George Zimmerman's injuries were worse than first reported.
OK, and...? There's not one injury listed that is inconsistent with the story as it has unfolded: he stalked a young black man in a hoodie and murdered him. Did he expect that young man would do nothing while being threatened?
All it takes is one good punch in the nose to break the nose AND give two black eyes. Or a clumsy fat oaf to fall flat on his face running away from a murder. That would do it too.
