"JW elders are not covered by clergy penitent privilege."
WHY NOT?
A "penitent" is a person who is repents the wrongs they have done. Additionally, Clergy-penitent privilege, also known as priest-penitent privilege, is an evidentiary rule that protects confidential communications between a member of the clergy and a person seeking spiritual counseling from being disclosed in court or other legal proceedings.
Notice that it requires "a" member of the clergy, not three gossips. So if I tell the triumvirate about my murders, that is not a clergy-penitent confession, it's a chat with "the guys," or, as Anony Mous put it, a "business meeting."
Let's say I go to a Judicial Committee of three elders and tell them that I was mugged. I have not committed any wrong; I am not "confessing" anything.
