Several forms of racket exist. The best-known is the protection racket, in which criminals demand money from businesses in exchange for the service of "protection" against crimes that the racketeers themselves instigate if unpaid. A second well known example is the numbers racket, a form of illegal lottery.
The term racket comes from the Italian word ricatto (blackmail) and is also used as a pejorative term for legitimate businesses. Typically, this usage is based on the example of the "protection racket" and indicates that the speaker believes that the business is making money by selling a solution to a problem that it created (or that it intentionally allows to continue to exist), specifically so that continuous purchases of the solution are always needed. Racket businesses in the past have been noted to be hidden in different parts of buildings, perhaps most notibly in basement areas.
The term was also used to describe the lavish parties thrown by gangs (circa 1850) located in the Five Points (New York City). Corrupt politicians sold tickets to these parties through coercion and threatening ultimatums.
On October 15, 1970, the Racketeer Influenced and Corrupt Organizations Act (18 U.S.C. §§ 1961-1968), commonly referred to as the "RICO Act", became law. The RICO Act allowed law enforcement to charge a person or group with racketeering, defined as committing multiple violations of certain varieties within a 10 year period. The purpose of the RICO Act was stated as "the elimination of the infiltration of organized crime and racketeering into legitimate organizations operating in interstate commerce." S.Rep. No. 617, 91st Cong., 1st Sess. 76 (1969). However, the statute is sufficiently broad to encompass illegal activities relating to any enterprise affecting interstate or foreign commerce. Section 1961(10) of Title 18 provides that the Attorney General may designate any department or agency to conduct investigations authorized by the RICO statute and such department or agency may use the investigative provisions of the statute or the investigative power of such department or agency otherwise conferred by law. Absent a specific designation by the Attorney General, jurisdiction to conduct investigations for violations of 18 U.S.C. § 1962 lies with the agency having jurisdiction over the violations constituting the pattern of racketeering activity listed in 18 U.S.C. § 1961.
In The United States of America, civil racketeering laws are also used in their federal and state courts. The National Federation of Independent Business has challenged these civil laws for being excessively abusive.
