Canada: Quebec police admit to infiltrating SPP protest
The Surete du Quebec has admitted that the three "black bloc"-style protesters at the recent Security and Prosperity Partnership meeting in Montebello were in fact police officers as a union leader has previously claimed. However, the Quebec police claim that they weren't there as "agents provocateurs" but were in fact there to prevent violence. For the backstory, see Les agents provocateurs at SPP protest in Canada?
In related news, the North American Union apologists entry has been updated.
UPDATE: Even if you support police going undercover at protests, and even if you support them posing as black bloc members rather than, say, hippies, it's a bit difficult to support the fact that one of the cops had a rock in his hand. While he never used it, why did he have a rock in his hand? For that extra touch of the echt?
