This is a borderline question. I decided to ask in the politics forum because media outlets are nowadays an integral part of the political system.
In this video some people are shown holding some crystals and the journalist says that they might be diamonds. But it does not take an expert eye to understand that there is absolutely no chance. They cannot be diamonds. In the video they show people celebrating, but the locals know the mining business, they had to do with it for all their life. It's hardly credible to see so many people deceived by those stones, probably those interviewed were just actors pretending to celebrate.
Why would network with the reputation of the BBC release such a video? What do they expect to get from the impression it creates on the public?
