....while it was moving through frames 225 to the end of the Z film PROVES the Limo's parking lights are flashing in a disorganized manner. It was the one mistake the film altering agents forgot to take care of optically that is irrefutable. You remove frames and you break up the flashing parking light sequence. Nuff said.
In Assassination Science (1998) Part IV in the chapter The Case for Zapruder Film Tampering: The Blink Pattern pages 227-8 and 236-8 the authors state their case, that the .41 second blink rate established in the Hughes film is syncopated in the Zapruder
There are two elaborate charts on pages 237 and 238 "Pattern of Emergency Lights on Presidential Limousine" Z-133 through Z-238
In the author's analysis on page 236 the alleged rate of 18.3 fps required each side would remain on for 7.38 frames
If the film were not edited each of the emergency lights would blink at a constant rate "and a consistent pattern would be indicated by examining the appearance and location of the light pulses per each individual frame"
"Because Zapruder's camera only had two settings: 16 and 48 fps, and the blink rate was more than seven continuous flashes per side, the film in Zapruder's camera had to run at a faster setting than 18.3 fps"
Phil's footnote: In the article on page 224 is noted Zapruder claimed to be filming on 24 fps setting--yet authors say camera had only 16 and 48--and the calculation by someone is that it ran at 18.3--and a great many anomalies are ascribed to that wascally spwing
