This is a video clip from the Occupy Atlanta protest which is an off-shoot of the Occupy Wall Street protest
This method of communicating is freaky and somewhat disturbing. Orwellian brainwashing comes to mind. I saw video of the same kind of thing with the Occupy Wall Street group in NYC. The national media is not showing any of this stuff. I hazard a guess that if they did, support for this lunacy would dry up in a matter of hours.
Update: Redstate blog has an update that desctibes the weirdness shown in the video above. It is as I had feared. Read the whole thing.
