It has long been assumed by researchers on both sides of the debate that the Hughes film shows Mr. Billy Lovelady shielding his eyes from the sun at near-bottom left (=west) of the doorway, just above Mr. Carl Edward Jones---------------

I'm not so sure about that........
On 19 March 1964 Mr. Lovelady tells FBI this---------------------

The day before, Mr. Shelley tells FBI this--------------------

Standing vs. Sitting = Contradiction? Not necessarily!
Each man's statement comes not just with a clear
location marker
---------"on the top step to the far right against the wall" vs. "just in front of me"
but with a clear
time marker too
---------"At the time the Presidential motorcade passed the Depository building" vs. "At the time... was shot"----------,
such that the following is suggested:
Mr. Lovelady is
standing (back in the shadows) in order to catch a glimpse of Pres. Kennedy as the limo passes; Mr. Lovelady
sits (back) down after this, and is seated when the first shot rings out; Mr. Lovelady immediately
returns to his feet and tries to see what's going on down the street (he is captured in this posture in Altgens)
Neither Mr. Lovelady nor Mr. Shelley puts Mr. Lovelady anywhere near the man in red seen in the Hughes film:
