There are no studies that show that police kill blacks at a higher rate then whites.
Have you ever heard of Tony Timpa or Duncan Lemp? Doubtful even though you'll say you have.
You don't hear about them because the media is responsible for the manipulation that makes you believe that cops kill blacks on a daily basis.
Super late, but...

Police kill blacks at a rate about double their share of the population. They kill whites at about 3/4ths their share of the population. Latinos are about equal. "Other" has all the usual problems with Other but I would not be at all surprised to hear Native Americans are killed at rate far above their share of the population.
So yeah, about half or slightly less than half of those killed by cops are white, as a function of whites' larger share of the population. If you are concerned about them, then the right answer is to show solidarity with BLM and leave the nuanced class-based critique to Adolph Reed.
Also, Duncan Lemp was a *** but he would still be alive if no-knock raids were not permitted, which...is one of the explicit goals of these protests, vis a vis Breonna Taylor.
