It bugs me that Alfonso is obviously Latino, played by a Negro
He drives into the black area and is asked "why do you have the magic ticket?" - would you seriously ask that of a black man?
Then he speaks spanish to his wife. He speaks spanish to his son. I haven't met many blacks who speak spanish. There are those who are black in Puerto Rico/Cuba, but they don't look/act like Denzel.
Plus the people he trusts with killing his partner are latino gang bangers.
Oh, and the name Alfonso is latino.
