There is NOTHING " extralegal " about a miltary tribunal. George Washington , Lincoln, and FDR all used them.
The Taliban , members of al Qaeda, OBL, and Mullah Omar, are NOT citizens of the USA, they aren't in the USA, and those members of sleeper cells here , aren't citizens either. Please state chapter and vers, AND your source for miltary tribunals being " extralegal ", or admit that you are wrong.
