State of emergency for Charlotte as unrest over police shooting continues per BBC News who don't report an inconvenient fact

This BBC report http://www.bbc.co.uk/news/world-us-canada-37436676 on the rioting in Charlotte which has followed the shooting of an African American misses one key piece of information that the Black Lives Matter and their supporters at the BBC might find inconvenient to their claims of racism in the police force and elsewhere in the USA. 

It is reported by Breitbart and others that the policeman who shot Keith Lamont Scott was also an African American, Brentley Vinson. Why would the BBC not report that?
