So the radicalisation comes from where?
a) corrupt religious leaders
b) internet groups and propaganda
c) feeling segregated and attacked
you don't need the religious leaders to be corrupt in order for them to be radical - they can be quite sincere in their beliefs
yes material on the internet can radicalise people
but in this instance I'm referring to being locked up with a bunch of people already radicalised when you're on the edge - that can probably do more damage in terms of radicalising those individuals than internet videos or even hate preachers
