What the current regime has brought to light is that WAY too much of the American "checks and balances" are based on "trust me bro" and "a person with morals just wouldn't do that". Zero penalties for doing the wrong thing.
People can just go in front of a congressional hearing and ... lie. Just plain faced bold provable lies. Nobody can call them a liar because of The Code, but there's also no penalty for them for lying, zero.
