Fort Hood suspect's defense: Islamic leadership was in danger

Updated 3:26 p.m. ET

FORT HOOD, Texas An Army psychiatrist charged with gunning down Fort Hood soldiers waiting to deploy to Afghanistan said Tuesday his defense would show that he was compelled to do so because the troops posed an imminent danger to Taliban fighters.

The military judge asked Maj. Nidal Hasan if he has evidence to support his "defense of others" strategy, hinting that it could be thrown out.

The "defense of others" defense requires him to prove the killings were necessary to protect others from immediate danger or death.

The court-martial had been scheduled to start with jury selection Wednesday, two days after Hasan was granted his request to represent himself. Hasan, an American-born Muslim, then requested a three-month delay to give him more time to prepare his defense.

The military judge, Col. Tara Osborn, was to rule Wednesday on Hasan's trial delay request. Osborn said jury selection would now start no earlier than Monday.

Hasan, 42, faces the death penalty or life without parole if convicted of 13 counts of premeditated murder and 32 counts of attempted premeditated murder in the 2009 attack at the Army post in Texas.

At a hearing Tuesday, Osborn asked what evidence he had to support his defense. He said Taliban leader Mullah Omar and "leadership of the Taliban in general" were in immediate danger from American troops on the Texas Army post, because "the U.S. has attacked and continued to attack the Taliban."

Osborn quickly interrupted Hasan, a day after telling him that he could not make speeches or try to testify when questioning witnesses.

Military law experts not involved in the case said they believe the judge won't allow Hasan to present that defense.

"A `defense of others' strategy is not going to work when you're at war and the `others' are enemies of the U.S.," said Jeff Addicott, director of the Center for Terrorism Law at St. Mary's University in San Antonio. "And what makes it more egregious is that he targeted medical personnel whose primary purpose was to heal, not to kill."

Retired Staff Sgt. Shawn Manning, shot six times that day, said five of the 13 killed at Fort Hood were in two units that had been training to help soldiers deal with stress. Deployed soldiers in those units are allowed to fire their weapons only in self-defense, Manning said. Hasan was to deploy to Afghanistan with one of those units.

"It makes me sick to my stomach" that Hasan is using such a defense strategy, Manning said.

Witnesses have said that after lunch on Nov. 5, 2009, a gunman wearing an Army combat uniform shouted "Allahu Akbar!" — "God is great!" in Arabic — and opened fire in a crowded medical building where deploying soldiers get vaccines and tests. Witnesses said the gunman fired rapidly, pausing only to reload, even shooting at some soldiers as they hid under desks and fled the building.

Government documents show that in the years before the shooting, Hasan told some colleagues that the U.S. was at war with Islam. In some emails to a radical Muslim cleric, Hasan indicated that he supported terrorists and was intrigued with the idea of U.S. soldiers killing comrades in the name of Islam.
