Forensic Science in Court explores the legal implications of forensic science—an increasingly important and complex part of the justice system. Judge Donald Shelton provides an accessible overview of the legal aissues, from the history of evidence in court, to "gatekeeper" judges determining what evidence can be allowed, to the "CSI effect" in juries. The book describes and evaluates various kinds of evidence, including DNA, fingerprints, handwriting, hair, bite marks, tool marks, firearms and bullets, fire and arson investigation, and bloodstain evidence. Assessing the strengths and limitations of each kind of evidence, the author also discusses how they can contribute to identifying the "who," "how," and "whether" questions that arise in criminal prosecutions. Author Donald Shelton draws on the depth of his experiences as courtroom prosecutor, professor, and judge, to provide a well-rounded look at these increasingly critical issues. Case studies throughout help bring the issues to life and show how forensic science has been used, both successfully and not, in real-world situations.

This book explains the correct logical approach to analysis of forensic scientific evidence. The focus is on general methods of analysis applicable to all forms of evidence. It starts by explaining the general principles and then applies them to issues in DNA and other important forms of scientific evidence as examples. Like the first edition, the book analyses real legal cases and judgments rather than hypothetical examples and shows how the problems perceived in those cases would have been solved by a correct logical approach. The book is written to be understood both by forensic scientists preparing their evidence and by lawyers and judges who have to deal with it. The analysis is tied back both to basic scientific principles and to the principles of the law of evidence. This book will also be essential reading for law students taking evidence or forensic science papers and science students studying the application of their scientific specialisation to forensic questions.
The interpretation and evaluation of scientific evidence and its presentation in a court of law is central both to the role of the forensic scientist as an expert witness and to the interests of justice. This book aims to provide a thorough and detailed discussion of the principles and practice of evidence interpretation and evaluation by using real cases by way of illustration. The presentation is appropriate for students of forensic science or related disciplines at advanced undergraduate and master's level or for practitioners engaged in continuing professional development activity. The book is structured in three sections. The first sets the scene by describing and debating the issues around the admissibility and reliability of scientific evidence presented to the court. In the second section, the principles underpinning interpretation and evaluation are explained, including discussion of those formal statistical methods founded on Bayesian inference. The following chapters present perspectives on the evaluation and presentation of evidence in the context of a single type or class of scientific evidence, from DNA to the analysis of documents. For each, the science underpinning the analysis and interpretation of the forensic materials is explained, followed by the presentation of cases which illustrate the variety of approaches that have been taken in providing expert scientific opinion.
Forensic science has been variously described as fascinating, challenging and even frightening. If you have only a vague concept of what forensic science is, this book will provide the answer. Aimed at non-scientists, or those with limited scientific knowledge, Crime Scene to Court covers all three main areas of an investigation where forensic science is practised, namely the scene of the crime, the forensic laboratory and the court. Coverage includes details of how crime scene and forensic examinations are conducted in the United Kingdom, the principles of crime scene investigations and the importance of this work in an investigation, and courtroom procedures and the role of the expert witness. The latest methods and techniques used in crime scene investigation and forensic laboratories are reported, cases are presented to illustrate why and how examinations are performed to generate forensic evidence and there is a bibliography for each chapter which provides further material for those readers wishing to delve deeper into the subject. This revised and updated edition also includes coverage on changes in professional requirements, the latest developments in DNA testing and two new chapters on computer based crimes and Bloodstain Pattern Analysis. Ideal for those studying forensic science or law, the book is intended primarily for teaching and training purposes. However, anyone with a role in an investigation, for example police, crime scene investigators or indeed those called for jury service, will find this text an excellent source of information.
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.

The second edition of Forensic Evidence in Court updates the original version, which was published in 2007. This edition continues to focus on the use of forensic evidence in criminal trials by examining particular case studies. In addition, it adds two new topics: 1. Computer and Digital Forensics 2. Firearms, Ballistics, and Toolmarks This edition includes several significant developments in the use of forensic evidence at trial since 2007. The first is the U.S. Supreme Court case, Melendez-Diaz v. Massachusetts, which established a right under the Confrontation Clause of the U.S. Constitution to cross-examine certain forensic analysts. That case involved an analyst who certified that a substance linked to the defendant was cocaine. This right was subsequently extended to an analyst who performed a blood alcohol test. However, when the Supreme Court was asked to rule on the applicability of this rule to DNA examiners, it stated that the examiner would be required to testify only if the results of the test were "testimonial" in nature. The case has been criticized and some lower courts have subsequently refused to follow it. Another significant development was the release of a report on the scientific reliability of forensic testing in many different areas issued by the National Research Council. The Report, called Strengthening Forensic Evidence: A Path Forward, called for more scientific testing and for standardization in qualification of examiners and in laboratory conditions. The only area of forensic examination that the report viewed as scientifically reliable is DNA. Various government agencies have been established to attempt to implement some of these recommendations. Funding is obviously a huge obstacle to implementing many of the recommendations. A development in forensics itself involved the extension of newer technologies in DNA testing, including a process called "Low Copy DNA," which tests quantities previously too small to type as well as DNA test kits that can be used at crime sites. A further development is the expansion of computer hacking, computer fraud and the ubiquitous nature of computers in society. We have added a new chapter to reflect what will continue to be a contentious issue in court-- "proving location and events with digital evidence." Advances in the psychological sciences have results in courts addressing issues of eyewitness testimony. Courts are coming to realize that eyewitness identifications are not as reliable as once thought. As such, courts are struggling with how best to address these issues: through jury instructions, expert testimony, or though some other method. It has come to light that eyewitness identification issues once thought to be within the "ken" of the average juror are most certainly not, and are appropriate for some manner of court intervention. This book can be used in courses for the following degrees: paralegal, criminal justice, sociology, and political science. Forensic Evidence in Court is also appropriate for use in a legal specialty course. Assignments include case law research, study of rules of evidence, how to select and prepare an expert witness, comparison of legal tests used to admit forensic evidence, study of standards used to review admission of forensic experts on appeal, and written work demonstrating critical analysis. Any attorney can teach this course, using the Teacher's Manual and sample assignments. Adjuncts experienced in criminal law or extensive use of expert testimony are particularly well suited. Guest lecturers from state forensic laboratories and state law enforcement forensic investigators give added perspective.
Shelton describes the startling questions that have arisen about the reliability of many forms of scientific evidence which were traditionally regarded as reliable and have been routinely admitted to prove guilt. The exonerations resulting from the development of DNA have exposed the lack of truswortiness of much of the "scientific" evidence that was used to convict people who turned out to be innocent. The Congressionally commissioned report of the National Academy of Sciences documented the lack of scientific basis in many of these areas. Nevertheless, Shelton discloses that many courts continue to routinely admit such evidence in criminal cases, in spite of the obligation of judges to be the "gatekeepers" of forensic science evidence. He explores reasons for that phenomenon and describes whether and how it might change in the future.
Forensic science has undergone dramatic progress in recent years, including in the areas of DNA collection and analysis and the reconstruction of crime scenes. However, too few professionals are equipped with the knowledge necessary to fully apply the potential of science in civil, criminal, and family legal matters. Featuring contributions from
