This accessible yet comprehensive introduction to criminal justice in the United States has been dramatically updated and revised to include coverage of criminal justice's new, expanded role in the "war on terrorism" as well as to incorporate other recent developments, cases, and research in the field. Bohm and Haley have more than 50 years of combined experience teaching the introductory course and working in the criminal justice system--Bohm as a correctional officer and Haley as a police officer--and both continue to teach the course semester after semester at their respective universities.
