As our understanding of genetics increases, its application to criminal justice becomes more significant. This timely book examines the use of genetic information both in criminal investigations and during the trial process. It discusses current scientific understanding and considers some potential legal, ethical and sociological issues with the use of genetic information.The author draws together debates from scientists, ethicists, sociologists and lawyers in order to understand how the criminal justice system currently reacts, and ought to react, to the new challenges presented by genetic evidence. She asks the important question of where priorities should lie: whether with society's desire to be protected from crime, or with an individual's desire to be protected from an unwanted intrusion into his or her genome. Topics include rights of privacy and consent in obtaining DNA samples, evidentiary issues in court, the impact of genetic evidence on punishment theory and sentencing, and genetic discrimination. This book will be of use to criminal and medical law students, along with academics, practitioners and policymakers interested in exploring the various criminal law issues in relation to genetics. It will also be of interest to criminal justice, philosophy, ethics, sociology and psychology students and academics looking explore the legal issues involved in such a topic.
