The night before the Kennedy assassination, Lyndon Baines Johnson met with Dallas tycoons, FBI moguls and organized crime kingpins - emerging from the conference to tell his mistress Madeleine Duncan Brown that "those SOB's" would never embarrass him again. It's a jaw-dropping deposition and it's the biggest JFK smoking gun there is - despite the fact that it has received little media attention.

Before her death on June 22 2002, prolific author and lecturer Robert Gaylon Ross had the opportunity to conduct an 80 minute sit-down interview with Madeleine Duncan Brown and from that lengthy discussion the truth about exactly who was behind the assassination of JFK was exposed.

Though Brown first went public on her 21-year relationship with Johnson in the early 80's, to this day her shocking revelations about how he had told her the Kennedy's "would never embarrass me again" the night before the assassination are often ignored by the media who prefer to keep the debate focused on issues which can't definitively be proven either way (or at least can be spinned and whitewashed).

It is important to note that before her death Brown carried no hostility towards Lyndon Johnson and in fact was just as smitten with him as on the first day they met.

Brown said that the plan to kill JFK had its origins in the 1960 Democratic Convention, at which John F. Kennedy was elected as presidential candidate with Johnson as his running mate, where H.L. Hunt, an American oil tycoon, and Lyndon Johnson hatched the assassination plot.

"When they met in California Joe Kennedy, John Kennedy's father, and H.L. Hunt met met three days prior to the election - they finally cut a deal according to John Currington (an aide to H.L. Hunt) and H.L. finally agreed that Lyndon would go as the vice president....this came from the horse's mouth way back in 1960 - when H.L. came back to Dallas I was walking....with him....and he made the remark, 'we may have lost a battle but we're going to win a war,' and then the day of the assassination he said 'well, we won the war'," said Brown.

Brown said that in the immediate aftermath of the convention Hunt and Johnson mapped out a strategy to kill Kennedy.

"It was a total political crime and H.L. Hunt really controlled what actually happened to John Kennedy - he and Lyndon Johnson," said Brown.

"They had this lodge....outside of Dallas and they would meet there....he chose different people to do certain things for him and I'm sure it went on about two years prior to the assassination of John Kennedy."

In the video Brown describes the make-up and activities of the "8F group" which revolved socially and politically around Johnson and Hunt and included high rolling oil tycoons, judges and then FBI director J. Edgar Hoover.

The group included Jack Ruby, the Dallas nightclub owner who would later shoot the patsy Lee Harvey Oswald dead on November 24.

"We were playing poker at the Carousel Club and Jack Ruby came over and he said 'you know what this is?' and I looked up....he had this motorcade route....it stung me that he would be this involved in knowing where the President of the United States was....at that time in my life I thought they were untouchable," said Brown.

Brown described Ruby as the "in man" in Texas who could be trusted to arrange call girls, drugs, gambling fixes and even contract killings.

The group met for a party in Dallas hosted by Clint Murchison, another business tycoon with close links to the Genovese mafia, on November 21st 1963, the night before the assassination. Those present at the event included J. Edgar Hoover, Clyde Tolson, John J. McCloy, Jack Ruby, George Brown (of Brown and Root), numerous mafia kingpins, several newspaper and TV reporters, and Richard Nixon.

The party began to wind down at around 11 o' clock when the attendees were shocked to witness the arrival of Lyndon Johnson who had traveled from Houston. Clint Murchison immediately called a meeting.

"They all went in to this conference room.....Lyndon didn't stay that much in the meeting and when he came out....he grabbed me by the arm and he had this deep voice and he said, 'after tomorrow those S.O.B.'s will never embarrass me again - that's no threat - that's a promise.'"

Johnson was still irate when he called Madeleine Brown the morning of the assassination, telling her the Irish mafia (meaning the Kennedy family) would never embarrass him again.

Brown was in Dallas in the day of the assassination but just as the parade for Kennedy was beginning she left and began driving towards Austin, first stopping off to have a haircut. Upon entering a hair salon she saw the news that Kennedy had been shot and immediately thought to call Lou Sterrett , who was an Austin media mogul.

"I said my God what has happened Lou?"

"And he said 'well they just shot that S.O.B'"

"It was a political crime for political power," said Brown as she highlighted how people who were set to testify against Johnson for indictment proceedings, related to illegal kickbacks Johnson was receiving from agriculture programs before the assassination, were mysteriously set-up in homosexual scandals or found dead having allegedly shot themselves five times in the head.

"Had the assassination not happened the day that it did, Lyndon Johnson would have probably gone to prison - they would have gotten rid of him - he was so involved with some of this," said Brown.

Having had her own (and LBJ's illegitimate) son and nanny disappeared by Johnson's hitmen after the assassination, and upon hearing of the strange deaths of many other people connected to the events in Dealy Plaza, Brown felt that she was safer out in the light and decided to let the world hear her story.

It's a story that simply hasn't got enough attention, besides a 2003 book written by Barr McClellan, father of White House press secretary Scott McClellan. Hopefully this article and the video clip contained therein will help to bring more attention to perhaps the biggest smoking gun proving that the assassination of JFK was an inside job planned from the very top years in advance.

If they had the gall to blow the President's head off in broad daylight with the world's media watching over 40 years ago - what would stop the same lineage of criminals from carrying out 9/11?
