This is a racist trope which is false and just shows that you can not be objective about this incident.

Look at the chart. Yes, black cops use their guns slightly more than white cops as an area gets a higher proportion of blacks. That's likely to be related in the increased violent crime in those areas.

But white cops are (on average) just shooting at or around black people for some other reason.

It is not the fault of Derek Chauvin or other whites that blacks like GF, or Mak’iyah Bryant or Ahmad Arbery commit crimes at much higher rates than whites.

The problem stems form the greater force used against blacks than whites when the other circumstances are the same.

Look, I know that about 99% of the muggings in America are commited by blacks [...]

About 52.7% in 2019.

[...] and that the majority of the victims are whites.

I can only find 20 year old data on that. But certainly most robbery victims in the US are white. (As are most people). But white people who were mugged by a single offender were more likely to be mugged by another white person than a black person. (About 40% of robberies and about 54% of robberies with white victims had a white robber).

Blacks have more confrontations with cops because blacks commit more crimes. You know that. I know that. Even black people know that.

And yet they proportion of those that involve being killed is still higher.

I think some of the interlocutors in this debate have lost all reason.

Certainly they've lost perspective.
