In a word, Lawyers, and they will be the lawyers that the WTB&S has trained to staff the worldwide legal department is in the last few years.
What happens when any other business gets cash and asset heavy? In a nutshell, the LAWYERS figure out a legal way to sell the assets and line the pockets of themselves and the CEO's and other high ranking corporate officers. The Watchtower is just another corporation.
Back in the 40's, Hayden Covington was the heroic defender of Wtiness freedom in the states. He had a very small staff (if any). Corporate law was a small focus at that time.Legal stuff was a "necessary evil" so to speak. Local Congregations arranged loans and finances on a local basis.
In the last 20 years or so the WT legal staff has grown to meet the challenges of running an international business with complex legal issues. To meet the challenge the Society trained several lawyers from the pool of candidates availible in Bethel homes or other suitable brothers.
The knowlege of things corporate is very limited to the average witness. Most, for example, do not realise that the local kingdom hall is under a perpetual mortgage subject to the control of the WT society. In my opinion, I would not think any one on the GB is totally aware of the day to day corporate and legal wranglings of the legal staff either.
So in my opinion the demise of the Watchtower will come from within. What is to stop the legal minds they have trained and retained in powerful position from screwing the WTB&T society out of their assets?
History has a way of repeating itself. The Societys' first major shake up was executed by a lawyer, the "Honorable" "Judge" Rutherford. Whats to stop the legal staff on board today from gutting the Watchtower's finances and assests from within, and bailing out on a "golden parachute"? This has happened in other corporations, it can happen in the WTB&S.
Final thought-- If the legal department is heineous enough to do what they do to abuse victims in open court do any of us believe the are not evil enough the "steal" the WT right out from under the Rank and File brothers and their senile leaders, The Governing Body?
