Is DNA technology the ultimate diviner of guilt or the ultimate threat to civil liberties? Over the past decade, DNA has been used to exonerate hundreds and to convict thousands. Its expanded use over the coming decade promises to recalibrate significantly the balance between collective security and individual freedom. For example, it is possible that law enforcement DNA databases will expand to include millions of individuals not convicted of any crime. Moreover, depending on what rules govern access, such databases could also be used for purposes that range from determining paternity to assessing predispositions to certain diseases or behaviors. Thus the use of DNA technology will involve tough trade-offs between individual and societal interests.

This book, written by a distinguished group of authors including U.S. Supreme Court Justice Stephen Breyer, explores the ethical, procedural, and economic challenges posed by the use of DNA evidence as well as future directions for the technology. After laying the conceptual historical, legal, and scientific groundwork for the debate, the book considers bioethical issues raised by the collection of DNA, including the question of control over DNA databases. The authors then turn to the possible genetic bases of human behavior and the implications of this still-unresolved issue for the criminal justice system. Finally, the book examines the current debate over the many roles that DNA can and should play in criminal justice.

andquot;Leaders in the field take the reader through a wide spectrum of critical issues involving DNA applications in the criminal justice system. This book is not only the most valuable reference for forensic practitioners but is essential for the law-enforcement and academic communities as well.andquot;

andldquo;This book provides a rich compendium of fully up-to-date law and policy analysis, coupled with an accessible scientific narrative. It is a striking achievement, and I expect to refer to it often and with confidence that current trends, views, and perspectives, as well as the evolving state of our knowledge of legal and scientific issues relevant to criminal justice, has been amply presented.andquot;
