Hard to argue with the highest of Internet law but this is literally a paraphrase of President Truman's description of the FBI, found in the third paragraph of J. Edgar Hoover's Wikipedia page no less [1].
But do go on, trot out some stupid internet meme while the American government continued it's descent into the abyss.
This is tin foil hat circular reasoning but given the historical evidence for Hoover's abuse of power, I don't think it's much of a stretch
