HL,
I don't think there is any way around the fact that no matter where the money comes from (i.e., which specific asset of the Borg's) the bottom line is that everything the Borg has is sustained by the contributions of the R&F. Even if the argument is made that the source is their investments, the ultmate source of the money used to make the investments comes from the R&F.
They are a morally corrupt, deceitful, dishonest, and just down right slimy.
From the looks of things, they are probably using money from the sale of the Brooklyn properties, to stay liquid.
The whole pedophile scandal reeks of coverup, damage control, and shielding the average Dub from as much information as possible. Unless someone on the inside leaks the information to those on the outside, we may never know.
Sorry, I know this isn't much help, but it is my take on things.
