The WTS didn't do the right thing by this girl with their policy, but the legal system at that time didn't protect her either. If he went to jail for this-convicted, I can't imagine how he would be permitted within spitting distance of that girl. That is messed up as much as anything.
If it comforts you, she wanted to be DF'd-consequences be darned, because she couldn't be there. Had you allowed her to stay in the cong., she would have probably just kept acting out in her pain at the betrayal of those that should have loved her the most.
The right thing to do, asking him to go to another congregation who was fully aware of his past, while allowing her to stay in her own-is not possible in the WTS because of their policy. Kinda messed up.
I am in favor of the apology to her and public exposure in the paper. Not of her, but of the situation altogether.
The bad thing-she is probably one of the JW apologists who troll the internet trying to be a good witness for the org. that hurt them.
