On December 17, 2009, President Barack H. Obama signed Executive Order 12425 which alters how INTERPOL, the international policing organization, may operate within the United States. The order amends an executive order of the same number, signed by Reagan in 1983. The amendment removes a provision of the executive order which amended the Interational Organizations Immunities Act (22 U.S.C. 288). It removes several caveats of the Act designed to limit law enforcement activities by foreign nations within American borders.
This basically removes most of the restrictions on foreign investigations (usually conducted via INTERPOL). It also seriously undermines U.S. national sovereignty.
