@Chillkroete77 you claimed earlier that I denied police brutality. I have believed that US cops were exceptionally bad by global standards since the 1980's when multiple immigrants from the Soviet Union complained to me that US cops mistreated them in ways that Soviet cops never dared to. I have thought the US needs police reform decades before BLM was founded.
Regarding population size: yes, on a per capita basis, black MEN (but not black women) are about twice as likely to be mistreated. However, according to a study cited earlier in this thread by someone else, white and black cops are about equally likely to act badly. Also, if adjustments are made for economic background, the race difference disappears, but the gender difference remains. So the real story is that US cops OF ALL RACES are unusually bad to civilians OF ALL RACES, and the cops discriminate mainly on the bases of class and gender, much more than on the basis of race. Still, even middle class white women are in more danger from the cops in the US than in any other developed country.
