The weird echo chant isn’t only happening in Atlanta. I’ve seen it popping up among these nutjobs a lot lately.
Even 100 morons versed in the game can take over a group. Nobody else has the "stage" or the bull horn or the ready plan to control the speech.
The bearded bullhorn guy had on a red t-shirt with the old SDS black fist logo, but with two fingers up like a peace or victory sign. Anybody known his group? There were several "wardens" in the crowd in red shirts. They were visually watching the leaders and exchanging overhead hand signals, like across-crowd semaphore. So even in a loud, unruly environment, the crowd is managed in a controlled way by the leadership via the "wardens."
There was even a big dude in a t-shirt that literally said, "Union Thug" like he was proud of it. He moved around with a red-shirt dude to get in the face of anybody from out of the group who wanted to speek.
This was all about the control of speech. It's their blueprint for crowd control. Not sure if it works at any other level.
Kind of reminds me of the mob in Rome. Thumbs up and the christian lived, thumbs down and well you know.
