FORT HOOD, Texas — Maj. Nidal Malik Hasan fired the last of 146 bullets in his assault on Fort Hood, then walked outside where he met two civilians who asked about the commotion and the laser-sighted pistol in his hand.
Hasan told one person not to worry. He assured the other it was just a training exercise and the gun shot only paint. He let both live.
But moments earlier, dozens of uniformed soldiers received no quarter from Hasan, prosecutors said Tuesday as the Army psychiatrist's long-delayed trial began in a Texas military courtroom.
With his life hanging in the balance, Hasan made little effort to defend himself. Acting as his own attorney, he calmly told the jury that he killed 13 people and wounded 32 others in the 2009 attack.
"The evidence will clearly show that I am the shooter," he said in an opening statement that lasted little more than a minute The evidence, he added, would "only show one side."
His only utterance of regret was an acknowledgement that he was among "imperfect Muslims trying to establish the perfect religion."
"I apologize for any mistakes I made in this endeavor," said Hasan, an American-born 42-year-old who was paralyzed after being shot by officers responding to the attack. He spoke from a wheelchair, wearing green Army fatigues and a gray, bushy beard.
Hasan planned the assault for months, prosecutor Col. Steve Henricks said, describing how the defendant stockpiled bullets, practiced at a shooting range and bought an extender kit so his pistol could hold more bullets.
