The casebook covers all of the foundational constitutional criminal procedure cases, as well as the most recent decisions from the United States Supreme Court on the subject. In addition, it includes a number of forms, examples, problems, and questions to help students fully appreciate key principles. Although it addresses more, the book focuses on the Fourth Amendment search and seizure provision, the Fifth Amendment protections against unlawful confessions, and the Sixth Amendment right to counsel. The materials effectively cover recent Supreme Court cases analyzing searches of smart phones, searches by canine officers, and issues of "standing" that determines who may effectively complain when police violate the Constitution.
