Referring to the press release mentioned at http://www.jehovahs-witness.com/6/112393/1.ashx, it should be noted that WT is a corporation, with attorneys looking to cover themselves and their employer. It is noteworthy then to consider what WT defines as a 'known child molester' as it is one classified as such who cannot hold a responsible position in the congregation.
Letter to Elders March 14, 1997: "Who is a known child molester? The January 1, 1997, Watchtower article "Let Us Abhor What Is Wicked" mentions on page 29 that a man "known to have been a child molester" would not qualify for privileges in the congregation. An individual "known" to be a former child molester has reference to the perception of that one in the community and in the Christian congregation. In the eyes of the congregation, a man known to have been a child molester is not "free from accusation" and "irreprehensible," nor does he have "a fine testimony from those on the outside." (1 Tim. 3:1-7, 10; 5:22; Titus 1:7) In view of his past, people in the community would not respect him, and the brothers might even stumble over his appointment."
With regard to dealing with the media, at the 2005 Kingdom Ministry School, elders were given a statement to be read verbatim to any inquiring reporters:
"The spiritual and physical welfare of Jehovah's Witnesses is of paramount concern to the elders who have been appointed to shepherd the flock. The elders extend this shepherding confidentially. Confidential shepherding makes it easier for those who seek the elders help to do so without worrying that what they say will be divulged later. Consequently, we do not comment on whether elders either currently or previously met to assist any member of the congregation."
So what all this means is that if a victim comes forward, and no one else knows about it, it is possible for an accused individual NOT to be considered "known." It is the public knowledge and the knowledge of the congregation at large (not just the elders) that determines whether this person is barred from office. That leaves a lot of wiggle room for confidentiality and congregation switching to protect a child molester.
