I've seen several bloggers recommend this article in The Nation by Chris Hayes and I'm going to join them. It's partly a brief history of the Select Committee to Study Governmental Operations With Respect to Intelligence Activities which was created in 1975 and is more colloquially known as the Church Committee. Led by Senator Frank Church of Idaho, the committee conducted a wide-ranging investigation of abuses committed by the American intelligence apparatus, from the CIA's attempts to assassinate Fidel Castro (among other international figures) to the FBI's spying on American citizens, including attempts to blackmail Martin Luther King into committing suicide. The work of the committee is widely credited with inspiring reforms to improve oversight on those agencies and one of the hallmarks of the Bush administration was its attempts to either roll back or circumvent that oversight.
Hayes also tries to build a case for a modern day Church Committee:
Public debates over intelligence are qualitatively different from other policy discussions. In a debate over whether, say, the economic stimulus has been effective, there is a presumption that all participants are working from a common set of data--GDP growth, unemployment, government spending, etc.--but with different interpretations and emphases. Such is not the case when the issue is the effectiveness of intelligence programs or the scope of covert activities. Those debates are conducted on fundamentally unequal footing. Critics may charge that torture is counterproductive and produces bad intelligence, but defenders of the secret government can wave away such concerns by saying, more or less, You don't know what we know.
What the Church Committee did was to eliminate this inequality by wrenching an entire segment of the state into the light of day. It created a universally accepted set of facts, a canonical public record that turned the secret conversations of the powerful and initiated into the material for a broad debate. It brought the world of intelligence into the public sphere, the place where self-governance ought to take place.
The first paragraph of that quote put me in mind of statements by CSIS that tell us all about the terrible things they've prevented without telling us anything at all about the terrible things they've prevented. National security, you know.
The title of this post, by the way, is a quote from Richard Clarke who is best known for serving as a counter-terrorism advisor to both the Clinton and Bush 43 administrations. On his retirement in 2003 he became a vocal critic of Bush's War on Terror™. He agrees with Hayes on the merits of a thorough investigation.
If any of this is of interest, read the whole thing.
