U.S. v. Verdugo-Urquidez "These cases, however, establish only that aliens receive constitutional protections when they have come within the territory of the United States
and developed substantial connections with this country."
I think this is a reasonable line to draw. You are welcome to have a different opinion.
A question one must first decide is whether the terrorist acts were "acts of war".
If they were they should be tried by military tribunal.
Thank you for the reference. I will look it up and read it. I think that what you have quoted may be a good line to draw, too. I doubt that someone who came secretly and illegally into the United States the night before the act of terrorism for the sole purpose of committing the act of terrorism is entitled can claim Constitutional protection.
But the question then becomes, who decides that that is what happened and how?
