The clause in the exemption is why it's not a general exemption. It specifies under which terms the state of Delaware recognises a clergy exemption to report. Eventually Fisherman will catch onto that. It may not be intentional, it may just be clumsy phrasing, but it puts WBTS into the awful position of reporting their child abusers in Delaware to the authorities and making sure children are protected from harm. What a wicked law.

@Joe - interesting that from your perspective at the frontline, thank you. The legal background may interest you. It's a little obscure and case law dating back centuries... the ultimate endpoint in Britain is for a judge to rule that something is required for the public interest. Once that ruling is made, you can end up with Catholic priests in the dock expected to testify. (Although last properly tested back in late Victorian era!). CofE clergy are still in an odd place with the whole confession thing - legally obliged to remain silent (state church legacy) but also equally subject to a judge demanding testimony. Last I heard, they were trying to figure out how to fix that themselves.
Judges don't tend to press that hard though (the discretion under PACE) which is why it's only when dim JWs try to muck up major child abuse investigations that the stick comes out. Like it did in Newcastle not so long back. And then after months of the judge trying to persuade them to testify of their own accord. They chose to testify on the morning of the trial, rather than spend some time at Her Majesty's pleasure.
