There was no conspiracy in the shooting of JFK.
Just think. If Vice President Johnson, the Secret Service, Congress, the Supreme Court, the Army, the Mafia, the CIA, the right wing, Castro, and the Dallas police department had all plotted to murder Kennedy, they could have got some woman visitor to poison him any time. With Kennedy's long history of drug use, the cause of death would be easy to fake or conceal.
But arranging to shoot the president in public would take many reliable conspirators, lots of planning and rehearsals, flawless command and control, perfect secrecy forever. This couldn't work. Someone would let it slip or chicken out or spill the beans ahead of time. Or if the shooting did kill its target, someone would be caught and the matter pressed until the truth came out. No secret that big could be kept for long.
What if you dismiss all theories but the one about a second gunman? Then note the lack of evidence. No such person was ever caught or identified. Suppose he mingled into the confused and horrified crowd or casually strolled off the other way after ditching his murder rifle nearby. Yet no rifle turned up at the crime scene either. Without a shooter or weapon, what's left to believe about this?
