Everyone has heard of "The Underworld," criminals who deal drugs, run prostitution, manage illegal gambling and other low level crimes.
There's also an "Overworld."
These are people who carry out crimes on a scale unimaginable to most people. They're the bankers, the weapons makers, the heads of intelligence agencies, high level military people and, of course, politicians.
Kevin Ryan talks about "The Overworld" and how the activities and careers of 19 of these members of "The Overworld" dovetail perfectly with the attack on 9/11.
Theres a long promotional and music break between Parts One and Two.
