During the concert, the band's frontman Zach de la Rocha said to the crowd, "brothers and sisters, our democracy has been hijacked," and later also shouted "we have a right to oppose these motherfuckers!" After the performance, a small group of attendees congregated at the point in the protest area closest to the DNC, facing the police officers. Reports of what activity they engaged in vary, the most extreme being reports of throwing glass, concrete and water bottles filled with "noxious agents," spraying ammonia on police and slingshotting rocks and steel balls. However, milder reports also arose, one only mentioning "tossing rocks." The police soon after declared the gathering an unlawful assembly, switch off the electrical supply, interrupting performing band Ozomatli, and informed the protestors that they had 15 minutes to disperse on pain of arrest. Some of the protesters remained, however, including two young men who climbed the fence and waved black flags, who were subsequently shot in the face with pepper spray. Police then forcibly dispersed the crowd, using tear gas, pepper spray and rubber bullets. At least six people were arrested in the incident.
