However, the Warren Commission, established by President Lyndon B. Johnson to investigate the assassination, concluded that Lee Harvey Oswald acted alone in shooting Kennedy. This conclusion has been supported by the majority of experts and the majority of the American public.
"They want a force of American troops. The troops will march in... and in four days everyone will have forgotten. Then we will be told we have to send in more troops. It's like taking a drink. The effect wears off and you have to take another."
