From the personal experience of being harassed by campus police as a The Black CS student, in addition to all the straight racist traffic pullovers, I can affirm that it really really sucks. I can also state that having the first hand accounts of uncles and aunts and parents and grandparents subject to the state sponsored racialized attacks of the US South West North and MidWest that yes, it was a thing, it continues to be a thing. When you’ve heard officers with weapons issue racial insults , you don’t need articles with stats to be convinced.
