The youtube video at  http://www.youtube.com/watch?v=gAfzUOx53Rg&mode=related&search= is a TV report on the Surete de Quebec finally admitting after 4 days of denials that 3 men posing as 'black bloc' protesters at the SPP protest at Montebello Quebec. At 3.07 pm eastern standard time, the CEP (communications union) President Dave Coles confronted 3 men who had been pointed out by other bloc-ers as police, two had identical bandanas on, one had a rock in his hand, all three were riot-squad sized and looked really uncomfortable. when challenged, they stuck in a group, pushed back, and refused to de-mask or to confirm they were police (they have to in UK, unless that's just hearsay?). They eventually backed up to a line of riot police, and then pushed a little to get arrested. Another youtube vid shows the riot gas exchanges that happened later as protesters refused to be penned in a field as a protest zone, and approached the front gates. the voiceover says that 4 were arrested, and shows the undercover cops being lead away, so maybe there was only one legit arrest? For the full film of the identification, see  http://www.youtube.com/watch?v=St1-WTc1kow . Another 'vid' shows the 3 on the floor, and the soles of their boots have a distinctive yellow hexagon on, identical to those on one of the 'arresting' cops.

you couldn't make it up. such amateurism. The most ludicrous aspect is probably the denials.

The SPP was a 'summit' complete with security fence and over-policing, between US, Canada and Mexico (Mexico cut out of some of the talks, of course), that was described as a 'dialogue'. Even after the failures of NAFTTA etc to create an all-america economic agreement, they keep pushing...
