so the elders should report every accusation (not proven claim) of petty theft, or assault?
You're creating a straw man here.
Anyway my personal opinion is that confessional confidentiality in regular churches is hardly justified. I don't realy care about perps of whatever kind who need to confess to stop feeling guilty. They could just go to the police and deal with whatever they did wrong, cleansing their conscience in the process. So clergy should report confessed crimes to the police imho, but it should be mandatory to report child abuse at least.
As for Jehovah's Witnesses: they don't do confessions. They have no confidentiality. So they should at least report child abuse, especially when the law says they should.
Imho elders and clergy have the same rights and responsibilities as any other citizen. Besides, protecting victims and not perpetrators is the right thing to do.
