In recent years, the use of illegally produced firearms has increased exponentially worldwide. These are often cheap, nonstandard firearms that defy known classification and identification criteria. The use of unusual firearms in crimes has frequently led to unpredictable and misleading reconstruction of shooting incidents. In this book, internatio
The updated second edition of Handbook of Firearms and Ballistics includes recent developed analytical techniques and methodologies with a more comprehensive glossary, additional material, and new case studies. With a new chapter on the determination of bullet caliber via x-ray photography, this edition includes revised material on muzzle attachments, proof marks, non-toxic bullets, and gunshot residues. Essential reading for forensic scientists, firearms examiners, defense and prosecution practitioners, the judiciary, and police force, this book is also a helpful reference guide for undergraduate and graduate forensic science students.
Forensic Ballistics in Court: Interpretation and Presentation of Firearms Evidence is an accessible introduction to firearms and ballistics evidence and how this is analysed and presented as evidence in a court of law. The book approaches the subject in terms of the realities of case work, opening with a clear and illustrated explanation of the correct nomenclature for various weapon types and their parts. Ammunition is also extensively covered, again with annotated illustrations. Basic external and terminal ballistics, wounding capabilities are likewise covered to give an overview of the subject. A key aspect of the book covers the theory and philosophy behind striation matches and the associated statistics, how positive matches should be peer reviewed and the importance accreditation has on this subject. Gunshot residue formation and identification and the various methods used in its analysis are reviewed in depth. This includes a critical examination of the pros and cons of each type of examination and the evidential weight which can be applied to each method. Accessible and reader-friendly introduction to firearms and ballistics. Clarifies the limitations of firearms evidence. Extensive use of global case-studies throughout. Focus on the interpretation and assessment of the weight of firearms/ballistics evidence presented at court. Covers the importance of witness and accused statements and their interpretation in relation to the investigation under review. Includes coverage of gunshot residue collection, examination and interpretation and the potential for contamination of GSR samples. Includes numerous real life case studies that the author has dealt with over the past 45 years. Takes an applied approach to the subject.
Written by the nation's foremost authority on gunshot wounds and forensic techniques as they relate to firearm injuries, Gunshot Wounds: Practical Aspects of Firearms, Ballistics, and Forensic Techniques, Second Edition provides critical information on gunshot wounds and the weapons and ammunition used to inflict them.

Outstanding Academic Title, Choice Magazine The staggering toll of gun violence—which claims 31,000 U.S. lives each year—is an urgent public health issue that demands an effective evidence-based policy response. The Johns Hopkins University convened more than 20 of the world's leading experts on gun violence and policy to summarize relevant research and recommend policies that are both constitutional and have broad public support. Collected for the first time in one volume, this reliable, empirical research and legal analysis will help lawmakers, opinion leaders, and concerned citizens identify policy changes to address mass shootings, along with the less-publicized gun violence that takes an average of 80 lives every day. Selected recommendations include: • Background checks: Establish a universal background check system for all persons purchasing a firearm from any seller. • High-risk individuals: Expand the set of conditions that disqualify an individual from legally purchasing a firearm. • Mental health: Focus federal restrictions on gun purchases by persons with serious mental illness on the dangerousness of the individual. • Trafficking and dealer licensing: Appoint a permanent director to ATF and provide the agency with the authority to develop a range of sanctions for gun dealers who violate gun sales or other laws. • Personalized guns: Provide financial incentives to states to mandate childproof or personalized guns. • Assault weapons and high-capacity magazines: Ban the future sale of assault weapons and the future sale and possession of large-capacity ammunition magazines. • Research funds: Provide adequate federal funds to the Centers for Disease Control and Prevention, National Institutes of Health, and National Institute of Justice for research into the causes and solutions of gun violence. The book includes an analysis of the constitutionality of many recommended policies and data from a national public opinion poll that reflects support among the majority of Americans—including gun owners—for stronger gun policies.
Firearms, the Law, and Forensic Ballistics, Second Edition offers a comprehensive reference on the forensic science of firearms. It describes what happens when a weapon is fired in terms of internal, external, and terminal/ wound ballistics, and discusses the consequences for the forensic scientist both at the scene of the shooting and in the labor
This excerpt from the “masterful, timely, data-driven” study of the gun control debate examines the potential of stronger purchasing laws (Choice). As the debate on gun control continues, evidence-based research is needed to answer a crucial question: How do we reduce gun violence? One of the biggest gun policy reforms under consideration is the regulation of firearm sales and stopping the diversion of guns to criminals. This selection from the major anthology of studies Reducing Gun Violence in America presents compelling evidence that stronger purchasing laws and better enforcement of these laws result in lower gun violence. Additional material for this edition includes an introduction by Michael R. Bloomberg and Consensus Recommendations for Reforms to Federal Gun Policies from the Johns Hopkins University.
This is a guide to recommended practices for crime scene investigation. The guide is presented in five major sections, with sub-sections as noted: (1) Arriving at the Scene: Initial Response/Prioritization of Efforts (receipt of information, safety procedures, emergency care, secure and control persons at the scene, boundaries, turn over control of the scene and brief investigator/s in charge, document actions and observations); (2) Preliminary Documentation and Evaluation of the Scene (scene assessment, "walk-through" and initial documentation); (3) Processing the Scene (team composition, contamination control, documentation and prioritize, collect, preserve, inventory, package, transport, and submit evidence); (4) Completing and Recording the Crime Scene Investigation (establish debriefing team, perform final survey, document the scene); and (5) Crime Scene Equipment (initial responding officers, investigator/evidence technician, evidence collection kits).
