American politics is no more absurd than politics anywhere. Honestly. Trust me on this one. No new taxes.
Hamdi versus Rumsfeld - Supreme Court Ruling
The Supreme Court rules
Hamdi, an American citizen, can be detained as an enemy combatant, but has the right to U.S. courts. This is a ruling full of references which give one perspective on this issue from a historical point of view. For example:
"The object of capture is to prevent the captured individual from serving the enemy. He is disarmed and from then on must be removed as completely as practicable from the front, treated humanely, and in time exchanged, repatriated,or otherwise released."
