Sounds like BS to me.
Every one of these racial incidents turns out to a fraud.
Two recent fraudulent claims occurred. One was the Dean of a University who reported that she was harassed by police on a Sunday morning walk. The police car’s dashboard camera proved she was a liar.
Three days ago, Berkeley High School was a chaos because a racial rant was found on a library computer. When the culprit was apprehended, it was a black student.
