You're quite correct, I do have Dougherty in the frame for being Rowland's "man with the rifle", but you don't.
So neither of us believes that Mr Dougherty is telling the truth about what he saw up there. Got it.
So it's you who has to explain this discrepancy, not me.
What discrepancy? Mr Dougherty saw more than he told. Simple self-preservation, just like with Mr Williams.
Rowland's testimony has got nothing to do with it.
The testimonies of the officers who saw the SN before Fritz got there recall that the lunch remains were in/on the SN (something Williams lies about in his WC testimony).
Prove those lunch remains were Mr Williams'. Heck, prove they were even left there that day.
Wiliiams' WC testimony confirms the lunch remains were his
Sure------coached testimony from a man who changed his story as often as his clothes
and that he went down to the 5th about 12:20 PM
The WC testimonies of Jarman and Norman place themselves on the fifth around 12:25 PM
Yes-------an important piece of Mr Oswald's alibi for the shooting
after which time Williams joined them.
Not necessarily
All these testimonies, taken together, place Williams in the SN having his lunch until 12:25 PM at least.
Rowland's observation of an African American male in the SN around 12:15/16 PM can only refer to Williams who is placed there, at that time, by all the above testimonies.
Nonsense. Mr Rowland describes a man who simply does not fit Mr Williams. As in, his description is miles off. You can ignore if you wish, but it doesn't make the discrepancies go away. The man was either Mr Eddie Piper or a non-employee.
That Rowland doesn't really pay any attention to this person explains much about the discrepancies in his identification but the point is that his testimony doesn't place Williams there. It is simply confirmation of all the other testimonies.
Correction: Ms Hall doesn't say she sees a member of the "team" (Lol)
So who, if not a member of the team, do you think this hat-wearing man could be?
Correction: see above
I have seen above and lo, you still can't explain away Officer Baker's first-day affidavit!
"Solution" 
Yep---------you claimed that Mr Williams must have been involved because he was allowed to leave the sixth floor. I showed how silly that assumption is
