Written by active researcher and bestselling author, Frank E. Hagan, Introduction to Criminology, Ninth Edition is a comprehensive introduction to the study of criminology, focusing on the vital core of criminological theory-- theory, method, and criminal behavior. With more attention to crime typologies than most introductory texts, Hagan investigates all forms of criminal activity, such as organized crime, white collar crime, political crime, and environmental crime. The methods of operation, the effects on society and policy decisions, and the connection between theory and criminal behavior are all explained in a clear, accessible manner. All statistics, tables, and figures have been updated, as have the photographs, supplements, and audio and video packages in the new edition to make the material most relevant for your course.
