What does Prevent do to turn people away from extremism and terrorism? Can they really deradicalise someone who is of that sort of mindset? My question is prompted by the news today that apparently the killer of David Amess MP was dropped from the programme too quickly. How long would someone normally stay in the programme? And would Prevent have made any difference to Axel Rudakabana - he was referred to them 3 times but each time Prevent closed the referral. What happens to someone that Prevent can't deradicalise, do they go on a security service watch list?
