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

Over on Randy Gunter's site, James Richards provided this other clear image of the disputed spectator. 

I believe that the image on the right is a very sophisticated photographic manipulation to make Robert Adams look like the spectator. If you look at the facial expressions- what each is doing with his facial muscles, you see that center and left have the same expression, the same contractions of the facial muscles, which is a deeply ingrained and subconscious neuromuscular habit. However, the facial muscles of the man on the right are much more relaxed. He was a different man.  And what what would a postal worker be doing huddled with the other spooks? James Richards thinks that Rafael "Chi Chi" Quintero was there as well. They're calling it Spook Central. Lucien Conein was the spectator- not Robert Adams.
