I'm willing to see the government hold a citizen like Padilla without trial if it can satisfy a court that it has reasonably classified him as an enemy combatant. What has really troubled me about the government's position is that it has claimed it shouldn't have to make such a showing to a court.
Padilla should be charged with a crime to be held as a prisoner. It seems that after 7 months of being held prisoner the government still does not have the ability to charge him with a crime and that there is virtually no case against him.
As far as an enemy combatant goes, seriously, what evidence has been presented to show that his detention is vital to the security of the United States or that he was actually involved in 'combating' the US?
