JFK's assassination was a vast conspiracy, likely connecting both the CIA/FBI and the Mafia who both had good reasons for JFK to be gone.
Kennedy was going to cut the CIA's budget and was considering closing the agency down. They blamed him for the failure to take out Castro.
The Mafia hated the Kennedys. JFK and brother RFK, the attorney general were campaigning hard on taking them on and causing trouble for them.
Oswald was the perfect patsy. The CIA and many others felt JFK was too soft on communism. What better assassin than a communist, military reject.
The 1979 Select House Committee found that Kennedy was likely killed as part of a conspiracy and that Oswald did not act alone.
The magic bullet theory is bullshit. Not only are we supposed to believe that the bullet that killed Kennedy magically also went through a seat, and into and out of the governor, but was also found in the hospital still in emaculate shape. Pleeeease!
The Zapruder film clearly shows Kennedy was shot from the front, likely from the grassy knoll, where several witnesses heard shots from and saw smoke.
Oswald claimed himself, he was a patsy. The Mafia sent Jack Ruby (Who's club Oswald frequented) who was probably let in, to shoot Oswald, not because he felt bad for Jackie, but to silence Oswald from revealing the existence of a conspiracy.
LBJ was also likely involved. He ducked just before the shots rang out in his own limo behind the President's and shared a wink and a smile after being sworn in. (I have also heard when he turned to the man he winked at, he said, we did it, but I can't confirm that)
LBJ had a good reason to be involved. JFK was considering dumping him as his VP for the coming election. LBJ a far more conservative man than Kennedy, felt he was weak. LBJ was someone who did what he had to, to get elected (see his Texas election scandal).
