You might like this to be done with, but Thompson differs with you. My siren solution would put it to bed one way or the other. This is EXACTLY why these unresolved issues continue to dog this case. People with skin in the game actually want it to drag on. You're Welcome!
No, I know it is over with. I know Thompson differs with me, and I know why/how. He's a believer in the BS that Don Thomas has in his book, and this is the only reason Thompson differs with me. The fact that Thomas is full of crap with his "crosstalk" (that doesn't exist) which he claims proves there are still gunshots on the Dictabelt, is ludicous on its face. And Thomas knows it! I put it to bed in my piece which not only Bugliosi published in his book, but Dale Myers published on his Secrets Of A Homicide Website when I explained what Thomas has done with a channel 2 transmission which says is picked up by the open microphone, and so it also appears during the open mic sequence, therefore was recorded onto the Dictabelt.
I'm not going to go into all of it, I'm going to provide the link to my piece on Dale Myers' Website. It's irrefutable proof that what Thomas says is a transmission from channel 2 being picked up by the open mic is NOT-NOT "crosstalk". Period.
https://jfkfiles.blogspot.com/2007/07/of-crosstalk-and-bells-rebuttal-to-don.html Thompson agrees with Thomas, and had I known this when Thompson was interviewing me in 2014 for his book "Last Second In Dallas", I would have saved him a ton of trouble.
You have nothing to offer regarding the acoustics.
