The base of the Criminal Courts building appears to be at elevation 430ft. The limo elevation at z273 = 430 - 12.97ft (that's using z313 @ elevation 418.48 per CE884).

The "base" distance from z273 to the Criminal Courts building is 242.8ft. https://drive.google.com/file/d/0BwrExtVD005OYnpBdm9JenNKeWc/view?usp=sharing

David, You're looking at what's going to give you a 25 degree angle from the Dallas County Criminal Courts.

The rooftop of the Dallas County Criminal Courts building is listed as 120ft high. https://drive.google.com/file/d/0BwrExtVD005ORkNleXdnNVQ4S1E/view?usp=sharing

Here's what it looks like plotted: https://drive.google.com/file/d/0BwrExtVD005OcXdZeGRwTFhXd1k/view?usp=sharing

The red line provides a LOS traversing the light post and the Z pedestal. In other words, if you are Zapruder at approx z273 and you tilt the camera upward, guess who/where you would see on the other end? https://drive.google.com/file/d/0BwrExtVD005OZXFrWko4VVlpd28/view?usp=sharing

If Dr.Shaw had listened to Dan Rather's description of Connally's actions/position, knowing that Rather was trying to connect it back to the TSBD, he would have realized or did realize where that shot actually came from. https://drive.google.com/file/d/0BwrExtVD005OQ2Fpd2pJN2prd2c/view?usp=sharing

In case others had forgotten: 11.2mph = 7.475 + 3.735 https://drive.google.com/file/d/0BwrExtVD005OWHdpUkZUX29MaHM/view?usp=sharing 3.735 = 1/2 of 7.47 3.735 = 1/3 of 11.2 7.47 = 2/3 of 11.2

Q1. The Itek study is four frames per entry: A2-A6 = z285-z289 A6-B = z289-z293 which is where the aberration in limo speed occurs. Q2. z289 + (48 frames /2) = 24 = z313 I'm not describing four frames within z301-z313.

This is how I would distinguish the difference between the 7.33ft/7.205ft which equates to 7.6mph/7.474...mph using what I have already supplied: 1.5mph x 1.47ft per sec = 2.205ft 4frames/18.3 = .2185…sec .2185sec… x 2.205ft = .4819ft… .4819ft… / 4frames = .1204ft per frame 7.205ft + .1204ft = 7.325ft…

David, What happens to the limo speed on film when it's moving at 3.74mph 3.737… mph and half the frames are removed?

7.205ft x (18.3/12)1.525 = 10.987625ft per sec / 1.47 =7.4745… / 2 = 3.737… mph Refer back to these: https://drive.google.com/file/d/0BwrExtVD005OS0RxREpjXzRCSmc/view?usp=sharing https://drive.google.com/file/d/0BwrExtVD005ONHcwYnZEeDRPRkU/view?usp=sharing

I believe the distance traveled from Z301-z313 = 7.205ft, which is slightly less than the Itek study. (See previous link) 7.205ft x (18.3/12)1.525 = 10.987625ft per sec / 1.47 =7.4745… / 2 = 3.737… mph Why!!!

The last 12 frames of the Itek study: The average of 7.6mph for this span = 7.33ft(z301-z313) traveled. 7.33ft x (18.3/12)1.525 = 11.178...ft per sec / 1.47 = 7.60… mph https://drive.google.com/file/d/0BwrExtVD005OekFNcjdFUlVqS1E/view?usp=sharing

Itek data results connected to CE884's: https://drive.google.com/file/d/0BwrExtVD005ONHcwYnZEeDRPRkU/view?usp=sharing

Excerpt: "BREHM expressed his opinion that between the first and third shots, the President's car only seemed to move 10 or 12 feet. It seemed to him that the automobile almost came to a halt after the first shot, but of this he is not certain. After the third shot, the car in which the President was riding increased its speed and went under the freeway overpass and out of his sight. " Even with the 10.7mph aberration, the distance traveled is 12.3ft. At a constant 9.2mph the distance = 11.8ft Translated: After Connally took shot 1, the limo traveled approx 10-12ft until z301, where it almost stopped and kept that speed until shot 2 at extant z313, after the third shot which blew JFK's head off (Altgens), the limo accelerated. I refer to three shots as only occurring after extant z280, there were more shots previous to this point. https://drive.google.com/file/d/0BwrExtVD005ObnZ1TkNlUEFHYTg/view?usp=sharing

https://drive.google.com/file/d/0BwrExtVD005OREFwQTR2ZTJEYUk/view?usp=sharing Itek's study of limo during its last 28 frames of travel ending at extant z313. btw, 313-28 = frame 285 https://drive.google.com/file/d/0BwrExtVD005Oc19wcXJBUTBHRVU/view?usp=sharing

Frame Removal: The limo (according to Sam Kinney-driver of the follow-up car) slowed down from between 3 to 5mph. In this case, frames within a given time period (circa extant z280-z347) existed and we were led to believe this represented the true count. Yet, at least half of these frames were excised. Lets explore this:

The TSBD is 100ft long. If I move a shooter from the east end to the west end that's approx a 100ft move. The difference between 240ft and 143ft = 97ft. That would seem fairly close to 100ft. https://drive.google.com/file/d/0BwrExtVD005OZDQyTG9XeTZGQ1E/view?usp=sharing

265ft -240ft = 25ft https://drive.google.com/file/d/0BwrExtVD005OaGNId0g3UWRsakk/view?usp=sharing

https://drive.google.com/file/d/0BwrExtVD005OS0RxREpjXzRCSmc/view?usp=sharing Why did Greer take his foot off the accelerator and look back? He was reacting to Connally being shot circa 24.6ft (Station# 4+40.7) previous to the extant 313 shot. Very close to where Cutler labels "JFK within the limo" at extant z285. https://drive.google.com/file/d/0BwrExtVD005Oc19wcXJBUTBHRVU/view?usp=sharing
