I hereby profess my love for the Government Accountability Office, known until 2004 as the General Accounting Office.
From Wikipedia:
The Government Accountability Office (GAO) is the audit, evaluation, and investigative arm of the United States Congress. It is located in the Legislative branch of the United States Government.
The GAO was established as the General Accounting Office by the Budget and Accounting Act of 1921 (Pub.L. 67-13, 42 Stat. 20, June 10, 1921). This Act required the head of GAO to "investigate, at the seat of government or elsewhere, all matters relating to the receipt, disbursement, and application of public funds, and shall make to the President...and to Congress...reports (and) recommendations looking to greater economy or efficiency in public expenditures" (Sec. 312(a), 42 Stat. 25). According to GAO's current mission statement, the agency exists to support the Congress in meeting its Constitutional responsibilities and to help improve the performance and ensure the accountability of the federal government for the benefit of the American people. The name was changed in 2004 to better reflect the mission of the office.[1]
The GAO is headed by the Comptroller General of the United States, a professional and non-partisan position in the U.S. Government. The Comptroller General is appointed by the President, by and with the advice and consent of the Senate, for a 15-year, non-renewable term. The President selects a nominee from a list of at least three individuals recommended by an 8 member bi-partisan, bicameral commission of congressional leaders. The Comptroller General may not be removed by the President, but only by Congress through impeachment or joint resolution for specific reasons. Since 1921, there have been only 7 Comptrollers General, and no formal attempt has ever been made to remove a Comptroller General. The long tenure of the Comptroller General and the manner of appointment and removal gives GAO a continuity of leadership and independence that is rare within government.

The GAO is probably the only example of a prominent U.S. government office or department that hasn't been visibly under the Bush 43 administration's thumb. The GAO has released report after report detailing the reasons many in the administration should be imprisoned, or at the very least humiliated and run out of the country. In reality I'm thankful that we're not one of those nations where there's a coup every time it becomes obvious the government isn't acting in the interests of the people (or is breaking national and international laws); I think stability is key in a nation of 300 million people with the largest and most powerful government in the world. But if the criminals in our government were put on trial, would the "activist" judges dare to find them guilty? If they were imprisoned, would it send a clear-enough message to leaders of future generations that executive privilege does not mean they can break any laws they want and suffer no consequences?
