Legal system was set up for plunder and to protect the plunderer, if you read up any of the early US legal practices , it was mostly bought for judges and courts that helped forge most of what you now know as old money. After the plunder phase legal system moved to protect that plunder, the legal system always evolves with the needs of the elites.At present its required to prosecute political opponents and it will do that easily and willingly.
FBI should have been broken down never to see light again after Hoover experience . But now days Political swamp creatures fear the 3 letter agencies not the other way around.
