Sexual abuse is also a secret crime, one that usually has no witness. Shame and secrecy keep a child from talking to siblings about the abuse, even if all the children in a family are being sexually assaulted. In contrast, if a child is physically or emotionally abused, the abuse is likely to occur in front of the other children in the family, at least some of the time. The physical and emotional abuse becomes part of the family's explicit history. Sexual abuse does not.
