Question Part 4:
It seems like the photographers planned to be inside the building before the protesters, perhaps both Antifa and/or Trump Supporters entered into the building? There's appears to be more camera photographers than the police? And almost as many photographers as the protestors.
The riot looks, especially from the photographs and video of a typical PLANNED BAIT and SWITCH Tactic by ANTIFA....
Or, better, a luring of Real Trump Supporters into the Capitol Building via Adolf Hitler and Joseph Goebbels Tactics to get photos and videos of Real Trump Supporters inside the Capitol Building, to deceitfully, show Real Trump Supporters are violent (when they are being mislead).
