Perhaps this is more of a trope, but I'm looking for a phrase or word in English that describes the situation where:
(a) "Party A" consciously performs actions that establish a false expectation of wrongdoing.
(b) Some antagonistic "Party B" leaps to the conclusion of wrongdoing due to [a].
(c) The lack of wrongdoing is revealed by "Party A" to some unbiased "Party C", and "Party A" improves its standing to an unbiased audience or benefits from reducing the perceived objectivity or fairness of "Party B".
Is there some phrase or common anecdotal reference used by English speakers to reference this sort of situation?
An example of this would be the following: Let Party A be Alice, and Party B be Bob. Bob's dog is missing, and because of some bad history, Bob claims to the police that Alice killed his dog. Alice then waits until she knows (but Bob does not) that Bob is observing her, and digs a hole in her backyard, then appears to throw something into the hole. Bob runs to tell the police he saw Alice burying his dog, and the police dig in the location Bob specifies. It turns out that Alice was simply planting tulips. Bob is discredited as being paranoid and Alice gains sympathy. To clarify, it's unknown whether or not Alice actually killed Bob's dog, but she knows that there is suspicion cast on her by Bob's claims.
Another example could be the following: Alice is in fierce competition with Bob at work, and Alice knows that Bob is talking to others to gain information about her activities. So Alice pretends to be stealing Bob's idea for a proposal, mentions this around the office, and then submits a proposal having nothing to do with Bob's idea. Bob, upon hearing the rumors, angrily confronts his superior about this, and is red-faced after being presented with a copy of the report.
What word or phrase describes the deceit Alice carried out as described above, to benefit her standing with the police at Bob's expense?
