HALLOWELL, MEWhile waiting for a bus Tuesday, Stan Geraldson watched 2-year-old Jason Kemper pick up a spent cigarette butt and place it in his mouth, but made only a minor attempt to stop him. 'Hey, ah, you shouldn't...' Geraldson told Kemper, whose mother was engaged in a conversation a few feet away. 'Don't... eat that.' Geraldson said he would have done more to stop Kemper if the item had been fiberglass or something.
