Everything that can be said about how insane brining GTMO terrorist to American soil for a domestic criminal trial has already been said, save that New York City has a lot of Muslims, so there are sure to be at least one on every relevant jury. That increases the chances for nullification.
But I have a rhetorical question — When in the early 1990s did the United States annex Afghanistan, such that the people there plotting 9/11 from ca. 1995 to 2001 are American citizens that have a Constitutional right to due process of the law?
