The Kennedy assassination has also spawned dozens of books and numerous newspaper and magazine articles claiming to have 'exposed' a plot to kill John F. Kennedy in Dallas, Texas on November 22, 1963. None of it is ever validated and now, a half-century past the assassination, the number of people who care are rapidly dwindling. Most Americans either believe Kennedy was killed by Lee Harvey Oswald with his mail order rifle or by a sinister plot engineered by anyone from LBJ to Fidel Castro to the Italian Mafia or the KGB, ad infinitum.
In both cases (Diana and JFK) they are long gone and it's extremely doubtful that any 'plots' to kill them will ever be substantiated. Sometimes, things really are as they seem. That doesn't excite anyone so it is often dismissed. Still, the seemingly endless 'questions' into the death of Princess Diana are getting rather repetitive and boring. Shes gone. She died in a horrific car crash. End of story. Now, let it go.
I agree with you mostly. Yes, Lee Harvey Oswald shot Kennedy but there sure were a lot of odd things happen.
My guess is just what you said but Oswald sure did have a lot of Communist connections.
