Why do you think it's apparent that this case in particular will reaffirm that rich white people "are pretty immune from harsh punishment in the criminal justice system"? I mean I don't argue that the wealthy often escape justice, but why would you think the Theranos case is evidence of that? It's literally at trial right now, which is a very, very bad scenario for Holmes. The vast majority of cases (including ones with a guilty plea) don't go to trial.
