.
  • The National Institute of Justice’s Forensic Sciences website provided the full text of many NIJ publications related to forensic science and descriptions of NIJ programs and funding sources.

  • A Dictionary of Forensic Science is available for a fee and contains over 1,300 terms and concepts.
  • A free forensic glossary can be found at Forensics: Examining the Evidence.
  • The Crime Lab Project Forum reports on the latest news about crime labs and other forensic related stories. Readers can have frequent updates emailed to them.
  • Daubert Tracker is a subscription-based service that tracks U.S. federal and state court decisions and supporting documents about “evidentiary gatekeeping.” It provides a database of all reported decisions and many unreported decisions dating back to 1993. It also supplies information regarding the expert’s name, discipline, area of expertise challenged, and results of the challenge.
