im going to suggest that BECAUSE prayerblob was NOT blackened out that Oswald therefore is not likely Prayerblob at ANY time in either Weigman or Couch/Darnell.
So if Alan Fords theory in this thread is that Oswald is out on the steps BETWEEN Billy Lovelady and Buell W. Frazier, the question is then: Would the conspirator film alteration experts fairly well blackened out Oswald, thus causing the vertical shadow, but forgot to blacken out the 2nd head?
