do a google search on the lady. In a number of interviews {none interrupted by her grieving} she says Bush has a personal vendetta war, she says her son's unit wasn't prepared, swears the govt wouldn't let her into dover to see his body {betcha she had a camera}. Many many interviews and complaints that the army is lying to her, and so on.
In short, she has a peculiar grief that seems to manifest itself by wearing tee shirts, yelling at public meetings, giving non stop interviews, going to marches. I don't know. Somehow I imagine grief as a more weeping, crying, holding onto loved ones.
She really could use a trained therapist.
