Fort Hood Massacre

An army Major who was a psychiatrist treating post traumatic stress in soldiers returning from Iraq and Afghanistan killed 13 and wounded 30 at Fort Hood, Texas, in a one-man massacre, Nov 6 2009.

Chuck Medley, director of emergency services at the Army post, said at a press conference that the first call of shots being fired came at 2:22 p.m. ET (19:22:51 GMT) and that civilian officer Sgt. Kimberly Munley arrived at the scene five minutes later to find Hasan chasing and firing at a soldier outside the readiness building.

Hasan, a U.S. citizen born in Virginia to Palestinian parents, was wounded by a civilian police officer who responded to the shooting rampage that is believed to be the worst ever at a U.S. military installation, said Lt. Gen. Robert Cone, commanding general of Fort Hood.

It is important to keep in mind that we have only a tiny statistical effect, so that it is always hard to distinguish signal from noise. This means that every "success" might be largely driven by chance, and every "null" might include a real signal overwhelmed by noise. In the long run, a real effect can be identified only by patiently accumulating replications of similar analyses.
