Ambush Phase II Forward Observers: was the Umbrella Man’s snappy dressing assistant in direct radio contact with Kellerman to stop the limo (umbrella open?) and signal for frontal shooters to fire (arm raised?) or vise-a-versa? A risky frontal shot reveals a multi-shooter conspiracy---only taken to insure JFK is finished off in event earlier shots before the Stemmons sign (Phase I) had failed to hit JFK’s head.
THE ASSISTANT: Arm raised; “STOP THE CAR, GREER!….”
TUM: Open Umbrella; means fire the frontal shot, JFK’s head still intact; Closed Umbrella, don’t frontal shoot
