I think deep down inside you know Oswald is guilty of the Tippit murder but you can't bring yourself to admit it lest your whole internal world come crashing down.
Actually, I couldn't care less if he did or didn't.
If you show me conclusive evidence of his guilt, I'll gladly consider him to be guilty.
But when evidence is misrepresented, ignored and dismissed out of hand, you have to give the suspect the benefit of the doubt.
