Secret Service left the motorcade before the assassination happened.
No doubt that LBJ was behind such a cover-up and a crime which needed the cooperation of the secret service, the FBI and most of the agencies. I am very pro-US but in that case, it was without any doubt an inside job. No foreign government or organization could control the inquiry and Kennedy’s bodyguards as it happened.
