Oswald was a CIA operative. He knew about the plans to kill JFK. Oswald sent a memo to every FBI office alerting them to an impending assassination attempt on JFK, I believe one week before the shooting.
Oswald did not shoot JFK, but I suspect he knew who might be involved. He was as he indicated, a patsy. And he was killed for multiple reasons, but largely, to shut him up. He knew too much.
Anyone that renounces their citizenship and goes to the country of Russia was considered a traitor back in the day. A few years later, he returns from Russia with a wife and child. Our embassy paid to fly him and his family to the states.
Where did this so called traitor work when he got back? At a place that was tied to the military requiring top secret clearance. Does a traitor get top secret clearance in the USA?
There are so many lies in regard to Oswald through the years. Oswald did not kill anyone that day. He was set up.
And I would not be surprised if George H. W. Bush was directly involved with JFK's assassination. Not in the least.
And I believe it is time to end the CIA. Fire every person there except those in the field. God knows what they are doing, they answer to no one!
