So Bill. Using your assumed timeline, and I think it's pretty accurate, then we can also make the assumption that the shooter was approached by Tippet at approximately 1:13pm. Keeping in mind that there was a discussion between the shooter and Tippet that maybe took a minute, maybe more, and then there was the actual shooting that maybe took 15 to 30 seconds. So if Tippets car approached the shooter at 1:13PM, the REAL question would be could Oswald have been able to walk from the rooming house to the shooting scene by 1:13PM. Given what the housekeeper gave as the time that Oswald left the rooming house, I'm not so sure that he could have made it to the scene in that amount of time on foot alone.
Bill's timeline can't be accurate for several reasons. The most obvious one is that the authorization for autopsy, which Gary posted, shows that Tippit was declared DOA at the hospital at 1:15 pm. DPD officer Davenport, who followed the ambulance part of the way and was present at the hospital confirms that time. Secondly, there is the combined timeline of Helen Markham and T.F. Bowley that does not compute with Tippit being killed after 1:10 pm at the latest.
No LNr has even tried to come up with a plausible scenario for Markham still being at 10th/Patton at 1:14 or 1:15 when she testified she left home "a little after 1" and the one block walk from her home on 9th street to the corner of 10th street and Patton would have taken her only 2, perhaps 3 minutes. Markham estimated in her testimony that she took the 1.15 bus to work every day, but according to the FBI the bus was scheduled to stop there at 1.12 and at 1.22. It actually doesn't matter which bus Markham was talking about, because a walk of two blocks to the bus stop would have taken her no more than 6 minutes. So, if she left home "a little after 1" she would have easily been at the bus stop at around 1.15 and thus not at 10th/Patton. In other words, Tippit must have been shot earlier than 1.15, most likely around 1.06, because otherwise Markham could not have witnessed it.
The same thing goes for Bowley. He arrived after Tippit was killed. In his affidavit he said he picked up his daughter at R.L. Thornton School in Singing Hills at "about 12:55". School bells, in my experience, have a tendency to ring at the correct time every day! Now, let's also not forget that, after picking up his daughter, Bowley was also going to pick up his wife from work, to go on a family holiday and thus had every reason to be on time and be aware of the time! The drive from the school to 10th/Patton is about 7 miles long and takes roughly 13 minutes, depending on the route, making it absolutely possible and plausible for him to arrive at 10th street at 1.10 pm, like he said he did in his affidavit. But even if we are kind to the LNs and accept that Bowley didn't pick up his daughter on time (leaving her waiting for 5 minutes or longer) and did not leave the school until 1 PM, he still would have arrived at 10th/Patton at 1:13, which of course would have been prior to the shooting of Tippit at 1:15, as the WC narrative claims.
And thirdly, according to J.C. Bowles, who was in charge of the DPD dispatchers, the times given verbally by the dispatchers (and thus copied in the transcripts) aren't reliable to determine the real time. This is what Bowles told the HSCA;
Two quotes from the same page:
http://www.jfk-online.com/bowles1.html#setA 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. There is no way to connect "police time" with "real time." The Committee Report stated that the Dallas Police Communications system was recorded by continuously operating recorders. That statement is incorrect. Channel 1 was recorded on a Dictaphone A2TC, Model 5, belt or loop recorder. Channel 2 was recorded on a Gray "Audograph" flat disk recorder. Both were duplex units with one recording and one on standby for when the other unit contained a full recording. Both units were sound activated. It is important to note "sound" rather than "voice" because either sound or noise from any source, received through the transmission line, would activate the recorders. Once activated, the recorders remained "on" for the duration of the activating sound plus 4 seconds. The four second delay permitted brief pauses or answers to questions without the relay mechanism being overworked. On occasion, the recorders would operate almost continuously because rapid radio traffic kept them operating. On November 22, 1963, the Channel 1 recorders became, for practical purposes, continuous recorders for just over five minutes starting at approximately 12:29 pm (Channel 1 time) because the microphone on a police motorcycle stuck in the "on" position. The resulting continuous transmission kept the Channel 1 recorders operating for just over five minutes thus giving us a real-time recording for that period. The only problem was determining a basis for an accurate time reference during that period. IMO the time Tippit was killed was pushed back as much as possible to allow for enough time for Oswald to cover the distance between the roominghouse and 10th street. A time trial by Gary Mack showed some years ago that the fastest time possible was 11 minutes.
