Williams said he heard TWO TWO TWO shots..... he then went to the WEST end of the 5th floor.
Jarman & Norman were with him....Wht didn't they hear the shots....
WHY the hell wouldn't he have told Jarman and Norman that the shots came from the sixth floor, so why were they looking out toward the railroad yard? And Why wouldn't Williams have told the first police officer he met that the shots had been fire from the sixth floor??
I believe that by the time Williams gave his affidavit he had learned that they had found TWO spent shells in the SE corner of the sixth floor and simply made up the tale about the shots from above....
Walt, John's posting of BRW's 11/22 affidavit pretty much sinks the boat about no shots from the 6th floor window.
There is real life verifiable evidence based on the information taken from the shells and rifle themselves that point to there only having been two shots. A key part of that evidence is supplied by Josiah Thompson's observation of all the other shells and also the FBI's report stating it was a mark from the chamber of the rifle. A mark is that is missing from the shell casing listed as CE 543 and CE 543 alone.
In the words of Chief Curry, no witness identified LHO. So, the question remains if the assassin is not LHO then who was it, but the shots came from the TSBD 6th floor window.
