All seemingly accurate and I agree with your assessments.
The guy got himself shot because he triggered an alert situation, and the officer was overly reactive from that point on. Not a time at all for a detainee to be doing dumb things like reaching for anything.
One question that has bugged me from the beginning is that I think we are all getting very used to inciting people starting their videos before an arresting officer (that means one who stops you) even comes close to the car. He is on camera from the first, so that we can all hear the excess use of an exaggerated use of "Sir" repeatedly uttered by the "victims."
But not an instant of that kind of almost standard response is recorded here. Or, WAS it recorded, and not shown..... erased, to start over, only after the guy got shot?
