The only fake thing is the staging of the people behind the cordon so that the location is visible. I don't see anything to suggest CNN brought the Muslims along, gave them placards or told them what to say, unless I am missing something. I get the point that they are choosing to push a narrative and there is an element of staging for the camera but I am pleased to see some Muslims are prepared to publicly condemn the actions of other Muslims and to see this on TV.
Don't get me wrong - Muslims should be challenged about their faith and their inability to get a handle on extremism but the last thing our communities need is more hatred and division from the media.
