This text presents a broad overview of the criminal justice system in the United States. "Introduction to Criminal Justice" has been updated to include a new chapter on the issues and ethics of policing in the United States, expanded features that foster Web research, and critical thinking activities. A hallmark of Glencoe postsecondary texts, "Introduction to Criminal Justice" now features critical thinking exercises in different venues and formats to facilitate a more flexible learning approach. Students will develop their understanding of criminal justice by acquiring a basic knowledge of the law and legal theories. Building on this foundation, the special features then provide essential exposure to practical issues, and develop personal and critical thinking skills to prepare students to deal with situations and dilemmas they could encounter in their Criminal Justice careers.
