Personally I think that the forensics speak for itself and the bullet in the back of John f Kennedy kind of proves the entire situation with a 6 mm hole.
For those of you that don't know simple physics a 6.5 mm manlicher carcano will not pass through the hole in John f Kennedy's skull.
However the secret service follow up car had an AR-15 in 5.56 mm for the bullet diameter. Which is another reason why the secret service really frowns upon the AR-15 over a simple mistake and negligent discharge that ended up killing the person that they were supposed to protect.
Yeah a while back there was a forensic technician that decided to look into this and with his background in ballistics came up with some really interesting findings. Mainly that yes Lee Harvey Oswald did shoot the president with one round that entered the back shattering the spine and exiting the throat.
The seating positioning in the vehicle really adjusts the missing bullet or magic bullet theory.
Let's say for brevity is sake that this author has really been pushed under the bus as well as had quite a bit of career issues resulting from publication of his book.
However now we have a little bit of an intelligence tease by the current administration in releasing 1500 pages of what I'm going to guess is absolutely nothing and has absolutely no real intelligence value even though this has happened so far in the past that most of anyone who involved has passed away.
Well the conspiracy theory is still alive and well that there was a major situation involving the world intelligence services.
However once again truth is being covered up.
