In the third edition of Essential Criminology, authors Mark M. Lanier and Stuart Henry build upon their critical review of criminology, expanding their coverage of the multifaceted “Crime Prism,” adding boxed readings by both international theorists and students, and identifying the six fundamental world changes that are altering the way we think about crime. By reframing crime and its control in the context of global interdependence, the communications revolution, and changing perceptions of national security, the authors ask: what kind of criminology is needed for the twenty-first century? With cutting-edge updates and illustrative real-world examples of everything from Blackwater to government surveillance and Lombroso’s legacy to the global spread of disease, this text is a necessity for both undergraduate and graduate courses in criminology.
