August 4 marks ten years since Mark Duggan was fatally shot by the police and what followed were some of the most violent riots the Britain has seen for decades. It wasn’t just his killing that was the cause of these riots. It was a range of social issues and disputes that were ignited by his death. In this episode, we return to a feature brought to you last year - 'The racial killings that shamed two nations' - where Noel Phillips asked what stills needs to be done to resolve tensions between police and black communities as he looked at the deaths of two men, George Floyd and Stephen Lawrence, nearly 30 years apart and on different continents.
