Tonight's show showing what would happen if you came upon two people arguing/fighting in the park. You didn't take the experiment the next step. Sure you showed a Caucasion man fighting with an African-American woman, an African-American man fighting with a Caucasion woman, but you didn't an African-American man fighting with an African-American woman.
Why didn't you show that? Could the reason be that in reality that most people especially Caucasions would have just walked by with out doing a thing. Had you shown that situation, It would have showed that race does matter. But it's the truth. I've seen it many times in public. Racism is still a sad truth.
