A lot of people here seem to think that it would somehow be impossible for a bunch of actors to stage this whole thing (with fake blood, and everything else), but I don’t see why that would be impossible. I still have an open mind about it, and will weigh all evidence I see as it becomes available, before coming to a complete, definitive personal conclusion about it.
People's perceptions of any event that ever happens, usually differ widely, and perceptions are often notoriously wrong (and that also applies to viewers of videos, such as this one, or the videos of the shooting of JFK, for example). Those mutually exclusive perceptions can't all be right.
Not one thing that happened there that day at the Capitol, was impossible to fake. (Can you think of one thing there that could not be faked? Can actors use fake shouting, and fake motions? Can fake blood be caused to "gush", like they often do in fake movies? Can someone take a fake shot at someone, just like Clint Eastwood, or John Wayne did so often?)
Some people, of course, "know it all", and so they can't be bothered to take the prudent step of saying they can't be totally sure about something until more facts are available. (Of course, those witnesses to Christ's crucifixion knew it all too. Too bad, it eventually became crystal clear that those eyewitnesses were 100% wrong.)
