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

Upperpunk posts this comparison repeatedly, and I presume he thinks it demonstrates the same pattern.

I don't see that as being the same pattern at all. Doorman's collar seems pattern-less and his shirt otherwise just looks vaguely varied but without a single box or crossing line. 

And I did one of my own just to compare.

They aren't the same at all. 

Do we see any vertical white lines on Doorman? Nope. Not a one. Do we see any horizontal white lines? Nope, not a one. They would have to be extremely fine to match the white lines on the plaid shirt. What we are seeing on Doorman is just haze, distortion, and light reflection. It was an old shirt with thin, shiny areas which reflected light. It's not a plaid pattern. Try playing Checkers on it and see how far you get. 

This is really ridiculous. The bloodied, Kennedy-killing bastards will just bold-faced lie. Fact: Doorman's shirt is not plaid, not by any stretch of the imagination- and Upperpunk is stretching imagination past the breaking point. Fact: Lovelady did not wear a plaid shirt, but rather, a striped one, but even if he did, it wouldn't matter because Doorman's shirt is neither plaid nor striped. Fact: we have a perfect match of the shirt and the man found right here:

On the right, it is a HUGE blow-up, so naturally there is some distortion when you separate those pixels. But, in addition, Oswald was in the bright sun at that time with the light sparkling and reflecting off the shirt. But, on the left, he was indoors. And of course, it was a close-up picture. The differences we see in the "pattern" can easily be accounted for by these factors.

Upperpunk, you are aiding and abetting the killers of JFK as well as the framers of Lee Harvey Oswald, and that is a crime in the eyes of the law and a sin in the eyes of God.
