Yes, Oswald was totally innocent. The reason he left work shortly after the assassination and went to him rooming house was because he wanted to retrieve his revolver and hunt down the dirty bastards who killed JFK.
Like there's any evidence that he "retrieved his revolver" at the rooming house. WC apologists just love to state assumptions as facts.
He even carried extra bullets in case there were more than a couple of assassins.
You mean those "extra bullets" that were "found" in his pocket hours after he was arrested?
