A DALLAS WOMAN MAY BE ABLE TO OFFER A NEW ANGLE ON THE KENNEDY ASSASSINATION. SHE'S KEPT IT QUIET FOR 32 YEARS-- BUT NOW PATSY PASCHALL SAYS SHE'S READY TO PART WITH FILM SHE TOOK THE DAY OF THE MURDER. PASCHALL'S FOUR MINUTE FILM WAS SHOT FROM A WINDOW OF THE OLD DALLAS COUNTY COURTHOUSE. UNLIKE THE FAMOUS ZAPRUDER FILM, PASCHALL'S DOES NOT CAPTURE THE ACTUAL KILLING. BUT IT SHOWS THE CHAOTIC SCENE IN THE MOMENTS AFTER THE ASSASSINATION-- IT EVEN SHOWS ZAPRUDER DOING HIS FILMING. THE F-B-I HAS SEEN THE FILM, BUT IT'S NEVER BEEN VIEWED BY THE PUBLIC.
