Well if it isn't the old "Concentration Camp Guard" defense. No, he was not given a lawful order. This war is an illegal war, started by the use of lies and false pretenses in order to secure a congressional resolution. Waged by criminals, no soldier in this conflict has been given any "lawful order", and rather than "dishonor" her son, she honors his sacrifice by exercising the rights he thought he was dying for to protest his useless death. She earned that right.
