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.
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.
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.
“Thought-provoking true-crime thriller…the book raises urgent questions of balancing public and private good that we’ll likely be dealing with as long as the title implies.”—Wall Street Journal A relentless detective and a civilian genealogist solve a haunting cold case—and launch a crime-fighting revolution that tests the fragile line between justice and privacy. In November 1987, a young couple from the idyllic suburbs of Vancouver Island on an overnight trip to Seattle vanished without a trace. A week later, the bodies of Tanya Van Cuylenborg and her boyfriend Jay Cook were found in rural Washington. It was a brutal crime, and it was the perfect crime: With few clues and no witnesses in the vast and foreboding Olympic Peninsula, an international manhunt turned up empty, and the sensational case that shocked the Pacific Northwest gradually slipped from the headlines. In deep-freeze, long-term storage, biological evidence from the crime sat waiting, as Detective Jim Scharf poured over old case files looking for clues his predecessors missed. Meanwhile, 1,200 miles away in California, CeCe Moore began her lifelong fascination with genetic genealogy, a powerful forensic tool that emerged not from the crime lab, but through the wildly popular home DNA ancestry tests purchased by more than 40 million Americans. When Scharf decided to send the cold case’s decades-old DNA to Parabon NanoLabs, he hoped he would finally bring closure to the Van Cuylenborg and Cook families. He didn’t know that he and Moore would make history. Genetic genealogy, long the province of family tree hobbyists and adoptees seeking their birth families, has made headlines as a cold case solution machine, capable of exposing the darkest secrets of seemingly upstanding citizens. In the hands of a tenacious detective like Scharf, genetic genealogy has solved one baffling killing after another. But as this crime-fighting technique spreads, its sheer power has sparked a national debate: Can we use DNA to catch the murderers among us, yet still protect our last shred of privacy in the digital age—the right to the very blueprint of who we are?
Raising hopes for disease treatment and prevention, but also the specter of discrimination and "designer genes," genetic testing is potentially one of the most socially explosive developments of our time. This book presents a current assessment of this rapidly evolving field, offering principles for actions and research and recommendations on key issues in genetic testing and screening. Advantages of early genetic knowledge are balanced with issues associated with such knowledge: availability of treatment, privacy and discrimination, personal decision-making, public health objectives, cost, and more. Among the important issues covered: Quality control in genetic testing. Appropriate roles for public agencies, private health practitioners, and laboratories. Value-neutral education and counseling for persons considering testing. Use of test results in insurance, employment, and other settings.
DNA testing and banking has become institutionalized in the Canadian criminal justice system. As accepted and widespread though the practice is, there has been little critique or debate of this practice in a broad public forum on the potential infringement of individual rights or civil liberties. Neil Gerlach's The Genetic Imaginary takes up this challenge, critically examining the social, legal, and criminal justice origins and effects of DNA testing and banking. Drawing on risk analysis, Gerlach explains why Canadians have accepted DNA technology with barely a ripple of public outcry. Despite promises of better crime control and protections for existing privacy rights, Gerlach's examination of police practices, courtroom decisions, and the changing role of scientific expertise in legal decision-making reveals that DNA testing and banking have indeed led to a measurable erosion of individual rights. Biogovernance and the biotechnology of surveillance almost inevitably lead to the empowerment of state agent control and away from due process and legal protection. The Genetic Imaginary demonstrates that the overall effect of these changes to the criminal justice system has been to emphasize the importance of community security at the expense of individual rights. The privatization and politicization of biogovernance will certainly have profound future implications for all Canadians.
Josiah Sutton was convicted of rape. He was five inches shorter and 65 pounds lighter than the suspect described by the victim, but at trial a lab analyst testified that his DNA was found at the crime scene. His case looked like many others -- arrest, swab, match, conviction. But there was just one problem -- Sutton was innocent. We think of DNA forensics as an infallible science that catches the bad guys and exonerates the innocent. But when the science goes rogue, it can lead to a gross miscarriage of justice. Erin Murphy exposes the dark side of forensic DNA testing: crime labs that receive little oversight and produce inconsistent results; prosecutors who push to test smaller and poorer-quality samples, inviting error and bias; law-enforcement officers who compile massive, unregulated, and racially skewed DNA databases; and industry lobbyists who push policies of "stop and spit." DNA testing is rightly seen as a transformative technological breakthrough, but we should be wary of placing such a powerful weapon in the hands of the same broken criminal justice system that has produced mass incarceration, privileged government interests over personal privacy, and all too often enforced the law in a biased or unjust manner. Inside the Cell exposes the truth about forensic DNA, and shows us what it will take to harness the power of genetic identification in service of accuracy and fairness.
The Technoscientific Witness of Rape is the first book to chart the thirty-year history of the sexual assault evidence kit and its role in a criminal justice system that re-victimizes many assault victims in their quest for medical treatment and justice.
