Actually there was a case recently of an old man who had been dead in his apartment in Australia for a year.

And yes people were ashamed of themselves because they felt it was indicative of a breakdown in community.

Do you feel the crime represents the general disintegration of the community/moral values??? Then yes people should be ashamed.

And no I haven't forgotten the burning of witches a few hundred years ago a present day analogy would be when there are mob attacks on paedophiles.
