Good catch. We have the film of JFK's Limousine that L'Hoste took. He was in front of the restaurant where Helen Markham was scheduled to work a bit later that afternoon. Did L'Hoste take a ride to get to Trade Mart and stopped at Dealey Plaza within 90 seconds? On foot it would hve been impossible to get there in 90 seconds. L'Hoste did not testify.
What about if we add the time it took for the limo to get from in front of the restaurant to Elm Street to the equation? I believe one of the coworkers of LHO (maybe Givens) testified he watched the motorcade on Main Street, then walked back to Elm Street, then heard the shots.
