As CAAFLog has pointed out, it appears that Major Hasan will be tried by media.
Someone at the National Capital Consortium, Psychiatry Residency Program, Walter Reed Army Medical Center has released a letter to the Credentials Committee. No word on the WRAMC AR 15-6 into this unauthorized disclosure.
One of the common “defenses” raised at trial is that the accused is a "Good Soldier.” Assuming evidence of this, usually through character witnesses and documents, the military judge is required to instruct the members that a “Good Soldier” defense can if believed and warranted be sufficient to create reasonable doubt at court-martial.
The disclosed letter does not appear helpful to a good soldier defense at court-martial, for Major Hasan at Fort Hood.
