"Confidentiality", the way a child molester tells the kid not to tell because they will get in trouble.
As has been pointed out often on this board, WWASP and other Programs have demonstrated that they have no problem violating their so-called confidenitality with their inmates.
They use confidentiality as an excuse to hide both their tactics and to keep their prisoners isolated from the outside world. To keep the media out as well.
If you sue your abusers or attempt to have them prosecuted, you better know that they will gleefully use anything you have told them while you were imprisoned against you.
