Amanda Knox defends her comedy show at Edinburgh festival as honoring her murdered former roommate(Photo/MGN)LONDON (AP) — Amanda Knox, the American student convicted and later acquitted of the murder and sexual assault of her British roommate Meredith Kercher 19 years ago in Italy, is defending herself against accusations from Kercher’s sister that her comedy show at the Edinburgh Fringe festival in Scotland trivializes violence against women. Knox, now 39, said Thursday in a post on Instagram that her show “honors Meredith Kercher’s memory and calls out the violence that was done to her and to me.” The show is called “Cartwheel,” a reference to a story that claimed Knox did cartwheels in the police station after Kercher’s death. The case made global headlines as suspicion quickly fell on Knox and her boyfriend of just days, Raffaele Sollecito. Knox’s post follows an interview that Meredith Kercher’s sister, Stephanie Kercher, gave to the BBC during which she said the show “normalizes and trivializes violence against women.”
