Everything about the JFK assassination points to Lyndon Johnson. He had the most to gain, he had the ways and means to accomplish it, and he was in a position to cover it up afterwards. He also had the psychological make-up to commit such an act. Those who knew Johnson say that he would stop at nothing to achieve his ultimate goal of becoming president of the United States. Johnson has been described as power-hungry, ruthless, and manipulative. Those traits alone don't prove that he killed John Kennedy, but when looked at in the context of Johnson's life and political career, there is no reason to doubt that Johnson was at the center of the plot.
