Rogue Miners?!?!

On Monday I heard a story about Chinese miners mining illegally in the Western Region. I later read the full details in The Daily Graphic. Essentially some Chinese citizens have descended upon Ghana equipped with various mining tools and are extracting precious minerals. I am both shocked and incensed. Apparently this has been going on for more than a year and nothing has been done to stop it. This mining activity has heavily polluted the River Ankobra which is used for drinking water by people in that area. I am at a loss for words. There is a Mining Act in Ghana (the Minerals and Mining Act, 2006 (Act 703)) and so far as reported everything these miners have done is in violation of that Act and yet nothing has been done to stop them. How can the government stand by and allow this to occur? And as for the miners, I'm astounded by their gall and audacity. Can you imagine setting up shop in a foreign country and just pillaging their resources? Why did they think they could do that and why are we allowing them to get away with it?
