Protesters decrying the fatal police shooting of 22-year-old Stephon Clark swarmed Sacramento's streets, council meetings and stadiums, forming a human chain to block fans from attending a professional basketball game at the Golden 1 Center. They also gathered at Sacramento City Hall and flooded Interstate 5. Clark, a black man, was unarmed when he was fatally shot Sunday by police, who feared he had a gun. However, investigators found only a cellphone. A council meeting held to address the concerns of Sacramento residents was postponed after protestors spilled into the room, with one arrested for assaulting an officer.
