Wow, you learned something already! I'm impressed.
So your new claim is that the Constitution should be changed to give the Judicial Branch exactly what new power so they can do more than hold a habeas corpus hearing for an accused citizen combatant?
No. My claim is that Mr. Padilla is accused of levying war against our country. And the Constitution explicitly defines this behavior as the crime of Treason. Furthermore, the Constitution guarantees those accused of Treason a trial, during which no fewer than two witnesses must testify in order to gain a conviction.
That is what the Constitution says, in very plain words that even the most obtuse individual can understand. I advocate no changes to the Constitution, rather I would prefer that our government adhere to its crystal clear mandates in this case.
This really isn't all that difficult to understand.
