Expert evidence presents a number of challenges to the legal system: how can the courts ensure that the scientific evidence they admit is reliable? How should statistical evidence be presented to juries? What aspects of human nature should experts be allowed to testify on? How can the effects that adversarial tactics have on expert witnesses be restrained? This book explores these questions. Drawing on work in psychology, the philosophy and sociology of science, probability theory, forensic science, as well as on a broad spectrum of legal writings, Redmayne suggests how the challenges of expert evidence can be met.

Forensic work occurs across the criminal justice sector and the legal and health professions and intersects with work in a range of areas, such as child protection, family welfare, mental health, offending, disability and addictions, family violence programmes, juvenile justice and sexual assault centres. This book offers contemporary perspectives on forensic policy and practice from the range of practitioners working with people within the forensic domain and canvasses ideas about risk and offending behaviours together with ideas about effective responses to rehabilitation and recovery. The contributors to this proposed book are drawn from the practitioners, policy contributors, advocates and researchers in mental health, welfare, law, criminology, policing and health. Negligible attention has been paid to forensic policy and practice; this proposed book offers cross-national attention to how mental health, welfare and justice systems intersect, who they affect, and how practitioners structure effective responses for vulnerable people within the forensic domain. A particular strength of the book is its international focus, making it relevant to academics and practitioners who work in this field around the world.

Edited by a world-renowned leading forensic expert, the book is a long overdue solution for the forensic science community.

Forensic practitioners work in a diverse range of settings, with a wide variety of groups and with a large number of agencies. Their work, whilst rewarding, is challenging, demanding and often undertaken in highly stressful situations. Ensuring that the workforce is trained and supported is essential in order to maintain skilful, knowledgeable, responsive and effective practitioners. Whilst training, self-directed learning and peer support all play a role, the need for supervision for practitioners is increasingly being recognised. This text is aimed at all those working in forensic settings who have direct contact with the perpetrators and victims of crime and is written for both those new to supervision and those with many years' experience. Specific chapters focus on knowledge and skills for the supervisor and the supervisee and on those responsible for developing supervision systems for staff groups. This includes a focus on risk, boundaries, approaches to learning and the evidence base for supervision practice. Attention is also given to developing supervision competence and combatting harmful or 'lousy' supervision. The core text is supplemented by ten Special Topics addressing single issues commonly faced in supervision practice, such as ethical issues and reflective practice. The combination of comprehensive chapters and a focus on specific issues through ten Special Topics provides those involved in supervision with an essential resource. This book is essential reading for supervisors, students, managers and researchers who are involved or interested in the supervision process.

All microbes, including bacteria, viruses, and fungi, can be classified and identified by matching a few peptides known to be unique to each organism. Identifying Microbes by Mass Spectrometry Proteomics describes ways to identify microorganisms using powerful new techniques combining hardware and software and yielding highly accurate methods for detection, identification, and classification of microbes. This straightforward technology can be used to detect unknown and unsequenced microorganisms as well as microbes in complex environmental samples. This book reviews various mass analyzers used for detection and describes ionization methods frequently used for analysis of microbial constituents, a necessary step in the preparation of mass spectrometry (MS) samples. The text also discusses diverse processing methods, which are used to analyze MS files for matching mass spectral profiles, and examines protein and nucleic acid sequence-based methods capable of classification and identification of microbial agents. The book also covers sample collection methods and specific sample preparation techniques. The text addresses using computer software and bioinformatics approaches for data mining to discriminate microbes using mass spectrometry proteomics (MSP). It also discusses historical pattern recognition-based methods and other approaches such as analysis of pyrolysis products, chemical ionization (CI) of fatty acid methyl esters, and MALDI-MS. The text contains examples of the application of the MSP technique for microbe detection and includes a survey of suitable and commercially available MS-based platforms. Successful applications include the identification of unknown microbes in honey bees associated with colony collapse disorder and the analysis of virus strains from the 2009 influenza pandemic. The final chapter outlines future trends in these groundbreaking uses of MS techniques, which are fast, not limited by sample type, and show potential in answering complex environmental questions.

The criminal profiling community can easily be split into two separate groups: those that have written criminal profiles and those that have not. It is an important distinction, because report writing is one of the most important requirements of good scientific practice. The process of writing up findings helps to reveal flaws in an examiner's logic so that they can be amended or revisited; the final report memorializes findings and their underlying basis at a fixed point in time; and as a document a forensic report provides the best mechanism for transparency and peer review. The problem is that many criminal profilers have not written criminal profiles, and still more prefer that this remain the case, often to conceal their lack of methodology. The contributors to this volume have travelled the world for more than a decade to lecture on the subjects of crime scene analysis and criminal profiling. The result has been a steady stream of requests from educational institutions and government agencies alike to teach the application of criminal profiling theory. Everyone has read the books, everyone has attended the lecture; but few have experience with hands on practice and application. In other words, there is a growing number of serious professionals who want to know how to put theory into practice and then learn what it means to put their findings into written form. Behavioral Evidence Analysis: International Forensic Practice and Protocols has been written as a companion text to Turvey's Criminal Profiling, now in its fourth edition. It is meant to provide the legion of instructors that are teaching criminal profiling as a subject with real world examples of case reports. It is also meant to serve as a desk reference for professionals that are writing crime scene analysis and criminal profiling reports, to enable sampling of structure, terminology, and references.

Using Forensic DNA Evidence at Trial: A Case Study Approach covers the most common DNA analysis methods used in criminal trials today, including STR techniques, mitochondrial DNA, and Y-STRs. It presents some novel techniques-including familial testing and analyzing domestic animal hair-that have been recently introduced in unique cases, each of which is outlined in detail. It also illustrates special issues related to forensic DNA evidence by using court proceedings such as trials and appeals, commissions of inquiry, and government and laboratory reviews. With forensic DNA analysis becoming increasingly important at trial, the lively and sometimes bizarre cases presented in this book have been carefully chosen to highlight specific concepts, methods, and interpretations used in DNA analysis. Sections throughout examine the nature of expertise with a special focus on the role of subjectivity in the interpretation of forensic DNA evidence, emphasizing cognitive bias and extraneous context. Using both convictions and exonerations as examples, the book also discusses the strengths and limitations of DNA evidence and testing. The book is written in an accessible manner for the non-scientific reader, such that criminal lawyers, judges, and forensic experts will all understand the nature of analysis and application of DNA evidence in a variety of court cases. Extensive references-including notable trial proceedings, cross references of cases, and specific forensic statistics-round out the book and help to provide a complete understanding of forensic DNA analysis and its current usage in the courtroom.

How and when did forensic science originate in the UK? This question demands our attention because our understanding of present-day forensic science is vastly enriched through gaining an appreciation of what went before. A History of Forensic Science is the first book to consider the wide spectrum of influences which went into creating the discipline in Britain in the first part of the twentieth century. This book offers a history of the development of forensic sciences, centred on the UK, but with consideration of continental and colonial influences, from around 1880 to approximately 1940. This period was central to the formation of a separate discipline of forensic science with a distinct professional identity and this book charts the strategies of the new forensic scientists to gain an authoritative voice in the courtroom and to forge a professional identity in the space between forensic medicine, scientific policing, and independent expert witnessing. In so doing, it improves our understanding of how forensic science developed as it did. This book is essential reading for academics and students engaged in the study of criminology, the history of forensic science, science and technology studies and the history of policing.

Relationship Inference in Familias and R discusses the use of Familias and R software to understand genetic kinship of two or more DNA samples. This software is commonly used for forensic cases to establish paternity, identify victims or analyze genetic evidence at crime scenes when kinship is involved. The book explores utilizing Familias software and R packages for difficult situations including inbred families, mutations and missing data from degraded DNA. The book additionally addresses identification following mass disasters, familial searching, non-autosomal marker analysis and relationship inference using linked markers. The second part of the book focuses on more statistical issues such as estimation and uncertainty of model parameters. Although written for use with human DNA, the principles can be applied to non-human genetics for animal pedigrees and/or analysis of plants for agriculture purposes. The book contains necessary tools to evaluate any type of forensic case where kinship is an issue.

This book is a scholarly work of forensic linguistics that demonstrates how the principles of Gricean pragmatics and their recent elaboration in Information Manipulation Theory (IMT) can be of use to courts faced with deciding cases of allegedly fraudulent disclosure documents. The usual goal of legal rules for disclosure documents is not merely to prevent lying but other forms of deception as well. In particular, the goal of these rules is to force the communicator to reveal information that could cause material harm to certain receivers, harms that the communicator, for various reasons of self-interest, might prefer to keep secret or hidden. Because IMT and the Gricean framework have seldom been used in published studies to investigate legally mandated disclosure documents aimed at laypersons, this book seeks to enrich current explications of the rhetorical "workings" of deceptive disclosures within the broader Gricean tradition of pragmatics. The book questions the fundamental relationships among Grice's maxims as well as the much circulated notion that violation of some maxims is more deceptive and more immoral than violations of others. In addition, the book also attempts to show how various other theories and research in discourse linguistics and reading comprehension can be used to support IMT analyses in addressing the discourse processing issues unique to legally required disclosure texts. In this way the book contributes to the larger dual mission of the field of forensic linguistics, which is both to understand and to improve courts' impact on social justice.

The ability to thoroughly and accurately photograph a crime scene is a mandate for all investigators, regardless of the time of day, weather conditions, or confines within which a piece of evidence is concealed. Evidence is commonly found in some of the most difficult to access and photograph locations. Having the knowledge, wherewithal, and skills necessary to photograph evidence in less-than-accommodating environments is vital to a photographer's effectiveness and success. Advanced Crime Scene Photography, Third Edition takes a somewhat different approach to the subject over prior editions. Rather than assuming a crime scene investigator's or photographer's comfort with the operation of their cameras-and a basic understanding of apertures, shutter speeds, ISO values, and basic exposure calculations-the author provides a thorough review of basic photographic concepts, as a refresher to readers. And, for those less familiar or otherwise new to photography, such background provided makes the foundational concepts more understandable for those readers who require such information to understand the more advanced techniques covered later in the book. In addition to this added coverage, an entirely new chapter has been added to provide essential guidance on how to prepare and testify in court. Anyone with a camera phone can take a photograph in perfect lighting, with the subject sitting out in the open, and already positioned for the best composition. This book provides crime scene photographers the skills to record those same beautiful photographs in adverse condition, surrounded by tragedy, utilizing all the tools available to the investigator. The greatest tool a photographer has available to them is their brain. From start to finish, the value of quality crime scene photographs cannot be overemphasized; photographers must take control of their photographic endeavors, identify the challenges, design a plan to capture the image correctly, and then execute that plan. As such Advanced Crime Scene Photograph, Third Edition is written to help photographers achieve the goal of capturing the best possible images, especially in those difficult-to-capture, real-world environments and conditions. All photographers need to practice their craft, whether they are actively working cases as seasoned veterans or are just beginning their careers. This book provides the knowledge and skills essential to achieve career and professional success in crime scene photography.

Traumatic Brain Injury: Methods for Clinical and Forensic Neuropsychiatric Assessment, Third Edition provides physicians and psychologists with a scientifically based schema for the clinical evaluation of traumatic brain injury (TBI). The book assists physicians and psychologists in developing treatment plans for patients who have sustained TBIs and also guides those providing forensic analysis to lawyers, insurance bodies, workers' compensation systems, triers of fact, and other stakeholders in the adjudication of victims of TBI. The procedures and recommendations in this book are grounded in highly referenced evidence-based science but also come from more than 5000 cases wherein the author and contributors have personally examined individuals who have sustained a TBI, or who claim to have sustained a TBI. This edition has been entirely rewritten. The style now follows a more traditional neuropsychiatric format than previous editions. Since the last edition, there has been increased awareness and scientific study regarding the effects of blast brain injury as a consequence of US military experiences in Afghanistan and Iraq. There is also increased interest in the phenomenology of mild traumatic brain injury and, in particular, the forensic complications associated with evaluations of this disorder. Chronic traumatic encephalopathy has also received significant scrutiny in the last decade, possibly associated with sports injuries. This book is a comprehensive resource for clinicians treating patients as well as for forensic specialists. Its purpose remains the same as in prior editions-to provide physicians or psychologists with a practical method for an effective evaluation of TBI based upon known scientific principles of brain-behavior relationships and state-of-the-art clinical, neuroimaging, neuropsychological, and psychological techniques.

Suspect Families is the first book to investigate the social, political, and ethical implications of parental testing for family reunification in immigration cases. Drawing on policy documents, legal frameworks, case study material and interviews with representatives of governmental and non-governmental organisation and immigration authorities, immigration lawyers, geneticists and applicants for family reunification, the book analyses the different political regimes and social arrangements in which DNA analysis is adopted for decision-making on family reunification in three distinct European countries: Austria, Finland and Germany. Interdisciplinary in scope, the book reconstructs the processes, institutional logic and the political and administrative practices of DNA testing from a comparative perspective, combining theoretical conceptualisation with detailed empirical work to explore the central societal, political and ethical issues raised by the use of DNA profiling in the context of immigration policy. A ground-breaking study of the role played by new technologies in migration decisions, Suspect Families will appeal to scholars of sociology, political science, science and technology studies and surveillance studies.

Miscarriages of justice are a regular occurrence in the criminal justice system, which is characterized by government agencies that are understaffed, underfunded, and undertrained across the board. We know this because, every week, DNA testing and innocence projects across the United States help to identify and eventually overturn wrongful convictions. As a result, the exonerated go free and the stage is set for addressing criminal and civil liability. Criminal justice students and professionals therefore have a need to be made aware of the miscarriage problem as a threshold issue. They need to know what a miscarriage of justice looks like, how to recognize it's many forms, and what their duty of care might be in terms of prevention. They also need to appreciate that identifying miscarriages, and ensuring legal remedy, is an important function of the system that must be honored by all criminal justice professionals. The purpose of this textbook is to move beyond the law review, casebook, and true crime publications that comprise the majority of miscarriage literature. While informative, they are not designed for teaching students in a classroom setting. This text is written for use at the undergraduate level in journalism, sociology, criminology and criminal justice programs - to introduce college students to the miscarriage phenomenon in a structured fashion. The language is more broadly accessible than can be found in legal texts, and the coverage is multidisciplinary. Miscarriages of Justice: Actual Innocence, Forensic Evidence, and the Law focuses on the variety of miscarriages issues in the United States legal system. Written by leaders in the field, it is particularly valuable to forensic scientists and attorneys evaluating evidence or preparing for trial or appeal in cases where faulty evidence features prominently. It is also of value to those interested in developing arguments for miscarriage in post-conviction review of criminal cases. Chapters focus specifically on issues of law enforcement bias and corruption; false confessions; ineffective counsel and prosecutorial misconduct; forensic fraud; and more. The book closes by examining innocence projects and commissions, and civil remedies for the wrongfully convicted. This text ultimately presents the issue of miscarriages as a systemic and multi-disciplinary criminal justice issue. It provides perspectives from within the professional CJ community, and it serves as warning to future professionals about the dangers and consequences of apathy, incompetence, and neglect. Consequently, it can be used by any CJ educator to introduce any group of CJ students to the problem.
