The "clergy-penitent" was used out here in CA for two cases I know of. The brother that murdered his wife, Kelle Jarka, and another guy who confessed to molesting various young girls. It didn't fly in the courts here either. Specifically because it is not kept discreet between the confessor and clergyman. It's reported to HQ and is reviewed with other BOE's and traveling overseers. There is no confidentiality to warrant that exclusivity intended for the confessional.
I hope the hits just keep coming.
