The company, the Sierra Leone Selection Trust had a lease area and it included kimberlite pipes, and I can explain something about how diamonds are mined if you'd like, but it included some deep shaft mines as well as alluvial diamond mining. Alluvial diamond mining is basically diamonds - you're mining diamonds that are very close to the surface of the earth. These alluvial diamonds can be mined in many cases - well, almost a hundred per cent of the time they can be mined by individuals with little more than a shovel and a sieve. The diamonds are very close to the surface. Obviously the Selection Trust didn't want to lose its diamonds to illicit diggers so the police - the purpose of having a large police force was to try and round up people who were in the district illegally and also people who were there legally but digging illegally.
