This reminds me of an incident a few yeas back when a black woman was the EEO representative in a college faculty. She suspended a hangman's noose over her doorway and called the police. It made news headlines and later the security closed circuit TV cameras revealed the truth.
My favorite one was when a black family’s house in upscale Marin county, CA was torched. Someone spray painted “KKK” and “Blacks get out!” next to the house. Eventually they arrested and convicted the owner for burning it down for the insurance money. When they asked the arson investigator what made him suspicious initially he said, “Since when does the KKK say “Blacks”?”
