The White House or DOJ is behind most if not all of these prosecutions. Having a black or foreign (or both) prosecutor means that anyone who criticizes the obvious illegalities in the cases can be attacked as a racist.
Its also calculated to plant ideas in black voter’s heads because they may be more likely to actually listen to and agree with a black prosecutor’s argument simply because racism: the person talking is the same race as the listener
Yet our stupid spineless POS assholes in Congress gave the FBI CIA and the DOJ power to spy and jail conservative citizens by passing FISA. Hate them!!!
