Part of the endgame of an entitlement culture - same thing happened in Greece, but at least they waited until the cuts actually happened. The wankers in England are rioting because the cuts in entitlements were announced.
The "official" excuse is the killing of a guy by police. The leftoids in the UK are blaming Cameron's announcement of cuts of course.
Immigration is a part of it, but I saw one report where Turks in one section banded together and kept the riots out of their area.
Weak police force, more concerned with "feelings" rather than doing actual police work. Like shooting rioters torching stores with people in it.
Anarchists - the modern violent kind, not the more intellectual kind that sits around sucking up the benefits of a Capitalistic society while disdainfully decrying Capitalism - or any -ism for that matter. No, these modern anarchists love to create mayhem and cause damage. And they are allowed to - see previous comment re' police.
I saw a map of the London area, there were well over 2 dozen incident flags - and that is just London. It's spreading to other cities as well. People have been saying London was the most violent, dangerous city in the "civilized" world - and damned if they weren't right.
I gotta go find that wanker on another board who haughtily told me that London was perfectly safe, the reports of the violence were all overblown.
