At the end of a tattered, sunbaked runway dotted with large green tents here is a building aptly called the Expeditionary Legal Complex Courtroom, surrounded by coils of concertina wire, where the most notorious alleged terrorists in U.S. custody are supposed to face charges related to the Sept. 11, 2001, attacks. Nearly seven years later, however, not one of the approximately 775 terrorism suspects who have been held on this island has faced a jury trial inside the new complex, and U.S. officials think it is highly unlikely that any of the Sept. 11 suspects will before the Bush administration ends.
