[00:00.00]President Barack Obama has told the memorial service at the Fort Hood army base in Texas that the Untied States must never forget the 13 men and women who died in the shooting there last week. He said the killings couldn’t be justified. “ It may be hard to comprehend the twisted logic that led to this tragedy. But this much we do know, no faith justifies these murderous and craven acts. No just and loving God looks upon them with favor. For what he’s done, we know that the killer will be met with justice in this world and the next. “ The president paid tribute to those who'd not been able, as he put it, to escape the horror of war even in the comfort of home. Federal officials are looking for possible links between Major Nidal Hasan, the army psychiatrist accused of the killings and a radical Muslim cleric now living in Yemen.
