What was interesting, in those days the big TV cameras took about a half hour or so to warm up (vacuum tubes) and stabilize, so it was Audio only for a while before Cronkite could be televised.
Oddly enough the very very first reports - that blood was seen from his head, and Kennedy was most likely dead, was the most accurate. Everyone who was actually there knew it was mortal, it was just a matter of conveying that to the press. Certain national security concerns probably prompted the delays in the “official” announcement.
They did have some stray voltage, claiming a secret service agent had also been shot. That never happened, one wonders how that got reported.
On the NBC feed, you can hear Robert McNeil over the phone telling Frank McGee that JFK had died. McGee winced when he heard.
There was a lot of “fog of war” reporting. They also said a secret service agent was killed, and that LBJ himself was wounded.
Possibly misreporting of the JD Tippet shooting.
Mermirriman Smith, the UPI correspondent was in the Motercade. Everyone in the Modercadeckneq that he was dead, but this was the UPI Nulliten at 1: 36 PM: President Kennedy seriously wounded. Perhaps seriously, perhaps fatal by Assadians bullet.
