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

It says that it was the southeast corner, which means that this is the Sniper's Nest.

But, it doesn't make sense. Bonnie Ray Williams said that they started at the west wall, and they were working east. And he indicated a very narrow strip as the amount they got done. 

Read his testimony:

"We were working from the west, coming this way, coming to the east." Are we supposed to presume that they covered that entire floor almost to the Sniper's Nest?

Look: they are saying that was the southeast corner, hence, it was the Sniper's Nest. Williams said they started at the west wall. They could not possibly have been building this floor in isolated islands. So, if the new floor reached almost to the Sniper's Nest starting at the west wall, it means they covered nearly the whole damn floor. That day. But why then did Williams indicate such a narrow area of coverage? It does not make sense, and nobody can finesse it into making sense.
