Michael Brown killing: Violence turns to peace

A change in police tactics in the aftermath of the death of US teenager Michael Brown in Missouri has turned four days of violence into peace.

The tension in Ferguson had been sparked by the shooting of Brown, 18, on Saturday afternoon.

Details about the incident have been disputed but eyewitnesses said the unarmed teenager had his arms raised when he was shot multiple times by a police officer.

Captain Ronald Johnson of the Missouri Highway Patrol, an African-American who grew up nearby, was named as the new head of the operation.
