This video shows three police in Montreal pretending to be ‘black block’ anarchists at a nonviolent action and how they are uncovered and exposed (with rock in hand!).
Great response and excellent leadership as a union leader stands up to them and defuses the situation, isolating them from the rest of the group and clearly marking them out until they become exposed as agents provocateur. It’s blown up on the national news in Canada.
It’s been talked about for years that police do this to incite riots – and everyone knows it happens all the time, but it’s incredibly hard to prove unless you can isolate them like this and get some kind of proof.
