Audio Analysis Is Most Consistent Two Shooters At Trump Rally

I simply zoom in on whatever picture and then use the windows screen grab tool by holding down the [shift] and [windows] key and then pressing the [s]-key.

this will darken the screen and turn the mouse pointer into a cross with which you can identify a rectangle: you go to any of the corners of the rectangle area you want to grab, hold the main mouse button down (left mouse button for most users), drag your mouse to the diagonally opposite corner, release the mouse button, et voila: that rectangle has been copied to your clipboard…

then you go to the application you want to paste the image into, and you are done…

(I’ll have not so much time today. But I have to check my calculations, since I added up the segment’s length. I must check the accuracy.)

Amazing, there’s always something new to learn :nerd_face:
After all this years I have never come across this option. Thanks for letting me know!

I got the following calculation for distance.
Remark: for the Mach angle we need instantaneous speed.

Hi Rough_Country_Gypsy,

I found an old picture from you:

This seems like a very good photo to verify this topic, because you can clearly see the notches and you don’t have two fences…

So, I aligned my CAD system exactly in the same perspective as your camera and superposed your picture and everything matches up perfectly!

If you have more pictures, I would be glad to verify.

Thank you. I had no idea of this feature. See if this is any better…

YES!!! Thank you! It’s still not as clear as on my computer but you can now clearly see the top wire"V" I was referencing. That section is directly in line with Trump’s podium and window 3. Sorry, I’m just not too computer-savvy. I’ll redo the original post.

I downloaded the photo you shared @roger-knight with the cutout fence notches and yellow arrow. I’ve added the red arrow to point out the “V” shaped top wire. It’s the section of the fence where the top wire forms a prominent “V”. The notched-out fence is clearly in the section to the left of it.

What is clear if zoomed in is the section of fence that forms the top wire “V”. That’s the section that’s directly in line with Trump’s podium and window 3. You’re off by one section of the fence. Where the fence notches are located, they don’t line up with any of the windows or vents.

as long as you’re drone savvy we’re all more than happy :wink:
Feel free to ask if you have any computer related questions. I’m sure the forum here is willing to help.

step 7 review: I guess we should add h/c.

No, it doesn’t, Roger. Here’s another picture I took from an angle further west (1st pic). The notches are one section of fence to the east and don’t line up with the podium.

Here’s where I’m “STILL” at…

100% out on the window.

100% out on the vent. Mostly because the people working so hard to prove the vent couldn’t make it work and jumped immediately to the window (which is a much worse option).

I’ll wait for @howdoiknowthisinfo to produce the evidence for his 2nd shooter theory, but as of now, I still have Crooks as the sole gunman with assistance in planning and access. The only other evidence of a 2nd shooter is the sound analysis, which is subject in a court of law at best. Everything else is speculation with no hard evidence.

The last two things setting my BS meter off are (A) where the tenth shot came from and (B) where the backpack came from. I’ll set those out until the entire 2nd shooter hypothesis is concluded.

@daniloraf Thank you for compiling such a comprehensive table of ammo data!

By my calculations, using a muzzle to mic distance of 153 yards, the average velocity should be between 2465 and 2585 fps, which is 38 fps higher than the range you used.

I added a column to your table for average velocity, sorted the table by average velocity and then filtered it to show just those rows in the range of interest.

I was hoping to see something here that had a Pkg. Qty. of 50, but no luck with that. The mean of my calculated range is 2525 fps. Your favorite candidate is 30 above that but still seems perfectly reasonable.

I have checked my calculations.

calculation error
The error is insignificant (4E-10 fps).

Explanation: The total might be saturated when we add up a lot of numbers. So I used subtotals of subtotal. (Something like when the bank pays interest but you cannot have less than 1 cent.)

Who established that shot 10 was subsonic? Look at the DJStew video which was close to line of fire; it appears that the crack arrived at 5:09.06:

I think I hear crack-boom. When I filter out high frequencies, I see a boom at 5:09.205 and a reflection of the boom off of building 6 at 5:09.245:

Others have nice headphones and are good at discerning what they hear. Is this what you hear? If the initial sound was instead the boom, the echo off the building wouldn’t be so far out and bigger than the initial sound (in this frequency band). I think this has to be crack-boom-echo. And a normal-speed bullet.

Similar to Trumps ear and the bleachers, this time we have window 3 and the notches in the fence. These are two points clearly defined in space.

You can take any picture or video and the trajectory never changes. So similar to the first picture superposed with my CAD I could verify this picture to be in the same line as the shot.

I am able to exaclty align the picture and the direction of the roof lines show that the camera was at the left side viewing building 6 with a strong angle. Therefore it is correct that the shots comes from the right side.

But this picture is confusing because it is taken from an angle and the ground levels are not the same. Before the discussion gets heated up, maybe you have another picture, or you said you made a video of the fence?

I will do a complete different approch to prove that the notches are in line with the bullet line.

Please give me some more time… :slight_smile:

Yes, @offtheback , I agree. When I listen to the audio at 1/10 speed with good headphones (and no filtering), I hear a couple of thumps after the crack. But with the crack sound being so spread out, they are difficult to discern. You came up with crack + 145 ms and crack + 185 ms in your analysis. My numbers are 144 and 188 milliseconds, so, very close to yours.

I think the one at 188 ms is the boom that corresponds to the crack. I don’t know what the sound at 144 ms is.

I was just eyeballing to 5 ms, so your numbers may be more accurate than I attempted.

The two secondary sounds have almost the same shape. Since by definition no echo can arrive before the line-of-sight sound, the first one of the two has to be the boom. Upon measuring, the path length to building 6 and back is too long for 44 ms. There could be a reflector closer to the source (maybe back of the large video screen if shot taken by Hercules) that could account for a 50-foot longer path length of an echo.

I can’t see 800 yds, much less shoot at a target at 800 yds.

Back on topic, I know people will hunt wild boars with subsonic 300BO or other similar bullets out to 300, but that heavy bullet will drop a lot.

I struggle a lot with the idea that someone would have access to a ongoing business, set up a sniper rife, determine there’s a teeny tiny piece of fence in their way for a TBD target location, leave that room cut or modify the fence, and go back to the room where their sniper rifle is located and hunker down until the target is in place. No way that could be pulled off without a lot of time and help.

@greg_n given that DJStew would have been 60 feet or more from a line from the south barn to the ridge of building 6 and around 150 yards away, 144 ms might be an acceptable snick-boom for a 300 WinMag 250 gr bullet.
