Witnesses to smelling gunpowder at street level:
Ralph Yarborough was in the car two cars behind the Presidents car and said he smelled gunpowder. He is a war veteran with more than 50 years experience with fire arms. WC Vol VII, pg 439
I have read that affidavit several times before and fail to see where he said anything about 'gunpowder', 'smoke', or 'smelling' anything.
In fact the senator gave in to 'three shots' and ' they were coming from high back at the building'.
Something Mrs Cabell was not supposed to say...
Mr. HUBERT. And it was about that time that you observed the odor?
Mr. CABELL. Of gunpowder.
Mr. HUBERT. That was when your car at least had come to a standstill?
Mr. CABELL. Every car in the motorcade had come to a standstill.
