This casebook provides the most comprehensive treatment available, including the theoretical foundations, the common-law origins, the statutory structure, and the procedural context of modern criminal law. The book concentrates on doctrinal materials that can support both rigorous technical, and sophisticated theoretical, discussions. The purposes and limits of punishment are addressed through Supreme Court decisions, a focus on statutes throughout the substantive law sections enables training students in the legal art of statutory interpretation as well as exposing them to the hard moral and political problems of legislative choice, and the sentencing materials reprise the theory of punishment in the context of the practically most important stage of the modern process. The chapters on sentencing and on criminal procedure are updated to reflect developments in the U.S. Supreme Court, and the sections on complicity and conspiracy, intoxication, and insanity have been overhauled for greater clarity.
