No. It makes no difference to me. I believe that LHO sat in the nest hidden from view and silent while BRW ate his lunch further west. And if BRW had remained on the sixth floor, he most likely wouldn’t have known LHO was there until the shooting began. Then, after the shooting, LHO could have used the remaining bullet in the rifle to shoot BRW if he tried to stop his escape.
So we have established that the accumulated evidence means nothing and your opinion is based on "belief" of an unsupported narrative. Missing fingerprints that you don’t know of is part of your rebuttal. Not much else but acceptance of a proven liar by his own statements.
Williams was eating in the SN until about 12.25pm. There is ample evidence evidence in the assembled documentation that establishes that. You simply need to adjust your Oswald alone theory to accomodate for it. Or just continue to ignore the obvious inconvenient conclusions. I think we both know the route you will choose.
