According to Gary Mack, curator of the Sixth Floor Museum at Dealey Plaza, changes in Hill's story over time led some researchers of the Kennedy assassination to consider Hill a "controversial witness". Others argue that her testimony was both reliable and that "the strong patriotic convictions that bound Jean Hill to defy the official report of the Warren Commission", and the fact that "she received no compensation, and a lifetime of woe" add significant credibility to her testimony and also at the same time call into deeper question the conduct of some officials on the day of the assassination and in the investigation that followed. The controversy over Hill's testimony continues as a part of the larger debate and ongoing research into the Kennedy assassination.
