BLM doesn't form protests when black men are killed by black cops. They are politically savvy and understand that the optics of that aren't conducive to their message. In fact, they don't appear to care at all about non black people killed by police either. The 76 percent of people killed by police that aren't black don't interest them.
The real danger to black men in USA is being murdered by a non cop. Black men are insanely overrepresented in both homicide victimization and perpetration.
It should be noted that southern whites in the USA had massive rates of homicide until the early 20th century. They have significantly higher rates of violence compared to northern whites even today.

I don't know if this includes deaths by things like choking or beating.
If this is correct, death by cop is actually pretty rare. Not bitten by shark rare, but maybe in the magnitude of fatally falling off a ladder rare.
Which of course isn't to say harassment or abuse by cop is also rare. Nor to say there isn't racial disparity because the chart clearly shows there is.
So it’s around 20-100x more per capita than it could be.
In the United States when you look at the data that is posted in my previous comment you will see that the vast majority of police shootings involve an armed suspect.
However even if you only look at data on unarmed suspects I highly suspect that the US has a higher per capita rate than either Germany or Poland.
