Honestly? I think your average person on the street - who is not a Websleuth type, who doesn't obsess over murders and such, believe that the only time you are sure of a Guilty verdict is if you have a body, blood and fingerprints and a murder weapon and preferably CCTV or witnesses to the crime itself.
So many people commenting off Websleuth on the Joy Morgan case saying 'how can they charge him with murder if there's no body?' ... but they can and did and the jury took 11 hours to vote a unanimous guilty with far fewer things not adding up than in this case.
