I disagree whole heartedly with your assessment Lance. JFK, Jackie, and the limo were in a significantly different direction from where Linda Willis is pointing. All you have to do is follow the panning motion of Croft and his camera to know where the limo is. If that seems too difficult, take a look at the full frame video that actually shows the limo and its occupants. Linda’s pointing motion seems to me to be a very quick instinctive reaction to the sound of the first shot. Unless she happened to look specifically at the sniper’s nest window and saw LHO aiming his rifle, she might not even remember this reaction at all. My opinion, yours may vary.
Well, no, you don't disagree with my assessment - you disagree with Linda's assessment. Linda says she was waving, Linda says she thought the first shot was a firecracker, Linda says she never even looked at the Depository. Because Linda's own recollection is inconsitent with whatever point you're making, you attribute to Linda an "instinctive" reaction of which she was wholly unaware. The woman in front is clearly waving and clearly not looking up at the sixth floor, but Linda "instinctively" is. Ho-kay, on it goes.
14-year-old Linda told the WC she was directly across from the Stemmons sign when she heard the first shot, which she first thought was a firecracker but realized it was a shot when JFK's hands went to his throat. As I recall, this is also exactly when Gloria Calvery and her two companions said the first shot occurred.
