Mafia protection customers span legal and illegal enterprises alike.

Evidence

The list of the mafia’s documented customers, in both legal and illegal businesses, is long and varied. Landowners, herdsmen, olive and orange growers, peasants, entrepreneurs, politicians, doctors, shopkeepers, purse snatchers, smugglers, drug traffickers, arms dealers: all of them have at one point or another been protected. Some customers enter into one-time-only protection deals with mafiosi, deals which begin and end with a specific transaction. Others, perhaps most, are organically connected to the family, as relatives or friends of the capo and his acolytes, or even as properly initiated members. — Diego Gambetta, The Sicilian Mafia The Business of…, 141
