“Outside agitator.”

These words were spoken by Mississippi Governor Ross Barnett when asked about the Freedom Summer voting registration drive in 1964. They were also uttered by Alabama Governor George Wallace when he was asked about the protests in his state’s largest city, ignobly labeled “Bombingham.”

Bull Connor referred to Martin Luther King Jr as one, even though his church was in the state capital, Montgomery. These two words were also uttered by Thomas Jackson, the police chief in Ferguson, as he tried to describe why his mostly-white police force could not stop the protests occurring in the nearly 70 percent black city he was charged with patrolling.
