CEP Senior Advisor Ian Acheson writes: "On Tuesday, my organisation, the Counter Extremist Project, launches Hiding in Plain Sight – a discussion paper which I co-authored with a colleague from the European Policy Centre.

The paper is built on discussions between international experts from frontline practitioners to clinical psychologists to propose ideas for strengthening our protective services to detect and defeat what we call “disguised compliance”. In other words we wanted to know what more could be done to test the authenticity of the relatively small number of terrorist offenders if and when they say they have recanted a commitment to violence."
