One more post to add to the list of those which do not logically explain why Oswald was seen on Jefferson with no jacket even though he left the rooming house on Beckley zipping one up as he went out the door of the rooming house.
If I were among the pathetic Oswald defenders, I too would take the lame position that "it is highly doubtful" that Oswald left the rooming house with a jacket. It's all you have in order to not have to explain why he no longer had the jacket on Jefferson.
All you have to claim that Oswald left the rooming house with a jacket is a comment by Roberts about a zipper.
What you can't explain is which grey jacket Frazier saw Oswald wear to Irving the previous day, if it wasn't the only grey jacket he owned.
There is enough reasonable doubt about Oswald leaving the rooming house with a jacket to make your question superfluous.
