Just goes to show you how good they are at staying underground. Like you said, the fratto case proved that Cleveland is still heavily active as well. A lot of it is also due to the younger generation not having records. Also, the way Aiuppa set things up with each crew being its own miniature family, there is less communication between crews than ever before, so its difficult to discern what is happening within each crew, as no one answers to a "top boss" anymore.

I'm working on a thorough response to the questions posed by you & PP in the rudy fratto thread, its just taken me a while, I apologize. I will try my best to explain the difference between prime outfit (Ricca/giancana) and modern outfit structure, as implemented by Obrien, Carlisi, & DiFronzo.
