This subject has been brought up before. The Governing Body and Watchtower have repeatedly encouraged JWs to show loyalty to the organization to "keep the Congregation clean" by reporting wrongdoing to the elders.
I know directly of two cases. Two JWs working in the records department of our local hospital "outed" 3rd Gens 1st husband to the local elders when he and his mistress sought medical treatment together for stds. -She was happy to find out, and both sisters kept their jobs. Hubby #1 got disfellowshiped and she got a divorce.
The 2cd was a case of a JW working in medical records of a famous SF Bay area teaching hospital who turned in a young JW girl for an abortion. She was outed to my body of elders and disfellowshiped.
I heard many other cases of inside information and records being shared by JWs with inside information at many types of offices when I worked at Bethel.
Has anyone heard of more recent cases of "leakers"?
