How do you know what a cop was "hoping"?
It is logical.
So? How many people really knew that at that time?
Millions. The radio broadcasts kept stressing that the President and the Governor were wounded, both in critical condition with the doctors working to save their lives. No one reported either as DOA.
How do you know that the reference was to NBC 820 AM radio? TV was the main media at the time. Why must "we assume" there was an 820 broadcast?
Was the policeman E. G. Sabastian watching TV? The main NBC TV broadcast reporters were not set up to monitor the Dallas police department radio. Only the local news stations were set up to do that.
And because of the link I posted before:
http://www.dfwradioarchives.info/1960s.htmIn each of the years, 1960 through 1965, the NBC station was 820 AM, the ABC station was 570 AM. Sometimes the local station WBAP would be broadcasting on 820 AM for NBC. Sometimes it was WFAA. But when either was broadcasting for NBC it was always on 820 AM.
We know it was not on the NBC TV Broadcast. We know it was not on the national NBC radio broadcast out of New York, which I don’t know was available in Dallas on any station. That leaves the local NBC 820 AM frequency. To know that Mr. Brewer could not have heard such an announcement, we need a recording of the broadcast on that day for 820 AM. Without it, no one can say that Mr. Brewer could not have heard that announcement before Oswald showed up.
So, yes, you need to find the 820 AM broadcast to prove no NBC station made such an announcement.
At 1:30 all ears were glued to what was the fate of the president. What you are doing is basically stating that--- [using 1:15 as the time of the shooting] ---in less than 12 minutes!...some news report states the cop "DOA"! Now how was that humanly possible?You are a "CT" ? OK, But I am not. I am a skeptic. How do you know there was even a broadcast on 820?
Easy. Reporters compete the get out news as fast as possible. I have heard that several local stations monitor the police radio frequency. They might even have found out from hanging around police headquarters, a good place to be where reports are first funneled into. In any case, monitoring the police radio frequencies can allow them to get the information at the speed of light. They can have the news as soon as the police dispatcher did, within a minute or two.
I don’t know for certain if it did happen or not. Although if it didn’t happen, I’m mighty perplexed out how Officer E. G. Sabastian became convinced that it did happen and report this immediately. In any case, it is not impossible nor extremely unlikely. Mr. Brewer might get confused within the next two weeks. Officer E. G. Sabastian? That’s a harder sell.
As you mention ...there was a time share involved with the AM broadcasts--So the request may just be for some broadcast that didn't exist. The NBC broadcasting was given in replies #14 and the New York feed #18. You yourself posted the NBC TV feed. Why not just listen to them? If you hear about the policeman being shot please point out the section.
Reply # 14, for WBAP was the ABC feed. It said at the beginning, in the first minute, that it was an ABC broadcast, on 570 AM. Checking the ABC feed tells us nothing.
Reply # 18 was the New York NBC radio broadcast, which, as far as I know, was not even available in Dallas without a special radio. Checking the national NBC feed that a regular radio could not get in Dallas tells us nothing.
You need the NBC 820 AM broadcast, to eliminate the possibility of Mr. Brewer hearing it. Otherwise, with Officer E. G. Sabastian reporting immediately that he just heard such an NBC announcement, with Mr. Brewer saying within two weeks that he heard such an announcement, they probably both heard such an announcement.
I used to believe that Mr. Brewer probably could not have heard that announcement. New evidence caused me to change my mind. It will take new evidence to cause me to change it back.
