If they were REALLY on top of this they would know that back in the late 1960's ENQUIRER magazine "proved" that Kennedy was not really killed but only wounded so bad he was mentally unfit to serve out his term.
Long distance photos showed a man looking like JFK in a wheelchair and his head bandaged on the Onassis Islands.
But then there are those peskey morgue photos...
Kennedy is deader than a doornail. Morgue photo's don't lie. There was no such thing as Photoshop in '63.
