What & Who discovers terrorist plots?

[davidbfpo]

Jason Burke, in The Observer writes again on the 'first line' of defence in CT, after the recent attacks in the UK and his article ends with:

The only way potential attackers will be identified before they kill and maim is through the most old-fashioned means one can imagine: someone warning authorities about what they plan to do. This can be people in the workplace, the mosque, or at school. Research tells us that more than 70% of Islamic militants who operate alone tell someone of their plans. The first line of defence against Islamic militancy is not our crash barriers or covert operations, nor armed cops or MI5, it is a potential terrorist’s brother, mother, partner or friend.
