Could you be more specific about this? What honor could organized crime have? Even the rumor that the "traditionalist" mafiosi don't kill women and children is a lie. Didn't you say so yourself in the other thread? Even Jack the Ripper or a child molester may think they have honor, but that doesn't mean this warped concept of "honor" has to be respected by law-abiding people.
As for their opposition to drugs in their hometowns, it's pure hypocrisy on their part, because they still sell drugs abroad. Look at Gaetano Badalamenti who was the chairman of the Cupola and the leader of the "traditionalist" part of Cosa Nostra, the one who was an example of an old-style mafioso who is supposed to have "honor". He may have kept the drugs out of some areas he liked, but he still sold them elsewhere. At the end he ended up in jail just for this.
