This sixth edition of a textbook expands, clarifies, updates and further illustrates the basic principles included in the preceding edition. Updated and expanded explanations of some of the more complex topics also are included. Emphasis has been placed on using examples based on actual court cases without burdening the student with numerous case citations. By using the facts of documented criminal appeals decisions, more emphasis has been placed on defining differences among the States in their treatment of various issues. The text is divided into 21 chapters, ranging in topics from the historical background of criminal law, matters affecting criminal responsibility, crimes including homicide, sex offenses, robbery, and arson, traffic offenses, to organized crime. A glossary and index are included. Questions for discussion and suggested readings follow each chapter.
