I think it is a damn shame and I hope some of his buddies find the one who did this.
But I can't help thinking that it is so typical American. My impression of the States is that it is prone to sharp reactions and emotions in a very short time. (Note: I am not trying to put anyone down, but this is the impression we get here in Holland.) On the one side you have this very patriotic group of people who can barely stand any criticism on any issue. On the other side you have this group trying to make a point by any means necessary. Obviously someone is trying to say he or she doesn't agree with this war, but why in such a disrespectful way? Why isn't there a mainstream path pro- and antagonists call talk without making unnecessary victims. This dead soldier's familie doesn't need this and America doesn't need this!
