I was showing the VP and VP Security Cars.
The "Lost Bullet" shows Euins in a location that he is not seen in in the Bell Film. And Donaldson says the limousine (stopped at Z334) is about where the first shot occurred. That doesn't even support Holland's theory.
Jerry,
You're making the very common mistake of conflating journalist Anne Donaldson with Patrician Ann Donaldson (maiden name: Patricia Ann
Lambert Lawrence).
Amos Euins was 14 years-old and quite short, and, according to him, he moved from near the curb on Houston over to the short pillar by the reflecting fountain (or whatever it is) as the limo was making the turn onto Elm Street, so it's no surprise that he hasn't been spotted in any of the films (yet).
Rhetorical question: When's the last time you watched
The Lost Bullet?
Factoid: If you watch a clear version of Mark Bell's film and/or Tina Towner's film in slow-motion, you can spot Lambert and her friend Lupe Whittaker (both basically dressed in black) and tall, dressed-in-white Stetson Man (all three of whom are very visible in the Wiegman film), standing on the "island," or maybe in the street just off the tip of the "island," to the right of the TSBD's entrance (from Bell's and Towner's points-of-view).
