Hundreds of demonstrators are marching through downtown San Francisco Saturday, to protest last month's police shooting that took the life of Mario Woods.
They gathered at Union Square at 11 a.m., and marched to Super Bowl City along the Embarcadero.
KTVU Fox 2 had crews on the ground, and in the air recording the protest.
Demonstrators went down Market Street, yelling for Police Chief Greg Suhr to get fired.
Their chant was "For justice, Mario Woods" and "Fire Chief Suhr."
Protesters were followed by a group of San Francisco Police officers in riot gear.
So far, there were brief standoffs between police and protesters, but the march has not turned violent.
Organizers have held a series of protests in the Bay Area, following the December 2 shooting.
Protesters said police officers fired some 20 shots at Woods. But officers claim he was a stabbing suspect, who confonted them armed with a knife.
Officers said he ignored repeated orders to drop the knife.
The family of the 26-year-old Woods, has filed a wrongful death lawsuit against the police department and the city of San Francisco.
