Yesterday, a thirty-nine-year-old, never-married Army psychiatrist with expertise in disaster and preventive psychiatry allegedly gunned down thirteen men and women, wounding thirty-eight. The murderous incident took place at Fort Hood, a military base in Texas where soldiers were being prepared for deployment to Iraq and Afghanistan. Though the suspected perpetrator, Major Nidal Malik Hasan had initially been reported killed by military police, we now know he was seriously wounded, is currently in a coma, but expected to survive. What could possibly possess an apparently polite, pleasant, quiet, reserved, compassionate, empathetic, forgiving and deeply religious Army psychiatrist to commit this incredibly evil deed?
