I used to argue with my old partner Daryl Kunde all the time about that. I asked if he listened to the example given by the speaker at the assembly the week before, it was the one [and maybe many here have heard it] where there was a stazi agent who infiltrated the East German Witnesses. He had worked up to Circuit overseer and was just about to give out all his information when he was struck by lightning. Since the state would go into his apt. and gather all his belongings the Witnesses ran to gather up the information he would naturally have laying around when they got there they found he was a stazi agent and took the information he was about to give the state. I asked Kunde if god directs the installation of people he sees fit to eldership, then god wanted a Stazi agent as an Elder and eventually a CO? All I could get out of Kunta as we called him was "God must have seen something good in that man or he would not have appointed him." I was amazed at how Kunta missed the point or was just plane dodging it because he had not logical argument.
Now after a bit of study on how the Stazi or any intelligence agency works they would not let an agent work for years with no contact, in fact they would be watching all the people that he would have given the names of as soon as he came into contact with them. In retrospect this story was nothing more than a urban legend created by the society or a few brothers that sounded good. Just as the Harold Hill story I just posted on another post, a little research and the story falls apart fast.
