Maybe the black guy was gay? Maybe he didn't see her? Maybe he was drunk or stoned? More details would be much appreciated.
US police forces arrest white guys everyday.
If they had a picture of the guy who shot her, they wouldn't be looking for him. Also, it's true that the US Police forces arrest white guys every day, but none of the arrests occur because the guys are white.
I'm talking of a picture of the victim, or the crime scene. Is this a troll or what?
Hey, nobody's arrested because of color. There are plenty of colored police officers everywhere in the US.
