Old Man Thoburn sold the first property owned by Fairfax Christian School to the Saudis and got big bucks. Then he and his family got into trouble with the IRS over the sheltering of money from the sale of a for-profit property.
Anyway, once the Saudis got the property on Popes Head Road, they turned it into a walled compound. For all we know, OBL is hiding in there.
