Challenges for effective counterterrorism communication: Practitioner insights and policy implications for preventing radicalisation, disrupting attack planning and mitigating terrorist attacks

Growing concerns about small-scale, low sophistication terrorist attacks, and the difficulties they present for security services, make public coproduction of security increasingly necessary. Communication to ensure that the public(s) is aware of the role they can play will be central to this. This article, based on interviews with thirty expert practitioners, explores challenges associated with communication designed to prevent radicalization, interdict attack planning and mitigate the impacts of a terrorist attack in the United Kingdom and Denmark. The interplay between these challenges and the contemporary terrorist context are analyzed, highlighting that new, or adapted, communications and approaches may be necessary.
