Interesting story mathilde, I hope your boys did not suffer any harm. I have a similar story. In my old hall, one of the highly respected elders began studying with a young boy in the congo, who was fatherless. This young bro (young teen) went to the elders to tell them how this elder would take his penis out and ask him to touch it, and would also try to touch his penis. Nobody believed this kid, there wasn't even a JC over the issue, the rest of the elders just blew this kid off. Pretty much everyone in the congo knew the story, but this boy had no status at all, and only a mom to speak up for him, so everyone just ignored him.
Fast forward a few years later, this elder is arrested for soliciting a minor in a public place. The cops came to his house but he barricaded himself in and waved an inoperative gun in the attempt to get the cops to shoot him. Fortunately the cops were able to collect him with no one getting hurt. I understand he is now a registered sex offender.
Another story, a young girl in our hall is under the guardianship of her uncle, who the elders know is molesting her. he molested her two older sisters, and as soon as they were old enough they left home and moved in with boyfriends. The elders were trying to "save" this last girl. They didn't want to report the abuse because then the girl would be put into foster care and possibly not be allowed to attend meetings. So they were "working" with uncle to get him to stop. How do I know all the details? I heard it first hand from the elders wife who was studing with the girl. She invited me along one day and told me the situation on the drive over. That whole hour I could not take my eyes off this poor girl, and I could not stop the cognitive disonance in my head. I am ashamed to say I did nothing to help her either, I just told her she had pretty hair.
I know an elder in southern california who is serving on an elder body that includes a man that raped him as a boy. They grew up together only brother rapists is about 6 years older. Now they serve the congregation together.
My stepdad is a molester too. He has always remained in good standing with the congo, because if there isn't two witnesses, "it didn't happen, you must forgive, and you must never speak about it to anyone".
