An injured soldier is helped down the stairs after meeting with US President Barack Obama before he addressed the Fort Hood community at III Corps Headquarters on Fort Hood Army Base in Fort Hood, Texas on November 10, 2009 during a memorial service for the soldiers and civilians killed on November 5, 2009. Obama said no faith could justify the Fort Hood rampage, in an address Tuesday memorializing victims of the accused gunman, Major Nidal Hasan, a devout Muslim.'It may be hard to comprehend the twisted logic that led to this tragedy,' Obama said in remarks.
