I wonder if Cindy Sheehan has given even a moment's thought to what her son Casey might think of her activities since his death. I don't presume to know what he would think, but the fact that he did volunteer to serve in the armed forces suggests that he might have looked on the war in Iraq differently than his mother does.
If that did happen to be the case, is it right for her to use his memory to score political points against a president she dislikes? Maybe not... . Note that her family has asked her to stop.
