Heard a couple of interesting things tonight from my folks, who were discussing this with an old cop friend.
First, the tip-of-the-iceberg theme revisited; he claims that we haven't heard 90% of the dirt because of the need to protect informants. However, the case is still very much ongoing and Lisi rolling over is taken as a given.
Second, he says that RoFo actually owns a couple of these crack houses through a numbered corporation, and all the money is in the US.
Third, Rob is a serious drug user but has no actual role in selling or distributing.
I can't personally confirm any of this, of course, but the source is pretty legit. I'm happy to hear any interesting new info.
