Excerpt:
Muslim patrols stalking British streets could become "a lot more dangerous" and perhaps even willing to maim or kill, the head of an anti-extremism organisation has warned.
As British jihadists venture abroad to capitalise on the aftermath of the Arab Spring and then return to the UK, they are likely to bring a greater level of violence back home, Maajid Nawaz, the chairman of the Quilliam Foundation, suggested.
His comments follow incidents in which groups of Muslim vigilantes, dubbing themselves 'Muslim Patrols' have approached Londoners and demanded they behave in an Islamic way by not drinking.
