> The DOJ took it up, but at one level it would be obscene if they didn't - imagine the inverse (some evidence of anti-black admissions procedures is found), and the DOJ - who is tasked with prosecuting hate crimes and other civil rights-style issues - did not take it up.
You mean like publicly abandoning ongoing investigations of systematic racial discrimination by local police departments while dismissing the entire idea of conducting such investigations when there was evidence in hand as an intrusion on law enforcement?
The DOJ did that almost immediately when the current Administration took over.
> this sort of topic is the DOJ's bread and butter, and since it began via lawsuits from the affected parties I don't think there's much cynical "discretion" going on in this particular case.
The DOJ doesn't join or follow every, or even most, discrimination cases filed by private parties which are minimally viable and state claims which would also provide a public cause of action, so I have no idea on what basis you jump from “started by a private lawsuit” to “therefore doesn’t have much cynical discretion involved”.
