He did call. You can see him doing so. I’ve watched it several times and don’t think he did anything wrong. The guy got out behind him and he drew his weapon. This guy was leaving. Whether he decided “I guess I better stay in the car”, or “I’m getting out of here”, who knows but the cop could have at least pulled him out of the road after he fell down.
“He did call”
You point that you have made in at least two posts about the cop’s atempt homicide of the citizen is really an important one.
