Buying a Rolex is supposed to be a happy occasion. Especially for the Milwaukee Bucks’ John Henson. He’s 24. He’s a baller. He has some cash to burn. And it would have been his first Rolex. All this guy wanted was to make a big purchase and for his friends to be there to join in the revelry. But as the newly released 911 tape of the incident demonstrates, because Henson is black, all fun must end with the police being called.
