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.
