FBI Polygrapher as Interrogator?

[clarencex]

Hello:

I would appreciate any opinions on this situation.

I am assisting a woman who had a difficult experience with an FBI polygraph test.  She was called in to discuss a problem that she had reported.  When she arrived, she was told she "needed " to take a polygraph test.  In her desire to be cooperative, she agreed.  The test was given to her by one of the FBI agents.  After he administered the test, he continued to interrogate her for four hours!  At one point he left the room and returned with the "results" of the "tes"t and reported to her that she had been lying about the facts of her case.  He then continued to interrogate her in an arrogant and abusive manner.  E.g. "I knew you were a liar the moment you came in."

Here is the question that I would like some assistance on, if anyone would care to comment.  (We are aware that she should not have agreed to take the test, but it is too late to change that.)   From my research at this site and elsewhere, it seems that the guidelines for carrying out polygraph "tests" are vague and uncertain. But, is not everything about this scenario wrong:?   Is it not highly irregular and unprofessional for the person who administers the polygraph to then stay and interrogate the witness?
                                                
Thanks for any comment you might have.
