Stop him? I'd say they had reason to talk to him, no more than that (AFAIK without audio)
Attempt to restrain him? Not sure without the audio. If he was being belligerent, then maybe so. If he was being generally cooperative, then the attempt to restrain was unreasonable.
Agreed...
However, his attempt to flee was an ill-advised over-reaction, at best, and easily seen as threatening, given he was clearly carrying.
Also agreed, though being ill-advised, or an over-reaction, or even seen as threating doesn't mean he is intending to or being a threat. I mean if they weren't cops, there is no way anyone would be arguing his actions weren't reasonable, would there? I don't think that difference is thee difference between totally reasonable and so unreasonable it's acceptable to be killed over.
Draw on him first?
Yes, the cop had his gun out and pointed while the dead guy's was still holstered.
The video did not show any officers with drawn guns before he pulled away and attempted to flee.
I didn't say that.
Given that they were clearly LEOs vs. just an old somebody on the street, and the police did not appear to point a gun at him until he attempted to flee, the situation does not quite fit the presented straw-man in key ways. Regardless that, even in a perfect world, there's right, and then there's dead right. Better to have kept it calm on the street, and killed them in court, figuratively speaking.
Figuratively speaking. Exactly.
Why is it that police are given such broad leeway on the use of force because they have to make split second decisions, yet at the very same time the people they interact with are expected to make absolutely perfect decisions or risk having their lives ended? That is a very extreme discrepancy.
