The reason. I believe I know who did arrange for JFK to be killed, and I know the motive, and what else was arranged at that time.
Power, lust, and money. These are always at the base of evil acts.
WHO WANTED JFK killed? Well, think of what happened previous to his death.
Who is a member of Organized Crime, and one of the most powerful people in California and New YorK?, the most powerful in the entertainment industry? Who supports Democratic Presidents (and puts them in office)? Think, think, think.
What about Gen. Walker? The issue at this point is the attempted assassination of General Walker, not JFK.
From The Walker Assassination Attempt:
Marina Oswald has remained utterly consistent as regards the main points of her testimony. She repeated them to the House Select Committee in the late 70s, to author Gerald Posner, and even the NBC TV account of her experiences broadcast in November 1993 (which had a strong conspiratorialist bias) repeated her account of Lee coming home late at night and telling Marina he had shot a Walker.
The question remains: If Oswald did not try to kill Gen. Walker, is Marina Oswald in on the conspiracy? Why does she insist, to this day, that Lee Harvey Oswald tried to kill him?
