I don’t know the numbers, but from open source I suspect in any given year high tens to perhaps low hundreds of thousand of people are referred to it and engaged and we seem to have an attack every 18 months or so. Seems a tiny percentage to me. What would good look like to you? One attack per million referrals ? What are the success rates of similar de radicalisation programmes ( far right and so called Islamic) in other countries? Are they even smaller, do they approve say one attack per million? why are they better and what could we learn? What’s your personal estimate of the counterfactual? If we didn’t have prevent would there be less or more attacks and if more how many?
