What & Who discovers terrorist plots?

[davidbfpo]

A BBC report on a current trial of a Muslim convert who was radicalised quickly and left for Syria - where he was stopped and returned to the UK. It appears he had an arranged Muslim marriage, who disliked his extremism and told someone and two undercover MI5 agents become his trusted friends.

It almost fits what the UK's most senior CT police officer referred to in a Q&A:

Q: Police now work closely with MI5, sitting, literally, alongside them, so you’re getting all that intelligence. But is it harder to counter the threat from lone actors, because, by definition, they are loners and are working alone?
A: Well you can get intelligence about loners but it comes from different sources. So many of the lone actors have at some stage in their radicalisation connected into extremist groups in this country; or connected online to some of the propaganda being put out by Isis and other groups. So that gives us opportunities but also, of course, intelligence comes from communities. So, we’ve got examples where an escalating threat from lone actors has been spotted first by someone in the community who’s picked up the phone to us and that makes a difference. So when I talk about a “whole system effect”, I think expecting a small group of a few thousand police officers and security service officials to be able to solve this is not realistic. We will do everything we can to improve but we’re going to need that wider input from public and other agencies.
