In order for a criminal organization to prosper, some degree of support is required from the society in which it lives. Thus, it is often necessary to corrupt some of its respected members, most commonly achieved through bribery, blackmail, and the establishment of symbiotic relationships with legitimate businesses. Judicial and police officers and legislators are especially targeted for control by organized crime via bribes.
Organized crime most typically flourishes when a central government and civil society is disorganized, weak, absent or untrusted. This may occur in a society facing periods of political, economic or social turmoil or transition, such as a change of government or a period of rapid economic development, particularly if the society lacks strong and established institutions and the rule of law. The collapse of the Soviet Union and the Revolutions of 1989 in Eastern Europe that saw the downfall of the Communist Bloc and establishment of new systems of democracy and free market capitalism in the region created a breeding ground for organized criminal organizations. Most of the countries fell upon economic turmoil with their markets being flooded with western products that had previously been barred by the communists regimes at exceptionally high prices and a lack of interest in importing from Eastern Europe. This led to many turning to illegitimate means of making a profit, most of the time these efforts were backed by former secret service and police force who were now out of the job.
Under these circumstances, criminal organizations can operate with less fear of interference from law enforcement and may serve to provide their "customers" with a semblance of order and predictability that would otherwise be unavailable. For similar reasons, organized crime also often takes root in many countries among ethnic minority communities or other socially marginalized groups whose members may not trust local governments or their agents. This lack of trust serves both to insulate the criminal organization from the risk that law enforcement will find cooperative witnesses, as well as to encourage community members to trust the criminal organizations rather than the police to handle disputes and protect the community. The existence of a black market, either due to market failure or to legal impediments, also tends to promote the formation of criminal organizations as well. An example of this would be the rise in organized crime under Prohibition in the United States during the 1920s (see American gangsters during the 1920s).
Lacking much of the paperwork common to legitimate organizations, criminal organizations can usually evolve and reorganize much more quickly when the need arises.They are quick to capitalize on newly-opened markets, and quick to rebuild themselves under another guise when caught by authorities.
This is especially true of organized groups that engage in human trafficking
The newest growth sectors for organized crime are identity theft and online extortion. These activities are troubling because they discourage consumers from using the Internet for e-commerce. E-commerce was supposed to level the playing ground between small and large businesses, but the growth of online organized crime is leading to the opposite effect; large businesses are able to afford more bandwidth (to resist denial-of-service attacks) and superior security Furthermore, organized crime using the Internet is much harder to trace down for the police (even though they increasingly deploy cybercops) since most police forces and law enforcement agencies operate within a local or national jurisdiction while the Internet makes it easier for criminal organizations to operate across such boundaries without detection.
In the past criminal organizations have naturally limited themselves by their need to expand. This has put them in competition with each other. This competition, often leading to violence, uses valuable resources such as manpower (either killed or sent to prison), equipment and finances. In the United States, the Irish Mob boss of the Winter Hill Gang (in the 1980s) turned informant for the Federal Bureau of Investigation (FBI). He used this position to eliminate competition and consolidate power within the city of Boston which led to the imprisonment of several senior organized crime figures including Gennaro "Jerry" Anguilo underboss of the Patriarca crime family. Infighting sometimes occurs within an organization, such as the Castellamarese war of 1930–31 and the Boston Irish Mob Wars of the 1960s and 1970s.
Today criminal organizations are increasingly working together, realizing that it is better to work in cooperation rather than in competition with each other. This has led to the rise of global criminal organizations such as Mara Salvatrucha and the 18th Street gang. The Italian-American Mafia in the U.S. have had links with organized crime groups in Italy such as the Camorra, the 'Ndrangheta, the Rancitelli and Sacra Corona Unita. The Cosa Nostra has also been known to work with the Irish Mob (John Gotti of the Gambino family and James Coonan of the Westies are known to have worked together, with the Westies operating as a contract hit squad for the Gambino family after they helped Coonan come to power), the Japanese Yakuza and the Russian Mafia. The FBI estimates that global organized crime makes $1 trillion per year.
This rise in cooperation between criminal organizations has meant that law enforcement agencies are increasingly having to work together. The FBI operates an organized crime section from its headquarters in Washington, D.C. and is known to work with other national (e.g., Polizia di Stato, Russian Federal Security Service (FSB), and the Royal Canadian Mounted Police), federal (e.g., Bureau of Alcohol, Tobacco, Firearms, and Explosives, Drug Enforcement Administration, United States Marshals Service, and the United States Coast Guard), state (e.g., Massachusetts State Police Special Investigation Unit and the New York State Police Bureau of Criminal Investigation ) and city (e.g., New York City Police Department Organized Crime Unit and the Los Angeles Police Department Special Operations Division) law enforcement agencies.
