LHO was in the building. WOW!
Yes, Getting Lee the job in the TSBD was the key factor in advancing the plot. And we now know that the major problem was getting Lee to actually go to the TSBD and apply for a job.... We now know that a job was there waiting for him and all that was required was that he go there and apply.
And personally I suspect that Lee thought that he was working undercover for the FBI who wanted information about the activities of Joe Molina who worked in the TSBD and was the leader of The American GI Forum, an organization that JE Hoover thought was a communist front organization.
At any rate Ruth Paine , who we now know was an FBI informer sent Lee to the TSBD to talk to Roy Truly. And Roy Truly hired Lee Oswald immediately even though the rush season was in the past, and Truly was using many of his men in projects other than processing school books .
We now know that a job was there waiting for him and all that was required was that he go there and apply.
Anybody who has studied the case is aware that Lee Oswald applied for a job at several places which were close to the parade route of the motorcade...... and it is a matter of record that someone at Love Feild had called Ruth Paine and informed her that they could use Lee Oswald as a baggage handler at Love Field ( I believe that the wage at Love Field was about 50% higher than the TSBD job. )
At any rate, if Lee had taken the job at Love Field he might have been in position to have been near JFK when AF1 landed there....
The point being...Was it mere coincidence that Lee applied for employment at many places that were near the Parade route?
