It has nothing to do with the morality of the law  , it's about her appearing to have no remorse over breaking a legal law on the books.   If you think that law is wrong , it's easy to contact legislators and have the law removed.  Given the current movement to have laws taken off the books , you get it done and you'll be a hero to some.       Another consideration is that when a guy named Jesus came across people stoning a prostitute , he told them that he who is without sin to cast the first stone. He also told the lady to go and sin no more. Jesus seemed to have a pretty good take on what was moral and what was not.
