These two and the third one who signed the report. And everyone who’s already not taking actions (for eg their superiors). If law enforcement’a job is not uphold the law then what is it? Why haven’t they already arrested the two and filed a complaint themselves (the County Sheriffs) what’s stopping them?
Too lazy to search, but within the last year I remember a series of podcasts exploring systemic racism from a vaguely reputable source (sorry) that at one point cited a (supreme?) court case where it was established that law enforcement actually has no obligation to "serve and protect", and all other expectations that don't follow from that.
If you think it's just these two people (especially when a superior officer signed off on it), you have a lot to learn about the way policing works in this country.
