Is this 9/11 related? without knowing the background of the soldier in question but it seems he's been in 11 years(joining at the time or close to 9/11)Did this happen because how that may have affected him?Is this delayed "revenge" for that? The hard part for me why so many children?Adults yes ,Adults can be threats if he had shot only Adults I could almost" jam with that" but children, surely the general consensus is children are not threating?Why so many especially since he's a father ,does he have a child related tragedy in his past perhaps 9/11 related? Of course he might just be a complete and utter fruitcake.
