All you gotta do is prove this 17+ foot long car is on the Wiegman Film. It's NOT there! This "getaway" car rolling down the Elm St Extension as shots were being fired, and then being deserted in a "NO PARKING At Any Time" zone for 3+ Hrs, just outside of the "wide open" Huge Gates, should have been discovered a long, long, time ago. The JFK Assassination Researchers, (past and present), Never pay any attention to the Elm St Extension.
The same goes for the Research Community totally ignoring the Railroad Yard. This is why we also have the erroneous ID of Officer Haygood being filmed inside the railroad yard on the Darnell/Martin Films. That ain't Officer Haygood with Officer Harkness back inside the railroad yard. The timelines of Haygood and Harkness make it physically impossible for them to be filmed together, before 12:35, back inside the railroad yard on the Darnell/Martin Films. 12:35 being when Haygood made his documented radio transmission from his motorcycle parked at the Elm St Curb. And the "lost" Darnell Film snippet that I recently discovered on a "The JFK Theorist" You Tube posting further proves this.
