The management of ideologically motivated offenders is not a new challenge for correctional administrators, nor is it unique to Islamist terrorism. The current over-emphasis on Islamist extremism has arguably provided an incomplete representation of the scope and considerations associated with managing extremists in the correctional environment. Furthermore, it has neglected emerging trends and future issues in the field, such as the re-emergence of politically motivated violence in Northern Ireland and right-wing hate groups. This chapter investigates the management practices specific to ideologically motivated offenders. It extends beyond that of Islamist terrorism to encompass a holistic view of the factors that are specifically relevant to the management of a range of radicalised offenders. It details the fundamental differences between this offender group and their mainstream criminal counterparts. Then it progresses to assess the strengths and vulnerabilities of various management models that range from isolation to dispersal. From this, conclusions are drawn which reflect the many facets of radicalisation and aim to guide correctional administrators and academia in the future directions for the effective management of ideologically motivated offenders in custody.
