A collection of works, some previously published as articles in the journal Police Practice and Research, this book provides both conceptual analysis and case studies, exploring historical and sociopolitical contexts of conflicts in order to help readers better understand these themes. The book defines the concepts of terrorism and radicalization, discusses countering terrorism through intelligence gathering, and examines different policing models. The conclusions drawn from these findings may assist in combating terrorism and political violence around the world. This book is a co-publication with the International Police Executive Symposium (IPES).
