In addition to damning people for their use of language, there is something sad about convicting a woman for smiling.

A woman is sometimes 'liked' because of her smile.  It is sometimes her charm.  Women smile for many reasons, including relief from pain or stress.  One can read all kinds of research regarding the power of 'the smile' from a physiological perspective and to believe people are using body language and smiling as a reason for commentary is quite astounding.  This isn't a game, she is fighting for her life.

For whatever it is worth, that smile looks very legitimate.  It is legal to smile.  Inmates in prison smile.

The change in facial expression by Casey during her trial is not at all unusual.  It is far easier to joke with a client than not.  It is better to be light-hearted when facing such extremes.  Sometimes there is no other way to approach such a harsh reality.  We, in the USA witness that 'humor' either dark humor or otherwise. 

But, when I heard to criticism in commentary by the media, I paid attention.

When the jury entered the room, the change in her facial expression reminded me of a woman and her lover when her husband walks in the room.  Follow?

I don't find any gravity to that weird idea, that guilt follows body language.  That's nonsense.  If it was that simple, the prosecution would have based their case on it.  That is a socail prejudice and nothing more.
