Wierd AL video White and Nerdy ever wonder why all the "gangsters" are Black only no other nationality?

Have you noticed in the Weird Al video “White and Nerdy” all the “gangsters” are Black? There are no Latino or Asian gangsters and no skin head gangsters either. Why would you suppose that? I know how it could be seen as though I don’t think that is the real reason but I will hold that until I heard from you and what YOU think the reason might be for the seeming one-side representation of a gangster.
