His original affidavit doesn't say how much time passed before he ate his lunch. In his WC testimony he indicated that he stood around for several minutes (he didn't say at the top of the steps) before going down to the basement.
Obviously I was being slightly frivolous in my post, hence the inclusion of Jimmy Hoffa.
I didn't realise it was going to be subject to rigorous analysis (I should've known better)
So allow me to clarify -
As I understand it from your post and what Alan has posted about Frazier's new book, Frazier is saying that after the shots he left the front entrance steps, walked towards the railroad yard, encountered Mr Brown and his rifle, walked back to the corner of Houston and Elm, saw Oswald, made his way back to the front entrance steps, went back in the TSBD and had his sandwiches.
In his affidavit he states that he "was standing on the front steps of the building when the Parade came by", after the shots he "stood there, then people started running by, and I turned, and went back in the building and got my lunch and eat it".
In his WC testimony he states he is stood on the front steps, "one step down from the top"" by the rail." After the shots he " just stood still". As he clearly states - "I just stood where I was. I hadn't moved at all." He stood there for a few minutes before going back in the building. He is very clear about staying exactly where he was after the shots - "I have always been taught when something like that happened or anywhere as far as that it is always best to stand still because if you run that makes you look guilty sure enough."
The point I was making was this - In his affidavit and WC testimony Frazier:
Does not leave the steps
Does not walk towards the railroad yard.
Does not see Mr Brown and his rifle.
Does not walk to the corner of Houston and Elm.
Does not see Oswald.
Does not return to the steps.
Frazier stays on the front steps then goes back inside the building.
He is back inside within a few minutes.
And he has two sandwiches.
