There is a video of a white police officer shooting dead a white guy crawling toward the police as instructed and he made the mistake of trying to pull his pants up. That police didn't get convicted, but should've. So, it's not really racial. There are many black police officers. There is even a video of several black police officers beating a black guy to death. There were black police officers around Floyd too.
