If you knew that [Sierra Leone's Revolutionary United Front] were coming, or if you even heard a rumour that the RUF were on their way, knowing that they cut the hands and feet off babies, you wouldn't hang around very long. And it worked -- it was very successful. It helped them clear the diamond fields, and they could dig diamonds to their heart's content. There are 1.5-million artisanal diamond diggers in Africa -- they produce about 16 per cent of the world's diamonds. So there's a good chance that 16 per cent of the diamonds in any store are part of that problem.
