The European Commission-funded Radicalisation Awareness Network Prison & Probation Working Group is meant to prevent radicalisation in prison and during probation. In prison and probation programs, radicalisation and deradicalisation meet. Sentenced radicals can either be determined to be faithful to their ideology, consider quitting their radical activities or want to withdraw from a radicalised group. Also, there is the risk of other prisoners being recruited and radicalised during their stay in prison, given particular conditions of such confinement., The aim of RAN P&P is to gather practitioners working within prison or probation programs to exchange experience and interesting practices between the various existing programs, specifically on:, RAN P&P had its first meeting on 19-20 November 2012 in Vienna with 60 participants. Practitioners from prison and probation services of 26 Member States attended. Promising practices were presented and discussed. The two day conference initiated a network, to explore the European landscape of prison and probation in relation to (de)radicalisation and to exchange lessons learnt on the ground. The following paper outlines some of the core policy recommendations of the Working Group.
