CBS probably didn't realize that he'd screwed up on so many things until several years later.
Regardless, at least he got the "money shot" (pardon the pun): JFK had been shot in the head, JBC had been shot somewhere, and that Jackie had tried to jump out of the car or some-such thing.
Oh yeah, and that it happened in Dallas, Texas.
On Elm Street.
CBS, NBC, ABC ALL knew what was on the Zapruder film. Rather also said on World Wide TV that he could see Gov Connally being shot in the chest as he turned around toward JFK.
And for the record, NBC still refuses to release their Original Darnell and Wiegman Films. The Wiegman Film being vital as he did film the JFK Limo going under the Triple Underpass. The Tick/Tock of Wiegman capturing the JFK Limo is relative to a JFK Limo "Rolling Stop" or a flat-out "Stop". And of course, my discovery of Wiegman NOT Filming the "getaway" car being parked alongside the Island. That "getaway" car was traveling down the Elm St Ext while Wiegman was filming the Island.
