I just sent this:
Hello,
I understand you are currently considering which institutions to investigate as case studies in your inquiry. I would like to recommend that you include Jehovah's Witnesses as one of your case studies, as they have consistently refused to make improvements to their child protection policies (believing as they do, that their archaic and inflexible interpretation of the Bible is superior to "worldly" best practice).
You are no doubt aware that the JWs were included as a case study in the Australian Royal Commission, which exposed the severity of the situation (their policies and practices are pretty much identical in every country in which they operate).
Thank you for considering this request, and I send my best wishes and support for your work over the coming years. I am hopeful that it will have a positive impact on the lives of many children.
