This book examines the question of whether justice or security is the primary virtue of 21st-century society. The issue of enhancing security without undermining justice - managing risk without undermining the rule of law - has always been problematic. However, recent developments such as new counter-terrorism measures, the expanding scope of criminal law, harsher migration control and an increasingly pronounced concern with public safety, have posed new challenges. The key element of these contemporary challenges is that of membership and exclusion: that is, who is to be included within the community of justice, and against whom is the just community aiming to defend itself? Justice and Security in the 21st Century brings together researchers from various academic disciplines and different countries in order to explore these developments. It attempts to chart the complex landscapes of justice, human rights and the rule of law in an era when such ideals are challenged by increasing demands for efficiency, effectiveness, public safety and security. This edited volume will be of much interest to students of critical legal studies, criminology, critical security studies, human rights, sociology and IR in general.
