As a Movement for Black Lives Convening is set to take place this weekend in Cleveland, we discuss the case of Sandra Bland and many others who have died in the custody of law enforcement with the three founders of the Black Lives Matter movement. Patrisse Cullors is the director of Truth and Reinvestment at the Ella Baker Center for Human Rights in Oakland, California, and the founder of Dignity and Power Now, a grassroots organization in Los Angeles fighting for the dignity and power of incarcerated people and their families. Alicia Garza is special projects director for the National Domestic Workers Alliance. And Opal Tometi is executive director of the Black Alliance for Just Immigration.
