Perception was everything last night in Garfield Kennedy’s fascinating if, at times, frustrating documentary, The Trials of Amanda Knox. Was the American student who was convicted last month of murdering her British flatmate in Perugia, Meredith Kercher, a scheming hussy into (very) extreme sex games, or just an averagely adventurous twentysomething turned into a scapegoat by an Italian judiciary that had already convinced itself of her guilt? Kennedy’s film considered the evidence, and it also detailed the concomitant trial by the media - and there, to a degree, is a problem. Because this documentary is also “the media”, and Knox’s case (appeal pending) is not closed. Somewhat misleadingly, it could be argued, the film was screening in More4’s True Stories slot. But was this only the partial truth, with some added special pleading?
