See the movie "JFK II" at PrisonPlanet.tv. 
(I found a copy that someone had posted Nov. 8, on usenet: alt.binaries.goat).
It seems to say (among other things) that: George H. W. Bush was (on Nov. 22, 1963) directly involved in the "doctoring" of the forensic evidence, which would have conclusively proven: from what direction the bullets, that hit JFK, came from.
That Lee Harvey Oswald was, at the time of the assassination, a paid FBI informant (concerning Cuban exile training camps in Louisiana). 
And, that George H. W. Bush brought along with him CIA man/Watergate burglar E. Howard Hunt, when they both became part of the Nixon Admimistration. 
Towards the end, the movie also questions the whereabouts of our current President George W. Bush, on the day that John Kennedy Jr. died in a plane crash.
Makes you think...
