I understand that the situation is upsetting. The parole officer should not be passing along information gained from her job. I am not aware of any law that she would have violated but it is probably a violation of state policy. I am sure you could file a complaint with her supervisor. I do not know if there is any liklihood of anything actually being done to her.
The real question is what benefit is it to your father, or you, to file a report. Talk with your father before taking this any further. He may want to start his parole off on a nice quiet nonconfrontational step. The truth is that there are often actions taken against us where the remedy only makes things worse.
