Not long after Major Nidal Malik Hasan pulled the trigger for the last time at Ft. Hood, the mainstream media began assembling their preposterous, anything-but-Islam narratives. A rationale was needed, something that could plausibly be claimed to motivate a killing spree. A desperate rush to explain his behavior in politically palatable terms naturally resulted in desperate stories in which preposterous motivations contrary to the known facts were posited.
Among the first possible reasons for Hasan's actions submitted was that he had Post Traumatic Stress Disorder (PTSD). Ever since the Vietnam War, media swells have peddled the stereotype of the psychologically traumatized veteran ready to snap. So of course, some of them made fools of themselves.
