Oswald's murder, you mean?
Well, there was this feller nicknamed 'Sparky' for his quick temper, he wasn't all there to begin with according to everyone who knew him, who owned a risque night club and was buddy with the cops.
He also liked Kennedy. A lot. The day of the assassination he told one of the girls who worked for him that if he had his gun with him he'd shoot Oswald if given the chance.
So he took his gun and was in the back of the room where Oswald gave his press conference.
On Sunday morning he went to the police station, where everyone knew him and thought nothing of letting him walk in freely, and shot the b*stard who, as he put it "killed my president."
The first thing this fellow said to the first Secret Service agent to question him was "I wanted to show the world that a Jew had guts!"
As my ex-father in law used to chuckle and say when the subject of Oswald's murder by Jack Ruby came up, "there were probably 10,000,000 other guys who'd have done the same thing that morning if they'd had a chance."
Oswald died because the Dallas police was negligent in carrying out their duties, not because there was a conspiracy to kill him.
One nutty lone gunman was killed by another.
Case closed.
