This book offers up-to-date information and guidance on the application of metrology in legal proceedings, clarifying the limits of validity of scientific evidence and presenting an illuminating series of case studies in which measurement uncertainty has played an important role. The fundamental concepts of metrology are discussed, and it is explained how metrology is capable of quantifying the reliability of measurement results and thereby contributing to appropriate decision making. With the aid of the presented case studies, this book will assist readers in understanding how legal decisions should be made in the presence of uncertainty. Areas covered in those studies include breath alcohol concentration analysis, and DNA profiling. Nowadays, decisions in most legal cases are based on evidence obtained through scientific analysis involving the acquisition of accurate measurements. Against this background, Forensic Metrology will be of value for lawyers and judges in both civil and common law countries, as well as engineers and other scientists with an interest in the subject.

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.

Integrity and honesty are the hallmarks of science - and especially so in the case of forensic science - making the study and practice of ethics essential to the field. Ethics and the Practice of Forensic Science, Third Edition directly addresses common stressors that can induce, or lead professionals - working in forensic laboratories, law enforcement, the judicial system, and at crime scenes - to commit misconduct. While forensic scientists, investigators, and experts are intrinsically ethical by nature, the reality is that these individuals face challenges including departmental or political pressures, lack of training, and conflicting standards. The difference, however, is that the work done by forensic professionals has the ability to compromise another person’s freedom, potentially leading to arrest, incarceration, and miscarriages of justice. Police and forensic professionals confront ethical dilemmas every day, some situations that fall within clear protocols or standards and others that frequently have no definitive answers. Ethics and the Practice of Forensic Science, Third Edition includes updated information and case studies, as well as recent research findings focused on ethics in forensic science. Chapters examine investigation and police culture through the lens of professional challenges, incorporating important information about the history of wrongful convictions, and including recent developments in overturned wrongful convictions, and the work of various innocence projects. Throughout the book, case examples of bias, ethical violations, and instances of tampering with evidence present the dangers of compromising one’s ethical standards. Through such cases, the book sheds light on the problem and offers alternative courses of action - presenting examples of what to do, and what not to do, when faced with ethical decisions in gathering, handling, analyzing, and presenting evidence.

All measurements are subject to error because no quantity can be known exactly; hence, any measurement has a probability of lying within a certain range. The more precise the measurement, the smaller the range of uncertainty. Uncertainty, Calibration and Probability is a comprehensive treatment of the statistics and methods of estimating these calibration uncertainties. The book features the general theory of uncertainty involving the combination (convolution) of non-Gaussian, student t, and Gaussian distributions; the use of rectangular distributions to represent systematic uncertainties; and measurable and nonmeasurable uncertainties that require estimation. The author also discusses sources of measurement errors and curve fitting with numerous examples of uncertainty case studies. Many useful tables and computational formulae are included as well. All formulations are discussed and demonstrated with the minimum of mathematical knowledge assumed. This second edition offers additional examples in each chapter, and detailed additions and alterations made to the text. New chapters consist of the general theory of uncertainty and applications to industry and a new section discusses the use of orthogonal polynomials in curve fitting. Focusing on practical problems of measurement, Uncertainty, Calibration and Probability is an invaluable reference tool for R&D laboratories in the engineering/manufacturing industries and for undergraduate and graduate students in physics, engineering, and metrology.

Forensic science has been under scrutiny for some time, since the release of the NAS report in 2009. The report cited the need for standardized practices and the accreditation of crime labs. No longer can the forensic community take the position that cross-examination in a courtroom will expose weaknesses in methodology and execution. Quality Management in Forensic Science covers a wide spectrum of forensic disciplines, relevant ISO and non-ISO standards, accreditation and quality management systems necessary in any forensic science laboratory. Written by a globally well-respected forensic scientist with decades of experience in the forensic science laboratory and on the stand, as an expert witness who is also a Fellow of both the Royal Society of Chemistry and the Chartered Society of Forensic Sciences. This book will be a must-have resource for all forensic science stakeholders, particularly law enforcement agents and lawyers less familiar with the impact of quality management on the reliability of scientific evidence. A comprehensive, multidisciplinary reference of scientific practices for use in the forensic laboratory Coverage from DNA to toxicology, from trace evidence to crime scene and beyond Extensive review of ISO and non-ISO standards, accreditation, QMS and much more Written by a foremost forensic scientist with decades of experience in the laboratory and as an expert witness
