Exclusive: Sophisticated analysis says there is no single pathway to violent extremism: MI5 has concluded that there is no easy way to identify those who become involved in terrorism in Britain, according to a classified internal research document on radicalisation seen by the Guardian. The sophisticated analysis, based on hundreds of case studies by the security service, says there is no single pathway to violent extremism. It concludes that it is not possible to draw up a typical profile of the “British terrorist” as most are “demographically unremarkable” and simply reflect the communities in which they live. The “restricted” MI5 report takes apart many of the common stereotypes about those involved in British terrorism. They are mostly British nationals, not illegal immigrants and, far from being Islamist fundamentalists, most are religious novices. Nor, the analysis says, are they “mad and bad”. Alan Travis reports.
