The disbanding of the CIA was something I had read a couple of times and heard a couple of times so I by no means have evidence of that either.

As far as Oswald goes everything I've ever heard about him indicates that he was not exactly a stable personality. And this was the president of the US who usualy has an extreme amount of security. I've just always thought it was a pretty expertly executed assasination for Oswald to have doen it himself.
