Amanda Knox, acquitted after an Italian court conviction in the 2007 murder of roommate Meredith Kercher, is performing a stand-up routine titled 'Cartwheel' at Scotland's Edinburgh Fringe Festival. The Kercher family has described the show as insensitive and exploitative. Knox has cited her legal acquittal on flawed DNA evidence and has previously written books and served as executive producer on a Hulu series about the case.
