Your "singular" semantic argument gets 0 out of 10 from me.
Likewise your "Thornton" argument gets 0 out of 10.
I will give u a 10 out of 10 for the FBI report having the correct SE corner (it must have been me that was confused by Moore's word "cater").
I will give u 1 out of 10 for saying that Towner stopped filming before shot-1, if indeed she ever said that.
But i remember her saying that she couldnt recall whether it was just before or just after. And my film analysis says JFK was on Oswald's sight line to the signal arm at T137, slug arives at T138, sound arrives at T139, Towner finishes at T142 which is 3 frames after, but allowing 1 frame to reach Towner's brain, & allowing 1 frame for the ear part of the brain to tell the Towner part of the brain, then Towner "hears" shot-1 at T141, almost a draw.
I will give u 10 out of 10 for saying that Donahue drew Hickey high up to not only help his needed wound traject but also to get clearance over the windshield.
I have previously shown in my "was Hickey's AR15 in burst mode" thread that the AR15 needed to be more than 3" higher than the windshield (based on being on level ground), not Donahue's 18" (cant remember his exact number)(here i did not look into Donahue's wound trajectory).
The Bronson frame supposedly showing Hickey sitting at Z313 i have explained to be later than Z313. (I give u 1 out of 10 here).
And Hickey was half standing in that Bronson frame, Bennett was the one sitting low down.
I have explained all of that in my Bronson threads.
The superior 2019 Bronson frame (of that there inferior 2017 Bronson frame from Robin Unger's gallery) shows that the AR15 was rapidly swinging up at 45 deg. The frame that u tout that sinks the Hickey theory actually reinforces the Hickey theory.
I dont know why Zapruder & many others did not hear shot-1 being at Z113. (I give u 1 out of 10 here).
But many (including i think Zapruder) said that the first shot was at Z210 to Z230.
I think that this deafness might have been due to peer pressure & the passage of time.
And due to FBI etc pressure pushing questions & even answers the way they liked.
U will recall that the FBI could have questioned everyone near the signals etc but they questioned very few.
And these A-grade witnesses were asked questions such as "did u see anyone strange in the TSBD".
And "where were u standing".
And "how many shots did u hear".
Thank u mam, that will be all, oh, just one more thing, "what did u have for breakfast".
I forgive Donahue for his silly drawing. He is one of my heroes, having found that Hickey fired the headshot.
And Max Holland is a hero, for finding that shot-1 ricocheted off the signals (& i forgive Max for being a LNer).
And Colin McLaren is a hero (alltho i cant remember what his contribution was)(i think his only contribution was to draw attention to Donahue & Holland).
And i am a hero, for finding that Hickey fired a plurality of shots, alltho Floyd Boring was the one who first mentioned it many years ago, albeit to poo poo the possibility that Hickey fired, he said that if Hickey fired he almost certainly would have had the AR15 in AUTO, & that Hickey would have fired 2 or 3 shots not 1 shot. However i didnt know of Boring until this week. I figured it out myself. Anyhow that's my theory. It can be called mental ejaculation.
I bring certain skills. My background includes road design. Traffic accident analysis. Design of drain inlets & systems. Surveying. Design, drawing, drafting, CAD. Hence i find it easy to
look into much of this stuff.
Mostly i reckon that i can spot the difference tween truth & camel Helicopter

. Otherwise i would be a CTer or a LNer.
