"Going to Extremes"

This sounds like a reasonable approach to me but of course there are some vociferous detractors.

From Foreign Policy...

Nearly a decade after 9/11, this thinking has evolved into one of Britain's most promising counterterrorism strategies -- and perhaps its most controversial. The government is, in effect, betting that the ideology that so many Islamist radicals claim to believe in can be employed to keep them from becoming terrorists in the first place.

Hard-line mosques like Brixton have often been the last stop before radicalism for people like Moussaoui and Reid. But mosques generally don't know what to do with such young men, especially if they stop short of openly advocating violence. The usual response is to expel them. But once they're out the door, they may be gone for good.

In this dilemma, Baker saw an opportunity. In March 2007, he launched the Strategy to Reach, Empower and Educate Teenagers (STREET), a center near the Brixton Mosque aimed at young Muslims. Operating on a shoestring budget, STREET offers mentoring for thousands of drop-ins and recently released Muslim convicts, helping with schooling, job training, and anti-violence counseling. If a STREET drop-in mentions an al Qaeda propaganda video he has seen, counselors watch it with him, pointing out the fallacies in its interpretation of Islam. STREET's mostly Salafi staff members are credible to their audience because they are like them -- indeed, several were once in their shoes. "If they cannot relate to you," says Baker, "if your lifestyle doesn't resonate, they will not accept anything from you."
