This collection of previously published work on security and rights focuses on the appropriate relationship between rights and what we can think of as counterterrorism policy. Such a focus might seem both necessary, because of 9/11, and unfortunate, because there are other causes of insecurity besides terrorism. However, the intensity of the 'war on terror' has created an ongoing surge of scholarship on the relationship between security and human rights that either has indirect implications for debates about security where terrorism is not in issue, or has directly led to an attempt to rethink more generally the idea of security and its relationship to rights.
