Bill Chapman,
Out of character was that Jack D normally took the whole lunch break but on that day he went back to work early.
He was reliable enough to be the person who daily turned up early, get things going before others turned up at the TSBD.
His testimony (IMHO) reads like someone who was coached on what to say and screws it up because it doesn't match the truth.
He gives answer to questions that weren't asked. He constantly contradicts himself.
His reason for not watching the parade is absolute bull, is that he didn't think there would be enough space outside. Despite any number of TSBD employees watching from Windows from various floors.
He relates a garbled conversation with Piper that Piper has no recollection of.
He was not seen by BRW (or saw BRW) when BRW went from the 6th to 5th around 12:25
He was on 5th till after Truly and Baker left the lift well area on the 1st, leaving him at the rear of the 5th whilst Oswald had to be descending, if he were on the 6th so as to meet T&B.
Nothing here, moving along.....
