Four times Toni Foster said, "The car stopped!"

[Barry Pollard]

People said "firecrackers", "gunfire", "explosions" but when we find them in the evidence they are usually smiling or waving through it.
Greer and Kellerman react only to JBC screaming IMHO. Only one bullet has entered the vehicle so far and it stopped inside that same man.
So Bill is looking to see what the trouble is or, he was actually psycho.
Again an opinion but to drive from Love Field knowing your heading into an ambush, in an open top vehicle, with no protection takes some doing and summoning up a cheesy smile as you turn onto Elm, that's some bulls, with me driving the limo would be wrecked, fenders hanging off, occupants all distressed...
Assassin used the opportunity of the limo slowing to register the best shot, a gift from god after a nervey start.
Why would the conspirators involve the driver unless the USSS were themselves at the very heart of it?

PS. Greer never admitted hitting the brakes IIRC.

Why didn't Greer stop the limo for the first shot? Did he wait until Kennedy was shot until he decided to stop/slow down the limo ? Was he waiting for the "stickman" in the infield area to signal him  ? Inquiring kook bags need answers. 

[Bill Chapman]

I've read that he thought there might have been a motorcycle backfire or that he had a tire blowout and tapped the brakes...
I really tend to think that is his cover... He is looking steady toward JFK up until the fatal moment...

[Excerpt]

Secret Service procedures in place at the time did not allow Greer to take action without orders from senior agent Roy Kellerman, who sat to Greer's right. Kellerman has stated that he shouted, "Let's get out of line, we've been hit," but that Greer apparently turned to look at Kennedy, initiating a fatal delay, before accelerating the car out of the danger zone.[6] As Roy Kellerman told author William Manchester, "Greer then looked in the back of the car. Maybe he didn't believe me."[7]

Seems to me Greer's foot pressure on the gas pedal might have relaxed somewhat as he twisted around to look behind. And I don't know why anyone would sign on to a plan that would require him to ride in an open-topped vehicle which would be the target of multiple snipers, world class or not.

Great plan: Get the driver to conspire, at the very real risk of having him getting last-minute cold feet and aborting the mission 

Let's see a Greer backstory that would, plausibly, point to him as a candidate for such lunacy.

[Barry Pollard]

Does the grimace into the sun caught by dad turn into cheesy grin for Tina? I still think so.

But I guess with JBC looking so worried in 95% of the images the same logic would suggest he knew, or at least he was worried about something, personally I have no trouble with the latter.

Here are some kook bag answers for you Proctoboy.  Let's begin with the most likely premise, that this was a conspiracy. All but the LNers think Oswald acted alone. The rest of the world thinks he was a patsy. The conspirators empowered you LNer shills to be the DWC (Defenders of the Warren Commission). Your mission was to extend the debate just long enough for all involved to croak. So far, so good, your efforts have managed to provide token opposition and cast doubt on the conspiracy to almost call this one a 100% successful coup d'etat. Only GHWB remains to stick a fork in this one. Once all the conspirators are dead and they get off scott-free, 100% win! But that's like a no-hitter going into the 9th. Otherwise, the conspirators won this one clean when the foxes formed the WC hen house.

Why didn't Greer stop the limo for the first shot?

Where/when was that?

• Then ask Greer why he stopped the limo when turning onto Elm?
• Then ask yourself why Oswald didn't take a shot with JFK 60 feet directly in front of him at a dead stop?
• Then ask yourself why the FBI cut out that section of the Z film?

Did he wait until Kennedy was shot until he decided to stop/slow down the limo ?

No, Greer knew the exact place on Elm to slow the limo down to, the Turkey Shoot Point (TSP). Whether Greer knew why he was slowing the limo down is unknown. Same as the SS agent that got called off of the back of the limo and responded with WTF open arms. Obviously, some SS agents were in on it and some weren't. I doubt that any of them knew how deep the rabbit hole went, they were just pawns with minimal need to know info re the coup. Once it all went down, they were committed to STFU.

So why do I claim the Z film was edited? Because there are obvious splice points in the film and Zapruder did not recall taking his finger off the camera trigger as the motorcade turned onto Elm. But the most important aspect is that the Z film is missing the "1st Overexposure Frame" when you stop then start a film camera. The Z film that we see is clearly a copy and the turn onto Elm has been erased. So what happened at the turn onto Elm and why didn't Oswald take the 1st shot?

JFK wasn't killed until he reached the TSP so the conspirators could paint the narrative that Oswald was shooting at him from the TSBD. The TSP was designed to allow the snipers full access to JFK and if you timed it right, you could make 3 or 4 shots sound like 1, which was the case. One of those shots was from the knoll and it was frangible. This shot blew out a gaping hole in the right temple of JFK. A simultaneous shot from the overpass likely created the hole in the back of JFK's head (which the medicos and Z film editors tried their darndest to erase from the records).

With so much other evidence pointing to Oswald being a patsy, why do you cling to the LN narrative, Proctoboy?

Yet, 5, F-I-V-E governmental studies say Oswald did it (wikipedia entry for Oswald), I guess all of the studies are tainted and they are all on the take.

One can say the Lone Nut or Warren Report single bullet believers are in the minority but how does it shake out when the conspiracies one puts out then are:

1. CIA, rogue government elements
2. Mafia/Organized Crime
3. Castro's Cuba....
4. Other theories

Then, the percentages may well come to be similar to those who believe in the LN.
