LeBron James: Racism is hidden but alive

NBA superstar LeBron James says racism may appear hidden, but it is alive every single day in the US, and across the world.

The n-word was spray painted on to his Los Angeles home earlier this week.

Speaking at a San Francisco press conference ahead of a game, he also referenced Emmett Till, an African-American boy who was lynched in Mississippi in 1955. He said his mother decided to hold an open-casket funeral to show the world the hate he had suffered.
