This really, really makes me angry.

Quebec provincial police admitted Thursday

...after denying it for 24 hours...

that their officers disguised themselves as demonstrators during the protests at the North American leaders summit in Montebello, Que.

"In no time did the police of the Surete du Quebec act as instigators or commit criminal acts," the news release states in French.

Well, actually, the press release says a bit more than that. What it says is:

Les policiers ont été repérés par les manifestants au moment où ils ont refusé de lancer des projectiles.

In english thats: "The police officers were located by the demonstrators when they refused to launch projectiles." The word "lancer" means to throw aggressively or launch. Now, in the video, it is extremely clear that the protesters are not telling the cop to launch the rock. They are telling the cop to put the rock down, and they are identified as cops because they refused to put the rock down. The cop even violently shoves the person who is telling him to put the rock down. There really is absolutely no question about that. Which, in turn, leaves little doubt that the Quebec police are complicit.
