A woman wearing a T-shirt with the words "President Bush You Killed My Son" and a picture of a soldier killed in Iraq was detained Thursday after she interrupted a campaign speech by first lady Laura Bush. As shouts of "Four More Years" subsided, Niederer, standing in the middle of a crowd of some 700, continued to shout about the killing of her son. Local police escorted her from the event, handcuffed her and put her in the back of a police van.
