Due to the nature of the charges (more than one premeditated, or first-degree, murder case, in a single crime), Hasan faced either the death penalty or life in prison without parole upon conviction.

The U.S. government declined requests from survivors and family members of the slain to categorize the Fort Hood shooting as an act of terrorism, or motivated by militant Islamic religious convictions.

[10] According to pretrial testimony, Hasan entered the Guns Galore store in Killeen on July 31, 2009, and purchased the FN Five-seven semi-automatic pistol that he would use in the attack at Fort Hood.

[13] In the weeks prior to the attack, Hasan visited an outdoor shooting range in Florence, where he allegedly became adept at hitting silhouette targets at distances of up to 100 yards.

[12] At approximately 1:34 p.m. local time, November 5, 2009, Hasan entered the Soldier Readiness Processing Center, where personnel receive routine medical treatment immediately prior to and on return from deployment.

[24] Army Reserve Specialist Logan Burnett tried to stop Hasan by throwing a folding table at him, but he was shot in the left hip, fell down, and crawled to a nearby cubicle.

Base civilian police Sergeant Kimberly Munley, who had rushed to the scene in her patrol car, encountered Hasan in the area outside the Soldier Readiness Processing Center.

Immediately after the shooting, the base and surrounding areas were locked down by military police and U.S. Army Criminal Investigation Command (CID) until around 7 pm local time.

[69] The 13 killed were: The following people suffered gunshot wounds and survived: During his court-martial on August 6, 2013 before a panel of 13 officers, Major Nidal Malik Hasan declared that he was the shooter.

[113] Once, while presenting what was supposed to be a medical lecture to other psychiatrists, Hasan talked about Islam, and said that, according to the Quran, non-believers would be sent to hell, decapitated, set on fire, and have burning oil poured down their throats.

[116] He also handed out copies of the Quran, along with his business cards, which gave a Maryland phone number and read "Behavioral Heatlh [sic] – Mental Health – Life Skills | Nidal Hasan, MD, MPH | SoA(SWT) | Psychiatrist".

Awlaki had been the subject of several FBI investigations, and had helped hijackers al-Hazmi and Hanjour settle, and provided spiritual guidance to them when they met him at the San Diego mosque, and after they drove to the east coast.

[127] Army employees were informed of the contacts at the time, but they believed that the e-mails were consistent with Hasan's professional mental health research about Muslims in the armed services, as part of his master's work in Disaster and Preventive Psychiatry.

[142] Retired General Barry McCaffrey said on Anderson Cooper 360° that "it's starting to appear as if this was a domestic terrorist attack on fellow soldiers by a major in the Army who we educated for six years while he was giving off these vibes of disloyalty to his own force".

[143] Some of Hasan's former colleagues have said he performed substandard work and occasionally unnerved them by expressing fervent Islamic views and deep opposition to the U.S.-led wars in Iraq and Afghanistan.

[148] Two weeks after recommending no conclusions be drawn until after the investigation was completed, Senator Joe Lieberman called the shooting "the most destructive terrorist attack on America since September 11, 2001."

Obama was criticized by various news outlets for being "insensitive" to viewer's perceived emotional distress, speaking too colloquially by giving a "shout-out" to a member of the audience and assuming a "jocular" tone for the first three minutes of his speech rather than immediately according the moment sufficient gravitas.

Retired Army colonel Terry Lee, who had worked with Hasan, said the psychiatrist expressed the hope that Obama would withdraw U.S. troops from Iraq and Afghanistan, and argued with military colleagues who supported the wars.

The U.S. government declined requests from survivors and family members of the slain to categorize the Fort Hood shooting as an act of terrorism, or motivated by militant Islamic religious convictions.

[198] According to a November 11 press release, after preliminary examination of Hasan's computers and internet activity, they had found no information to indicate he had any co-conspirators or was part of a broader terrorist plot, stressing the "early stages" of the review.

[200] For ten years, Hasan prayed several times a week at the Muslim Community Center in Silver Spring, Maryland, closer to where he lived and worked.

[211] Having previously instructed Hasan to follow Army regulations and shave a beard he had grown, the judge, Colonel Gregory Gross, found him in contempt in July 2012 and fined him.

[216] On September 6, Gross ordered that Hasan be shaved after it was determined that the 1993 Religious Freedom Restoration Act did not apply to this case; however, it will not be enforced until his appeals are exhausted, further delaying the trial.

[227] In 2011 Osborn presided over a death penalty case, the court martial of SGT Joseph Bozicevich, who was sentenced to life in prison without possibility of parole for killing his squad leader and another soldier.

[245] James Corum, a retired Army Reserve Lieutenant Colonel and Dean at the Baltic Defence College in Estonia, called the Defense Department report "a travesty", for failing to mention Hasan's devotion to Islam and his radicalization.

[247] John Lehman, a member of the 9/11 Commission and Secretary of the Navy under Ronald Reagan, said he felt that the report "shows you how deeply entrenched the values of political correctness have become.

"[245] The columnist Debra Saunders of the San Francisco Chronicle wrote in an opinion piece: "Even ... if the report's purpose was to craft lessons to prevent future attacks, how could they leave out radical Islam?

[253] In November 2013, Army Secretary John M. McHugh is quoted as writing that he has "directed my staff to conduct a thorough review of the record of trial in the court-martial of Major Hasan to ascertain if those proceedings revealed new evidence or information that establishes clearly the necessary link to international terrorism".

[254] A lawsuit filed in November 2011 by victims and their family members alleges that the government's failure to take action against Hasan before the attack was willful negligence prompted by "political correctness".

[9] US Representatives John R. Carter and Michael T. McCaul wrote, "Based on all the facts, it is inconceivable to us that the DOD and the Army continue to label this attack 'workplace violence' in spite of all the evidence that clearly proves the Fort Hood shooting was an act of terror.
