“You have never been anywhere in Africa have you.”
Yeah, sure, Sunshine, go live in Africa and tell us what a jewel it is. It’s a sh*thole, the entire continent. They don’t report their murder rates so that crap is unreliable.
Since you wanted to compare murder rates within cities, you might want to also review that those murders are committed by Africans.
