Ferguson protests: 16 arrests in latest demonstrations Last Updated Nov 29, 2014 8:42 AM EST FERGUSON, Mo. - Disrupting commerce, transit and traffic became focal points for demonstrators across the country days after the announcement that a grand jury in Ferguson, Missouri declined to indict the police officer who fatally shot 18-year-old Michael Brown. As Small Business Saturday approached, numerous storefronts in the Ferguson area had their windows covered with plywood with messages painted across many of them letting neighbors know that the shops are still open. Demonstrators temporarily shut down three large malls in suburban St. Louis on Black Friday, one of the busiest shopping days of the year, and then marched in front of the Ferguson police department to protest the grand jury's decision. Several stores lowered their security doors or locked entrances as at least 200 protesters sprawled onto the floor while chanting, "Stop shopping and join the movement," at the Galleria mall in Richmond Heights a few miles south of Ferguson, Missouri, where Officer Darren Wilson fatally shot Brown, who was unarmed, in August.

And several dozen demonstrators led to a temporary closure of the Chesterfield Mall. Later Friday night, a group of about up to 75 protesters marched down West Florissant Avenue Florissant in front of the city's police and fire departments chanting, blocking traffic and stopping in front of some businesses. A number were apparently from an out-of-town communist group holding up a sign that read "Progressive Labor Party," reports CBS News producer Jonathan Blakely. Wearing gas masks and goggles, despite the fact that no tear gas was used, they chanted phrases such as: Who do we want? Darren Wilson! How do we want him? Dead! The only solution is a communist revolution! Turn your guns around and shoot the bosses down! Sixteen people were arrested, according to Officer Shawn McGuire, spokesperson for the St. Louis County Police Department. Charges would include peace disturbance and impeding the flow of traffic, and two people would be charged with resisting arrest and one with assault. All 16 people arrested were from out of town, including nine from New York. One officer injury was reported. Elsewhere on Friday, protests in Chicago, New York, Seattle and northern California - where protesters chained themselves to trains - were among the largest in the country on Black Friday. In Oakland, more than a dozen people were arrested after about 125 protesters wearing T-shirts that read "Black Lives Matter" interrupted train service from Oakland to San Francisco, with some chaining themselves to trains. Later in San Francisco, a march by hundreds turned ugly as protesters smashed windows and hurled bottles and other objects at police, leaving two officers injured. Police respond by making arrests but have not said how many. Dozens of people in Seattle blocked streets, and police said some protesters also apparently chained doors shut at the nearby Pacific Place shopping center. Missouri Gov. Jay Nixon on Friday announced that he will call a special session of the General Assembly to provide funding for public safety efforts related to protests. A news release from his office said that due to the increased presence of the State Highway Patrol and the Missouri National Guard in the region, the state's financial obligations for emergency duties are on track to exceed what had been appropriated.
