There have been violent protests against the police in Ferguson, Missouri, for more than a week, since police shot and killed an unarmed black teenager named Michael Brown.
An African-American professor watching the situation sees a link between what’s happening in Missouri today and what happened in the state in the 1800s when it was at the center of the national debate and divide over slavery.
