In Who’s Your Source?, host Radzi Chinyanganya examines how reporters get their information from different sources and ensure their accuracy. For example, BBC journalists exposed a network of hidden detention centers in Western China where Muslims were detained without a trial. The Chinese government was working hard to keep this story hidden by closely monitoring, and even detaining, journalists. Reporters used satellites to investigate, and they also interviewed Muslims in Turkey who claimed to have been in the detention compounds. They looked for consistency and overlap in their stories. Verifying information from multiple sources helps a journalist assess a story and tell it accurately. This video is excerpted from BBC’s My World, a program created for teenagers eager to learn more about the important stories shaping our world.
