Man, I already showed where cops have been admitted to being used in canada, the 'photo-op' anarchist in london throwing the brick through the window, I hadn't shown the video of the 3 'anarchist' cops at the g-20... they got called out as cops by the protestors themselves... and other videos where they made up a game called 'anarchist or cop' like 'duck duck goose'. Hell, going back to the canadian example, the person coming out and admiting the potential provocateurs (the only guy at the protest to pick up a rock) as being "standard practise world wide" in terms of infiltrating protest groups.
The facts are that if the cops do get arrested that are provocateurs they are quickly released and replaced. That's not to say that there aren't real anarchists, that honestly believe that no government would be ideal and they get brought into the idea of 'tearing it down', those are the groups that are infiltrated by cops.
I've backed it up enough I think... if you want I could also throw in examples from : Geneva, Melbourne, Bamff, etc... Like seriously, if you still deny that cops are the main cause of the violence at most every protest then nothing will convince you... but I'm sorry it's a fact, I've backed it up I can show many more examples... and I can also quote "Standard police practise worldwide" what part did I NOT make clear yet??

There may be exceptions to the rule, but the violence is not from the core of the protestors, except where they get dragged into mob mentality OR retaliate ... Like this woman :

Who it later turned out was not even interested or involved in the protest, she just got trapped at the wrong place when the police shut the doors on the protestors.... naturally it would take me showing EVERY clip taped and you'd still say I'm lying or something when saying the cops went over-board at the g-20...
