In raw numbers, more whites are shot by cops than blacks. But blacks are only 12% of the population so a larger percentage of their population is getting shot. Blacks, however are committing a way larger percentage of violent crimes in relation to their percentage of the overall population; many, if not most of which, are on other blacks. It would be interesting to see how many blacks that violently resisted arrest did not get shot. I bet it would surprise you.

 As far as I know most of the guys on Minshall's "not bad due list" list did not resist arrest when they came for them. Would you have us believe that when Bill Jones was pointing his gun at the cop, the cop thought "lucky for him he's a white due or I would shoot back at him". The first option is to take the suspect alive. It prevents riots.  

As far as the guys in the helicopter ascertaining Crutcher was a bad due , they are trained to watch body language. much of that might be observable from a low flying helicopter.
