But there is evidence that puts the first shot much earlier: just after z186 (e.g. Betzner) and just before z202 (Phil Willis) as the car approached the Thornton sign (z200, T.E.Moore) when JFK passed across Linda Willis’ sightline to the Stemmons sign (z195-z205-you can work that out based on her position in the zfilm). A first shot at z193 , which us where JFK begins changes to his head and hand positions, leaves 120 frames or 6.6 seconds to load, aim and fire two shots. JFK is already well into his reaction by z225.
The old laughable delayed reaction theory.
We are supposed to believe that JFK continued to calmly wave to the spectators to his right 9 frames, a half second, after being shot through the throat as seen here in Z202:

You could fill a small book with the ridiculous things Andrew Mason has convinced himself of in order to believe his cockamamie theory. It's a joke.
