I spent years reading including on the Lancer forum before even registering at a forum and I even brought it up on the old forum. I registered exactly on the fiftieth anniversary.
I do not recall anybody suggesting that Oswald did in fact have a mission to comply with in that building which was not in order to kill Kennedy. Walt reacted to this, he may have thought on it earlier on, I don't know.
This could amongst other things explain the problem as exposed in my "nightmare question number one".
Personally I do not see Oswald being set up without his whereabouts being under control. You do apparently.
During the WC investigation there was already discussion about Oswald being in some way affiliated with an intelligence entity. There is, and always has been, speculation about his presence dead smack in the middle of the offices of all sorts of intelligence agencies in New Orleans. The fact that he was able to summon an FBI agent to come and see him in jail after his arrest in New Orleans and J. Edgar Hoover's memo from (I believe 1960) that somebody else might be using Oswald's identity. All this and more has been discussed over and over again.

Personally I do not see Oswald being set up without his whereabouts being under control. You do apparently.Yes, I do think it would have been possible to set up Oswald without his whereabouts being under control as long as two conditions were met; (1) before going ahead with the murder, the conspirators would have needed to be sure that Oswald was in fact in the building. If he wasn't they would be able to abord. And (2) the conspirators would have needed to have back up from a cover up to resolve any problem that might arise re witnesses who saw something they shouldn't have seen.
As far as the latter is concerned, just how many witnesses were told they were mistaken? What happened to the man several people saw running down the grassy knoll and get into a car? Nothing, that's what happened. What happened to Carolyn Arnold's initial statement that she saw Oswald at the second floor lunchroom at 12:25? In a second statement at a later date the time changed to 12:15.....
