Indonesia hosted the third meeting within the Global Counterterrorism Forum (GCTF) Detention and Reintegration Working Group in Medan, Indonesia. The meeting, titled “Workshop on Capacity Building and Training for the Appropriate Management of Violent Extremist Offenders,” was co-chaired by Indonesia and Australia and co-organized by the Global Center. It focused on the importance of dynamic security and effective interaction and engagement strategies and methods to monitor and prevent radicalization to violent extremism within the prison system. Building on the GCTF Rome Memorandum on Good Practices for Rehabilitation and Reintegration of Violent Extremist Offenders, the presentations and roundtable discussions centered on good prison standards and practices and the necessity to build professional, positive relationships based on trust between prison officers and violent extremist offenders as a means to ensure institutional order and safety, prevent recruitment and the spread of radicalization within the prison system, and facilitate the implementation of rehabilitation and reintegration programs. The meeting was attended by 63 participants from 23 countries and nine organizations.
