I mean the Proud Boys basically issued a press release saying they would be disguising themselves as Antifa so the left could be blamed.
And we know for a fact the same was done at the BLM protests. With the perpetrators of the Police Station arson that practically everyone on the right pointed to as proof of left wing violence turning out to be well known leadership of right wing militia groups.
This is just that particular football getting fumbled. They’re trying to make that the story even though the attempt already failed.
