Even if the studies show no clear bias (the article mentions some criticism and a forthcoming reassessment of the data based on that) the problem clearly extends all the way down to the most minor of police interactions where it becomes harder and harder to explain away.

I think theres a certain set of people who hear "no statistical proof of bias, and emotional issues arent real issues"... so while I agree with you, I just want to emphasize the huge space of systematic problems that cause the emotional issue.
