Both reasons were mentioned. They even stated that Liddy had not shot him the way they needed for him too. Another reason why that guy was brought in to change the appearance of the wounds. Either way, it just seemed far-fetched to me.
But, then again, so would having your own government kill your President.
Sadly, I think living through having a husband and brothers in Vietnam and the lies then its not hard for me to believe almost anything our government would do. Many family members and friends fighting in Nam said they wondered why we weren’t there to win the war. Then the lying media. So I again would believe editing and changing of film and pictures to match the narrative about the JFK murder.
