The Parkland Staff are probably telling the truth, and the "shallow chest cut" story from the autopsy pathologists was a ploy to cover up the full extent of the damage to the lungs and interior body. This also makes me wonder if the autopsy pathologists were literally acting and performing a charade in front of the morgue witnesses when they initially reported the back wound could only be probed a fraction of an inch. Shallow chest tubes, shallow back wound, shallow trustworthiness.
