I think they know. I think this is part of their way of destroying the prosecution's case and exposing the staged event. The Dems planned this all out, including creating the 'evidence' they would use in the impeachment trial. That evidence could only be created by knowing participants. Scripted words. Scripted acts. Hired guns. MAGA costumes. Faked deaths. Pre-planning. Carefully edited story-lines. It's all there and just needs to be presented by the Dems before it's pulled apart by the defense and shown for what it is.
