I do find this kind of debate fascinating, because it's about the extent to which people can, or should, lie in order to protect the feelings of others.
To some extent we all do it - if someone says "Do you like my new haircut?" there are very few who would say "No, it looks terrible."
I think we have to accept, however, that for some people the ethical imperative to tell the truth overrides the social obligation to be polite. This was certainly true for Jennifer Melle.
And the point, surely, is that however much you think that lying would be the polite thing to do*, you cannot, morally or legally, compel people to lie.
*I don't necessarily think it is the polite thing to do.
