I am fully aware of what is legal and what is not. How do you know DC is not racist because it appears he has racist behavior and tendency

No just ones who go outside of their duties. Like choke holds, shooting unarmed suspects, knees on the neck/shoulders, punching, kicking, slapping, phone books, and racial slurs. They don't necessarily have to be white. DC is a racist!

What's your proof he is not a racist?

I love my Racine family
