New York's former mayor and Vancouver's mayor Gregor Robertson are pushing for climate change policies at the city level.
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.
Blair Kelley, who teaches history at North Carolina State University, finds parallels between Michael Brown and Dred Scott, a slave who sued for his freedom and ultimately lost his case in the U.S. Supreme Court in 1857.
The ruling basically said that African-Americans, free or slave, could not be American citizens, and therefore had no standing to sue in federal court.
Kelley discusses the Dred Scott Decision and the ongoing events in Ferguson with Here & Now’s Meghna Chakrabarti.
