Final answer:
Italian organized crime known as 'Cosa Nostra' OC is a type of transnational organized crime originating from the Sicilian Mafia, requiring international cooperation to combat its wide-reaching illegal activities.
Step-by-step explanation:
Italian organized crime is often referred to as Cosa Nostra OC. This term is closely associated with the Sicilian Mafia, which is a renowned example of a transnational organized crime (TOC) group that engages in criminal activities that cross state borders. Such organizations are notorious for employing violence and corruption to benefit from illegal activities. The Sicilian Mafia is known for its stable and definable membership, in contrast to other criminal groups that may have more loose and flexible structures.
Transnational organized crime is a significant threat to international peace and security. It represents a global governance problem, requiring coordinated international efforts from domestic criminal justice organizations and international governing bodies like the United Nations Office on Drug and Crime. Criminal activities during the Prohibition Era, like those of Al Capone, exemplify the rise of organized crime syndicates that operate across borders.
