Heres some footage of some undercover cops being called out at a recent protest in Canada. They were intentionally going to assault their fellow officers so that there was an excuse to violently attack the other protestors. They get yelled down by some union guy. too funny.

Its hilarious how they pretend to get arrested.

Also pay close attention to news articles about these protests. I've already heard 2 on the radio calling areas where police and protestors scuffled "illegitimate protest". This is one nice orchestrated event.

Goddamn kops don't have enough to do without trying to stir up even more shit?
