Excellent article at The New Ledger, How the Fort Hood Shooter Will be Judged.
The author expects the defense counsel to properly use the remarks Obama will make at the funerals as grounds for an argument to set aside the death penalty. It is worth reading.

My comments follow;
What would be appropriate for a POTUS to say without interfering with the trial?
1. He can praise the fallen, their honor and sacrifice and the ideals they died for.
2. He can praise the Constitution, the American system of law and justice that they swore to defend.
3. He can praise the healing nature and essential goodness of our culture as a source of hope for all.
4. He can quote sources of our culture, the Old and New Testaments and Pericles Funeral Oration.
5. He can cite other tough moments when our sense of justice was tested but triumphed.
6. He can assure all that Justice will be done.

Rock,
Well said.
