emmie - // so who thinks they can be rehabilitated, one does. //
I think the notion of rehabilitation in any case is laudable, but I also think that in the case of Jihadists, the chances are seriously reduced, and more importantly, the risks involved in proving that rehabilitation is successful, i.e. release back into society, is simply too great to be justified - as has been evidenced by recent events.
For people to die in order to demonstrate that rehabilitation has failed is a concept that cannot be countenanced.
Those terrorists who believe they are living and breathing the will of Allah will see themselves as martyrs on earth, happy to remain incarcerated until they die of old age, and those that are genuinely mentally ill are sectioned along with any other psychopath representing a clear and present danger to the public.
