I think this is the MO of Muslim Terrorists. If they’re in jail they might as well recruit other future and fledgling terrorists. Those in jail are upset at the world and think that the world is the one who got them there so why not join a group that will teach the establishment and government a lesson. What’s so interesting about Islam is that it is the only religion that focuses on just “getting them in the door” because once you’re in you can only leave by death.
