I could be wrong as I have little experience with the category, but I am under the impression that they are expected to maintain confidentiality with their clients, in a similar way to lawyers, doctors, priests and psychotherapists.
So if A hires Mr. Bogart to spy on B, and then C comes to Mr. Bogart and tells him “I’m interested in B, and a little bird told me you spied on B for someone”, basic professional ethics would require Bogart to refuse to discuss anything related to A’s case with a random stranger, potentially costing him his licence should he fail to do so (depending on what regulations apply in Bogart’s country).
Well, to be pedantic, doesn’t that then include your example above of private eyes?
