Oswald says he is a patsy

Well you couldn't have your patsy giving up any important information in a public trial now could you? This is when Jack Ruby went on to assassinate Oswald. It was another set up. There was no protection whatsoever. They needed to silence Oswald and their mission was accomplished.
Notice how Oswald claimed he never shot anyone and that he wanted legal representation. If he was supposedly a communist who wanted to kill our President then why wasn't he gloating about it? It is my opinion he was set up and he suffered the consequence. He never went on to tell his full story.
