What is your proposed solution?
For what it’s worth, black men kill more cops than cops kill unarmed black men.
It’s tragic, but many orders of magnitude away from your claim.
It’s not the quantity that makes it horrible, tragic, and infuriating. It is all those things because it’s evidence of a larger systemic issue which includes lots of other awful things that fall short of homocide; and it’s largely unnecessary.

Regarding your second claim, I can't find those numbers. The closest thing I can find is this newsweek piece [2] with data from 2013 and 2014. That suggests most people who kill police are white. But it also includes prison guards as police.

You're right the quantity isn't specifically important but it does illustrate that there is a problem. Even if it is not the #1 cause of death it is disproportionately higher.
