The Charlottesville, Va., City Council voted to drape two Confederate statues in black fabric during a chaotic meeting packed with irate residents who screamed and cursed at councilors over the city’s response to a white nationalist rally.

The anger at Monday night’s meeting, during which three people were arrested, forced the council to abandon its agenda and focus instead on the tragedy. Covering the statues is intended to signal the city’s mourning for Charlottesville resident Heather Heyer, who was killed when a car slammed into a crowd protesting the rally.

“I think what you saw last night was a traumatized community beginning the process of catharsis,” Mayor Mike Signer told The Associated Press on Tuesday.

The council meeting was the first since the “Unite the Right” event, which was believed to be the largest gathering of white nationalists in a decade. The demonstrators arrived in Charlottesville partly to protest the city council’s vote to remove a statue of Confederate Gen. Robert E. Lee.

That removal is in the midst of a legal challenge. A state law passed in 1998 forbids local governments from removing, damaging or defacing war monuments, but there is legal ambiguity about whether that applies to statues such as the Lee monument, which was erected before the law was passed. A judge has issued an injunction preventing the city from removing the Lee statue while the lawsuit plays out.

Signer said Tuesday that city staff had begun working to find a way to cover the large statues with a material that can withstand the elements. The council believes doing so would not violate the state law, he said.

At the meeting, many speakers directed their anger at Signer. They expressed frustration that city leaders had granted a permit for the rally and criticized police for allowing the two sides to clash violently before the rally even started. That fighting went on largely uninterrupted by authorities, until the event was declared an unlawful assembly and the crowd was forced to disperse.

“Why did you think that you could walk in here and do business as usual after what happened on the 12th?” City Council candidate and community activist Nikuyah Walker said.

The mayor tried to restore order, but as tensions escalated, the meeting was temporarily suspended.
