Charles Taylor, the former president of Liberia, is now a convicted war criminal. An international tribunal at the Hague found Taylor guilty of committing murder, rape, slavery and the use of child soldiers during Sierra Leone’s civil war in the 1990s. Taylor is the first head of state to be convicted by an international court since Hitler’s successor stood trial following World War Two. Leanna Orr spoke with Peter Rosenblum, a professor of human rights law at Columbia University, about the significance of Taylor’s conviction.
