Guess what? When was the first Altgens photo taken? Frame 225 of Zapruder film? Hell no! The Altgens photo shows the motorcade during the huge missing segment of the Zapruder film, between frames 132 to 133--which also is when the the first two shots are fired (one hits JFK in back, the other goes through the JFK limo windshield) Greer has brought the limo to a complete STOP which is why the DPD motorcycle cops are looking back because they are going to overtake their orders to not get past the JFK limo’s rear wheel. Comparing the position of the motorcade middle in the photo, its alongside the TSBD entrance and cannot be aligned with Zapruder frames 225 or 255 as some have suggested because the footage we should be seeing is missing!!! When the Zapruder film shows the motorcade suddenly at frame 133 it is far beyond the TSBD doorway!!
