I recieved just that book you mentioned, i am going to read it
and yesterday i finished reading Gangbusters, its a good book but the author acts like the mafia is dead and is more like a street gang with low life criminals. I dont agree with that, they are still active with scams involving millions of dollars. And he describes Gaetano Lucchese as one of the best dons of OC. Oh not to forget Ducks Corallo, they were smart yes but not the way he describes them.

Yes there are exceptions, like the killing of Fat Pete Chiodo's sister if i remember correctly with order of Casso. And a couple in the Colombo wars, the american mob also has a rule right? not to kill infront of his wife or children. But that rule was also broken several times, most notably in the Colombo Wars.
