My take on Babbitt is, what she did was wrong. The problem there is that Byrd was both incompetent and a coward. Byrd's overall record as a Capitol Police officer shows his incompetence clearly. That he was unwilling to step into the hallway and confront Babbitt, who wasn't looking at him (unlike Good who clearly saw the officer in front of her vehicle), and didn't see him, is on Byrd.
Byrd should have tried less than lethal force first. That's my argument with Babbitt. She put herself in a position where she could get shot and did. That's on her. Byrd shouldn't have been let off the hook for incompetence however. He had the time to make choices and work towards non-lethal outcomes. Babbitt was not an immediate threat to anyone or thing.
Good put herself in a position where she could get shot and did. That's on her. The officer who fired on her had every right to do so in that split second he had to make a decision in. He may have made the wrong call, but he made a call, and it was valid, nonetheless.
