I watched a video which was supposed to show him doing that, but all I saw was him prancing around the police in an alcove area with a bunch of people, and the cops finally taking him down. I never saw him changing his clothes. He still had the Pirelli shirt and Fargo hat when they restrained him. I'd like to know if he was even arrested. I bet not.
She also detailed the black guy who was recording the whole thing, who later appeared on CNN as a witness to the events. That guy at one point put on a gas mask while he was recording with a selfie-stick held high. She then showed that same guy at a prior Antifa rally holding a bullhorn.
I saw the earlier video with a guy with a scraggly beard inside the Capitol also with a gas mask. A woman with a bullhorn was giving instructions through a broken window to "take the building." In the Yon interview, I saw a still photo of that same scraggly-beard guy standing at the door before he entered the Capitol.
For a supposedly spontaneous "Trump-supporter riot," there were certainly a lot of suspicious-looking people at the front of the crowd who were the first to enter the Capitol.
