Besty, Richard Daniel is actually wrong in his assertionthat "there is no power in Law to breach such a confidence".
From the WIKI article I quoted earlier, about English Law, :
" The only professional privilege granted in English law is for the purposes of obtaining legal advice from professional advisers, so there is no priest-penitent privilege." (Italics mine).
These Elders are not Priests anyway according to the WT, they certainly are not profrssional Legal Advisors, so they have no basis in Law for not disclosing this crime immediately to the Authorities.
As I said before, they should be prosecuted.
