Tldw...
In part 1, a "Trump supporter" is brought into the crowd from behind the police line and allowed to go into the crowd at the front. This person is clearly agitated and is over acting his role. He is among few who "break" the police line and then leads the crowd deeper inside the Capitol. He's wearing an ear muff cap.
In part 2, ear muffs guy again plays a central role being at the front of the crowd attempting to break down the doors where Ashli Babbit will end up being murdered moments later.
Weird.
