Euins' "bald spot" is certainly getting far more attention than it deserves. It seems to me entirely consistent with the gunman being Oswald. The only really salient point is that he most certainly saw a rifle being fired from the 6th floor window.
On 11-22-63, Euins described this as a "white spot," causing the person who prepared his Voluntary Statement to mistakenly have him saying he'd seen a white man. Euins clarified this when he testified before the WC.
His WC testimony, while impressively lowkey and unembellished, makes clear how little of the shooter he actually saw. To wit:
Mr. Mr. SPECTER. Now, what kind of a look, if any, did you have at the man who was there?
Mr. EUINS. All I got to see was the man with a spot in his head, because he had his head something like this.
Mr. SPECTER. Indicating his face down, looking down the rifle?
Mr. EUINS. Yes, sir, and I could see the spot on his head.
Mr. SPECTER. How would you describe that man for us?
Mr. EUINS. I wouldn’t know how to describe him, because all I could see was the spot and his hand.
Mr. SPECTER Was he slender or was he fat?
Mr. EUINS. I didn’t get to see him.
Mr. SPECTER. Could you tell from where you looked whether he was tall or short?
Mr. EUINS. No.
Mr. SPECTER. Of what race was he, Amos?
Mr. EUINS. I couldn’t tell, because these boxes were throwing a reflection, shaded.
Mr. SPECTER. Could you tell whether he was a Negro gentleman or a white man?
Mr. EUINS. No, sir.
Mr. SPECTER. Couldn’t even tell that? But you have described that he had a bald ...
Mr. EUINS. Spot in his head. Yes. sir; I could see the bald spot in his head.
Mr. SPECTER. Now, could you tell what color hair he had?
Mr. EUINS. No, sir.
Mr. SPECTER. Could you tell whether his hair was dark or light?
Mr. EUINS. No, sir.
Mr. SPECTER. How far back did the bald spot on his head go?
Mr. EUINS. I would say about right along in here.
Mr. SPECTER. Indicating about 2-1/2 inches above where you hairline is. Is that about what you are saying?
Mr. EUINS. Yes, sir, right along in here.
Mr. SPFCTER. Now, did you get a very good look at that man, Amos?
Mr. EUINS. No, sir, I did not.
Mr. SPECTER. Were you able to tell anything about the clothes he was wearing?
Mr. EUINS. No, sir.
So we're talking about a free-floating "bald spot" 2-1/2" into the hairline of an unspecified head with unseen hair. Quite possibly simply a reflection on Oswald's distinctly high forehead? Very likely, I would think.
What did Oswald's hairline look like, anyway? Was Euins' description consistent with Oswald's appearance? It certainly seems so to me. There are umpteen images showing Oswald's receding hairline.
