There is no possibility that this will end well, no matter what the outcome.
1. This sets a precedent for granting Constitutional rights to non-citizens. This means that anyone in the world now has Constitutional rights. Does this mean that everyone in the world is subject to our laws as well? Then again, Obama does want to be president of the world...
2. If he is convicted, then Miranda rights and other arrest procedures would have been rendered null and void. The ramifications of this is dire. Sure, he's a non-citizen captured in a foreign land, but suppose someone decides to use this as a legal precedent and apply this to American citizens as well. The term 'Orwellian' seems to have been overused in this past decade (thanks to such idiots as the DUmmies and Kos Kooks), but this term certainly fits here.
3. If he is put in jail (let's say life in prison), he may be put away, but he will more than likey have some kind of influence within that prison. This could lead to possible terror attacks by other prisoners who have come in contact with him.
4. If he is set free, he will inevitably start planning on more attacks, and with this government still mired in the swamp that is political correctness, there is little doubt that he will succeed. He will also likely begin organizing other groups and consolidating Al'Qaeda's power. He might very well end up being what Osama was back in the 90s.
5. There will be a whole lot of classified information that will be released throughout this trial, information that Al'Qaeda is just itching to get their hands on, information that will no doubt further cripple the US.
6. The tin hat crowd and the other DUmmies will have a smorgasbord over this, and will try to make this trial justify their insane conspiracy theories.
7. In the end, this entire trial is nothing more than the latest attempt to criminalize conservatism, patriotism, and opposition in general to the socialist/fascist agenda.
