The system works well if the Elders can respect the privacy of the congregation.
In our congregation, I was the secretary, and only I and the PO had the keys to the congregation files. The Judicial Committee files however were in a a metal file box that had a separate lock(the PO and I had the keys for this box}. Not all the Elders in the body knew of the details of the files in that box, but they did know about the charges for the congregation member.
We had good body that respected the privacy of such matters, but I do recall two elders that would reveal details to their spouses. They were removed for doing so.
Something disturbed me when I was pioneering in the early 70's. I was talking to a person whose sister was married to an Elder in a congregation in the East of Canada. I asked this person if she had any news about a brother who I had met back then. She was apparently visiting her sister down East, and what she told me was details that could of only been given in a judicial committe. This person giving the info wasn't even in the organization. There was a definite breach of confidentiality there.
I do see the need for talking and confiding our problems to a Mature individuals, but it will backfire if that person can't respect your confidence. You may be better off talking to a Schrink who is under law to maintain your confidence.
