Can't be an Oswald look-alike because Harvey went out the Loading Dock and down Houston...
The only Oswald that could be is Lee and 1) It obviously isn't him... 2) Lee was seen by Helen Forrest coming out from behind the west rear of the Depository and going right to the Station Wagon that was seen by Robinson and Craig...
dang, that’s exactly what I was about to say, Albert. a great brain cell thinks alike, oui?
