I read today she hadn't turned it on. She was on her way to a domestic dispute when she came upon Crutcher's car in the middle of the road.
Since she parked well to the right of the suspect’s car, it is unlikely it would show anything useful. Her light bar was on, so the camera was likely on. I do recall the police chief saying that he was releasing the video from the other cops in the area, even if it didn’t show anything, since he figured the public records requests were going to ask for it anyway. So the video from her car should be out there although the link for the Public Affairs office appears to be broken.
Tulsa and Charlotte are textbook examples on how do it right, and how to do it wrong. Charlotte probably needs to look for a police chief that isn’t an affirmative action hire.
