This is exactly what happens when the filthy globalists that "run" the world get together. It happened in Pittsburgh last year.
It's the cops dressed as "anarchists" that perpetrate the violence so the peaceful protesters can be attacked.
WATCH AT 0:45.....all the plainclothes people running in that pack, and being let behind the line, are cops--including the black-clad 'anarchist' !!!! BTW, watch out for the old white-bearded flannel shirt cop and the famous 'scary lady' cop.
