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

Here is further speculation from Richard Hooke. And it is a lot more reasonable than saying it's a bookcase. And why exactly would some photographers turn their cameras on other photographers who were shooting at Oswald? 

Ralph,
this is just speculation (like the old days),

that inner door looks like it could have been the main door to that room;
if you cut out that part, inside the outer door; so now you just have Oswald next to the inner door
AND FLIP THAT  ...that may have been the way it really was in another room...

1. they took the clip of the lemming line-up of cops comming in, with Oswald in front toward Fritz's office
2. they inserted that clip into an empty photo of the squadroom with the table on the right and the clock at 2 o'clock
3. they put an embedded a mini clip of Lovelady, in his plaid shirt, at the table
4. they flipped a photo of Oswald, who was photo'd in another room, to be on the left so you can see him through the door
5. they never removed the inner real door in the flipped part of the photo (in the inner room next to Oswald)

*NOTE: the photo of Oswald being marched in, with his shirt hanging off, seems to be of lesser quality than the brighter photo of him in that inner room.
