Fake assassination. JFK killing video is fake. and if there were any witness on that day their voice won't be heard. well coordinated. Bush sr was there at the hospital making sure the plan works well. so much a stake.

there is some geo-politics in this drama. Big oil, saudi and Geek shipping (oil/gas) tycoon Aristotle onasis ambition to own the American oil instead of Gulf Aramco.
so it appears by staging this fake killing. Jackie was also datign aristotle the greek shipping tycoon and then married him after JFK death. she is actually a trojan horse of "CIA" . and soon later Aristotle's son and succesor is killed in a plane crash. his empire is doomed. and saudi arabia wins. Meanwhile (Mobster- today's obama/bush/clinton)
JFK has secretly escaped with marilyn monroe.
How do i know?
This is my conclusion based on all evidence on public domain, and after seeing the JKF movie by kevin costner. there is one scene where the secret service people are asked to go on leave. so a cover up.e.
