There were three guns pointed roughly at her. Two from Capitol security agents (plainclothes) barricaded inside the chamber and pointing out the broken window. Those were handguns. Behind her, a tac’d-out Capitol cop with an AR. Popular opinion is that it was a handgun from inside. A pede took a dramatic photo through the glass of the plainclothes guy drawing on him, he says just before the shot was fired. Note that the crowd had been let it, almost led up to the chamber as another video posted here shows, and was unarmed. Her death is inexcusable. The vote count should not be continuing now, and I will not forgive the Congress for these things. Mike Pence is particularly responsible as president of the senate.
