Public Security in Federal Polities is the first systematic and methodical study to bring together the fields of security studies and comparative federalism. The volume explores the symbiotic relationship between public security concerns and institutional design, public administration, and public policy across nine federal country case studies: Brazil, Canada, Germany, India, Mexico, South Africa, Spain, Switzerland, and the United States. In addressing specific national security concerns and aspects of globalization that are challenging conventional approaches to global, international, regional, and domestic security, this volume examines how the constitutional and institutional framework of a society affects the effectiveness and efficiency of public security arrangements. Public Security in Federal Polities identifies differences and similarities, highlights best practices, and draws out lessons for both particular federations, and for federal systems in general. This book is essential reading for scholars, students, practitioners as well as policy- and decision-makers of security and federalism.
