Book Description
Misleading DNA Evidence: A Guide for Scientists, Judges, and Lawyers presents the reasons miscarriages of justice can occur when dealing with DNA, what the role of the forensic scientist is throughout the process, and how judges and lawyers can educate themselves about all of the possibilities to consider when dealing with cases that involve DNA evidence. DNA has become the gold standard by which a person can be placed at the scene of a crime, and the past decade has seen great advances in this powerful crime solving tool. But the statistics that analysts can attach to DNA evidence often vary, and in some cases the statistical weight assigned to that match, can vary enormously. The numbers provided to juries often overstate the evidence, and can result in a wrongful conviction. In addition to statistics, the way the evidence is collected, stored and analyzed can also result in a wrongful conviction due to contamination. This book reviews high-profile and somewhat contentious cases to illustrate these points, including the death of Meredith Kercher. It examines crucial topics such as characterization of errors and determination of error rates, reporting DNA profiles and the source and sub-source levels, and the essentials of statement writing. It is a concise, readable resource that will help not only scientists, but legal professionals with limited scientific backgrounds, to understand the intricacies of DNA use in the justice system. - Ideal reference for scientists and for those without extensive scientific backgrounds - Written by one of the pioneers in forensic DNA typing and interpretation of DNA profiling results - Ideal format for travel, court environments, or wherever easy access to reference material is vital

Book Description
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.

Book Description
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.

Book Description
a version less likely to play out on dramatic television shows. In Inside the Cell, Erin Murphy shows how DNA typing can be subject to misuse, mistake, and error, and lead to a police state run amok. Murphy shows the perils of a society in which "stop-and-frisk" becomes "stop-and-spit," or in which police pose undercover to get a DNA sample from your discarded lunch. Already, police can collect DNA when making an arrest, sometimes before charging a person with a crime. The government is building a massive DNA database, stockpiling samples from as much as a third of the male population, and the laws regulating what they can and cannot do with them are weak. Murphy shows how this invites the riskiest kind of genetic surveillance imaginable. Just because DNA testing is good science does not mean that it is foolproof. Faulty forensic science is the number two factor leading to wrongful conviction, and yet we have done little to improve the use of science in criminal justice.

Book Description
On January 20, 1984, Earl Washington—defended for all of forty minutes by a lawyer who had never tried a death penalty case—was found guilty of rape and murder in the state of Virginia and sentenced to death. After nine years on death row, DNA testing cast doubt on his conviction and saved his life. However, he spent another eight years in prison before more sophisticated DNA technology proved his innocence and convicted the guilty man. DNA exonerations have shattered confidence in the criminal justice system by exposing how often we have convicted the innocent and let the guilty walk free. In this unsettling in-depth analysis, Brandon Garrett examines what went wrong in the cases of the first 250 wrongfully convicted people to be exonerated by DNA testing. Based on trial transcripts, Garrett’s investigation into the causes of wrongful convictions reveals larger patterns of incompetence, abuse, and error. Evidence corrupted by suggestive eyewitness procedures, coercive interrogations, unsound and unreliable forensics, shoddy investigative practices, cognitive bias, and poor lawyering illustrates the weaknesses built into our current criminal justice system. Garrett proposes practical reforms that rely more on documented, recorded, and audited evidence, and less on fallible human memory. Very few crimes committed in the United States involve biological evidence that can be tested using DNA. How many unjust convictions are there that we will never discover? Convicting the Innocent makes a powerful case for systemic reforms to improve the accuracy of all criminal cases.

Book Description
This book exposes the dangerously imperfect forensic evidence that we rely on for criminal convictions. "That's not my fingerprint, your honor," said the defendant, after FBI experts reported a "100-percent identification." The FBI was wrong. It is shocking how often they are. Autopsy of a Crime Lab is the first book to catalog the sources of error and the faulty science behind a range of well-known forensic evidence, from fingerprints and firearms to forensic algorithms. In this devastating forensic takedown, noted legal expert Brandon L. Garrett poses the questions that should be asked in courtrooms every day: Where are the studies that validate the basic premises of widely accepted techniques such as fingerprinting? How can experts testify with 100-percent certainty about a fingerprint, when there is no such thing as a 100 percent match? Where is the quality control at the crime scenes and in the laboratories? Should we so readily adopt powerful new technologies like facial recognition software and rapid DNA machines? And why have judges been so reluctant to consider the weaknesses of so many long-accepted methods? Taking us into the lives of the wrongfully convicted or nearly convicted, into crime labs rocked by scandal, and onto the front lines of promising reform efforts driven by professionals and researchers alike, Autopsy of a Crime Lab illustrates the persistence and perniciousness of shaky science and its well-meaning practitioners.
