Here I go again:
You could have the Governing Body sodomize young boys on a parade float being towed down Broadway at high noon and Joe Witness would just say, "It's still the truth".
I'll go one further: You could have a flying saucer land next to the UN and proclaim that they've been guiding us for centuries. Next day, congregations would remind publishers to turn in their time and what the offer for the next month is.
That said, there is only one way I know of to precipitate a sudden collapse of the organization. It is the same 'only reason' that can cause a congregation to suddenly fold up (apart from publishers moving away). You need an open struggle at the top, the leadership.
This cult needs blind obedience to leaders - and if the leaders are in open warfare, that's when things fall apart. The Governing Body pretty much knows this, as a principle.
