That lightly colored car IS parked tight to the island. The Elm St Extension is only 2 lanes wide. In the photo that Charles posted, I can see the (R) side of this lightly colored car up to/including the (R) front passenger window. This is the same car we see on the tail end of the Hughes film. The Hughes film shows the car parked to the (L) of the "NO PARKING" sign. That sign is attached to the Street Light Pole. It is also the same car we see on YOU TUBE - "Manhunt: The Search for JFK's Killer (Full Episode) | JFK: One Day In America" by - National Geographic. At the 8:56 point, we see this same light colored car parked/hugging the Island side of the Elm St Extension. This very same car is on numerous Films and Photos taken that day. Whether it is Roughly 20 seconds after the kill shot, or 3+ hours after the kill shot, this car is sitting in the exact same spot. (L) of the 2 poles.
Dear Sonderführer Storing,
If I'm understanding you correctly (always a risky proposition), it sounds as though you're not seeing the rear end of the 1958 Pontiac Bonneville "Getaway Car" that's parked "tight against the near curb" in the photo that Charles posted because it (the Getaway Car)
overlaps the front part of a light-colored car that's facing from left-to-right on the other side of Elm Street Extension.
From the perspective of the photographer the hard-to-see rear-end of your 1958 Pontiac Bonneville "Getaway Car" (Although we can see its bumper) begins about a foot to the right of a pole on the "island," and most of it is obscured by the husky "cop" in the foreground.
Question: What vehicle on the other side of Elm Street Extension is that on the right side of the husky "cop's" right shoulder?
