It's a law thing. The news should report what laws were broken, not editorialize what a crime should be called. Tell your congressman to change the wording of the law if this bothers you and you live in this particular jurisdiction. Also, she didn't have sex with the kid. She tried but her husband walked in before it happened. Even if the law says a woman can rape a boy (as it should) she didn't in this case. At best it's attempted. Assault and sexual abuse fit the events just fine.
