U.S. vs China: The Battle for Bitcoin Mining Supremacy | WSJ

For years, Germany has been sourcing much of its coal from Colombia. But at what price? Colombians have been suffering from spiraling violence, while mining companies and European consumers profit. Time and again, coal-mining in Colombia has proven to result in severe human rights abuses and environmental degradation. People are forced from their land, lose property rights and suffer violence. El Samario, a former paramilitary soldier, talks about the countless murders he has carried out on behalf of international coal suppliers. The film sheds light on a dark part of Colombian life, and its links to Europe. It gives deep insights into the psyche of a contract killer, what lead him to commit murder and how he deals with his past. Can a murderer ever be forgiven? Can he forgive himself? ------------------------------------------------------------------ DW Documentary gives you knowledge beyond the headlines.
