It was thirty years ago, May 1985, when Bishop Tutu spoke so eloquently at the Greek Theater, I was there. When students took over Sproul Plaza, leading to UC Berkeley’s divestment of $1.7 billion from South Africa, I was there. When Nelson Mandela came to the Oakland Coliseum in 1990 to thank us after decades in South African jails, I was there. Divestment movements and boycotts can and do work.
