Oliver Stone did a follow up called JFK Revisited : Through The Lookin' Glass,
that was more of a documentary style, where they broke things down even further.
It's been awhile since I seen it, but one thing they proved, was there definitely was
a second shooter on the grassy knoll.
They even proved how when blood sprayed onto one of the policemen in the
motorcade, it came from the angle of bein' shot from the grassy knoll.
The US government is involved someway, 'cause they're the only ones with enough
power to cover so much stuff up.
It's a mystery wrapped in an enigma.
