And there’s no guarantee that Copenhaver didn’t move slightly to his gunshot location, or that Fox didn’t lie about the phone’s owner, because Fox lies about everything else, always.
Density of air and glass is different, and that affects the wave propagation. Density change separates the wave. There will be some reflected wave. So the sound energy will be partially reflected. But it is not the entire story. The window glass has a thickness. And at the other surface there will be another reflection, too.
But it is still not the whole story, now comes the repetiotion (like in hell), over and over and over again. Some fraction of the energy bounces back and forth. We need to add up infinite series of numbers.
And it is still not the entyre story either. There is a phase shift by each reflection. (And now it looks like a digital filter.)
Now back to muffled dashcam audio… from theoretical distance.
Feynman gave a lecture about light reflection and transmission in a theatrical and dramatic way. I have to watch it again, carefully.
First time it was weird and bizarre. Due to my bias - about photons and electrons.
They follow the statistics very accurately. Why? How? (Teachers say “categorical insufficiency” when one phenomenon is not the cause of the other, nor causal branching is there.)
However, when I tried the reflection-transmission problem with sound waves, it is pretty good.
Decades ago the official answer was: “shut up and calculate!”
But now some people, like Caltech professor Carroll, started asking formerly denied questions. I’m excited. After the decades of proud ignorance we might learn something new about the laws of nature.
I should appreciate the muffled audio problem.
Probably there was someone on AGR9 rooftop. But how did (s)he escape? There were law enforcement officers around the building complex - way before the shooting. And the medical helicopter flew over it. And the suit agent (Pardini) also walked around the roofs.
Additionally, I should do something about FFT issue. It is well known, chatGPT says. But still not mentioned in the simplified textbooks.
There are “fake” spectral lines - not intentionally, but as the result of inadequate tool used.
There were one or two other people here in the forum who came to the same conclusion with their calculations.
Even if you can’t understand the calculations, you should take note that no one could locate 2 shooters in different locations for the first 8 shots through audio analysis.
They have not located the second shooter.
Probably true, but the shooter would have been seen from the street during the shooting at the latest.
Crooks would probably have seen the shooter with his drone.
When is the shooter supposed to have left the roof?
That’s the grand conspiracy. There were law enforcement officers around. We’ve seen Sasse and Vensel. However, their bodycams weren’t on at western side. Allegedly we’ve seen two undercover cops walking around the building complex. (But those “ghosts” could be also rally goers early leaving the venue.)
From other hand, FBI stated they have obtained surveillance footages from nearby shops. But we have never seen those videos.
So it is still possible there was someone on AGR9 rooftop and quickly escaped after the shooting - at western side, like Crooks was able to access the roof.
They claim there was a drone in his car. But what we can see is only a second back pack.
However, there could be another drones a mile away. (But I think the distant footage at 1801 was made from a landing airplane.)
I don’t think the alleged 2nd shooter was wasting time so long.
Actually the calculation is a little simplified, and we don’t know the exact type of round have been shot. So it should be a big mess of probability calculations. (I struggle with accuracy issues almost every single day.) Unfortunatelly I don’t have accurate data to calculate anything. So maybe their approximations are correct, simply I don’t know.
Indisputable there were echo issues. Some shots had echo, some of then didn’t have.
It is a variation problem. If I had the correct pattern of the bullet and muzzle sound, maybe I would be able to find the best correlation. (Like I’ve tried it with the heights of the students.)
Once I worked out the calculation. It is elaborate, but maybe it falls to simple hyperbola. However, there are 3 DoF: the time of the bullet, the time of the shockwave from the bullet to the mic, and the muzzle sound (report) to the mic. The report and the shockwave travels with the speed of the sound, while the bullet has its own velocity. (I must think.)
We should locate the place of this footage made. Like these:
The Copenhaver video was released on the 31st July 2025. At that time, i zoomed in, and when they moved their heads to talk to each other i noticed them. I know there was another guy further along the roofline, and eventually found him on another video. For a very long time, i believed these three guys were the snipers that fired audio shots 1 to 8. This is proved to be not the case. [I have circles these guys in yellow].
In the compehaver video, i have since discovered more guys on the rooftop. Because i did not expect to find anyone coming up through the roof panels. Two more guys holding rifles in a shooting position [Circled in red].
A while back. the lads on Twitter first reported this video to be faked. I did take another good look at the video and i have to agree with them. It has been tampered with and badly done.
The video is not good quality to be able examine it in more detail. I have managed to zoom in so far. I am not certain of this, it does not look like Crooks running across the rooftop instead someone inpersonating him. He also appears to be wearing something black perhaps a bullitproof vest, and also appeared to be wearing a facial mask.
The lads on Twitter have already tried to find the true location of the Copenhaver video. They never did, and one thing for certain, Copenhaver did not take the footage. Him holding up a camera in the bleachers is not fooling anyone.
