What strikes me about this thread and particularly those posts that are saying the report is accurate, is that everything is hearsay. "I have heard" this or that. Evidential references to non-extreme right wing sources might make the story more credible.
i live in London and, yes, there was a "sharia law London" sensationalist story around the time that UKIP were campaigning for support but surprise surprise those stories have disappeared. And it was nothing to do with this refugee crisis.
I'm sure there are problems and tensions in some areas. There are bound to be. These people have fled horrific situations and are probably very disturbed. I haven't heard of a rush to buy guns to defend ourselves. But that's not to say it doesn't happen in some places and probably says more about the way the situation is being managed than anything else.
And to those saying we should mind our own business and let the Middle East countries sort out their own problems, I'm afraid that door closed a long time ago. Arguably we would not be having this very crisis if we had kept our noses out of other countries control of their own oil supplies and hadn't tried to topple dictators under the guise of "doing the right thing" but really for our own interests.
We in the west did a lot to create the current problems that these people are fleeing. Yes I'm sure Isis will use the situation to infiltrate but our leaders made our bed and so we have to lie in it unfortunately.
