Sorry, but can’t see how Bowleys watch which he says he looked at when reaching the scene , could be 7 minutes slow.
And Markams clock would have to be similarly 7 minutes slow.
So that’s why I at least was offering double timing for Oswald so the timeline can work without having to impeach major WC witnesses.
Did Calloway ever agree with anyone making a suggestion that he must of heard the shots fired at 1:15?
And there is that pesky 1:15 DOA by the emergency doctor which is MOT the same as a physicians “estimate” of when Tippit was shot. The DOA document is simply noting what the time of the hospital clock was when the doctor announced the body is dead. That clock also would have to be 7 minutes slow if you believe that the Bowleys radio call was made at 1:17.
