The salient point is it establishes when Brennan could begin to observe the TSBD. I gather you understand that is his significance as a witness. Don't you? He saw stuff happening.....we are establishing when he might have seen that stuff.....with some degree of accuracy using the ambulance references in the transcripts. Not his vague recollection of an estimated time. He saw a clock at 12.16pm. He also saw them pick up the man. I assume "them" refers to the ambulance staff. Unless you know of anyone else who "picked up the man". We know when that happened by cross reference to the transcripts.
As for my theory......you did well until point 1) after that you failed to summarise accurately. Sorry. Point 2 is incorrect from the information we have at hand that I explained previously.
Find out what we can agree on. Do you agree or disagree that Williams first day statement indicates he did not got back to the 6th floor but went with Jarman and Norman and "just after" they got there they saw the motorcade pass. Does this sound like around 12.25pm to you for their arrival? It was only a couple of hours since the assassination when he wrote that.
The salient point that you're trying to establish has no bearing on the outcome of events that day but I'll entertain you by producing a timeline that firmly establishes that Brennan's recollections of when he was sitting on the concrete ledge is pretty accurate. Let's begin with the time Brennan said he finished lunch;
Mr. BRENNAN. I finished lunch and I glanced at a clock--I don't know exactly where the clock is located--and noticed it was 12:18. So I thought I still had a few minutes, that I might see the parade and the President. I walked to the corner of Houston and Elm
From there he went to Houston St. and Elm St. This walk took him approximately 4 minutes.
Mr. BRENNAN. Crossed the street to the southwest corner of Houston and Elm.
Mr. BELIN. Do you have any estimate about how long it took you to get there?
Mr. BRENNAN. A possibility I would say more or less 4 minutes.
Mr. BELIN. And then what did you do when you got to the southwest corner of Houston and Elm?
Mr. BRENNAN. I stayed around a couple of minutes. There was a man having an epileptic fit, a possibility of 20 yards east--south of this corner. And they
were being attended by some civilians and officers, and I believe an ambulance picked him up
Here's the amended portion of the DPD radio log transcript (I have omitted only the portion which is inconsequential)
Caller: Conversation:
289 (not assigned) Give us an ambulance, 100 N. Houston St. - epileptic seizure
Dispatcher (MC DANIEL and HUFFSTUTTER) 10-4
289 (not assigned) Make it code - 3 (Emergency Red Lights and Sirens)
Dispatcher (MC DANIEL and HUFFSTUTTER) Be a white? (12:19)
Dispatcher (MC DANIEL and HUFFSTATTER) What's your location?
606 (ambulance) About Hardwood and Cedar Springs now
Dispatcher (MC DANIEL and HUFFSTATER) 10-4 Code 3. (Emergency-red lights and sirens) on a signal 28 (emergency sick call) 100, N. Houston 12:20
Dispatcher (MC DANIEL and HUFFSTATER) 10-4, 606 (Ambulance), 12:24
Dispatcher (MC DANIEL and HUFFSTATER) 606 (Ambulance)
606 (Ambulance) We are en route Parkland (garbled). This is a signal 16 (Investigation injured person)
By 12:24 the ambulance was already on it's way to Parkland. This falls pretty much in line with Brennan's timeline. He was sitting on the concrete ledge no later than 12:24.
What we can agree on is that BRW was not at the SN doing the shooting. Do you agree with both Givens and Danny Arce that BRW was not with them and Jarman before Jarman and Givens left?
Mr. BALL. Was Bonnie Ray Williams ever out there with you?
Mr. ARCE. No, he stayed upstairs with Hank. Junior stayed up there but he was down a little while and I guess he went upstairs.
Mr. BALL. What about Givens?
Mr. ARCE. He was down there with Shields, I guess---I mean Melvin---no, Carl, that's who he was with...?
Mr. BALL. What about Jack Dougherty?
Mr. ARCE. He was on all floors; I couldn't tell you where he was.
Mr. BALL. Was he outside?
Mr. ARCE. No, he was eating lunch; me and Jack Dougherty, same time.
Mr. BALL. Dougherty ate his lunch?
Mr. ARCE. Yes, sir.
Mr. BALL. Did he go outdoors after lunch? I don't know; I didn't see him. Who went outdoors with you? Bill Shelley and Billy Lovelady; Carl was out there and Charles. You stood there how long before the parade came along?
Mr. ARCE. I am not too sure; it was about 10 minutes, somewhere. around there. I am not too sure about that.
Looks like Arce and Givens had to be in on the cover up too
