Firstly, Martin, you keep dragging Bill Brown into a discussion we are having. What I'm putting forward has nothing to do with Bill Brown. The analysis of the DPD tapes that clearly prove the ambulance arrives before Callaway's call are my own work. Something I've not seen or heard anywhere else (which isn't to say it hasn't been done before)
Secondly, when I got my head around the timeline you were proposing I called it impressive because, as far as I'm concerned, it is.
It is a far better fit for all the testimony than anything I can come up with at the moment.
The main issues with it, as far as I can see, are (in order of importance):
1) The ambulance arriving before the Callaway call in the DPD tapes
2) Bowley arrives while Benevides is on the radio - Bowley is 1:10 PM, according to his watch, Benevides is calling at 1:16 PM according to DPD tapes. This is a time discrepancy of 6 minutes between the two and Bowles does not hint at anything even remotely like this.
3) You have Callaway calling 3 minutes after the shooting but the tapes have Callaway calling 3 minutes after Benevides tries to make his call. The impression I get from Bowles is that these discrepancies gradually increase over time and are then corrected. I do not see him saying that you can lose a minute or two every three minutes. It would make the system redundant.
"Ambulance 602 made it's code 6 call only seconds before Callaway used the radio"
If this is the case it clears away the main issue with your timeline. In an earlier post I demonstrated, using the order and number of interactions recorded on the DPD tapes, that there was a significant time difference between the ambulance arriving and Callaway's call. This is the post:
In my mind this is clearly longer than 6 seconds. This is a lot closer to a minute and supports the notion that as Callaway is stood looking at Tippit's body (as he testifies to doing) the ambulance arrives and Callaway helps load the body. This is also supported by Guinyard's testimony:
Mr. BALL. And what did Callaway do?
Mr. GUINYARD. He turned around and run back to the street and we helped load the policeman in the ambulance.
Mr. BALL. He ran back up to 10th Street, did you say?
Mr. GUINYARD. Yes.
Mr. BALL. Did you go with him?
Mr. GUINYARD. Right with him.
Mr. BALL. Did you see a police car there?
Mr. GUINYARD. Yes.
Mr. BALL. What did you see besides the police car?
Mr. GUINYARD. The police that was laying down in the front of the car.
Mr. BALL. A policeman?
Mr. GUINYARD. Yes.
Mr. BALL. Was he dead or alive at that time?
Mr. GUINYARD. He looked like he was dead to me.
Mr. BALL. What did you do?
Mr. GUINYARD. Helped put him in the ambulance.
The only way it might possibly work (in my mind) is if as soon as the ambulance sees the murder scene off in the distance they put in the call that they have arrived and the sirens on Callaway's call is 602 arriving. But this is still very problematic.
The main issues with it, as far as I can see, are (in order of importance):1) The ambulance arriving before the Callaway call in the DPD tapesThat's not a big issue as I have already explained to you and I'll do it again below
2) Bowley arrives while Benevides is on the radio - Bowley is 1:10 PM, according to his watch, Benevides is calling at 1:16 PM according to DPD tapes. This is a time discrepancy of 6 minutes between the two and Bowles does not hint at anything even remotely like this.The discrepancy is what it is. Either you conclude Bowley's watch was 6 minutes slow or you conclude that the time stamps of the DPD tapes is off by six minutes. To determine which conclusion is the correct one, you need to look at all the other events and see how they match. I argue that Bowley's scenario matches seamlessly with Markham's times as well as the information we know about Benavides' actions. To match the entire sequence of events with the DPD time stamps is impossible. For instance, if the ambulance left 10th & Patton at 1:19 for a two minute drive to the hospital, how can it arrive at 1:24 (according to Dale Myers) and how do you explain the two documents in which DPD officer Davenport confirms that Tippit was declared dead (DOA) in his presence at 1:15. It just doesn't fit.
Bowles didn't specifically say that the clocks could be 6 minutes wrong, but if you read his information more closely you will notice that the 6 minutes difference isn't all that impossible.
A master clock on the telephone room wall was connected to the City Hall system. This clock reported "official" time. Within the dispatcher's office there were numerous other time giving and time recording devices, both in the telephone room and in the radio room. Telephone operators and radio operators were furnished "Simplex" clocks. Because the hands often worked loose, they indicated the incorrect time. However, their purpose was to stamp the time, day and date on incoming calls. While they were reliable at this, they were not synchronized as stated in the Committee report. Therefore, it was not uncommon for the time stamped on calls to be a minute to two ahead or behind the "official" time shown on the master clock. Accordingly, at "exactly" 10:10, various clocks could be stamping from 10:08 to 10:12, for example. When clocks were as much as a minute or so out of synchronization it was normal procedure to make the needed adjustments. During busy periods this was not readily done.Note that Bowles does not say that the master clock's "official" time is the same as "real" time. Secondly he says that the clocks used by the dispatchers indicated the incorrect time and that it was not uncommon for for the time stamped on calls to be a minute to two ahead or behind the "official" time shown on the master clock. And he then adds that when the dispatcher's clocks were a minute or so out they needed adjustment, but in busy periods that was not always done.
So, if the dispatcher's clock could differ two minutes from the "official" time on the master clock, how much did they differ from the "real" time?
Bowles then continues by explaining that the digital clocks used by the dispatchers were not synchronized with any time standard.
In addition to the times stamped on calls by telephone operators, the radio operators stamped the "time" as calls were dispatched, and the "time" that officers completed an assignment and returned to service. Radio operators were also furnished with 12-hour digital clocks to facilitate their time references when they were not using call sheets containing stamped time. These digital clocks were not synchronized with any time standard. Therefore, the time "actual" and time "broadcast" could easily be a minute or so apart.
So, what we now have is a clock used by the dispatcher that could be off by two minutes from the "offical" time, which in turn was not "real" time and we have a time difference between "actual" time (whatever that is) and "broadcast" time.
And still that's not all. He also points out that dispatchers did not always give the correct time stamp when there was heavy radio traffic.
Next, consideration should be given to the methods of individual radio operators. A given operator at a given time might broadcast "time" a little early in one event then a little late the next. Accordingly, a call initiated at, say, 10:10 might be stamped at 10:13 by the dispatcher, only to have intervening radio traffic delay his broadcast. He might go ahead and announce the dispatch time as 10:13 and the digital clock then showed 10:14.He actually gives as example how a 10:10 event might be time stamped at 10:13 with the digital clock showing 10:14. This clearly demonstrates that it is fully possible that the dispatcher's clocks and time stamps could differ by as much as 3 to 4 minutes from the master clock's "official" time. If the master clock's time then was off by only two minutes from real time, you end up with time stamps that possibly differ 4 or 5 minutes and maybe even 6 minutes from real time.
Let's not forget that the time line not only says that Bowley's watch said 1:10 but also that Markham would have arrived at the corner of 10th and Patton at around 1:09. Without her seeing the shooting she would have continued walking to the bus stop on Jefferson where she would have arrived about 3 minutes later at about 1:12. And then of course there are the officers Poe and Joz who wrote in their report that they heard on the radio about Tippit's death at approximently 1:10
How unlikely a 6 minute time difference between real time and DPD dispatcher time stamps might seems, it has happened unless the above four people are all wrong.
3) You have Callaway calling 3 minutes after the shooting but the tapes have Callaway calling 3 minutes after Benevides tries to make his call. The impression I get from Bowles is that these discrepancies gradually increase over time and are then corrected. I do not see him saying that you can lose a minute or two every three minutes. It would make the system redundant.No I have Callaway arriving at the scene at roughly 3 minutes after hearing the shots. And I have already demonstrated that as far as real time is concerned the system was in fact redundant, but it served it's purpose of time stamping a sequence of events.
If this is the case it clears away the main issue with your timeline. In an earlier post I demonstrated, using the order and number of interactions recorded on the DPD tapes, that there was a significant time difference between the ambulance arriving and Callaway's call. This is the post:Have a closer look at the transcript, which starts at 1:19
We have the dispatcher calling out 1:19 twice. And just look how close the second code 6 call of ambulance 602 is to Callaway's radio call.

It all happens in less than a minute and I would argue that the code 6 call of the ambulance is made no more than 20 or 30 seconds before Callaway's radio call. But whatever the difference is, it has no major impact on my time line.
