Sorry, Bill, you're wrong. Everything is just too pat, too perfect for all of this to happen like the WC tries to convey it to be. You can't have it both ways - we can't have Oswald like a "Tim McVeigh" - a loose cannon nobody who just decides to take a shot at Walker and then kill Kennedy - and then have all of these people in his life (Paine, George, Hosty, the folks down in NO) guiding him and Marina along, finding jobs for him, discovering evidence after the fact, saying they didn't like him but doing things for him.
Life doesn't work that way. I often imagine my own life (and you should too) - Oswald had to have been the luckiest person on Earth for all of things to have happened to him, by total strangers no less. But it wasn't luck - it all happened to lead up to 11/22.
If you can't get your head around it, then that's on you.
