Under what rational interpretation of self-defense could Zimmerman’s actions qualify? Zimmerman chased Martin down. Zimmerman tackled Martin after Martin demanded to know why Zimmerman was following him. Martin screamed for help. And Zimmerman shot him. Even if Martin fought back, how could such a thing — a quite reasonable response, it should be noted to being attacked by a total stranger — justify pulling a gun, pulling the trigger and shooting the person who was acting in self-defense against you? To those who accept Zimmerman’s claim of self-defense, let us ask a simple question: would you be so willing to buy that argument if a black person were to chase down a white person in a mostly black neighborhood, and then upon catching him, end his life when the white person resisted being pummeled? You know full well the answer. We all do.
