There is something about the way the CIA has been functioning that is casting a shadow over our historic position and I feel that we need to correct it." President Harry S. Truman wrote those words in an op-ed for the Washington Post on Dec. 22, 1963. This was exactly one month after the assassination of President John F. Kennedy and a bit more than 10 years before the ... Church Committee [formed] to study abuses in the intelligence committee. Sadly, we seem to slip back into the same old patterns where ... the CIA goes off in secret to "do its thing." Whether it was overthrowing governments beginning in the 1950s, the attempted assassination of Fidel Castro ... or creating secret prisons for torture in the 2000s, the pattern is truly disturbing; in some cases, it was so disturbing that the CIA conducted internal reviews of its own actions. After the Church Committee investigation in 1975, our intelligence agencies were prohibited from assassinating foreign leaders and illegally spying on Americans, and the Foreign Intelligence Surveillance Court was created to further ensure prevention of unreasonable searches and seizures. In addition, permanent congressional oversight committees were established to do just what Sen. Dianne Feinstein's, D-Calif., committee did last year to investigate the CIA on torture. It is ... doubtful that we will be holding the perpetrators accountable. We need a new Church Committee or serious presidential commission, [because] the new world in which we live ... demands far greater oversight.
