I agree. But, with all of the fuss we've heard about law enforcement not recording to the max in criminal encounters, I'd hope they were a bit careful here. This was a high-profile situation, although the protesters were white and the situation wasn't an LEO quick-response to a crime in progress.
I feel the Sipsey Street Irregulars warning was likely heeded.
Anyways, the only way I would believe the Feds went Gestapo is if there are NO dashcams or recordings of the event, including from those apprehended.
THEN I would know this was a Feral Fascist Government move.
