I remember reading somewhere about 19 made men originally from Sicily getting hanged by the local population in New Orleans sometime in the 1800's for trying to extort local businesses. The bosses back in Sicily realized they couldn't fuck with the local population there and limited their extortion rackets to Italians only.

You would have thought there would have been massive retaliation for so many made guys killed but the Sicilian bosses, showing their shrewdness, ordered the reminding made guys to stay low and that is what they did for 10-15 years before they started to come into their element and form what we now know as the New Orleans family.
