While not having the time to pick up this discussion right now, just a small correction: You stated that "a busload of Witnesses burnt to death in Spain on the way to the District convention (some years back)."
Actually, they were not on their way to a convention, but they had been out on a Saturday or Sunday trip, some friends together; while this does not alter the terrible tragedy thathappened, many people frying to death being caught in the burning bus, then it was, as I said, not in any way connected with a convention.
