This is what you run into with Cold Cases. Old People with Old Memories. It's the peripheral stuff laying dormant within a vivid memory that can provide a "dot" connecting several other "dots". Officer Luke Mooney discovered the sniper's nest, and was called to give WC Testimony pertaining to his sniper's nest discovery. The peripheral "DOTS" within his WC testimony/memory were that he remembered that the Huge Gates that open into the Elm St Ext were "Wide Open". And, on the other side of those Wide Open Huge Gates was a dock with a Door that opened directly into the TSBD 1st Floor. And, standing next to that same Door on the TSBD 1st Floor was the Stairwell. Yeah, THAT Stairwell. Why would 2 Huge Gates that by my estimation were each roughly 8' by 12' need to be "Wide Open"? "Wide Open" after the Assassination (per Mooney), "Wide Open during the assassination, (Couch Film), and "Wide Open" before the assassination, (Towner Film)? Why would 1 Man that already worked inside the TSBD and had access to the TSBD, need those 2 Huge Gates "Wide Open" before, during, and after the assassination? Oswald/One Man wouldn't. These "dots" all lead to a TSBD covert entrance and exit route used by More than 1 Man. These peripheral Memory "dots" have ALL been there for years. 61+ years.
