Having been betrayed by someone close to me it is absurd to imagine that you can have absolute certainty over the probity of a public figure you barely know. That is especially true when those people are involved in the "dark arts" or the manipulations of politics and media. Who is a double vs triple agent? Who is being exposed vs doing the exposing? Who has a latent weakness for power that is activated? Even in retrospect it can be hard to figure out who the real valiant vs villains are. It's OK (and necessary) to have an opinion over which sources to trust, but that always has to be tentative.
