I think we are completely at cross purposes. I was referring to death by police shootings across the ethnic divide, and what I said is supported by quantitative hard fact. Per million of the population shot by US police, 30 are black, 23 Hispanic, 12 white and 4 "other" - source
But my main point is not the ethnicity of those shot, it is the fact that so many of them (of various ethnicities) have been unreasonably shot. I mentioned this after the George Floyd killing, citing the fact that so many of those shot were originally stopped for very trivial reasons - Floyd himself apparently stopped for allegedly passing on a fake $20 bill. A few weeks later I back that up with another killing of someone who ended up being shot dead after going to sleep in a drive thru. I supplied a link to that case. Both these instances would be laughingly trivial, if it hadn't resulted in two deaths. Hence my conclusion that the US police are essentially out of control, and need reining in on shooting and their often fatal restraint techniques.
As far as Rayshard Brooks, the officer who shot him, Garrett Rolfe, has (rightly in my opinion) been charged with felony murder. You may think that shooting someone as they run away, having left their car behind, is justified, but I'm afraid I don't - and whether with or without a grabbed taser. At that point he was not a threat to the lives of the officers involved.
