Am watching this new film on the Security and Prosperity Partnership and the protests against it which took place on August 20, 2007 during the SPP summit in Montebello.
Very interesting segments on the police presence at the protest and the way the riot police were managed. Sounds like the protesters were penned in like cattle, in which case there was no need ever to use pepper spray or tear gas.
Every Canadian should watch this video. It was uploaded to Google Video on July 2nd and has been rated five stars, with 185 ratings so far. (107 minutes)
