This constitutional law text focuses primarily on the Fourth Amendment (reasonable search and seizure) and the Fifth Amendment (double jeopardy, testifying against oneself), since they are the most relevant to criminal justice issues. Harr and Hess, authors of several successful texts in the areas of criminal procedure, criminal justice employment, and policing issues, have taken the most complex of material and made it into a student-oriented, manageable text that covers the key issues related to our Constitution and the criminal justice system.
