Constitutionality of the CIA

[Alexander the Pretty Good]

In the How we trained Al-Queda thread, Gelatinous Cube said,

More often than not, it's a result of Government incompetence coming up with incompetent ideas, as opposed to anything sinister. I believe we would be better off without a CIA to perpetuate these kinds of thing [referring to the troubles and intervention in the Balkans]--the CIA is terrible unconstitutional. As is the FBI, but at least it has proven it's worth.

I've never heard that before. I mean, yeah, the Constitution doesn't say we should have a Central Intelligence Agency, but it also doesn't say we should have an Air Force. Care to explain, Cube?
