"It's a self induced belief. Just like the other poster saying that Salvatore Maranzano was the one and only Boss of Bossses. Also, he doesn't have proof that Maranzano was the one and only in that position. The older mob history is more hazy then todays, so who really knows what happened."

DeMeo, nobody here said that Maranzano was the one and only boss of bosses. But he was the last one.
And actually, there are a lot of accounts of what happened during the early history of the mob. I´m sure you have heard about Joe Valachi, right? Nicolo Gentile? Joe Bonanno? Mike Dash? David Critchley? John Dickie? The FBI???
