How Muslims are expected, nay required, to police their own communities

This is now standards in Western societies: that Muslims are required in return for tolerance toward them to police their own communities and to point out the trainers and dangerous elements among them.  Imagine if this is said, say, about the Jewish communities. That would be classified rightly as classical anti-Semitic: the typical anti-Semitic view that the Jewish citizenship in Western societies is conditional on good behavior and conduct.  And the beauty is that in all Arab American and Muslim American conventions and conferences, the FBI and Department of Homeland Security send officials to speak to those members and to urge them to intensify their police work of other Muslims.  And the audiences cheer as if the visits by government security officials is an honor for the audiences.
