In the congregation that I one time used to go to a baptized 12 year girl was molested by one of their ministerial servants, guess what?,, she was disfellowshipped for being molested and only 12 years old at that. This was in the Sunnyvale CA USA congregation 2001.
BTW they have an elder in that congregation that has a bad habit of touching young girls breast at gatherings of the Witnesses this was related to me by an elder that was a friend at the time about 15 years ago, he(the molester,) is still an elder as far as I know.
I can't imagine the psychological harm this must cause to little children and yet the GB want more children to get baptized so they can be disfellowshipped if needs be.
