The local news guys kept calling them “Black Rock”.
“It started off with lots of signs and kids yelling and then the Black Rock group came in and started taking down the barricades and throwing rocks....”
Just like the sixties and I imagine every protest. Some people get together to voice their opinions and the communists come in to stir it all up. BLM, Immigration, Women’s march - they all have some printed signs with www.revcom.com on them - The Revolutionary Communist.
Take advantage of a “crisis” and make it worse.

I believe the term you are looking for is “Black Bloc” ...lots of info on the Internet regarding this. Wikipedia likes to describe it in terms of a reactive “tactic.” I would describe it more as a loosely aligned grouping of violent anarchist and communist agitators.
Very similar to the groups that ravaged European society in the 1930’s and led to the emergence of the Brown Shirts as a response.
