  • Walter P. Signorelli, JD
    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.
    Walter P. Signorelli, JD
    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.
    Walter P. Signorelli, JD
    This book illustrates how and why attorneys are winning an increasing number of unwarranted lawsuits against the police. This concise and practical guide discusses how these lawsuits have negatively impacted police morale and effectiveness, and how police departments both small and large can work to reverse this dangerous trend.

    Officers throughout the United States and perhaps internationally have heard use of force instructors discuss the "21 Foot Rule" during their officer safety, firearms and deadly force training. As both a use of force instructor and practicing forensic police practices expert, I have also trained and testified to this concept myself.

    On a hot July day, fire and police are called to the home of a 55 year old man suffering from heat stroke. Police arrive first and find the man sitting on a bench in his front yard. When the officers approach the man and ask him to give them his cane, he becomes agitated and non-compliant. One officer suddenly grabs the cane away from the man, who screams and suddenly stands up. The man is tased, taken to the ground, beaten and handcuffed. He is transported to the hospital where ER physicians confirm a diagnosis of heat stroke. The man has no criminal history. He sustains numerous moderate injuries which keep him from returning to work for several weeks. The officers and agency are sued and settle out of court.

    A facts-based introduction to the controversial and militant Black Lives Matter political organization and movement written by a nationally renowned forensic criminologist who has been involved in many of the nation's most publicized police-involved death cases. Learn about the movement's founders, ideology, funding sources, surrogates, radical goals and objectives to disenfranchise law enforcement and usurp the rule of democratic law. Several infamous police death cases forensically explained and numerous false narratives of the movement are factually destroyed with explanations of the actual circumstances. This is a powerful, vetted "go to" reference source for researchers, the media, law enforcement and those interested in this radical movement.
