I caught a bit of this last night, I forget which channel.
I hadn't seen it in years and didn't pay too much heed to it when I did.
But watching the court scene again where Costner's charachter sums up the evidence, it makes a powerful case for a conspiracy behind Kennedy's death.
Probably the most crucial evidence is the president's head going 'back and to the left' with the fatal rifle shot, clearly from the impact and force of a bullet coming from on front and to the right of the presidential limo.
There is also no way Oswald could have been in the 6th floor of the book depository.
The guy was clearly framed for the assasination.
I'm not sure what forum this belongs, so mods move if you feel the need.
Probably the greatest conspiracy of the 20th century and no-one ever brought to justice.
Watch the film the next time it's on TV, well worth it.
