More Dr. Thomas fanboy babble, and your assumptions are entirely wrong.
You claim the Decker cross talk is "out-of-place".
Now you need to explain exactly what you mean by "out-of-place" and how it ended up there, Mr. Science.
Ok, only for the sake of others, I'm going to answer this, again. I say "again" because I have already addressed, several times, the issue of how Decker's "hold everything" crosstalk ended up on Channel 1 at a point just after the final gunshot on the dictabelt. This issue has been covered, like, a zillion times in the research. There are several ways that crosstalk can occur on dictabelt recordings, not just the DPD dictabelt: recorder stoppage, stylus displacement, over-recording during copying, and speed warps.
Do you really need me to explain what "out of place" means? Seriously? Well, ok. The "hold everything" crosstalk is out of place on Channel 1 because it occurs at a different time than it does on Channel 2; its broadcast time on Channel 2 is 60 seconds after Curry's "to the hospital" transmission, but its broadcast time on Channel 1 is over 60 seconds earlier.
The gunshots occur on Channel 1. They occur right around 140 seconds after the 12:28 time notation on Channel 1, which means they occur at 12:30, just as they should.
As I've discussed several times, we can check this timing via the simultaneous Fisher crosstalk, Curry's "triple underpass" transmission, Curry's "to the hospital" transmission, and the 12:30 time notation on Channel 2. The first gunshot pattern occurs just after the Fisher crosstalk and Curry's "triple underpass" transmission, and both of those transmissions occur *before* the 12:30 time notation on Channel 2.
The fact that Fisher's crosstalk is simultaneous is important because it gives us a two-channel time correlation, and it comes just before the 12:30 time notation on Channel 2 and about 138 seconds after the 12:28 time notation on Channel 1. Furthermore, the dictabelt gunfire ends just before Curry's "to the hospital" transmission, which comes about 12 seconds after the 12:30 time notation on Channel 2. A perfect, powerful fit that shows clearly that the dictabelt gunfire was recorded during the assassination.
So if you are going to continue to insist on using Decker's "hold everything" crosstalk as your time indicator, you need to explain how you can do so in the face of the clear evidence that his crosstalk is totally unreliable as a time anchor, and in the face of the powerful synchronization between the gunfire, the Fisher crosstalk, the time notation on Channel 1, the time notation on Channel 2, and Curry's two transmissions.
The BBN scientists knew better than to use unreliable crosstalk events as time indicators. Instead, logically enough, they used the time notations on Channel 1 and Channel 2. The NRC panel members, not being acoustical experts, apparently did not realize they were committing an egregious error by using the most anomalous crosstalk event as their time indicator. (Or, perhaps they knew this was a bogus approach, but it was the only one that enabled them to claim that the gunfire impulses on the dictabelt were recorded after the assassination and thus "had to be" something other than gunfire.)
I have not even mentioned the Bellah crosstalk yet, which is another indicator that the dispatcher time notations are accurate and that the gunshots were recorded during the assassination.
Now, I ask you, yet again: Why should we pick Decker's "hold everything" crosstalk as the time indicator instead of (1) the Channel 2 dispatcher's 12:30 time notation, (2) Fisher's "I'll check" simultaneous crosstalk on Channel 1, which we know comes just *before* the 12:30 time notation on Channel 2, (3) Curry's "triple underpass" transmission on Channel 2, which we know also comes before the 12:30 time notation on Channel 2, and (4) Curry's "to the hospital" crosstalk on Channel 1, which we know comes 18 seconds after his "triple underpass" transmission on Channel 2?
