Yes and as he points out, the manner in which individuals do this is different. Which makes sense. At no time is McComas saying that they do not use the scientific method or a scientific method as you initially tried to claim.
It seems as though you have been duped by the quote mining form of "research" you do.
Wasn't
deserted.
There was a house right near the bridge where the car crashed into the water and at least one resident heard the accident, and when they went out to look, could not see it in the dark. Which makes sense, dark river, under a bridge and the dark underside of a car would have made it very difficult to see.
If you watch the second video on this link, you can see the house right next to the bridge as they pull the car out of the river and put it on a truck to take away.. Starts from about 1 minute into the video. Then the reporter discusses how one nearby resident had heard the accident.
The body-cam video you linked.. At 1:59, there is a very distant voice that appears to say "why won't somebody help..." And the police officer calls out "we're helping".. Then at around 2:08, I heard her voice again, but she said just one word and it was again distant and indistinct, as though she was standing far away, talking to someone.. Then at around 5:05 onwards, I hear the same voice, only not as muffled calling down to the rescuers - it is just before they remove the baby from her seat and then her voice is heard much clearer and much louder as it appears as though the woman who belongs to the voice has come down the hill to help carry the baby up said hill to the ambulance.
I listened to the video you linked and then the portion that Kitta linked and it wasn't the disembodied voice, but appeared to be coming from behind the officer, a voice talking and then later on, calling down to the officers as the baby was rescued.
Another thing to note, the voice heard on that body-cam is not saying what those police officers claimed they heard.
Also, there were bystanders on the bridge as this rescue attempt was taking place and if you listen to the 911 call that the fisherman made, he said that there was "
a car in the river and a person inside" the car (it's in the video attached to that story). So the rescuers were going there with the specific intent of rescuing a person trapped in an overturned car. But here is what was interesting:
"There were some individuals on top of the bridge, but all three stated [the voice] came from the vehicle," Johnson said. "It prompted us to lift the car between the three officers and firemen. They physically lifted the car from the side, and they located the infant in the car seat at that time."
The video you linked from the police body-cam clearly shows that it was a desperate attempt to get into that car from the moment he got there. There was no lull in their trying to get into the car and that is probably because the 911 call had said that there was a person inside the car. At all. And the body-cam footage also shows that when they weren't able to open the door, they decide to lift the car up onto its side.
