Again its important to stress that the WTS. perceives pedophilia in the same genre as other sex related sins such as adultery or fornication
That is the key to understanding the WTS reaction to all of this.
In the WTS collective mind, child rape is no better and no worse than 2 unmarried adults engaging in consensual sex. To them it is all merely "porneia".
Just as they think it is important to "protect the privacy" of the 2 consenting adults, they think it is important to "protect the privacy" of the child abuser as well.
Of course, they really don't give 2 figs about "protecting the privacy" of anyone. They are principally concerned with protecting the assets and reputation of the organization, and yes, in that order.
