'The man in charge of the DPD dispatchers basically tells the HSCA that there is no guarantee that the times given by the dispatchers reflect the real time'
Whoa. Hold your horses and try to stay within the confines of my point for the moment: No matter who said 'no guarantee', that still means 'cannot dismiss', no matter how great a chance prior results may have favoured DPD time-dispatches.
Just how stupid are you? Read the damned website! Bowles dismissed it to the HSCA....
DPD dispatchers called out times which, at best, were "official time" and "official time" and real time are not the same thing.
Sorry to burst your bubble. The times mentioned on the DPD transcripts are unreliable. A powerful circumstantial case proves them to be wrong. Deal with it!
