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

Let's remember that we do know, beyond any doubt, that they DID weave different films together, that they took multiple clips from different films and spliced them together- repeatedly- to make it look like one continuous progression. 

That happened; we know it happened. Therefore, what is so terrible about asking whether it may have happened some more?

I'm not seeing it. But, let's keep looking:

I'm not seeing it, Backes. You think it's due to the settings? the type of camera? the lens?  Once more:

I don't see them being the same man, but according to Joseph Backes, it is an outrage to ask the question. Sure, we know they merged clips from different films into this sequence, but how dare I ask whether they did it here. Look again at the shoulders, Backes:
