A woman was knocked over by a police vehicle in Sacramento on Saturday, at a candlelight vigil for 22 year-old Stephon Clark who was shot and killed by local police officers on March 18. The sheriff's car careered into a demonstrator as it attempted to navigate through the crowd. The injured woman has since been treated in hospital. The rally was organised by former NBA star Matt Barnes... Еще, who vowed to unite his hometown to fight police brutality and the killing of black men by authorities. Clark's widow and two children were present during the rally. Offices were responding to reports of a man smashing car windows on the evening of March 18, when they shot at Clark 20 times in his grandmother's back garden. Authorities reportedly believed that Clark was armed but found he was actually just holding a mobile phone.
