She knows what it means, dumbass. I get it -- you don't think highly of black people.
But I could very well have said those exact words. "What do you mean, chain of command" is a way of saying, "there is no chain of command, are you fucking kidding me". It's a more polite way of saying that. If I didn't say exactly what she said, I might have responded more like, "what are you talking about, a chain of command in this pigshit seat-of-the-pants, racist administration where one is more evil than the next? They don't know how to tie their goddamn shoes, let alone run a police department."
So I think you should apologize for that load of racist drivel.
