So many words and endless personal commentary, but again no answer to the simple question about YOUR conclusion that Oswald "didn't come down the stairs." We have reached an impasse.
We have reached an impasse. No we haven't. What we are dealing with here is your complete failure and/or unwillingness to provide evidence to support the claims you have made.
As for the simple answer to your question. It has been given a number of times already, but here it is again;
The preponderance of evidence clearly supports the conclusion that Oswald couldn't have come down the stairs, within 75 seconds after the last shot, and not be noticed. That's my opinion and it's based on the available evidence. You know, the evidence you don't want to discuss!
You just pretend we somehow have reached an impasse, so you can avoid providing the evidence for your claims that Oswald was on the 6th floor when the shots were fired and that he managed to go down the stairs unnoticed within 75 seconds of the last shot.
Chapter 4 of your bible, the WC Report, deals with the stairs matter simply by ignoring it completely and only makes assumptions not justified by the available evidence about Oswald being on the 6th floor. You, on the other hand, have claimed that Oswald was in fact on the 6th floor and did come down the stairs unnoticed.
You have now shown us, beyond doubt, that your claim was not only not credible but also based on no evidence whatsoever. The only reasonable conclusion has to be that you simply believe that Oswald was on the 6th floor based not on actual evidence but simply because you want him to be, regardless of the facts.
