I actually agree in principle with some of the what the OP argues in as much as it not that reasonable to place the blame for every single act of child abuse with the WTS and that there are difficult moral and legal issues around some specific scenarios, especially where local laws are concerned.
The fundamental issue however is that the WTS has supplanted their self proclaimed pastoral role with that of a legalistically based culture of self-preservation. Over and over again victims have been let down by an organisation intent on covering it's own arse. Corporate and individual conscience and moral strength is trumped by the need to minimise any risks to the organisation. This is bad enough in itself but this corporate requirement is then wrapped up in the highly emotive clothing of "protecting Jehovah's name", further reducing the likelihood that individuals on the ground will follow their heart or question the instructions they are being giving.
It's all about loyalty to the organisation rather then to the victim. Their rights, needs and health are at best third place behind the organisation and the alleged abuser.
The WTS has suppressed critical thinking abilities so much that the organisation is plagued by a lack of skills in being able to weigh up difficult situations and make a call. They have no debating skills. They have a lack of logical processing. Individual cognative dissonance has escalated to an organisational level. They can only think in black and white terms which is why they resort to pouring over what their legal responsibilities are, using the law as a benchmark for right and wrong.
In so doing they completely miss the point of the law and their responsibility as pastoral carers to make choices beyond the letter of the law.
Apologists can whine all they like about the over emphasis of blame on the WTS and the conundrums it has to face with this very difficult situations but the WTS is not unique. These issues have not stopped other organisations from learning, improving and taking genuine steps to improve their handling of events yet the WTS seems intent on reverting to type and simply making things yet more legalistic and stepping away from any sort of intelligent thinking on the matter.
