Some JFKA researchers and students believe Lovelady and Shelley are the two men who can be seen walking/running down Elm Street Extension towards the railway yard / parking lot some 20 seconds after the final shot in Couch/Darnell.
It's physically impossible for those two guys to be Lovelady and Shelley, because 20 seconds wasn't enough time for them to have gotten as far down Elm Street Extension as we see them in Couch/Darnell after being told, near the "island" or at the steps, by Gloria Calvery -- who had to run a long way to get to the "island" -- or even worse, the steps -- that JFK had been shot.
Shelley and Lovelady said after the final shot, they raced from the steps across to the "little old island" where they stayed for a "minute or two" until Calvery reached them and gave them the bad news.
Is this physically possible in the given timeframe?

Dear danny BOY o'meara,
Mark Tyler has Gloria Calvery running up Elm Street towards the TSBD, conferring for about ten seconds with a couple of people in the intersection of Elm and Elm Street Extension, and finally arriving at the steps about 25 seconds after the final shot.
He has Marrion Baker arriving at the steps 30 seconds after the final shot.
Just looking at the Darnell clip, we can see Calvery as she's standing on a lower step with her back to the camera, apparently talking with the man in front of her, but we don't know how long she's been there.
We can, however, see Officer Baker as he's running towards the steps and he's almost there.
Calvery and her three South West Publishing Company colleagues (one of whom can be seen running past Lovelady and Shelley / "Lovelady and Shelley" towards the TSBD entrance) weren't very far down Elm Street from the "island" or the steps while they were watching the motorcade.
I suspect that Calvery and her dressed-in-white colleague next to her on the steps could have gotten to the front steps in about 15 seconds if they had run non-stop, giving Calvery plenty of time to relay the bad news to Lovelady and Shelley, and for Lovelady and Shelley, in turn, to get as far down Elm Street Extension as we see them in Couch/Darnell.
Regarding Lovelady's and Shelley's allegedly waiting "a minute or two (or was it three?) for Calvery to get to them, do you really think that's realistic?
