> widely documented disparities in how US law-enforcement agencies treat people of different races and ethnicities
Citation needed, particularly for Nature. As far as I can tell the supposed disparities are explained by the amount of violent crime the race and ethnicity commits (leading to more police interactions), but it's impolite to bring that up.

Would you also like a citation for the statement "racism exists"? There are some truths that are so plainly obvious and supported by mountains of data that it's absurd to demand a citation for them.
