Terrorism is considered extraordinary crime, therefore, Indonesian government issued Law No. 15 of 2003 and Law No. 9 of 2013 and formed Detachment 88 Anti-Terror Unit (Densus 88 AT). Terrorism is driven on the basis of ideology so that Densus 88 AT employs de-radicalization in handling the terrorists and former terrorists. De-radicalization aims to change radical ideology. Most of the terrorists and former terrorists who have been deradicalized do not change their radical ideologies easily. The former terrorists instead commit to terrorism over and over again by recruiting new members found in correctional institutions.
