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.

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.

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.

This report of the President's Commission on Law Enforcement and Administration of Justice -- established by President Lyndon Johnson on July 23, 1965 -- addresses the causes of crime and delinquency and recommends how to prevent crime and delinquency and improve law enforcement and the administration of criminal justice. In developing its findings and recommendations, the Commission held three national conferences, conducted five national surveys, held hundreds of meetings, and interviewed tens of thousands of individuals. Separate chapters of this report discuss crime in America, juvenile delinquency, the police, the courts, corrections, organized crime, narcotics and drug abuse, drunkenness offenses, gun control, science and technology, and research as an instrument for reform. Significant data were generated by the Commission's National Survey of Criminal Victims, the first of its kind conducted on such a scope. The survey found that not only do Americans experience far more crime than they report to the police, but they talk about crime and the reports of crime engender such fear among citizens that the basic quality of life of many Americans has eroded. The core conclusion of the Commission, however, is that a significant reduction in crime can be achieved if the Commission's recommendations (some 200) are implemented. The recommendations call for a cooperative attack on crime by the Federal Government, the States, the counties, the cities, civic organizations, religious institutions, business groups, and individual citizens. They propose basic changes in the operations of police, schools, prosecutors, employment agencies, defenders, social workers, prisons, housing authorities, and probation and parole officers.

Forensic Fraud is the culmination of 12 years of research by author Brent E. Turvey. A practicing forensic scientist since 1996, Turvey has rendered this first of its kind study into the widespread problem of forensic fraud in the United States. It defines the nature and scope of the problem, the cultural attitudes and beliefs of those involved, and establishes clear systemic contributors. Backed up by scrupulous research and hard data, community reforms are proposed and discussed in light of the recently published National Academy of Sciences report on forensic science. An adaptation of Dr. Turvey's doctoral dissertation, this volume relentlessly cites chapter and verse in support of its conclusions that law enforcement cultural and scientific values are incompatible, and that the problem of forensic fraud is systemic in nature. It begins with an overview of forensic fraud as a sub-type of occupational fraud, it explores the extent of fraud in both law enforcement and scientific employment settings, it establishes and then contrasts the core values of law enforcement and scientific cultures and then it provides a comprehensive review of the scientific literature regarding forensic fraud. The final chapters present data from Dr. Turvey's original research into more than 100 fraudulent examiners between 2000 and 2010, consideration of significant findings, and a review of proposed reforms to the forensic science community based on what was learned. It closes with a chapter on the numerous crime lab scandals, and closures that occurred between 2010 and 2012 – an update on the deteriorating state of the forensic science community in the United States subsequent to data collection efforts in the present research. Forensic Fraud is intended for use as a professional reference manual by those working in the criminal system who encounter the phenomenon and want to understand its context and origins. It is intended to help forensic scientist and their supervisors to recognize, manage and expel it; to provide policy makers with the necessary understaffing for acknowledging and mitigating it; and to provide agents of the courts with the knowledge, and confidence, to adjudicate it. It is also useful for those at the university level seeking a strong secondary text for courses on forensic science, law and evidence, or miscarriages of justice. - First of its kind overview of the cultural instigators of forensic fraud - First of its kind research into the nature and impact of forensic fraud, with data (2000-2010) - First of its kind typology of forensic fraud, for use in future case examination in research - Numerous profiles of forensic fraudsters - Review of major crime lab scandals between 2010 and 2012
