This chapter presents assembling suspicion as a technique of diffuse securitising and it's unbinding of security. It introduces Ericson and Haggerty's work on policing as risk communication, and explores a process of diffuse securitising that challenges exceptionalist securitising as well as the understanding of policing as social control. The chapter discusses a form of policing that securitises by enacting flows of risk information. In 1997 Richard Ericson and Kevin Haggerty published an influential book Policing the risk society. It drew attention to a range of policing practices that in the understanding of policing as a coercive practice of social control, sustaining public order and crime control disappear in the background. Instead of rendering suspicions through the creation of statistical probabilities translated into algorithmic connections, one seeks to pre-empt rather than prevent criminal practice. Assembling suspicion is a continuously developing process characterised by relatively small changes and adaptations.
