Back in the day one of my friends was sent to school to be lawyer by the WTBTS. He wasn't even a Bethelite, just a pioneer. While he was going to school they had him work as a caretaker at the Jersey City assembly hall.
He told me there were 4 other brothers who they did the same thing with. When I asked him why they chose him, he said the c.o. selected him because the society asked them to find studious brothers that they felt were qualified.
On a side note he is one of the main lawyers on the child abuse case.
