Earlier calls for deeper focus on the intersection of the formulation and implementation of global counter-terrorism measures and civil society have gone largely unanswered. Seminal articles, chapters, and books laying the basis for such research remain relatively few in numbers and much of what is known can be extracted from grey literature and technical reports lacking theoretical rooting, methodological foundations, and little empirical evidence obtained through fieldwork and engagement with the actors implementing counter-terrorism measures, and the voices of those being targeted by those measures. This book, therefore, aims to better understand the relationship between the enforcement of global security measures linked to terrorism and civil society in a variety of countries around the world. It provides an entirely new foundation in a lagging research agenda concerning the relationship between post-9/11 counter-terrorism policies and measures and civil society.
