For nearly 15 years, Criminal Procedure: Principles, Policies and Perspectives (and softcover versions, Criminal Procedure: Investigating Crime and Criminal Procedure: Prosecuting Crime ), written by Joshua Dressler and George C. Thomas III, has sought to inspire students to analyze and critique constitutional and nonconstitutional criminal procedure doctrine. The book features careful case selection and editing that includes dissenting and concurring opinions when useful in understanding the law.
