What would the purpose of that be? Do you think that is going to satisfy the crazies? The findings of the original autopsy didn't satisfy them? The concurrence of the FPP didn't satisfy them? Why would anyone believe another bite of the apple would satisfy them? If the body was reexamined and the same conclusion was reached, the crazies would just cry foul again and invent more excuses not to trust the process.

The FBI agent of the Dallas office, quote in the news article in the OP, at the time of Gov. Connolly's death completely disagrees with you.

How could Hickey have not heard a nearby high-powered rifle shot at either "Z-124" or your beloved Z-148?

I've always heard, "Actions speak louder than words."

Regardless of the fact that he didn't remember doing it, why do you think Hickey started leaning over to look at the pavement in Z-146, even before your beloved jiggle-proved / misinterpreted-JBC-headturn-proved Z-148?

To answer your last question first, I have no idea what Hickey was doing because he never mentioned it in his report. He said he looked to his right rear upon hearing the first shot. I don't know how you tie that to his action of looking down to his left. That seems to be quite a stretch.

As for not hearing the first shot, or at least not recognizing it for what it was, that is not at all hard to understand when you take into account he was being straddled by four motorcycles, two to each side of him, and those motorcycles would be accelerating out of a 110 degree turn in order to keep pace with the limos. All four officers would have been on their throttles which would have created a very loud racket, maybe not enough to completely drown out the sound of the shot but certainly enough to muffle the noise to the point it wouldn't have sounded like a gun shot. If you have a better explanation for why Clint Hill and Jackie only remembered hearing two shots, I'd love to hear it.

Clint Hill's report also indicated the first shot he heard was the one that hit JFK in the back:

"The motorcade made a right hand turn onto Elm Street. I was on the forward portion of the left running board of the follow-up car. The motorcade made a left hand turn from Elm Street toward an underpass. We were traveling about 12 to 15 miles per hour. On the left hand side was a grass area with a few people scattered along it observing the motorcade passing, and I was visually scanning these people when I heard a noise similar to a firecracker. The sound came from my right rear and I immediately moved my head in that direction. In so doing, my eyes had to cross the Presidential automobile and I saw the President hunch forward and then slump to his left. I jumped from the Follow-up car and ran toward the Presidential automobile. I heard a second firecracker type noise but it had a different sound-- like the sound of shooting a revolver into something hard. I saw the President slump more toward his left."

Hill apparently conflated Elm St. with Houston St. in his report. Clint Hill's WC testimony tells much the same story if you want to read it:

If Clint Hill didn't hear the first shot, why do you find it hard to believe Hickey didn't either.

Dan is ignoring that those two are exactly where they are supposed to be according to testimony after leaving the steps...

There's no point getting bogged down with everything that is wrong with this post but this last observation needs addressing.
Apparently it's me, ands not Brian, who is ignoring the WC testimony of Shelley and Lovelady.
Let's start with the fact that BOTH MEN testify that they didn't leave the steps for at least three minutes!!
How can they be on the extension seconds after the shooting??
I would really like to hear what Brian is going to make up off the top of his head to account for this.

BOTH MEN testify that, after three minutes, Gloria comes up to the steps, tells them about the shooting after which both of them make their way across the Elm Street extension to the "little, old island" (both men use exactly the same phrase to describe the concrete spur separating the Elm Streets), where they stopped "for a minute".

So, the image of the two men walking down the extension is taken 20 - 25 seconds after the shooting.
In this short span of time, according to Brian, Gloria has made her way back to the TSBD steps, told everyone about the shooting, both men have made their way across to the little old island, hung around there for a while, then made it half way down the extension before being caught on film.
Let's do him a favour and ignore the three minutes it takes Gloria to reach the steps and the time spent on the little, old island.
Even if we ignore all the testimony that Brian seems so willing to do, is it still physically possible for the two men to be so far down the extension, after the sequence of events described, in such a short span of time?
Let's be ultra kind to Brian and make it like some mad kind of tag race  being run at top speed:
1] Gloria sprints full tilt and makes it back to the steps within 15 seconds
2] She spits out a rapid-fire account of the shooting in 5 seconds
3] Shelley and Lovelady sprint across to the little old island - 3 seconds.
4] They stay there for 5 seconds
5] They then sprint to their positions on the Elm Street extension - another 3 seconds.

They still don't make it in time.
Even if we follow Brian's lead and ignore nearly every statement they made in their WC testimonies, Shelley and Lovelady still don't make it.

The reason for this is obvious - it's not Shelley and Lovelady on the Elm Street extension.
In reality, what happens is this
Shelley and Lovelady are on the steps at the time of the shooting.
Immediately after the shots Shelley runs out to the concrete spur where he encounters a distraught Gloria Calvery running the other way.
Both return to the front steps where Gloria tells everyone there about the shooting after which both Shelley and Lovelady make their way into the building through the front door.

Gloria reaches the steps in a matter seconds - not 3 minutes.
Both men do not then go across to the little, old island.
Both men do not wander along the extension.
Both men do not hang around the railroad yards.
Both men do not enter the building through the west door.
These are all lies told to hide their actual movements after the shooting.

Both men immediately enter the building and make their way towards the back of the first floor where they are seen by Vickie Adams about 60 seconds after the shooting.
Seconds later Baker and Truly arrive at the elevators where Baker notices two white men just hanging around. Clearly this is Shelley and Lovelady.



The image above shows the moment Gloria has reached the steps and is telling everyone about the shooting.
The man in front of her is Billy Lovelady.
Shelley, wearing his baggy black suit, is near the bottom of the steps after returning from the concrete spur.

    BUMP

While one is always entitled to engage in thought experiments, a thought experiment taking Vicki Adams' story at face value seems a stretch to me in light of the fact that Sandra Styles, her companion, always said she thought Vicki's time estimate was at least somewhat off and, more importantly, was adamant that Shelley and Lovelady were not there. Occam (or Ockham, if you prefer) tells me a more plausible thought experiment has Vicki conflating her and Styles' trip down the stairs with a slightly later encounter by her with Shelley and Lovelady when they reentered the TSBD. But, hey, that's just my and Occam's little thought experiment.

Bart Kamp summarizes what Styles repeatedly told Barry Ernest here: http://www.prayer-man.com/tsbd/sandra-styles/. Sean Murphy also followed up with her after Ernest's book came out. I also found a long discussion at Greg Parker's forum where the sentiment seemed to be that the "Shelley and Lovelady" question and answer had been fiendishly inserted into Vicki's actual WC testimony precisely to make it seem that she and Styles must have left the fourth floor window later than she thiought. Greg seemed to find this unlikely, and my thought experiment doesn't require any such shenanigans by the WC; in mine, the two cuties can have come down the stairs however quickly you like, with Vicki simply being a bit off as to when she saw Shelley and Lovelady.

(Lots of Sandra Styles' stuff for sale on eBay. Don't miss your chance: https://www.ebay.com/itm/175838680679. I may have got burnt on $1200 worth of Bogus Imposter Haygood autographs, but this Styles stuff is the real deal.)

   The "superior intellect" was duped into buying $1200 of "Bogus Imposter Haygood Autographs"?  WOWSER!

Note how Secret Service Agent George Hickey, having heard what he thought was a firecracker, leans far over and looks down at the pavement starting around Z-145, about one second after Oswald's first, missing-everything shot at hypothetical "Z-124," half-a-second before Zapruder resumed filming at Z-133.

Note how Secret Service Agent Jack Ready, on the passenger side running board, leans over to his right and turns his head around during the same time frame, and how Secret Service Agent Glen Bennett, below him, leans over far to his right, too. (He said he started looking at JFK after the firecracker-like sound and that he saw a bullet hit him in the back.)

JFK turns his head quickly to his left starting in Z-144 and then turns it back to his right and starts waving to Mary Woodward and her three journalism colleagues around Z-175.

Governor Connally, having heard the first shot and recognized it as such, first turns his head quickly to his left starting in Z-150, and then turns it far to his right, starting in Z-164, to catch a glimpse of JFK over his right shoulder. However, JBC can't "see" JFK in Z-180 (etc.) because he has turned his head far to his right, too, and has raised his arm to wave to Wooward and Co., thereby obscuring his face from JBC's view.

 We have to find a larger copy of the film to actually see what you're referring to.  I have analyzed this film sprocket area for years, since its release by MPI in 1998, and I can honestly say that at no time have I ever seen SS agent Ready "leans over to his right and turns his head around during the same time frame".  Ready's position, when he first appears in the film, shows him looking to his left, then his head turns and he faces forward, and before he disappears from the Z film, he looks as if he's looking in Zapruder's direction.
