The official story has Oswald exiting the front entrance about 3 minutes after the shots. At a time Bill Shelley was no where near the front entrance. Yet dumb'ass Oswald once again knowingly uses employees who were not in a position to support his alibi. Shelley was at City Hall that afternoon until 5pm. Oswald was seen by Lovelady and Williams, the latter rode in the same car as Shelley to HQ. There are images of Oswald walking right passed Lovelady.
