Forensic science laboratories' reputations have increasingly come under fire. Incidents of tainted evidence, false reports, allegations of negligence, scientifically flawed testimony, or - worse yet - perjury in in-court testimony, have all served to cast a shadow over the forensic sciences. Instances of each are just a few of the quality-related charges made in the last few years. Forensic Science Under Siege is the first book to integrate and explain these problematic trends in forensic science. The issues are timely, and are approached from an investigatory, yet scholarly and research-driven, perspective. Leading experts are consulted and interviewed, including directors of highly visible forensic laboratories, as well as medical examiners and coroners who are commandeering the discussions related to these issues. Interviewees include Henry Lee, Richard Saferstein, Cyril Wecht, and many others. The ultimate consequences of all these pressures, as well as the future of forensic science, has yet to be determined. This book examines these challenges, while also exploring possible solutions (such as the formation of a forensic science consortium to address specific legislative issues). It is a must-read for all forensic scientists. Provides insight on the current state of forensic science, demands, and future direction as provided by leading experts in the field Consolidates the current state of standards and best-practices of labs across disciplines Discusses a controversial topic that must be addressed for political support and financial funding of forensic science to improve

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.

Uniting forensics, law, and social science in meaningful and relevant ways, Forensic Science and the Administration of Justice, by Kevin J. Strom and Matthew J. Hickman, is structured around current research on how forensic evidence is being used and how it is impacting the justice system. This unique book—written by nationally known scholars in the field—includes five sections that explore the demand for forensic services, the quality of forensic services, the utility of forensic services, post-conviction forensic issues, and the future role of forensic science in the administration of justice. The authors offer policy-relevant directions for both the criminal justice and forensic fields and demonstrate how the role of the crime laboratory in the American justice system is evolving in concert with technological advances as well as changing demands and competing pressures for laboratory resources.

This book provides an account of the development of forensic identification technologies and the way in which this has impacted upon the legal system. It traces the advent of forensic identification technologies, focusing on fingerprinting and forensic DNA typing, and their growing deployment within the criminal justice system. It also elucidates the ways in which these new technologies are accelerating procedural changes to investigative practices, and shows the ways in which in some areas human rights (such as privacy rights and rights against discrimination) are coming under threat. The use of forensic evidence in criminal investigations and trials is analysed in detail. This book uncovers the way in which this new reliance on forensic technologies has gained a foothold within the criminal justice system, and the risks and dangers that this can pose. The National DNA Database provides a particular focus of attention. The author seeks to move beyond an approach that has seen forensic DNA profiling as error free, situating her analysis within broader risk discourses.

Forensic DNA Applications: An Interdisciplinary Perspective was developed as an outgrowth of a conference held by the International Society of Applied Biological Sciences. The topic was human genome–based applications in forensic science, anthropology, and individualized medicine. Assembling the contributions of contributors from numerous regions around the world, this volume is designed as both a textbook for forensic molecular biology students and a reference for practitioners and those in the legal system. The book begins with the history and development of DNA typing and profiling for criminal and civil purposes. It discusses the statistical interpretation of results with case examples, mitochondrial DNA testing, Y single nucleotide polymorphisms (SNPs) and short tandem repeats (STRs), and X SNP and STR testing. It also explores low copy number DNA typing, mixtures, and quality assurance and control. The second section examines the collection and preservation of biological evidence under a variety of different circumstances and the identification of human remains—including in mass disaster settings. It discusses applications to bioterrorism investigations, animal DNA testing in criminal cases, pedigree questions and wildlife forensic problems, applications in forensic entomology, and forensic botany. The third section explores recent developments and new technologies, including the rigorous identification of tissue of origin, mtDNA profiling using immobilized probe strips, chips and next-generation sequencing, the use of SNPs to ascertain phenotypic characteristics, and the "molecular autopsy" that looks at aspects of toxicogenetics and pharmacogenetics. The book concludes with a discussion on law, ethics, and policy. It examines the use of DNA evidence in the criminal justice system in both the United States and Europe, ethical issues in forensic laboratory practices, familial searches, DNA databases, ancestry searches, physical phenotyping, and report writing. The contributors also examine DNA applications in immigration and human trafficking cases and international perspectives on DNA databases.

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 tool--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 geneticists--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.

With the popularity of crime dramas like CSI focusing on forensic science, and increasing numbers of police and prosecutors making wide-spread use of DNA, high-tech science seems to have become the handmaiden of law enforcement. But this is a myth,asserts law professor and nationally known expert on police profiling David A. Harris. In fact, most of law enforcement does not embrace science—it rejects it instead, resisting it vigorously. The question at the heart of this book is why. »» Eyewitness identifications procedures using simultaneous lineups—showing the witness six persons together,as police have traditionally done—produces a significant number of incorrect identifications. »» Interrogations that include threats of harsh penalties and untruths about the existence of evidence proving the suspect’s guilt significantly increase the prospect of an innocent person confessing falsely. »» Fingerprint matching does not use probability calculations based on collected and standardized data to generate conclusions, but rather human interpretation and judgment.Examiners generally claim a zero rate of error – an untenable claim in the face of publicly known errors by the best examiners in the U.S. Failed Evidence explores the real reasons that police and prosecutors resist scientific change, and it lays out a concrete plan to bring law enforcement into the scientific present. Written in a crisp and engaging style, free of legal and scientific jargon, Failed Evidence will explain to police and prosecutors, political leaders and policy makers, as well as other experts and anyone else who cares about how law enforcement does its job, where we should go from here. Because only if we understand why law enforcement resists science will we be able to break through this resistance and convince police and prosecutors to rely on the best that science has to offer. Justice demands no less. Visit the author's blog here.

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.
