CarolC, I will give you my opinion. When I was in Vietnam the only "fraggings" I knew about were directed against particular individuals, ie, incompetent officers who put far too many troops in harms way knowing full well their's was a fool's errand. Whether they deserved what they got? Debatable. Those in command had the discretion to countermand or question orders from superiors that were foolhardy or ineffective or just plain stupid. The incident in question (in this thread) is a random act of terror directed at as many people as possible. It is my belief that this person may have acted in accordance with his muslin beliefs to kill "infidels". Or he may be part of a terrorist cell.
