Terrorism and Extraterritorial Jurisdiction in Criminal Cases: Recent Developments in Brief [September 6, 2002] [open pdf - 912KB]
From the Summary: "Most crime is territorial. It is proscribed, investigated, tried, and punished under the law of the place where it occurs. As a general rule, no nation's laws apply within the territory of another. Yet in a surprising number of instances, federal criminal law does apply overseas to U.S. citizens and foreign nationals. As long as there is some nexus to the United States, federal law authorizes prosecution - practical, diplomatic, and procedural impediments notwithstanding. In the 107th Congress, the USA PATRIOT [Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism] Act and the legislation implementing the international conventions on terrorist bombings and on financing terrorism have extended the substantive authority for federal prosecution of crimes occurring elsewhere."
