both to the prosecutors and the judge. his offers were denied. you can explain why? >> reporter: well, those are the rules of the code of military justice, when someone is eligible for the death penalty, and that is what prosecutors are pursuing in this case, the zest not allowed to need not guilty. they had to put on a not guilty defense. it's strange, the judge started off by saying that major hasan had pleaded guilty. not an hour later, you saw hasan in the courtroom claiming he was the shooter and the evidence will clearly point to all of that. in many ways it was kind of surreal, it didn't seem like major hasan is in any way trying to prove his guilty or innocence. he seems bent on trying to justify what he had done. >> and how long is that expected to go on? >> reporter: it's interesting, many people thought it was going to take several months. they went through a dozen prosecution witnesses today.
