The corset did not kill Kennedy and neither did Oswald. I am conviced he was set up as a patsy and although in the Texas Book Depository that day, he was not on the sixth floor.
I still believe the fatal headshot came from the front not the rear. I am not so sure the first shot that penetrated his throat back to front would also not have been fatal. It pierced his trachea and larynx and it is possible he could have drown in his own blood before he got to Parkland.
Again, all this is still conjecture on my part, no one will ever really know for sure. It happened 41 years ago, all the players are either very old or dead and a lot of vital evidence was either lost or buried by the conspirators.
He thought the whole thing up on a moment's notice, and did it all by himself with no outside help whatsoever.
It was also not Oswald's first assassination attempt on a notable public figure.
I still believe that too.
