This textbook is a testament to the fact that Richard Bonnie is truly one of the giants in the field of criminal law. Everything this man writes is valuable; the chapters on mental health and insanity alone make purchasing this book worthwhile (Bonnie is an expert on the insanity defense). This book definitely leant itself to rich and provocative classroom discussions. I enjoyed the book almost as much as I enjoyed his class. I would recommend this text to any professor who is interested in spicing up his or her criminal law classes.
