Protesters storm City Hall in St. Louis

Several people protesting the a grand jury decision not to indict a police officer in the shooting death of an unarmed black 18-year-old stormed into City Hall in St. Louis Wednesday, leading police to lock down the building and call in more than 100 additional officers, The Associated Press reported.

Those who got inside City Hall were part of a group of about 200 protesters who marched and held a mock trial of Darren Wilson, the white police officer who shot Michael Brown during a confrontation in Ferguson, a St. Louis suburb.

At least two people were arrested after the City Hall incident, in which protesters shouted “Shame, shame” while rushing into the building.

The racially charged case has stoked passions nationwide, sparking debates over the relations between black communities and law enforcement. Since the grand jury’s decision was announced Monday night, protesters in cities throughout the U.S. have rallied behind the refrain “hands up, don’t shoot,” and drawn attention to other police killings.
