I actually said that I must sound like a shill, meaning to conspiracist kooks who have already decided that everything the government says is a lie.
Pretty much every lie the NSA has told has been a proven lie a few days later after an expose/new release of documents. That isn't a conspiracy, it's a fact. And while not a fact per se, it's certainly an arguably correct view at this point to believe that whatever the NSA claims on any given day is 180-degrees of the actual truth.
P.S. Some conspiracy theories, such as Tuskegee syphilis experiments, COINTELPRO, Nicaragua death squads trained by the US, etc., are true. "Conspiracy Theory" does not 1:1 equate to "false". It's like "UFO". Well, Unidentified Flying Objects can indeed by unidentified even by no one who believes in aliens. Once identified, they are no longer Unidentified. Once legitimate conspiracies are identified, conspiracies are no longer theoretical, they're factual. Once mammals in Vietnam are discovered by biologists, they are no more "crytozoological" species purported by Vietnamese folks; they are factual specimens.
...once (or dozens of times) NSA spokespeople lie, then it isn't a "conspiracy" to think they'll continue to lie. It's both born of past facts, pragmatically a wise supposition, and also is indeed a conspiracy by the NSA spokespeople and at least one other (definition of conspiracy btw) in the administration (who did not immediately prosecute him for lying to Congress).
It's sad that 9/11 and Holocaust and JFK head-shot and whatever have made "conspiracy" into a bad word describing the impossible. Conspiracies do happen, and exist, and your government is engaged in it right now, Joey.
