This chapter examines post-arrest experiences, preventive detention, prison conditions, and rehabilitation programmes. It analyses how detention without trial, limited procedural safeguards, and institutional opacity shape perceptions of injustice and distrust. Drawing on interview data, the chapter explores physical and psychological trauma, health concerns, and the limits of religiously centred rehabilitation. It argues that incarceration under counter-terrorism regimes produces long-term consequences that extend beyond confinement and directly affect reintegration prospects.
