You would think that this would mean that forevermore we could bring this up to any normie repeating something they'd heard in the MSM as if it were rock-solid fact and say, "Remember that time NBC said intelligence agencies plant lies in the media? How do we know this isn't another one?"

Of course, it doesn't mean that. They'll just say, "Yeah, well, this is true. What are you, some kind of conspiracy theorist?"
