We mutually agree on that point, quote ---->
I believe he was behind that glass door----------------and saw Mr Oswald go through that door and out on to the steps.
Am sitting here pondering how many times--prior to February 1964--he was making every good faith attempt to share his personal experience, and subsequent observations of the wrongly-accused standing right out there on those front entrance steps...which somehow fell upon deaf ears even within his own community. Considering his young age (17), perhaps many of his much older & wiser elders considered he was full of foolish talk. It wouldn't have been the first time, nor the last, when a young person will be largely ignored about their "perception" of an important event.
Of course, less than 48 days after November 22, 1963, his alarming-ramblings somehow made their way out of the comfy confines of his own community back down to the authorities who paid him a little visit ---->

From that day forward, I believe young Mr. Lewis saw the "light" and knew precisely which way the wind was blowing. We can add Mr. Molina & Mr. Frazier to the club as well.
*Sidebar: Though Mr. Lewis is listed in most documents as 17, the above document incorrectly aged him 4 years in merely a two month period.
A fascinating document, sir!
Same deal as with Messrs Shelley, Lovelady, Frazier and Molina, and with (IMO) Ms Carolyn Arnold-----------the 'investigating' authorities were
very exercised about front entrance witnesses who either said they had seen, or must have seen, Mr Oswald out front at the time of the shooting.
I reckon Mr Lewis denied having seen Mr Oswald from the start. But the 'investigating' authorities knew where he was and what he must have seen there. So they did 'due diligence' on him, as per the document you have linked to. Nasty stuff!
