Look at the channel this comes from:

I live in Quebec and in August 2007 one branch of our police force did a false flag operation to discredit protesters and legitimize the use of force on civilians. They got caught by pacifist protesters who noticed the boots of the undercover cops were wearing the same boots as the police force: https://www.youtube.com/watch?v=St1-WTc1kow
The police force then mistranslated the events by saying that the president we see in here asking the cops to "drop the rocks" saying that the president and others were asking them to "throw the rocks". I have no trust in anything coming from my government anymore.
You know who got reprimanded for using provocateurs? No one!
Similar techniques were used at the G20 and the media is playing right into the government's hands.
