Lawmaker: If Wilson is not charged in Ferguson, a ‘simmering anger’ will surely materialize

(CNN) – Will Ferguson erupt in protest if the grand jury does not charge Officer Darren Wilson in the shooting death of Michael Brown?

Once a decision is reached, law enforcement will be given 48 hours notice before a public announcement is made. Officials in Missouri are hoping for calm, but bracing for violence if Wilson is not indicted.

Three people were arrested Thursday night after clashing with police.

Rep. Emanuel Cleaver, D-Missouri has been very vocal about the killing of Brown and in a recent op-ed wrote if Wilson is not charged "a simmering anger among African-Americans will surely materialize."

But does he see any possibility that Wilson feared for his life? Check out our interview with Rep. Cleaver in the video above.
