It's good - if sobering - to see the specifics in the NYT:
Witnesses said that the floor became drenched with blood and that soldiers, apparently dead, were draped over chairs in the waiting area or lying on the floor.
Specialist Matthew Cooke, 30, who was expecting orders to leave for Afghanistan in January, was waiting in line to be processed in the medical building when Major Hasan opened fire. A soldier standing near him was hit and crumpled to the ground, and Specialist Cooke dropped to his knees and leaned over the soldier to shield him from being struck again, Specialist Cooke’s father, Carl, said in an interview.
Major Hasan walked up to Specialist Cooke, who had previously done a tour in Iraq, pointed his gun down at his back and shot him several times, Mr. Cooke said. “The rounds nicked his colon and several places in his intestines, bladder and spleen,” he said, but the specialist survived.
These human beings - citizens who risked their lives for the rest of us - were gunned down defenseless as they sought medical help. Because of religious fanaticism.
