In a Women’s History Month special, we speak with author, activist and scholar Angela Davis, professor emerita at the University of California, Santa Cruz. Her latest book is titled "Freedom Is a Constant Struggle: Ferguson, Palestine, and the Foundations of a Movement," a collection of essays, interviews and speeches that highlight the connections between struggles against state violence and oppression throughout history and around the world. "There were moments when things come together in such a way that new possibilities arrive," Davis says. "When the Ferguson protesters refused to go home after protesting for two or three days, when they insisted on continuing that protest, Palestinian activists in Palestine were the first to tweet solidarity and support for them. That opened up a whole new realm."
