Prayer shawls are worn by men, so that is the law?? The only requirement at the Wall is modesty for both men and woman. This is more of orthodoxy trying to mopolise the Wall by intimidation. As long as the woman was quiet and respectful as we all should be , I see no problem here at all. Yes she may be a wacko according to Orthodoxy but orthodox Judaism does not represent all Jews, though it likes to think so.
