I stopped believing the DC experiences way back in 1968. At the 68 DC they had an older sister from my congo give an experience about her 40 years of active servic. She related how she became a JW in the early 1930s, was active preaching, and how she was blessed, etc. This didn't go over well with the older JWs in our Circuit who knew the sister's real story. Moreover, I conducted the CBS in her home and she had told me a totally different story. The truth is that the sister was contacted by JWs in 1930 or 1931 and took their books. Later she attended a few meetings but didn't do any preaching. None of her children became JWs, in fact her sons served in the military during WWII for which she received a patriotic medal, which she wore proudly during the war. Instead of being a JW, she was really what they used to call "an interested person." She didn't really become an active JW until the mid 1950s. So instead of the 40 faithful years of service that was claimed in the DC experience, it was really less than 15.
Since the sister was honest in relating here life story to individuals in the congo, my guess is that she yielded to pressure from CO to embellish her story. No doubt he appealed to her JW patriotism. Unfortunately I didn't get a chance to ask her why the story she told me was so much different from what she related at the DC.
