From the info I have read from the trial, he represented himself like this
During the sentencing phase on Tuesday, he rested his case without offering any witnesses or providing evidence in favour of a life sentence.
and this, and this
On Thursday, he told the judge: "The defence chooses not to make a closing statement."
His court-appointed lawyers, whom he has barely used, have argued he is intent on securing the death penalty in a bid for martyrdom.
Maj Hasan has refused to call anyone to the stand and questioned only three of the 90 prosecution witnesses.
His court-appointed legal advisers tried to step in on his behalf.
But military judge Col Tara Osborn denied their request, saying Maj Hasan had the constitutional right to represent himself.
"It is my free and voluntary decision," he told her.
There's only one reason why I don't think he should executed: to make sure Al-Quaeda & Co. don't use him as a martyr.
So, I hope he spends the rest of his life in Death Row doing appeals and that he dies before they run their course.
