"Structural/systemic/institutional racism" are just fancy terms used to describe disparate impact, which piggy backs off the vitriol of intentional racism to give the impression that they are the same. They are not.
With that in mind, if you think there is not "systemic racism" in our police, you are wrong. Where things get off track is the belief that because there is a disparate impact the police deserve to be treated like "racists," in the classic sense of the term.
