What factor is the culprit behind JFK ination and why?

ET...why? undesireable civilian response to disclosure in test groups [religous implications]...if you don't beleive the truth is out there, atleast question the forensics: his body was lost then recovered within 4 hours, bullet randomly appeard on the wrong strecher: no blood, no impact dammage or scratch...questionable 1 bullet trajectory, bullet hole in windshield, driver slows down-looks at JFK-then speeds up right when he's shot, disregard for open windows, JFK's bodyguards ordered to fall back (the guy who climbs on the car is his wife's SS) and how about the fact that if you hang around the plaza too long, armed security guards will ask you to leave to this day.
