Ohhh, I see what you're saying. That's true, I suppose Obama could. He won't, and I don't see the benefits of it vs allowing the bomber to go through the American justice system though.
Ok. That's a much richer vein for discussion.
The benefits include NOT having to provide the "defendant" with "discovery" which could (depending on the case) force the government to reveal HOW it obtains some intel.
I see zero value in educating our opponents in a war against terrorists.
I see great value in denying the enemy any intel.
Similarly, if we insist that this matter is JUST a criminal case (as opposed to an act or acts of war), then it may very well be true that the "defendant" is "entitled" to
Miranda warnings. We treat him differently (and intentionally so) not just on the possible pain of not being able to use his statements as evidence against him at trial, but at the risk that he might be able to craft an appeals argument (after conviction) that he was denied equal protection of the law and denied a "fair" trial if we find that we cannot give him some discovery, etc.
And let's be real. Alhough it is a long shot, this is the American system of law we are talking about. That means that there is a true possibility that some jury could acquit him no matter how ******* guilty he is. For our mere criminals (like rapists and murderers and robbers and car thieves, etc) that's a risk we are more than willing to face every day.
But if some U.S. citizen active terrorist member of al qaeda (this example doesn't necessarily involve Tsarnaev) has done something along the lines of what Tsarnaev did, possibly with radiological dirty bombs, etc., what the **** are we supposed to do if he is nevertheless found "not guilty?" Are we actually prepared to return such a piece of shit to the amorphous battlefield? Should we be?
There is so much wrong with treating illegal combatant citizens as mere criminals and using our justice courts as the vehicles to go after them, it is potentially suicidal to willingly CHOOSE that option.
It was FINE and dandy, legally, in the
Quirin case, to use a military tribunal against U.S. citizen combatants. The history does go all the way back to George Washington.
But now? Somehow, for reasons that don't make any damn actual sense, the "rules" they are a-changin'.
The trouble is, they shouldn't be.
