Why does his opinion in the Zimmerman/Martin case matter? Why is his opinion any more relevant than anyone else’s? Is he a lawyer? A self defense expert? A firearms expert? Forensic examiner? Does the fact that he is a famous actor give him some sort of expertise in any relevant topic? Does the fact that he is black give him some sort of insight that the rest of us do not possess? No, none of the above.
So why do I care what he thinks? Why should any of us care?
