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

 "The black horizontal and vertical stripes, as well as the white areas, 
are seen in the Altgens photo, they form obvious square patterns 
(although, admittedly, the picture is a blurry image no matter who you 
think it is).  Oswald did not wear a shirt with contrasting light and dark 
areas.  Any photo of Oswald taken from a distance and wearing the brown 
shirt with the line patterns in it always looks like a solid color.  The 
Altgens photo was taken from a distance and the dark and light patterns 
are clear enough to see that it's a plaid shirt."  Allan Johnson

 Wow. I am really astounded by the magnitude of the falsehoods that people are willing to espouse, to put their names to. 

Oswald's shirt always looks like a solid color? That wasn't true even in 2013:

That is hardly a solid color, even though the legitimacy of that shirt I question. Look how stiff the collar is. Compare it to Oswald's, which was soft. So, what? Did they starch it? If so, who gave them the right? 

But, even back then, Oswald's shirt didn't photograph without showing contrast. 

Oswald's shirt has a grainy pattern. It also had worn, shiny areas which reflected the light and showed as white in the photo, as you can see above. The same thing happened in the Altgens photo except that in addition, it shows a lot of haze and distortion due to the extreme enlargement that was involved. Remember: the whole Altgens photo was small, and the size of Doorman's image was infinitesimal. So, we're talking about a huge blowup, which means a lot of haze and distortion. And, there was light reflection. The totality of that is what we're seeing on Doorman's shirt.

 There is NOTHING that matches between those two "patterns". And I put the word "patterns" in quotes because it's only a pattern on the right. On the left it's: haze, distortion, and light reflection. But try this: try to circle an area on Gorilla Man's shirt and then an area that corresponds to it on Doorman's shirt. I dare you. There isn't even a small area that matches. There is nothing. There is complete discord between the two.

plaid

noun \ˈplad\

: a pattern on cloth of stripes with different widths that cross each other to form squares
plaids : clothes with plaid patterns

You read the definition, right? So now, for the first time, in your life, you know what the fuck it means. Now: show me one square on Doorman's shirt. I can show you a lot of them on Gorilla Man's shirt. I could fucking play checkers on his shirt. Show me one square on Doorman's so-called plaid shirt.
