One thing that I find disturbing, though I think I can see the rational, is that the officer that fired the fatal shot that killed Ashlii Babbitt has not been named. The video showing her climbing through a window with no weapons in her hands, the pop pop of the gunshots and her falling back into the crowd is chilling. For all that, I can't condemn the officer for firing. He was put in an impossible situation. He should not be ridiculed for doing his duty. The police investigation cleared him and that should put an end to the story.
Something that has to be considered ... is that, ultimately, it was the actions of the Capitol police, ... that kept every US lawmaker from harm that day.
Although most of the assembled protestors were peaceful, ... a small minority perpetrated actions ... which showed that they had the potential to inflict harm to certain lawmakers ... if they had gotten their hands on them.
Within any group of that protestors that size, there are protagonists who will go too far ... and will egg the crowd with them to go too far.
This is illustrated in the terrible visuals of the scaling of the Capitol walls, ... and some of the reported defilement of the Capitol premises.
A few of the protestors brought firepower.
A few of the the protestors were responsible for the deaths and injuries of Capitol defenders that day.
A few of the protestors would have, likely, gone beyond the true wishes of the crowd ... if they had gotten their hands on Pence, or Pelosi, or AOC, ... or Rep. Omar, etc.
These kind of things can get out of hand pretty easily. It just takes one (or more) crackpots. And there were a few crackpots present that day.
