What Ricobenes' is saying jibes with the most in the know people I've ever spoken to about the Chicago mob.

The academic/outsiders always peg Accardo as the big mastermind boss, but the people who have street knowledge--and by that I mean basically were related to a member of the mob--say he was really just an overseer and uninolved.

They also are all largely enamored, as seen here, with the psychopath Mooney Giancana.
