The Vanni is by any standards an important project. A significant voice in the call for truth and justice over the appalling war crimes which marked the awful end of the war in Sri Lanka. But what makes it particularly important is that it is told by a man who was there – a man who both cares about what happened, and understands how important it is that it never happens again. I urge everyone to support this project in whatever way they can.
