In 2010, part of then-Secretary of Defense Robert Gates' response to the shooting was to "strengthen [the department's] policies, programs and procedures in... workplace violence." In October 2011, the Defense Department said it was reviewing the attack "in the context of a broader threat of workplace violence."
Rubinstein and his partner, Neil Sher, also said calling the attack "an alleged criminal act by a single individual" "rewrites history, consigning the government's admissions of Hasan's al-Qaeda ties… down a bureaucratic memory hole."
Munley said, "It is clear that the Army and the government will continue to not take responsibility for allowing a known terrorist to slip through the ranks while having multiple associations with the now-deceased Anwar al-Awlaki and has complete disregard for those injured on that horrifying day."
In Chipman's letter, he said the Army is willing to reconsider their classification of the event should "new, relevant evidence" arise.
"The Army's decision, in no way, diminishes the common goal of ensuring the victims are treated and cared for promptly and compassionately," the letter says. "Although we cannot undo the outcome of that day, taking care of those affected by the Fort Hood shooting... remains one of the Army's top priorities."
