NASA will eventually admit the Moon Landings were fake by simply saying, "Oh, yea, they were fake as hell. EVERYBODY knew that. We fooled the Soviets for a while, which was the whole point, but the average American wasn't fooled for a second, except for a few idiots."
Who will admit to being one of the "idiots?"
So, instead of holding these NASA liars and thieves to account, the public will simply agree that "they always knew it was fake."
