Could the Ft. Hood shooting have been prevented? A Defense Department review of the attack says yes, and its findings could mean disciplinary action against five to eight Army officers who did not take action against the alleged shooter, Maj. Nidal Malik Hasan, after he demonstrated suspicious and dangerous behavior. According to the review, Hasan failed to meet professional and physical standards for his Army psychiatrist job even while his superiors allowed him to continue to advance. "Had those failings been properly adjudicated, he wouldn't have progressed," an official familiar with the review told the Los Angeles Times.
