In principle I don't actually completely disagree with the instruction to call Bethel Legal in as much as there are potentially legal obligations and implications for the elders that they may not be aware of, especially in a country where local (e.g. state) laws and agencies may differ. The problem is that the WTS has a cultural deficiency in being able to understand what is the moral and ethical right course of action compared to what their legal obligations are. They would rather the government tell them what to do than even consider changing their policies to reflect the best practice being implemented by many other organisations.
This is a cultural meme that replicates itself through the hierarchy. It is why elders, some of whom are intelligent and thoughtful people, cannot find it in themselves to follow their conscience and take action even when not explicitly forbidden by their superiors at Bethel. It is why relatives of victims cannot take action as their deference to WTS culture overrides their own moral judgement. It's why loyal congregation members support the organisation and it's policies without ever questioning or considering that morals, ethics and conscience can override whatever the legal obligations of a organisation or individual may be.
