In 2016, vandals in Loudoun County, Virginia (near Washington, DC), defaced the one-room schoolhouse that had been the Ashburn Colored School, built in 1892. The first article below is the Washington Post news article, written when information was somewhat incomplete. The second, written several years later, is a BBC look at the result.
Note: For historical reasons, Virginia, like Pennsylvania, Massachusetts, and Kentucky, always refers to itself as a "Commonwealth." There's no real legal difference between a commonwealth and a state in US laws.
This is the original 2016 Washington Post news article about the vandalism: Historic black school defaced with 'white power' and Nazi graffiti.
Graffiti punished by reading - 'It worked!' says prosecutor by Emma Jane Kirby.
