This edition of Introduction to Criminal Justice: Systems, Diversity, and Change rep- resents a new and exciting adventure that explores uncharted territories and tech- nologies that will give you more insight about offenders and victimization. The book is designed to widen your perspective and challenge how you think about crime. This textbook and associated course is created to offer you the same sense of excitement and passion that has inspired our interest in the criminal justice sys- tem. Historical, contemporary, and, at times, controversial coverage of the crim- inal justice system represents subject matter that goes beyond the mundane in your college studies. The actual world of policing, corrections, and courts can be far more enticing than what is portrayed on the news or fictional crime shows. The real world of policy and how it impacts both the criminal justice system and everyone in society is shared. This textbook will ignite your interest in criminal justice and the wide variety of topics related to moral, ethical, and practical situa- tions that a large percentage of the population face daily.
