Civil rights activist, the Reverend Al Sharpton, has called for calm and for police transparency in Ferguson, Missouri, after the shooting of an unarmed black teenager by police.
The death on Saturday of Michael Brown, 18, has sparked two nights of unrest.
Mr Sharpton described the rioting and looting that followed his killing as a betrayal of the teenager.
