I know a guy out here who has a book that says JFK was shot by accident by the Secret Service.
He told me that the Secret Service had a full auto M-16 with the safety off in the follow car. When Oswald started shooting, the agent picked up the rifle and started to look for where the shots came from. The car lurched and the agent's finger pulled the trigger, shooting Kennedy in the back of the head.
When they called Bobby, they said, "Bobby, there's been a terrible accident."
Don't expect the family to ever admit to this, since they want JFK to be a martyr.
I heard that Israeli intelligence started the rumor that JFK was killed by accident. Oswald did not shoot anything that day. His position from the depository made it impossible to kill Kennedy. That is according to America's best sniper in the Vietnam war Carlos Hathcock. JFK was shot from the front according to the Zapruder film.
Go to YouTube and type in JFK Secret Service. Does this look like a plan or an accident?
JFK was killed for a reason. Some say it is because he signed an Executive Order that created United States Notes, a direct threat to the Federal Reserve. ;)
