Part of the (presumed) complexity of the JFK case is the mountains of data generated over the years that some enthusiasts insist one masters before they entreat them: 'If you don't know sub-detail 'x' then you don't know anything'. Ironically, this measurement of minutiae over argument is the same one Lee used to declared victory over his ideological opponents, but this behavior is hardly confined to the JFK space.
Of course, this is false logic; Praexeology requires only the correct data analyzed correctly. The rest, as they say, is 'scenery for the public'.
