50 years have passed since Joe Valachi revealed to the world the existence of La Cosa Nostra. Only I would ask those who are more experienced than me, if the guilt at the end don't was of Genovese.
He wanted the Apalachin meeting, and was always giving him the kiss of death to Joe Valachi believing that he had betrayled him, without having the evidence.
Valachi even if he was a low level soldier of the family, would certainly not spoken, until after he had killed a thief mistaking him for a gunman, he had faced to choose to the risk of be whacked in prison by the Genovese men or to finish on the electric chair.

what is your opinion?

I think if the Genoese hadn't been so eager to become capo dei capi, Apalachin and the betrayal of Valachi wouldn't have happened.
