You want some fries with that nothing-burger?
And does your 'counter-narrative' include the comment about Earlene having only a couple of seconds to see if Oswald was wearing a jacket or not? It must be, since I've schooled you on this very point before, using a similar blurred, mocking image... and yet here you are repeating yourself.
And did you finally work out if the figure in my mocking-mockup (so-to-speak) is wearing a jacket or not?
Pathetic.
As you haven't got a clue on how blurred Roberts' vision really was, your blurred picture is meaningless.
There is a major difference between briefly seeing somebody walking behind you, needing only seconds to get from his room to the front door, while you try to get the television to work and a picture frame from a Gary Mack video which you can watch as long as you like.
But I'll play, just for fun. The video shows the man wearing a jacket, so there is no mystery there, but if this guy would walk passed you in a matter of two or three seconds, under the same circumstances as Roberts saw him, you could easily confuse the jacket for a vest, cardigan or sweater.
