I already told you in the "Oswald probably did it" thread who the 4 people were who said they saw a gunman in a window. Hint: Worrell was not one of them. But when the topic of Mac Wallace came up, you asked what witnesses said they saw Mac Wallace. So it's fair to ask you then what witnesses said they saw Lee Oswald.
It's just Brennan then, right? And that was some time later after not identifying him in the lineup, right? Do you consider his change of heart to be reliable? I don't. Do you think that the details that Brennan described in great detail both in his testimony and in his book were things that he actually could or did see? I don't. For example, how did he see a gunman in firing position for the head shot from where he was sitting and see enough of him to estimate his height, weight, and clothing?
You have this tiresome obsession with Brennan. He saw different parts of Oswald over the course of two sightings.
How did he see a gunman in firing position for the head shot from the belt up?
He couldn't. His affidavit says:
"I then saw this man I have described in the window and he was
taking aim with a high powered rifle. I could see all of the barrel
of the gun. I do not know if it had a scope on it or not. I was
looking at the man in this windows at the time of the last explosion.
Then this man let the gun down to his side and stepped down out
of sight. He did not seem to be in any hurry. I could see this man
from about his belt up."
Cherry-picking his testimony gets one this:
"But at the time that he was firing the gun, a possibility from his belt up."
Which supposedly you take to mean him seeing "a gunman in firing position for the head shot from the belt up". Yet a review of his affidavit shows he meant that at the time of the final shot, he saw more of the assassin because the gunman stood up and stepped back.
How did he see 70-85% of the gun and not see a scope (if it was C2766)?
The scope is black and against a dark background. And the rifle is at an oblique angle to Brennan.
