I can believe the CIA has all sorts of assets in obscure places. Believing the CIA is directing its assets to have sex with a target then wait several days until a chance conversation with somebody else about his alleged sexual indiscretions before making a crime report so tentative the case was only reopened on appeal is a step much further. If the CIA wanted to honeytrap someone, which certainly wasn't the most obvious route to going after Assange, they'd have made the case stick.

Similarly, believing that everybody who has ever interacted with an anti-Castro organization (the only "evidence" presented of CIA involvement) is a CIA asset is a step beyond which I'm willing to go.
