They are hierarchial, yes, Amazing, which means governed top-down. And normally that would automatically lead to their having to pay out from the national organization's single business account.
However they split into different corporations in the U.S, so that the account is also in effect now divided. If a victim sues an elder who molested her and wins, then the assets are according to the new paper trail to come from the new corporation called the Christian Congregation of JWs which deals with personell such as elders, CO's, DO's.
Well, there isn't much money or many nontangible assets with that particular congregation, as they well know. Instead they mostly their assets into the other new corporations such as the one mostly for printing equipment and the like.
This may not keep the victim from getting access to the other corporation's assets, but makes it more difficult. She would have to go through another legal maze to prove that this other corporation is liable even though it is "now" structured as separate from the corporation for personnell.
As to pedophilia being more prominent in some U.S. regions more than in others, yes, I believe that's quite possibly true. At least among the recent spate of Catholic scandals there appears to be a lot more such instances in California, Missouri and several small East Coast states such as New Jersey. I saw a map of the U.S. and dots in the states where the cases were.
I doubt though that the WTS misleadership (Gov Body members led by their attorneys) would try to restructure regionally or they would already have done so. In effect they re-did their house already then said "ha, ha, ha, now come and get our assets!"
Well, it can be done, but they have built extra legal walls around their pile of blood-soaked money. This California law could be very helpful though especially for getting local elders as individuals to pay out for the hiding of crimes. That or go to prison. Ditto the RICO law for federal racketeering.
