This reminds me of the knock out game. When that was creeping into the news the media ran interference and said it's not a real thing and it's been made up by racists to make blacks look bad because no black has ever hurt someone in the history of the world. Then it got depicted in TV shows and movies but always being done by white guys. So now these happen attacks happen and at least the news acknowledges they occur, but they're still doing the shtick of saying it's only white people.
