Andriacchi rose to the top levels without a sniff. So did Al Tornabene, the pizza man although he's recently deceased.
I don't think either did any real time, maybe some petty shit when they were young.
And honestly DiFronzo didn't do a lot of time, especially when you consider his position the past 20+ years.
Hard to believe in this day and age.
Andriacchi did some time in the fifties on a burglary rap, if I remember correctly. He was convicted along with Pete DiFronzo and Lee Magnafichi.
