It's been a long time since I've seen anyone bring up the Badgeman claim. I didn't realize Gary Mack was the originator of the claim. He turned the Moorman photo into a Rorschach test. He blew up a 1/4" square and then added color for effect. Apparently Badgeman and Gordon Arnold were both about 9 feet tall.
Your admission above is why I continue Urging you to expand your JFK Assassination Foundational Knowledge. Knowing that Gary Mack and Jack White conjured "Badge Man" from the Moorman Photo is "JFK Assassination 101". And, your Not knowing this also means you have Not watched, "The Men Who Killed Kennedy" (1988), which once again is, "JFK Assassination 101".
After Gordon Arnold told his story on, "The Men Who Killed Kennedy", he then did a Q/A for the Sixth Floor Museum. This Q/A was very good and detailed. Arnold said they were pushing dirt around between the picket fence and the short wall running down from Zapruder. Arnold said he stood atop a mound to do his filming. He said when a shot whizzed over his (L) shoulder, he dove and rolled. This had been part of his military training and his diving and rolling is corroborated by U.S. Senator Yarborough. Yarborough was riding inside the LBJ Convertible on 11/22/63. This Yarborough corroboration is part of, "The Men Who Killed Kennedy". Arnold also said during his 6th Floor Q/A that the cop kicking him around was wearing colored glasses. Shooter's glasses.
