About 300 protesters, including former US Army soldier Chelsea Manning, participated in a peaceful march to the campus on Saturday. On September 24, Yiannopoulos, Cernovich and Geller arrived outside Sproul Hall and Yiannopoulos spoke very briefly without a sound system and sang the US national anthem. Hundreds of protesters and supporters surrounded the police barricades that were erected that morning around Sproul Plaza. Attendees were permitted into the plaza only after passing through a single metal detector; approximately 150 people saw Yiannopoulos speak, while hundreds more waited in line.
