A scathing indictment of the growing role of junk science in our courtrooms. Peter W. Huber shows how time and again lawyers have used—and the courts have accepted—spurious claims by so-called expert witnesses to win astronomical judgments that have bankrupted companies, driven doctors out of practice, and deprived us all of superior technologies and effective, life-saving therapies.

Scores of talented and dedicated people serve the forensic science community, performing vitally important work. However, they are often constrained by lack of adequate resources, sound policies, and national support. It is clear that change and advancements, both systematic and scientific, are needed in a number of forensic science disciplines to ensure the reliability of work, establish enforceable standards, and promote best practices with consistent application. Strengthening Forensic Science in the United States: A Path Forward provides a detailed plan for addressing these needs and suggests the creation of a new government entity, the National Institute of Forensic Science, to establish and enforce standards within the forensic science community. The benefits of improving and regulating the forensic science disciplines are clear: assisting law enforcement officials, enhancing homeland security, and reducing the risk of wrongful conviction and exoneration. Strengthening Forensic Science in the United States gives a full account of what is needed to advance the forensic science disciplines, including upgrading of systems and organizational structures, better training, widespread adoption of uniform and enforceable best practices, and mandatory certification and accreditation programs. While this book provides an essential call-to-action for congress and policy makers, it also serves as a vital tool for law enforcement agencies, criminal prosecutors and attorneys, and forensic science educators.

The testimony of an expert witness can lead to success or failure in cases that hinge on the presentation’s impact on a jury. Effective Expert Witnessing, Fifth Edition: Practices for the 21st Century explores the fundamentals of litigation, trial preparation, courtroom presentation, and the business of expert witnessing. Extensively updated to reflect new developments since the last edition, it provides practical advice enabling expert witnesses and attorneys to maximize the effectiveness of their expert testimony. The Fifth Edition includes three new chapters. The first uses a hypothetical case study to explore expert witness immunity and issues related to professional malpractice and civil liability. In a chapter on psychology and the art of expert persuasion, noted social psychologist and witness preparation specialist Ann T. Greeley reveals the psychology of juries, discusses what makes an expert effective, and provides tips for conveying effective testimony through verbal and nonverbal behavior and graphics and technology. The final chapter surveys nine of the worst mistakes an expert can make and provides tips on how to avoid them. Accompanying the book are downloadable resources in which Dr. Matson introduces video clips demonstrating effective and ineffective expert testimony at deposition and trial. The book and supplemental downloadable resources provide robust strategies ensuring that expert witnesses have the best possible advantage in presenting testimony that is credible, persuasive, and compelling.

In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€"modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€"and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book.

Identifying the Culprit: Assessing Eyewitness Identification makes the case that better data collection and research on eyewitness identification, new law enforcement training protocols, standardized procedures for administering line-ups, and improvements in the handling of eyewitness identification in court can increase the chances that accurate identifications are made. This report explains the science that has emerged during the past 30 years on eyewitness identifications and identifies best practices in eyewitness procedures for the law enforcement community and in the presentation of eyewitness evidence in the courtroom. In order to continue the advancement of eyewitness identification research, the report recommends a focused research agenda.

This project addressed the admissibility of expert evidence in criminal proceedings in England and Wales. Currently, too much expert opinion evidence is admitted without adequate scrutiny because no clear test is being applied to determine whether the evidence is sufficiently reliable to be admitted. Juries may therefore be reaching conclusions on the basis of unreliable evidence, as confirmed by a number of miscarriages of justice in recent years. Following consultation on a discussion paper (LCCP 190, 2009, ISDBN 9780118404655) the Commission recommends that there should be a new reliability-based admissibility test for expert evidence in criminal proceedings. The test would not need to be applied routinely or unnecessarily, but it would be applied in appropriate cases and it would result in the exclusion of unreliable expert opinion evidence. Under the test, expert opinion evidence would not be admitted unless it was adjudged to be sufficiently reliable to go before a jury. The draft Criminal Evidence (Experts) Bill published with the report (as Appendix A) sets out the admissibility test and also provides the guidance judges would need when applying the test, setting out the key reasons why an expert's opinion evidence might be unreliable. The Bill also codifies (with slight modifications) the uncontroversial aspects of the present law, so that all the admissibility requirements for expert evidence would be set out in a single Act of Parliament and carry equal authority.
