This Special Issue on ‘Policing Terrorism and Radicalism’ for the Pakistan Journal of Criminology brings together a wide and diverse range of researchers, academics and practitioners from around the world. This Special Issue contains a balanced mix of theory and practice that will resonate with anyone wanting to know and learn more about the complexities which underpin the twin brothers of terrorism and radicalism. The diversity of the articles is such that I have thematically arranged them, somewhat loosely; around three key notions associated with policing terrorism and radicalism – namely, assessment, cyber space and investigations.
