Front entry doesn't make sense because it doesn't line up with Adams & Styles' descent of the steps or Truly & Bakers' entry in to the First Floor...
As can be seen in Couch/Darnell, Lovelady & Shelley are headed up to the Train Yard where they went back in to the Depository through the west entry doors...
Obviously, Adams & Styles squeaked out the rear exit just before Truly & Baker ran in and were on the stairs just ahead of where Oswald needed to be in his alleged run down from the 6th Floor...It was actually Mrs Garner who was the one who should have seen and heard Oswald but didn't from her spot on the 4th Floor landing...
Give O'meara the opportunity to present his case. It is Compelling and New. There is seldom anything New presented in the JFK Assassination. His Shelley/Lovelady "front door" scenario merits serious consideration.
