Michael Brown family is 'profoundly disappointed'

A protester holds a sign in downtown Denver after a grand jury declined to bring murder charges against a Ferguson, Missouri police officer who killed unarmed teenager Michael Brown.

The family of Michael Brown, the unarmed black teen killed by a white police officer in Ferguson, Missouri in August, said on Monday they are "profoundly disappointed that the killer of our child" was not indicted.

The family, in a statement, urged protesters to avoid violence, remain peaceful and to channel their frustration into a campaign for body cameras to be worn by every police officer on a street beat in the United States.
