This interactive criminal law casebook continues the tradition of our prior criminal law casebook (which went through four editions), but enhanced that tradition by moving to an interactive format. As with the prior books, our primary goal is to create a "teacher's book"-a book that contains thought provoking problems (referred to as "hypos" in the Interactive Casebook Series) designed to stimulate thought and produce interesting classroom discussion. The hypos are woven throughout the chapters and are designed to help students learn doctrine, illuminate trends in the law, and ultimately produce better learning. A secondary goal was to include a focus on teaching "skills." Some of the problems place students in practical situations that they are likely to encounter in practice, and therefore encourage students to think about how they might handle those situations in real-life.
