Update: Canada Admits Use of Undercover Cops During SPP Protest

"Quebec police admit they went undercover at Montebello protest"

From the article: "Police said the three [undercover agents] were told to monitor protesters who were not peacefully demonstrating to prevent any violent incidents, but they were called out as undercover agents when they refused to throw objects."

This is clearly false. Other protestors told the agent provocateurs to put down the rock and not start a riot. No one was goading the officers to start a fight. So, if the police are lying about the details of the incident, are they also lying about the purpose of the officers there?

For video of the incident and a good summary of the history of the use of agent provocateurs during anti-globalization protests, see here.
