The purpose of the HLC has always been confusing to me.
The elders I knew that were on it were some of the most pretentious wanna-be's. The JW's are all about image and public perception but they have managed to find a way, via the HLC to piss off well meaning medical staff and non-witness families with threats of legal action concerning how a JW patient is treated.
It is a great example of how much power and control the organisation has on its members. They have to be involved in the most vulnerable parts of their life.
