While gun design has undergone only minimal change over the centuries, investigative tools surrounding firearm use have grown significantly in sophistication. Now in its third edition, Firearms, the Law, and Forensic Ballistics has been updated to reflect recently published research and new technology developed since the last volume. Beginning with a discussion of the development of arms and ammunition from the fourteenth century to the present day, this book examines: Firearms laws around the world, including legal challenges raised in the U.S. by the Daubert decision Firearms manufacturing processes, the mechanisms of various firearms, and the linking of a particular bullet or spent cartridge with a suspected weapon The origins and development of new science in firearms, including controversies, pioneers, and an exposé of the "quack" purveyors of pseudo-science Internal, external, and terminal (wound) ballistics The nature, composition, and analytical detection of discharge residue left on a suspect The role of the ballistics expert at all stages of a case, ranging from the scene of the shooting incident, the post mortem examinations, the examination and testing of exhibits at the laboratory, and the presentation of evidence in court Recently introduced computer search techniques applied to captured and digitally stored images of marks left on fired bullets and spent cartridge cases Manual microscopic comparison work and computer-based searches on digital images of bullet and cartridge case marks to determine if a particular weapon has been fired in previous cases Written by an expert with more than 50 years of experience using and handling firearms, this text is enhanced with nearly 250 illustrations, making it a premier guide to the fundamentals of firearms and related evidentiary considerations.

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 scientists, law enforcement, and crime scene investigators are often tasked with reconstruction of events based on crime scene evidence, and the subsequent analysis of that evidence. The use and misuse of firearms to perpetrate crimes from theft to murder necessitates numerous invitations to reconstruct shooting incidents. The discharge of firearms and the behavior of projectiles create many forms of physical evidence that, through proper testing and interpretation by a skilled forensic scientist, can establish what did and what did not occur. This book is generated from the authors numerous years of conducting courses and seminars on the subject of shooting incident reconstruction. It seeks to thoroughly address matters from simple to complex in providing the reader an explanation of the factors surrounding ballistics, trajectory, and shooting scenes. The ultimate objectives of this unique book are to assist investigators, crime scene analysts, pathologists, ballistics experts, and lawyers to understand the terminology, science, and factors involved in reconstructing shooting incident events to solve forensic cases. The book will cover the full range of related topics including the range from which a firearm was discharged, the sequence of shots in a multiple discharge shooting incident, the position of a firearm at the moment of discharge, the position of a victim at the moment of impact, the probable flight path of a projectile, the manner by which a firearm was discharged and much more. UNIQUE FEATURES & BENEFITS: - The book is both a textbook for the student as well as a comprehensive reference book for an advanced forensic professional. - Explains topics in a logical sequence with an easy-to-follow explanation. - Numerous diagrams and photographs support the illustrate key concepts. - Case studies illustrate real-world application of technical concepts.
