Who is an Unlawful Enemy Combatant?

So now that the Senate has officially agreed to sponsor torture on "unlawful enemy combatants", the Bush administration has come out with their definition of what an "unlawful enemy combatant" is. From Democratic Undergound...

According to this Act, an "unlawful enemy combatant" is to be defined as:
"an individual engaged in hostilities against the United States who is not a lawful enemy combatant."

This basically means that if a person is not a soldier in the service of a foreign government, but is nevertheless engaging in "hostilities" against the United States, then this person is an unlawful enemy combatant. Notice that this definition does not require that such a person be an "alien," which accordingly leaves open the possibility that this designation could also be applied to an American citizen.

I think I am going to rent V is for Vendetta tonight and watch it again.
