I think a lot of rumors and conspiracy theories about the FBI, CIA, NSA, and other such agencies stem from perceptions that they are super-secretive and that their motives are not related to genuine matters of national security (which is generally reflected in US policies which are known to the public).
In other words, if a politician or other official states a motive which can not be justified by a legitimate national security need, then that's generally a clue that something foul is afoot.
To point out an obvious example, anyone who could read a map and discern the distance between Vietnam and the United States could easily tell that any tales about a communist insurgency in that far-away country threatening US national security were fabricated nonsense. When the government is caught in a blatant lie like that, then it creates a palpable atmosphere of distrust between the government and the people.

To punish him for disclosing the truth about the squalid things that woman did.
The truth is: who is the bad guy here? Hillary or Assange?
