Constitutional principles are the foundation upon which substantive criminal law, criminal procedure law, and evidence laws rely. The concepts of due process, legality, specificity, notice, equality, and fairness are intrinsic to these three disciplines, and a firm understanding of their implications is necessary for a thorough comprehension of the topic. This book examines the tensions produced by balancing the ideals of individual liberty embodied in the Constitution against society’s need to enforce criminal laws as a means of achieving social control, order, and safety.

This book examines and explains how the exclusionary rule undermines the purposes of the criminal justice system, increases crime rates, dispenses unequal justice, and encourages police corruption. Professor Signorelli uses concrete examples and cases to demonstrate the connections between the rule and its problematic consequences. The book explains how unequal treatment of defendants, denial of justice to crime victims, and perjury by police officers to circumvent the rule taint the criminal justice system, and how a tainted justice system spreads ill effects throughout society.
