I understand what you mean OrderLimit. I know it's extreme but I'm trying to cover all possible scenarios. I can imagine many skeletons come out of the closet when a person is arrested and/or charged. I trying to understand about fairness and unfairness of evidence, the difference between hard evidence and tittle-tattle.
In the last scenario, I was assuming that it would be the therapists duty on hearing about Person A's arrest to inform the police/courts, otherwise, how would investigators know that this possible evidence existed if they didn't know he was seeing a therapist.
I understand that fishing for evidence is illegal and must not be submitted if proven the evidence was gathered illegally.
