What I realized, reading about people who do not realize the attackers are white, is that in high-profile cases the press usually prints (and re-prints ad nauseam) nice pictures of the “victims” smiling and playing with kittens, etc., right?
The fact that few know the attackers were white means they have not been showing those nice pictures of them.
But, no, they are not biased...
In the media's efforts to paint Rittenhouse as a white supremacist, it helps if the general public continues believing the men he killed were black.
