Almost four years after the Fort Hood massacre, Nidal Hasan is expected to try to justify why he killed 13 unarmed fellow soldiers and wounded more than 30 others, CNN's Ed Lavandera reports.
Hasan, who's an Army psychiatrist, has been told he can not argue he killed American soldiers because in his view they were preparing to fight Muslims in Afghanistan and Iraq.
Since Hasan is acting as his own attorney, he will write out a series of questions for his "standby attorneys" to ask him.
Shooting survivor Christopher Royal has worked to already move on from the tragic event.
"I wont allow him to consume any more energy for my life than he has already done. And so I have released him. I have forgiven him completely. It's not up to me to punish him."
