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.

Communication problems between science and the courts are widely deplored and sometimes exploited by a variety of groups. The U.S. Supreme Court has twice tightened the law of evidence to control the flow of information, but amazingly little has been written to analyze the nature of the problem and reduce the barriers. Expert Witnesses: Explaining and Understanding Science results from the first-hand experience of the contributors-who include scientists, expert witnesses, litigators, and a judge-that the cultural and interdisciplinary communications barriers between science and the law can be greatly reduced to everybody's advantage if the parties understand and respect each other's needs and positions.

This book explores challenges posed by the use of DNA evidence to the traditional features, procedures and principles of the criminal trial. It examines the limitations of existing theories of criminal trial processes in the face of increasing use of scientific evidence in the court room. The research elucidates the interconnections at trial of three epistemologies, namely legal reasoning, as represented by counsel and trial judge, common sense manifested by the jury and scientific reasoning expounded by the expert witness. Sallavaci argues that while scientific reasoning is part of this hybrid of trial languages and practices, its extended use is producing specifically novel tensions which impact on the traditional criminal trial landscape. Through the lens of DNA evidence, the book investigates how far the use of scientific evidence in the fact finding process poses challenges for the adversarial character of the proceedings and rules of evidence; how it affects the role of the judge, jury and expert witness, as well as the principle of orality and continuity of the trial. In comparing the challenges faced in English common law trials to those of the USA, this book has international scope, and will be of great use and interest to students and researchers of Criminal Law and Practice, Policing, and the role of Forensics in Law.

Matching DNA samples from crime scenes and suspects is rapidly becoming a key source of evidence for use in our justice system. DNA Technology in Forensic Science offers recommendations for resolving crucial questions that are emerging as DNA typing becomes more widespread. The volume addresses key issues: Quality and reliability in DNA typing, including the introduction of new technologies, problems of standardization, and approaches to certification. DNA typing in the courtroom, including issues of population genetics, levels of understanding among judges and juries, and admissibility. Societal issues, such as privacy of DNA data, storage of samples and data, and the rights of defendants to quality testing technology. Combining this original volume with the new update-The Evaluation of Forensic DNA Evidence-provides the complete, up-to-date picture of this highly important and visible topic. This volume offers important guidance to anyone working with this emerging law enforcement tool: policymakers, specialists in criminal law, forensic scientists, geneticists, researchers, faculty, and students.

Is scientific information misused by this country’s court system and lawmakers? Today more than ever before, lawyers, politicians, and government administrators are forced to wrestle with scientific research and to employ scientific thinking. The results are often less than enlightened. In Legal Alchemy, David Faigman explores the ways the American legal system incorporates scientific knowledge into its decision making. Praised by both legal and scientific communities when it first appeared in hardcover, Legal Alchemy shows how science has been used and misused in a variety of settings, including • The Courtroom—from the O. J. Simpson trial to the Dow Corning silicone breast implant lawsuit to landmark cases such as Roe v. Wade. • The Legislature—where Congress uses scientific information to help enact legislation about clean air, cloning, and government science projects like the space station and the superconducting super collider. • Government Agencies—who use science to determine policy on a variety of topics, from regulating sport utility vehicles to reintroducing gray wolves to Yellowstone National Park. As Faigman describes these and other important cases, he provides disturbing evidence that many judges, juries, and members of Congress simply don’t understand the science behind their decisions. Finally, he offers suggestions on how the science and legal professions can overcome their miscommunication and work together more effectively.
