Here is an exerpt from Chapter One of “With Malice” by Dale Myers:
Former dispatch supervisor Jim Bowles used a stop watch and some mathematics to deduce a “real” time from the police recordings by comparing an arbitrary zero base-time with the recorded time announcements that followed. A similar technique was applied to the entire channel one recordings for this book. The study shows that with the exception of five areas, the rapid radio exchanges that occurred in the wake of the Kennedy assassination caused the channel one recorder to operate in an almost continuous fashion. The result is a virtual “running clock” on the events surrounding Tippit’s death and the arrest of Lee Harvey Oswald. It should be stressed that the recording contains no exact record of “real time.” What it does contain is a sequence of events whose relationship to one another can be measured. For example, a time check of 1:19 p.m. and a check of 1:22 p.m. do not necessarily relate to “real time,” yet a stop watch review of the tapes show that the two instances did occur three minutes apart. By applying a stop watch and some mathematics to the channel one recordings, and comparing the resulting sequence of events with the eyewitness accounts, a reasonably accurate reconstruction of the Tippit murder and its aftermath was possible. The result is the real-life detective story that follows.
This is what I was suggesting is possible earlier in this thread. Dale’s description is better than mine.
It should be stressed that the recording contains no exact record of “real time.” This alone makes everything that follows questionable.
What it does contain is a sequence of events whose relationship to one another can be measured. For example, a time check of 1:19 p.m. and a check of 1:22 p.m. do not necessarily relate to “real time,” yet a stop watch review of the tapes show that the two instances did occur three minutes apart. I understand the logic of what he is saying, but it is meaningless if he is still using the times called out by the dispatcher, because that ignores completely what Bowles told the HSCA about the time stamps not being reliable to determine "real time".
And, even worse, the transcripts show that no times were called between 12.55 and 1.04. After that the next time call is 1.07 and then between 1.12 and 1.15 there were no time calls. Those are gaps of 9 minutes, 3 minutes and 3 minutes respectively. And then there is the problem that the actual audio recordings demonstrate clearly that there was no continuous recording between 12.55 and 1.15 and there also is no event during that period that could pin point an exact time, so there is no way of knowing where to start the stopwatch Myers claimed to have used.
Myers concluded that Tippit was killed at 1.14. If he is using the time calls as a guide and the starting time of the dictabelt recording was off by three or four minutes, which IMO opinion, given what Bowles told the HSCA is not beyond being impossible, the real time could have easily be 1.10 or 1.11 and the DPD recordings would still match up, except of course for the time calls themselves.
By applying a stop watch and some mathematics to the channel one recordings, and comparing the resulting sequence of events with the eyewitness accounts, a reasonably accurate reconstruction of the Tippit murder and its aftermath was possible.
There is absolutely no way that Myers could have compared the DPD recordings with the eyewitness accounts, simply because those eyewitness accounts do not match with the transcripts.
But, and I am going out on a limb here, if you are prepared to look at the factual information honestly, I am willing to walk you through the "comparision" of the DPD transcripts with the eyewitness accounts.
