Jack Ruby, the man who shot and killed Lee Harvey Oswald within 48 hours of JFK's death stated the following:

Jack Ruby: Everything pertaining to what's happening has never come to the surface. The world will never know the true facts, of what occurred, my motives.

The people had, that had so much to gain and had such an ulterior motive for putting me in the position I'm in, will never let the true facts come above board to the world.

Reporter: Are these people in very high positions Jack?

Ruby: Yes.
