Oswald in the doorway: the blog of the Oswald Innocence Campaign, by Ralph Cinque

Really, what we have here are two views of the Sniper's Nest, one from the northeast and the other from the southwest. And in each, there is a smidgen of installed plywood showing. However, it's impossible because in a job like this, you would start in one corner and work your way across in one continuous sweep. You certainly would not lay down flooring in isolated islands. Yet, we can plainly see that there is no continuity, that there is a massive gap between the two islands. 

Again, no one would lay down flooring that way. The whole floor-laying project on the 6th floor that day is highly suspect, and I think it had more to do with setting up the 6th floor for the coming event than anything else.
