Outrage over the shooting led to days of protests in Ferguson and a heated debate over whether Brown's race played a role in his death.

Brown was black, like two-thirds of his neighbors in Ferguson. Wilson is white, like most of the city's police department.

The grand jury, which meets in secrecy, consists of nine white people (six men and three women) and three black people (two women and a man), court officials have said.
