While in Plato's time there may have been some truth to his belief that there can only be one single justice, and one single law, such is not the case today. Criminal justice systems vary widely across the world in their approaches to the problem of crime. This book presents the theme that a country's legal model to a great extent determines the character of its police and corrections as well as its legal system. Itexamines these different systems and is a useful reference guide for all criminal justice professionals.Abstract: Examining different types of criminal justice systems and the legal models that shape them, this work uses examples to highlight five basic legal foundation models: continental, common law, Islamic,Marxist, and mixed. It explains how these legal models dictate the roles of the police, courts, and corrections systems in various countries.
