Question

how were the African-Americans ill-treated?​

Answer 1

Answer:

available for incidents in which the police shoot and kill people show that for African-Americans, there's a much higher chance of being fatally shot relative to their overall numbers in the US population.

In fact, in 2019, although African-Americans made up less than 14% of the population (according to official census figures), they accounted for more than 23% of the just over 1,000 fatal shootings by the police.

And that figure has been relatively consistent since 2017, whereas the number of white victims has come down since then.
