Meredith Kercher's sister criticises Amanda Knox comedy show

Stephanie Kercher has criticised Amanda Knox's Edinburgh Fringe comedy show, 'Cartwheel', saying her sister Meredith would find no comedy value in it. Knox, acquitted of Meredith's 2007 murder in Italy, says the show honours her memory and she does not joke about her death. A petition against the show has over 2,400 signatures.
