The goals of Interpol, as an international criminal police organization, are to insure and promote the widest possible mutual assistance between member countries' criminal police authorities and to establish and develop institutions that will contribute effectively to preventing and suppressing crime. International drug trafficking presents one of the greatest challenges to law enforcement cooperation because some countries are hostile to foreign police investigations and because drug profits often corrupt foreign police agencies. The United States has Overseas Liaison Officers posted to countries throughout the world who represent such agencies as the Drug Enforcement Agency and the Federal Bureau of Investigation. These officers act as a clearinghouse for both U.S. and host country criminal intelligence needs. Scotland Yard uses computerized techniques to evaluate intelligence information and perform administrative tasks in criminal investigation. Both the United States and Great Britain use an analytical process known as ANACAPA that evaluates information and identifies areas where additional intelligence is needed.
