Signs that the Fort Hood gunman could snap emerged not just days before his deadly rampage, but months earlier, say witnesses. Major Nidal Malik Hasan bought a gun soon after he arrived at the base last summer, and grew increasingly agitated and vocal over years about his opposition to the wars in Iraq and Afghanistan. The psychiatrist tried desperately to get an early army discharge but was instead about to be shipped out to Afghanistan. "He was obviously upset," said a friend.
Hasan was so conflicted that he delivered a Power Point presentation to students in an environmental health seminar at Walter Reed entitled “Why the War on Terror Is a War on Islam.” The presentation was so disturbing to some that they complained to authorities, reports the New York Times. Yet Hasan's superiors believed he was not a threat. “He swore an oath of loyalty to the military,” said his supervisor. “I didn’t hear anything contrary to those oaths.”
