The movie JFK made a big deal of this exchange between Earl Warren and Jack Ruby..showing it as proof of this massive interluken conspiracy.

But after reading the transcript I've come to the conclusion that Jack Ruby was mentally retarded or just a bold faced lying bastard.

Conspiracy? Nope. He believed there was one but he certainly had no personal idea or knowledge of who it was.
