Vinny, all due respect, you must have been a hell of a witness: dogmatic, opinionated and condescending. And you ain't got over it, no matter what you think.
Regarding what Snakes wrote and you quoted, NO, a secretary's 'natural' reaction won't be calling Patterson. Your average secretary will not call Patterson to confirm an address or a phone as a regular procedure. They may call to get such information if they don't have it; but if they have a name, an address and a phone number, they will not double check with the offices (why would they?). Some may do it, but they are not mandated to do so, and most I know will just try to get in contact with original committee over the phone (WT warns against Mobiles and wireless, but using landlines is perfectly OK, and contrary to what was stated it does not violate WT protocol).
That being said, I agree the 'fake congregation' plot has many holes and there's a good chance it would get caught.
As for the motivation, I agree that it seems a bit pathetic so much effort to be in good standing within an organization you hate. But, on the other hand, I can relate to the pain that being shunned causes; there's no limits to what one would do for parents and children and loved ones.
So no judging here. I would not be surprised to it works, I would not be surprised to see it fail. I've seen weirder things happen.
