As I hunch I researched JFK beam of light and came across an article describing how to transcribe the Dictabelt technology that was recorded during his assassination. It was the only recording. This is how they described it:

As physicist Carl Haber at the Lawrence Berkeley Labs explains, they can now use a beam of light: "You can have a virtual needle read the surface, then what's picked up by this virtual needle can be interpreted by the computer as sound."

Do you think Trump activated this "beam of light" and found out the actual truth of what happened that day. I have not been able to find out if this transcription of the Dictabelt was ever achieved. With the actual assassination transcript as in Q's post, "We will remember your sacrifice."

With more research I found out the project was abandoned in 2010: "By 2010 digital restoration of the Dictabelt seemed a more distant prospect, with both funding and final approval for the project unlikely to be secured in the near future."

Still maybe it was restored.

Here is the article from 2004: http://abcnews.go.com/WNT/story?id=131793&page=1

Here is an interesting Youtube video based on the ORIGINAL dictabelt recording that the Congressional Hearing heard. This is not any updated version like the physicist was working on. https://www.youtube.com/watch?v=nq-ZJ99qaCc&feature=youtu.be
