As unrest rocked Ferguson once again -- with some businesses going up in flames -- a far more peaceful protest was unfolding Monday night elsewhere in the St. Louis area.
A crowd of at least several dozen demonstrators chanting, "This is what democracy looks like!" blocked traffic going both ways on Interstate 44, near the St. Louis neighborhood of Shaw.
The protesters gathered after the announcement that Ferguson Police Officer Darren Wilson would not be indicted in the shooting death of Michael Brown.
Police have warned that demonstrators on the interstate could face arrest but have not closed in, according to live-stream footage from the scene. A few vehicles have been blocked in by police and demonstrators.
Several demonstrators sat across the road staring at the police line in the distance.
The Shaw neighborhood became a flashpoint for demonstrations after an off-duty St. Louis police officer shot and killed Vonderrit Myers Jr., in October. Police said Myers had a gun and fired at the officer, who shot 17 rounds in return.
