The British police are resorting to systematic provocation in their bid to give an excuse to the government to enforce an all-out ban on peaceful protests across the country.

A video shot of the recent anti-government protests in London on November 9 has been published on the You Tube site, showing two plain-clothed guys have a brief word with uniformed officers before storming into the crowd, barging into a young guy, spinning him around and lashing out at him.
As it is shown in the video, then a uniformed officer approaches and they flash a warrant card behind their back. The uniformed officer turns away, and the two so-called ‘Agents Provocateur’ escape into the crowd.
The crowd shouts ‘agent provocateur’ and points as they make their way pushing through, the video shows.
