DNA profiling—commonly known as DNA fingerprinting—is often heralded as unassailable criminal evidence, a veritable “truth machine” that can overturn convictions based on eyewitness testimony, confessions, and other forms of forensic evidence. But DNA evidence is far from infallible. Truth Machine traces the controversial history of DNA fingerprinting by looking at court cases in the United States and United Kingdom beginning in the mid-1980s, when the practice was invented, and continuing until the present. Ultimately, Truth Machine presents compelling evidence of the obstacles and opportunities at the intersection of science, technology, sociology, and law.
DNA fingerprinting is a revolutionary technique that enables law enforcement agencies, diagnostic laboratories and research scientists to identify minute pieces of tissue, to determine parentage and other biological family relationships. This is a study of its applications.
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.
Although DNA fingerprinting is a very young branch of molecular genetics, being barely six years old, its recent impact on science, law and politics has been dramatic. The application of DNA finger printing to forensic and legal medicine has guaranteed a high public profile for this technology, and indeed, scarcely a week goes by with out the press reporting yet another crime successfully solved by molec ular genetics. Less spectacularly, but equally importantly, DNA typing methods are steadily diffusing into an ever wider set of applications and research fields, ranging from medicine through to conservation biology. To date, two DNA fingerprinting workshops have been held in the UK, one in 1988 organised by Terry Burke at the University of Leicester, and the second in 1989 at the University of Nottingham, co-ordinated by David Parkin. In parallel with these workshops, which have provided an important focus for researchers, Bill Amos and Josephine Pemberton in Cambridge have established an informal newsletter "Fingerprint News" which is playing a major role as a forum for DNA fingerprinters. By 1989, it was clear that the field had broadened sufficiently to warrant a full international meeting. As a result, Gaudenz Dolf took on the task of organising the first, of what I hope will be many, International Symposium of DNA Fingerprinting held at Bern during Ist-3rd October 1990. The success of the meeting can be judged from the remarkable attendance, with 270 delegates from no less than 30 countries.
This exciting new book describes the use of DNA fingerprinting and its application in a wide area of plant and fungal research. It presents a thorough theoretical introduction to DNA fingerprinting, the practical aspects of extraction of DNA from the plant or fungus under study, and the statistical analysis of the data. An overview presents all species to which DNA fingerprinting is currently being applied and highlights many future technical developments.
Given the explosive development of new molecular marker techniques over the last decade, newcomers and experts alike in the field of DNA fingerprinting will find an easy-to-follow guide to the multitude of techniques available in DNA Fingerprinting in Plants: Principles, Methods, and Applications, Second Edition. Along with step-by-step annotated p
This manual presents practical approaches to using DNA fingerprinting and genetic profiling to answer a variety of biological and medical questions. It provides detailed methodology for setting up and performing experiments and evaluating results. Extensive troubleshooting tips, helpful hints, and advice for daily practice are also included. This will be a useful guide for scientists and researchers engaged in genetic identification and relationship analyses.
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.
DNA fingerprinting had a well-defined birthday. In the March 7, 1985 issue of Nature, Alec Jeffreys and coworkers described the first develop ment ofmu1tilocus probes capable of simultaneously revealing hypervari ability at many loci in the human genome and called the procedure DNA fingerprinting. It was a royal birth in the best British tradition. In a few months the emerging technique had permitted the denouement of hith erto insoluble immigration and paternity disputes and was already heralded as a major revolution in forensic sciences. In the next year (October, 1986) DNA fingerprinting made a dramatic entree in criminal investigations with the Enderby murder case, whose story eventually was turned into a best-selling book ("The Blooding" by Joseph Wambaugh). Today DNA typing systems are routinely used in public and commercial forensic laboratories in at least 25 different countries and have replaced conventional protein markers as the methods of choice for solving paternity disputes and criminal cases. Moreover, DNA fingerprinting has emerged as a new domain of intense scientific activity, with myriad applications in just about every imaginable territory of life sciences. The Second International Conference on DNA Fingerprinting, which was held in Belo Horizonte, Brazil in November of 1992, was a clear proof of this.
When DNA profiling was first introduced into the American legal system in 1987, it was heralded as a technology that would revolutionize law enforcement. As an investigative tool, it has lived up to much of this hype—it is regularly used to track down unknown criminals, put murderers and rapists behind bars, and exonerate the innocent. Yet, this promise took ten turbulent years to be fulfilled. In Genetic Witness, Jay D. Aronson uncovers the dramatic early history of DNA profiling that has been obscured by the technique’s recent success. He demonstrates that robust quality control and quality assurance measures were initially nonexistent, interpretation of test results was based more on assumption than empirical evidence, and the technique was susceptible to error at every stage. Most of these issues came to light only through defense challenges to what prosecutors claimed to be an infallible technology. Although this process was fraught with controversy, inefficiency, and personal antagonism, the quality of DNA evidence improved dramatically as a result. Aronson argues, however, that the dream of a perfect identification technology remains unrealized.
