who the heck is in charge of doj and fbi and why don’t they jump in to see justice done?
The function of those institutions is self-promotion. "Justice" is not a factor in that, other than the usual lyin' lip service, "honorable institution" and such tripe. Prosecutors are measure by convictions. Cops are measured by busts. Regardless of the fact pattern, every one of these is accompanied by a claim of "done good" and "Justice!"
One of the attributes of government institutions is never admit error, never admit wrong. As far as the institutions are concerned, prosecution of Stone, Flynn, Manafort ... that IS justice. Their job is to roll them into court and secure convictions. We have an adversarial legal system, and the government is the adversary. That is "justice" from an institutional perspective.
Your perspective, and mine, those are not relevant in the least. The institutions don't care if you find them morally just. They only demand that you fear them.
Congress will put just enough heat on them to create an impression of oversight and control, but where the rubber meets the road, all the institutions, Congress, Cops and Courts, are in cahoots.
do some research on FBI retaliation. Then do the same for the military. Then do the same for the V.A. Recently the whistleblower PROTECTION department was investigated for doing the opposite.
No one is allowed to talk.
Did you know that the FBI has immunity in other nations and here?
