This revised edition has been completely updated and expanded to address the latest developments and professional concerns in forensic medicine. There are new chapters on the medical aspects of police restraint and new material on the potential of police exposure to infection, the role of alcohol and drugs in vehicular accidents, and forensic sampling in sexual assault examinations. The chapters on fundamental principles, nonaccidental injury in children, and the care of detainees are all fully revised, as are the appendices (now containing a list of useful websites).
