I don't have time to comment on this right now, but please note this article by Adam Liptak in Sunday's New York Times concerning a class-action lawsuit filed in Florida last September against a number of wealthy individuals in the United Arab Emirates. Asserting the federal court's jurisdiction under the 1789 Alien Tort Statute, attorneys for the plaintiffs--young camel jockeys who worked in the UAE, and their parents--allege that the owners of racing camels in the UAE abducted children from their homes in various South Asian countries and kept them in conditions of slavery, both violations of the law of nations as required by the Alien Tort Statute.
