Corruption may facilitate criminal enterprise such as drug trafficking, money laundering, and human trafficking, though is not restricted to these activities. Misuse of government power for other purposes, such as repression of political opponents and general police brutality, is not considered political corruption. Neither are illegal acts by private persons or corporations not directly involved with the government.
Electoral fraud is illegal interference with the process of an election. Acts of fraud affect vote counts to bring about an election result, whether by increasing the vote share of the favored candidate, depressing the vote share of the rival candidates, or both. Also called voter fraud, the mechanisms involved include illegal voter registration, intimidation at polls, and improper vote counting.
Embezzlement is theft of entrusted funds. It is political when it involves public money taken by a public official for use by anyone not specified by the public. A common type of embezzlement is that of personal use of entrusted government resources; for example, when an official assigns public employees to renovate his own house.
A kickback is an official’s share of misappropriated funds allocated from his or her organization to an organization involved in corrupt bidding. For example, suppose that a politician is in charge of choosing how to spend some public funds. He can give a contract to a company that is not the best bidder, or allocate more than they deserve. In this case, the company benefits, and in exchange for betraying the public, the official receives a kickback payment, which is a portion of the sum the company received. This sum itself may be all or a portion of the difference between the actual (inflated) payment to the company and the (lower) market-based price that would have been paid had the bidding been competitive.
Another example of a kickback would be if a judge receives a portion of the profits that a business makes in exchange for his judicial decisions.
Kickbacks are not limited to government officials; any situation in which people are entrusted to spend funds that do not belong to them are susceptible to this kind of corruption.
An illustrative example of official involvement in organized crime can be found from 1920s and 1930s Shanghai, where Huang Jinrong was a police chief in the French concession, while simultaneously being a gang boss and co-operating with Du Yuesheng, the local gang ringleader. The relationship kept the flow of profits from the gang’s gambling dens, prostitution, and protection rackets undisturbed.
The United States accused Manuel Noriega’s government in Panama of being a “narcokleptocracy”, a corrupt government profiting on illegal drug trade. Later the U.S. invaded Panama and captured Noriega.
