Scientific Evidence Resources on the Web

By Carol Henderson and Diana Botluk

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) (https://www.nist.gov/forensics/ncfs.cfm), whose mission is to develop policy, and the Organization of Scientific Area Committees (OSAC) (https://www.nist.gov/forensics/osac/subs.cfm), 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 that 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 was created in 2003 to address the justice system’s escalating need for information on science, technology, and the law. The NCSTL website (http://ncstl.org) gathers a wide variety of forensic-related information together in one place, freely available to users. Its forensic database of bibliographic information includes books, scientific and legal journal articles, newspaper and magazine articles, seminars and conference sessions, dissertations, and organizations. Books and journals indexed in NCSTL’s database are available through interlibrary loan from the Stetson Law Library. 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 (http://www.ojp.usdoj.gov/nij/topics/forensics) provide the full text of many NIJ publications related to forensic science and descriptions of NIJ programs and funding sources. The FBI’s Handbook of Forensic Services, the text of which can be found at http://www.fbi.gov/about-us/lab/handbook-of-forensic-services-pdf, is divided into four major sections: introduction, submitting evidence, evidence examinations, and crime-scene safety.

A database of books from FORENSICnetBASE/LawENFORCEMENTnetBASE (http://www.crcnetbase.com/page/forensic_ebooks) for an annual subscription fee provides the full texts of dozens of forensic science and criminal justice books.

Several useful forensic-related websites provide either research pathfinders or a categorized directory of Web links, or both. Gelman Library’s Forensic Sciences pathfinder (http://libguides.gwu.edu/content.php?pid=9061&sid=58816) is an excellent resource. Provided by George Washington University, this site provides information about forensic-related resources in both print and online formats. Additionally, Science and Technology Resources on the Internet (http://www.istl.org/03-spring/internet.html) by Cynthia Holt, describes and links to the best forensic resources on the Internet. A Guide to Information Sources in the Forensic Sciences updates the article.

Zeno’s Forensic Site (http://forensic.to) is a Web directory of hundreds of forensic-related sites. An interesting feature of the site is its user ratings option offering useful feedback. It provides the opportunity to be informed by email when new links are added. Forensic researchers can also use Reddy’s Forensic Page (http://www.forensicpage.com), which is a topically organized directory of dozens of links related to forensic science and law.

Some unique forensic-related sites can be found online. These include Crime and Clues: The Art and Science of Criminal Investigation (http://www.crime andclues.com), a site that gathers articles about aspects of criminal investigation. It includes information about different types of scientific evidence, crime scene and death investigation, and testimony and ethics. Additionally, the National Museum of Crime and Punishment offers an online Crime Library (http://www.crimemuseum.org/crime-library) that provides background information on crime, forensic investigation, and famous cases.

Oxford Reference offers Suzanne Bell’s A Dictionary of Forensic Science (http://www.oxfordreference.com/view/10.1093/acref/9780199594009.001.0001/acref-9780199594009), which is available for a fee and contains over 1,300 terms and concepts. A smaller but free forensic glossary can be found at Forensics: Examining the Evidence (http://www.forensicbasics.org/reference-center/glossary).

Keeping up to date in any discipline can be a challenge. The Crime Lab Project Forum (http://crimelabproject.wordpress.com) is a blog that reports on the latest news about crime labs and other forensic-related stories. Readers who wish to follow the frequent updates can opt to have them delivered to their email addresses by means of a Yahoo! group. Additionally, Daubert Tracker (http://www.dauberttracker.com) 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.
