INTERPOL was founded in 1923 by the police of a few European countries. Today it has a membership roster of approximately 150 countries worldwide. It is financed almost entirely by membership dues and operates under a democratic constitution that specifies its adherence to the Universal Declaration of Human Rights. INTERPOL's "multinational police cooperation process" is its basic formula for counterassault on any targeted international crime. It has three steps: each country passes a law specifying the offense as a crime under its criminal code; each country prosecutes an offender in its own territory or cooperates in other countries' prosecutions, including extradition or expulsion when requested; and each country cooperates with and through INTERPOL in furnishing and exchanging information concerning the crime and its perpetrators. The crimes at the top of INTERPOL's concern are drug trafficking, terrorism, arms trafficking, and money laundering. It has developed special crime control systems applicable to these crimes.
