What message does Melchor send about the practice of victim-blaming in Chapter V and how does she send it?

Melchor is careful to make clear how disgustingly backwards the practice of victim-blaming is, particularly when applied to a child of Norma's age. The narrator states that the social worker gave orders that Norma was not to be untied for one second until she told them everything they wanted to know. Norma was tied to her bed and the order was given "to hold her prisoner there until the police arrived, or until Norma confessed" (88). The reader knows that Norma has nothing to confess and that in fact, she has been the victim of sexual abuse at the hands of her stepfather. Thus, the practice of victim-blaming is depicted as an incredibly destructive force, particularly when later, the narrator reveals that one nurse had chastised Norma for going off with her "legs akimbo" (90) and then being such a fool as to try to protect the culprit.
