Grieving father: I know what you're thinking. My son wasn't in any gang. He was a good kid. Halstead: Okay. Is that what the police think too? Grieving father: The police? The police don't think anything. They never did a damn thing about it. Halstead: Okay, I doubt that. Come on. Grieving father: No, no, no. Don't tell me. Black kid lying in the street, step over him, move on. All the same to them.
