The Fifteenth Edition continues to include all the material required to master the essential issues that arise in both state and federal criminal cases. The book's comprehensive coverage of constitutional, statutory, and ethical rules regulating the criminal process has made it one of the few textbooks that students over the years have opted to keep as a reference for their work as prosecutors, defense attorneys, and judicial clerks. The new edition also continues the custom of incorporating the most thoughtful and provocative commentary available. The authors bring together the latest statistics, relevant legislative trends, and insightful policy and scholarly debates, facilitating critical analysis of the process and its potential reforms. This unique and always up to date framing of the issues has made the book the nation's premier text for teaching criminal procedure year after year.
