I in no way wrote this column:

Reading this made me wonder about my local Kansas City mob. So I looked into it. 

Kansas City Mafia

Boss: John "Johnny Joe" Sciortino

Underboss: Peter Simone

Estimated membership: around 20

found something else out when I was looking that info up...When the Godfather was released, The KC Mob had it blocked from coming to KC. I found that to be an interesting fact.

I would even go as far as to say that the Outfit leader isn't Difronzo. Normally, the way the secretive Outfit work is to employ a figurehead leader to act as a lightning rod for government attention whilst a 'board of directors' oversee the business; a tradition taken from the times of the 'Leader' Nitti and the real power, Accardo and Humphreys.

Good point Noah.  I never really thought of that.

Yes that is indeed an interesting fact lyshitski.
