Oh, no! What do we have without O'Donnell and O'Neill?
We have all of this:
The radio log states that when the assassination occurred, Curry, who was driving the lead car of the motorcade directly in front of President Kennedy’s limousine, stated, “Get men on top of the underpass, see what happened up there, go up to the overpass.”
Dallas County Sheriff Bill Decker and Secret Service Special Agent Winston Lawson, who were also in the lead car,
The hardtop sedan that was approaching the mouth of the Underpass (ie: possible echos).
further bolstered Curry’s adamant view about shots originating from in front of President Kennedy.
You yourself posted this in 2010:
"when Curry was interviewed by the news media on November 23, 1963,
he claimed that he “could tell from the sound of the three shots that they
had come from the Book Company’s building near downtown Dallas.”"
As soon as Curry issued the instructions to “get men on top of the underpass,” Decker stated, “I’m sure it’s going to take some time to get your men in there. Put every one of my men there. Notify Station 5 [Sheriff’s Office] to move all men available out of my department back into the railroad yard and try to determine what happened and hold everything secure until homicide and other investigators can get in there.”
Secret Service Special Agent Winston Lawson wrote in his Secret Service report on November 23, 1963, “Chief Curry gave instructions over his radio for officers to converge on the area where the incident occurred.”
There is no ambiguity in Lawson’s report, as the radio log clearly states that the area where Curry instructed his officers to “converge” was “on top of the underpass.”
Secret Service Special Agent Forrest Sorrels, who was in the lead car, wrote a report stating, “When I heard two more shots, I said ‘Let’s get out of here.’ I looked toward the top of the terrace to my right as the sound of the shots seemed to come from that direction.”
He testified to the Warren Commission that he “did not look back” at the Texas School Book Depository “because it was way back in the back.”
Your text above is also eleven-years-old.
Lawson doesn't say the shots came from in front:
"As the Lead Car was passing under this bridge I heard the first loud,
sharp report and in more rapid succession two more sounds like gunfire.
I could see persons to the left of the motorcade vehicles running away."
Sorrells thought Curry referred to "the building"; if Curry did it wasn't recorded:
"And the chief took his microphone and told them to alert the hospital,
and said, "Surround the building." He didn't say what building. He just
said, "Surround the building." And by that time we had gotten almost
in under the underpass, and the President's car had come up and was
almost abreast of us."
The first reference in the DPD tapes to where shots actually came from is: "A passer-by states the shots came from Texas School Book Depository Building."
