"the reactions of two people who just lost a beautiful child, extremely cold and lacking in emotion "

That was precisely the kind of thing that was said about Linda Chamberlain, and about other women who have been falsely accused, falsely convicted, and wrongly jailed for killing their children - and later exonerated. It's the kind of shallow accusation made of women who have been raped but who are disbelieved because they do not react in an openly emotional way.

People react to trauma in many ways, very often in ways that are seen as "cold and lacking in emotion".
