I have tracked down the left-wing activist, who went to the police on 7th January about the shooting he witnessed at the Capitol, was on CNN that evening, and has since been arrested. He clearly isn't a Trumpist, and he was certainly filming throughout events there.
The fact that looking for "left wing" and "activist" and "Capitol" finds precisely one person's name in all of Hannity and the rest's comments is clearly of interest. Let's see, how many thousand was that crowd estimated to contain? And they have located a whole one of them who wasn't there to support Trump? Wowsers.
Oh, and the CNN videographer Jade Sacker, who was with him observing, makes two, if we assume CNN are Antifa. (Or BLM. Or whatever other organisation we use as a boo-word.) I am not sure whether she has yet been arrested for filming though.
