Joel Samaha is the best-selling author of three major textbooks in Introduction to Criminal Justice, Criminal Law, and Criminal Procedure. His success stems from his ability to present legal issues in a lucid and methodical manner. This text's success can be attributed to the author's ability to help the student grasp the complexities of the criminal justice system and the laws by presenting all sides of an issue equally. Samaha wants the students to understand why procedures are as they are instead of simply memorizing them. This is a comprehensive and legally-oriented text, focusing on the law as it is written, not solely from a layperson's point of view.
