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

This concerns the inoperable elevators, in response to Joseph Backes, who is prone to ID-10T errors.

Yes, I know they were freight elevators with open shafts. But, everybody knew how the elevators worked, that you had to be sure to close the gate so that the next person could use the elevator. I'm sure they were not yelling up and down the elevator shaft all day long in the normal course of business. 

Truly just presumed that someone left the gate open since the elevator didn't work. But wait: they BOTH didn't work. How likely was it that both gates were left open accidentally?

And when they couldn't use the elevator, they took the stairs up to the 5th floor. And by the time they got there, the west elevator was already gone. So, shall we assume that someone showed up and closed it? Who? It was the 5th floor, and the only ones on it were Jarman, Norman, and Williams, and they didn't say anything about doing that. But, the east elevator was there, so Truly and Baker took it to go up to the 7th floor. But, was the gate open or closed? They didn't say, and Belin didn't ask. 

I think it's likely that the elevators were turned off centrally. They were electrical devices so there must have been a switch somewhere. And what about the fuses? At my house, there is a separate fuse for every electrical device: the electric furnace, the electric water heater, the electric stove, the refrigerator. So, I can turn off any single one by flipping the switch at the fuse box. 

The point is that it would be extremely naive to think that the incapacitation of both elevators was a random oversight that just happened to happen at that time. You'd have to be a complete idiot to think that. Somebody made sure those elevators were turned off, and it wasn't Lee Harvey Oswald.
